Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00007What's New in Python 2.7 beta 1?
8================================
9
10*Release date: XXXX-XX-XX*
11
12Core and Builtins
13-----------------
14
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.
146
Florent Xicluna2e0a53f2010-03-18 21:50:06 +0000147- Issue #8024: Update the Unicode database to 5.2.
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

Florent Xicluna47627d52010-03-08 15:20:28 +0000176 classes.
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

195-----------------
196
Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000197- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
198
Jesus Cea6557aac2010-03-22 14:22:26 +0000199- Issue #8156: bsddb module updated to version 4.8.4.
200 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
201 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000202
Matthias Klose817acef2010-03-15 00:02:36 +0000203- Issue #8142: Update libffi to the 3.0.9 release.
204
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000205- Issue #8300: When passing a non-integer argument to struct.pack with any
206 integer format code, struct.pack first attempts to convert the non-integer
207 using its __index__ method. If that method is non-existent or raises
208 TypeError it goes on to try the __int__ method, as described below.
209
Georg Brandlba83f822010-03-14 09:50:54 +0000210- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
211 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
212 argument's __int__ method to convert to an integer before packing. It also
213 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
214 was inconsistent: __int__ was used for some integer codes but not for others,
215 and the set of integer codes for which it was used differed between native
216 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000217
Brian Curtin19479fa2010-04-02 21:51:37 +0000218- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a

223
Georg Brandlba83f822010-03-14 09:50:54 +0000224- Issue #7993: Add a test of IO packet processing bandwidth to ccbench. It
225 measures the number of UDP packets processed per second depending on the
226 number of background CPU-bound Python threads.
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000227

249 is now removed (the macro was introduced in 1997!).
250
Larry Hastings402b73f2010-03-25 00:54:54 +0000251- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000252 from Python 3.1. All existing Python CObjects in the main distribution
253 have been converted to capsules. To address backwards-compatibility
254 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

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

600Core and Builtins
601-----------------
602
Georg Brandlba83f822010-03-14 09:50:54 +0000603- The ``__complex__()`` method is now looked up on the class of instances to
604 make it consistent with other special methods.

608
Mark Dickinson1b34d252010-01-01 17:27:30 +0000609- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000610 DeprecationWarning when passed a float argument where an integer was expected.
611 These functions and methods now raise TypeError instead. The majority of the
612 effects of this change are in the extension modules, but some core functions
613 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
614 and many unicode/str methods.

628 of integers: the result of a/b is now correctly rounded for ints a and b (at
629 least on IEEE 754 platforms), and in particular does not depend on the
630 internal representation of a long.

638
Georg Brandlba83f822010-03-14 09:50:54 +0000639 These executables now work properly with the arch(1) command: ``arch -ppc
640 python`` will start a universal binary version of python in PPC mode (unlike
641 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000776- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
777 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000778
Georg Brandlba83f822010-03-14 09:50:54 +0000779- Issue #3382: 'F' formatting for float and complex now convert the result to
780 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
781 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000782
Georg Brandlba83f822010-03-14 09:50:54 +0000783- Remove switch from "%f" formatting to "%g" formatting for floats larger than
784 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000785
Georg Brandlba83f822010-03-14 09:50:54 +0000786- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
787 1e-100 used to raise OverflowError, but now gives the requested 120
788 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000789
Georg Brandlba83f822010-03-14 09:50:54 +0000790- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000791
Georg Brandlba83f822010-03-14 09:50:54 +0000792- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000793
Georg Brandlba83f822010-03-14 09:50:54 +0000794- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
795 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000796
Georg Brandlba83f822010-03-14 09:50:54 +0000797- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
798 decimal string that's guaranteed to round back to x under correct rounding
799 (with round-half-to-even rounding mode). Previously it gave a string based on
800 rounding x to 17 decimal digits. repr(x) for a complex number behaves
801 similarly. On platforms where the correctly-rounded strtod and dtoa code is
802 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000803
Georg Brandlba83f822010-03-14 09:50:54 +0000804- Issue #7117: On almost all platforms: float-to-string and string-to-float
805 conversions within Python are now correctly rounded. Places these conversions
806 occur include: str for floats and complex numbers; the float and complex
807 constructors; old-style and new-style numeric formatting; serialization and
808 deserialization of floats and complex numbers using marshal, pickle and json;
809 parsing of float and imaginary literals in Python code; Decimal-to-float
810 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000811
Georg Brandlba83f822010-03-14 09:50:54 +0000812 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
813 providing correctly-rounded strtod and dtoa C functions. This code is
814 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
815 the C compiler. There may be a small number of platforms on which correct
816 operation of this code cannot be guaranteed, so the code is not used: notably,
817 this applies to platforms where the C double format is not IEEE 754 binary64,
818 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
819 and Python's configure script is unable to determine how to change the FPU
820 precision. On these platforms conversions use the platform strtod and dtoa,
821 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000822
Georg Brandlba83f822010-03-14 09:50:54 +0000823- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
824 uses the correctly-rounded string <-> float conversions described above (when
825 available), and so produces correctly rounded results that will display nicely
826 under the float repr. There are two related small changes: (1) round now
827 accepts any class with an ``__index__()`` method for its second argument (but
828 no longer accepts floats for the second argument), and (2) an excessively
829 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
830 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000831
Philip Jenveyfab8be22009-11-17 02:42:26 +0000832- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
833
Georg Brandlba83f822010-03-14 09:50:54 +0000834- Fix several issues with ``compile()``. The input can now contain Windows and
835 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +0000836
Georg Brandlba83f822010-03-14 09:50:54 +0000837- Remove length limitation when constructing a complex number from a unicode
838 string.

Georg Brandlba83f822010-03-14 09:50:54 +0000855- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
856 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +0000857
Georg Brandlba83f822010-03-14 09:50:54 +0000858- Issue #1754094: Improve the stack depth calculation in the compiler. There

Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000864
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000865- Issue #1571184: The Unicode database contains properties for more characters.
866 The tables for code points representing numeric values, white spaces or line
867 breaks are now generated from the official Unicode Character Database files,
868 and include information from the Unihan.txt file.
869

Georg Brandlba83f822010-03-14 09:50:54 +0000977- Issue #5920: For ``float.__format__()``, change the behavior with the empty
978 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
979 but with at least one decimal point and with a default precision
980 of 12. Previously, the behavior the same but with a default precision of 6.
981 This more closely matches ``str()``, and reduces surprises when adding
982 alignment flags to the empty presentation type. This also affects the new
983 complex.__format__ in the same way.

1245 gives improved memory leak detection when running under Valgrind, while taking
1246 advantage of pymalloc at other times.

2413 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2414 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00002469 leak-chasing test runs give sensible results. The previous method of reaping
2470 threads could return successfully while some Thread objects were still
2471 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00002472
Georg Brandlba83f822010-03-14 09:50:54 +00002473- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002613- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

2615 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2616 ``printf`` function, whereas PyString_FromFormat has an independent
2617 implementation and uses "%zd" on all platforms for size_t values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002634- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002635 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002636 was correctly parsed but parsing of subsequent arguments failed.
2637
Vinay Sajip35e3b032008-09-01 14:33:59 +00002638- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002639 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2640 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2641 when given a tuple of classes as second argument, were looking up
2642 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2643 type object.
2644
Neal Norwitz18aa3882008-08-24 05:04:52 +00002645- Fix crashes on memory allocation failure found with failmalloc.

2714 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2715 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002782What's New in Python 2.6 beta 3?
2783================================
2784
Barry Warsaw07a4a382008-08-21 01:15:08 +00002785*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002786
2787Core and Builtins
2788-----------------
2789
Guido van Rossumf8402962008-08-20 15:01:50 +00002790- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2791 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2792 extensions do not automatically benefit from the class attribute
2793 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2794 to their tp_flags field if they care. This is a backwards
2795 compatibility feature; in 3.0, all types will use the cache by
2796 default.
2797
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002798- Keyword arguments can now follow starred arguments. (``f(a, *args,
2799 keyword=23)`` is now valid syntax.)
2800
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002801- ctypes function pointers that are COM methods have a boolean True
2802 value again.
2803
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002804- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2805 by denying s# to parse objects that have a releasebuffer procedure,
2806 and introducing s*.
2807
Georg Brandl1e13ea92008-08-11 09:07:59 +00002808- Issue #3537: Fix an assertion failure when an empty but presized dict
2809 object was stored in the freelist.
2810
Mark Dickinsonb6467572008-08-04 21:30:09 +00002811- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2812 ValueError consistently across platforms.
2813
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002814- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2815 (64bit Unix, for example), unichr() would truncate its argument and return
2816 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2817
Neal Norwitze7d8be82008-07-31 17:17:14 +00002818- Apply security patches from Apple.
2819
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002820- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2821 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2822
Antoine Pitrou92f82162008-07-25 22:22:08 +00002823- Issue #1819: function calls with several named parameters are now on
2824 average 35% faster (as measured by pybench).
2825
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002826- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2827 the python debugger steps into a class statement: the free variables (local
2828 variables defined in an outer scope) would be deleted from the outer scope.
2829
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002830- Issue #2620: Overflow checking when allocating or reallocating memory
2831 was not always being done properly in some python types and extension
2832 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2833 all been updated to perform better checks and places in the code that
2834 would previously leak memory on the error path when such an allocation
2835 failed have been fixed.

2839
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002840- Issue #3612: Added some missing basic types in ctypes.wintypes.
2841
Benjamin Petersone977ad42008-08-20 01:42:01 +00002842- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2843 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2844
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002845- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2846 version reported by these tools does not necessarily follow the python
2847 version numbering scheme, so the module is less strict when parsing it.
2848
Nick Coghlanf70385a2008-08-18 12:42:46 +00002849- Issue #2235: Added Py3k warnings for types which will become unhashable
2850 under the stricter __hash__ inheritance rules in 3.0. Several types
2851 which did not meet the rules for hash invariants and were already
2852 unhashable in 3.0 have now been explicitly flagged as unhashable in
2853 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2854 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2855
Brett Cannon88f801d2008-08-18 00:46:22 +00002856- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2857 imported into the module but exposed as part of the module's API.
2858
Brett Cannon7b96f072008-08-18 00:41:11 +00002859- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2860
Brett Cannon46225e72008-08-18 00:36:52 +00002861- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002863- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2864
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002865- Issue #3575: Incremental decoder's decode function now takes bytearray
2866 by using 's*' instead of 't#'.
2867
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002868- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002869 fails unicode conversion on 2nd parameter. (windows only)
2870
Facundo Batista94f243a2008-08-17 03:38:39 +00002871- Issue 2464. urllib2 now supports a malformation in the URL received
2872 in a redirect.
2873
Brett Cannonabe423e2008-08-16 21:47:07 +00002874- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002875 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002876
Facundo Batistaeb90b782008-08-16 14:44:07 +00002877- Issue #2776: fixed small issue when handling an URL with double slash
2878 after a 302 response in the case of not going through a proxy.
2879
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002880- Issue #2676: in the email package, content-type parsing was hanging on
2881 pathological input because of quadratic or exponential behaviour of a
2882 regular expression.
2883
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002884- Issue #3476: binary buffered reading through the new "io" library is now
2885 thread-safe.
2886
Brett Cannonbf3157b2008-08-14 05:00:03 +00002887- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2888 since mimetools itself is deprecated. Because modules are cached, all
2889 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2890
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002891- Issue #3134: shutil referenced undefined WindowsError symbol.
2892
Robert Schuppenies14646332008-08-10 11:01:53 +00002893- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2894 menu entries were not deleted.
2895
Brett Cannon83e81842008-08-09 23:30:55 +00002896- Copied the implementation of reduce() to _functools.reduce() to have a
2897 version that did not raise a DeprecationWarning under -3.
2898
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002899- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2900 a MemoryError rather than silently stop the iteration.
2901
Guido van Rossum59ce9012008-08-09 14:55:34 +00002902- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2903 to _sre.compile() will now be rejected. This should not affect anybody
2904 since the re.compile() function never generates invalid re-bytecode.
2905
Skip Montanaroa032bf42008-08-08 22:52:51 +00002906- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2907 upon first access it can be automatically initialized from the csv file if
2908 it wasn't initialized during instantiation.
2909
Brett Cannon3aa2a492008-08-06 22:28:09 +00002910- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2911 the reload() built-in has been removed.
2912
Brett Cannon7e30b672008-08-04 21:52:25 +00002913- Changed code in the following modules/packages to remove warnings raised

2982-----------------
2983
Georg Brandl3e483f62008-07-16 22:57:41 +00002984- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2985 its methods now allow for items objects that can be converted to
2986 an integer using operator.index().
2987
Mark Dickinson64b7e502008-07-16 09:40:03 +00002988- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2989 produced a ValueError instead of giving the correct float.
2990
Eric Smitha5fa5a22008-07-16 00:11:49 +00002991- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2992 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2993
Mark Dickinson7103aa42008-07-15 19:08:33 +00002994- Issue #3008: the float type has a new instance method 'float.hex'
2995 and a new class method 'float.fromhex' to convert floating-point
2996 numbers to and from hexadecimal strings, respectively.
2997
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002998- Issue #2235: __hash__ is once again inherited by default. To allow
2999 collections.Hashable to remain meaningful in the presence of the
3000 default hash implementation (object.__hash__), it is now possible
3001 to explicit block inheritance of hash by setting __hash__=None at
3002 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3003 level.
3004
Nick Coghlanb028f502008-07-13 14:52:36 +00003005- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3006 the parent module cannot be found while performing an absolute import.
3007 This means that an incorrectly defined __package__ attribute will
3008 now only prevent relative imports in that module rather than causing
3009 all imports from that module to fail.
3010
Nick Coghlan14ff9942008-07-08 14:21:42 +00003011- Issue #2517: Allow unicode messages in Exceptions again by correctly

3021 another thread's dictionary.
3022
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003023- Issue #3004: Minor change to slice.indices(): the start and stop
3024 arguments are now treated identically, making the behaviour easier
3025 to describe and understand. For example, slice(None, -10,
3026 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3027 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3028 10, -1).
3029
Georg Brandl278fc502008-07-19 12:46:12 +00003030- Issue #3219: Calling a function with repeated keyword arguments,
3031 f(a=2, a=23), would not cause a syntax error. This was a regression
3032 from 2.4 caused by the switch to the new compiler.

3043 error when they failed.
3044
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003045- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003070- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3071 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003072 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003073 content-length. The problem had been corrected in the 2.4 branch, but never
3074 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003089- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3090 handling is now the same as that of other special attributes like __name__).
3091
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003092- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00003482 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003483
3484 This is controlled by the configure argument ``--with-universal-archs``:
3485
3486 - ``--with-universal-archs=all``: install 4-way universal
3487
3488 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3489
3490 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3491
3492 This option should be used in combination with ``--enable-universalsdk=``.
3493
3494 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3499
Georg Brandl74a1dea2008-05-28 11:21:39 +00003500- Add ``PyType_Modified()`` as a public API to clear the type cache.
3501
3502- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003503
3504- The PyString functions have been renamed to PyBytes. A batch of
3505 defines were added so that the linker still sees the original
3506 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003544- Issue #1631171: Re-implement the 'warnings' module in C (the
3545 original Python code has been kept as backup). This will allow for
3546 using the 'warning's machinery in such places as the parser where
3547 use of pure Python code is not possible. Both the ``showarning()``
3548 and ``formatwarning()`` gain an optional 'line' argument which is
3549 not called by default for backwards-compatibility reasons. Setting
3550 ``warnings.showwarning()`` to an implementation that lacks support
3551 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003576- The getpass module has been improved on Unix. It now uses /dev/tty
3577 by default and uses stderr instead of stdout. A GetPassWarning is
3578 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003593- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003594 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003614- Issue #2550: The approach used by client/server code for obtaining
3615 ports to listen on in network-oriented tests has been refined in an
3616 effort to facilitate running multiple instances of the entire
3617 regression test suite in parallel without issue.
3618 test_support.bind_port() has been fixed such that it will always
3619 return a unique port -- which wasn't always the case with the
3620 previous implementation, especially if socket options had been set
3621 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3622 new implementation of bind_port() will actually raise an exception
3623 if it is passed an AF_INET/SOCK_STREAM socket with either the
3624 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3625 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3626 the socket it's been passed. This currently only applies to
3627 Windows. This option prevents any other sockets from binding to the
3628 host/port we've bound to, thus removing the possibility of the
3629 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3630 when a second SOCK_STREAM socket binds and accepts to a host/port
3631 that's already been bound by another socket. The optional preferred
3632 port parameter to bind_port() has been removed. Under no
3633 circumstances should tests be hard coding ports!
3634
3635 test_support.find_unused_port() has also been introduced, which will
3636 pass a temporary socket object to bind_port() in order to obtain an
3637 unused port. The temporary socket object is then closed and
3638 deleted, and the port is returned. This method should only be used
3639 for obtaining an unused port in order to pass to an external program
3640 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3641 a parameter to a server-oriented class that doesn't give you direct
3642 access to the underlying socket used.
3643
3644 Finally, test_support.HOST has been introduced, which should be used
3645 for the host argument of any relevant socket calls (i.e. bind and
3646 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003647
3648 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003649 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003650 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3651 test_asynchat and test_socket_ssl.
3652
Georg Brandl3ee81df2008-05-17 18:14:43 +00003653 It is now possible for multiple instances of the regression test
3654 suite to run in parallel without issue.

3921-----------------
3922
Fred Drakea8ee94b2008-03-01 02:45:07 +00003923- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003924 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003929
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003930- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003931 issue 215555 for a discussion.
3932
Eric Smitha73fbe72008-02-23 03:09:44 +00003933- Added the future_builtins module, which contains hex() and oct().
3934 These are the PEP 3127 version of these functions, designed to be
3935 compatible with the hex() and oct() builtins from Python 3.0. They
3936 differ slightly in their output formats from the existing, unchanged
3937 Python 2.6 builtins. The expected usage of the future_builtins
3938 module is:
3939 from future_builtins import hex, oct
3940
Eric Smith7ef40bf2008-02-20 23:34:22 +00003941- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3942 exponents for exponents with absolute value < 100. Follows C99
3943 standard. This is a change on Windows, which would use 3 digits.
3944 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3945 so that any alterations it does to the resulting string will be
3946 available in stringlib/formatter.h (for float.__format__).
3947
Eric Smith5a3c1352008-02-19 13:21:56 +00003948- Implemented PEP 3101, Advanced String Formatting. This adds a new
3949 builtin format(); a format() method for str and unicode; a
3950 __format__() method to object, str, unicode, int, long, float, and
3951 datetime; the class string.Formatter; and the C API
3952 PyObject_Format().
3953
Georg Brandl3ee81df2008-05-17 18:14:43 +00003954- Fixed several potential crashes, all caused by specially crafted
3955 __del__ methods exploiting objects in temporarily inconsistent
3956 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003957
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003958- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003959 prevent a possible crash: an Abstract Base Class would try to access
3960 a slot on a registered virtual subclass.

3966 in order to allow pymalloc to free more arenas. Python may give back
3967 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003968
Georg Brandl3ee81df2008-05-17 18:14:43 +00003969- Issue #2045: Fix an infinite recursion triggered when printing a
3970 subclass of collections.defaultdict, if its default_factory is set
3971 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003972
Christian Heimesf75dbef2008-02-08 00:11:31 +00003973- Fixed a minor memory leak in dictobject.c. The content of the free
3974 list was not freed on interpreter shutdown.
3975
Georg Brandl21e99f42010-03-07 15:23:59 +00003976- Limit free list of method and built-in function objects to 256

3980 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003981 to compact the internal free lists of pre-allocted ints and floats.
3982
Georg Brandl3ee81df2008-05-17 18:14:43 +00003983- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3984 calls. Python expected the return type int but the fork familie
3985 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003986

3997 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003998
Georg Brandl3ee81df2008-05-17 18:14:43 +00003999- Patch #1473257: generator objects gain a gi_code attribute. This is

Georg Brandl3ee81df2008-05-17 18:14:43 +00004003- Issue #1920: "while 0" statements were completely removed by the
4004 compiler, even in the presence of an "else" clause, which is
4005 supposed to be run when the condition is false. Now the compiler
4006 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00004008- A few crashers fixed: weakref_in_del.py (issue #1377858);
4009 loosing_dict_ref.py (issue #1303614, test67.py);
4010 borrowed_ref_[34].py (not in tracker).
4011
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004012- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004013 suppressed while an extension is loaded by calling SetErrorMode in
4014 dynload_win.c. The error is still reported properly.
4015
Georg Brandl3ee81df2008-05-17 18:14:43 +00004016- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004017 several extension methods and modules do not work without unicode
4018 support.
4019
Georg Brandl26543b12008-01-21 18:36:51 +00004020- Issue #1882: when compiling code from a string, encoding cookies in the
4021 second line of code were not always recognized correctly.
4022
Georg Brandl14404b62008-01-19 19:27:05 +00004023- Issue #1679: "0x" was taken as a valid integer literal.
4024
Georg Brandl6caad7d2008-01-26 14:19:22 +00004025- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004026 added.
4027
Christian Heimesc94e2b52008-01-14 04:13:37 +00004028- sys.float_info / PyFloat_GetInfo: The floating point information
4029 object was converted from a dict to a specialized structseq object.
4030
Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Patch #1816: Added sys.flags structseq. It exposes the status of
4032 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004033
Georg Brandl3ee81df2008-05-17 18:14:43 +00004034- Objects/structseq.c: Implemented new structseq representation. The
4035 patch makes structseqs (e.g. the return value of os.stat) more
4036 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004037
Georg Brandl3ee81df2008-05-17 18:14:43 +00004038- Patch #1700288: added a type attribute cache that caches method
4039 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004040
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004041- Bug #1776: __import__() no longer accepts filenames on any platform.
4042 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004043
Georg Brandlaed6c662008-01-07 17:25:53 +00004044- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4045
Georg Brandl3ee81df2008-05-17 18:14:43 +00004046- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4047 envvar and sys.dont_write_bytecode attribute. All these can be set
4048 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004049
Georg Brandl3ee81df2008-05-17 18:14:43 +00004050- Improve some exception messages when Windows fails to load an
4051 extension module. Now we get for example '%1 is not a valid Win32
4052 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004053

Christian Heimes0a8143f2007-12-18 23:22:54 +00004059- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004060 and INF. float("nan"), float("inf") and float("-inf") now work on
4061 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004062
Georg Brandl3ee81df2008-05-17 18:14:43 +00004063- Compiler now generates simpler and faster code for dictionary
4064 literals. The oparg for BUILD_MAP now indicates an estimated
4065 dictionary size. There is a new opcode, STORE_MAP, for adding
4066 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004095- Patch #1739468: Directories and zipfiles containing a __main__.py
4096 file can now be directly executed by passing their name to the
4097 interpreter. The directory/zipfile is automatically inserted as the
4098 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004100- Issue #1265: Fix a problem with sys.settrace, if the tracing
4101 function uses a generator expression when at the same time the
4102 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004103
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004104- sets and frozensets now have an isdisjoint() method.
4105
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004106- optimize the performance of builtin.sum().
4107
Neal Norwitz44f326e2007-10-05 05:29:17 +00004108- Fix warnings found by the new version of the Coverity checker.
4109
Georg Brandl21e99f42010-03-07 15:23:59 +00004110- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004111 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4112 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004113
Georg Brandl3ee81df2008-05-17 18:14:43 +00004114- Issue #1686386: Tuple's tp_repr did not take into account the
4115 possibility of having a self-referential tuple, which is possible
4116 from C code. Nor did object's tp_str consider that a type's tp_str
4117 could do something that could lead to an inifinite recursion.
4118 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4119 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004120
Georg Brandl3ee81df2008-05-17 18:14:43 +00004121- Issue #1164: It was possible to trigger deadlock when using the
4122 'print' statement to write to a file since the GIL was not released
4123 as needed. Now PyObject_Print() does the right thing along with
4124 various tp_print implementations of the built-in types and those in
4125 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004126
Georg Brandl3ee81df2008-05-17 18:14:43 +00004127- Issue #1147: Exceptions were directly allowing string exceptions in
4128 their throw() method even though string exceptions no longer
4129 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00004133
Brett Cannon1e534b52007-09-07 04:18:30 +00004134- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004135 PyObject_Call() never calling back out to Python code to trigger
4136 recursion depth updates/checks. Required the creation of a static
4137 RuntimeError instance in case normalizing an exception put the
4138 recursion check value past its limit. Fixes crashers
4139 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004140

Neal Norwitz0ac60192007-05-27 04:08:54 +00004154- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004155 __*__ attributes. (Some already existed, e.g., __doc__ and
4156 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004157
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004158- Add -3 option to the interpreter to warn about features that are
4159 deprecated and will be changed/removed in Python 3.0.
4160
Georg Brandl2134e752007-05-21 20:34:16 +00004161- Patch #1686487: you can now pass any mapping after '**' in function
4162 calls.
4163
Collin Winter62903052007-05-18 23:11:24 +00004164- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004165 "except E as target:". This is to provide forwards compatibility
4166 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004170- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004171 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004173- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004174 setting a plain string, ie don't expand to single letter identifiers.
4175
Raymond Hettinger13936692007-04-11 18:40:58 +00004176- Request #1191699: Slices can now be pickled.
4177
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004178- Request #1193128: str.translate() now allows a None argument for
4179 translations that only remove characters without re-mapping the
4180 remaining characters.
4181
Georg Brandl5cb76c12007-03-21 09:00:39 +00004182- Patch #1682205: a TypeError while unpacking an iterable is no longer
4183 masked by a generic one with the message "unpack non-sequence".
4184
Neal Norwitzaa754b72007-03-21 06:39:48 +00004185- Remove unused file Python/fmod.c.
4186
Guido van Rossum143b5642007-03-23 04:58:42 +00004187- Bug #1683368: The object.__init__() and object.__new__() methods are
4188 now stricter in rejecting excess arguments. The only time when
4189 either allows excess arguments is when it is not overridden and the
4190 other one is. For backwards compatibility, when both are
4191 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004192 warning later). Also, type.__init__() insists on the same signature
4193 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004194
Georg Brandl3ee81df2008-05-17 18:14:43 +00004195- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4196 object to complex using its __complex__() method before falling back
4197 to the __float__() method. Therefore, the functions in the cmath
4198 module now can operate on objects that define a __complex__()
4199 method.

4209 ``object.__reduce_ex__()`` is called with an object that is faking
4210 its type.

4216
Georg Brandl7b9c5552007-03-12 14:30:05 +00004217- Bug #1678647: write a newline after printing an exception in any
4218 case, even when converting the value to a string failed.
4219
Georg Brandl871f1bc2007-03-12 13:17:36 +00004220- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221 its argument, if it exists. If not, it will work like before. This
4222 allows customizing the output of dir() in the presence of a
4223 __getattr__().

4227
Georg Brandl3ee81df2008-05-17 18:14:43 +00004228- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004231- Patch #1491866: change the complex() constructor to allow
4232 parthensized forms. This means complex(repr(x)) now works instead of
4233 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004234
Georg Brandlaa2321b2007-03-07 00:40:28 +00004235- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236 makes the filenames the warning module prints much more sensible
4237 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004238
Georg Brandl49aafc92007-03-07 00:34:46 +00004239- Variant of patch #697613: don't exit the interpreter on a SystemExit

Facundo Batistad918a652007-04-24 13:54:38 +00004746- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004747 the client's request was successfully received, understood, and
4748 accepted. Now in these cases no error is raised in urllib (issue
4749 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004757- Added a timeout parameter to the constructor of other protocols
4758 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4759 work started with create_connection() and timeout in httplib, and
4760 closes patch #723312.
4761
Vinay Sajip8549ce32007-05-06 17:53:37 +00004762- Patch #1676823: Added create_connection() to socket.py, which may be

Facundo Batista07c78be2007-03-23 18:54:07 +00004765
Martin v. Löwis0af33882007-03-23 13:27:15 +00004766- Bug #978833: Revert r50844, as it broke _socketobject.dup.

4786
Georg Brandlf66b6032007-03-14 08:27:52 +00004787- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004788 AttributeError instead of an IOError when the server's response
4789 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004790

4792 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00004795- Patch #1429539: pdb now correctly initializes the __main__ module
4796 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004797 correctly now.
4798

4805
Georg Brandl3ee81df2008-05-17 18:14:43 +00004806- Patch #1530482: add pydoc.render_doc() which returns the
4807 documentation for a thing instead of paging it to stdout, which

Georg Brandl9e6b4702007-03-13 18:15:41 +00004819- Patch #1581073: add a flag to textwrap that prevents the dropping of

4821
Georg Brandl92a6bae2007-03-13 17:43:32 +00004822- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004823 are set for invalid interpolation sequences that would lead to
4824 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004825

Collin Winter22c42ba2007-03-10 02:51:26 +00004859

4867 returned string up to the first NUL character.

4878
Georg Brandl3ee81df2008-05-17 18:14:43 +00004879- unittest now verifies more of its assumptions. In particular,
4880 TestCase and TestSuite subclasses (not instances) are no longer
4881 accepted in TestSuite.addTest(). This should cause no
4882 incompatibility since it never made sense with ordinary subclasses
4883 -- the failure just occurred later, with a more cumbersome
4884 exception.

4893 given a unicode argument and os.listdir() returns unicode filenames.
4894
Georg Brandl3ee81df2008-05-17 18:14:43 +00004895- Patch #1673619: setup.py identifies extension modules it doesn't

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005272- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00005273 time so that opening a database previously created with the DB_DUP
5274 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5275 opens. Specifically: dictionary assignment to a DB object will
5276 replace all values for a given key when the database allows
5277 duplicate values. DB users should use DB.put(k, v) when they want
5278 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005279

5285 characters with ASCII value less than 32. Also, it correctly quotes
5286 dots only if they occur on a single line, as opposed to the previous
5287 behavior of quoting dots if they are the second character of any
5288 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005289
