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

11
12Core and Builtins
13-----------------
14
Tarek Ziadé00002952010-04-03 08:37:59 +000015- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
16
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000017- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
18
Eric Smithd44b2fc2010-04-02 12:30:56 +000019- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
20 is called with a non-empty format string. This is an effort to
21 future-proof user code. If a derived class does not currently
22 implement __format__ but later adds its own __format__, it would
23 most likely break user code that had supplied a format string. This
24 will be changed to a DeprecationWaring in Python 3.3 and it will be
25 an error in Python 3.4.
26
Antoine Pitroua57df2c2010-03-31 21:32:15 +000027- Issue #8268: Old-style classes (not just instances) now support weak
28 references.
29
Victor Stinner6cbf90f2010-03-25 00:21:53 +000030- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
31 optimizations are disabled when --with-pydebug is used.
32
Victor Stinnerc7790ed2010-03-22 12:36:28 +000033- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000034
Benjamin Peterson96545892010-03-21 20:21:00 +000035- Issue #6474: Make error message from passing an inadequate number of keyword
36 arguments to a function correct.
37
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000038- Issue #8164: Don't allow lambda functions to have a docstring.
39
Victor Stinner66644262010-03-10 22:30:19 +000040- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000041 (SIGINT). If an error occurs while importing the site module, the error is
42 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000043 module.
44
Collin Winter001a3952010-03-18 21:54:01 +000045- Code objects now support weak references.

48-------
49
Mark Dickinson8a950712010-04-03 15:47:46 +000050- Issue #8257: The Decimal construct now accepts a float instance
51 directly, converting that float to a Decimal of equal value:
52
53 >>> Decimal(1.1)
54 Decimal('1.100000000000000088817841970012523233890533447265625')
55
Raymond Hettinger34c35b22010-04-03 10:22:00 +000056- collections.Counter() now supports a subtract() method.
57
Mark Dickinson7c63eee2010-04-02 22:27:36 +000058- Issue #8294: The Fraction constructor now accepts Decimal and float
59 instances directly.
60
Mark Dickinsone096e822010-04-02 10:17:07 +000061- Issue #7279: Comparisons involving a Decimal signaling NaN now
62 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000063 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
64 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000065
Mark Dickinson99d80962010-04-02 08:53:22 +000066- Issue #2531: Comparison operations between floats and Decimal
67 instances now return a result based on the numeric values of the
68 operands; previously they returned an arbitrary result based on
69 the relative ordering of id(float) and id(Decimal).
70
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000071- Issue #8233: When run as a script, py_compile.py optionally takes a single
72 argument `-` which tells it to read files to compile from stdin. Each line
73 is read on demand and the named file is compiled immediately. (Original
74 patch by Piotr Ożarowski).
75
76- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
77 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000078
Florent Xicluna58b65662010-03-30 16:29:03 +000079- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
80 form feed (0x0C) are now considered linebreaks, as specified in Unicode
81 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +000082 http://www.unicode.org/reports/tr14/
83
Mark Dickinson9588d992010-03-27 11:14:37 +000084- Comparisons using one of <, <=, >, >= between a complex instance and
85 a Fractions instance now raise TypeError instead of returning
86 True/False. This makes Fraction <=> complex comparisons consistent with
87 int <=> complex, float <=> complex, and complex <=> complex comparisons.
88
Michael Foorde6410c52010-03-29 20:04:23 +000089- Addition of ``WeakSet`` to the ``weakref`` module.
90
Vinay Sajipb0623d62010-03-24 14:31:21 +000091- logging: Added LOG_FTP to SysLogHandler and updated documentation.
92
Florent Xicluna176cda12010-03-22 22:52:11 +000093- Issue #8205: Remove the "Modules" directory from sys.path when Python is
94 running from the build directory (POSIX only).
95
Florent Xiclunae1f4c922010-03-22 22:45:50 +000096- Issue #7667: Fix doctest failures with non-ASCII paths.
97
Antoine Pitrou513d9ae2010-03-22 19:59:46 +000098- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
99 didn't support chflags() (for example ZFS under FreeBSD). The error is
100 now silenced.
101
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000102- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
103 deprecated.
104
R. David Murrayc9d1a782010-03-22 15:55:09 +0000105- Issue #7860: platform.uname now reports the correct 'machine' type
106 when Python is running in WOW64 mode on 64 bit Windows.
107
Vinay Sajip804899b2010-03-22 15:29:01 +0000108- logging: Added getChild utility method to Logger and added isEnabledFor
109 method to LoggerAdapter.
110
Vinay Sajip31e928e2010-03-22 13:02:28 +0000111- Issue #8201: logging: Handle situation of non-ASCII and Unicode
112 logger names existing at the same time, causing a Unicode error
113 when configuration code attempted to sort the existing loggers.
114
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000115- Issue #8200: logging: Handle errors when multiprocessing is not
116 fully loaded when logging occurs.
117
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000118- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
119 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
120 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000121
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000122- Issue #8179: Fix macpath.realpath() on a non-existing path.
123
Florent Xicluna2e0a53f2010-03-18 21:50:06 +0000124- Issue #8024: Update the Unicode database to 5.2.
125
Antoine Pitroud7b731d2010-03-17 22:45:39 +0000126- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support
127 writing into objects supporting the new buffer API, for example bytearrays
128 or memoryviews.
129
Matthias Klose8b411682010-03-16 10:48:52 +0000130- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
131 with Tcl/Tk-8.5.
132
Matthias Kloseb13d04c2010-03-15 17:44:12 +0000133- Issue #8140: extend compileall to compile single files. Add -i option.
134
Matthias Klose358e7ff2010-03-15 13:42:23 +0000135- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
136 the locale.
137
Georg Brandlba83f822010-03-14 09:50:54 +0000138- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000139 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000140 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000141
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000142- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000143 for ``TimedRotatingFileHandler`` by using the modification time of an
144 existing log file to compute the next rollover time. If the log file does
145 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000146
Georg Brandlba83f822010-03-14 09:50:54 +0000147- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

151
Georg Brandlba83f822010-03-14 09:50:54 +0000152- Issue #7624: Fix ``isinstance(foo(), collections.Callable)`` for old-style
Florent Xicluna47627d52010-03-08 15:20:28 +0000153 classes.
154
Georg Brandlba83f822010-03-14 09:50:54 +0000155- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
156 a base64 transfer-encoded payload *after* decoding it; it no longer does.
157 This is a behavior change, so email's minor version number is now bumped, to
158 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000159
Larry Hastings3b958e32010-04-02 11:18:17 +0000160- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is

173
Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000174- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
175
Jesus Cea6557aac2010-03-22 14:22:26 +0000176- Issue #8156: bsddb module updated to version 4.8.4.
177 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
178 This update drops support for Berkeley DB 4.0, and adds support for 4.8.

Matthias Klose817acef2010-03-15 00:02:36 +0000180- Issue #8142: Update libffi to the 3.0.9 release.
181
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000182- Issue #8300: When passing a non-integer argument to struct.pack with any
183 integer format code, struct.pack first attempts to convert the non-integer
184 using its __index__ method. If that method is non-existent or raises
185 TypeError it goes on to try the __int__ method, as described below.
186
Georg Brandlba83f822010-03-14 09:50:54 +0000187- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
188 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
189 argument's __int__ method to convert to an integer before packing. It also
190 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
191 was inconsistent: __int__ was used for some integer codes but not for others,
192 and the set of integer codes for which it was used differed between native
193 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000194
Brian Curtin19479fa2010-04-02 21:51:37 +0000195- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a
196 bug in the return value of QueryReflectionKey.

Georg Brandlba83f822010-03-14 09:50:54 +0000201- Issue #7993: Add a test of IO packet processing bandwidth to ccbench. It
202 measures the number of UDP packets processed per second depending on the
203 number of background CPU-bound Python threads.
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000204
Collin Wintera70f3492010-03-19 00:08:44 +0000205- python-config now supports multiple options on the same command line.

Martin v. Löwisbf0dfb32010-04-01 07:40:51 +0000210- Issue #8032: For gdb7, a python-gdb.py file is added to the build,
211 allowing to use advanced gdb features when debugging Python.
212
Antoine Pitrouf83b3082010-03-21 19:19:41 +0000213- Issue #1628484: The Makefile doesn't ignore the CFLAGS environment
214 variable anymore. It also forwards the LDFLAGS settings to the linker
215 when building a shared library.
216
Martin v. Löwis24e4e162010-03-15 13:00:17 +0000217- Issue #6716: Quote -x arguments of compileall in MSI installer.

223
Antoine Pitrou76c86492010-04-01 16:42:11 +0000224- Issue #8276: PyEval_CallObject() is now only available in macro form. The
225 function declaration, which was kept for backwards compatibility reasons,
226 is now removed (the macro was introduced in 1997!).
227
Larry Hastings402b73f2010-03-25 00:54:54 +0000228- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000229 from Python 3.1. All existing Python CObjects in the main distribution
230 have been converted to capsules. To address backwards-compatibility
231 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

421 new members are service_pack_major, service_pack_minor, suite_mask, and
422 product_type.
Eric Smithee931b72010-01-27 00:28:29 +0000423

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

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000476- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000477 file position when calling `truncate()`. It would previously change the file
478 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000479 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000498- Issue #7748: Since unicode values are supported for some metadata options in

500 encoded string for them. This ensures that the upload and register commands
501 send the correct values to PyPI without any error.

575Core and Builtins
576-----------------
577
Georg Brandlba83f822010-03-14 09:50:54 +0000578- The ``__complex__()`` method is now looked up on the class of instances to
579 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000580
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000581- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
582 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
583
Mark Dickinson1b34d252010-01-01 17:27:30 +0000584- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000585 DeprecationWarning when passed a float argument where an integer was expected.
586 These functions and methods now raise TypeError instead. The majority of the
587 effects of this change are in the extension modules, but some core functions
588 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
589 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000602- Issue #1811: Improve accuracy and cross-platform consistency for true division
603 of integers: the result of a/b is now correctly rounded for ints a and b (at
604 least on IEEE 754 platforms), and in particular does not depend on the
605 internal representation of a long.

613
Georg Brandlba83f822010-03-14 09:50:54 +0000614 These executables now work properly with the arch(1) command: ``arch -ppc
615 python`` will start a universal binary version of python in PPC mode (unlike
616 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000772- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
773 decimal string that's guaranteed to round back to x under correct rounding
774 (with round-half-to-even rounding mode). Previously it gave a string based on
775 rounding x to 17 decimal digits. repr(x) for a complex number behaves
776 similarly. On platforms where the correctly-rounded strtod and dtoa code is
777 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +0000779- Issue #7117: On almost all platforms: float-to-string and string-to-float
780 conversions within Python are now correctly rounded. Places these conversions
781 occur include: str for floats and complex numbers; the float and complex
782 constructors; old-style and new-style numeric formatting; serialization and
783 deserialization of floats and complex numbers using marshal, pickle and json;
784 parsing of float and imaginary literals in Python code; Decimal-to-float
785 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000786
Georg Brandlba83f822010-03-14 09:50:54 +0000787 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
788 providing correctly-rounded strtod and dtoa C functions. This code is
789 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
790 the C compiler. There may be a small number of platforms on which correct
791 operation of this code cannot be guaranteed, so the code is not used: notably,
792 this applies to platforms where the C double format is not IEEE 754 binary64,
793 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
794 and Python's configure script is unable to determine how to change the FPU
795 precision. On these platforms conversions use the platform strtod and dtoa,
796 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000798- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
799 uses the correctly-rounded string <-> float conversions described above (when
800 available), and so produces correctly rounded results that will display nicely
801 under the float repr. There are two related small changes: (1) round now
802 accepts any class with an ``__index__()`` method for its second argument (but
803 no longer accepts floats for the second argument), and (2) an excessively
804 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
805 raises an exception.

1184 this code path is really executed because I cannot move to such directory on

1211 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

2387 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2388 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2389 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002588- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2589 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2590 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2591 ``printf`` function, whereas PyString_FromFormat has an independent
2592 implementation and uses "%zd" on all platforms for size_t values.
2593 This makes a difference on win64, where ``printf`` needs "%Id" to display

2600 object; previously an int would be returned for small values. the __long__
2601 method is allowed to return either an int or a long, but the behaviour of

2617 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2618 type object.

2689 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2690 for catch_warnings() also led to an improvement in the raising of a
2691 DeprecationWarning related to warnings.warn_explicit().

2718 without limit.
2719

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002757What's New in Python 2.6 beta 3?
2758================================
2759
Barry Warsaw07a4a382008-08-21 01:15:08 +00002760*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002761
2762Core and Builtins
2763-----------------
2764
Guido van Rossumf8402962008-08-20 15:01:50 +00002765- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2766 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2767 extensions do not automatically benefit from the class attribute
2768 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2769 to their tp_flags field if they care. This is a backwards
2770 compatibility feature; in 3.0, all types will use the cache by
2771 default.
2772
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002773- Keyword arguments can now follow starred arguments. (``f(a, *args,
2774 keyword=23)`` is now valid syntax.)
2775
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002776- ctypes function pointers that are COM methods have a boolean True
2777 value again.
2778
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002779- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2780 by denying s# to parse objects that have a releasebuffer procedure,
2781 and introducing s*.
2782
Georg Brandl1e13ea92008-08-11 09:07:59 +00002783- Issue #3537: Fix an assertion failure when an empty but presized dict
2784 object was stored in the freelist.
2785
Mark Dickinsonb6467572008-08-04 21:30:09 +00002786- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2787 ValueError consistently across platforms.
2788
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002789- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2790 (64bit Unix, for example), unichr() would truncate its argument and return
2791 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2792
Neal Norwitze7d8be82008-07-31 17:17:14 +00002793- Apply security patches from Apple.
2794
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002795- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2796 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2797
Antoine Pitrou92f82162008-07-25 22:22:08 +00002798- Issue #1819: function calls with several named parameters are now on
2799 average 35% faster (as measured by pybench).
2800
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002801- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2802 the python debugger steps into a class statement: the free variables (local
2803 variables defined in an outer scope) would be deleted from the outer scope.
2804
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002805- Issue #2620: Overflow checking when allocating or reallocating memory
2806 was not always being done properly in some python types and extension
2807 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2808 all been updated to perform better checks and places in the code that
2809 would previously leak memory on the error path when such an allocation
2810 failed have been fixed.

2814
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002815- Issue #3612: Added some missing basic types in ctypes.wintypes.
2816
Benjamin Petersone977ad42008-08-20 01:42:01 +00002817- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2818 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2819
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002820- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2821 version reported by these tools does not necessarily follow the python
2822 version numbering scheme, so the module is less strict when parsing it.
2823
Nick Coghlanf70385a2008-08-18 12:42:46 +00002824- Issue #2235: Added Py3k warnings for types which will become unhashable
2825 under the stricter __hash__ inheritance rules in 3.0. Several types
2826 which did not meet the rules for hash invariants and were already
2827 unhashable in 3.0 have now been explicitly flagged as unhashable in
2828 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2829 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2830
Brett Cannon88f801d2008-08-18 00:46:22 +00002831- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2832 imported into the module but exposed as part of the module's API.
2833
Brett Cannon7b96f072008-08-18 00:41:11 +00002834- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2835
Brett Cannon46225e72008-08-18 00:36:52 +00002836- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002838- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2839
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002840- Issue #3575: Incremental decoder's decode function now takes bytearray
2841 by using 's*' instead of 't#'.
2842
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002843- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002844 fails unicode conversion on 2nd parameter. (windows only)
2845
Facundo Batista94f243a2008-08-17 03:38:39 +00002846- Issue 2464. urllib2 now supports a malformation in the URL received
2847 in a redirect.
2848
Brett Cannonabe423e2008-08-16 21:47:07 +00002849- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002850 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002851
Facundo Batistaeb90b782008-08-16 14:44:07 +00002852- Issue #2776: fixed small issue when handling an URL with double slash
2853 after a 302 response in the case of not going through a proxy.
2854
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002855- Issue #2676: in the email package, content-type parsing was hanging on
2856 pathological input because of quadratic or exponential behaviour of a
2857 regular expression.
2858
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002859- Issue #3476: binary buffered reading through the new "io" library is now
2860 thread-safe.
2861
Brett Cannonbf3157b2008-08-14 05:00:03 +00002862- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2863 since mimetools itself is deprecated. Because modules are cached, all
2864 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2865
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002866- Issue #3134: shutil referenced undefined WindowsError symbol.
2867
Robert Schuppenies14646332008-08-10 11:01:53 +00002868- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2869 menu entries were not deleted.
2870
Brett Cannon83e81842008-08-09 23:30:55 +00002871- Copied the implementation of reduce() to _functools.reduce() to have a
2872 version that did not raise a DeprecationWarning under -3.
2873
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002874- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2875 a MemoryError rather than silently stop the iteration.
2876
Guido van Rossum59ce9012008-08-09 14:55:34 +00002877- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2878 to _sre.compile() will now be rejected. This should not affect anybody
2879 since the re.compile() function never generates invalid re-bytecode.
2880
Skip Montanaroa032bf42008-08-08 22:52:51 +00002881- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2882 upon first access it can be automatically initialized from the csv file if
2883 it wasn't initialized during instantiation.
2884
Brett Cannon3aa2a492008-08-06 22:28:09 +00002885- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2886 the reload() built-in has been removed.
2887
Brett Cannon7e30b672008-08-04 21:52:25 +00002888- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002889 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002900 asking for a specific length. This problem only affected files opened
2901 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002902

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002951What's New in Python 2.6 beta 2?
2952================================
2953
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002954*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002956Core and Builtins
2957-----------------
2958
Georg Brandl3e483f62008-07-16 22:57:41 +00002959- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2960 its methods now allow for items objects that can be converted to
2961 an integer using operator.index().
2962
Mark Dickinson64b7e502008-07-16 09:40:03 +00002963- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2964 produced a ValueError instead of giving the correct float.
2965
Eric Smitha5fa5a22008-07-16 00:11:49 +00002966- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2967 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2968
Mark Dickinson7103aa42008-07-15 19:08:33 +00002969- Issue #3008: the float type has a new instance method 'float.hex'
2970 and a new class method 'float.fromhex' to convert floating-point
2971 numbers to and from hexadecimal strings, respectively.
2972
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002973- Issue #2235: __hash__ is once again inherited by default. To allow
2974 collections.Hashable to remain meaningful in the presence of the
2975 default hash implementation (object.__hash__), it is now possible
2976 to explicit block inheritance of hash by setting __hash__=None at
2977 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2978 level.
2979
Nick Coghlanb028f502008-07-13 14:52:36 +00002980- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2981 the parent module cannot be found while performing an absolute import.
2982 This means that an incorrectly defined __package__ attribute will
2983 now only prevent relative imports in that module rather than causing
2984 all imports from that module to fail.
2985
Nick Coghlan14ff9942008-07-08 14:21:42 +00002986- Issue #2517: Allow unicode messages in Exceptions again by correctly
2987 bypassing the instance dictionary when looking up __unicode__ on
2988 new-style classes.

2991 set to a custom object whose write() method happens to install
2992 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002994- Issue #3088: Corrected a race condition in classes derived from
2995 threading.local: the first member set by a thread could be saved in
2996 another thread's dictionary.
2997
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002998- Issue #3004: Minor change to slice.indices(): the start and stop
2999 arguments are now treated identically, making the behaviour easier
3000 to describe and understand. For example, slice(None, -10,
3001 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3002 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3003 10, -1).
3004
Georg Brandl278fc502008-07-19 12:46:12 +00003005- Issue #3219: Calling a function with repeated keyword arguments,
3006 f(a=2, a=23), would not cause a syntax error. This was a regression
3007 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003008
Georg Brandl278fc502008-07-19 12:46:12 +00003009- Issue #2862: Make int and float freelist management consistent with
3010 other freelists. Changes their CompactFreeList apis into
3011 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003016- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3017 api functions without holding the GIL, which could lead to a fatal
3018 error when they failed.
3019
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003020- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003045- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3046 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003047 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003048 content-length. The problem had been corrected in the 2.4 branch, but never
3049 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003064- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3065 handling is now the same as that of other special attributes like __name__).
3066
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003067- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00003519- Issue #1631171: Re-implement the 'warnings' module in C (the
3520 original Python code has been kept as backup). This will allow for
3521 using the 'warning's machinery in such places as the parser where
3522 use of pure Python code is not possible. Both the ``showarning()``
3523 and ``formatwarning()`` gain an optional 'line' argument which is
3524 not called by default for backwards-compatibility reasons. Setting
3525 ``warnings.showwarning()`` to an implementation that lacks support
3526 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003589- Issue #2550: The approach used by client/server code for obtaining
3590 ports to listen on in network-oriented tests has been refined in an
3591 effort to facilitate running multiple instances of the entire
3592 regression test suite in parallel without issue.
3593 test_support.bind_port() has been fixed such that it will always
3594 return a unique port -- which wasn't always the case with the
3595 previous implementation, especially if socket options had been set
3596 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3597 new implementation of bind_port() will actually raise an exception
3598 if it is passed an AF_INET/SOCK_STREAM socket with either the
3599 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3600 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3601 the socket it's been passed. This currently only applies to
3602 Windows. This option prevents any other sockets from binding to the
3603 host/port we've bound to, thus removing the possibility of the
3604 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3605 when a second SOCK_STREAM socket binds and accepts to a host/port
3606 that's already been bound by another socket. The optional preferred
3607 port parameter to bind_port() has been removed. Under no
3608 circumstances should tests be hard coding ports!
3609
3610 test_support.find_unused_port() has also been introduced, which will
3611 pass a temporary socket object to bind_port() in order to obtain an
3612 unused port. The temporary socket object is then closed and
3613 deleted, and the port is returned. This method should only be used
3614 for obtaining an unused port in order to pass to an external program
3615 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3616 a parameter to a server-oriented class that doesn't give you direct
3617 access to the underlying socket used.
3618
3619 Finally, test_support.HOST has been introduced, which should be used
3620 for the host argument of any relevant socket calls (i.e. bind and
3621 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003622
3623 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003624 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003625 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3626 test_asynchat and test_socket_ssl.
3627
Georg Brandl3ee81df2008-05-17 18:14:43 +00003628 It is now possible for multiple instances of the regression test
3629 suite to run in parallel without issue.

3897
Fred Drakea8ee94b2008-03-01 02:45:07 +00003898- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003899 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003904
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003905- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003906 issue 215555 for a discussion.
3907
Eric Smitha73fbe72008-02-23 03:09:44 +00003908- Added the future_builtins module, which contains hex() and oct().
3909 These are the PEP 3127 version of these functions, designed to be
3910 compatible with the hex() and oct() builtins from Python 3.0. They
3911 differ slightly in their output formats from the existing, unchanged
3912 Python 2.6 builtins. The expected usage of the future_builtins
3913 module is:
3914 from future_builtins import hex, oct
3915
Eric Smith7ef40bf2008-02-20 23:34:22 +00003916- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3917 exponents for exponents with absolute value < 100. Follows C99
3918 standard. This is a change on Windows, which would use 3 digits.
3919 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3920 so that any alterations it does to the resulting string will be
3921 available in stringlib/formatter.h (for float.__format__).
3922
Eric Smith5a3c1352008-02-19 13:21:56 +00003923- Implemented PEP 3101, Advanced String Formatting. This adds a new
3924 builtin format(); a format() method for str and unicode; a
3925 __format__() method to object, str, unicode, int, long, float, and
3926 datetime; the class string.Formatter; and the C API
3927 PyObject_Format().
3928
Georg Brandl3ee81df2008-05-17 18:14:43 +00003929- Fixed several potential crashes, all caused by specially crafted
3930 __del__ methods exploiting objects in temporarily inconsistent
3931 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003932
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003933- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003934 prevent a possible crash: an Abstract Base Class would try to access
3935 a slot on a registered virtual subclass.

3942 memory to the OS earlier.

3946 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003947

3955 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003956 to compact the internal free lists of pre-allocted ints and floats.
3957
Georg Brandl3ee81df2008-05-17 18:14:43 +00003958- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3959 calls. Python expected the return type int but the fork familie
3960 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003974- Patch #1473257: generator objects gain a gi_code attribute. This is
3975 the same object as the func_code attribute of the function that
3976 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003977
Georg Brandl3ee81df2008-05-17 18:14:43 +00003978- Issue #1920: "while 0" statements were completely removed by the
3979 compiler, even in the presence of an "else" clause, which is
3980 supposed to be run when the condition is false. Now the compiler
3981 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003982

Georg Brandl6caad7d2008-01-26 14:19:22 +00004000- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004001 added.
4002
Christian Heimesc94e2b52008-01-14 04:13:37 +00004003- sys.float_info / PyFloat_GetInfo: The floating point information
4004 object was converted from a dict to a specialized structseq object.
4005
Georg Brandl3ee81df2008-05-17 18:14:43 +00004006- Patch #1816: Added sys.flags structseq. It exposes the status of
4007 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004008
Georg Brandl3ee81df2008-05-17 18:14:43 +00004009- Objects/structseq.c: Implemented new structseq representation. The
4010 patch makes structseqs (e.g. the return value of os.stat) more
4011 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004012
Georg Brandl3ee81df2008-05-17 18:14:43 +00004013- Patch #1700288: added a type attribute cache that caches method
4014 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004015
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004016- Bug #1776: __import__() no longer accepts filenames on any platform.
4017 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004018
Georg Brandlaed6c662008-01-07 17:25:53 +00004019- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4020
Georg Brandl3ee81df2008-05-17 18:14:43 +00004021- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4022 envvar and sys.dont_write_bytecode attribute. All these can be set
4023 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004024
Georg Brandl3ee81df2008-05-17 18:14:43 +00004025- Improve some exception messages when Windows fails to load an
4026 extension module. Now we get for example '%1 is not a valid Win32
4027 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004028

Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4032 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004033
Christian Heimes0a8143f2007-12-18 23:22:54 +00004034- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004035 and INF. float("nan"), float("inf") and float("-inf") now work on
4036 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004037
Georg Brandl3ee81df2008-05-17 18:14:43 +00004038- Compiler now generates simpler and faster code for dictionary
4039 literals. The oparg for BUILD_MAP now indicates an estimated
4040 dictionary size. There is a new opcode, STORE_MAP, for adding
4041 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004070- Patch #1739468: Directories and zipfiles containing a __main__.py
4071 file can now be directly executed by passing their name to the
4072 interpreter. The directory/zipfile is automatically inserted as the
4073 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004074
Georg Brandl3ee81df2008-05-17 18:14:43 +00004075- Issue #1265: Fix a problem with sys.settrace, if the tracing
4076 function uses a generator expression when at the same time the
4077 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004078
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004079- sets and frozensets now have an isdisjoint() method.
4080

4082
Neal Norwitz44f326e2007-10-05 05:29:17 +00004083- Fix warnings found by the new version of the Coverity checker.
4084
Georg Brandl21e99f42010-03-07 15:23:59 +00004085- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004086 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4087 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004088
Georg Brandl3ee81df2008-05-17 18:14:43 +00004089- Issue #1686386: Tuple's tp_repr did not take into account the
4090 possibility of having a self-referential tuple, which is possible
4091 from C code. Nor did object's tp_str consider that a type's tp_str
4092 could do something that could lead to an inifinite recursion.
4093 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4094 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004095
Georg Brandl3ee81df2008-05-17 18:14:43 +00004096- Issue #1164: It was possible to trigger deadlock when using the
4097 'print' statement to write to a file since the GIL was not released
4098 as needed. Now PyObject_Print() does the right thing along with
4099 various tp_print implementations of the built-in types and those in
4100 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004101
Georg Brandl3ee81df2008-05-17 18:14:43 +00004102- Issue #1147: Exceptions were directly allowing string exceptions in
4103 their throw() method even though string exceptions no longer
4104 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004105
Georg Brandl3ee81df2008-05-17 18:14:43 +00004106- Issue #1096: Prevent a segfault from getting the repr of a very
4107 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004108
Brett Cannon1e534b52007-09-07 04:18:30 +00004109- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004110 PyObject_Call() never calling back out to Python code to trigger
4111 recursion depth updates/checks. Required the creation of a static
4112 RuntimeError instance in case normalizing an exception put the
4113 recursion check value past its limit. Fixes crashers
4114 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004115

Neal Norwitz0ac60192007-05-27 04:08:54 +00004129- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004130 __*__ attributes. (Some already existed, e.g., __doc__ and
4131 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004132
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004133- Add -3 option to the interpreter to warn about features that are
4134 deprecated and will be changed/removed in Python 3.0.
4135
Georg Brandl2134e752007-05-21 20:34:16 +00004136- Patch #1686487: you can now pass any mapping after '**' in function
4137 calls.
4138
Collin Winter62903052007-05-18 23:11:24 +00004139- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004140 "except E as target:". This is to provide forwards compatibility
4141 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004142
Brett Cannon229cee22007-05-05 01:34:02 +00004143- Deprecate BaseException.message as per PEP 352.
4144
Georg Brandl3ee81df2008-05-17 18:14:43 +00004145- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004146 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004147
Vinay Sajip8549ce32007-05-06 17:53:37 +00004148- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004149 setting a plain string, ie don't expand to single letter identifiers.
4150
Raymond Hettinger13936692007-04-11 18:40:58 +00004151- Request #1191699: Slices can now be pickled.
4152
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004153- Request #1193128: str.translate() now allows a None argument for
4154 translations that only remove characters without re-mapping the
4155 remaining characters.
4156
Georg Brandl5cb76c12007-03-21 09:00:39 +00004157- Patch #1682205: a TypeError while unpacking an iterable is no longer
4158 masked by a generic one with the message "unpack non-sequence".
4159
Neal Norwitzaa754b72007-03-21 06:39:48 +00004160- Remove unused file Python/fmod.c.
4161
Guido van Rossum143b5642007-03-23 04:58:42 +00004162- Bug #1683368: The object.__init__() and object.__new__() methods are
4163 now stricter in rejecting excess arguments. The only time when
4164 either allows excess arguments is when it is not overridden and the
4165 other one is. For backwards compatibility, when both are
4166 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004167 warning later). Also, type.__init__() insists on the same signature
4168 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004169
Georg Brandl3ee81df2008-05-17 18:14:43 +00004170- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4171 object to complex using its __complex__() method before falling back
4172 to the __float__() method. Therefore, the functions in the cmath
4173 module now can operate on objects that define a __complex__()
4174 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004175
Georg Brandl3ee81df2008-05-17 18:14:43 +00004176- Patch #1623563: allow __class__ assignment for classes with
4177 __slots__. The old and the new class are still required to have the
4178 same slot names.

4184 ``object.__reduce_ex__()`` is called with an object that is faking
4185 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004186
Georg Brandl3ee81df2008-05-17 18:14:43 +00004187- Patch #1680015: Don't modify __slots__ tuple if it contains an

4191
Georg Brandl7b9c5552007-03-12 14:30:05 +00004192- Bug #1678647: write a newline after printing an exception in any
4193 case, even when converting the value to a string failed.
4194
Georg Brandl871f1bc2007-03-12 13:17:36 +00004195- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196 its argument, if it exists. If not, it will work like before. This
4197 allows customizing the output of dir() in the presence of a
4198 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004199
Collin Winter276887b2007-03-12 16:11:39 +00004200- Patch #922167: Python no longer segfaults when faced with infinitely
4201 self-recursive reload() calls (as reported by bug #742342).
4202
Georg Brandl3ee81df2008-05-17 18:14:43 +00004203- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004206- Patch #1491866: change the complex() constructor to allow
4207 parthensized forms. This means complex(repr(x)) now works instead of
4208 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004209
Georg Brandlaa2321b2007-03-07 00:40:28 +00004210- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004211 makes the filenames the warning module prints much more sensible
4212 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004213
Georg Brandl49aafc92007-03-07 00:34:46 +00004214- Variant of patch #697613: don't exit the interpreter on a SystemExit
4215 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004216 variable is given, but break into the interactive interpreter just
4217 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004225- Patch #1674228: when assigning a slice (old-style), check for the
4226 sq_ass_slice instead of the sq_slice slot.
4227
Georg Brandl3ee81df2008-05-17 18:14:43 +00004228- When printing an unraisable error, don't print exceptions. before
4229 the name. This duplicates the behavior whening normally printing
4230 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004231

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004732- Added a timeout parameter to the constructor of other protocols
4733 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4734 work started with create_connection() and timeout in httplib, and
4735 closes patch #723312.
4736
Vinay Sajip8549ce32007-05-06 17:53:37 +00004737- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00004763 AttributeError instead of an IOError when the server's response
4764 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004765

Georg Brandl3ee81df2008-05-17 18:14:43 +00004770- Patch #1429539: pdb now correctly initializes the __main__ module
4771 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004772 correctly now.
4773

Georg Brandl3ee81df2008-05-17 18:14:43 +00004781- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00004794- Patch #1581073: add a flag to textwrap that prevents the dropping of

4796
Georg Brandl92a6bae2007-03-13 17:43:32 +00004797- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004798 are set for invalid interpolation sequences that would lead to
4799 errors on reading back those values.

4842 returned string up to the first NUL character.

4853
Georg Brandl3ee81df2008-05-17 18:14:43 +00004854- unittest now verifies more of its assumptions. In particular,
4855 TestCase and TestSuite subclasses (not instances) are no longer
4856 accepted in TestSuite.addTest(). This should cause no
4857 incompatibility since it never made sense with ordinary subclasses
4858 -- the failure just occurred later, with a more cumbersome
4859 exception.

4869
Georg Brandl3ee81df2008-05-17 18:14:43 +00004870- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00005248 time so that opening a database previously created with the DB_DUP
5249 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5250 opens. Specifically: dictionary assignment to a DB object will
5251 replace all values for a given key when the database allows
5252 duplicate values. DB users should use DB.put(k, v) when they want
5253 to store duplicates; not DB[k] = v.

5260 characters with ASCII value less than 32. Also, it correctly quotes
5261 dots only if they occur on a single line, as opposed to the previous
5262 behavior of quoting dots if they are the second character of any
5263 line.
