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.

44-------
45
Mark Dickinson7c63eee2010-04-02 22:27:36 +000046- Issue #8294: The Fraction constructor now accepts Decimal and float
47 instances directly.
48
Mark Dickinsone096e822010-04-02 10:17:07 +000049- Issue #7279: Comparisons involving a Decimal signaling NaN now
50 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000051 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
52 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000053
Mark Dickinson99d80962010-04-02 08:53:22 +000054- Issue #2531: Comparison operations between floats and Decimal
55 instances now return a result based on the numeric values of the
56 operands; previously they returned an arbitrary result based on
57 the relative ordering of id(float) and id(Decimal).
58
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000059- Issue #8233: When run as a script, py_compile.py optionally takes a single
60 argument `-` which tells it to read files to compile from stdin. Each line
61 is read on demand and the named file is compiled immediately. (Original
62 patch by Piotr Ożarowski).
63
64- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
65 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000066
Florent Xicluna58b65662010-03-30 16:29:03 +000067- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
68 form feed (0x0C) are now considered linebreaks, as specified in Unicode
69 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +000070 http://www.unicode.org/reports/tr14/
71
Mark Dickinson9588d992010-03-27 11:14:37 +000072- Comparisons using one of <, <=, >, >= between a complex instance and
73 a Fractions instance now raise TypeError instead of returning
74 True/False. This makes Fraction <=> complex comparisons consistent with
75 int <=> complex, float <=> complex, and complex <=> complex comparisons.
76
Michael Foorde6410c52010-03-29 20:04:23 +000077- Addition of ``WeakSet`` to the ``weakref`` module.

82 running from the build directory (POSIX only).
83
Florent Xiclunae1f4c922010-03-22 22:45:50 +000084- Issue #7667: Fix doctest failures with non-ASCII paths.
85
Antoine Pitrou513d9ae2010-03-22 19:59:46 +000086- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
87 didn't support chflags() (for example ZFS under FreeBSD). The error is
88 now silenced.
89
Florent Xicluna9e7a4c92010-03-22 16:07:38 +000090- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
91 deprecated.
92
R. David Murrayc9d1a782010-03-22 15:55:09 +000093- Issue #7860: platform.uname now reports the correct 'machine' type
94 when Python is running in WOW64 mode on 64 bit Windows.
95
Vinay Sajip804899b2010-03-22 15:29:01 +000096- logging: Added getChild utility method to Logger and added isEnabledFor
97 method to LoggerAdapter.
98
Vinay Sajip31e928e2010-03-22 13:02:28 +000099- Issue #8201: logging: Handle situation of non-ASCII and Unicode
100 logger names existing at the same time, causing a Unicode error
101 when configuration code attempted to sort the existing loggers.
102
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000103- Issue #8200: logging: Handle errors when multiprocessing is not
104 fully loaded when logging occurs.
105
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000106- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
107 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
108 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000109
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000110- Issue #8179: Fix macpath.realpath() on a non-existing path.
111
Florent Xicluna2e0a53f2010-03-18 21:50:06 +0000112- Issue #8024: Update the Unicode database to 5.2.
113
Antoine Pitroud7b731d2010-03-17 22:45:39 +0000114- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support

122
Matthias Klose358e7ff2010-03-15 13:42:23 +0000123- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
124 the locale.
125
Georg Brandlba83f822010-03-14 09:50:54 +0000126- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000127 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000128 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000129
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000130- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000131 for ``TimedRotatingFileHandler`` by using the modification time of an
132 existing log file to compute the next rollover time. If the log file does
133 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000134

Florent Xicluna47627d52010-03-08 15:20:28 +0000141 classes.
142
Georg Brandlba83f822010-03-14 09:50:54 +0000143- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
144 a base64 transfer-encoded payload *after* decoding it; it no longer does.
145 This is a behavior change, so email's minor version number is now bumped, to
146 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000147

Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000162- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
163
Jesus Cea6557aac2010-03-22 14:22:26 +0000164- Issue #8156: bsddb module updated to version 4.8.4.
165 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
166 This update drops support for Berkeley DB 4.0, and adds support for 4.8.

Matthias Klose817acef2010-03-15 00:02:36 +0000168- Issue #8142: Update libffi to the 3.0.9 release.
169
Georg Brandlba83f822010-03-14 09:50:54 +0000170- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
171 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
172 argument's __int__ method to convert to an integer before packing. It also
173 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
174 was inconsistent: __int__ was used for some integer codes but not for others,
175 and the set of integer codes for which it was used differed between native
176 packing and standard packing.)

Antoine Pitrou76c86492010-04-01 16:42:11 +0000207- Issue #8276: PyEval_CallObject() is now only available in macro form. The
208 function declaration, which was kept for backwards compatibility reasons,
209 is now removed (the macro was introduced in 1997!).
210
Larry Hastings402b73f2010-03-25 00:54:54 +0000211- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000212 from Python 3.1. All existing Python CObjects in the main distribution
213 have been converted to capsules. To address backwards-compatibility
214 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

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

Antoine Pitroud840e512010-02-04 20:20:18 +0000452- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000453 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000454 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000459- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000460 file position when calling `truncate()`. It would previously change the file
461 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000462 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
463
Benjamin Petersone06f7112010-01-28 02:15:02 +0000464- UserDict is now a new-style class.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000481- Issue #7748: Since unicode values are supported for some metadata options in
482 Distutils, the DistributionMetadata get_* methods will now return an utf-8
483 encoded string for them. This ensures that the upload and register commands
484 send the correct values to PyPI without any error.

558Core and Builtins
559-----------------
560
Georg Brandlba83f822010-03-14 09:50:54 +0000561- The ``__complex__()`` method is now looked up on the class of instances to
562 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000564- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
565 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
566
Mark Dickinson1b34d252010-01-01 17:27:30 +0000567- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000568 DeprecationWarning when passed a float argument where an integer was expected.
569 These functions and methods now raise TypeError instead. The majority of the
570 effects of this change are in the extension modules, but some core functions
571 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
572 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000585- Issue #1811: Improve accuracy and cross-platform consistency for true division
586 of integers: the result of a/b is now correctly rounded for ints a and b (at
587 least on IEEE 754 platforms), and in particular does not depend on the
588 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +0000590- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

596
Georg Brandlba83f822010-03-14 09:50:54 +0000597 These executables now work properly with the arch(1) command: ``arch -ppc
598 python`` will start a universal binary version of python in PPC mode (unlike
599 previous releases).

739 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000740
Georg Brandlba83f822010-03-14 09:50:54 +0000741- Remove switch from "%f" formatting to "%g" formatting for floats larger than
742 1e50 in absolute value.

756 decimal string that's guaranteed to round back to x under correct rounding
757 (with round-half-to-even rounding mode). Previously it gave a string based on

759 similarly. On platforms where the correctly-rounded strtod and dtoa code is

Georg Brandlba83f822010-03-14 09:50:54 +0000762- Issue #7117: On almost all platforms: float-to-string and string-to-float
763 conversions within Python are now correctly rounded. Places these conversions
764 occur include: str for floats and complex numbers; the float and complex
765 constructors; old-style and new-style numeric formatting; serialization and
766 deserialization of floats and complex numbers using marshal, pickle and json;
767 parsing of float and imaginary literals in Python code; Decimal-to-float
768 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000769
Georg Brandlba83f822010-03-14 09:50:54 +0000770 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
771 providing correctly-rounded strtod and dtoa C functions. This code is
772 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
773 the C compiler. There may be a small number of platforms on which correct
774 operation of this code cannot be guaranteed, so the code is not used: notably,
775 this applies to platforms where the C double format is not IEEE 754 binary64,
776 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
777 and Python's configure script is unable to determine how to change the FPU
778 precision. On these platforms conversions use the platform strtod and dtoa,
779 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000781- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
782 uses the correctly-rounded string <-> float conversions described above (when
783 available), and so produces correctly rounded results that will display nicely
784 under the float repr. There are two related small changes: (1) round now
785 accepts any class with an ``__index__()`` method for its second argument (but
786 no longer accepts floats for the second argument), and (2) an excessively
787 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
788 raises an exception.

1167 this code path is really executed because I cannot move to such directory on

1194 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00002365 - Packing a float now always gives a Deprecation Warning. Previously it
2366 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00002368 - If x is not an int, long or float, then packing x will always result in
2369 struct.error. Previously an x with an __int__ method could be packed by
2370 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2371 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2372 neither __int__ nor __long__, TypeError used to be raised (with a
2373 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2374 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00002376 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
2377 argument with an __int__ method can be packed, but use of this feature
2378 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002571- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

2573 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2574 ``printf`` function, whereas PyString_FromFormat has an independent

2672 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2673 for catch_warnings() also led to an improvement in the raising of a
2674 DeprecationWarning related to warnings.warn_explicit().

2698
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002699- Issue #2975: When compiling several extension modules with Visual Studio 2008

2701 without limit.
2702
Benjamin Peterson37346b22008-08-23 20:27:43 +00002703- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002740What's New in Python 2.6 beta 3?
2741================================
2742
Barry Warsaw07a4a382008-08-21 01:15:08 +00002743*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002744
2745Core and Builtins
2746-----------------
2747
Guido van Rossumf8402962008-08-20 15:01:50 +00002748- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2749 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2750 extensions do not automatically benefit from the class attribute
2751 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2752 to their tp_flags field if they care. This is a backwards
2753 compatibility feature; in 3.0, all types will use the cache by
2754 default.
2755
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002756- Keyword arguments can now follow starred arguments. (``f(a, *args,
2757 keyword=23)`` is now valid syntax.)
2758
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002759- ctypes function pointers that are COM methods have a boolean True
2760 value again.
2761
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002762- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2763 by denying s# to parse objects that have a releasebuffer procedure,
2764 and introducing s*.
2765
Georg Brandl1e13ea92008-08-11 09:07:59 +00002766- Issue #3537: Fix an assertion failure when an empty but presized dict
2767 object was stored in the freelist.
2768
Mark Dickinsonb6467572008-08-04 21:30:09 +00002769- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2770 ValueError consistently across platforms.
2771
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002772- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2773 (64bit Unix, for example), unichr() would truncate its argument and return
2774 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2775
Neal Norwitze7d8be82008-07-31 17:17:14 +00002776- Apply security patches from Apple.
2777
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002778- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2779 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2780
Antoine Pitrou92f82162008-07-25 22:22:08 +00002781- Issue #1819: function calls with several named parameters are now on
2782 average 35% faster (as measured by pybench).
2783
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002784- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2785 the python debugger steps into a class statement: the free variables (local
2786 variables defined in an outer scope) would be deleted from the outer scope.
2787
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002788- Issue #2620: Overflow checking when allocating or reallocating memory
2789 was not always being done properly in some python types and extension
2790 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2791 all been updated to perform better checks and places in the code that
2792 would previously leak memory on the error path when such an allocation
2793 failed have been fixed.
2794

2796-------
2797

2799
Benjamin Petersone977ad42008-08-20 01:42:01 +00002800- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2801 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2802
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002803- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2804 version reported by these tools does not necessarily follow the python
2805 version numbering scheme, so the module is less strict when parsing it.
2806
Nick Coghlanf70385a2008-08-18 12:42:46 +00002807- Issue #2235: Added Py3k warnings for types which will become unhashable
2808 under the stricter __hash__ inheritance rules in 3.0. Several types
2809 which did not meet the rules for hash invariants and were already
2810 unhashable in 3.0 have now been explicitly flagged as unhashable in
2811 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2812 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2813
Brett Cannon88f801d2008-08-18 00:46:22 +00002814- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2822
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002823- Issue #3575: Incremental decoder's decode function now takes bytearray
2824 by using 's*' instead of 't#'.
2825
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002826- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002827 fails unicode conversion on 2nd parameter. (windows only)
2828
Facundo Batista94f243a2008-08-17 03:38:39 +00002829- Issue 2464. urllib2 now supports a malformation in the URL received
2830 in a redirect.
2831
Brett Cannonabe423e2008-08-16 21:47:07 +00002832- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002833 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002834
Facundo Batistaeb90b782008-08-16 14:44:07 +00002835- Issue #2776: fixed small issue when handling an URL with double slash
2836 after a 302 response in the case of not going through a proxy.
2837
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002838- Issue #2676: in the email package, content-type parsing was hanging on
2839 pathological input because of quadratic or exponential behaviour of a
2840 regular expression.
2841
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002842- Issue #3476: binary buffered reading through the new "io" library is now
2843 thread-safe.
2844
Brett Cannonbf3157b2008-08-14 05:00:03 +00002845- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2846 since mimetools itself is deprecated. Because modules are cached, all
2847 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2848
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002849- Issue #3134: shutil referenced undefined WindowsError symbol.
2850
Robert Schuppenies14646332008-08-10 11:01:53 +00002851- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2852 menu entries were not deleted.
2853
Brett Cannon83e81842008-08-09 23:30:55 +00002854- Copied the implementation of reduce() to _functools.reduce() to have a
2855 version that did not raise a DeprecationWarning under -3.
2856
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002857- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2858 a MemoryError rather than silently stop the iteration.
2859
Guido van Rossum59ce9012008-08-09 14:55:34 +00002860- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2861 to _sre.compile() will now be rejected. This should not affect anybody
2862 since the re.compile() function never generates invalid re-bytecode.
2863
Skip Montanaroa032bf42008-08-08 22:52:51 +00002864- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00002868- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2869 the reload() built-in has been removed.
2870
Brett Cannon7e30b672008-08-04 21:52:25 +00002871- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00002883 asking for a specific length. This problem only affected files opened
2884 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002885

2910 file name rather than a ZipInfo instance, so files are extracted with
2911 mode 0600 rather than 000 under Unix.
2912
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002913- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2931 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002934What's New in Python 2.6 beta 2?
2935================================
2936
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002937*Release date: 17-Jul-2008*
2938
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002939Core and Builtins
2940-----------------
2941
Georg Brandl3e483f62008-07-16 22:57:41 +00002942- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2943 its methods now allow for items objects that can be converted to
2944 an integer using operator.index().
2945
Mark Dickinson64b7e502008-07-16 09:40:03 +00002946- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2947 produced a ValueError instead of giving the correct float.
2948
Eric Smitha5fa5a22008-07-16 00:11:49 +00002949- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2950 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2951
Mark Dickinson7103aa42008-07-15 19:08:33 +00002952- Issue #3008: the float type has a new instance method 'float.hex'
2953 and a new class method 'float.fromhex' to convert floating-point
2954 numbers to and from hexadecimal strings, respectively.
2955
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002956- Issue #2235: __hash__ is once again inherited by default. To allow
2957 collections.Hashable to remain meaningful in the presence of the
2958 default hash implementation (object.__hash__), it is now possible
2959 to explicit block inheritance of hash by setting __hash__=None at
2960 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2961 level.
2962
Nick Coghlanb028f502008-07-13 14:52:36 +00002963- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2964 the parent module cannot be found while performing an absolute import.
2965 This means that an incorrectly defined __package__ attribute will
2966 now only prevent relative imports in that module rather than causing
2967 all imports from that module to fail.
2968
Nick Coghlan14ff9942008-07-08 14:21:42 +00002969- Issue #2517: Allow unicode messages in Exceptions again by correctly
2970 bypassing the instance dictionary when looking up __unicode__ on
2971 new-style classes.
2972
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002973- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2974 set to a custom object whose write() method happens to install
2975 another file in sys.stdout.
2976
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002977- Issue #3088: Corrected a race condition in classes derived from
2978 threading.local: the first member set by a thread could be saved in
2979 another thread's dictionary.
2980
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002981- Issue #3004: Minor change to slice.indices(): the start and stop
2982 arguments are now treated identically, making the behaviour easier
2983 to describe and understand. For example, slice(None, -10,
2984 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2985 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2986 10, -1).
2987
Georg Brandl278fc502008-07-19 12:46:12 +00002988- Issue #3219: Calling a function with repeated keyword arguments,
2989 f(a=2, a=23), would not cause a syntax error. This was a regression
2990 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002991
Georg Brandl278fc502008-07-19 12:46:12 +00002992- Issue #2862: Make int and float freelist management consistent with
2993 other freelists. Changes their CompactFreeList apis into
2994 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002995
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002996Library
2997-------
2998
Thomas Heller57adf222008-08-14 19:10:48 +00002999- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3000 api functions without holding the GIL, which could lead to a fatal
3001 error when they failed.
3002
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003003- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
3004

3010
Jesse Noller13e9d582008-07-16 14:32:36 +00003011- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3012 ForkingPickler.register() to resolve conflict with ctypes.
3013
Vinay Sajip51e65192008-07-18 09:01:10 +00003014- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003015
Thomas Heller880f5292008-07-15 19:39:38 +00003016- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3017 a valid dlerror() message.
3018
Thomas Heller2bad6572008-07-15 17:19:50 +00003019- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3020 incomplete structure was created.
3021

3025
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003026- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003027
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003028- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3029 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003030 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003031 content-length. The problem had been corrected in the 2.4 branch, but never
3032 merged into trunk.
3033
Georg Brandle78fbcc2008-07-05 10:13:36 +00003034- Issue #2663: add filtering capability to shutil.copytree().

3037
3038- Issue #1526: Allow more than 64k files to be added to Zip64 file.
3039
3040- Issue #1746: Correct handling of zipfile archive comments (previously
3041 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00003042 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00003043
Vinay Sajip51e65192008-07-18 09:01:10 +00003044- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003045 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003046
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003047- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3048 handling is now the same as that of other special attributes like __name__).
3049
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003050- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3051 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003502- Issue #1631171: Re-implement the 'warnings' module in C (the
3503 original Python code has been kept as backup). This will allow for
3504 using the 'warning's machinery in such places as the parser where
3505 use of pure Python code is not possible. Both the ``showarning()``
3506 and ``formatwarning()`` gain an optional 'line' argument which is
3507 not called by default for backwards-compatibility reasons. Setting
3508 ``warnings.showwarning()`` to an implementation that lacks support
3509 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003572- Issue #2550: The approach used by client/server code for obtaining
3573 ports to listen on in network-oriented tests has been refined in an
3574 effort to facilitate running multiple instances of the entire
3575 regression test suite in parallel without issue.
3576 test_support.bind_port() has been fixed such that it will always
3577 return a unique port -- which wasn't always the case with the
3578 previous implementation, especially if socket options had been set
3579 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3580 new implementation of bind_port() will actually raise an exception
3581 if it is passed an AF_INET/SOCK_STREAM socket with either the
3582 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3583 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3584 the socket it's been passed. This currently only applies to
3585 Windows. This option prevents any other sockets from binding to the
3586 host/port we've bound to, thus removing the possibility of the
3587 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3588 when a second SOCK_STREAM socket binds and accepts to a host/port
3589 that's already been bound by another socket. The optional preferred
3590 port parameter to bind_port() has been removed. Under no
3591 circumstances should tests be hard coding ports!
3592
3593 test_support.find_unused_port() has also been introduced, which will
3594 pass a temporary socket object to bind_port() in order to obtain an
3595 unused port. The temporary socket object is then closed and
3596 deleted, and the port is returned. This method should only be used
3597 for obtaining an unused port in order to pass to an external program
3598 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3599 a parameter to a server-oriented class that doesn't give you direct
3600 access to the underlying socket used.
3601
3602 Finally, test_support.HOST has been introduced, which should be used
3603 for the host argument of any relevant socket calls (i.e. bind and
3604 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003605
3606 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003607 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003608 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3609 test_asynchat and test_socket_ssl.
3610
Georg Brandl3ee81df2008-05-17 18:14:43 +00003611 It is now possible for multiple instances of the regression test
3612 suite to run in parallel without issue.

3768 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00003769 platform.machine() and platform.processor() will report this
3770 information as well.

3880
Fred Drakea8ee94b2008-03-01 02:45:07 +00003881- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003882 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003887
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003888- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003889 issue 215555 for a discussion.
3890
Eric Smitha73fbe72008-02-23 03:09:44 +00003891- Added the future_builtins module, which contains hex() and oct().
3892 These are the PEP 3127 version of these functions, designed to be
3893 compatible with the hex() and oct() builtins from Python 3.0. They
3894 differ slightly in their output formats from the existing, unchanged
3895 Python 2.6 builtins. The expected usage of the future_builtins
3896 module is:
3897 from future_builtins import hex, oct
3898
Eric Smith7ef40bf2008-02-20 23:34:22 +00003899- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3900 exponents for exponents with absolute value < 100. Follows C99
3901 standard. This is a change on Windows, which would use 3 digits.
3902 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3903 so that any alterations it does to the resulting string will be
3904 available in stringlib/formatter.h (for float.__format__).
3905
Eric Smith5a3c1352008-02-19 13:21:56 +00003906- Implemented PEP 3101, Advanced String Formatting. This adds a new
3907 builtin format(); a format() method for str and unicode; a
3908 __format__() method to object, str, unicode, int, long, float, and
3909 datetime; the class string.Formatter; and the C API
3910 PyObject_Format().
3911
Georg Brandl3ee81df2008-05-17 18:14:43 +00003912- Fixed several potential crashes, all caused by specially crafted
3913 __del__ methods exploiting objects in temporarily inconsistent
3914 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003915
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003916- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003917 prevent a possible crash: an Abstract Base Class would try to access
3918 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003919

Georg Brandl3ee81df2008-05-17 18:14:43 +00003923- Clear all free lists during a gc.collect() of the highest generation
3924 in order to allow pymalloc to free more arenas. Python may give back
3925 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003926
Georg Brandl3ee81df2008-05-17 18:14:43 +00003927- Issue #2045: Fix an infinite recursion triggered when printing a
3928 subclass of collections.defaultdict, if its default_factory is set
3929 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003930
Christian Heimesf75dbef2008-02-08 00:11:31 +00003931- Fixed a minor memory leak in dictobject.c. The content of the free
3932 list was not freed on interpreter shutdown.
3933
Georg Brandl21e99f42010-03-07 15:23:59 +00003934- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003935 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003936
Georg Brandl3ee81df2008-05-17 18:14:43 +00003937- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3938 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003939 to compact the internal free lists of pre-allocted ints and floats.
3940
Georg Brandl3ee81df2008-05-17 18:14:43 +00003941- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3942 calls. Python expected the return type int but the fork familie
3943 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003944
Georg Brandl3ee81df2008-05-17 18:14:43 +00003945- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3955 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003956
Georg Brandl3ee81df2008-05-17 18:14:43 +00003957- Patch #1473257: generator objects gain a gi_code attribute. This is
3958 the same object as the func_code attribute of the function that
3959 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003960
Georg Brandl3ee81df2008-05-17 18:14:43 +00003961- Issue #1920: "while 0" statements were completely removed by the
3962 compiler, even in the presence of an "else" clause, which is
3963 supposed to be run when the condition is false. Now the compiler
3964 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003965
Guido van Rossumeead05f2008-01-24 18:21:02 +00003966- A few crashers fixed: weakref_in_del.py (issue #1377858);
3967 loosing_dict_ref.py (issue #1303614, test67.py);
3968 borrowed_ref_[34].py (not in tracker).
3969
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003970- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003971 suppressed while an extension is loaded by calling SetErrorMode in
3972 dynload_win.c. The error is still reported properly.
3973
Georg Brandl3ee81df2008-05-17 18:14:43 +00003974- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003975 several extension methods and modules do not work without unicode
3976 support.
3977
Georg Brandl26543b12008-01-21 18:36:51 +00003978- Issue #1882: when compiling code from a string, encoding cookies in the
3979 second line of code were not always recognized correctly.
3980
Georg Brandl14404b62008-01-19 19:27:05 +00003981- Issue #1679: "0x" was taken as a valid integer literal.
3982
Georg Brandl6caad7d2008-01-26 14:19:22 +00003983- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003984 added.
3985
Christian Heimesc94e2b52008-01-14 04:13:37 +00003986- sys.float_info / PyFloat_GetInfo: The floating point information
3987 object was converted from a dict to a specialized structseq object.
3988
Georg Brandl3ee81df2008-05-17 18:14:43 +00003989- Patch #1816: Added sys.flags structseq. It exposes the status of
3990 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003991
Georg Brandl3ee81df2008-05-17 18:14:43 +00003992- Objects/structseq.c: Implemented new structseq representation. The
3993 patch makes structseqs (e.g. the return value of os.stat) more
3994 readable.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004004- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4005 envvar and sys.dont_write_bytecode attribute. All these can be set
4006 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004007
Georg Brandl3ee81df2008-05-17 18:14:43 +00004008- Improve some exception messages when Windows fails to load an
4009 extension module. Now we get for example '%1 is not a valid Win32
4010 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004017- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004018 and INF. float("nan"), float("inf") and float("-inf") now work on
4019 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004021- Compiler now generates simpler and faster code for dictionary
4022 literals. The oparg for BUILD_MAP now indicates an estimated
4023 dictionary size. There is a new opcode, STORE_MAP, for adding
4024 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004053- Patch #1739468: Directories and zipfiles containing a __main__.py
4054 file can now be directly executed by passing their name to the
4055 interpreter. The directory/zipfile is automatically inserted as the
4056 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004058- Issue #1265: Fix a problem with sys.settrace, if the tracing
4059 function uses a generator expression when at the same time the
4060 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004061
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004062- sets and frozensets now have an isdisjoint() method.

4067
Georg Brandl21e99f42010-03-07 15:23:59 +00004068- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004069 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4070 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004071
Georg Brandl3ee81df2008-05-17 18:14:43 +00004072- Issue #1686386: Tuple's tp_repr did not take into account the
4073 possibility of having a self-referential tuple, which is possible
4074 from C code. Nor did object's tp_str consider that a type's tp_str
4075 could do something that could lead to an inifinite recursion.
4076 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4077 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004078
Georg Brandl3ee81df2008-05-17 18:14:43 +00004079- Issue #1164: It was possible to trigger deadlock when using the
4080 'print' statement to write to a file since the GIL was not released
4081 as needed. Now PyObject_Print() does the right thing along with
4082 various tp_print implementations of the built-in types and those in
4083 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004084
Georg Brandl3ee81df2008-05-17 18:14:43 +00004085- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00004091
Brett Cannon1e534b52007-09-07 04:18:30 +00004092- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004093 PyObject_Call() never calling back out to Python code to trigger
4094 recursion depth updates/checks. Required the creation of a static
4095 RuntimeError instance in case normalizing an exception put the
4096 recursion check value past its limit. Fixes crashers
4097 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004098

Neal Norwitz0ac60192007-05-27 04:08:54 +00004112- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004113 __*__ attributes. (Some already existed, e.g., __doc__ and
4114 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004115
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004116- Add -3 option to the interpreter to warn about features that are
4117 deprecated and will be changed/removed in Python 3.0.
4118
Georg Brandl2134e752007-05-21 20:34:16 +00004119- Patch #1686487: you can now pass any mapping after '**' in function
4120 calls.
4121
Collin Winter62903052007-05-18 23:11:24 +00004122- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123 "except E as target:". This is to provide forwards compatibility
4124 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004131- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004132 setting a plain string, ie don't expand to single letter identifiers.
4133
Raymond Hettinger13936692007-04-11 18:40:58 +00004134- Request #1191699: Slices can now be pickled.
4135
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004136- Request #1193128: str.translate() now allows a None argument for
4137 translations that only remove characters without re-mapping the
4138 remaining characters.
4139
Georg Brandl5cb76c12007-03-21 09:00:39 +00004140- Patch #1682205: a TypeError while unpacking an iterable is no longer

4144
Guido van Rossum143b5642007-03-23 04:58:42 +00004145- Bug #1683368: The object.__init__() and object.__new__() methods are
4146 now stricter in rejecting excess arguments. The only time when
4147 either allows excess arguments is when it is not overridden and the
4148 other one is. For backwards compatibility, when both are
4149 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004150 warning later). Also, type.__init__() insists on the same signature
4151 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004152
Georg Brandl3ee81df2008-05-17 18:14:43 +00004153- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4154 object to complex using its __complex__() method before falling back
4155 to the __float__() method. Therefore, the functions in the cmath
4156 module now can operate on objects that define a __complex__()
4157 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Patch #1623563: allow __class__ assignment for classes with
4160 __slots__. The old and the new class are still required to have the
4161 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004162

4168 its type.

4174
Georg Brandl7b9c5552007-03-12 14:30:05 +00004175- Bug #1678647: write a newline after printing an exception in any
4176 case, even when converting the value to a string failed.
4177
Georg Brandl871f1bc2007-03-12 13:17:36 +00004178- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004179 its argument, if it exists. If not, it will work like before. This
4180 allows customizing the output of dir() in the presence of a
4181 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004183- Patch #922167: Python no longer segfaults when faced with infinitely
4184 self-recursive reload() calls (as reported by bug #742342).
4185
Georg Brandl3ee81df2008-05-17 18:14:43 +00004186- Patch #1675981: remove unreachable code from ``type.__new__()``

4190 parthensized forms. This means complex(repr(x)) now works instead of
4191 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004192
Georg Brandlaa2321b2007-03-07 00:40:28 +00004193- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004194 makes the filenames the warning module prints much more sensible
4195 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004196

4198 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004199 variable is given, but break into the interactive interpreter just
4200 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004208- Patch #1674228: when assigning a slice (old-style), check for the
4209 sq_ass_slice instead of the sq_slice slot.
4210
Georg Brandl3ee81df2008-05-17 18:14:43 +00004211- When printing an unraisable error, don't print exceptions. before
4212 the name. This duplicates the behavior whening normally printing
4213 exceptions.

Guido van Rossum8bc09652008-02-21 18:18:37 +00004355- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00004746 AttributeError instead of an IOError when the server's response
4747 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004748

Georg Brandl3ee81df2008-05-17 18:14:43 +00004764- Patch #1530482: add pydoc.render_doc() which returns the

4779
Georg Brandl92a6bae2007-03-13 17:43:32 +00004780- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004781 are set for invalid interpolation sequences that would lead to
4782 errors on reading back those values.

4836
Georg Brandl3ee81df2008-05-17 18:14:43 +00004837- unittest now verifies more of its assumptions. In particular,
4838 TestCase and TestSuite subclasses (not instances) are no longer
4839 accepted in TestSuite.addTest(). This should cause no
4840 incompatibility since it never made sense with ordinary subclasses
4841 -- the failure just occurred later, with a more cumbersome
4842 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005231 time so that opening a database previously created with the DB_DUP
5232 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5233 opens. Specifically: dictionary assignment to a DB object will
5234 replace all values for a given key when the database allows
5235 duplicate values. DB users should use DB.put(k, v) when they want
5236 to store duplicates; not DB[k] = v.

5245 behavior of quoting dots if they are the second character of any
5246 line.

5592 of w# format code incorrectly truncated the length to an int, even
5593 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5594 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005624- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5625 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
