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.

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
Mark Dickinson7c63eee2010-04-02 22:27:36 +000060- Issue #8294: The Fraction constructor now accepts Decimal and float
61 instances directly.
62
Mark Dickinsone096e822010-04-02 10:17:07 +000063- Issue #7279: Comparisons involving a Decimal signaling NaN now
64 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000065 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
66 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000067
Mark Dickinson99d80962010-04-02 08:53:22 +000068- Issue #2531: Comparison operations between floats and Decimal
69 instances now return a result based on the numeric values of the
70 operands; previously they returned an arbitrary result based on
71 the relative ordering of id(float) and id(Decimal).
72
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000073- Issue #8233: When run as a script, py_compile.py optionally takes a single
74 argument `-` which tells it to read files to compile from stdin. Each line
75 is read on demand and the named file is compiled immediately. (Original
76 patch by Piotr Ożarowski).
77
78- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
79 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000080
Florent Xicluna58b65662010-03-30 16:29:03 +000081- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
82 form feed (0x0C) are now considered linebreaks, as specified in Unicode
83 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +000084 http://www.unicode.org/reports/tr14/
85
Mark Dickinson9588d992010-03-27 11:14:37 +000086- Comparisons using one of <, <=, >, >= between a complex instance and
87 a Fractions instance now raise TypeError instead of returning
88 True/False. This makes Fraction <=> complex comparisons consistent with
89 int <=> complex, float <=> complex, and complex <=> complex comparisons.
90
Michael Foorde6410c52010-03-29 20:04:23 +000091- Addition of ``WeakSet`` to the ``weakref`` module.
92
Vinay Sajipb0623d62010-03-24 14:31:21 +000093- logging: Added LOG_FTP to SysLogHandler and updated documentation.
94
Florent Xicluna176cda12010-03-22 22:52:11 +000095- Issue #8205: Remove the "Modules" directory from sys.path when Python is
96 running from the build directory (POSIX only).
97
Florent Xiclunae1f4c922010-03-22 22:45:50 +000098- Issue #7667: Fix doctest failures with non-ASCII paths.
99
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000100- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
101 didn't support chflags() (for example ZFS under FreeBSD). The error is
102 now silenced.
103
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000104- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
105 deprecated.
106
R. David Murrayc9d1a782010-03-22 15:55:09 +0000107- Issue #7860: platform.uname now reports the correct 'machine' type
108 when Python is running in WOW64 mode on 64 bit Windows.
109
Vinay Sajip804899b2010-03-22 15:29:01 +0000110- logging: Added getChild utility method to Logger and added isEnabledFor
111 method to LoggerAdapter.
112
Vinay Sajip31e928e2010-03-22 13:02:28 +0000113- Issue #8201: logging: Handle situation of non-ASCII and Unicode
114 logger names existing at the same time, causing a Unicode error
115 when configuration code attempted to sort the existing loggers.
116
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000117- Issue #8200: logging: Handle errors when multiprocessing is not
118 fully loaded when logging occurs.
119
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000120- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
121 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
122 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000123
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000124- Issue #8179: Fix macpath.realpath() on a non-existing path.
125
Florent Xicluna2e0a53f2010-03-18 21:50:06 +0000126- Issue #8024: Update the Unicode database to 5.2.
127
Antoine Pitroud7b731d2010-03-17 22:45:39 +0000128- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support
129 writing into objects supporting the new buffer API, for example bytearrays
130 or memoryviews.
131
Matthias Klose8b411682010-03-16 10:48:52 +0000132- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
133 with Tcl/Tk-8.5.
134
Matthias Kloseb13d04c2010-03-15 17:44:12 +0000135- Issue #8140: extend compileall to compile single files. Add -i option.
136
Matthias Klose358e7ff2010-03-15 13:42:23 +0000137- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
138 the locale.
139
Georg Brandlba83f822010-03-14 09:50:54 +0000140- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000141 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000142 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000143
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000144- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000145 for ``TimedRotatingFileHandler`` by using the modification time of an
146 existing log file to compute the next rollover time. If the log file does
147 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000148
Georg Brandlba83f822010-03-14 09:50:54 +0000149- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

153
Georg Brandlba83f822010-03-14 09:50:54 +0000154- Issue #7624: Fix ``isinstance(foo(), collections.Callable)`` for old-style
Florent Xicluna47627d52010-03-08 15:20:28 +0000155 classes.
156
Georg Brandlba83f822010-03-14 09:50:54 +0000157- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
158 a base64 transfer-encoded payload *after* decoding it; it no longer does.
159 This is a behavior change, so email's minor version number is now bumped, to
160 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000161
Larry Hastings3b958e32010-04-02 11:18:17 +0000162- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is

Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000176- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
177
Jesus Cea6557aac2010-03-22 14:22:26 +0000178- Issue #8156: bsddb module updated to version 4.8.4.
179 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
180 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000181

183
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000184- Issue #8300: When passing a non-integer argument to struct.pack with any
185 integer format code, struct.pack first attempts to convert the non-integer
186 using its __index__ method. If that method is non-existent or raises
187 TypeError it goes on to try the __int__ method, as described below.
188
Georg Brandlba83f822010-03-14 09:50:54 +0000189- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
190 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
191 argument's __int__ method to convert to an integer before packing. It also
192 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
193 was inconsistent: __int__ was used for some integer codes but not for others,
194 and the set of integer codes for which it was used differed between native
195 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000196
Brian Curtin19479fa2010-04-02 21:51:37 +0000197- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a
198 bug in the return value of QueryReflectionKey.

202
Georg Brandlba83f822010-03-14 09:50:54 +0000203- Issue #7993: Add a test of IO packet processing bandwidth to ccbench. It
204 measures the number of UDP packets processed per second depending on the
205 number of background CPU-bound Python threads.
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000206
Collin Wintera70f3492010-03-19 00:08:44 +0000207- python-config now supports multiple options on the same command line.

Martin v. Löwisbf0dfb32010-04-01 07:40:51 +0000212- Issue #8032: For gdb7, a python-gdb.py file is added to the build,
213 allowing to use advanced gdb features when debugging Python.
214
Antoine Pitrouf83b3082010-03-21 19:19:41 +0000215- Issue #1628484: The Makefile doesn't ignore the CFLAGS environment
216 variable anymore. It also forwards the LDFLAGS settings to the linker
217 when building a shared library.
218
Martin v. Löwis24e4e162010-03-15 13:00:17 +0000219- Issue #6716: Quote -x arguments of compileall in MSI installer.

225
Antoine Pitrou76c86492010-04-01 16:42:11 +0000226- Issue #8276: PyEval_CallObject() is now only available in macro form. The
227 function declaration, which was kept for backwards compatibility reasons,
228 is now removed (the macro was introduced in 1997!).
229
Larry Hastings402b73f2010-03-25 00:54:54 +0000230- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000231 from Python 3.1. All existing Python CObjects in the main distribution
232 have been converted to capsules. To address backwards-compatibility
233 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

422 and add the additional members returned in an OSVERSIONINFOEX structure. The
423 new members are service_pack_major, service_pack_minor, suite_mask, and
424 product_type.
Eric Smithee931b72010-01-27 00:28:29 +0000425

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

Antoine Pitroud840e512010-02-04 20:20:18 +0000471- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000472 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000473 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000478- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000479 file position when calling `truncate()`. It would previously change the file
480 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000481 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000500- Issue #7748: Since unicode values are supported for some metadata options in
501 Distutils, the DistributionMetadata get_* methods will now return an utf-8
502 encoded string for them. This ensures that the upload and register commands
503 send the correct values to PyPI without any error.

577Core and Builtins
578-----------------
579
Georg Brandlba83f822010-03-14 09:50:54 +0000580- The ``__complex__()`` method is now looked up on the class of instances to
581 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000582
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000583- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
584 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
585
Mark Dickinson1b34d252010-01-01 17:27:30 +0000586- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000587 DeprecationWarning when passed a float argument where an integer was expected.
588 These functions and methods now raise TypeError instead. The majority of the
589 effects of this change are in the extension modules, but some core functions
590 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
591 and many unicode/str methods.

603
Georg Brandlba83f822010-03-14 09:50:54 +0000604- Issue #1811: Improve accuracy and cross-platform consistency for true division
605 of integers: the result of a/b is now correctly rounded for ints a and b (at
606 least on IEEE 754 platforms), and in particular does not depend on the
607 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000608
Georg Brandlba83f822010-03-14 09:50:54 +0000609- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

615
Georg Brandlba83f822010-03-14 09:50:54 +0000616 These executables now work properly with the arch(1) command: ``arch -ppc
617 python`` will start a universal binary version of python in PPC mode (unlike
618 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000619
Georg Brandlba83f822010-03-14 09:50:54 +0000620- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

Georg Brandlba83f822010-03-14 09:50:54 +0000774- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
775 decimal string that's guaranteed to round back to x under correct rounding
776 (with round-half-to-even rounding mode). Previously it gave a string based on
777 rounding x to 17 decimal digits. repr(x) for a complex number behaves
778 similarly. On platforms where the correctly-rounded strtod and dtoa code is
779 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +0000781- Issue #7117: On almost all platforms: float-to-string and string-to-float
782 conversions within Python are now correctly rounded. Places these conversions
783 occur include: str for floats and complex numbers; the float and complex
784 constructors; old-style and new-style numeric formatting; serialization and
785 deserialization of floats and complex numbers using marshal, pickle and json;
786 parsing of float and imaginary literals in Python code; Decimal-to-float
787 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000788
Georg Brandlba83f822010-03-14 09:50:54 +0000789 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
790 providing correctly-rounded strtod and dtoa C functions. This code is
791 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
792 the C compiler. There may be a small number of platforms on which correct
793 operation of this code cannot be guaranteed, so the code is not used: notably,
794 this applies to platforms where the C double format is not IEEE 754 binary64,
795 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
796 and Python's configure script is unable to determine how to change the FPU
797 precision. On these platforms conversions use the platform strtod and dtoa,
798 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000800- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
801 uses the correctly-rounded string <-> float conversions described above (when
802 available), and so produces correctly rounded results that will display nicely
803 under the float repr. There are two related small changes: (1) round now
804 accepts any class with an ``__index__()`` method for its second argument (but
805 no longer accepts floats for the second argument), and (2) an excessively
806 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
807 raises an exception.

1157
Georg Brandlba83f822010-03-14 09:50:54 +00001158- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on

1186 this code path is really executed because I cannot move to such directory on

1213 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

2389 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2390 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2391 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002590- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2591 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2592 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2593 ``printf`` function, whereas PyString_FromFormat has an independent
2594 implementation and uses "%zd" on all platforms for size_t values.
2595 This makes a difference on win64, where ``printf`` needs "%Id" to display

2602 object; previously an int would be returned for small values. the __long__
2603 method is allowed to return either an int or a long, but the behaviour of

2619 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2620 type object.

2691 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2692 for catch_warnings() also led to an improvement in the raising of a
2693 DeprecationWarning related to warnings.warn_explicit().

2720 without limit.
2721

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002759What's New in Python 2.6 beta 3?
2760================================
2761
Barry Warsaw07a4a382008-08-21 01:15:08 +00002762*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002763
2764Core and Builtins
2765-----------------
2766
Guido van Rossumf8402962008-08-20 15:01:50 +00002767- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2768 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2769 extensions do not automatically benefit from the class attribute
2770 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2771 to their tp_flags field if they care. This is a backwards
2772 compatibility feature; in 3.0, all types will use the cache by
2773 default.
2774
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002775- Keyword arguments can now follow starred arguments. (``f(a, *args,
2776 keyword=23)`` is now valid syntax.)
2777
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002778- ctypes function pointers that are COM methods have a boolean True
2779 value again.
2780
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002781- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2782 by denying s# to parse objects that have a releasebuffer procedure,
2783 and introducing s*.
2784
Georg Brandl1e13ea92008-08-11 09:07:59 +00002785- Issue #3537: Fix an assertion failure when an empty but presized dict
2786 object was stored in the freelist.
2787
Mark Dickinsonb6467572008-08-04 21:30:09 +00002788- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2789 ValueError consistently across platforms.
2790
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002791- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2792 (64bit Unix, for example), unichr() would truncate its argument and return
2793 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2794
Neal Norwitze7d8be82008-07-31 17:17:14 +00002795- Apply security patches from Apple.
2796
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002797- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2798 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2799
Antoine Pitrou92f82162008-07-25 22:22:08 +00002800- Issue #1819: function calls with several named parameters are now on
2801 average 35% faster (as measured by pybench).
2802
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002803- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2804 the python debugger steps into a class statement: the free variables (local
2805 variables defined in an outer scope) would be deleted from the outer scope.
2806
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002807- Issue #2620: Overflow checking when allocating or reallocating memory
2808 was not always being done properly in some python types and extension
2809 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2810 all been updated to perform better checks and places in the code that
2811 would previously leak memory on the error path when such an allocation
2812 failed have been fixed.

2816
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002817- Issue #3612: Added some missing basic types in ctypes.wintypes.
2818
Benjamin Petersone977ad42008-08-20 01:42:01 +00002819- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2820 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2821
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002822- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2823 version reported by these tools does not necessarily follow the python
2824 version numbering scheme, so the module is less strict when parsing it.
2825
Nick Coghlanf70385a2008-08-18 12:42:46 +00002826- Issue #2235: Added Py3k warnings for types which will become unhashable
2827 under the stricter __hash__ inheritance rules in 3.0. Several types
2828 which did not meet the rules for hash invariants and were already
2829 unhashable in 3.0 have now been explicitly flagged as unhashable in
2830 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2831 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2832
Brett Cannon88f801d2008-08-18 00:46:22 +00002833- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2834 imported into the module but exposed as part of the module's API.
2835
Brett Cannon7b96f072008-08-18 00:41:11 +00002836- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2837
Brett Cannon46225e72008-08-18 00:36:52 +00002838- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002840- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2841
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002842- Issue #3575: Incremental decoder's decode function now takes bytearray
2843 by using 's*' instead of 't#'.
2844
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002845- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002846 fails unicode conversion on 2nd parameter. (windows only)
2847
Facundo Batista94f243a2008-08-17 03:38:39 +00002848- Issue 2464. urllib2 now supports a malformation in the URL received
2849 in a redirect.
2850
Brett Cannonabe423e2008-08-16 21:47:07 +00002851- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002852 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002853
Facundo Batistaeb90b782008-08-16 14:44:07 +00002854- Issue #2776: fixed small issue when handling an URL with double slash
2855 after a 302 response in the case of not going through a proxy.
2856
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002857- Issue #2676: in the email package, content-type parsing was hanging on
2858 pathological input because of quadratic or exponential behaviour of a
2859 regular expression.
2860
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002861- Issue #3476: binary buffered reading through the new "io" library is now
2862 thread-safe.
2863
Brett Cannonbf3157b2008-08-14 05:00:03 +00002864- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2865 since mimetools itself is deprecated. Because modules are cached, all
2866 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2867
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002868- Issue #3134: shutil referenced undefined WindowsError symbol.
2869
Robert Schuppenies14646332008-08-10 11:01:53 +00002870- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2871 menu entries were not deleted.
2872
Brett Cannon83e81842008-08-09 23:30:55 +00002873- Copied the implementation of reduce() to _functools.reduce() to have a
2874 version that did not raise a DeprecationWarning under -3.
2875
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002876- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2877 a MemoryError rather than silently stop the iteration.
2878
Guido van Rossum59ce9012008-08-09 14:55:34 +00002879- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2880 to _sre.compile() will now be rejected. This should not affect anybody
2881 since the re.compile() function never generates invalid re-bytecode.
2882
Skip Montanaroa032bf42008-08-08 22:52:51 +00002883- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2884 upon first access it can be automatically initialized from the csv file if
2885 it wasn't initialized during instantiation.
2886
Brett Cannon3aa2a492008-08-06 22:28:09 +00002887- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2888 the reload() built-in has been removed.
2889
Brett Cannon7e30b672008-08-04 21:52:25 +00002890- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002891 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002902 asking for a specific length. This problem only affected files opened
2903 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002904

2959-----------------
2960
Georg Brandl3e483f62008-07-16 22:57:41 +00002961- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2962 its methods now allow for items objects that can be converted to
2963 an integer using operator.index().
2964
Mark Dickinson64b7e502008-07-16 09:40:03 +00002965- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2966 produced a ValueError instead of giving the correct float.
2967
Eric Smitha5fa5a22008-07-16 00:11:49 +00002968- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2969 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2970
Mark Dickinson7103aa42008-07-15 19:08:33 +00002971- Issue #3008: the float type has a new instance method 'float.hex'
2972 and a new class method 'float.fromhex' to convert floating-point
2973 numbers to and from hexadecimal strings, respectively.
2974
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002975- Issue #2235: __hash__ is once again inherited by default. To allow
2976 collections.Hashable to remain meaningful in the presence of the
2977 default hash implementation (object.__hash__), it is now possible
2978 to explicit block inheritance of hash by setting __hash__=None at
2979 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2980 level.
2981
Nick Coghlanb028f502008-07-13 14:52:36 +00002982- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2983 the parent module cannot be found while performing an absolute import.
2984 This means that an incorrectly defined __package__ attribute will
2985 now only prevent relative imports in that module rather than causing
2986 all imports from that module to fail.
2987
Nick Coghlan14ff9942008-07-08 14:21:42 +00002988- Issue #2517: Allow unicode messages in Exceptions again by correctly

2993 set to a custom object whose write() method happens to install
2994 another file in sys.stdout.

2997 threading.local: the first member set by a thread could be saved in
2998 another thread's dictionary.
2999
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003000- Issue #3004: Minor change to slice.indices(): the start and stop
3001 arguments are now treated identically, making the behaviour easier
3002 to describe and understand. For example, slice(None, -10,
3003 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3004 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3005 10, -1).
3006
Georg Brandl278fc502008-07-19 12:46:12 +00003007- Issue #3219: Calling a function with repeated keyword arguments,
3008 f(a=2, a=23), would not cause a syntax error. This was a regression
3009 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003010
Georg Brandl278fc502008-07-19 12:46:12 +00003011- Issue #2862: Make int and float freelist management consistent with
3012 other freelists. Changes their CompactFreeList apis into
3013 ClearFreeList apis and calls them via gc.collect().

3019 api functions without holding the GIL, which could lead to a fatal
3020 error when they failed.
3021
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003022- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003047- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3048 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003049 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003050 content-length. The problem had been corrected in the 2.4 branch, but never
3051 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003066- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3067 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003521- Issue #1631171: Re-implement the 'warnings' module in C (the
3522 original Python code has been kept as backup). This will allow for
3523 using the 'warning's machinery in such places as the parser where
3524 use of pure Python code is not possible. Both the ``showarning()``
3525 and ``formatwarning()`` gain an optional 'line' argument which is
3526 not called by default for backwards-compatibility reasons. Setting
3527 ``warnings.showwarning()`` to an implementation that lacks support
3528 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003591- Issue #2550: The approach used by client/server code for obtaining
3592 ports to listen on in network-oriented tests has been refined in an
3593 effort to facilitate running multiple instances of the entire
3594 regression test suite in parallel without issue.
3595 test_support.bind_port() has been fixed such that it will always
3596 return a unique port -- which wasn't always the case with the
3597 previous implementation, especially if socket options had been set
3598 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3599 new implementation of bind_port() will actually raise an exception
3600 if it is passed an AF_INET/SOCK_STREAM socket with either the
3601 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3602 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3603 the socket it's been passed. This currently only applies to
3604 Windows. This option prevents any other sockets from binding to the
3605 host/port we've bound to, thus removing the possibility of the
3606 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3607 when a second SOCK_STREAM socket binds and accepts to a host/port
3608 that's already been bound by another socket. The optional preferred
3609 port parameter to bind_port() has been removed. Under no
3610 circumstances should tests be hard coding ports!
3611
3612 test_support.find_unused_port() has also been introduced, which will
3613 pass a temporary socket object to bind_port() in order to obtain an
3614 unused port. The temporary socket object is then closed and
3615 deleted, and the port is returned. This method should only be used
3616 for obtaining an unused port in order to pass to an external program
3617 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3618 a parameter to a server-oriented class that doesn't give you direct
3619 access to the underlying socket used.
3620
3621 Finally, test_support.HOST has been introduced, which should be used
3622 for the host argument of any relevant socket calls (i.e. bind and
3623 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003624
3625 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003626 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003627 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3628 test_asynchat and test_socket_ssl.
3629
Georg Brandl3ee81df2008-05-17 18:14:43 +00003630 It is now possible for multiple instances of the regression test
3631 suite to run in parallel without issue.

3899
Fred Drakea8ee94b2008-03-01 02:45:07 +00003900- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003901 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003906
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003907- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003908 issue 215555 for a discussion.
3909
Eric Smitha73fbe72008-02-23 03:09:44 +00003910- Added the future_builtins module, which contains hex() and oct().
3911 These are the PEP 3127 version of these functions, designed to be
3912 compatible with the hex() and oct() builtins from Python 3.0. They
3913 differ slightly in their output formats from the existing, unchanged
3914 Python 2.6 builtins. The expected usage of the future_builtins
3915 module is:
3916 from future_builtins import hex, oct
3917
Eric Smith7ef40bf2008-02-20 23:34:22 +00003918- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3919 exponents for exponents with absolute value < 100. Follows C99
3920 standard. This is a change on Windows, which would use 3 digits.
3921 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3922 so that any alterations it does to the resulting string will be
3923 available in stringlib/formatter.h (for float.__format__).
3924
Eric Smith5a3c1352008-02-19 13:21:56 +00003925- Implemented PEP 3101, Advanced String Formatting. This adds a new
3926 builtin format(); a format() method for str and unicode; a
3927 __format__() method to object, str, unicode, int, long, float, and
3928 datetime; the class string.Formatter; and the C API
3929 PyObject_Format().
3930
Georg Brandl3ee81df2008-05-17 18:14:43 +00003931- Fixed several potential crashes, all caused by specially crafted
3932 __del__ methods exploiting objects in temporarily inconsistent
3933 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003934
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003935- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003936 prevent a possible crash: an Abstract Base Class would try to access
3937 a slot on a registered virtual subclass.

3943 in order to allow pymalloc to free more arenas. Python may give back
3944 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003945
Georg Brandl3ee81df2008-05-17 18:14:43 +00003946- Issue #2045: Fix an infinite recursion triggered when printing a

3948 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003949
Christian Heimesf75dbef2008-02-08 00:11:31 +00003950- Fixed a minor memory leak in dictobject.c. The content of the free
3951 list was not freed on interpreter shutdown.
3952
Georg Brandl21e99f42010-03-07 15:23:59 +00003953- Limit free list of method and built-in function objects to 256

3957 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003958 to compact the internal free lists of pre-allocted ints and floats.
3959
Georg Brandl3ee81df2008-05-17 18:14:43 +00003960- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3961 calls. Python expected the return type int but the fork familie
3962 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003976- Patch #1473257: generator objects gain a gi_code attribute. This is
3977 the same object as the func_code attribute of the function that
3978 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003979
Georg Brandl3ee81df2008-05-17 18:14:43 +00003980- Issue #1920: "while 0" statements were completely removed by the
3981 compiler, even in the presence of an "else" clause, which is
3982 supposed to be run when the condition is false. Now the compiler
3983 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003984

Georg Brandl6caad7d2008-01-26 14:19:22 +00004002- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004003 added.
4004
Christian Heimesc94e2b52008-01-14 04:13:37 +00004005- sys.float_info / PyFloat_GetInfo: The floating point information
4006 object was converted from a dict to a specialized structseq object.
4007
Georg Brandl3ee81df2008-05-17 18:14:43 +00004008- Patch #1816: Added sys.flags structseq. It exposes the status of
4009 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004010
Georg Brandl3ee81df2008-05-17 18:14:43 +00004011- Objects/structseq.c: Implemented new structseq representation. The
4012 patch makes structseqs (e.g. the return value of os.stat) more
4013 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004014
Georg Brandl3ee81df2008-05-17 18:14:43 +00004015- Patch #1700288: added a type attribute cache that caches method
4016 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004017
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004018- Bug #1776: __import__() no longer accepts filenames on any platform.
4019 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004020
Georg Brandlaed6c662008-01-07 17:25:53 +00004021- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4022
Georg Brandl3ee81df2008-05-17 18:14:43 +00004023- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4024 envvar and sys.dont_write_bytecode attribute. All these can be set
4025 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004026
Georg Brandl3ee81df2008-05-17 18:14:43 +00004027- Improve some exception messages when Windows fails to load an
4028 extension module. Now we get for example '%1 is not a valid Win32
4029 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004030
Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004033- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4034 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004035
Christian Heimes0a8143f2007-12-18 23:22:54 +00004036- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004037 and INF. float("nan"), float("inf") and float("-inf") now work on
4038 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004039
Georg Brandl3ee81df2008-05-17 18:14:43 +00004040- Compiler now generates simpler and faster code for dictionary
4041 literals. The oparg for BUILD_MAP now indicates an estimated
4042 dictionary size. There is a new opcode, STORE_MAP, for adding
4043 entries to the dictionary.

4055
Nick Coghlanef01d822007-12-03 12:55:17 +00004056- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00004072- Patch #1739468: Directories and zipfiles containing a __main__.py
4073 file can now be directly executed by passing their name to the
4074 interpreter. The directory/zipfile is automatically inserted as the
4075 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004076
Georg Brandl3ee81df2008-05-17 18:14:43 +00004077- Issue #1265: Fix a problem with sys.settrace, if the tracing
4078 function uses a generator expression when at the same time the
4079 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004080
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004081- sets and frozensets now have an isdisjoint() method.
4082
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004083- optimize the performance of builtin.sum().
4084
Neal Norwitz44f326e2007-10-05 05:29:17 +00004085- Fix warnings found by the new version of the Coverity checker.
4086
Georg Brandl21e99f42010-03-07 15:23:59 +00004087- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004088 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4089 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004090
Georg Brandl3ee81df2008-05-17 18:14:43 +00004091- Issue #1686386: Tuple's tp_repr did not take into account the
4092 possibility of having a self-referential tuple, which is possible
4093 from C code. Nor did object's tp_str consider that a type's tp_str
4094 could do something that could lead to an inifinite recursion.
4095 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4096 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004097
Georg Brandl3ee81df2008-05-17 18:14:43 +00004098- Issue #1164: It was possible to trigger deadlock when using the
4099 'print' statement to write to a file since the GIL was not released
4100 as needed. Now PyObject_Print() does the right thing along with
4101 various tp_print implementations of the built-in types and those in
4102 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004103
Georg Brandl3ee81df2008-05-17 18:14:43 +00004104- Issue #1147: Exceptions were directly allowing string exceptions in
4105 their throw() method even though string exceptions no longer
4106 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004107
Georg Brandl3ee81df2008-05-17 18:14:43 +00004108- Issue #1096: Prevent a segfault from getting the repr of a very
4109 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004110
Brett Cannon1e534b52007-09-07 04:18:30 +00004111- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112 PyObject_Call() never calling back out to Python code to trigger
4113 recursion depth updates/checks. Required the creation of a static
4114 RuntimeError instance in case normalizing an exception put the
4115 recursion check value past its limit. Fixes crashers
4116 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004117
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004131- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004132 __*__ attributes. (Some already existed, e.g., __doc__ and
4133 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004134
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004135- Add -3 option to the interpreter to warn about features that are
4136 deprecated and will be changed/removed in Python 3.0.
4137
Georg Brandl2134e752007-05-21 20:34:16 +00004138- Patch #1686487: you can now pass any mapping after '**' in function
4139 calls.
4140
Collin Winter62903052007-05-18 23:11:24 +00004141- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142 "except E as target:". This is to provide forwards compatibility
4143 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004144
Brett Cannon229cee22007-05-05 01:34:02 +00004145- Deprecate BaseException.message as per PEP 352.
4146
Georg Brandl3ee81df2008-05-17 18:14:43 +00004147- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004148 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004149
Vinay Sajip8549ce32007-05-06 17:53:37 +00004150- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004151 setting a plain string, ie don't expand to single letter identifiers.
4152
Raymond Hettinger13936692007-04-11 18:40:58 +00004153- Request #1191699: Slices can now be pickled.
4154
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004155- Request #1193128: str.translate() now allows a None argument for
4156 translations that only remove characters without re-mapping the
4157 remaining characters.
4158
Georg Brandl5cb76c12007-03-21 09:00:39 +00004159- Patch #1682205: a TypeError while unpacking an iterable is no longer
4160 masked by a generic one with the message "unpack non-sequence".
4161
Neal Norwitzaa754b72007-03-21 06:39:48 +00004162- Remove unused file Python/fmod.c.
4163
Guido van Rossum143b5642007-03-23 04:58:42 +00004164- Bug #1683368: The object.__init__() and object.__new__() methods are
4165 now stricter in rejecting excess arguments. The only time when
4166 either allows excess arguments is when it is not overridden and the
4167 other one is. For backwards compatibility, when both are
4168 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004169 warning later). Also, type.__init__() insists on the same signature
4170 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004171
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4173 object to complex using its __complex__() method before falling back
4174 to the __float__() method. Therefore, the functions in the cmath
4175 module now can operate on objects that define a __complex__()
4176 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004177
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Patch #1623563: allow __class__ assignment for classes with
4179 __slots__. The old and the new class are still required to have the
4180 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004181

4186 ``object.__reduce_ex__()`` is called with an object that is faking
4187 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004188
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189- Patch #1680015: Don't modify __slots__ tuple if it contains an

4193
Georg Brandl7b9c5552007-03-12 14:30:05 +00004194- Bug #1678647: write a newline after printing an exception in any
4195 case, even when converting the value to a string failed.
4196
Georg Brandl871f1bc2007-03-12 13:17:36 +00004197- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198 its argument, if it exists. If not, it will work like before. This
4199 allows customizing the output of dir() in the presence of a
4200 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004201
Collin Winter276887b2007-03-12 16:11:39 +00004202- Patch #922167: Python no longer segfaults when faced with infinitely
4203 self-recursive reload() calls (as reported by bug #742342).
4204
Georg Brandl3ee81df2008-05-17 18:14:43 +00004205- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004208- Patch #1491866: change the complex() constructor to allow
4209 parthensized forms. This means complex(repr(x)) now works instead of
4210 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004211
Georg Brandlaa2321b2007-03-07 00:40:28 +00004212- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004213 makes the filenames the warning module prints much more sensible
4214 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004215
Georg Brandl49aafc92007-03-07 00:34:46 +00004216- Variant of patch #697613: don't exit the interpreter on a SystemExit
4217 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004218 variable is given, but break into the interactive interpreter just
4219 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004227- Patch #1674228: when assigning a slice (old-style), check for the
4228 sq_ass_slice instead of the sq_slice slot.
4229
Georg Brandl3ee81df2008-05-17 18:14:43 +00004230- When printing an unraisable error, don't print exceptions. before
4231 the name. This duplicates the behavior whening normally printing
4232 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004233
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004734- Added a timeout parameter to the constructor of other protocols
4735 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4736 work started with create_connection() and timeout in httplib, and
4737 closes patch #723312.
4738
Vinay Sajip8549ce32007-05-06 17:53:37 +00004739- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00004765 AttributeError instead of an IOError when the server's response
4766 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004767

Georg Brandl3ee81df2008-05-17 18:14:43 +00004772- Patch #1429539: pdb now correctly initializes the __main__ module
4773 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004774 correctly now.
4775

Georg Brandl3ee81df2008-05-17 18:14:43 +00004783- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00004796- Patch #1581073: add a flag to textwrap that prevents the dropping of
4797 whitespace while wrapping.
4798
Georg Brandl92a6bae2007-03-13 17:43:32 +00004799- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004800 are set for invalid interpolation sequences that would lead to
4801 errors on reading back those values.

4844 returned string up to the first NUL character.

4855
Georg Brandl3ee81df2008-05-17 18:14:43 +00004856- unittest now verifies more of its assumptions. In particular,
4857 TestCase and TestSuite subclasses (not instances) are no longer
4858 accepted in TestSuite.addTest(). This should cause no
4859 incompatibility since it never made sense with ordinary subclasses
4860 -- the failure just occurred later, with a more cumbersome
4861 exception.

4871
Georg Brandl3ee81df2008-05-17 18:14:43 +00004872- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00005250 time so that opening a database previously created with the DB_DUP
5251 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5252 opens. Specifically: dictionary assignment to a DB object will
5253 replace all values for a given key when the database allows
5254 duplicate values. DB users should use DB.put(k, v) when they want
5255 to store duplicates; not DB[k] = v.

5262 characters with ASCII value less than 32. Also, it correctly quotes
5263 dots only if they occur on a single line, as opposed to the previous
5264 behavior of quoting dots if they are the second character of any
5265 line.
