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

10*Release date: XXXX-XX-XX*
11
12Core and Builtins
13-----------------
14
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000015- Issue #8329: Don't return the same lists from select.select when no fds are
16 changed.
17
Mark Dickinson82791672010-04-06 16:47:55 +000018- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
19 on 64-bit machines. The shift count for either left or right shift is
20 permitted to be up to sys.maxsize.
21
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000022- Ensure that tokenization of identifiers is not affected by locale.
23
Tarek Ziadé00002952010-04-03 08:37:59 +000024- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
25
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000026- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
27
Eric Smithd44b2fc2010-04-02 12:30:56 +000028- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
29 is called with a non-empty format string. This is an effort to
30 future-proof user code. If a derived class does not currently
31 implement __format__ but later adds its own __format__, it would
32 most likely break user code that had supplied a format string. This
33 will be changed to a DeprecationWaring in Python 3.3 and it will be
34 an error in Python 3.4.
35
Antoine Pitroua57df2c2010-03-31 21:32:15 +000036- Issue #8268: Old-style classes (not just instances) now support weak
37 references.
38
Victor Stinner6cbf90f2010-03-25 00:21:53 +000039- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
40 optimizations are disabled when --with-pydebug is used.
41
Victor Stinnerc7790ed2010-03-22 12:36:28 +000042- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000043
Benjamin Peterson96545892010-03-21 20:21:00 +000044- Issue #6474: Make error message from passing an inadequate number of keyword
45 arguments to a function correct.
46
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000047- Issue #8164: Don't allow lambda functions to have a docstring.
48
Victor Stinner66644262010-03-10 22:30:19 +000049- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000050 (SIGINT). If an error occurs while importing the site module, the error is
51 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000052 module.
53
Collin Winter001a3952010-03-18 21:54:01 +000054- Code objects now support weak references.

57-------
58
Antoine Pitrouf9de5342010-04-05 21:35:07 +000059- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
60 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
61 and `ssl.OPENSSL_VERSION_NUMBER`.
62
Benjamin Peterson76a23c12010-04-04 23:23:22 +000063- Issue #8310: Allow dis to examine new style classes.
64
Mark Dickinson8a950712010-04-03 15:47:46 +000065- Issue #8257: The Decimal construct now accepts a float instance
66 directly, converting that float to a Decimal of equal value:
67
68 >>> Decimal(1.1)
69 Decimal('1.100000000000000088817841970012523233890533447265625')
70
Raymond Hettinger34c35b22010-04-03 10:22:00 +000071- collections.Counter() now supports a subtract() method.
72
Raymond Hettingera551f312010-04-04 18:34:45 +000073- the functools module now has a total_ordering() class decorator
74 to simplify the specifying rich comparisons.
75
Raymond Hettingerbb006cf2010-04-04 21:45:01 +000076- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +000077 old-style comparison functions to new-style key-functions.
78
Mark Dickinson7c63eee2010-04-02 22:27:36 +000079- Issue #8294: The Fraction constructor now accepts Decimal and float
80 instances directly.
81
Mark Dickinsone096e822010-04-02 10:17:07 +000082- Issue #7279: Comparisons involving a Decimal signaling NaN now
83 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000084 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
85 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000086
Mark Dickinson99d80962010-04-02 08:53:22 +000087- Issue #2531: Comparison operations between floats and Decimal
88 instances now return a result based on the numeric values of the
89 operands; previously they returned an arbitrary result based on
90 the relative ordering of id(float) and id(Decimal).
91
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000092- Issue #8233: When run as a script, py_compile.py optionally takes a single
93 argument `-` which tells it to read files to compile from stdin. Each line
94 is read on demand and the named file is compiled immediately. (Original
95 patch by Piotr Ożarowski).
96
97- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
98 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000099
Florent Xicluna58b65662010-03-30 16:29:03 +0000100- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
101 form feed (0x0C) are now considered linebreaks, as specified in Unicode
102 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000103 http://www.unicode.org/reports/tr14/
104
Mark Dickinson9588d992010-03-27 11:14:37 +0000105- Comparisons using one of <, <=, >, >= between a complex instance and
106 a Fractions instance now raise TypeError instead of returning
107 True/False. This makes Fraction <=> complex comparisons consistent with
108 int <=> complex, float <=> complex, and complex <=> complex comparisons.
109
Michael Foorde6410c52010-03-29 20:04:23 +0000110- Addition of ``WeakSet`` to the ``weakref`` module.
111
Vinay Sajipb0623d62010-03-24 14:31:21 +0000112- logging: Added LOG_FTP to SysLogHandler and updated documentation.
113
Florent Xicluna176cda12010-03-22 22:52:11 +0000114- Issue #8205: Remove the "Modules" directory from sys.path when Python is
115 running from the build directory (POSIX only).
116
Florent Xiclunae1f4c922010-03-22 22:45:50 +0000117- Issue #7667: Fix doctest failures with non-ASCII paths.
118
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000119- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
120 didn't support chflags() (for example ZFS under FreeBSD). The error is
121 now silenced.
122
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000123- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
124 deprecated.
125
R. David Murrayc9d1a782010-03-22 15:55:09 +0000126- Issue #7860: platform.uname now reports the correct 'machine' type
127 when Python is running in WOW64 mode on 64 bit Windows.
128
Vinay Sajip804899b2010-03-22 15:29:01 +0000129- logging: Added getChild utility method to Logger and added isEnabledFor
130 method to LoggerAdapter.
131
Vinay Sajip31e928e2010-03-22 13:02:28 +0000132- Issue #8201: logging: Handle situation of non-ASCII and Unicode
133 logger names existing at the same time, causing a Unicode error
134 when configuration code attempted to sort the existing loggers.
135
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000136- Issue #8200: logging: Handle errors when multiprocessing is not
137 fully loaded when logging occurs.
138
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000139- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
140 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
141 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000142
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000143- Issue #8179: Fix macpath.realpath() on a non-existing path.
144
Florent Xicluna2e0a53f2010-03-18 21:50:06 +0000145- Issue #8024: Update the Unicode database to 5.2.
146
Antoine Pitroud7b731d2010-03-17 22:45:39 +0000147- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support
148 writing into objects supporting the new buffer API, for example bytearrays
149 or memoryviews.
150
Matthias Klose8b411682010-03-16 10:48:52 +0000151- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox

155
Matthias Klose358e7ff2010-03-15 13:42:23 +0000156- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
157 the locale.
158
Georg Brandlba83f822010-03-14 09:50:54 +0000159- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000160 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000161 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000162
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000163- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000164 for ``TimedRotatingFileHandler`` by using the modification time of an
165 existing log file to compute the next rollover time. If the log file does
166 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000167
Georg Brandlba83f822010-03-14 09:50:54 +0000168- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Florent Xicluna47627d52010-03-08 15:20:28 +0000174 classes.
175
Georg Brandlba83f822010-03-14 09:50:54 +0000176- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
177 a base64 transfer-encoded payload *after* decoding it; it no longer does.
178 This is a behavior change, so email's minor version number is now bumped, to
179 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000180
Larry Hastings3b958e32010-04-02 11:18:17 +0000181- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is

194
Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000195- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
196
Jesus Cea6557aac2010-03-22 14:22:26 +0000197- Issue #8156: bsddb module updated to version 4.8.4.
198 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
199 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000200
Matthias Klose817acef2010-03-15 00:02:36 +0000201- Issue #8142: Update libffi to the 3.0.9 release.
202
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000203- Issue #8300: When passing a non-integer argument to struct.pack with any
204 integer format code, struct.pack first attempts to convert the non-integer
205 using its __index__ method. If that method is non-existent or raises
206 TypeError it goes on to try the __int__ method, as described below.
207
Georg Brandlba83f822010-03-14 09:50:54 +0000208- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
209 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
210 argument's __int__ method to convert to an integer before packing. It also
211 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
212 was inconsistent: __int__ was used for some integer codes but not for others,
213 and the set of integer codes for which it was used differed between native
214 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000215
Brian Curtin19479fa2010-04-02 21:51:37 +0000216- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a

221
Georg Brandlba83f822010-03-14 09:50:54 +0000222- Issue #7993: Add a test of IO packet processing bandwidth to ccbench. It
223 measures the number of UDP packets processed per second depending on the
224 number of background CPU-bound Python threads.
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000225

247 is now removed (the macro was introduced in 1997!).
248
Larry Hastings402b73f2010-03-25 00:54:54 +0000249- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000250 from Python 3.1. All existing Python CObjects in the main distribution
251 have been converted to capsules. To address backwards-compatibility
252 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

507 class used to represent files stored inside an archive. The new
508 implementation is significantly faster and can be wrapped in a

598Core and Builtins
599-----------------

Georg Brandlba83f822010-03-14 09:50:54 +0000601- The ``__complex__()`` method is now looked up on the class of instances to
602 make it consistent with other special methods.

605 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
606
Mark Dickinson1b34d252010-01-01 17:27:30 +0000607- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000608 DeprecationWarning when passed a float argument where an integer was expected.
609 These functions and methods now raise TypeError instead. The majority of the
610 effects of this change are in the extension modules, but some core functions
611 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
612 and many unicode/str methods.

624
Georg Brandlba83f822010-03-14 09:50:54 +0000625- Issue #1811: Improve accuracy and cross-platform consistency for true division
626 of integers: the result of a/b is now correctly rounded for ints a and b (at
627 least on IEEE 754 platforms), and in particular does not depend on the
628 internal representation of a long.

636
Georg Brandlba83f822010-03-14 09:50:54 +0000637 These executables now work properly with the arch(1) command: ``arch -ppc
638 python`` will start a universal binary version of python in PPC mode (unlike
639 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000774- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
775 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000776
Georg Brandlba83f822010-03-14 09:50:54 +0000777- Issue #3382: 'F' formatting for float and complex now convert the result to
778 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
779 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000780
Georg Brandlba83f822010-03-14 09:50:54 +0000781- Remove switch from "%f" formatting to "%g" formatting for floats larger than
782 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000783
Georg Brandlba83f822010-03-14 09:50:54 +0000784- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
785 1e-100 used to raise OverflowError, but now gives the requested 120
786 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000787
Georg Brandlba83f822010-03-14 09:50:54 +0000788- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000789
Georg Brandlba83f822010-03-14 09:50:54 +0000790- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000791
Georg Brandlba83f822010-03-14 09:50:54 +0000792- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
793 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000794
Georg Brandlba83f822010-03-14 09:50:54 +0000795- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
796 decimal string that's guaranteed to round back to x under correct rounding
797 (with round-half-to-even rounding mode). Previously it gave a string based on
798 rounding x to 17 decimal digits. repr(x) for a complex number behaves
799 similarly. On platforms where the correctly-rounded strtod and dtoa code is
800 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000801
Georg Brandlba83f822010-03-14 09:50:54 +0000802- Issue #7117: On almost all platforms: float-to-string and string-to-float
803 conversions within Python are now correctly rounded. Places these conversions
804 occur include: str for floats and complex numbers; the float and complex
805 constructors; old-style and new-style numeric formatting; serialization and
806 deserialization of floats and complex numbers using marshal, pickle and json;
807 parsing of float and imaginary literals in Python code; Decimal-to-float
808 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000809
Georg Brandlba83f822010-03-14 09:50:54 +0000810 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
811 providing correctly-rounded strtod and dtoa C functions. This code is
812 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
813 the C compiler. There may be a small number of platforms on which correct
814 operation of this code cannot be guaranteed, so the code is not used: notably,
815 this applies to platforms where the C double format is not IEEE 754 binary64,
816 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
817 and Python's configure script is unable to determine how to change the FPU
818 precision. On these platforms conversions use the platform strtod and dtoa,
819 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000820
Georg Brandlba83f822010-03-14 09:50:54 +0000821- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
822 uses the correctly-rounded string <-> float conversions described above (when
823 available), and so produces correctly rounded results that will display nicely
824 under the float repr. There are two related small changes: (1) round now
825 accepts any class with an ``__index__()`` method for its second argument (but
826 no longer accepts floats for the second argument), and (2) an excessively
827 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
828 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000829
Philip Jenveyfab8be22009-11-17 02:42:26 +0000830- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
831
Georg Brandlba83f822010-03-14 09:50:54 +0000832- Fix several issues with ``compile()``. The input can now contain Windows and
833 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +0000834
Georg Brandlba83f822010-03-14 09:50:54 +0000835- Remove length limitation when constructing a complex number from a unicode
836 string.
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000837
Georg Brandlba83f822010-03-14 09:50:54 +0000838- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
839 during the formation of an output tuple.
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000840
Mark Dickinson8d87dc02009-10-25 20:39:06 +0000841- Issue #1087418: Boost performance of bitwise operations for longs.
842
Georg Brandlba83f822010-03-14 09:50:54 +0000843- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
844 which fixes the problem of some exceptions being thrown at shutdown when the
845 interpreter is killed. Patch by Adam Olsen.
Antoine Pitrouefb60c02009-10-20 21:29:37 +0000846
Georg Brandlba83f822010-03-14 09:50:54 +0000847- Issue #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``,
848 and note that they are unsafe and deprecated.
Eric Smithc12781a2009-10-19 14:38:14 +0000849
Georg Brandlba83f822010-03-14 09:50:54 +0000850- Issue #7120: logging: Remove import of multiprocessing which is causing crash
851 in GAE.

Georg Brandlba83f822010-03-14 09:50:54 +0000853- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
854 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +0000855
Georg Brandlba83f822010-03-14 09:50:54 +0000856- Issue #1754094: Improve the stack depth calculation in the compiler. There
857 should be no other effect than a small decrease in memory use. Patch by
858 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000859
Georg Brandlba83f822010-03-14 09:50:54 +0000860- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
861 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000862
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000863- Issue #1571184: The Unicode database contains properties for more characters.
864 The tables for code points representing numeric values, white spaces or line
865 breaks are now generated from the official Unicode Character Database files,
866 and include information from the Unihan.txt file.
867
Benjamin Peterson7adbb5a2009-10-03 20:23:24 +0000868- Issue #7050: Fix a SystemError when trying to use unpacking and augmented

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000970
Georg Brandlba83f822010-03-14 09:50:54 +0000971 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
972 (2) parsing of strings representing infinities and nans was locale aware; and
973 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +0000974
Georg Brandlba83f822010-03-14 09:50:54 +0000975- Issue #5920: For ``float.__format__()``, change the behavior with the empty
976 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
977 but with at least one decimal point and with a default precision
978 of 12. Previously, the behavior the same but with a default precision of 6.
979 This more closely matches ``str()``, and reduces surprises when adding
980 alignment flags to the empty presentation type. This also affects the new
981 complex.__format__ in the same way.
982
983- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
984 classtype's, even if it was None. property now inserts the __doc__ into the

Vinay Sajip35e3b032008-09-01 14:33:59 +00002633 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002634 was correctly parsed but parsing of subsequent arguments failed.
2635
Vinay Sajip35e3b032008-09-01 14:33:59 +00002636- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002637 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2638 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2639 when given a tuple of classes as second argument, were looking up
2640 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2641 type object.
2642
Neal Norwitz18aa3882008-08-24 05:04:52 +00002643- Fix crashes on memory allocation failure found with failmalloc.

2712 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2713 for catch_warnings() also led to an improvement in the raising of a
2714 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002780What's New in Python 2.6 beta 3?
2781================================
2782
Barry Warsaw07a4a382008-08-21 01:15:08 +00002783*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002784
2785Core and Builtins
2786-----------------
2787
Guido van Rossumf8402962008-08-20 15:01:50 +00002788- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2789 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2790 extensions do not automatically benefit from the class attribute
2791 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2792 to their tp_flags field if they care. This is a backwards
2793 compatibility feature; in 3.0, all types will use the cache by
2794 default.
2795
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002796- Keyword arguments can now follow starred arguments. (``f(a, *args,
2797 keyword=23)`` is now valid syntax.)
2798
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002799- ctypes function pointers that are COM methods have a boolean True
2800 value again.
2801
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002802- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2803 by denying s# to parse objects that have a releasebuffer procedure,
2804 and introducing s*.
2805
Georg Brandl1e13ea92008-08-11 09:07:59 +00002806- Issue #3537: Fix an assertion failure when an empty but presized dict
2807 object was stored in the freelist.
2808
Mark Dickinsonb6467572008-08-04 21:30:09 +00002809- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2810 ValueError consistently across platforms.
2811
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002812- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2813 (64bit Unix, for example), unichr() would truncate its argument and return
2814 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2815
Neal Norwitze7d8be82008-07-31 17:17:14 +00002816- Apply security patches from Apple.
2817
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002818- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2819 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2820
Antoine Pitrou92f82162008-07-25 22:22:08 +00002821- Issue #1819: function calls with several named parameters are now on
2822 average 35% faster (as measured by pybench).
2823
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002824- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2825 the python debugger steps into a class statement: the free variables (local
2826 variables defined in an outer scope) would be deleted from the outer scope.
2827
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002828- Issue #2620: Overflow checking when allocating or reallocating memory
2829 was not always being done properly in some python types and extension
2830 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2831 all been updated to perform better checks and places in the code that
2832 would previously leak memory on the error path when such an allocation
2833 failed have been fixed.

2837
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002838- Issue #3612: Added some missing basic types in ctypes.wintypes.
2839
Benjamin Petersone977ad42008-08-20 01:42:01 +00002840- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2841 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2842
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002843- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2844 version reported by these tools does not necessarily follow the python
2845 version numbering scheme, so the module is less strict when parsing it.
2846
Nick Coghlanf70385a2008-08-18 12:42:46 +00002847- Issue #2235: Added Py3k warnings for types which will become unhashable
2848 under the stricter __hash__ inheritance rules in 3.0. Several types
2849 which did not meet the rules for hash invariants and were already
2850 unhashable in 3.0 have now been explicitly flagged as unhashable in
2851 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2852 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2853
Brett Cannon88f801d2008-08-18 00:46:22 +00002854- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2855 imported into the module but exposed as part of the module's API.
2856
Brett Cannon7b96f072008-08-18 00:41:11 +00002857- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2858
Brett Cannon46225e72008-08-18 00:36:52 +00002859- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002861- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2862
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002863- Issue #3575: Incremental decoder's decode function now takes bytearray
2864 by using 's*' instead of 't#'.
2865
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002866- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002867 fails unicode conversion on 2nd parameter. (windows only)
2868
Facundo Batista94f243a2008-08-17 03:38:39 +00002869- Issue 2464. urllib2 now supports a malformation in the URL received
2870 in a redirect.
2871
Brett Cannonabe423e2008-08-16 21:47:07 +00002872- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002873 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002874
Facundo Batistaeb90b782008-08-16 14:44:07 +00002875- Issue #2776: fixed small issue when handling an URL with double slash
2876 after a 302 response in the case of not going through a proxy.
2877
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002878- Issue #2676: in the email package, content-type parsing was hanging on
2879 pathological input because of quadratic or exponential behaviour of a
2880 regular expression.
2881
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002882- Issue #3476: binary buffered reading through the new "io" library is now
2883 thread-safe.
2884
Brett Cannonbf3157b2008-08-14 05:00:03 +00002885- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2886 since mimetools itself is deprecated. Because modules are cached, all
2887 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2888
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002889- Issue #3134: shutil referenced undefined WindowsError symbol.
2890
Robert Schuppenies14646332008-08-10 11:01:53 +00002891- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2892 menu entries were not deleted.
2893
Brett Cannon83e81842008-08-09 23:30:55 +00002894- Copied the implementation of reduce() to _functools.reduce() to have a
2895 version that did not raise a DeprecationWarning under -3.
2896
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002897- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2898 a MemoryError rather than silently stop the iteration.
2899
Guido van Rossum59ce9012008-08-09 14:55:34 +00002900- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2901 to _sre.compile() will now be rejected. This should not affect anybody
2902 since the re.compile() function never generates invalid re-bytecode.
2903
Skip Montanaroa032bf42008-08-08 22:52:51 +00002904- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2905 upon first access it can be automatically initialized from the csv file if
2906 it wasn't initialized during instantiation.
2907
Brett Cannon3aa2a492008-08-06 22:28:09 +00002908- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2909 the reload() built-in has been removed.
2910
Brett Cannon7e30b672008-08-04 21:52:25 +00002911- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002912 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2980-----------------
2981
Georg Brandl3e483f62008-07-16 22:57:41 +00002982- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2983 its methods now allow for items objects that can be converted to
2984 an integer using operator.index().
2985
Mark Dickinson64b7e502008-07-16 09:40:03 +00002986- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2987 produced a ValueError instead of giving the correct float.
2988
Eric Smitha5fa5a22008-07-16 00:11:49 +00002989- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2990 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2991
Mark Dickinson7103aa42008-07-15 19:08:33 +00002992- Issue #3008: the float type has a new instance method 'float.hex'
2993 and a new class method 'float.fromhex' to convert floating-point
2994 numbers to and from hexadecimal strings, respectively.
2995
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002996- Issue #2235: __hash__ is once again inherited by default. To allow
2997 collections.Hashable to remain meaningful in the presence of the
2998 default hash implementation (object.__hash__), it is now possible
2999 to explicit block inheritance of hash by setting __hash__=None at
3000 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3001 level.
3002
Nick Coghlanb028f502008-07-13 14:52:36 +00003003- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3004 the parent module cannot be found while performing an absolute import.
3005 This means that an incorrectly defined __package__ attribute will
3006 now only prevent relative imports in that module rather than causing
3007 all imports from that module to fail.
3008
Nick Coghlan14ff9942008-07-08 14:21:42 +00003009- Issue #2517: Allow unicode messages in Exceptions again by correctly

3019 another thread's dictionary.
3020
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003021- Issue #3004: Minor change to slice.indices(): the start and stop
3022 arguments are now treated identically, making the behaviour easier
3023 to describe and understand. For example, slice(None, -10,
3024 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3025 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3026 10, -1).
3027
Georg Brandl278fc502008-07-19 12:46:12 +00003028- Issue #3219: Calling a function with repeated keyword arguments,
3029 f(a=2, a=23), would not cause a syntax error. This was a regression
3030 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003068- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3069 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003070 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003071 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003087- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3497
Georg Brandl74a1dea2008-05-28 11:21:39 +00003498- Add ``PyType_Modified()`` as a public API to clear the type cache.
3499
3500- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003501
3502- The PyString functions have been renamed to PyBytes. A batch of
3503 defines were added so that the linker still sees the original
3504 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003542- Issue #1631171: Re-implement the 'warnings' module in C (the
3543 original Python code has been kept as backup). This will allow for
3544 using the 'warning's machinery in such places as the parser where
3545 use of pure Python code is not possible. Both the ``showarning()``
3546 and ``formatwarning()`` gain an optional 'line' argument which is
3547 not called by default for backwards-compatibility reasons. Setting
3548 ``warnings.showwarning()`` to an implementation that lacks support
3549 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003574- The getpass module has been improved on Unix. It now uses /dev/tty
3575 by default and uses stderr instead of stdout. A GetPassWarning is
3576 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003591- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003592 extension modules between 32 and 64 bit platforms. See the distutls
3593 build documentation for more information.

3596 threads at once without fear of crashing the Python interpreter. If
3597 file.close() is called while an object is in use by another thread
3598 an IOError exception will be raised and the file will not be closed.
3599
Thomas Hellerf7906482008-04-04 19:43:25 +00003600- The bundled libffi copy is now in sync with the recently released

3605 so the controlled environment will more closely mirror the typical
3606 script environment. This supports setup.py scripts that refer to
3607 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003612- Issue #2550: The approach used by client/server code for obtaining
3613 ports to listen on in network-oriented tests has been refined in an
3614 effort to facilitate running multiple instances of the entire
3615 regression test suite in parallel without issue.
3616 test_support.bind_port() has been fixed such that it will always
3617 return a unique port -- which wasn't always the case with the
3618 previous implementation, especially if socket options had been set
3619 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3620 new implementation of bind_port() will actually raise an exception
3621 if it is passed an AF_INET/SOCK_STREAM socket with either the
3622 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3623 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3624 the socket it's been passed. This currently only applies to
3625 Windows. This option prevents any other sockets from binding to the
3626 host/port we've bound to, thus removing the possibility of the
3627 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3628 when a second SOCK_STREAM socket binds and accepts to a host/port
3629 that's already been bound by another socket. The optional preferred
3630 port parameter to bind_port() has been removed. Under no
3631 circumstances should tests be hard coding ports!
3632
3633 test_support.find_unused_port() has also been introduced, which will
3634 pass a temporary socket object to bind_port() in order to obtain an
3635 unused port. The temporary socket object is then closed and
3636 deleted, and the port is returned. This method should only be used
3637 for obtaining an unused port in order to pass to an external program
3638 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3639 a parameter to a server-oriented class that doesn't give you direct
3640 access to the underlying socket used.
3641
3642 Finally, test_support.HOST has been introduced, which should be used
3643 for the host argument of any relevant socket calls (i.e. bind and
3644 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003645
3646 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003647 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003648 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3649 test_asynchat and test_socket_ssl.
3650
Georg Brandl3ee81df2008-05-17 18:14:43 +00003651 It is now possible for multiple instances of the regression test
3652 suite to run in parallel without issue.

3919-----------------
3920
Fred Drakea8ee94b2008-03-01 02:45:07 +00003921- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003922 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003924- Issue #2067: file.__exit__() now calls subclasses' close() method.
3925
3926- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003927
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003928- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003929 issue 215555 for a discussion.
3930
Eric Smitha73fbe72008-02-23 03:09:44 +00003931- Added the future_builtins module, which contains hex() and oct().
3932 These are the PEP 3127 version of these functions, designed to be
3933 compatible with the hex() and oct() builtins from Python 3.0. They
3934 differ slightly in their output formats from the existing, unchanged
3935 Python 2.6 builtins. The expected usage of the future_builtins
3936 module is:
3937 from future_builtins import hex, oct
3938
Eric Smith7ef40bf2008-02-20 23:34:22 +00003939- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3940 exponents for exponents with absolute value < 100. Follows C99
3941 standard. This is a change on Windows, which would use 3 digits.
3942 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3943 so that any alterations it does to the resulting string will be
3944 available in stringlib/formatter.h (for float.__format__).
3945
Eric Smith5a3c1352008-02-19 13:21:56 +00003946- Implemented PEP 3101, Advanced String Formatting. This adds a new
3947 builtin format(); a format() method for str and unicode; a
3948 __format__() method to object, str, unicode, int, long, float, and
3949 datetime; the class string.Formatter; and the C API
3950 PyObject_Format().
3951
Georg Brandl3ee81df2008-05-17 18:14:43 +00003952- Fixed several potential crashes, all caused by specially crafted
3953 __del__ methods exploiting objects in temporarily inconsistent
3954 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003955
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003956- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003957 prevent a possible crash: an Abstract Base Class would try to access
3958 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003959

Georg Brandl3ee81df2008-05-17 18:14:43 +00003963- Clear all free lists during a gc.collect() of the highest generation
3964 in order to allow pymalloc to free more arenas. Python may give back
3965 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003966
Georg Brandl3ee81df2008-05-17 18:14:43 +00003967- Issue #2045: Fix an infinite recursion triggered when printing a
3968 subclass of collections.defaultdict, if its default_factory is set
3969 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003970
Christian Heimesf75dbef2008-02-08 00:11:31 +00003971- Fixed a minor memory leak in dictobject.c. The content of the free
3972 list was not freed on interpreter shutdown.
3973
Georg Brandl21e99f42010-03-07 15:23:59 +00003974- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003975 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003976
Georg Brandl3ee81df2008-05-17 18:14:43 +00003977- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3978 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003979 to compact the internal free lists of pre-allocted ints and floats.
3980
Georg Brandl3ee81df2008-05-17 18:14:43 +00003981- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3982 calls. Python expected the return type int but the fork familie
3983 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003984

3995 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003996
Georg Brandl3ee81df2008-05-17 18:14:43 +00003997- Patch #1473257: generator objects gain a gi_code attribute. This is
3998 the same object as the func_code attribute of the function that
3999 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004000
Georg Brandl3ee81df2008-05-17 18:14:43 +00004001- Issue #1920: "while 0" statements were completely removed by the
4002 compiler, even in the presence of an "else" clause, which is

4004 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00004006- A few crashers fixed: weakref_in_del.py (issue #1377858);
4007 loosing_dict_ref.py (issue #1303614, test67.py);
4008 borrowed_ref_[34].py (not in tracker).
4009
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004010- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004011 suppressed while an extension is loaded by calling SetErrorMode in
4012 dynload_win.c. The error is still reported properly.
4013
Georg Brandl3ee81df2008-05-17 18:14:43 +00004014- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004015 several extension methods and modules do not work without unicode
4016 support.
4017
Georg Brandl26543b12008-01-21 18:36:51 +00004018- Issue #1882: when compiling code from a string, encoding cookies in the
4019 second line of code were not always recognized correctly.
4020
Georg Brandl14404b62008-01-19 19:27:05 +00004021- Issue #1679: "0x" was taken as a valid integer literal.
4022
Georg Brandl6caad7d2008-01-26 14:19:22 +00004023- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004024 added.
4025
Christian Heimesc94e2b52008-01-14 04:13:37 +00004026- sys.float_info / PyFloat_GetInfo: The floating point information
4027 object was converted from a dict to a specialized structseq object.
4028
Georg Brandl3ee81df2008-05-17 18:14:43 +00004029- Patch #1816: Added sys.flags structseq. It exposes the status of
4030 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004031
Georg Brandl3ee81df2008-05-17 18:14:43 +00004032- Objects/structseq.c: Implemented new structseq representation. The
4033 patch makes structseqs (e.g. the return value of os.stat) more
4034 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004035
Georg Brandl3ee81df2008-05-17 18:14:43 +00004036- Patch #1700288: added a type attribute cache that caches method
4037 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004038
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004039- Bug #1776: __import__() no longer accepts filenames on any platform.
4040 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004041
Georg Brandlaed6c662008-01-07 17:25:53 +00004042- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4043
Georg Brandl3ee81df2008-05-17 18:14:43 +00004044- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4045 envvar and sys.dont_write_bytecode attribute. All these can be set
4046 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004047
Georg Brandl3ee81df2008-05-17 18:14:43 +00004048- Improve some exception messages when Windows fails to load an
4049 extension module. Now we get for example '%1 is not a valid Win32
4050 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004051
Georg Brandl3ee81df2008-05-17 18:14:43 +00004052- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004054- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4055 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004056
Christian Heimes0a8143f2007-12-18 23:22:54 +00004057- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004058 and INF. float("nan"), float("inf") and float("-inf") now work on
4059 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004060
Georg Brandl3ee81df2008-05-17 18:14:43 +00004061- Compiler now generates simpler and faster code for dictionary
4062 literals. The oparg for BUILD_MAP now indicates an estimated
4063 dictionary size. There is a new opcode, STORE_MAP, for adding
4064 entries to the dictionary.

4079 __package__ attribute.
4080
Georg Brandl3ee81df2008-05-17 18:14:43 +00004081- Issue #1402: Fix a crash on exit, when another thread is still
4082 running, and if the deallocation of its frames somehow calls the
4083 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004084

Georg Brandl3ee81df2008-05-17 18:14:43 +00004093- Patch #1739468: Directories and zipfiles containing a __main__.py
4094 file can now be directly executed by passing their name to the
4095 interpreter. The directory/zipfile is automatically inserted as the
4096 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004097
Georg Brandl3ee81df2008-05-17 18:14:43 +00004098- Issue #1265: Fix a problem with sys.settrace, if the tracing
4099 function uses a generator expression when at the same time the
4100 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004101
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004102- sets and frozensets now have an isdisjoint() method.
4103
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004104- optimize the performance of builtin.sum().
4105
Neal Norwitz44f326e2007-10-05 05:29:17 +00004106- Fix warnings found by the new version of the Coverity checker.
4107
Georg Brandl21e99f42010-03-07 15:23:59 +00004108- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004109 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4110 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004111
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112- Issue #1686386: Tuple's tp_repr did not take into account the
4113 possibility of having a self-referential tuple, which is possible
4114 from C code. Nor did object's tp_str consider that a type's tp_str
4115 could do something that could lead to an inifinite recursion.
4116 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4117 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004118
Georg Brandl3ee81df2008-05-17 18:14:43 +00004119- Issue #1164: It was possible to trigger deadlock when using the
4120 'print' statement to write to a file since the GIL was not released
4121 as needed. Now PyObject_Print() does the right thing along with
4122 various tp_print implementations of the built-in types and those in
4123 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004124
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Issue #1147: Exceptions were directly allowing string exceptions in
4126 their throw() method even though string exceptions no longer
4127 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004128
Georg Brandl3ee81df2008-05-17 18:14:43 +00004129- Issue #1096: Prevent a segfault from getting the repr of a very
4130 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004131
Brett Cannon1e534b52007-09-07 04:18:30 +00004132- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004133 PyObject_Call() never calling back out to Python code to trigger
4134 recursion depth updates/checks. Required the creation of a static
4135 RuntimeError instance in case normalizing an exception put the
4136 recursion check value past its limit. Fixes crashers
4137 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004138
Georg Brandl3ee81df2008-05-17 18:14:43 +00004139- Patch #1031213: Decode source line in SyntaxErrors back to its

4143 with %G.
4144
Georg Brandl3ee81df2008-05-17 18:14:43 +00004145- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00004152- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004153 __*__ attributes. (Some already existed, e.g., __doc__ and
4154 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004155
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004156- Add -3 option to the interpreter to warn about features that are
4157 deprecated and will be changed/removed in Python 3.0.
4158
Georg Brandl2134e752007-05-21 20:34:16 +00004159- Patch #1686487: you can now pass any mapping after '**' in function
4160 calls.
4161
Collin Winter62903052007-05-18 23:11:24 +00004162- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163 "except E as target:". This is to provide forwards compatibility
4164 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004165
Brett Cannon229cee22007-05-05 01:34:02 +00004166- Deprecate BaseException.message as per PEP 352.
4167
Georg Brandl3ee81df2008-05-17 18:14:43 +00004168- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004169 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004170
Vinay Sajip8549ce32007-05-06 17:53:37 +00004171- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004172 setting a plain string, ie don't expand to single letter identifiers.
4173
Raymond Hettinger13936692007-04-11 18:40:58 +00004174- Request #1191699: Slices can now be pickled.
4175
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004176- Request #1193128: str.translate() now allows a None argument for
4177 translations that only remove characters without re-mapping the
4178 remaining characters.
4179
Georg Brandl5cb76c12007-03-21 09:00:39 +00004180- Patch #1682205: a TypeError while unpacking an iterable is no longer
4181 masked by a generic one with the message "unpack non-sequence".
4182
Neal Norwitzaa754b72007-03-21 06:39:48 +00004183- Remove unused file Python/fmod.c.
4184
Guido van Rossum143b5642007-03-23 04:58:42 +00004185- Bug #1683368: The object.__init__() and object.__new__() methods are
4186 now stricter in rejecting excess arguments. The only time when
4187 either allows excess arguments is when it is not overridden and the
4188 other one is. For backwards compatibility, when both are
4189 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004190 warning later). Also, type.__init__() insists on the same signature
4191 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4194 object to complex using its __complex__() method before falling back
4195 to the __float__() method. Therefore, the functions in the cmath
4196 module now can operate on objects that define a __complex__()
4197 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004198
Georg Brandl3ee81df2008-05-17 18:14:43 +00004199- Patch #1623563: allow __class__ assignment for classes with
4200 __slots__. The old and the new class are still required to have the
4201 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004202
Georg Brandl3ee81df2008-05-17 18:14:43 +00004203- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004206- Patch #1462488: Python no longer segfaults when
4207 ``object.__reduce_ex__()`` is called with an object that is faking
4208 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004209
Georg Brandl3ee81df2008-05-17 18:14:43 +00004210- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00004213- Patch #1444529: the builtin compile() now accepts keyword arguments.
4214
Georg Brandl7b9c5552007-03-12 14:30:05 +00004215- Bug #1678647: write a newline after printing an exception in any
4216 case, even when converting the value to a string failed.
4217
Georg Brandl871f1bc2007-03-12 13:17:36 +00004218- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004219 its argument, if it exists. If not, it will work like before. This
4220 allows customizing the output of dir() in the presence of a
4221 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004222
Collin Winter276887b2007-03-12 16:11:39 +00004223- Patch #922167: Python no longer segfaults when faced with infinitely
4224 self-recursive reload() calls (as reported by bug #742342).
4225
Georg Brandl3ee81df2008-05-17 18:14:43 +00004226- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004229- Patch #1491866: change the complex() constructor to allow
4230 parthensized forms. This means complex(repr(x)) now works instead of
4231 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004232
Georg Brandlaa2321b2007-03-07 00:40:28 +00004233- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234 makes the filenames the warning module prints much more sensible
4235 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004236
Georg Brandl49aafc92007-03-07 00:34:46 +00004237- Variant of patch #697613: don't exit the interpreter on a SystemExit
4238 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004239 variable is given, but break into the interactive interpreter just
4240 like on other exceptions or normal program exit.

4742 ".cpp" too.
4743
Facundo Batistad918a652007-04-24 13:54:38 +00004744- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004745 the client's request was successfully received, understood, and
4746 accepted. Now in these cases no error is raised in urllib (issue
4747 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004755- Added a timeout parameter to the constructor of other protocols
4756 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4757 work started with create_connection() and timeout in httplib, and
4758 closes patch #723312.
4759
Vinay Sajip8549ce32007-05-06 17:53:37 +00004760- Patch #1676823: Added create_connection() to socket.py, which may be
4761 called with a timeout, and use it from httplib (whose HTTPConnection

Facundo Batista07c78be2007-03-23 18:54:07 +00004763
Martin v. Löwis0af33882007-03-23 13:27:15 +00004764- Bug #978833: Revert r50844, as it broke _socketobject.dup.

4784
Georg Brandlf66b6032007-03-14 08:27:52 +00004785- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004786 AttributeError instead of an IOError when the server's response
4787 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004788
Georg Brandl3ee81df2008-05-17 18:14:43 +00004789- Patch #957650: "%var%" environment variable references are now
4790 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00004793- Patch #1429539: pdb now correctly initializes the __main__ module
4794 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004795 correctly now.
4796

4803
Georg Brandl3ee81df2008-05-17 18:14:43 +00004804- Patch #1530482: add pydoc.render_doc() which returns the
4805 documentation for a thing instead of paging it to stdout, which
4806 pydoc.doc() does.

4814 parameter which can be set to False to prevent the default
4815 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00004817- Patch #1581073: add a flag to textwrap that prevents the dropping of
4818 whitespace while wrapping.
4819
Georg Brandl92a6bae2007-03-13 17:43:32 +00004820- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004821 are set for invalid interpolation sequences that would lead to
4822 errors on reading back those values.

4839 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004857

4865 returned string up to the first NUL character.

4876
Georg Brandl3ee81df2008-05-17 18:14:43 +00004877- unittest now verifies more of its assumptions. In particular,
4878 TestCase and TestSuite subclasses (not instances) are no longer
4879 accepted in TestSuite.addTest(). This should cause no
4880 incompatibility since it never made sense with ordinary subclasses
4881 -- the failure just occurred later, with a more cumbersome
4882 exception.

4891 given a unicode argument and os.listdir() returns unicode filenames.
4892
Georg Brandl3ee81df2008-05-17 18:14:43 +00004893- Patch #1673619: setup.py identifies extension modules it doesn't

4895 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005271 time so that opening a database previously created with the DB_DUP
5272 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5273 opens. Specifically: dictionary assignment to a DB object will
5274 replace all values for a given key when the database allows
5275 duplicate values. DB users should use DB.put(k, v) when they want
5276 to store duplicates; not DB[k] = v.

5283 characters with ASCII value less than 32. Also, it correctly quotes
5284 dots only if they occur on a single line, as opposed to the previous
5285 behavior of quoting dots if they are the second character of any
5286 line.
