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
Mark Dickinson82791672010-04-06 16:47:55 +000015- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
16 on 64-bit machines. The shift count for either left or right shift is
17 permitted to be up to sys.maxsize.
18
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000019- Ensure that tokenization of identifiers is not affected by locale.
20
Tarek Ziadé00002952010-04-03 08:37:59 +000021- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
22
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000023- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
24
Eric Smithd44b2fc2010-04-02 12:30:56 +000025- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
26 is called with a non-empty format string. This is an effort to
27 future-proof user code. If a derived class does not currently
28 implement __format__ but later adds its own __format__, it would
29 most likely break user code that had supplied a format string. This
30 will be changed to a DeprecationWaring in Python 3.3 and it will be
31 an error in Python 3.4.
32
Antoine Pitroua57df2c2010-03-31 21:32:15 +000033- Issue #8268: Old-style classes (not just instances) now support weak
34 references.
35
Victor Stinner6cbf90f2010-03-25 00:21:53 +000036- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
37 optimizations are disabled when --with-pydebug is used.
38
Victor Stinnerc7790ed2010-03-22 12:36:28 +000039- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000040
Benjamin Peterson96545892010-03-21 20:21:00 +000041- Issue #6474: Make error message from passing an inadequate number of keyword
42 arguments to a function correct.
43
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000044- Issue #8164: Don't allow lambda functions to have a docstring.
45
Victor Stinner66644262010-03-10 22:30:19 +000046- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000047 (SIGINT). If an error occurs while importing the site module, the error is
48 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000049 module.
50
Collin Winter001a3952010-03-18 21:54:01 +000051- Code objects now support weak references.
52
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +000053Library
54-------
55
Antoine Pitrouf9de5342010-04-05 21:35:07 +000056- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
57 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
58 and `ssl.OPENSSL_VERSION_NUMBER`.
59
Benjamin Peterson76a23c12010-04-04 23:23:22 +000060- Issue #8310: Allow dis to examine new style classes.
61
Mark Dickinson8a950712010-04-03 15:47:46 +000062- Issue #8257: The Decimal construct now accepts a float instance
63 directly, converting that float to a Decimal of equal value:
64
65 >>> Decimal(1.1)
66 Decimal('1.100000000000000088817841970012523233890533447265625')
67
Raymond Hettinger34c35b22010-04-03 10:22:00 +000068- collections.Counter() now supports a subtract() method.
69
Raymond Hettingera551f312010-04-04 18:34:45 +000070- the functools module now has a total_ordering() class decorator
71 to simplify the specifying rich comparisons.
72
Raymond Hettingerbb006cf2010-04-04 21:45:01 +000073- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +000074 old-style comparison functions to new-style key-functions.
75
Mark Dickinson7c63eee2010-04-02 22:27:36 +000076- Issue #8294: The Fraction constructor now accepts Decimal and float
77 instances directly.
78
Mark Dickinsone096e822010-04-02 10:17:07 +000079- Issue #7279: Comparisons involving a Decimal signaling NaN now
80 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000081 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
82 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000083
Mark Dickinson99d80962010-04-02 08:53:22 +000084- Issue #2531: Comparison operations between floats and Decimal
85 instances now return a result based on the numeric values of the
86 operands; previously they returned an arbitrary result based on
87 the relative ordering of id(float) and id(Decimal).
88
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000089- Issue #8233: When run as a script, py_compile.py optionally takes a single
90 argument `-` which tells it to read files to compile from stdin. Each line
91 is read on demand and the named file is compiled immediately. (Original
92 patch by Piotr Ożarowski).
93
94- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
95 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000096
Florent Xicluna58b65662010-03-30 16:29:03 +000097- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
98 form feed (0x0C) are now considered linebreaks, as specified in Unicode
99 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000100 http://www.unicode.org/reports/tr14/
101
Mark Dickinson9588d992010-03-27 11:14:37 +0000102- Comparisons using one of <, <=, >, >= between a complex instance and
103 a Fractions instance now raise TypeError instead of returning
104 True/False. This makes Fraction <=> complex comparisons consistent with
105 int <=> complex, float <=> complex, and complex <=> complex comparisons.
106
Michael Foorde6410c52010-03-29 20:04:23 +0000107- Addition of ``WeakSet`` to the ``weakref`` module.
108
Vinay Sajipb0623d62010-03-24 14:31:21 +0000109- logging: Added LOG_FTP to SysLogHandler and updated documentation.
110
Florent Xicluna176cda12010-03-22 22:52:11 +0000111- Issue #8205: Remove the "Modules" directory from sys.path when Python is
112 running from the build directory (POSIX only).
113
Florent Xiclunae1f4c922010-03-22 22:45:50 +0000114- Issue #7667: Fix doctest failures with non-ASCII paths.
115
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000116- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
117 didn't support chflags() (for example ZFS under FreeBSD). The error is
118 now silenced.
119
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000120- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
121 deprecated.
122
R. David Murrayc9d1a782010-03-22 15:55:09 +0000123- Issue #7860: platform.uname now reports the correct 'machine' type
124 when Python is running in WOW64 mode on 64 bit Windows.
125
Vinay Sajip804899b2010-03-22 15:29:01 +0000126- logging: Added getChild utility method to Logger and added isEnabledFor
127 method to LoggerAdapter.
128
Vinay Sajip31e928e2010-03-22 13:02:28 +0000129- Issue #8201: logging: Handle situation of non-ASCII and Unicode
130 logger names existing at the same time, causing a Unicode error
131 when configuration code attempted to sort the existing loggers.
132
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000133- Issue #8200: logging: Handle errors when multiprocessing is not
134 fully loaded when logging occurs.
135
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000136- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
137 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
138 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000139
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000140- Issue #8179: Fix macpath.realpath() on a non-existing path.
141
Florent Xicluna2e0a53f2010-03-18 21:50:06 +0000142- Issue #8024: Update the Unicode database to 5.2.
143
Antoine Pitroud7b731d2010-03-17 22:45:39 +0000144- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support
145 writing into objects supporting the new buffer API, for example bytearrays
146 or memoryviews.
147
Matthias Klose8b411682010-03-16 10:48:52 +0000148- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox

152
Matthias Klose358e7ff2010-03-15 13:42:23 +0000153- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
154 the locale.
155
Georg Brandlba83f822010-03-14 09:50:54 +0000156- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000157 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000158 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000159
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000160- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000161 for ``TimedRotatingFileHandler`` by using the modification time of an
162 existing log file to compute the next rollover time. If the log file does
163 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000164
Georg Brandlba83f822010-03-14 09:50:54 +0000165- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Florent Xicluna47627d52010-03-08 15:20:28 +0000171 classes.
172
Georg Brandlba83f822010-03-14 09:50:54 +0000173- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
174 a base64 transfer-encoded payload *after* decoding it; it no longer does.
175 This is a behavior change, so email's minor version number is now bumped, to
176 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000177
Larry Hastings3b958e32010-04-02 11:18:17 +0000178- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is

Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000192- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
193
Jesus Cea6557aac2010-03-22 14:22:26 +0000194- Issue #8156: bsddb module updated to version 4.8.4.
195 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
196 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000197
Matthias Klose817acef2010-03-15 00:02:36 +0000198- Issue #8142: Update libffi to the 3.0.9 release.
199
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000200- Issue #8300: When passing a non-integer argument to struct.pack with any
201 integer format code, struct.pack first attempts to convert the non-integer
202 using its __index__ method. If that method is non-existent or raises
203 TypeError it goes on to try the __int__ method, as described below.
204
Georg Brandlba83f822010-03-14 09:50:54 +0000205- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
206 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
207 argument's __int__ method to convert to an integer before packing. It also
208 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
209 was inconsistent: __int__ was used for some integer codes but not for others,
210 and the set of integer codes for which it was used differed between native
211 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000212
Brian Curtin19479fa2010-04-02 21:51:37 +0000213- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a

Georg Brandlba83f822010-03-14 09:50:54 +0000219- Issue #7993: Add a test of IO packet processing bandwidth to ccbench. It
220 measures the number of UDP packets processed per second depending on the
221 number of background CPU-bound Python threads.
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000222

243 function declaration, which was kept for backwards compatibility reasons,
244 is now removed (the macro was introduced in 1997!).
245
Larry Hastings402b73f2010-03-25 00:54:54 +0000246- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000247 from Python 3.1. All existing Python CObjects in the main distribution
248 have been converted to capsules. To address backwards-compatibility
249 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000518- Issue #7748: Since unicode values are supported for some metadata options in
519 Distutils, the DistributionMetadata get_* methods will now return an utf-8
520 encoded string for them. This ensures that the upload and register commands
521 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000590What's New in Python 2.7 alpha 2?
591=================================

Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000593*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000594
595Core and Builtins
596-----------------
597
Georg Brandlba83f822010-03-14 09:50:54 +0000598- The ``__complex__()`` method is now looked up on the class of instances to
599 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000601- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
602 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
603
Mark Dickinson1b34d252010-01-01 17:27:30 +0000604- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000605 DeprecationWarning when passed a float argument where an integer was expected.
606 These functions and methods now raise TypeError instead. The majority of the
607 effects of this change are in the extension modules, but some core functions
608 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
609 and many unicode/str methods.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000619- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
620 used to drop the time part of the result.
621
Georg Brandlba83f822010-03-14 09:50:54 +0000622- Issue #1811: Improve accuracy and cross-platform consistency for true division
623 of integers: the result of a/b is now correctly rounded for ints a and b (at
624 least on IEEE 754 platforms), and in particular does not depend on the
625 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +0000627- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

633
Georg Brandlba83f822010-03-14 09:50:54 +0000634 These executables now work properly with the arch(1) command: ``arch -ppc
635 python`` will start a universal binary version of python in PPC mode (unlike
636 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000637
Georg Brandlba83f822010-03-14 09:50:54 +0000638- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

Georg Brandlba83f822010-03-14 09:50:54 +0000771- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
772 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000773
Georg Brandlba83f822010-03-14 09:50:54 +0000774- Issue #3382: 'F' formatting for float and complex now convert the result to
775 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
776 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000777
Georg Brandlba83f822010-03-14 09:50:54 +0000778- Remove switch from "%f" formatting to "%g" formatting for floats larger than
779 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000780
Georg Brandlba83f822010-03-14 09:50:54 +0000781- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
782 1e-100 used to raise OverflowError, but now gives the requested 120
783 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000784
Georg Brandlba83f822010-03-14 09:50:54 +0000785- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000786
Georg Brandlba83f822010-03-14 09:50:54 +0000787- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000788
Georg Brandlba83f822010-03-14 09:50:54 +0000789- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
790 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000791
Georg Brandlba83f822010-03-14 09:50:54 +0000792- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
793 decimal string that's guaranteed to round back to x under correct rounding
794 (with round-half-to-even rounding mode). Previously it gave a string based on
795 rounding x to 17 decimal digits. repr(x) for a complex number behaves
796 similarly. On platforms where the correctly-rounded strtod and dtoa code is
797 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000798
Georg Brandlba83f822010-03-14 09:50:54 +0000799- Issue #7117: On almost all platforms: float-to-string and string-to-float
800 conversions within Python are now correctly rounded. Places these conversions
801 occur include: str for floats and complex numbers; the float and complex
802 constructors; old-style and new-style numeric formatting; serialization and
803 deserialization of floats and complex numbers using marshal, pickle and json;
804 parsing of float and imaginary literals in Python code; Decimal-to-float
805 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000806
Georg Brandlba83f822010-03-14 09:50:54 +0000807 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
808 providing correctly-rounded strtod and dtoa C functions. This code is
809 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
810 the C compiler. There may be a small number of platforms on which correct
811 operation of this code cannot be guaranteed, so the code is not used: notably,
812 this applies to platforms where the C double format is not IEEE 754 binary64,
813 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
814 and Python's configure script is unable to determine how to change the FPU
815 precision. On these platforms conversions use the platform strtod and dtoa,
816 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000817
Georg Brandlba83f822010-03-14 09:50:54 +0000818- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
819 uses the correctly-rounded string <-> float conversions described above (when
820 available), and so produces correctly rounded results that will display nicely
821 under the float repr. There are two related small changes: (1) round now
822 accepts any class with an ``__index__()`` method for its second argument (but
823 no longer accepts floats for the second argument), and (2) an excessively
824 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
825 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000826
Philip Jenveyfab8be22009-11-17 02:42:26 +0000827- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
828
Georg Brandlba83f822010-03-14 09:50:54 +0000829- Fix several issues with ``compile()``. The input can now contain Windows and
830 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +0000831
Georg Brandlba83f822010-03-14 09:50:54 +0000832- Remove length limitation when constructing a complex number from a unicode
833 string.

839
Georg Brandlba83f822010-03-14 09:50:54 +0000840- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
841 which fixes the problem of some exceptions being thrown at shutdown when the
842 interpreter is killed. Patch by Adam Olsen.

Georg Brandlba83f822010-03-14 09:50:54 +0000850- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
851 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +0000852
Georg Brandlba83f822010-03-14 09:50:54 +0000853- Issue #1754094: Improve the stack depth calculation in the compiler. There
854 should be no other effect than a small decrease in memory use. Patch by
855 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000856

858 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000859
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000860- Issue #1571184: The Unicode database contains properties for more characters.
861 The tables for code points representing numeric values, white spaces or line
862 breaks are now generated from the official Unicode Character Database files,
863 and include information from the Unihan.txt file.
864

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000967
Georg Brandlba83f822010-03-14 09:50:54 +0000968 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
969 (2) parsing of strings representing infinities and nans was locale aware; and
970 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +0000972- Issue #5920: For ``float.__format__()``, change the behavior with the empty
973 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
974 but with at least one decimal point and with a default precision
975 of 12. Previously, the behavior the same but with a default precision of 6.
976 This more closely matches ``str()``, and reduces surprises when adding
977 alignment flags to the empty presentation type. This also affects the new
978 complex.__format__ in the same way.
979
980- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
981 classtype's, even if it was None. property now inserts the __doc__ into the

Vinay Sajip35e3b032008-09-01 14:33:59 +00002630 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002631 was correctly parsed but parsing of subsequent arguments failed.
2632
Vinay Sajip35e3b032008-09-01 14:33:59 +00002633- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002634 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2635 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2636 when given a tuple of classes as second argument, were looking up
2637 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2638 type object.
2639
Neal Norwitz18aa3882008-08-24 05:04:52 +00002640- Fix crashes on memory allocation failure found with failmalloc.

2709 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2710 for catch_warnings() also led to an improvement in the raising of a
2711 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002777What's New in Python 2.6 beta 3?
2778================================
2779
Barry Warsaw07a4a382008-08-21 01:15:08 +00002780*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002781
2782Core and Builtins
2783-----------------
2784
Guido van Rossumf8402962008-08-20 15:01:50 +00002785- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2786 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2787 extensions do not automatically benefit from the class attribute
2788 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2789 to their tp_flags field if they care. This is a backwards
2790 compatibility feature; in 3.0, all types will use the cache by
2791 default.
2792
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002793- Keyword arguments can now follow starred arguments. (``f(a, *args,
2794 keyword=23)`` is now valid syntax.)
2795
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002796- ctypes function pointers that are COM methods have a boolean True
2797 value again.
2798
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002799- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2800 by denying s# to parse objects that have a releasebuffer procedure,
2801 and introducing s*.
2802
Georg Brandl1e13ea92008-08-11 09:07:59 +00002803- Issue #3537: Fix an assertion failure when an empty but presized dict
2804 object was stored in the freelist.
2805
Mark Dickinsonb6467572008-08-04 21:30:09 +00002806- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2807 ValueError consistently across platforms.
2808
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002809- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2810 (64bit Unix, for example), unichr() would truncate its argument and return
2811 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2812
Neal Norwitze7d8be82008-07-31 17:17:14 +00002813- Apply security patches from Apple.
2814
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002815- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2816 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2817
Antoine Pitrou92f82162008-07-25 22:22:08 +00002818- Issue #1819: function calls with several named parameters are now on
2819 average 35% faster (as measured by pybench).
2820
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002821- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2822 the python debugger steps into a class statement: the free variables (local
2823 variables defined in an outer scope) would be deleted from the outer scope.
2824
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002825- Issue #2620: Overflow checking when allocating or reallocating memory
2826 was not always being done properly in some python types and extension
2827 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2828 all been updated to perform better checks and places in the code that
2829 would previously leak memory on the error path when such an allocation
2830 failed have been fixed.

2834
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002835- Issue #3612: Added some missing basic types in ctypes.wintypes.
2836
Benjamin Petersone977ad42008-08-20 01:42:01 +00002837- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2838 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2839
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002840- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2841 version reported by these tools does not necessarily follow the python
2842 version numbering scheme, so the module is less strict when parsing it.
2843
Nick Coghlanf70385a2008-08-18 12:42:46 +00002844- Issue #2235: Added Py3k warnings for types which will become unhashable
2845 under the stricter __hash__ inheritance rules in 3.0. Several types
2846 which did not meet the rules for hash invariants and were already
2847 unhashable in 3.0 have now been explicitly flagged as unhashable in
2848 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2849 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2850
Brett Cannon88f801d2008-08-18 00:46:22 +00002851- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2852 imported into the module but exposed as part of the module's API.
2853
Brett Cannon7b96f072008-08-18 00:41:11 +00002854- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2855
Brett Cannon46225e72008-08-18 00:36:52 +00002856- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002858- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2859
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002860- Issue #3575: Incremental decoder's decode function now takes bytearray
2861 by using 's*' instead of 't#'.
2862
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002863- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002864 fails unicode conversion on 2nd parameter. (windows only)
2865
Facundo Batista94f243a2008-08-17 03:38:39 +00002866- Issue 2464. urllib2 now supports a malformation in the URL received
2867 in a redirect.
2868
Brett Cannonabe423e2008-08-16 21:47:07 +00002869- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002870 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002871
Facundo Batistaeb90b782008-08-16 14:44:07 +00002872- Issue #2776: fixed small issue when handling an URL with double slash
2873 after a 302 response in the case of not going through a proxy.
2874
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002875- Issue #2676: in the email package, content-type parsing was hanging on
2876 pathological input because of quadratic or exponential behaviour of a
2877 regular expression.
2878
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002879- Issue #3476: binary buffered reading through the new "io" library is now
2880 thread-safe.
2881
Brett Cannonbf3157b2008-08-14 05:00:03 +00002882- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2883 since mimetools itself is deprecated. Because modules are cached, all
2884 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2885
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002886- Issue #3134: shutil referenced undefined WindowsError symbol.
2887
Robert Schuppenies14646332008-08-10 11:01:53 +00002888- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2889 menu entries were not deleted.
2890
Brett Cannon83e81842008-08-09 23:30:55 +00002891- Copied the implementation of reduce() to _functools.reduce() to have a
2892 version that did not raise a DeprecationWarning under -3.
2893
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002894- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2895 a MemoryError rather than silently stop the iteration.
2896
Guido van Rossum59ce9012008-08-09 14:55:34 +00002897- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2898 to _sre.compile() will now be rejected. This should not affect anybody
2899 since the re.compile() function never generates invalid re-bytecode.
2900
Skip Montanaroa032bf42008-08-08 22:52:51 +00002901- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2902 upon first access it can be automatically initialized from the csv file if
2903 it wasn't initialized during instantiation.
2904
Brett Cannon3aa2a492008-08-06 22:28:09 +00002905- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2906 the reload() built-in has been removed.
2907
Brett Cannon7e30b672008-08-04 21:52:25 +00002908- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002909 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002920 asking for a specific length. This problem only affected files opened

2977-----------------
2978
Georg Brandl3e483f62008-07-16 22:57:41 +00002979- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2980 its methods now allow for items objects that can be converted to
2981 an integer using operator.index().
2982
Mark Dickinson64b7e502008-07-16 09:40:03 +00002983- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2984 produced a ValueError instead of giving the correct float.
2985
Eric Smitha5fa5a22008-07-16 00:11:49 +00002986- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2987 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2988
Mark Dickinson7103aa42008-07-15 19:08:33 +00002989- Issue #3008: the float type has a new instance method 'float.hex'
2990 and a new class method 'float.fromhex' to convert floating-point
2991 numbers to and from hexadecimal strings, respectively.
2992
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002993- Issue #2235: __hash__ is once again inherited by default. To allow
2994 collections.Hashable to remain meaningful in the presence of the
2995 default hash implementation (object.__hash__), it is now possible
2996 to explicit block inheritance of hash by setting __hash__=None at
2997 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2998 level.
2999
Nick Coghlanb028f502008-07-13 14:52:36 +00003000- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3001 the parent module cannot be found while performing an absolute import.
3002 This means that an incorrectly defined __package__ attribute will
3003 now only prevent relative imports in that module rather than causing
3004 all imports from that module to fail.
3005
Nick Coghlan14ff9942008-07-08 14:21:42 +00003006- Issue #2517: Allow unicode messages in Exceptions again by correctly

3016 another thread's dictionary.
3017
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003018- Issue #3004: Minor change to slice.indices(): the start and stop
3019 arguments are now treated identically, making the behaviour easier
3020 to describe and understand. For example, slice(None, -10,
3021 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3022 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3023 10, -1).
3024
Georg Brandl278fc502008-07-19 12:46:12 +00003025- Issue #3219: Calling a function with repeated keyword arguments,
3026 f(a=2, a=23), would not cause a syntax error. This was a regression
3027 from 2.4 caused by the switch to the new compiler.

3030 other freelists. Changes their CompactFreeList apis into

3038 error when they failed.
3039
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003040- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003065- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3066 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003067 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003068 content-length. The problem had been corrected in the 2.4 branch, but never
3069 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003084- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl74a1dea2008-05-28 11:21:39 +00003495- Add ``PyType_Modified()`` as a public API to clear the type cache.
3496
3497- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003498
3499- The PyString functions have been renamed to PyBytes. A batch of
3500 defines were added so that the linker still sees the original
3501 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003539- Issue #1631171: Re-implement the 'warnings' module in C (the
3540 original Python code has been kept as backup). This will allow for
3541 using the 'warning's machinery in such places as the parser where
3542 use of pure Python code is not possible. Both the ``showarning()``
3543 and ``formatwarning()`` gain an optional 'line' argument which is
3544 not called by default for backwards-compatibility reasons. Setting
3545 ``warnings.showwarning()`` to an implementation that lacks support
3546 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003588- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003589 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003609- Issue #2550: The approach used by client/server code for obtaining
3610 ports to listen on in network-oriented tests has been refined in an
3611 effort to facilitate running multiple instances of the entire
3612 regression test suite in parallel without issue.
3613 test_support.bind_port() has been fixed such that it will always
3614 return a unique port -- which wasn't always the case with the
3615 previous implementation, especially if socket options had been set
3616 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3617 new implementation of bind_port() will actually raise an exception
3618 if it is passed an AF_INET/SOCK_STREAM socket with either the
3619 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3620 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3621 the socket it's been passed. This currently only applies to
3622 Windows. This option prevents any other sockets from binding to the
3623 host/port we've bound to, thus removing the possibility of the
3624 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3625 when a second SOCK_STREAM socket binds and accepts to a host/port
3626 that's already been bound by another socket. The optional preferred
3627 port parameter to bind_port() has been removed. Under no
3628 circumstances should tests be hard coding ports!
3629
3630 test_support.find_unused_port() has also been introduced, which will
3631 pass a temporary socket object to bind_port() in order to obtain an
3632 unused port. The temporary socket object is then closed and
3633 deleted, and the port is returned. This method should only be used
3634 for obtaining an unused port in order to pass to an external program
3635 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3636 a parameter to a server-oriented class that doesn't give you direct
3637 access to the underlying socket used.
3638
3639 Finally, test_support.HOST has been introduced, which should be used
3640 for the host argument of any relevant socket calls (i.e. bind and
3641 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003642
3643 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003644 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003645 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3646 test_asynchat and test_socket_ssl.
3647
Georg Brandl3ee81df2008-05-17 18:14:43 +00003648 It is now possible for multiple instances of the regression test
3649 suite to run in parallel without issue.

3916-----------------
3917
Fred Drakea8ee94b2008-03-01 02:45:07 +00003918- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003919 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003921- Issue #2067: file.__exit__() now calls subclasses' close() method.
3922
3923- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003924
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003925- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003926 issue 215555 for a discussion.
3927
Eric Smitha73fbe72008-02-23 03:09:44 +00003928- Added the future_builtins module, which contains hex() and oct().
3929 These are the PEP 3127 version of these functions, designed to be
3930 compatible with the hex() and oct() builtins from Python 3.0. They
3931 differ slightly in their output formats from the existing, unchanged
3932 Python 2.6 builtins. The expected usage of the future_builtins
3933 module is:
3934 from future_builtins import hex, oct
3935
Eric Smith7ef40bf2008-02-20 23:34:22 +00003936- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3937 exponents for exponents with absolute value < 100. Follows C99
3938 standard. This is a change on Windows, which would use 3 digits.
3939 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3940 so that any alterations it does to the resulting string will be
3941 available in stringlib/formatter.h (for float.__format__).
3942
Eric Smith5a3c1352008-02-19 13:21:56 +00003943- Implemented PEP 3101, Advanced String Formatting. This adds a new
3944 builtin format(); a format() method for str and unicode; a
3945 __format__() method to object, str, unicode, int, long, float, and
3946 datetime; the class string.Formatter; and the C API
3947 PyObject_Format().
3948
Georg Brandl3ee81df2008-05-17 18:14:43 +00003949- Fixed several potential crashes, all caused by specially crafted
3950 __del__ methods exploiting objects in temporarily inconsistent
3951 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003952
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003953- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003954 prevent a possible crash: an Abstract Base Class would try to access
3955 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003956

Georg Brandl3ee81df2008-05-17 18:14:43 +00003960- Clear all free lists during a gc.collect() of the highest generation
3961 in order to allow pymalloc to free more arenas. Python may give back
3962 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003963
Georg Brandl3ee81df2008-05-17 18:14:43 +00003964- Issue #2045: Fix an infinite recursion triggered when printing a
3965 subclass of collections.defaultdict, if its default_factory is set
3966 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003967
Christian Heimesf75dbef2008-02-08 00:11:31 +00003968- Fixed a minor memory leak in dictobject.c. The content of the free
3969 list was not freed on interpreter shutdown.
3970
Georg Brandl21e99f42010-03-07 15:23:59 +00003971- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003972 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003973
Georg Brandl3ee81df2008-05-17 18:14:43 +00003974- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3975 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003976 to compact the internal free lists of pre-allocted ints and floats.
3977
Georg Brandl3ee81df2008-05-17 18:14:43 +00003978- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3979 calls. Python expected the return type int but the fork familie
3980 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003981

3992 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003993
Georg Brandl3ee81df2008-05-17 18:14:43 +00003994- Patch #1473257: generator objects gain a gi_code attribute. This is
3995 the same object as the func_code attribute of the function that
3996 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003997
Georg Brandl3ee81df2008-05-17 18:14:43 +00003998- Issue #1920: "while 0" statements were completely removed by the
3999 compiler, even in the presence of an "else" clause, which is
4000 supposed to be run when the condition is false. Now the compiler
4001 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00004003- A few crashers fixed: weakref_in_del.py (issue #1377858);
4004 loosing_dict_ref.py (issue #1303614, test67.py);
4005 borrowed_ref_[34].py (not in tracker).
4006
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004007- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004008 suppressed while an extension is loaded by calling SetErrorMode in
4009 dynload_win.c. The error is still reported properly.
4010
Georg Brandl3ee81df2008-05-17 18:14:43 +00004011- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004012 several extension methods and modules do not work without unicode
4013 support.
4014
Georg Brandl26543b12008-01-21 18:36:51 +00004015- Issue #1882: when compiling code from a string, encoding cookies in the
4016 second line of code were not always recognized correctly.
4017
Georg Brandl14404b62008-01-19 19:27:05 +00004018- Issue #1679: "0x" was taken as a valid integer literal.
4019
Georg Brandl6caad7d2008-01-26 14:19:22 +00004020- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004021 added.
4022
Christian Heimesc94e2b52008-01-14 04:13:37 +00004023- sys.float_info / PyFloat_GetInfo: The floating point information
4024 object was converted from a dict to a specialized structseq object.
4025
Georg Brandl3ee81df2008-05-17 18:14:43 +00004026- Patch #1816: Added sys.flags structseq. It exposes the status of
4027 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004028
Georg Brandl3ee81df2008-05-17 18:14:43 +00004029- Objects/structseq.c: Implemented new structseq representation. The
4030 patch makes structseqs (e.g. the return value of os.stat) more
4031 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004032
Georg Brandl3ee81df2008-05-17 18:14:43 +00004033- Patch #1700288: added a type attribute cache that caches method
4034 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004035
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004036- Bug #1776: __import__() no longer accepts filenames on any platform.
4037 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004038
Georg Brandlaed6c662008-01-07 17:25:53 +00004039- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4040
Georg Brandl3ee81df2008-05-17 18:14:43 +00004041- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4042 envvar and sys.dont_write_bytecode attribute. All these can be set
4043 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004044
Georg Brandl3ee81df2008-05-17 18:14:43 +00004045- Improve some exception messages when Windows fails to load an
4046 extension module. Now we get for example '%1 is not a valid Win32
4047 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004048
Georg Brandl3ee81df2008-05-17 18:14:43 +00004049- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004051- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4052 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004053
Christian Heimes0a8143f2007-12-18 23:22:54 +00004054- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004055 and INF. float("nan"), float("inf") and float("-inf") now work on
4056 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004057
Georg Brandl3ee81df2008-05-17 18:14:43 +00004058- Compiler now generates simpler and faster code for dictionary
4059 literals. The oparg for BUILD_MAP now indicates an estimated
4060 dictionary size. There is a new opcode, STORE_MAP, for adding
4061 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004062
Georg Brandl3ee81df2008-05-17 18:14:43 +00004063- Issue #1638: %zd configure test fails on Linux.

4079 running, and if the deallocation of its frames somehow calls the
4080 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004081

Georg Brandl3ee81df2008-05-17 18:14:43 +00004090- Patch #1739468: Directories and zipfiles containing a __main__.py
4091 file can now be directly executed by passing their name to the
4092 interpreter. The directory/zipfile is automatically inserted as the
4093 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004094
Georg Brandl3ee81df2008-05-17 18:14:43 +00004095- Issue #1265: Fix a problem with sys.settrace, if the tracing
4096 function uses a generator expression when at the same time the
4097 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004098
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004099- sets and frozensets now have an isdisjoint() method.
4100
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004101- optimize the performance of builtin.sum().
4102
Neal Norwitz44f326e2007-10-05 05:29:17 +00004103- Fix warnings found by the new version of the Coverity checker.
4104
Georg Brandl21e99f42010-03-07 15:23:59 +00004105- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004106 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4107 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004108
Georg Brandl3ee81df2008-05-17 18:14:43 +00004109- Issue #1686386: Tuple's tp_repr did not take into account the
4110 possibility of having a self-referential tuple, which is possible
4111 from C code. Nor did object's tp_str consider that a type's tp_str
4112 could do something that could lead to an inifinite recursion.
4113 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4114 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004115
Georg Brandl3ee81df2008-05-17 18:14:43 +00004116- Issue #1164: It was possible to trigger deadlock when using the
4117 'print' statement to write to a file since the GIL was not released
4118 as needed. Now PyObject_Print() does the right thing along with
4119 various tp_print implementations of the built-in types and those in
4120 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004121
Georg Brandl3ee81df2008-05-17 18:14:43 +00004122- Issue #1147: Exceptions were directly allowing string exceptions in
4123 their throw() method even though string exceptions no longer
4124 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004125
Georg Brandl3ee81df2008-05-17 18:14:43 +00004126- Issue #1096: Prevent a segfault from getting the repr of a very
4127 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004128
Brett Cannon1e534b52007-09-07 04:18:30 +00004129- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004130 PyObject_Call() never calling back out to Python code to trigger
4131 recursion depth updates/checks. Required the creation of a static
4132 RuntimeError instance in case normalizing an exception put the
4133 recursion check value past its limit. Fixes crashers
4134 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004135
Georg Brandl3ee81df2008-05-17 18:14:43 +00004136- Patch #1031213: Decode source line in SyntaxErrors back to its

4140 with %G.
4141
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00004149- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004150 __*__ attributes. (Some already existed, e.g., __doc__ and
4151 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004152
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004153- Add -3 option to the interpreter to warn about features that are
4154 deprecated and will be changed/removed in Python 3.0.
4155
Georg Brandl2134e752007-05-21 20:34:16 +00004156- Patch #1686487: you can now pass any mapping after '**' in function
4157 calls.
4158
Collin Winter62903052007-05-18 23:11:24 +00004159- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004160 "except E as target:". This is to provide forwards compatibility
4161 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004162
Brett Cannon229cee22007-05-05 01:34:02 +00004163- Deprecate BaseException.message as per PEP 352.
4164
Georg Brandl3ee81df2008-05-17 18:14:43 +00004165- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004166 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004167
Vinay Sajip8549ce32007-05-06 17:53:37 +00004168- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004169 setting a plain string, ie don't expand to single letter identifiers.
4170
Raymond Hettinger13936692007-04-11 18:40:58 +00004171- Request #1191699: Slices can now be pickled.
4172
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004173- Request #1193128: str.translate() now allows a None argument for
4174 translations that only remove characters without re-mapping the
4175 remaining characters.
4176
Georg Brandl5cb76c12007-03-21 09:00:39 +00004177- Patch #1682205: a TypeError while unpacking an iterable is no longer
4178 masked by a generic one with the message "unpack non-sequence".
4179
Neal Norwitzaa754b72007-03-21 06:39:48 +00004180- Remove unused file Python/fmod.c.
4181
Guido van Rossum143b5642007-03-23 04:58:42 +00004182- Bug #1683368: The object.__init__() and object.__new__() methods are
4183 now stricter in rejecting excess arguments. The only time when
4184 either allows excess arguments is when it is not overridden and the
4185 other one is. For backwards compatibility, when both are
4186 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004187 warning later). Also, type.__init__() insists on the same signature
4188 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4191 object to complex using its __complex__() method before falling back
4192 to the __float__() method. Therefore, the functions in the cmath
4193 module now can operate on objects that define a __complex__()
4194 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004195
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196- Patch #1623563: allow __class__ assignment for classes with
4197 __slots__. The old and the new class are still required to have the
4198 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004199
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004203- Patch #1462488: Python no longer segfaults when
4204 ``object.__reduce_ex__()`` is called with an object that is faking
4205 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004206
Georg Brandl3ee81df2008-05-17 18:14:43 +00004207- Patch #1680015: Don't modify __slots__ tuple if it contains an

4211
Georg Brandl7b9c5552007-03-12 14:30:05 +00004212- Bug #1678647: write a newline after printing an exception in any
4213 case, even when converting the value to a string failed.
4214
Georg Brandl871f1bc2007-03-12 13:17:36 +00004215- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004216 its argument, if it exists. If not, it will work like before. This
4217 allows customizing the output of dir() in the presence of a
4218 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004219
Collin Winter276887b2007-03-12 16:11:39 +00004220- Patch #922167: Python no longer segfaults when faced with infinitely
4221 self-recursive reload() calls (as reported by bug #742342).
4222
Georg Brandl3ee81df2008-05-17 18:14:43 +00004223- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004226- Patch #1491866: change the complex() constructor to allow
4227 parthensized forms. This means complex(repr(x)) now works instead of
4228 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004229
Georg Brandlaa2321b2007-03-07 00:40:28 +00004230- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004231 makes the filenames the warning module prints much more sensible
4232 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004233
Georg Brandl49aafc92007-03-07 00:34:46 +00004234- Variant of patch #697613: don't exit the interpreter on a SystemExit
4235 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236 variable is given, but break into the interactive interpreter just
4237 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00004238

4740
Facundo Batistad918a652007-04-24 13:54:38 +00004741- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004742 the client's request was successfully received, understood, and
4743 accepted. Now in these cases no error is raised in urllib (issue
4744 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004745

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004752- Added a timeout parameter to the constructor of other protocols
4753 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4754 work started with create_connection() and timeout in httplib, and
4755 closes patch #723312.
4756
Vinay Sajip8549ce32007-05-06 17:53:37 +00004757- Patch #1676823: Added create_connection() to socket.py, which may be
4758 called with a timeout, and use it from httplib (whose HTTPConnection

Facundo Batista07c78be2007-03-23 18:54:07 +00004760
Martin v. Löwis0af33882007-03-23 13:27:15 +00004761- Bug #978833: Revert r50844, as it broke _socketobject.dup.

4781
Georg Brandlf66b6032007-03-14 08:27:52 +00004782- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004783 AttributeError instead of an IOError when the server's response
4784 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004785
Georg Brandl3ee81df2008-05-17 18:14:43 +00004786- Patch #957650: "%var%" environment variable references are now
4787 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00004789
Georg Brandl3ee81df2008-05-17 18:14:43 +00004790- Patch #1429539: pdb now correctly initializes the __main__ module
4791 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004792 correctly now.
4793

4800
Georg Brandl3ee81df2008-05-17 18:14:43 +00004801- Patch #1530482: add pydoc.render_doc() which returns the
4802 documentation for a thing instead of paging it to stdout, which
4803 pydoc.doc() does.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004805- Patch #1533909: the timeit module now accepts callables in addition

4811 parameter which can be set to False to prevent the default
4812 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00004814- Patch #1581073: add a flag to textwrap that prevents the dropping of
4815 whitespace while wrapping.
4816
Georg Brandl92a6bae2007-03-13 17:43:32 +00004817- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004818 are set for invalid interpolation sequences that would lead to
4819 errors on reading back those values.

Collin Winter22c42ba2007-03-10 02:51:26 +00004854

4862 returned string up to the first NUL character.

4873
Georg Brandl3ee81df2008-05-17 18:14:43 +00004874- unittest now verifies more of its assumptions. In particular,
4875 TestCase and TestSuite subclasses (not instances) are no longer
4876 accepted in TestSuite.addTest(). This should cause no
4877 incompatibility since it never made sense with ordinary subclasses
4878 -- the failure just occurred later, with a more cumbersome
4879 exception.

4888 given a unicode argument and os.listdir() returns unicode filenames.
4889
Georg Brandl3ee81df2008-05-17 18:14:43 +00004890- Patch #1673619: setup.py identifies extension modules it doesn't

4892 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005268 time so that opening a database previously created with the DB_DUP
5269 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5270 opens. Specifically: dictionary assignment to a DB object will
5271 replace all values for a given key when the database allows
5272 duplicate values. DB users should use DB.put(k, v) when they want
5273 to store duplicates; not DB[k] = v.

5280 characters with ASCII value less than 32. Also, it correctly quotes
5281 dots only if they occur on a single line, as opposed to the previous
5282 behavior of quoting dots if they are the second character of any
5283 line.
