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

11
12Core and Builtins
13-----------------
14
Philip Jenveyaebbaeb2010-04-06 23:24:45 +000015- Issue #7301: Add environment variable $PYTHONWARNINGS.
16
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000017- Issue #8329: Don't return the same lists from select.select when no fds are
18 changed.
19
Mark Dickinson82791672010-04-06 16:47:55 +000020- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
21 on 64-bit machines. The shift count for either left or right shift is
22 permitted to be up to sys.maxsize.
23
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000024- Ensure that tokenization of identifiers is not affected by locale.
25
Tarek Ziadé00002952010-04-03 08:37:59 +000026- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
27
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000028- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
29
Eric Smithd44b2fc2010-04-02 12:30:56 +000030- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
31 is called with a non-empty format string. This is an effort to
32 future-proof user code. If a derived class does not currently
33 implement __format__ but later adds its own __format__, it would
34 most likely break user code that had supplied a format string. This
35 will be changed to a DeprecationWaring in Python 3.3 and it will be
36 an error in Python 3.4.
37
Antoine Pitroua57df2c2010-03-31 21:32:15 +000038- Issue #8268: Old-style classes (not just instances) now support weak
39 references.
40
Victor Stinner6cbf90f2010-03-25 00:21:53 +000041- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
42 optimizations are disabled when --with-pydebug is used.
43
Victor Stinnerc7790ed2010-03-22 12:36:28 +000044- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000045
Benjamin Peterson96545892010-03-21 20:21:00 +000046- Issue #6474: Make error message from passing an inadequate number of keyword
47 arguments to a function correct.
48
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000049- Issue #8164: Don't allow lambda functions to have a docstring.
50
Victor Stinner66644262010-03-10 22:30:19 +000051- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000052 (SIGINT). If an error occurs while importing the site module, the error is
53 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000054 module.
55
Collin Winter001a3952010-03-18 21:54:01 +000056- Code objects now support weak references.

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +000058Library
59-------
60
Antoine Pitrouf9de5342010-04-05 21:35:07 +000061- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
62 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
63 and `ssl.OPENSSL_VERSION_NUMBER`.
64
Benjamin Peterson76a23c12010-04-04 23:23:22 +000065- Issue #8310: Allow dis to examine new style classes.
66
Mark Dickinson8a950712010-04-03 15:47:46 +000067- Issue #8257: The Decimal construct now accepts a float instance
68 directly, converting that float to a Decimal of equal value:
69
70 >>> Decimal(1.1)
71 Decimal('1.100000000000000088817841970012523233890533447265625')
72
Raymond Hettinger34c35b22010-04-03 10:22:00 +000073- collections.Counter() now supports a subtract() method.
74
Raymond Hettingera551f312010-04-04 18:34:45 +000075- the functools module now has a total_ordering() class decorator
76 to simplify the specifying rich comparisons.
77
Raymond Hettingerbb006cf2010-04-04 21:45:01 +000078- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +000079 old-style comparison functions to new-style key-functions.
80
Mark Dickinson7c63eee2010-04-02 22:27:36 +000081- Issue #8294: The Fraction constructor now accepts Decimal and float
82 instances directly.
83
Mark Dickinsone096e822010-04-02 10:17:07 +000084- Issue #7279: Comparisons involving a Decimal signaling NaN now
85 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000086 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
87 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000088
Mark Dickinson99d80962010-04-02 08:53:22 +000089- Issue #2531: Comparison operations between floats and Decimal
90 instances now return a result based on the numeric values of the
91 operands; previously they returned an arbitrary result based on
92 the relative ordering of id(float) and id(Decimal).
93
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000094- Issue #8233: When run as a script, py_compile.py optionally takes a single
95 argument `-` which tells it to read files to compile from stdin. Each line
96 is read on demand and the named file is compiled immediately. (Original
97 patch by Piotr Ożarowski).
98
99- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
100 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000101
Florent Xicluna58b65662010-03-30 16:29:03 +0000102- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
103 form feed (0x0C) are now considered linebreaks, as specified in Unicode
104 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000105 http://www.unicode.org/reports/tr14/
106
Mark Dickinson9588d992010-03-27 11:14:37 +0000107- Comparisons using one of <, <=, >, >= between a complex instance and
108 a Fractions instance now raise TypeError instead of returning
109 True/False. This makes Fraction <=> complex comparisons consistent with
110 int <=> complex, float <=> complex, and complex <=> complex comparisons.
111
Michael Foorde6410c52010-03-29 20:04:23 +0000112- Addition of ``WeakSet`` to the ``weakref`` module.
113
Vinay Sajipb0623d62010-03-24 14:31:21 +0000114- logging: Added LOG_FTP to SysLogHandler and updated documentation.
115
Florent Xicluna176cda12010-03-22 22:52:11 +0000116- Issue #8205: Remove the "Modules" directory from sys.path when Python is
117 running from the build directory (POSIX only).
118
Florent Xiclunae1f4c922010-03-22 22:45:50 +0000119- Issue #7667: Fix doctest failures with non-ASCII paths.
120
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000121- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
122 didn't support chflags() (for example ZFS under FreeBSD). The error is
123 now silenced.
124
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000125- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
126 deprecated.
127
R. David Murrayc9d1a782010-03-22 15:55:09 +0000128- Issue #7860: platform.uname now reports the correct 'machine' type
129 when Python is running in WOW64 mode on 64 bit Windows.
130
Vinay Sajip804899b2010-03-22 15:29:01 +0000131- logging: Added getChild utility method to Logger and added isEnabledFor
132 method to LoggerAdapter.
133
Vinay Sajip31e928e2010-03-22 13:02:28 +0000134- Issue #8201: logging: Handle situation of non-ASCII and Unicode
135 logger names existing at the same time, causing a Unicode error
136 when configuration code attempted to sort the existing loggers.
137
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000138- Issue #8200: logging: Handle errors when multiprocessing is not
139 fully loaded when logging occurs.
140
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000141- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
142 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
143 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000144
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000145- Issue #8179: Fix macpath.realpath() on a non-existing path.

148
Antoine Pitroud7b731d2010-03-17 22:45:39 +0000149- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support
150 writing into objects supporting the new buffer API, for example bytearrays
151 or memoryviews.
152
Matthias Klose8b411682010-03-16 10:48:52 +0000153- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox

Matthias Klose358e7ff2010-03-15 13:42:23 +0000158- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
159 the locale.
160
Georg Brandlba83f822010-03-14 09:50:54 +0000161- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000162 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000163 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000164
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000165- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000166 for ``TimedRotatingFileHandler`` by using the modification time of an
167 existing log file to compute the next rollover time. If the log file does
168 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000169
Georg Brandlba83f822010-03-14 09:50:54 +0000170- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

177
Georg Brandlba83f822010-03-14 09:50:54 +0000178- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
179 a base64 transfer-encoded payload *after* decoding it; it no longer does.
180 This is a behavior change, so email's minor version number is now bumped, to
181 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000182
Larry Hastings3b958e32010-04-02 11:18:17 +0000183- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is

196
Martin v. Löwis16ea5482010-04-07 11:01:46 +0000197- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
198
Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000199- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.

Jesus Cea6557aac2010-03-22 14:22:26 +0000201- Issue #8156: bsddb module updated to version 4.8.4.
202 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
203 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000204
Matthias Klose817acef2010-03-15 00:02:36 +0000205- Issue #8142: Update libffi to the 3.0.9 release.
206
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000207- Issue #8300: When passing a non-integer argument to struct.pack with any
208 integer format code, struct.pack first attempts to convert the non-integer
209 using its __index__ method. If that method is non-existent or raises
210 TypeError it goes on to try the __int__ method, as described below.
211
Georg Brandlba83f822010-03-14 09:50:54 +0000212- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
213 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
214 argument's __int__ method to convert to an integer before packing. It also
215 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
216 was inconsistent: __int__ was used for some integer codes but not for others,
217 and the set of integer codes for which it was used differed between native
218 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000219
Brian Curtin19479fa2010-04-02 21:51:37 +0000220- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a

251 is now removed (the macro was introduced in 1997!).
252
Larry Hastings402b73f2010-03-25 00:54:54 +0000253- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000254 from Python 3.1. All existing Python CObjects in the main distribution

602Core and Builtins
603-----------------
604
Georg Brandlba83f822010-03-14 09:50:54 +0000605- The ``__complex__()`` method is now looked up on the class of instances to
606 make it consistent with other special methods.

609 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
610
Mark Dickinson1b34d252010-01-01 17:27:30 +0000611- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000612 DeprecationWarning when passed a float argument where an integer was expected.
613 These functions and methods now raise TypeError instead. The majority of the
614 effects of this change are in the extension modules, but some core functions
615 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
616 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000629- Issue #1811: Improve accuracy and cross-platform consistency for true division
630 of integers: the result of a/b is now correctly rounded for ints a and b (at
631 least on IEEE 754 platforms), and in particular does not depend on the
632 internal representation of a long.

640
Georg Brandlba83f822010-03-14 09:50:54 +0000641 These executables now work properly with the arch(1) command: ``arch -ppc
642 python`` will start a universal binary version of python in PPC mode (unlike
643 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000778- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
779 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000780
Georg Brandlba83f822010-03-14 09:50:54 +0000781- Issue #3382: 'F' formatting for float and complex now convert the result to
782 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
783 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000784
Georg Brandlba83f822010-03-14 09:50:54 +0000785- Remove switch from "%f" formatting to "%g" formatting for floats larger than
786 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000787
Georg Brandlba83f822010-03-14 09:50:54 +0000788- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
789 1e-100 used to raise OverflowError, but now gives the requested 120
790 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000791
Georg Brandlba83f822010-03-14 09:50:54 +0000792- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000793
Georg Brandlba83f822010-03-14 09:50:54 +0000794- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000795
Georg Brandlba83f822010-03-14 09:50:54 +0000796- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
797 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000798
Georg Brandlba83f822010-03-14 09:50:54 +0000799- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
800 decimal string that's guaranteed to round back to x under correct rounding
801 (with round-half-to-even rounding mode). Previously it gave a string based on
802 rounding x to 17 decimal digits. repr(x) for a complex number behaves
803 similarly. On platforms where the correctly-rounded strtod and dtoa code is
804 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000805
Georg Brandlba83f822010-03-14 09:50:54 +0000806- Issue #7117: On almost all platforms: float-to-string and string-to-float
807 conversions within Python are now correctly rounded. Places these conversions
808 occur include: str for floats and complex numbers; the float and complex
809 constructors; old-style and new-style numeric formatting; serialization and
810 deserialization of floats and complex numbers using marshal, pickle and json;
811 parsing of float and imaginary literals in Python code; Decimal-to-float
812 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000813
Georg Brandlba83f822010-03-14 09:50:54 +0000814 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
815 providing correctly-rounded strtod and dtoa C functions. This code is
816 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
817 the C compiler. There may be a small number of platforms on which correct
818 operation of this code cannot be guaranteed, so the code is not used: notably,
819 this applies to platforms where the C double format is not IEEE 754 binary64,
820 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
821 and Python's configure script is unable to determine how to change the FPU
822 precision. On these platforms conversions use the platform strtod and dtoa,
823 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000824
Georg Brandlba83f822010-03-14 09:50:54 +0000825- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
826 uses the correctly-rounded string <-> float conversions described above (when
827 available), and so produces correctly rounded results that will display nicely
828 under the float repr. There are two related small changes: (1) round now
829 accepts any class with an ``__index__()`` method for its second argument (but
830 no longer accepts floats for the second argument), and (2) an excessively
831 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
832 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000833
Philip Jenveyfab8be22009-11-17 02:42:26 +0000834- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
835
Georg Brandlba83f822010-03-14 09:50:54 +0000836- Fix several issues with ``compile()``. The input can now contain Windows and
837 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +0000838

Georg Brandlba83f822010-03-14 09:50:54 +0000857- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
858 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +0000859
Georg Brandlba83f822010-03-14 09:50:54 +0000860- Issue #1754094: Improve the stack depth calculation in the compiler. There

Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000866
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000867- Issue #1571184: The Unicode database contains properties for more characters.
868 The tables for code points representing numeric values, white spaces or line
869 breaks are now generated from the official Unicode Character Database files,
870 and include information from the Unihan.txt file.
871

Georg Brandlba83f822010-03-14 09:50:54 +0000979- Issue #5920: For ``float.__format__()``, change the behavior with the empty
980 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
981 but with at least one decimal point and with a default precision
982 of 12. Previously, the behavior the same but with a default precision of 6.
983 This more closely matches ``str()``, and reduces surprises when adding
984 alignment flags to the empty presentation type. This also affects the new
985 complex.__format__ in the same way.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001237- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1238 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

1247 gives improved memory leak detection when running under Valgrind, while taking
1248 advantage of pymalloc at other times.

2415 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2416 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00002471 leak-chasing test runs give sensible results. The previous method of reaping
2472 threads could return successfully while some Thread objects were still
2473 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00002474
Georg Brandlba83f822010-03-14 09:50:54 +00002475- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002615- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2616 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2617 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2618 ``printf`` function, whereas PyString_FromFormat has an independent
2619 implementation and uses "%zd" on all platforms for size_t values.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002631- Issue #3751: str.rpartition would perform a left-partition when called with
2632 a unicode argument.

Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002634- Issue #3683: Fix compilation when --without-threads is given.
2635
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002636- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002637 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002638 was correctly parsed but parsing of subsequent arguments failed.
2639
Vinay Sajip35e3b032008-09-01 14:33:59 +00002640- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002641 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2642 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2643 when given a tuple of classes as second argument, were looking up
2644 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2645 type object.
2646
Neal Norwitz18aa3882008-08-24 05:04:52 +00002647- Fix crashes on memory allocation failure found with failmalloc.

2716 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2717 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002784What's New in Python 2.6 beta 3?
2785================================
2786
Barry Warsaw07a4a382008-08-21 01:15:08 +00002787*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002788
2789Core and Builtins
2790-----------------
2791
Guido van Rossumf8402962008-08-20 15:01:50 +00002792- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2793 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2794 extensions do not automatically benefit from the class attribute
2795 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2796 to their tp_flags field if they care. This is a backwards
2797 compatibility feature; in 3.0, all types will use the cache by
2798 default.
2799
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002800- Keyword arguments can now follow starred arguments. (``f(a, *args,
2801 keyword=23)`` is now valid syntax.)
2802
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002803- ctypes function pointers that are COM methods have a boolean True
2804 value again.
2805
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002806- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2807 by denying s# to parse objects that have a releasebuffer procedure,
2808 and introducing s*.
2809
Georg Brandl1e13ea92008-08-11 09:07:59 +00002810- Issue #3537: Fix an assertion failure when an empty but presized dict
2811 object was stored in the freelist.
2812
Mark Dickinsonb6467572008-08-04 21:30:09 +00002813- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2814 ValueError consistently across platforms.
2815
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002816- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2817 (64bit Unix, for example), unichr() would truncate its argument and return
2818 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2819
Neal Norwitze7d8be82008-07-31 17:17:14 +00002820- Apply security patches from Apple.
2821
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002822- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2823 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2824
Antoine Pitrou92f82162008-07-25 22:22:08 +00002825- Issue #1819: function calls with several named parameters are now on
2826 average 35% faster (as measured by pybench).
2827
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002828- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2829 the python debugger steps into a class statement: the free variables (local
2830 variables defined in an outer scope) would be deleted from the outer scope.
2831
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002832- Issue #2620: Overflow checking when allocating or reallocating memory
2833 was not always being done properly in some python types and extension
2834 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2835 all been updated to perform better checks and places in the code that
2836 would previously leak memory on the error path when such an allocation
2837 failed have been fixed.

2841
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002842- Issue #3612: Added some missing basic types in ctypes.wintypes.
2843
Benjamin Petersone977ad42008-08-20 01:42:01 +00002844- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2845 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2846
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002847- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2848 version reported by these tools does not necessarily follow the python
2849 version numbering scheme, so the module is less strict when parsing it.
2850
Nick Coghlanf70385a2008-08-18 12:42:46 +00002851- Issue #2235: Added Py3k warnings for types which will become unhashable
2852 under the stricter __hash__ inheritance rules in 3.0. Several types
2853 which did not meet the rules for hash invariants and were already
2854 unhashable in 3.0 have now been explicitly flagged as unhashable in
2855 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2856 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2857
Brett Cannon88f801d2008-08-18 00:46:22 +00002858- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2859 imported into the module but exposed as part of the module's API.
2860
Brett Cannon7b96f072008-08-18 00:41:11 +00002861- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2862
Brett Cannon46225e72008-08-18 00:36:52 +00002863- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002865- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2866
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002867- Issue #3575: Incremental decoder's decode function now takes bytearray
2868 by using 's*' instead of 't#'.
2869
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002870- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002871 fails unicode conversion on 2nd parameter. (windows only)
2872
Facundo Batista94f243a2008-08-17 03:38:39 +00002873- Issue 2464. urllib2 now supports a malformation in the URL received
2874 in a redirect.
2875
Brett Cannonabe423e2008-08-16 21:47:07 +00002876- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002877 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002878
Facundo Batistaeb90b782008-08-16 14:44:07 +00002879- Issue #2776: fixed small issue when handling an URL with double slash
2880 after a 302 response in the case of not going through a proxy.
2881
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002882- Issue #2676: in the email package, content-type parsing was hanging on
2883 pathological input because of quadratic or exponential behaviour of a
2884 regular expression.
2885
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002886- Issue #3476: binary buffered reading through the new "io" library is now
2887 thread-safe.
2888
Brett Cannonbf3157b2008-08-14 05:00:03 +00002889- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2890 since mimetools itself is deprecated. Because modules are cached, all
2891 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2892
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002893- Issue #3134: shutil referenced undefined WindowsError symbol.
2894
Robert Schuppenies14646332008-08-10 11:01:53 +00002895- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2896 menu entries were not deleted.
2897
Brett Cannon83e81842008-08-09 23:30:55 +00002898- Copied the implementation of reduce() to _functools.reduce() to have a
2899 version that did not raise a DeprecationWarning under -3.
2900
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002901- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2902 a MemoryError rather than silently stop the iteration.
2903
Guido van Rossum59ce9012008-08-09 14:55:34 +00002904- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2905 to _sre.compile() will now be rejected. This should not affect anybody
2906 since the re.compile() function never generates invalid re-bytecode.
2907
Skip Montanaroa032bf42008-08-08 22:52:51 +00002908- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2909 upon first access it can be automatically initialized from the csv file if
2910 it wasn't initialized during instantiation.
2911
Brett Cannon3aa2a492008-08-06 22:28:09 +00002912- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2913 the reload() built-in has been removed.
2914
Brett Cannon7e30b672008-08-04 21:52:25 +00002915- Changed code in the following modules/packages to remove warnings raised

2984-----------------
2985
Georg Brandl3e483f62008-07-16 22:57:41 +00002986- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2987 its methods now allow for items objects that can be converted to
2988 an integer using operator.index().
2989
Mark Dickinson64b7e502008-07-16 09:40:03 +00002990- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2991 produced a ValueError instead of giving the correct float.
2992
Eric Smitha5fa5a22008-07-16 00:11:49 +00002993- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2994 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2995
Mark Dickinson7103aa42008-07-15 19:08:33 +00002996- Issue #3008: the float type has a new instance method 'float.hex'
2997 and a new class method 'float.fromhex' to convert floating-point
2998 numbers to and from hexadecimal strings, respectively.
2999
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003000- Issue #2235: __hash__ is once again inherited by default. To allow
3001 collections.Hashable to remain meaningful in the presence of the
3002 default hash implementation (object.__hash__), it is now possible
3003 to explicit block inheritance of hash by setting __hash__=None at
3004 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3005 level.
3006
Nick Coghlanb028f502008-07-13 14:52:36 +00003007- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3008 the parent module cannot be found while performing an absolute import.
3009 This means that an incorrectly defined __package__ attribute will
3010 now only prevent relative imports in that module rather than causing
3011 all imports from that module to fail.
3012
Nick Coghlan14ff9942008-07-08 14:21:42 +00003013- Issue #2517: Allow unicode messages in Exceptions again by correctly
3014 bypassing the instance dictionary when looking up __unicode__ on
3015 new-style classes.

3023 another thread's dictionary.
3024
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003025- Issue #3004: Minor change to slice.indices(): the start and stop
3026 arguments are now treated identically, making the behaviour easier
3027 to describe and understand. For example, slice(None, -10,
3028 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3029 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3030 10, -1).
3031
Georg Brandl278fc502008-07-19 12:46:12 +00003032- Issue #3219: Calling a function with repeated keyword arguments,
3033 f(a=2, a=23), would not cause a syntax error. This was a regression
3034 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003072- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3073 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003074 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003075 content-length. The problem had been corrected in the 2.4 branch, but never
3076 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003091- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3092 handling is now the same as that of other special attributes like __name__).
3093
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003094- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00003484 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003485
3486 This is controlled by the configure argument ``--with-universal-archs``:
3487
3488 - ``--with-universal-archs=all``: install 4-way universal
3489
3490 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3491
3492 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3493
3494 This option should be used in combination with ``--enable-universalsdk=``.
3495
3496 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3501
Georg Brandl74a1dea2008-05-28 11:21:39 +00003502- Add ``PyType_Modified()`` as a public API to clear the type cache.
3503
3504- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003505
3506- The PyString functions have been renamed to PyBytes. A batch of
3507 defines were added so that the linker still sees the original
3508 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003546- Issue #1631171: Re-implement the 'warnings' module in C (the
3547 original Python code has been kept as backup). This will allow for
3548 using the 'warning's machinery in such places as the parser where
3549 use of pure Python code is not possible. Both the ``showarning()``
3550 and ``formatwarning()`` gain an optional 'line' argument which is
3551 not called by default for backwards-compatibility reasons. Setting
3552 ``warnings.showwarning()`` to an implementation that lacks support
3553 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003595- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003596 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003616- Issue #2550: The approach used by client/server code for obtaining
3617 ports to listen on in network-oriented tests has been refined in an
3618 effort to facilitate running multiple instances of the entire
3619 regression test suite in parallel without issue.
3620 test_support.bind_port() has been fixed such that it will always
3621 return a unique port -- which wasn't always the case with the
3622 previous implementation, especially if socket options had been set
3623 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3624 new implementation of bind_port() will actually raise an exception
3625 if it is passed an AF_INET/SOCK_STREAM socket with either the
3626 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3627 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3628 the socket it's been passed. This currently only applies to
3629 Windows. This option prevents any other sockets from binding to the
3630 host/port we've bound to, thus removing the possibility of the
3631 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3632 when a second SOCK_STREAM socket binds and accepts to a host/port
3633 that's already been bound by another socket. The optional preferred
3634 port parameter to bind_port() has been removed. Under no
3635 circumstances should tests be hard coding ports!
3636
3637 test_support.find_unused_port() has also been introduced, which will
3638 pass a temporary socket object to bind_port() in order to obtain an
3639 unused port. The temporary socket object is then closed and
3640 deleted, and the port is returned. This method should only be used
3641 for obtaining an unused port in order to pass to an external program
3642 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3643 a parameter to a server-oriented class that doesn't give you direct
3644 access to the underlying socket used.
3645
3646 Finally, test_support.HOST has been introduced, which should be used
3647 for the host argument of any relevant socket calls (i.e. bind and
3648 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003649
3650 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003651 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003652 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3653 test_asynchat and test_socket_ssl.
3654
Georg Brandl3ee81df2008-05-17 18:14:43 +00003655 It is now possible for multiple instances of the regression test
3656 suite to run in parallel without issue.

3923-----------------
3924
Fred Drakea8ee94b2008-03-01 02:45:07 +00003925- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003926 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003931
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003932- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003933 issue 215555 for a discussion.
3934
Eric Smitha73fbe72008-02-23 03:09:44 +00003935- Added the future_builtins module, which contains hex() and oct().
3936 These are the PEP 3127 version of these functions, designed to be
3937 compatible with the hex() and oct() builtins from Python 3.0. They
3938 differ slightly in their output formats from the existing, unchanged
3939 Python 2.6 builtins. The expected usage of the future_builtins
3940 module is:
3941 from future_builtins import hex, oct
3942
Eric Smith7ef40bf2008-02-20 23:34:22 +00003943- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3944 exponents for exponents with absolute value < 100. Follows C99
3945 standard. This is a change on Windows, which would use 3 digits.
3946 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3947 so that any alterations it does to the resulting string will be
3948 available in stringlib/formatter.h (for float.__format__).
3949
Eric Smith5a3c1352008-02-19 13:21:56 +00003950- Implemented PEP 3101, Advanced String Formatting. This adds a new
3951 builtin format(); a format() method for str and unicode; a
3952 __format__() method to object, str, unicode, int, long, float, and
3953 datetime; the class string.Formatter; and the C API
3954 PyObject_Format().
3955
Georg Brandl3ee81df2008-05-17 18:14:43 +00003956- Fixed several potential crashes, all caused by specially crafted
3957 __del__ methods exploiting objects in temporarily inconsistent
3958 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003959
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003960- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003961 prevent a possible crash: an Abstract Base Class would try to access
3962 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003963

Georg Brandl3ee81df2008-05-17 18:14:43 +00003967- Clear all free lists during a gc.collect() of the highest generation
3968 in order to allow pymalloc to free more arenas. Python may give back
3969 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003970
Georg Brandl3ee81df2008-05-17 18:14:43 +00003971- Issue #2045: Fix an infinite recursion triggered when printing a
3972 subclass of collections.defaultdict, if its default_factory is set
3973 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003974
Christian Heimesf75dbef2008-02-08 00:11:31 +00003975- Fixed a minor memory leak in dictobject.c. The content of the free
3976 list was not freed on interpreter shutdown.
3977
Georg Brandl21e99f42010-03-07 15:23:59 +00003978- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003979 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003980
Georg Brandl3ee81df2008-05-17 18:14:43 +00003981- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3982 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003983 to compact the internal free lists of pre-allocted ints and floats.
3984
Georg Brandl3ee81df2008-05-17 18:14:43 +00003985- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3986 calls. Python expected the return type int but the fork familie
3987 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003988

3999 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004000
Georg Brandl3ee81df2008-05-17 18:14:43 +00004001- Patch #1473257: generator objects gain a gi_code attribute. This is

Georg Brandl3ee81df2008-05-17 18:14:43 +00004005- Issue #1920: "while 0" statements were completely removed by the
4006 compiler, even in the presence of an "else" clause, which is
4007 supposed to be run when the condition is false. Now the compiler
4008 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00004010- A few crashers fixed: weakref_in_del.py (issue #1377858);
4011 loosing_dict_ref.py (issue #1303614, test67.py);
4012 borrowed_ref_[34].py (not in tracker).
4013
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004014- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004015 suppressed while an extension is loaded by calling SetErrorMode in
4016 dynload_win.c. The error is still reported properly.
4017
Georg Brandl3ee81df2008-05-17 18:14:43 +00004018- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004019 several extension methods and modules do not work without unicode
4020 support.
4021
Georg Brandl26543b12008-01-21 18:36:51 +00004022- Issue #1882: when compiling code from a string, encoding cookies in the
4023 second line of code were not always recognized correctly.
4024
Georg Brandl14404b62008-01-19 19:27:05 +00004025- Issue #1679: "0x" was taken as a valid integer literal.
4026
Georg Brandl6caad7d2008-01-26 14:19:22 +00004027- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004028 added.
4029
Christian Heimesc94e2b52008-01-14 04:13:37 +00004030- sys.float_info / PyFloat_GetInfo: The floating point information
4031 object was converted from a dict to a specialized structseq object.
4032
Georg Brandl3ee81df2008-05-17 18:14:43 +00004033- Patch #1816: Added sys.flags structseq. It exposes the status of
4034 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004035
Georg Brandl3ee81df2008-05-17 18:14:43 +00004036- Objects/structseq.c: Implemented new structseq representation. The
4037 patch makes structseqs (e.g. the return value of os.stat) more
4038 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004039
Georg Brandl3ee81df2008-05-17 18:14:43 +00004040- Patch #1700288: added a type attribute cache that caches method
4041 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004042
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004043- Bug #1776: __import__() no longer accepts filenames on any platform.
4044 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004045
Georg Brandlaed6c662008-01-07 17:25:53 +00004046- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4047
Georg Brandl3ee81df2008-05-17 18:14:43 +00004048- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4049 envvar and sys.dont_write_bytecode attribute. All these can be set
4050 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004051
Georg Brandl3ee81df2008-05-17 18:14:43 +00004052- Improve some exception messages when Windows fails to load an
4053 extension module. Now we get for example '%1 is not a valid Win32
4054 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004055

Christian Heimes0a8143f2007-12-18 23:22:54 +00004061- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004062 and INF. float("nan"), float("inf") and float("-inf") now work on
4063 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004064
Georg Brandl3ee81df2008-05-17 18:14:43 +00004065- Compiler now generates simpler and faster code for dictionary
4066 literals. The oparg for BUILD_MAP now indicates an estimated
4067 dictionary size. There is a new opcode, STORE_MAP, for adding
4068 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004097- Patch #1739468: Directories and zipfiles containing a __main__.py
4098 file can now be directly executed by passing their name to the
4099 interpreter. The directory/zipfile is automatically inserted as the
4100 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004101
Georg Brandl3ee81df2008-05-17 18:14:43 +00004102- Issue #1265: Fix a problem with sys.settrace, if the tracing
4103 function uses a generator expression when at the same time the
4104 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004105
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004106- sets and frozensets now have an isdisjoint() method.
4107
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004108- optimize the performance of builtin.sum().
4109
Neal Norwitz44f326e2007-10-05 05:29:17 +00004110- Fix warnings found by the new version of the Coverity checker.
4111
Georg Brandl21e99f42010-03-07 15:23:59 +00004112- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004113 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4114 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004115
Georg Brandl3ee81df2008-05-17 18:14:43 +00004116- Issue #1686386: Tuple's tp_repr did not take into account the
4117 possibility of having a self-referential tuple, which is possible
4118 from C code. Nor did object's tp_str consider that a type's tp_str
4119 could do something that could lead to an inifinite recursion.
4120 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4121 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004122
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123- Issue #1164: It was possible to trigger deadlock when using the
4124 'print' statement to write to a file since the GIL was not released
4125 as needed. Now PyObject_Print() does the right thing along with
4126 various tp_print implementations of the built-in types and those in
4127 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004128
Georg Brandl3ee81df2008-05-17 18:14:43 +00004129- Issue #1147: Exceptions were directly allowing string exceptions in
4130 their throw() method even though string exceptions no longer
4131 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00004135
Brett Cannon1e534b52007-09-07 04:18:30 +00004136- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004137 PyObject_Call() never calling back out to Python code to trigger
4138 recursion depth updates/checks. Required the creation of a static
4139 RuntimeError instance in case normalizing an exception put the
4140 recursion check value past its limit. Fixes crashers
4141 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004142
Georg Brandl3ee81df2008-05-17 18:14:43 +00004143- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004156- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004157 __*__ attributes. (Some already existed, e.g., __doc__ and
4158 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004159
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004160- Add -3 option to the interpreter to warn about features that are
4161 deprecated and will be changed/removed in Python 3.0.
4162
Georg Brandl2134e752007-05-21 20:34:16 +00004163- Patch #1686487: you can now pass any mapping after '**' in function
4164 calls.
4165
Collin Winter62903052007-05-18 23:11:24 +00004166- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004167 "except E as target:". This is to provide forwards compatibility
4168 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004169
Brett Cannon229cee22007-05-05 01:34:02 +00004170- Deprecate BaseException.message as per PEP 352.
4171
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004173 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004174
Vinay Sajip8549ce32007-05-06 17:53:37 +00004175- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004176 setting a plain string, ie don't expand to single letter identifiers.
4177
Raymond Hettinger13936692007-04-11 18:40:58 +00004178- Request #1191699: Slices can now be pickled.
4179
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004180- Request #1193128: str.translate() now allows a None argument for
4181 translations that only remove characters without re-mapping the
4182 remaining characters.
4183
Georg Brandl5cb76c12007-03-21 09:00:39 +00004184- Patch #1682205: a TypeError while unpacking an iterable is no longer
4185 masked by a generic one with the message "unpack non-sequence".
4186
Neal Norwitzaa754b72007-03-21 06:39:48 +00004187- Remove unused file Python/fmod.c.
4188
Guido van Rossum143b5642007-03-23 04:58:42 +00004189- Bug #1683368: The object.__init__() and object.__new__() methods are
4190 now stricter in rejecting excess arguments. The only time when
4191 either allows excess arguments is when it is not overridden and the
4192 other one is. For backwards compatibility, when both are
4193 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004194 warning later). Also, type.__init__() insists on the same signature
4195 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4198 object to complex using its __complex__() method before falling back
4199 to the __float__() method. Therefore, the functions in the cmath
4200 module now can operate on objects that define a __complex__()
4201 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004202
Georg Brandl3ee81df2008-05-17 18:14:43 +00004203- Patch #1623563: allow __class__ assignment for classes with
4204 __slots__. The old and the new class are still required to have the
4205 same slot names.

4211 ``object.__reduce_ex__()`` is called with an object that is faking
4212 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004213
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214- Patch #1680015: Don't modify __slots__ tuple if it contains an

4218
Georg Brandl7b9c5552007-03-12 14:30:05 +00004219- Bug #1678647: write a newline after printing an exception in any
4220 case, even when converting the value to a string failed.
4221
Georg Brandl871f1bc2007-03-12 13:17:36 +00004222- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004223 its argument, if it exists. If not, it will work like before. This
4224 allows customizing the output of dir() in the presence of a
4225 __getattr__().

4229
Georg Brandl3ee81df2008-05-17 18:14:43 +00004230- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004233- Patch #1491866: change the complex() constructor to allow
4234 parthensized forms. This means complex(repr(x)) now works instead of
4235 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004236
Georg Brandlaa2321b2007-03-07 00:40:28 +00004237- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004238 makes the filenames the warning module prints much more sensible
4239 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004240
Georg Brandl49aafc92007-03-07 00:34:46 +00004241- Variant of patch #697613: don't exit the interpreter on a SystemExit

Facundo Batistad918a652007-04-24 13:54:38 +00004748- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004749 the client's request was successfully received, understood, and
4750 accepted. Now in these cases no error is raised in urllib (issue

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004759- Added a timeout parameter to the constructor of other protocols
4760 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4761 work started with create_connection() and timeout in httplib, and
4762 closes patch #723312.
4763
Vinay Sajip8549ce32007-05-06 17:53:37 +00004764- Patch #1676823: Added create_connection() to socket.py, which may be

Facundo Batista07c78be2007-03-23 18:54:07 +00004767
Martin v. Löwis0af33882007-03-23 13:27:15 +00004768- Bug #978833: Revert r50844, as it broke _socketobject.dup.

4788

Georg Brandl3ee81df2008-05-17 18:14:43 +00004790 AttributeError instead of an IOError when the server's response
4791 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004792
Georg Brandl3ee81df2008-05-17 18:14:43 +00004793- Patch #957650: "%var%" environment variable references are now
4794 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00004797- Patch #1429539: pdb now correctly initializes the __main__ module
4798 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004799 correctly now.
4800

4807
Georg Brandl3ee81df2008-05-17 18:14:43 +00004808- Patch #1530482: add pydoc.render_doc() which returns the
4809 documentation for a thing instead of paging it to stdout, which

Georg Brandl9e6b4702007-03-13 18:15:41 +00004821- Patch #1581073: add a flag to textwrap that prevents the dropping of

4823
Georg Brandl92a6bae2007-03-13 17:43:32 +00004824- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004825 are set for invalid interpolation sequences that would lead to
4826 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004827

Collin Winter22c42ba2007-03-10 02:51:26 +00004861

4869 returned string up to the first NUL character.

4880
Georg Brandl3ee81df2008-05-17 18:14:43 +00004881- unittest now verifies more of its assumptions. In particular,
4882 TestCase and TestSuite subclasses (not instances) are no longer
4883 accepted in TestSuite.addTest(). This should cause no
4884 incompatibility since it never made sense with ordinary subclasses
4885 -- the failure just occurred later, with a more cumbersome
4886 exception.

4895 given a unicode argument and os.listdir() returns unicode filenames.
4896
Georg Brandl3ee81df2008-05-17 18:14:43 +00004897- Patch #1673619: setup.py identifies extension modules it doesn't

4899 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005274- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00005275 time so that opening a database previously created with the DB_DUP
5276 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5277 opens. Specifically: dictionary assignment to a DB object will
5278 replace all values for a given key when the database allows
5279 duplicate values. DB users should use DB.put(k, v) when they want
5280 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005281

5287 characters with ASCII value less than 32. Also, it correctly quotes
5288 dots only if they occur on a single line, as opposed to the previous
5289 behavior of quoting dots if they are the second character of any
5290 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005291
