12Core and Builtins
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.
40
Collin Winter001a3952010-03-18 21:54:01 +000041- Code objects now support weak references.

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

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

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.)

197 function declaration, which was kept for backwards compatibility reasons,
198 is now removed (the macro was introduced in 1997!).
199
Larry Hastings402b73f2010-03-25 00:54:54 +0000200- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000201 from Python 3.1. All existing Python CObjects in the main distribution
202 have been converted to capsules. To address backwards-compatibility
203 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

Georg Brandlba83f822010-03-14 09:50:54 +0000449 file position when calling `truncate()`. It would previously change the file
450 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000451 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

547Core and Builtins
548-----------------
549
Georg Brandlba83f822010-03-14 09:50:54 +0000550- The ``__complex__()`` method is now looked up on the class of instances to
551 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000552
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000553- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
554 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
555
Mark Dickinson1b34d252010-01-01 17:27:30 +0000556- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000557 DeprecationWarning when passed a float argument where an integer was expected.
558 These functions and methods now raise TypeError instead. The majority of the
559 effects of this change are in the extension modules, but some core functions
560 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
561 and many unicode/str methods.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000571- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
572 used to drop the time part of the result.
573
Georg Brandlba83f822010-03-14 09:50:54 +0000574- Issue #1811: Improve accuracy and cross-platform consistency for true division
575 of integers: the result of a/b is now correctly rounded for ints a and b (at
576 least on IEEE 754 platforms), and in particular does not depend on the
577 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000578
Georg Brandlba83f822010-03-14 09:50:54 +0000579- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
580 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
581 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000582

Ronald Oussoren92919a62009-12-24 13:30:58 +0000584 executables on OSX.
585
Georg Brandlba83f822010-03-14 09:50:54 +0000586 These executables now work properly with the arch(1) command: ``arch -ppc
587 python`` will start a universal binary version of python in PPC mode (unlike
588 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000589
Georg Brandlba83f822010-03-14 09:50:54 +0000590- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

Georg Brandlba83f822010-03-14 09:50:54 +0000726- Issue #3382: 'F' formatting for float and complex now convert the result to
727 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
728 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000729
Georg Brandlba83f822010-03-14 09:50:54 +0000730- Remove switch from "%f" formatting to "%g" formatting for floats larger than
731 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000732
Georg Brandlba83f822010-03-14 09:50:54 +0000733- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
734 1e-100 used to raise OverflowError, but now gives the requested 120
735 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +0000744- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
745 decimal string that's guaranteed to round back to x under correct rounding
746 (with round-half-to-even rounding mode). Previously it gave a string based on
747 rounding x to 17 decimal digits. repr(x) for a complex number behaves
748 similarly. On platforms where the correctly-rounded strtod and dtoa code is
749 not supported (see below), repr is unchanged.

752 conversions within Python are now correctly rounded. Places these conversions
753 occur include: str for floats and complex numbers; the float and complex
754 constructors; old-style and new-style numeric formatting; serialization and
755 deserialization of floats and complex numbers using marshal, pickle and json;
756 parsing of float and imaginary literals in Python code; Decimal-to-float
757 conversion.

Georg Brandlba83f822010-03-14 09:50:54 +0000759 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
760 providing correctly-rounded strtod and dtoa C functions. This code is
761 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
762 the C compiler. There may be a small number of platforms on which correct
763 operation of this code cannot be guaranteed, so the code is not used: notably,
764 this applies to platforms where the C double format is not IEEE 754 binary64,
765 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
766 and Python's configure script is unable to determine how to change the FPU
767 precision. On these platforms conversions use the platform strtod and dtoa,
768 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000770- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
771 uses the correctly-rounded string <-> float conversions described above (when
772 available), and so produces correctly rounded results that will display nicely
773 under the float repr. There are two related small changes: (1) round now
774 accepts any class with an ``__index__()`` method for its second argument (but
775 no longer accepts floats for the second argument), and (2) an excessively
776 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
777 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000995 untrackable objects are not tracked by the garbage collector. This can reduce
996 the size of collections and therefore the garbage collection overhead on

Georg Brandlba83f822010-03-14 09:50:54 +00002357 - If x is not an int, long or float, then packing x will always result in
2358 struct.error. Previously an x with an __int__ method could be packed by
2359 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2360 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2361 neither __int__ nor __long__, TypeError used to be raised (with a
2362 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2363 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00002365 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
2366 argument with an __int__ method can be packed, but use of this feature
2367 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002560- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2561 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2562 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2563 ``printf`` function, whereas PyString_FromFormat has an independent
2564 implementation and uses "%zd" on all platforms for size_t values.
2565 This makes a difference on win64, where ``printf`` needs "%Id" to display

2661 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2662 for catch_warnings() also led to an improvement in the raising of a
2663 DeprecationWarning related to warnings.warn_explicit().
2664

2687
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002688- Issue #2975: When compiling several extension modules with Visual Studio 2008
2689 from the same python interpreter, some environment variables would grow
2690 without limit.
2691
Benjamin Peterson37346b22008-08-23 20:27:43 +00002692- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002729What's New in Python 2.6 beta 3?
2730================================
2731
Barry Warsaw07a4a382008-08-21 01:15:08 +00002732*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002733
2734Core and Builtins
2735-----------------
2736
Guido van Rossumf8402962008-08-20 15:01:50 +00002737- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2738 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2739 extensions do not automatically benefit from the class attribute
2740 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2741 to their tp_flags field if they care. This is a backwards
2742 compatibility feature; in 3.0, all types will use the cache by
2743 default.
2744
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002745- Keyword arguments can now follow starred arguments. (``f(a, *args,
2746 keyword=23)`` is now valid syntax.)
2747
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002748- ctypes function pointers that are COM methods have a boolean True
2749 value again.
2750
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002751- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2752 by denying s# to parse objects that have a releasebuffer procedure,
2753 and introducing s*.
2754
Georg Brandl1e13ea92008-08-11 09:07:59 +00002755- Issue #3537: Fix an assertion failure when an empty but presized dict
2756 object was stored in the freelist.
2757
Mark Dickinsonb6467572008-08-04 21:30:09 +00002758- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2759 ValueError consistently across platforms.
2760
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002761- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2762 (64bit Unix, for example), unichr() would truncate its argument and return
2763 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2764
Neal Norwitze7d8be82008-07-31 17:17:14 +00002765- Apply security patches from Apple.
2766
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002767- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2768 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2769
Antoine Pitrou92f82162008-07-25 22:22:08 +00002770- Issue #1819: function calls with several named parameters are now on
2771 average 35% faster (as measured by pybench).
2772
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002773- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2774 the python debugger steps into a class statement: the free variables (local
2775 variables defined in an outer scope) would be deleted from the outer scope.
2776
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002777- Issue #2620: Overflow checking when allocating or reallocating memory
2778 was not always being done properly in some python types and extension
2779 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2780 all been updated to perform better checks and places in the code that
2781 would previously leak memory on the error path when such an allocation
2782 failed have been fixed.
2783

2785-------
2786
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002787- Issue #3612: Added some missing basic types in ctypes.wintypes.
2788
Benjamin Petersone977ad42008-08-20 01:42:01 +00002789- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2790 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2791
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002792- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2793 version reported by these tools does not necessarily follow the python
2794 version numbering scheme, so the module is less strict when parsing it.
2795
Nick Coghlanf70385a2008-08-18 12:42:46 +00002796- Issue #2235: Added Py3k warnings for types which will become unhashable
2797 under the stricter __hash__ inheritance rules in 3.0. Several types
2798 which did not meet the rules for hash invariants and were already
2799 unhashable in 3.0 have now been explicitly flagged as unhashable in
2800 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2801 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2802
Brett Cannon88f801d2008-08-18 00:46:22 +00002803- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2811
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002812- Issue #3575: Incremental decoder's decode function now takes bytearray
2813 by using 's*' instead of 't#'.
2814
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002815- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002816 fails unicode conversion on 2nd parameter. (windows only)
2817
Facundo Batista94f243a2008-08-17 03:38:39 +00002818- Issue 2464. urllib2 now supports a malformation in the URL received
2819 in a redirect.
2820
Brett Cannonabe423e2008-08-16 21:47:07 +00002821- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002822 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002823
Facundo Batistaeb90b782008-08-16 14:44:07 +00002824- Issue #2776: fixed small issue when handling an URL with double slash
2825 after a 302 response in the case of not going through a proxy.
2826
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002827- Issue #2676: in the email package, content-type parsing was hanging on
2828 pathological input because of quadratic or exponential behaviour of a
2829 regular expression.
2830
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002831- Issue #3476: binary buffered reading through the new "io" library is now
2832 thread-safe.
2833
Brett Cannonbf3157b2008-08-14 05:00:03 +00002834- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2835 since mimetools itself is deprecated. Because modules are cached, all
2836 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2837
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002838- Issue #3134: shutil referenced undefined WindowsError symbol.
2839
Robert Schuppenies14646332008-08-10 11:01:53 +00002840- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2841 menu entries were not deleted.
2842
Brett Cannon83e81842008-08-09 23:30:55 +00002843- Copied the implementation of reduce() to _functools.reduce() to have a
2844 version that did not raise a DeprecationWarning under -3.
2845
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002846- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2847 a MemoryError rather than silently stop the iteration.
2848
Guido van Rossum59ce9012008-08-09 14:55:34 +00002849- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2850 to _sre.compile() will now be rejected. This should not affect anybody
2851 since the re.compile() function never generates invalid re-bytecode.
2852
Skip Montanaroa032bf42008-08-08 22:52:51 +00002853- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00002857- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2858 the reload() built-in has been removed.
2859
Brett Cannon7e30b672008-08-04 21:52:25 +00002860- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002861 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002872 asking for a specific length. This problem only affected files opened
2873 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002874

2899 file name rather than a ZipInfo instance, so files are extracted with
2900 mode 0600 rather than 000 under Unix.
2901
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002902- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002923What's New in Python 2.6 beta 2?
2924================================
2925
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002926*Release date: 17-Jul-2008*
2927
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002928Core and Builtins
2929-----------------
2930
Georg Brandl3e483f62008-07-16 22:57:41 +00002931- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2932 its methods now allow for items objects that can be converted to
2933 an integer using operator.index().
2934
Mark Dickinson64b7e502008-07-16 09:40:03 +00002935- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2936 produced a ValueError instead of giving the correct float.
2937
Eric Smitha5fa5a22008-07-16 00:11:49 +00002938- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2939 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2940
Mark Dickinson7103aa42008-07-15 19:08:33 +00002941- Issue #3008: the float type has a new instance method 'float.hex'
2942 and a new class method 'float.fromhex' to convert floating-point
2943 numbers to and from hexadecimal strings, respectively.
2944
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002945- Issue #2235: __hash__ is once again inherited by default. To allow
2946 collections.Hashable to remain meaningful in the presence of the
2947 default hash implementation (object.__hash__), it is now possible
2948 to explicit block inheritance of hash by setting __hash__=None at
2949 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2950 level.
2951
Nick Coghlanb028f502008-07-13 14:52:36 +00002952- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2953 the parent module cannot be found while performing an absolute import.
2954 This means that an incorrectly defined __package__ attribute will
2955 now only prevent relative imports in that module rather than causing
2956 all imports from that module to fail.
2957
Nick Coghlan14ff9942008-07-08 14:21:42 +00002958- Issue #2517: Allow unicode messages in Exceptions again by correctly
2959 bypassing the instance dictionary when looking up __unicode__ on
2960 new-style classes.
2961
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002962- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2963 set to a custom object whose write() method happens to install
2964 another file in sys.stdout.
2965
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002966- Issue #3088: Corrected a race condition in classes derived from
2967 threading.local: the first member set by a thread could be saved in
2968 another thread's dictionary.
2969
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002970- Issue #3004: Minor change to slice.indices(): the start and stop
2971 arguments are now treated identically, making the behaviour easier
2972 to describe and understand. For example, slice(None, -10,
2973 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2974 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2975 10, -1).
2976
Georg Brandl278fc502008-07-19 12:46:12 +00002977- Issue #3219: Calling a function with repeated keyword arguments,
2978 f(a=2, a=23), would not cause a syntax error. This was a regression
2979 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002980
Georg Brandl278fc502008-07-19 12:46:12 +00002981- Issue #2862: Make int and float freelist management consistent with
2982 other freelists. Changes their CompactFreeList apis into
2983 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002984
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002985Library
2986-------
2987
Thomas Heller57adf222008-08-14 19:10:48 +00002988- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2989 api functions without holding the GIL, which could lead to a fatal
2990 error when they failed.
2991
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002992- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
2993

Jesse Noller13e9d582008-07-16 14:32:36 +00003000- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3001 ForkingPickler.register() to resolve conflict with ctypes.
3002
Vinay Sajip51e65192008-07-18 09:01:10 +00003003- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003004
Thomas Heller880f5292008-07-15 19:39:38 +00003005- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3006 a valid dlerror() message.
3007
Thomas Heller2bad6572008-07-15 17:19:50 +00003008- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3009 incomplete structure was created.
3010

3014
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003015- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003016
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003017- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3018 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003019 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003020 content-length. The problem had been corrected in the 2.4 branch, but never
3021 merged into trunk.
3022
Georg Brandle78fbcc2008-07-05 10:13:36 +00003023- Issue #2663: add filtering capability to shutil.copytree().

3029- Issue #1746: Correct handling of zipfile archive comments (previously
3030 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00003031 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00003032
Vinay Sajip51e65192008-07-18 09:01:10 +00003033- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003034 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003035
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003036- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3037 handling is now the same as that of other special attributes like __name__).
3038
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003039- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00003491- Issue #1631171: Re-implement the 'warnings' module in C (the
3492 original Python code has been kept as backup). This will allow for
3493 using the 'warning's machinery in such places as the parser where
3494 use of pure Python code is not possible. Both the ``showarning()``
3495 and ``formatwarning()`` gain an optional 'line' argument which is
3496 not called by default for backwards-compatibility reasons. Setting
3497 ``warnings.showwarning()`` to an implementation that lacks support
3498 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003561- Issue #2550: The approach used by client/server code for obtaining
3562 ports to listen on in network-oriented tests has been refined in an
3563 effort to facilitate running multiple instances of the entire
3564 regression test suite in parallel without issue.
3565 test_support.bind_port() has been fixed such that it will always
3566 return a unique port -- which wasn't always the case with the
3567 previous implementation, especially if socket options had been set
3568 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3569 new implementation of bind_port() will actually raise an exception
3570 if it is passed an AF_INET/SOCK_STREAM socket with either the
3571 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3572 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3573 the socket it's been passed. This currently only applies to
3574 Windows. This option prevents any other sockets from binding to the
3575 host/port we've bound to, thus removing the possibility of the
3576 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3577 when a second SOCK_STREAM socket binds and accepts to a host/port
3578 that's already been bound by another socket. The optional preferred
3579 port parameter to bind_port() has been removed. Under no
3580 circumstances should tests be hard coding ports!
3581
3582 test_support.find_unused_port() has also been introduced, which will
3583 pass a temporary socket object to bind_port() in order to obtain an
3584 unused port. The temporary socket object is then closed and
3585 deleted, and the port is returned. This method should only be used
3586 for obtaining an unused port in order to pass to an external program
3587 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3588 a parameter to a server-oriented class that doesn't give you direct
3589 access to the underlying socket used.
3590
3591 Finally, test_support.HOST has been introduced, which should be used
3592 for the host argument of any relevant socket calls (i.e. bind and
3593 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003594
3595 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003596 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003597 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3598 test_asynchat and test_socket_ssl.
3599
Georg Brandl3ee81df2008-05-17 18:14:43 +00003600 It is now possible for multiple instances of the regression test
3601 suite to run in parallel without issue.

3757 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00003758 platform.machine() and platform.processor() will report this
3759 information as well.

3868-----------------
3869
Fred Drakea8ee94b2008-03-01 02:45:07 +00003870- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003871 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003872
Georg Brandlad61bc82008-02-23 15:11:18 +00003873- Issue #2067: file.__exit__() now calls subclasses' close() method.
3874
3875- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003876
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003877- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003878 issue 215555 for a discussion.
3879
Eric Smitha73fbe72008-02-23 03:09:44 +00003880- Added the future_builtins module, which contains hex() and oct().
3881 These are the PEP 3127 version of these functions, designed to be
3882 compatible with the hex() and oct() builtins from Python 3.0. They
3883 differ slightly in their output formats from the existing, unchanged
3884 Python 2.6 builtins. The expected usage of the future_builtins
3885 module is:
3886 from future_builtins import hex, oct
3887
Eric Smith7ef40bf2008-02-20 23:34:22 +00003888- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3889 exponents for exponents with absolute value < 100. Follows C99
3890 standard. This is a change on Windows, which would use 3 digits.
3891 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3892 so that any alterations it does to the resulting string will be
3893 available in stringlib/formatter.h (for float.__format__).
3894
Eric Smith5a3c1352008-02-19 13:21:56 +00003895- Implemented PEP 3101, Advanced String Formatting. This adds a new
3896 builtin format(); a format() method for str and unicode; a
3897 __format__() method to object, str, unicode, int, long, float, and
3898 datetime; the class string.Formatter; and the C API
3899 PyObject_Format().
3900
Georg Brandl3ee81df2008-05-17 18:14:43 +00003901- Fixed several potential crashes, all caused by specially crafted
3902 __del__ methods exploiting objects in temporarily inconsistent
3903 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003904
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003905- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003906 prevent a possible crash: an Abstract Base Class would try to access
3907 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003908

Georg Brandl3ee81df2008-05-17 18:14:43 +00003912- Clear all free lists during a gc.collect() of the highest generation
3913 in order to allow pymalloc to free more arenas. Python may give back
3914 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003915
Georg Brandl3ee81df2008-05-17 18:14:43 +00003916- Issue #2045: Fix an infinite recursion triggered when printing a
3917 subclass of collections.defaultdict, if its default_factory is set
3918 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003919
Christian Heimesf75dbef2008-02-08 00:11:31 +00003920- Fixed a minor memory leak in dictobject.c. The content of the free
3921 list was not freed on interpreter shutdown.
3922
Georg Brandl21e99f42010-03-07 15:23:59 +00003923- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003924 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003925
Georg Brandl3ee81df2008-05-17 18:14:43 +00003926- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3927 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003928 to compact the internal free lists of pre-allocted ints and floats.
3929
Georg Brandl3ee81df2008-05-17 18:14:43 +00003930- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3931 calls. Python expected the return type int but the fork familie
3932 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003933
Georg Brandl3ee81df2008-05-17 18:14:43 +00003934- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3944 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003945
Georg Brandl3ee81df2008-05-17 18:14:43 +00003946- Patch #1473257: generator objects gain a gi_code attribute. This is
3947 the same object as the func_code attribute of the function that
3948 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003949
Georg Brandl3ee81df2008-05-17 18:14:43 +00003950- Issue #1920: "while 0" statements were completely removed by the
3951 compiler, even in the presence of an "else" clause, which is
3952 supposed to be run when the condition is false. Now the compiler
3953 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003954
Guido van Rossumeead05f2008-01-24 18:21:02 +00003955- A few crashers fixed: weakref_in_del.py (issue #1377858);
3956 loosing_dict_ref.py (issue #1303614, test67.py);
3957 borrowed_ref_[34].py (not in tracker).
3958
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003959- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003960 suppressed while an extension is loaded by calling SetErrorMode in
3961 dynload_win.c. The error is still reported properly.
3962
Georg Brandl3ee81df2008-05-17 18:14:43 +00003963- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003964 several extension methods and modules do not work without unicode
3965 support.
3966
Georg Brandl26543b12008-01-21 18:36:51 +00003967- Issue #1882: when compiling code from a string, encoding cookies in the
3968 second line of code were not always recognized correctly.
3969
Georg Brandl14404b62008-01-19 19:27:05 +00003970- Issue #1679: "0x" was taken as a valid integer literal.
3971
Georg Brandl6caad7d2008-01-26 14:19:22 +00003972- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003973 added.
3974
Christian Heimesc94e2b52008-01-14 04:13:37 +00003975- sys.float_info / PyFloat_GetInfo: The floating point information
3976 object was converted from a dict to a specialized structseq object.
3977
Georg Brandl3ee81df2008-05-17 18:14:43 +00003978- Patch #1816: Added sys.flags structseq. It exposes the status of
3979 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003980
Georg Brandl3ee81df2008-05-17 18:14:43 +00003981- Objects/structseq.c: Implemented new structseq representation. The
3982 patch makes structseqs (e.g. the return value of os.stat) more
3983 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003984

Georg Brandl3ee81df2008-05-17 18:14:43 +00003993- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3994 envvar and sys.dont_write_bytecode attribute. All these can be set
3995 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003996
Georg Brandl3ee81df2008-05-17 18:14:43 +00003997- Improve some exception messages when Windows fails to load an
3998 extension module. Now we get for example '%1 is not a valid Win32
3999 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004006- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004007 and INF. float("nan"), float("inf") and float("-inf") now work on
4008 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004010- Compiler now generates simpler and faster code for dictionary
4011 literals. The oparg for BUILD_MAP now indicates an estimated
4012 dictionary size. There is a new opcode, STORE_MAP, for adding
4013 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004042- Patch #1739468: Directories and zipfiles containing a __main__.py
4043 file can now be directly executed by passing their name to the
4044 interpreter. The directory/zipfile is automatically inserted as the
4045 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004047- Issue #1265: Fix a problem with sys.settrace, if the tracing
4048 function uses a generator expression when at the same time the
4049 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004050
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004051- sets and frozensets now have an isdisjoint() method.

4056
Georg Brandl21e99f42010-03-07 15:23:59 +00004057- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004058 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4059 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004060
Georg Brandl3ee81df2008-05-17 18:14:43 +00004061- Issue #1686386: Tuple's tp_repr did not take into account the
4062 possibility of having a self-referential tuple, which is possible
4063 from C code. Nor did object's tp_str consider that a type's tp_str
4064 could do something that could lead to an inifinite recursion.
4065 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4066 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004067
Georg Brandl3ee81df2008-05-17 18:14:43 +00004068- Issue #1164: It was possible to trigger deadlock when using the
4069 'print' statement to write to a file since the GIL was not released
4070 as needed. Now PyObject_Print() does the right thing along with
4071 various tp_print implementations of the built-in types and those in
4072 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004073
Georg Brandl3ee81df2008-05-17 18:14:43 +00004074- Issue #1147: Exceptions were directly allowing string exceptions in

4076 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00004080
Brett Cannon1e534b52007-09-07 04:18:30 +00004081- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004082 PyObject_Call() never calling back out to Python code to trigger
4083 recursion depth updates/checks. Required the creation of a static
4084 RuntimeError instance in case normalizing an exception put the
4085 recursion check value past its limit. Fixes crashers
4086 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004087

Neal Norwitz0ac60192007-05-27 04:08:54 +00004101- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004102 __*__ attributes. (Some already existed, e.g., __doc__ and
4103 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004104
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004105- Add -3 option to the interpreter to warn about features that are
4106 deprecated and will be changed/removed in Python 3.0.
4107
Georg Brandl2134e752007-05-21 20:34:16 +00004108- Patch #1686487: you can now pass any mapping after '**' in function
4109 calls.
4110
Collin Winter62903052007-05-18 23:11:24 +00004111- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112 "except E as target:". This is to provide forwards compatibility
4113 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004120- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004121 setting a plain string, ie don't expand to single letter identifiers.
4122
Raymond Hettinger13936692007-04-11 18:40:58 +00004123- Request #1191699: Slices can now be pickled.
4124
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004125- Request #1193128: str.translate() now allows a None argument for
4126 translations that only remove characters without re-mapping the
4127 remaining characters.
4128
Georg Brandl5cb76c12007-03-21 09:00:39 +00004129- Patch #1682205: a TypeError while unpacking an iterable is no longer

4133
Guido van Rossum143b5642007-03-23 04:58:42 +00004134- Bug #1683368: The object.__init__() and object.__new__() methods are
4135 now stricter in rejecting excess arguments. The only time when
4136 either allows excess arguments is when it is not overridden and the
4137 other one is. For backwards compatibility, when both are
4138 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004139 warning later). Also, type.__init__() insists on the same signature
4140 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004141
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4143 object to complex using its __complex__() method before falling back
4144 to the __float__() method. Therefore, the functions in the cmath
4145 module now can operate on objects that define a __complex__()
4146 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004147
Georg Brandl3ee81df2008-05-17 18:14:43 +00004148- Patch #1623563: allow __class__ assignment for classes with
4149 __slots__. The old and the new class are still required to have the
4150 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004151

4157 its type.

4163
Georg Brandl7b9c5552007-03-12 14:30:05 +00004164- Bug #1678647: write a newline after printing an exception in any
4165 case, even when converting the value to a string failed.
4166
Georg Brandl871f1bc2007-03-12 13:17:36 +00004167- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004168 its argument, if it exists. If not, it will work like before. This
4169 allows customizing the output of dir() in the presence of a
4170 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004172- Patch #922167: Python no longer segfaults when faced with infinitely
4173 self-recursive reload() calls (as reported by bug #742342).
4174
Georg Brandl3ee81df2008-05-17 18:14:43 +00004175- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Patch #1491866: change the complex() constructor to allow
4179 parthensized forms. This means complex(repr(x)) now works instead of
4180 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004181
Georg Brandlaa2321b2007-03-07 00:40:28 +00004182- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004183 makes the filenames the warning module prints much more sensible
4184 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004185

4187 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188 variable is given, but break into the interactive interpreter just
4189 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004197- Patch #1674228: when assigning a slice (old-style), check for the
4198 sq_ass_slice instead of the sq_slice slot.
4199
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- When printing an unraisable error, don't print exceptions. before
4201 the name. This duplicates the behavior whening normally printing
4202 exceptions.

Guido van Rossum8bc09652008-02-21 18:18:37 +00004344- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00004735 AttributeError instead of an IOError when the server's response
4736 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004737

Georg Brandl3ee81df2008-05-17 18:14:43 +00004753- Patch #1530482: add pydoc.render_doc() which returns the

4768
Georg Brandl92a6bae2007-03-13 17:43:32 +00004769- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004770 are set for invalid interpolation sequences that would lead to
4771 errors on reading back those values.

4825
Georg Brandl3ee81df2008-05-17 18:14:43 +00004826- unittest now verifies more of its assumptions. In particular,
4827 TestCase and TestSuite subclasses (not instances) are no longer
4828 accepted in TestSuite.addTest(). This should cause no
4829 incompatibility since it never made sense with ordinary subclasses
4830 -- the failure just occurred later, with a more cumbersome
4831 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005220 time so that opening a database previously created with the DB_DUP
5221 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5222 opens. Specifically: dictionary assignment to a DB object will
5223 replace all values for a given key when the database allows
5224 duplicate values. DB users should use DB.put(k, v) when they want
5225 to store duplicates; not DB[k] = v.

5234 behavior of quoting dots if they are the second character of any
5235 line.

5581 of w# format code incorrectly truncated the length to an int, even
5582 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5583 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005613- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5614 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
