Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00007What's New in Python 2.7 beta 1?
8================================
9
10*Release date: XXXX-XX-XX*
11
12Core and Builtins
13-----------------
14
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000015- Ensure that tokenization of identifiers is not affected by locale.
16
Tarek Ziadé00002952010-04-03 08:37:59 +000017- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
18
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000019- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
20
Eric Smithd44b2fc2010-04-02 12:30:56 +000021- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
22 is called with a non-empty format string. This is an effort to
23 future-proof user code. If a derived class does not currently
24 implement __format__ but later adds its own __format__, it would
25 most likely break user code that had supplied a format string. This
26 will be changed to a DeprecationWaring in Python 3.3 and it will be
27 an error in Python 3.4.
28
Antoine Pitroua57df2c2010-03-31 21:32:15 +000029- Issue #8268: Old-style classes (not just instances) now support weak
30 references.
31
Victor Stinner6cbf90f2010-03-25 00:21:53 +000032- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
33 optimizations are disabled when --with-pydebug is used.
34
Victor Stinnerc7790ed2010-03-22 12:36:28 +000035- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000036
Benjamin Peterson96545892010-03-21 20:21:00 +000037- Issue #6474: Make error message from passing an inadequate number of keyword
38 arguments to a function correct.
39
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000040- Issue #8164: Don't allow lambda functions to have a docstring.
41
Victor Stinner66644262010-03-10 22:30:19 +000042- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000043 (SIGINT). If an error occurs while importing the site module, the error is
44 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000045 module.
46
Collin Winter001a3952010-03-18 21:54:01 +000047- Code objects now support weak references.
48
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +000049Library
50-------
51
Mark Dickinson8a950712010-04-03 15:47:46 +000052- Issue #8257: The Decimal construct now accepts a float instance
53 directly, converting that float to a Decimal of equal value:
54
55 >>> Decimal(1.1)
56 Decimal('1.100000000000000088817841970012523233890533447265625')
57
Raymond Hettinger34c35b22010-04-03 10:22:00 +000058- collections.Counter() now supports a subtract() method.
59
Raymond Hettingera551f312010-04-04 18:34:45 +000060- the functools module now has a total_ordering() class decorator
61 to simplify the specifying rich comparisons.
62
63- The functools module also adds CmpToKey() as a tool to transition
64 old-style comparison functions to new-style key-functions.
65
Mark Dickinson7c63eee2010-04-02 22:27:36 +000066- Issue #8294: The Fraction constructor now accepts Decimal and float
67 instances directly.
68
Mark Dickinsone096e822010-04-02 10:17:07 +000069- Issue #7279: Comparisons involving a Decimal signaling NaN now
70 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000071 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
72 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000073
Mark Dickinson99d80962010-04-02 08:53:22 +000074- Issue #2531: Comparison operations between floats and Decimal
75 instances now return a result based on the numeric values of the
76 operands; previously they returned an arbitrary result based on
77 the relative ordering of id(float) and id(Decimal).
78
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000079- Issue #8233: When run as a script, py_compile.py optionally takes a single
80 argument `-` which tells it to read files to compile from stdin. Each line
81 is read on demand and the named file is compiled immediately. (Original
82 patch by Piotr Ożarowski).
83
84- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
85 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000086
Florent Xicluna58b65662010-03-30 16:29:03 +000087- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
88 form feed (0x0C) are now considered linebreaks, as specified in Unicode
89 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +000090 http://www.unicode.org/reports/tr14/
91
Mark Dickinson9588d992010-03-27 11:14:37 +000092- Comparisons using one of <, <=, >, >= between a complex instance and
93 a Fractions instance now raise TypeError instead of returning
94 True/False. This makes Fraction <=> complex comparisons consistent with
95 int <=> complex, float <=> complex, and complex <=> complex comparisons.
96
Michael Foorde6410c52010-03-29 20:04:23 +000097- Addition of ``WeakSet`` to the ``weakref`` module.
98
Vinay Sajipb0623d62010-03-24 14:31:21 +000099- logging: Added LOG_FTP to SysLogHandler and updated documentation.
100
Florent Xicluna176cda12010-03-22 22:52:11 +0000101- Issue #8205: Remove the "Modules" directory from sys.path when Python is
102 running from the build directory (POSIX only).
103
Florent Xiclunae1f4c922010-03-22 22:45:50 +0000104- Issue #7667: Fix doctest failures with non-ASCII paths.
105
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000106- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
107 didn't support chflags() (for example ZFS under FreeBSD). The error is
108 now silenced.
109
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000110- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
111 deprecated.
112
R. David Murrayc9d1a782010-03-22 15:55:09 +0000113- Issue #7860: platform.uname now reports the correct 'machine' type
114 when Python is running in WOW64 mode on 64 bit Windows.
115
Vinay Sajip804899b2010-03-22 15:29:01 +0000116- logging: Added getChild utility method to Logger and added isEnabledFor
117 method to LoggerAdapter.
118
Vinay Sajip31e928e2010-03-22 13:02:28 +0000119- Issue #8201: logging: Handle situation of non-ASCII and Unicode
120 logger names existing at the same time, causing a Unicode error
121 when configuration code attempted to sort the existing loggers.
122
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000123- Issue #8200: logging: Handle errors when multiprocessing is not
124 fully loaded when logging occurs.
125
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000126- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
127 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
128 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000129
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000130- Issue #8179: Fix macpath.realpath() on a non-existing path.
131
Florent Xicluna2e0a53f2010-03-18 21:50:06 +0000132- Issue #8024: Update the Unicode database to 5.2.
133
Antoine Pitroud7b731d2010-03-17 22:45:39 +0000134- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support
135 writing into objects supporting the new buffer API, for example bytearrays
136 or memoryviews.
137
Matthias Klose8b411682010-03-16 10:48:52 +0000138- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
139 with Tcl/Tk-8.5.
140

142
Matthias Klose358e7ff2010-03-15 13:42:23 +0000143- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
144 the locale.
145
Georg Brandlba83f822010-03-14 09:50:54 +0000146- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000147 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000148 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000149
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000150- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000151 for ``TimedRotatingFileHandler`` by using the modification time of an
152 existing log file to compute the next rollover time. If the log file does
153 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000154
Georg Brandlba83f822010-03-14 09:50:54 +0000155- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

159
Georg Brandlba83f822010-03-14 09:50:54 +0000160- Issue #7624: Fix ``isinstance(foo(), collections.Callable)`` for old-style
Florent Xicluna47627d52010-03-08 15:20:28 +0000161 classes.
162
Georg Brandlba83f822010-03-14 09:50:54 +0000163- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
164 a base64 transfer-encoded payload *after* decoding it; it no longer does.
165 This is a behavior change, so email's minor version number is now bumped, to
166 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000167
Larry Hastings3b958e32010-04-02 11:18:17 +0000168- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is

180-----------------
181
Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000182- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
183
Jesus Cea6557aac2010-03-22 14:22:26 +0000184- Issue #8156: bsddb module updated to version 4.8.4.
185 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
186 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000187
Matthias Klose817acef2010-03-15 00:02:36 +0000188- Issue #8142: Update libffi to the 3.0.9 release.
189
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000190- Issue #8300: When passing a non-integer argument to struct.pack with any
191 integer format code, struct.pack first attempts to convert the non-integer
192 using its __index__ method. If that method is non-existent or raises
193 TypeError it goes on to try the __int__ method, as described below.
194
Georg Brandlba83f822010-03-14 09:50:54 +0000195- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
196 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
197 argument's __int__ method to convert to an integer before packing. It also
198 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
199 was inconsistent: __int__ was used for some integer codes but not for others,
200 and the set of integer codes for which it was used differed between native
201 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000202
Brian Curtin19479fa2010-04-02 21:51:37 +0000203- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a
204 bug in the return value of QueryReflectionKey.

208
Georg Brandlba83f822010-03-14 09:50:54 +0000209- Issue #7993: Add a test of IO packet processing bandwidth to ccbench. It
210 measures the number of UDP packets processed per second depending on the
211 number of background CPU-bound Python threads.
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000212
Collin Wintera70f3492010-03-19 00:08:44 +0000213- python-config now supports multiple options on the same command line.

Martin v. Löwisbf0dfb32010-04-01 07:40:51 +0000218- Issue #8032: For gdb7, a python-gdb.py file is added to the build,
219 allowing to use advanced gdb features when debugging Python.
220
Antoine Pitrouf83b3082010-03-21 19:19:41 +0000221- Issue #1628484: The Makefile doesn't ignore the CFLAGS environment
222 variable anymore. It also forwards the LDFLAGS settings to the linker
223 when building a shared library.
224
Martin v. Löwis24e4e162010-03-15 13:00:17 +0000225- Issue #6716: Quote -x arguments of compileall in MSI installer.

Antoine Pitrou76c86492010-04-01 16:42:11 +0000232- Issue #8276: PyEval_CallObject() is now only available in macro form. The
233 function declaration, which was kept for backwards compatibility reasons,
234 is now removed (the macro was introduced in 1997!).
235
Larry Hastings402b73f2010-03-25 00:54:54 +0000236- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000237 from Python 3.1. All existing Python CObjects in the main distribution
238 have been converted to capsules. To address backwards-compatibility
239 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

Georg Brandlba83f822010-03-14 09:50:54 +0000485 file position when calling `truncate()`. It would previously change the file

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

583Core and Builtins
584-----------------
585
Georg Brandlba83f822010-03-14 09:50:54 +0000586- The ``__complex__()`` method is now looked up on the class of instances to
587 make it consistent with other special methods.

591
Mark Dickinson1b34d252010-01-01 17:27:30 +0000592- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000593 DeprecationWarning when passed a float argument where an integer was expected.
594 These functions and methods now raise TypeError instead. The majority of the
595 effects of this change are in the extension modules, but some core functions
596 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
597 and many unicode/str methods.

611 of integers: the result of a/b is now correctly rounded for ints a and b (at
612 least on IEEE 754 platforms), and in particular does not depend on the
613 internal representation of a long.

621
Georg Brandlba83f822010-03-14 09:50:54 +0000622 These executables now work properly with the arch(1) command: ``arch -ppc
623 python`` will start a universal binary version of python in PPC mode (unlike
624 previous releases).

771 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +0000780- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
781 decimal string that's guaranteed to round back to x under correct rounding
782 (with round-half-to-even rounding mode). Previously it gave a string based on
783 rounding x to 17 decimal digits. repr(x) for a complex number behaves
784 similarly. On platforms where the correctly-rounded strtod and dtoa code is
785 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +0000787- Issue #7117: On almost all platforms: float-to-string and string-to-float
788 conversions within Python are now correctly rounded. Places these conversions
789 occur include: str for floats and complex numbers; the float and complex
790 constructors; old-style and new-style numeric formatting; serialization and
791 deserialization of floats and complex numbers using marshal, pickle and json;
792 parsing of float and imaginary literals in Python code; Decimal-to-float
793 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000794
Georg Brandlba83f822010-03-14 09:50:54 +0000795 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
796 providing correctly-rounded strtod and dtoa C functions. This code is
797 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
798 the C compiler. There may be a small number of platforms on which correct
799 operation of this code cannot be guaranteed, so the code is not used: notably,
800 this applies to platforms where the C double format is not IEEE 754 binary64,
801 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
802 and Python's configure script is unable to determine how to change the FPU
803 precision. On these platforms conversions use the platform strtod and dtoa,
804 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000806- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
807 uses the correctly-rounded string <-> float conversions described above (when
808 available), and so produces correctly rounded results that will display nicely
809 under the float repr. There are two related small changes: (1) round now
810 accepts any class with an ``__index__()`` method for its second argument (but
811 no longer accepts floats for the second argument), and (2) an excessively
812 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
813 raises an exception.

2396 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2397 neither __int__ nor __long__, TypeError used to be raised (with a

2595
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002596- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2597 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2598 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2599 ``printf`` function, whereas PyString_FromFormat has an independent
2600 implementation and uses "%zd" on all platforms for size_t values.
2601 This makes a difference on win64, where ``printf`` needs "%Id" to display
2602 64bit values.

2608 object; previously an int would be returned for small values. the __long__
2609 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00002621- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002622 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2623 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2624 when given a tuple of classes as second argument, were looking up
2625 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2626 type object.

2697 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2698 for catch_warnings() also led to an improvement in the raising of a
2699 DeprecationWarning related to warnings.warn_explicit().
2700

2723
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002724- Issue #2975: When compiling several extension modules with Visual Studio 2008

2726 without limit.
2727
Benjamin Peterson37346b22008-08-23 20:27:43 +00002728- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2729 exploitation of poor argument checking.
2730
Gerhard Häringef2276b2008-09-12 13:54:06 +00002731- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002765What's New in Python 2.6 beta 3?
2766================================
2767
Barry Warsaw07a4a382008-08-21 01:15:08 +00002768*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002769
2770Core and Builtins
2771-----------------
2772
Guido van Rossumf8402962008-08-20 15:01:50 +00002773- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2774 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2775 extensions do not automatically benefit from the class attribute
2776 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2777 to their tp_flags field if they care. This is a backwards
2778 compatibility feature; in 3.0, all types will use the cache by
2779 default.
2780
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002781- Keyword arguments can now follow starred arguments. (``f(a, *args,
2782 keyword=23)`` is now valid syntax.)
2783
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002784- ctypes function pointers that are COM methods have a boolean True
2785 value again.
2786
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002787- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2788 by denying s# to parse objects that have a releasebuffer procedure,
2789 and introducing s*.
2790
Georg Brandl1e13ea92008-08-11 09:07:59 +00002791- Issue #3537: Fix an assertion failure when an empty but presized dict
2792 object was stored in the freelist.
2793
Mark Dickinsonb6467572008-08-04 21:30:09 +00002794- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2795 ValueError consistently across platforms.
2796
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002797- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2798 (64bit Unix, for example), unichr() would truncate its argument and return
2799 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2800
Neal Norwitze7d8be82008-07-31 17:17:14 +00002801- Apply security patches from Apple.
2802
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002803- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2804 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2805
Antoine Pitrou92f82162008-07-25 22:22:08 +00002806- Issue #1819: function calls with several named parameters are now on
2807 average 35% faster (as measured by pybench).
2808
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002809- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2810 the python debugger steps into a class statement: the free variables (local
2811 variables defined in an outer scope) would be deleted from the outer scope.
2812
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002813- Issue #2620: Overflow checking when allocating or reallocating memory
2814 was not always being done properly in some python types and extension
2815 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2816 all been updated to perform better checks and places in the code that
2817 would previously leak memory on the error path when such an allocation
2818 failed have been fixed.

2822
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002823- Issue #3612: Added some missing basic types in ctypes.wintypes.
2824
Benjamin Petersone977ad42008-08-20 01:42:01 +00002825- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2826 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2827
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002828- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2829 version reported by these tools does not necessarily follow the python
2830 version numbering scheme, so the module is less strict when parsing it.
2831
Nick Coghlanf70385a2008-08-18 12:42:46 +00002832- Issue #2235: Added Py3k warnings for types which will become unhashable
2833 under the stricter __hash__ inheritance rules in 3.0. Several types
2834 which did not meet the rules for hash invariants and were already
2835 unhashable in 3.0 have now been explicitly flagged as unhashable in
2836 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2837 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2838
Brett Cannon88f801d2008-08-18 00:46:22 +00002839- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2840 imported into the module but exposed as part of the module's API.
2841
Brett Cannon7b96f072008-08-18 00:41:11 +00002842- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2843
Brett Cannon46225e72008-08-18 00:36:52 +00002844- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002846- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2847
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002848- Issue #3575: Incremental decoder's decode function now takes bytearray
2849 by using 's*' instead of 't#'.
2850
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002851- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002852 fails unicode conversion on 2nd parameter. (windows only)
2853
Facundo Batista94f243a2008-08-17 03:38:39 +00002854- Issue 2464. urllib2 now supports a malformation in the URL received
2855 in a redirect.
2856
Brett Cannonabe423e2008-08-16 21:47:07 +00002857- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002858 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002859
Facundo Batistaeb90b782008-08-16 14:44:07 +00002860- Issue #2776: fixed small issue when handling an URL with double slash
2861 after a 302 response in the case of not going through a proxy.
2862
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002863- Issue #2676: in the email package, content-type parsing was hanging on
2864 pathological input because of quadratic or exponential behaviour of a
2865 regular expression.
2866
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002867- Issue #3476: binary buffered reading through the new "io" library is now
2868 thread-safe.
2869
Brett Cannonbf3157b2008-08-14 05:00:03 +00002870- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2871 since mimetools itself is deprecated. Because modules are cached, all
2872 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2873
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002874- Issue #3134: shutil referenced undefined WindowsError symbol.
2875
Robert Schuppenies14646332008-08-10 11:01:53 +00002876- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2877 menu entries were not deleted.
2878
Brett Cannon83e81842008-08-09 23:30:55 +00002879- Copied the implementation of reduce() to _functools.reduce() to have a
2880 version that did not raise a DeprecationWarning under -3.
2881
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002882- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2883 a MemoryError rather than silently stop the iteration.
2884
Guido van Rossum59ce9012008-08-09 14:55:34 +00002885- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2886 to _sre.compile() will now be rejected. This should not affect anybody
2887 since the re.compile() function never generates invalid re-bytecode.
2888
Skip Montanaroa032bf42008-08-08 22:52:51 +00002889- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2890 upon first access it can be automatically initialized from the csv file if
2891 it wasn't initialized during instantiation.
2892
Brett Cannon3aa2a492008-08-06 22:28:09 +00002893- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2894 the reload() built-in has been removed.
2895
Brett Cannon7e30b672008-08-04 21:52:25 +00002896- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002897 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002908 asking for a specific length. This problem only affected files opened
2909 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002910

2960================================
2961
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002962*Release date: 17-Jul-2008*

2965-----------------
2966
Georg Brandl3e483f62008-07-16 22:57:41 +00002967- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2968 its methods now allow for items objects that can be converted to
2969 an integer using operator.index().
2970
Mark Dickinson64b7e502008-07-16 09:40:03 +00002971- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2972 produced a ValueError instead of giving the correct float.
2973
Eric Smitha5fa5a22008-07-16 00:11:49 +00002974- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2975 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2976
Mark Dickinson7103aa42008-07-15 19:08:33 +00002977- Issue #3008: the float type has a new instance method 'float.hex'
2978 and a new class method 'float.fromhex' to convert floating-point
2979 numbers to and from hexadecimal strings, respectively.
2980
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002981- Issue #2235: __hash__ is once again inherited by default. To allow
2982 collections.Hashable to remain meaningful in the presence of the
2983 default hash implementation (object.__hash__), it is now possible
2984 to explicit block inheritance of hash by setting __hash__=None at
2985 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2986 level.
2987
Nick Coghlanb028f502008-07-13 14:52:36 +00002988- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2989 the parent module cannot be found while performing an absolute import.
2990 This means that an incorrectly defined __package__ attribute will
2991 now only prevent relative imports in that module rather than causing
2992 all imports from that module to fail.
2993
Nick Coghlan14ff9942008-07-08 14:21:42 +00002994- Issue #2517: Allow unicode messages in Exceptions again by correctly

2999 set to a custom object whose write() method happens to install
3000 another file in sys.stdout.

3003 threading.local: the first member set by a thread could be saved in
3004 another thread's dictionary.
3005
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003006- Issue #3004: Minor change to slice.indices(): the start and stop
3007 arguments are now treated identically, making the behaviour easier
3008 to describe and understand. For example, slice(None, -10,
3009 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3010 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3011 10, -1).
3012
Georg Brandl278fc502008-07-19 12:46:12 +00003013- Issue #3219: Calling a function with repeated keyword arguments,
3014 f(a=2, a=23), would not cause a syntax error. This was a regression
3015 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003016
Georg Brandl278fc502008-07-19 12:46:12 +00003017- Issue #2862: Make int and float freelist management consistent with
3018 other freelists. Changes their CompactFreeList apis into
3019 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003024- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3025 api functions without holding the GIL, which could lead to a fatal
3026 error when they failed.
3027
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003028- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003052
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003053- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3054 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003055 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003056 content-length. The problem had been corrected in the 2.4 branch, but never
3057 merged into trunk.
3058

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003072- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3073 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003527- Issue #1631171: Re-implement the 'warnings' module in C (the
3528 original Python code has been kept as backup). This will allow for
3529 using the 'warning's machinery in such places as the parser where
3530 use of pure Python code is not possible. Both the ``showarning()``
3531 and ``formatwarning()`` gain an optional 'line' argument which is
3532 not called by default for backwards-compatibility reasons. Setting
3533 ``warnings.showwarning()`` to an implementation that lacks support
3534 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003597- Issue #2550: The approach used by client/server code for obtaining
3598 ports to listen on in network-oriented tests has been refined in an
3599 effort to facilitate running multiple instances of the entire
3600 regression test suite in parallel without issue.
3601 test_support.bind_port() has been fixed such that it will always
3602 return a unique port -- which wasn't always the case with the
3603 previous implementation, especially if socket options had been set
3604 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3605 new implementation of bind_port() will actually raise an exception
3606 if it is passed an AF_INET/SOCK_STREAM socket with either the
3607 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3608 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3609 the socket it's been passed. This currently only applies to
3610 Windows. This option prevents any other sockets from binding to the
3611 host/port we've bound to, thus removing the possibility of the
3612 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3613 when a second SOCK_STREAM socket binds and accepts to a host/port
3614 that's already been bound by another socket. The optional preferred
3615 port parameter to bind_port() has been removed. Under no
3616 circumstances should tests be hard coding ports!
3617
3618 test_support.find_unused_port() has also been introduced, which will
3619 pass a temporary socket object to bind_port() in order to obtain an
3620 unused port. The temporary socket object is then closed and
3621 deleted, and the port is returned. This method should only be used
3622 for obtaining an unused port in order to pass to an external program
3623 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3624 a parameter to a server-oriented class that doesn't give you direct
3625 access to the underlying socket used.
3626
3627 Finally, test_support.HOST has been introduced, which should be used
3628 for the host argument of any relevant socket calls (i.e. bind and
3629 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003630
3631 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003632 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003633 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3634 test_asynchat and test_socket_ssl.
3635
Georg Brandl3ee81df2008-05-17 18:14:43 +00003636 It is now possible for multiple instances of the regression test
3637 suite to run in parallel without issue.

3904-----------------
3905
Fred Drakea8ee94b2008-03-01 02:45:07 +00003906- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003907 644. The mode is now inherited from the py file.

3910
3911- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003912
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003913- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003914 issue 215555 for a discussion.
3915
Eric Smitha73fbe72008-02-23 03:09:44 +00003916- Added the future_builtins module, which contains hex() and oct().
3917 These are the PEP 3127 version of these functions, designed to be
3918 compatible with the hex() and oct() builtins from Python 3.0. They
3919 differ slightly in their output formats from the existing, unchanged
3920 Python 2.6 builtins. The expected usage of the future_builtins
3921 module is:
3922 from future_builtins import hex, oct
3923
Eric Smith7ef40bf2008-02-20 23:34:22 +00003924- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3925 exponents for exponents with absolute value < 100. Follows C99
3926 standard. This is a change on Windows, which would use 3 digits.
3927 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3928 so that any alterations it does to the resulting string will be
3929 available in stringlib/formatter.h (for float.__format__).
3930
Eric Smith5a3c1352008-02-19 13:21:56 +00003931- Implemented PEP 3101, Advanced String Formatting. This adds a new
3932 builtin format(); a format() method for str and unicode; a
3933 __format__() method to object, str, unicode, int, long, float, and
3934 datetime; the class string.Formatter; and the C API
3935 PyObject_Format().
3936
Georg Brandl3ee81df2008-05-17 18:14:43 +00003937- Fixed several potential crashes, all caused by specially crafted
3938 __del__ methods exploiting objects in temporarily inconsistent
3939 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003940
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003941- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003942 prevent a possible crash: an Abstract Base Class would try to access
3943 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003948- Clear all free lists during a gc.collect() of the highest generation
3949 in order to allow pymalloc to free more arenas. Python may give back
3950 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003951
Georg Brandl3ee81df2008-05-17 18:14:43 +00003952- Issue #2045: Fix an infinite recursion triggered when printing a
3953 subclass of collections.defaultdict, if its default_factory is set
3954 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003955
Christian Heimesf75dbef2008-02-08 00:11:31 +00003956- Fixed a minor memory leak in dictobject.c. The content of the free
3957 list was not freed on interpreter shutdown.
3958
Georg Brandl21e99f42010-03-07 15:23:59 +00003959- Limit free list of method and built-in function objects to 256

3963 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003964 to compact the internal free lists of pre-allocted ints and floats.
3965
Georg Brandl3ee81df2008-05-17 18:14:43 +00003966- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3967 calls. Python expected the return type int but the fork familie
3968 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003982- Patch #1473257: generator objects gain a gi_code attribute. This is
3983 the same object as the func_code attribute of the function that
3984 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003985
Georg Brandl3ee81df2008-05-17 18:14:43 +00003986- Issue #1920: "while 0" statements were completely removed by the
3987 compiler, even in the presence of an "else" clause, which is
3988 supposed to be run when the condition is false. Now the compiler
3989 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003990

Georg Brandl6caad7d2008-01-26 14:19:22 +00004008- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004009 added.
4010
Christian Heimesc94e2b52008-01-14 04:13:37 +00004011- sys.float_info / PyFloat_GetInfo: The floating point information
4012 object was converted from a dict to a specialized structseq object.
4013
Georg Brandl3ee81df2008-05-17 18:14:43 +00004014- Patch #1816: Added sys.flags structseq. It exposes the status of
4015 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004016
Georg Brandl3ee81df2008-05-17 18:14:43 +00004017- Objects/structseq.c: Implemented new structseq representation. The
4018 patch makes structseqs (e.g. the return value of os.stat) more
4019 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004020
Georg Brandl3ee81df2008-05-17 18:14:43 +00004021- Patch #1700288: added a type attribute cache that caches method
4022 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004023
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004024- Bug #1776: __import__() no longer accepts filenames on any platform.
4025 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004026
Georg Brandlaed6c662008-01-07 17:25:53 +00004027- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4028
Georg Brandl3ee81df2008-05-17 18:14:43 +00004029- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4030 envvar and sys.dont_write_bytecode attribute. All these can be set
4031 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004032
Georg Brandl3ee81df2008-05-17 18:14:43 +00004033- Improve some exception messages when Windows fails to load an
4034 extension module. Now we get for example '%1 is not a valid Win32
4035 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004036
Georg Brandl3ee81df2008-05-17 18:14:43 +00004037- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004039- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4040 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004041
Christian Heimes0a8143f2007-12-18 23:22:54 +00004042- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004043 and INF. float("nan"), float("inf") and float("-inf") now work on
4044 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004045
Georg Brandl3ee81df2008-05-17 18:14:43 +00004046- Compiler now generates simpler and faster code for dictionary
4047 literals. The oparg for BUILD_MAP now indicates an estimated
4048 dictionary size. There is a new opcode, STORE_MAP, for adding
4049 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004059- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004060 SystemError.
4061
Nick Coghlanef01d822007-12-03 12:55:17 +00004062- PEP 366: Allow explicit relative imports when executing modules

4067 running, and if the deallocation of its frames somehow calls the
4068 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004069

Georg Brandl3ee81df2008-05-17 18:14:43 +00004078- Patch #1739468: Directories and zipfiles containing a __main__.py
4079 file can now be directly executed by passing their name to the
4080 interpreter. The directory/zipfile is automatically inserted as the
4081 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004082
Georg Brandl3ee81df2008-05-17 18:14:43 +00004083- Issue #1265: Fix a problem with sys.settrace, if the tracing
4084 function uses a generator expression when at the same time the
4085 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004086
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004087- sets and frozensets now have an isdisjoint() method.
4088
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004089- optimize the performance of builtin.sum().
4090
Neal Norwitz44f326e2007-10-05 05:29:17 +00004091- Fix warnings found by the new version of the Coverity checker.
4092
Georg Brandl21e99f42010-03-07 15:23:59 +00004093- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004094 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4095 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004096
Georg Brandl3ee81df2008-05-17 18:14:43 +00004097- Issue #1686386: Tuple's tp_repr did not take into account the
4098 possibility of having a self-referential tuple, which is possible
4099 from C code. Nor did object's tp_str consider that a type's tp_str
4100 could do something that could lead to an inifinite recursion.
4101 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4102 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004103
Georg Brandl3ee81df2008-05-17 18:14:43 +00004104- Issue #1164: It was possible to trigger deadlock when using the
4105 'print' statement to write to a file since the GIL was not released
4106 as needed. Now PyObject_Print() does the right thing along with
4107 various tp_print implementations of the built-in types and those in
4108 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004109
Georg Brandl3ee81df2008-05-17 18:14:43 +00004110- Issue #1147: Exceptions were directly allowing string exceptions in
4111 their throw() method even though string exceptions no longer
4112 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004113
Georg Brandl3ee81df2008-05-17 18:14:43 +00004114- Issue #1096: Prevent a segfault from getting the repr of a very
4115 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004116
Brett Cannon1e534b52007-09-07 04:18:30 +00004117- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118 PyObject_Call() never calling back out to Python code to trigger
4119 recursion depth updates/checks. Required the creation of a static
4120 RuntimeError instance in case normalizing an exception put the
4121 recursion check value past its limit. Fixes crashers
4122 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004123
Georg Brandl3ee81df2008-05-17 18:14:43 +00004124- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004137- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138 __*__ attributes. (Some already existed, e.g., __doc__ and
4139 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004140
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004141- Add -3 option to the interpreter to warn about features that are
4142 deprecated and will be changed/removed in Python 3.0.
4143
Georg Brandl2134e752007-05-21 20:34:16 +00004144- Patch #1686487: you can now pass any mapping after '**' in function
4145 calls.
4146
Collin Winter62903052007-05-18 23:11:24 +00004147- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004148 "except E as target:". This is to provide forwards compatibility
4149 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004150
Brett Cannon229cee22007-05-05 01:34:02 +00004151- Deprecate BaseException.message as per PEP 352.
4152
Georg Brandl3ee81df2008-05-17 18:14:43 +00004153- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004154 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004155
Vinay Sajip8549ce32007-05-06 17:53:37 +00004156- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004157 setting a plain string, ie don't expand to single letter identifiers.
4158
Raymond Hettinger13936692007-04-11 18:40:58 +00004159- Request #1191699: Slices can now be pickled.
4160
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004161- Request #1193128: str.translate() now allows a None argument for
4162 translations that only remove characters without re-mapping the
4163 remaining characters.
4164
Georg Brandl5cb76c12007-03-21 09:00:39 +00004165- Patch #1682205: a TypeError while unpacking an iterable is no longer
4166 masked by a generic one with the message "unpack non-sequence".
4167
Neal Norwitzaa754b72007-03-21 06:39:48 +00004168- Remove unused file Python/fmod.c.
4169
Guido van Rossum143b5642007-03-23 04:58:42 +00004170- Bug #1683368: The object.__init__() and object.__new__() methods are
4171 now stricter in rejecting excess arguments. The only time when
4172 either allows excess arguments is when it is not overridden and the
4173 other one is. For backwards compatibility, when both are
4174 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004175 warning later). Also, type.__init__() insists on the same signature
4176 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004177
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4179 object to complex using its __complex__() method before falling back
4180 to the __float__() method. Therefore, the functions in the cmath
4181 module now can operate on objects that define a __complex__()
4182 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004183
Georg Brandl3ee81df2008-05-17 18:14:43 +00004184- Patch #1623563: allow __class__ assignment for classes with
4185 __slots__. The old and the new class are still required to have the
4186 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004187

4192 ``object.__reduce_ex__()`` is called with an object that is faking
4193 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004194
Georg Brandl3ee81df2008-05-17 18:14:43 +00004195- Patch #1680015: Don't modify __slots__ tuple if it contains an

4199
Georg Brandl7b9c5552007-03-12 14:30:05 +00004200- Bug #1678647: write a newline after printing an exception in any
4201 case, even when converting the value to a string failed.
4202
Georg Brandl871f1bc2007-03-12 13:17:36 +00004203- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004204 its argument, if it exists. If not, it will work like before. This
4205 allows customizing the output of dir() in the presence of a
4206 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004207
Collin Winter276887b2007-03-12 16:11:39 +00004208- Patch #922167: Python no longer segfaults when faced with infinitely
4209 self-recursive reload() calls (as reported by bug #742342).
4210
Georg Brandl3ee81df2008-05-17 18:14:43 +00004211- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004214- Patch #1491866: change the complex() constructor to allow
4215 parthensized forms. This means complex(repr(x)) now works instead of
4216 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004217
Georg Brandlaa2321b2007-03-07 00:40:28 +00004218- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004219 makes the filenames the warning module prints much more sensible
4220 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004221
Georg Brandl49aafc92007-03-07 00:34:46 +00004222- Variant of patch #697613: don't exit the interpreter on a SystemExit
4223 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004224 variable is given, but break into the interactive interpreter just
4225 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004233- Patch #1674228: when assigning a slice (old-style), check for the
4234 sq_ass_slice instead of the sq_slice slot.
4235
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236- When printing an unraisable error, don't print exceptions. before
4237 the name. This duplicates the behavior whening normally printing
4238 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004239

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004740- Added a timeout parameter to the constructor of other protocols
4741 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4742 work started with create_connection() and timeout in httplib, and
4743 closes patch #723312.
4744
Vinay Sajip8549ce32007-05-06 17:53:37 +00004745- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00004771 AttributeError instead of an IOError when the server's response
4772 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004773

Georg Brandl3ee81df2008-05-17 18:14:43 +00004778- Patch #1429539: pdb now correctly initializes the __main__ module
4779 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004780 correctly now.
4781

Georg Brandl3ee81df2008-05-17 18:14:43 +00004789- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00004802- Patch #1581073: add a flag to textwrap that prevents the dropping of
4803 whitespace while wrapping.
4804
Georg Brandl92a6bae2007-03-13 17:43:32 +00004805- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004806 are set for invalid interpolation sequences that would lead to
4807 errors on reading back those values.

4850 returned string up to the first NUL character.

4861
Georg Brandl3ee81df2008-05-17 18:14:43 +00004862- unittest now verifies more of its assumptions. In particular,
4863 TestCase and TestSuite subclasses (not instances) are no longer
4864 accepted in TestSuite.addTest(). This should cause no
4865 incompatibility since it never made sense with ordinary subclasses
4866 -- the failure just occurred later, with a more cumbersome
4867 exception.

4877
Georg Brandl3ee81df2008-05-17 18:14:43 +00004878- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00005256 time so that opening a database previously created with the DB_DUP
5257 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5258 opens. Specifically: dictionary assignment to a DB object will
5259 replace all values for a given key when the database allows
5260 duplicate values. DB users should use DB.put(k, v) when they want
5261 to store duplicates; not DB[k] = v.

5268 characters with ASCII value less than 32. Also, it correctly quotes
5269 dots only if they occur on a single line, as opposed to the previous
5270 behavior of quoting dots if they are the second character of any
5271 line.
