Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00007What's New in Python 2.7 beta 1?
8================================

12Core and Builtins
13-----------------
14
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000015- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
16
Eric Smithd44b2fc2010-04-02 12:30:56 +000017- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
18 is called with a non-empty format string. This is an effort to
19 future-proof user code. If a derived class does not currently
20 implement __format__ but later adds its own __format__, it would
21 most likely break user code that had supplied a format string. This
22 will be changed to a DeprecationWaring in Python 3.3 and it will be
23 an error in Python 3.4.
24
Antoine Pitroua57df2c2010-03-31 21:32:15 +000025- Issue #8268: Old-style classes (not just instances) now support weak
26 references.
27
Victor Stinner6cbf90f2010-03-25 00:21:53 +000028- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
29 optimizations are disabled when --with-pydebug is used.
30
Victor Stinnerc7790ed2010-03-22 12:36:28 +000031- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000032
Benjamin Peterson96545892010-03-21 20:21:00 +000033- Issue #6474: Make error message from passing an inadequate number of keyword
34 arguments to a function correct.
35
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000036- Issue #8164: Don't allow lambda functions to have a docstring.
37
Victor Stinner66644262010-03-10 22:30:19 +000038- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000039 (SIGINT). If an error occurs while importing the site module, the error is
40 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000041 module.
42
Collin Winter001a3952010-03-18 21:54:01 +000043- Code objects now support weak references.

46-------
47
Mark Dickinson7c63eee2010-04-02 22:27:36 +000048- Issue #8294: The Fraction constructor now accepts Decimal and float
49 instances directly.
50
Mark Dickinsone096e822010-04-02 10:17:07 +000051- Issue #7279: Comparisons involving a Decimal signaling NaN now
52 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000053 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
54 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000055
Mark Dickinson99d80962010-04-02 08:53:22 +000056- Issue #2531: Comparison operations between floats and Decimal
57 instances now return a result based on the numeric values of the
58 operands; previously they returned an arbitrary result based on
59 the relative ordering of id(float) and id(Decimal).
60
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000061- Issue #8233: When run as a script, py_compile.py optionally takes a single
62 argument `-` which tells it to read files to compile from stdin. Each line
63 is read on demand and the named file is compiled immediately. (Original
64 patch by Piotr Ożarowski).
65
66- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
67 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000068
Florent Xicluna58b65662010-03-30 16:29:03 +000069- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
70 form feed (0x0C) are now considered linebreaks, as specified in Unicode
71 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +000072 http://www.unicode.org/reports/tr14/
73
Mark Dickinson9588d992010-03-27 11:14:37 +000074- Comparisons using one of <, <=, >, >= between a complex instance and
75 a Fractions instance now raise TypeError instead of returning
76 True/False. This makes Fraction <=> complex comparisons consistent with
77 int <=> complex, float <=> complex, and complex <=> complex comparisons.
78
Michael Foorde6410c52010-03-29 20:04:23 +000079- Addition of ``WeakSet`` to the ``weakref`` module.
80

84 running from the build directory (POSIX only).
85
Florent Xiclunae1f4c922010-03-22 22:45:50 +000086- Issue #7667: Fix doctest failures with non-ASCII paths.
87
Antoine Pitrou513d9ae2010-03-22 19:59:46 +000088- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
89 didn't support chflags() (for example ZFS under FreeBSD). The error is
90 now silenced.
91
Florent Xicluna9e7a4c92010-03-22 16:07:38 +000092- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
93 deprecated.
94
R. David Murrayc9d1a782010-03-22 15:55:09 +000095- Issue #7860: platform.uname now reports the correct 'machine' type
96 when Python is running in WOW64 mode on 64 bit Windows.
97
Vinay Sajip804899b2010-03-22 15:29:01 +000098- logging: Added getChild utility method to Logger and added isEnabledFor
99 method to LoggerAdapter.
100
Vinay Sajip31e928e2010-03-22 13:02:28 +0000101- Issue #8201: logging: Handle situation of non-ASCII and Unicode
102 logger names existing at the same time, causing a Unicode error
103 when configuration code attempted to sort the existing loggers.
104
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000105- Issue #8200: logging: Handle errors when multiprocessing is not
106 fully loaded when logging occurs.
107
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000108- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
109 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
110 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000111
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000112- Issue #8179: Fix macpath.realpath() on a non-existing path.
113
Florent Xicluna2e0a53f2010-03-18 21:50:06 +0000114- Issue #8024: Update the Unicode database to 5.2.
115
Antoine Pitroud7b731d2010-03-17 22:45:39 +0000116- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support

124
Matthias Klose358e7ff2010-03-15 13:42:23 +0000125- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
126 the locale.
127
Georg Brandlba83f822010-03-14 09:50:54 +0000128- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000129 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000130 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000131
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000132- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000133 for ``TimedRotatingFileHandler`` by using the modification time of an
134 existing log file to compute the next rollover time. If the log file does
135 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000136

Florent Xicluna47627d52010-03-08 15:20:28 +0000143 classes.
144
Georg Brandlba83f822010-03-14 09:50:54 +0000145- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
146 a base64 transfer-encoded payload *after* decoding it; it no longer does.
147 This is a behavior change, so email's minor version number is now bumped, to
148 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000149

Matthias Klose817acef2010-03-15 00:02:36 +0000170- Issue #8142: Update libffi to the 3.0.9 release.
171
Georg Brandlba83f822010-03-14 09:50:54 +0000172- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
173 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
174 argument's __int__ method to convert to an integer before packing. It also
175 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
176 was inconsistent: __int__ was used for some integer codes but not for others,
177 and the set of integer codes for which it was used differed between native
178 packing and standard packing.)

Antoine Pitrou76c86492010-04-01 16:42:11 +0000209- Issue #8276: PyEval_CallObject() is now only available in macro form. The
210 function declaration, which was kept for backwards compatibility reasons,
211 is now removed (the macro was introduced in 1997!).
212
Larry Hastings402b73f2010-03-25 00:54:54 +0000213- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000214 from Python 3.1. All existing Python CObjects in the main distribution
215 have been converted to capsules. To address backwards-compatibility
216 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

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

Antoine Pitroud840e512010-02-04 20:20:18 +0000454- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000455 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000456 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000461- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000462 file position when calling `truncate()`. It would previously change the file
463 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000464 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000483- Issue #7748: Since unicode values are supported for some metadata options in
484 Distutils, the DistributionMetadata get_* methods will now return an utf-8
485 encoded string for them. This ensures that the upload and register commands
486 send the correct values to PyPI without any error.

560Core and Builtins
561-----------------
562
Georg Brandlba83f822010-03-14 09:50:54 +0000563- The ``__complex__()`` method is now looked up on the class of instances to
564 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000565
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000566- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
567 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
568
Mark Dickinson1b34d252010-01-01 17:27:30 +0000569- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000570 DeprecationWarning when passed a float argument where an integer was expected.
571 These functions and methods now raise TypeError instead. The majority of the
572 effects of this change are in the extension modules, but some core functions
573 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
574 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000587- Issue #1811: Improve accuracy and cross-platform consistency for true division
588 of integers: the result of a/b is now correctly rounded for ints a and b (at
589 least on IEEE 754 platforms), and in particular does not depend on the
590 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +0000592- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
593 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
594 in the subclass.

598
Georg Brandlba83f822010-03-14 09:50:54 +0000599 These executables now work properly with the arch(1) command: ``arch -ppc
600 python`` will start a universal binary version of python in PPC mode (unlike
601 previous releases).

662 the same as passing no argument.
663

Georg Brandlba83f822010-03-14 09:50:54 +0000739- Issue #3382: 'F' formatting for float and complex now convert the result to
740 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
741 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000742
Georg Brandlba83f822010-03-14 09:50:54 +0000743- Remove switch from "%f" formatting to "%g" formatting for floats larger than
744 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000745
Georg Brandlba83f822010-03-14 09:50:54 +0000746- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

Georg Brandlba83f822010-03-14 09:50:54 +0000757- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
758 decimal string that's guaranteed to round back to x under correct rounding
759 (with round-half-to-even rounding mode). Previously it gave a string based on
760 rounding x to 17 decimal digits. repr(x) for a complex number behaves
761 similarly. On platforms where the correctly-rounded strtod and dtoa code is
762 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +0000764- Issue #7117: On almost all platforms: float-to-string and string-to-float
765 conversions within Python are now correctly rounded. Places these conversions
766 occur include: str for floats and complex numbers; the float and complex
767 constructors; old-style and new-style numeric formatting; serialization and
768 deserialization of floats and complex numbers using marshal, pickle and json;
769 parsing of float and imaginary literals in Python code; Decimal-to-float
770 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000771
Georg Brandlba83f822010-03-14 09:50:54 +0000772 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
773 providing correctly-rounded strtod and dtoa C functions. This code is
774 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
775 the C compiler. There may be a small number of platforms on which correct
776 operation of this code cannot be guaranteed, so the code is not used: notably,
777 this applies to platforms where the C double format is not IEEE 754 binary64,
778 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
779 and Python's configure script is unable to determine how to change the FPU
780 precision. On these platforms conversions use the platform strtod and dtoa,
781 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000783- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
784 uses the correctly-rounded string <-> float conversions described above (when
785 available), and so produces correctly rounded results that will display nicely
786 under the float repr. There are two related small changes: (1) round now
787 accepts any class with an ``__index__()`` method for its second argument (but
788 no longer accepts floats for the second argument), and (2) an excessively
789 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
790 raises an exception.

1140
Georg Brandlba83f822010-03-14 09:50:54 +00001141- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on

1169 this code path is really executed because I cannot move to such directory on

1196 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00002367 - Packing a float now always gives a Deprecation Warning. Previously it
2368 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00002370 - If x is not an int, long or float, then packing x will always result in
2371 struct.error. Previously an x with an __int__ method could be packed by
2372 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2373 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2374 neither __int__ nor __long__, TypeError used to be raised (with a
2375 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2376 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00002378 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
2379 argument with an __int__ method can be packed, but use of this feature
2380 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002573- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

2575 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2576 ``printf`` function, whereas PyString_FromFormat has an independent
2577 implementation and uses "%zd" on all platforms for size_t values.
2578 This makes a difference on win64, where ``printf`` needs "%Id" to display

2674 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2675 for catch_warnings() also led to an improvement in the raising of a
2676 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002742What's New in Python 2.6 beta 3?
2743================================
2744
Barry Warsaw07a4a382008-08-21 01:15:08 +00002745*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002746
2747Core and Builtins
2748-----------------
2749
Guido van Rossumf8402962008-08-20 15:01:50 +00002750- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2751 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2752 extensions do not automatically benefit from the class attribute
2753 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2754 to their tp_flags field if they care. This is a backwards
2755 compatibility feature; in 3.0, all types will use the cache by
2756 default.
2757
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002758- Keyword arguments can now follow starred arguments. (``f(a, *args,
2759 keyword=23)`` is now valid syntax.)
2760
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002761- ctypes function pointers that are COM methods have a boolean True
2762 value again.
2763
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002764- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2765 by denying s# to parse objects that have a releasebuffer procedure,
2766 and introducing s*.
2767
Georg Brandl1e13ea92008-08-11 09:07:59 +00002768- Issue #3537: Fix an assertion failure when an empty but presized dict
2769 object was stored in the freelist.
2770
Mark Dickinsonb6467572008-08-04 21:30:09 +00002771- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2772 ValueError consistently across platforms.
2773
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002774- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2775 (64bit Unix, for example), unichr() would truncate its argument and return
2776 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2777
Neal Norwitze7d8be82008-07-31 17:17:14 +00002778- Apply security patches from Apple.
2779
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002780- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2781 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2782
Antoine Pitrou92f82162008-07-25 22:22:08 +00002783- Issue #1819: function calls with several named parameters are now on
2784 average 35% faster (as measured by pybench).
2785
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002786- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2787 the python debugger steps into a class statement: the free variables (local
2788 variables defined in an outer scope) would be deleted from the outer scope.
2789
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002790- Issue #2620: Overflow checking when allocating or reallocating memory
2791 was not always being done properly in some python types and extension
2792 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2793 all been updated to perform better checks and places in the code that
2794 would previously leak memory on the error path when such an allocation
2795 failed have been fixed.

2801
Benjamin Petersone977ad42008-08-20 01:42:01 +00002802- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2803 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2804
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002805- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2806 version reported by these tools does not necessarily follow the python
2807 version numbering scheme, so the module is less strict when parsing it.
2808
Nick Coghlanf70385a2008-08-18 12:42:46 +00002809- Issue #2235: Added Py3k warnings for types which will become unhashable
2810 under the stricter __hash__ inheritance rules in 3.0. Several types
2811 which did not meet the rules for hash invariants and were already
2812 unhashable in 3.0 have now been explicitly flagged as unhashable in
2813 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2814 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2815
Brett Cannon88f801d2008-08-18 00:46:22 +00002816- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2824
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002825- Issue #3575: Incremental decoder's decode function now takes bytearray
2826 by using 's*' instead of 't#'.
2827
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002828- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002829 fails unicode conversion on 2nd parameter. (windows only)
2830
Facundo Batista94f243a2008-08-17 03:38:39 +00002831- Issue 2464. urllib2 now supports a malformation in the URL received
2832 in a redirect.

Brett Cannonabe423e2008-08-16 21:47:07 +00002836
Facundo Batistaeb90b782008-08-16 14:44:07 +00002837- Issue #2776: fixed small issue when handling an URL with double slash
2838 after a 302 response in the case of not going through a proxy.
2839
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002840- Issue #2676: in the email package, content-type parsing was hanging on
2841 pathological input because of quadratic or exponential behaviour of a
2842 regular expression.
2843
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002844- Issue #3476: binary buffered reading through the new "io" library is now
2845 thread-safe.
2846
Brett Cannonbf3157b2008-08-14 05:00:03 +00002847- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2848 since mimetools itself is deprecated. Because modules are cached, all
2849 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2850
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002851- Issue #3134: shutil referenced undefined WindowsError symbol.
2852
Robert Schuppenies14646332008-08-10 11:01:53 +00002853- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2854 menu entries were not deleted.
2855
Brett Cannon83e81842008-08-09 23:30:55 +00002856- Copied the implementation of reduce() to _functools.reduce() to have a
2857 version that did not raise a DeprecationWarning under -3.
2858
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002859- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2860 a MemoryError rather than silently stop the iteration.
2861
Guido van Rossum59ce9012008-08-09 14:55:34 +00002862- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2863 to _sre.compile() will now be rejected. This should not affect anybody
2864 since the re.compile() function never generates invalid re-bytecode.
2865
Skip Montanaroa032bf42008-08-08 22:52:51 +00002866- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00002885 asking for a specific length. This problem only affected files opened
2886 using the new "io" module, not the built-in open() function.

2913 mode 0600 rather than 000 under Unix.
2914
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002915- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2933 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002936What's New in Python 2.6 beta 2?
2937================================
2938
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002939*Release date: 17-Jul-2008*
2940
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002941Core and Builtins
2942-----------------
2943
Georg Brandl3e483f62008-07-16 22:57:41 +00002944- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2945 its methods now allow for items objects that can be converted to
2946 an integer using operator.index().
2947
Mark Dickinson64b7e502008-07-16 09:40:03 +00002948- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2949 produced a ValueError instead of giving the correct float.
2950
Eric Smitha5fa5a22008-07-16 00:11:49 +00002951- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2952 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2953
Mark Dickinson7103aa42008-07-15 19:08:33 +00002954- Issue #3008: the float type has a new instance method 'float.hex'
2955 and a new class method 'float.fromhex' to convert floating-point
2956 numbers to and from hexadecimal strings, respectively.
2957
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002958- Issue #2235: __hash__ is once again inherited by default. To allow
2959 collections.Hashable to remain meaningful in the presence of the
2960 default hash implementation (object.__hash__), it is now possible
2961 to explicit block inheritance of hash by setting __hash__=None at
2962 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2963 level.
2964
Nick Coghlanb028f502008-07-13 14:52:36 +00002965- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2966 the parent module cannot be found while performing an absolute import.
2967 This means that an incorrectly defined __package__ attribute will
2968 now only prevent relative imports in that module rather than causing
2969 all imports from that module to fail.
2970
Nick Coghlan14ff9942008-07-08 14:21:42 +00002971- Issue #2517: Allow unicode messages in Exceptions again by correctly
2972 bypassing the instance dictionary when looking up __unicode__ on
2973 new-style classes.
2974
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002975- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2976 set to a custom object whose write() method happens to install
2977 another file in sys.stdout.
2978
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002979- Issue #3088: Corrected a race condition in classes derived from
2980 threading.local: the first member set by a thread could be saved in
2981 another thread's dictionary.
2982
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002983- Issue #3004: Minor change to slice.indices(): the start and stop
2984 arguments are now treated identically, making the behaviour easier
2985 to describe and understand. For example, slice(None, -10,
2986 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2987 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2988 10, -1).
2989
Georg Brandl278fc502008-07-19 12:46:12 +00002990- Issue #3219: Calling a function with repeated keyword arguments,
2991 f(a=2, a=23), would not cause a syntax error. This was a regression
2992 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002993
Georg Brandl278fc502008-07-19 12:46:12 +00002994- Issue #2862: Make int and float freelist management consistent with
2995 other freelists. Changes their CompactFreeList apis into
2996 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002997

2999-------
3000
Thomas Heller57adf222008-08-14 19:10:48 +00003001- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3002 api functions without holding the GIL, which could lead to a fatal
3003 error when they failed.
3004
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003005- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
3006

3012
Jesse Noller13e9d582008-07-16 14:32:36 +00003013- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3014 ForkingPickler.register() to resolve conflict with ctypes.
3015
Vinay Sajip51e65192008-07-18 09:01:10 +00003016- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003017
Thomas Heller880f5292008-07-15 19:39:38 +00003018- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3019 a valid dlerror() message.
3020
Thomas Heller2bad6572008-07-15 17:19:50 +00003021- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3022 incomplete structure was created.
3023

3027
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003028- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003029
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003030- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3031 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003032 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003033 content-length. The problem had been corrected in the 2.4 branch, but never
3034 merged into trunk.
3035
Georg Brandle78fbcc2008-07-05 10:13:36 +00003036- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00003044 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00003045
Vinay Sajip51e65192008-07-18 09:01:10 +00003046- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003047 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003048
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003049- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3050 handling is now the same as that of other special attributes like __name__).
3051
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003052- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00003504- Issue #1631171: Re-implement the 'warnings' module in C (the
3505 original Python code has been kept as backup). This will allow for
3506 using the 'warning's machinery in such places as the parser where
3507 use of pure Python code is not possible. Both the ``showarning()``
3508 and ``formatwarning()`` gain an optional 'line' argument which is
3509 not called by default for backwards-compatibility reasons. Setting
3510 ``warnings.showwarning()`` to an implementation that lacks support
3511 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003574- Issue #2550: The approach used by client/server code for obtaining
3575 ports to listen on in network-oriented tests has been refined in an
3576 effort to facilitate running multiple instances of the entire
3577 regression test suite in parallel without issue.
3578 test_support.bind_port() has been fixed such that it will always
3579 return a unique port -- which wasn't always the case with the
3580 previous implementation, especially if socket options had been set
3581 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3582 new implementation of bind_port() will actually raise an exception
3583 if it is passed an AF_INET/SOCK_STREAM socket with either the
3584 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3585 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3586 the socket it's been passed. This currently only applies to
3587 Windows. This option prevents any other sockets from binding to the
3588 host/port we've bound to, thus removing the possibility of the
3589 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3590 when a second SOCK_STREAM socket binds and accepts to a host/port
3591 that's already been bound by another socket. The optional preferred
3592 port parameter to bind_port() has been removed. Under no
3593 circumstances should tests be hard coding ports!
3594
3595 test_support.find_unused_port() has also been introduced, which will
3596 pass a temporary socket object to bind_port() in order to obtain an
3597 unused port. The temporary socket object is then closed and
3598 deleted, and the port is returned. This method should only be used
3599 for obtaining an unused port in order to pass to an external program
3600 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3601 a parameter to a server-oriented class that doesn't give you direct
3602 access to the underlying socket used.
3603
3604 Finally, test_support.HOST has been introduced, which should be used
3605 for the host argument of any relevant socket calls (i.e. bind and
3606 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003607
3608 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003609 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003610 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3611 test_asynchat and test_socket_ssl.
3612
Georg Brandl3ee81df2008-05-17 18:14:43 +00003613 It is now possible for multiple instances of the regression test
3614 suite to run in parallel without issue.

3770 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00003771 platform.machine() and platform.processor() will report this
3772 information as well.

3881-----------------
3882
Fred Drakea8ee94b2008-03-01 02:45:07 +00003883- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003884 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003886- Issue #2067: file.__exit__() now calls subclasses' close() method.
3887
3888- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003889
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003890- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003891 issue 215555 for a discussion.
3892
Eric Smitha73fbe72008-02-23 03:09:44 +00003893- Added the future_builtins module, which contains hex() and oct().
3894 These are the PEP 3127 version of these functions, designed to be
3895 compatible with the hex() and oct() builtins from Python 3.0. They
3896 differ slightly in their output formats from the existing, unchanged
3897 Python 2.6 builtins. The expected usage of the future_builtins
3898 module is:
3899 from future_builtins import hex, oct
3900
Eric Smith7ef40bf2008-02-20 23:34:22 +00003901- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3902 exponents for exponents with absolute value < 100. Follows C99
3903 standard. This is a change on Windows, which would use 3 digits.
3904 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3905 so that any alterations it does to the resulting string will be
3906 available in stringlib/formatter.h (for float.__format__).
3907
Eric Smith5a3c1352008-02-19 13:21:56 +00003908- Implemented PEP 3101, Advanced String Formatting. This adds a new
3909 builtin format(); a format() method for str and unicode; a
3910 __format__() method to object, str, unicode, int, long, float, and
3911 datetime; the class string.Formatter; and the C API
3912 PyObject_Format().
3913
Georg Brandl3ee81df2008-05-17 18:14:43 +00003914- Fixed several potential crashes, all caused by specially crafted
3915 __del__ methods exploiting objects in temporarily inconsistent
3916 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003917
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003918- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003919 prevent a possible crash: an Abstract Base Class would try to access
3920 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003921

Georg Brandl3ee81df2008-05-17 18:14:43 +00003925- Clear all free lists during a gc.collect() of the highest generation
3926 in order to allow pymalloc to free more arenas. Python may give back
3927 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003928
Georg Brandl3ee81df2008-05-17 18:14:43 +00003929- Issue #2045: Fix an infinite recursion triggered when printing a
3930 subclass of collections.defaultdict, if its default_factory is set
3931 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003932
Christian Heimesf75dbef2008-02-08 00:11:31 +00003933- Fixed a minor memory leak in dictobject.c. The content of the free
3934 list was not freed on interpreter shutdown.
3935
Georg Brandl21e99f42010-03-07 15:23:59 +00003936- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003937 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003938
Georg Brandl3ee81df2008-05-17 18:14:43 +00003939- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3940 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003941 to compact the internal free lists of pre-allocted ints and floats.
3942
Georg Brandl3ee81df2008-05-17 18:14:43 +00003943- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3944 calls. Python expected the return type int but the fork familie
3945 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003946
Georg Brandl3ee81df2008-05-17 18:14:43 +00003947- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3957 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003958
Georg Brandl3ee81df2008-05-17 18:14:43 +00003959- Patch #1473257: generator objects gain a gi_code attribute. This is
3960 the same object as the func_code attribute of the function that
3961 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003962
Georg Brandl3ee81df2008-05-17 18:14:43 +00003963- Issue #1920: "while 0" statements were completely removed by the
3964 compiler, even in the presence of an "else" clause, which is
3965 supposed to be run when the condition is false. Now the compiler
3966 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003967
Guido van Rossumeead05f2008-01-24 18:21:02 +00003968- A few crashers fixed: weakref_in_del.py (issue #1377858);
3969 loosing_dict_ref.py (issue #1303614, test67.py);
3970 borrowed_ref_[34].py (not in tracker).
3971
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003972- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003973 suppressed while an extension is loaded by calling SetErrorMode in
3974 dynload_win.c. The error is still reported properly.
3975
Georg Brandl3ee81df2008-05-17 18:14:43 +00003976- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003977 several extension methods and modules do not work without unicode
3978 support.
3979
Georg Brandl26543b12008-01-21 18:36:51 +00003980- Issue #1882: when compiling code from a string, encoding cookies in the
3981 second line of code were not always recognized correctly.
3982
Georg Brandl14404b62008-01-19 19:27:05 +00003983- Issue #1679: "0x" was taken as a valid integer literal.
3984
Georg Brandl6caad7d2008-01-26 14:19:22 +00003985- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003986 added.
3987
Christian Heimesc94e2b52008-01-14 04:13:37 +00003988- sys.float_info / PyFloat_GetInfo: The floating point information
3989 object was converted from a dict to a specialized structseq object.
3990
Georg Brandl3ee81df2008-05-17 18:14:43 +00003991- Patch #1816: Added sys.flags structseq. It exposes the status of
3992 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003993
Georg Brandl3ee81df2008-05-17 18:14:43 +00003994- Objects/structseq.c: Implemented new structseq representation. The
3995 patch makes structseqs (e.g. the return value of os.stat) more
3996 readable.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004006- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4007 envvar and sys.dont_write_bytecode attribute. All these can be set
4008 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004009
Georg Brandl3ee81df2008-05-17 18:14:43 +00004010- Improve some exception messages when Windows fails to load an
4011 extension module. Now we get for example '%1 is not a valid Win32
4012 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004019- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004020 and INF. float("nan"), float("inf") and float("-inf") now work on
4021 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004023- Compiler now generates simpler and faster code for dictionary
4024 literals. The oparg for BUILD_MAP now indicates an estimated
4025 dictionary size. There is a new opcode, STORE_MAP, for adding
4026 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004055- Patch #1739468: Directories and zipfiles containing a __main__.py
4056 file can now be directly executed by passing their name to the
4057 interpreter. The directory/zipfile is automatically inserted as the
4058 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004060- Issue #1265: Fix a problem with sys.settrace, if the tracing
4061 function uses a generator expression when at the same time the
4062 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004063
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004064- sets and frozensets now have an isdisjoint() method.

4069
Georg Brandl21e99f42010-03-07 15:23:59 +00004070- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004071 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4072 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004073
Georg Brandl3ee81df2008-05-17 18:14:43 +00004074- Issue #1686386: Tuple's tp_repr did not take into account the
4075 possibility of having a self-referential tuple, which is possible
4076 from C code. Nor did object's tp_str consider that a type's tp_str
4077 could do something that could lead to an inifinite recursion.
4078 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4079 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004080
Georg Brandl3ee81df2008-05-17 18:14:43 +00004081- Issue #1164: It was possible to trigger deadlock when using the
4082 'print' statement to write to a file since the GIL was not released
4083 as needed. Now PyObject_Print() does the right thing along with
4084 various tp_print implementations of the built-in types and those in
4085 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004086
Georg Brandl3ee81df2008-05-17 18:14:43 +00004087- Issue #1147: Exceptions were directly allowing string exceptions in
4088 their throw() method even though string exceptions no longer
4089 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004091- Issue #1096: Prevent a segfault from getting the repr of a very
4092 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004093
Brett Cannon1e534b52007-09-07 04:18:30 +00004094- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004095 PyObject_Call() never calling back out to Python code to trigger
4096 recursion depth updates/checks. Required the creation of a static
4097 RuntimeError instance in case normalizing an exception put the
4098 recursion check value past its limit. Fixes crashers
4099 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004100

Neal Norwitz0ac60192007-05-27 04:08:54 +00004114- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004115 __*__ attributes. (Some already existed, e.g., __doc__ and
4116 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004117
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004118- Add -3 option to the interpreter to warn about features that are
4119 deprecated and will be changed/removed in Python 3.0.
4120
Georg Brandl2134e752007-05-21 20:34:16 +00004121- Patch #1686487: you can now pass any mapping after '**' in function
4122 calls.
4123
Collin Winter62903052007-05-18 23:11:24 +00004124- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125 "except E as target:". This is to provide forwards compatibility
4126 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004127
Brett Cannon229cee22007-05-05 01:34:02 +00004128- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004133- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004134 setting a plain string, ie don't expand to single letter identifiers.
4135
Raymond Hettinger13936692007-04-11 18:40:58 +00004136- Request #1191699: Slices can now be pickled.
4137
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004138- Request #1193128: str.translate() now allows a None argument for
4139 translations that only remove characters without re-mapping the
4140 remaining characters.
4141
Georg Brandl5cb76c12007-03-21 09:00:39 +00004142- Patch #1682205: a TypeError while unpacking an iterable is no longer

4146
Guido van Rossum143b5642007-03-23 04:58:42 +00004147- Bug #1683368: The object.__init__() and object.__new__() methods are
4148 now stricter in rejecting excess arguments. The only time when
4149 either allows excess arguments is when it is not overridden and the
4150 other one is. For backwards compatibility, when both are
4151 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004152 warning later). Also, type.__init__() insists on the same signature
4153 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004154
Georg Brandl3ee81df2008-05-17 18:14:43 +00004155- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4156 object to complex using its __complex__() method before falling back
4157 to the __float__() method. Therefore, the functions in the cmath
4158 module now can operate on objects that define a __complex__()
4159 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004160
Georg Brandl3ee81df2008-05-17 18:14:43 +00004161- Patch #1623563: allow __class__ assignment for classes with
4162 __slots__. The old and the new class are still required to have the
4163 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004164

4169 ``object.__reduce_ex__()`` is called with an object that is faking
4170 its type.

4176
Georg Brandl7b9c5552007-03-12 14:30:05 +00004177- Bug #1678647: write a newline after printing an exception in any
4178 case, even when converting the value to a string failed.
4179
Georg Brandl871f1bc2007-03-12 13:17:36 +00004180- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004181 its argument, if it exists. If not, it will work like before. This
4182 allows customizing the output of dir() in the presence of a
4183 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004185- Patch #922167: Python no longer segfaults when faced with infinitely
4186 self-recursive reload() calls (as reported by bug #742342).
4187
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188- Patch #1675981: remove unreachable code from ``type.__new__()``

4192 parthensized forms. This means complex(repr(x)) now works instead of
4193 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004194
Georg Brandlaa2321b2007-03-07 00:40:28 +00004195- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196 makes the filenames the warning module prints much more sensible
4197 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004198

Georg Brandl0fca97a2007-03-05 22:28:08 +00004210- Patch #1674228: when assigning a slice (old-style), check for the
4211 sq_ass_slice instead of the sq_slice slot.
4212
Georg Brandl3ee81df2008-05-17 18:14:43 +00004213- When printing an unraisable error, don't print exceptions. before
4214 the name. This duplicates the behavior whening normally printing
4215 exceptions.

Guido van Rossum8bc09652008-02-21 18:18:37 +00004357- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00004748 AttributeError instead of an IOError when the server's response
4749 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004750

4781
Georg Brandl92a6bae2007-03-13 17:43:32 +00004782- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004783 are set for invalid interpolation sequences that would lead to
4784 errors on reading back those values.

4840 TestCase and TestSuite subclasses (not instances) are no longer
4841 accepted in TestSuite.addTest(). This should cause no
4842 incompatibility since it never made sense with ordinary subclasses
4843 -- the failure just occurred later, with a more cumbersome
4844 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005233 time so that opening a database previously created with the DB_DUP
5234 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5235 opens. Specifically: dictionary assignment to a DB object will
5236 replace all values for a given key when the database allows
5237 duplicate values. DB users should use DB.put(k, v) when they want
5238 to store duplicates; not DB[k] = v.

5245 characters with ASCII value less than 32. Also, it correctly quotes
5246 dots only if they occur on a single line, as opposed to the previous
5247 behavior of quoting dots if they are the second character of any
5248 line.

5594 of w# format code incorrectly truncated the length to an int, even
5595 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5596 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005626- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5627 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
