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

10*Release date: XXXX-XX-XX*
11
12Core and Builtins
13-----------------
14
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.

60
Martin v. Löwis1b287c72010-04-08 09:47:40 +000061- Issue #8344: Fix test_ttk bug on FreeBSD.
62
Antoine Pitrouf9de5342010-04-05 21:35:07 +000063- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
64 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
65 and `ssl.OPENSSL_VERSION_NUMBER`.
66
Benjamin Peterson76a23c12010-04-04 23:23:22 +000067- Issue #8310: Allow dis to examine new style classes.
68
Mark Dickinson8a950712010-04-03 15:47:46 +000069- Issue #8257: The Decimal construct now accepts a float instance
70 directly, converting that float to a Decimal of equal value:
71
72 >>> Decimal(1.1)
73 Decimal('1.100000000000000088817841970012523233890533447265625')
74
Raymond Hettinger34c35b22010-04-03 10:22:00 +000075- collections.Counter() now supports a subtract() method.
76
Raymond Hettingera551f312010-04-04 18:34:45 +000077- the functools module now has a total_ordering() class decorator
78 to simplify the specifying rich comparisons.
79
Raymond Hettingerbb006cf2010-04-04 21:45:01 +000080- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +000081 old-style comparison functions to new-style key-functions.
82
Mark Dickinson7c63eee2010-04-02 22:27:36 +000083- Issue #8294: The Fraction constructor now accepts Decimal and float
84 instances directly.
85
Mark Dickinsone096e822010-04-02 10:17:07 +000086- Issue #7279: Comparisons involving a Decimal signaling NaN now
87 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000088 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
89 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000090
Mark Dickinson99d80962010-04-02 08:53:22 +000091- Issue #2531: Comparison operations between floats and Decimal
92 instances now return a result based on the numeric values of the
93 operands; previously they returned an arbitrary result based on
94 the relative ordering of id(float) and id(Decimal).
95
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000096- Issue #8233: When run as a script, py_compile.py optionally takes a single
97 argument `-` which tells it to read files to compile from stdin. Each line
98 is read on demand and the named file is compiled immediately. (Original
99 patch by Piotr Ożarowski).
100
101- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
102 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000103
Florent Xicluna58b65662010-03-30 16:29:03 +0000104- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
105 form feed (0x0C) are now considered linebreaks, as specified in Unicode
106 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000107 http://www.unicode.org/reports/tr14/
108
Mark Dickinson9588d992010-03-27 11:14:37 +0000109- Comparisons using one of <, <=, >, >= between a complex instance and
110 a Fractions instance now raise TypeError instead of returning
111 True/False. This makes Fraction <=> complex comparisons consistent with
112 int <=> complex, float <=> complex, and complex <=> complex comparisons.
113
Michael Foorde6410c52010-03-29 20:04:23 +0000114- Addition of ``WeakSet`` to the ``weakref`` module.
115
Vinay Sajipb0623d62010-03-24 14:31:21 +0000116- logging: Added LOG_FTP to SysLogHandler and updated documentation.
117
Florent Xicluna176cda12010-03-22 22:52:11 +0000118- Issue #8205: Remove the "Modules" directory from sys.path when Python is
119 running from the build directory (POSIX only).
120
Florent Xiclunae1f4c922010-03-22 22:45:50 +0000121- Issue #7667: Fix doctest failures with non-ASCII paths.
122
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000123- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
124 didn't support chflags() (for example ZFS under FreeBSD). The error is
125 now silenced.
126
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000127- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
128 deprecated.
129
R. David Murrayc9d1a782010-03-22 15:55:09 +0000130- Issue #7860: platform.uname now reports the correct 'machine' type
131 when Python is running in WOW64 mode on 64 bit Windows.
132
Vinay Sajip804899b2010-03-22 15:29:01 +0000133- logging: Added getChild utility method to Logger and added isEnabledFor
134 method to LoggerAdapter.
135
Vinay Sajip31e928e2010-03-22 13:02:28 +0000136- Issue #8201: logging: Handle situation of non-ASCII and Unicode
137 logger names existing at the same time, causing a Unicode error
138 when configuration code attempted to sort the existing loggers.
139
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000140- Issue #8200: logging: Handle errors when multiprocessing is not
141 fully loaded when logging occurs.
142
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000143- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
144 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
145 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000146
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000147- Issue #8179: Fix macpath.realpath() on a non-existing path.

Antoine Pitroud7b731d2010-03-17 22:45:39 +0000151- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support
152 writing into objects supporting the new buffer API, for example bytearrays
153 or memoryviews.
154
Matthias Klose8b411682010-03-16 10:48:52 +0000155- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox

Matthias Klose358e7ff2010-03-15 13:42:23 +0000160- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
161 the locale.
162
Georg Brandlba83f822010-03-14 09:50:54 +0000163- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000164 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000165 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000166
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000167- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000168 for ``TimedRotatingFileHandler`` by using the modification time of an
169 existing log file to compute the next rollover time. If the log file does
170 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000171
Georg Brandlba83f822010-03-14 09:50:54 +0000172- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

179
Georg Brandlba83f822010-03-14 09:50:54 +0000180- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
181 a base64 transfer-encoded payload *after* decoding it; it no longer does.
182 This is a behavior change, so email's minor version number is now bumped, to
183 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000184
Larry Hastings3b958e32010-04-02 11:18:17 +0000185- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is

198
Martin v. Löwis16ea5482010-04-07 11:01:46 +0000199- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
200
Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000201- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
202
Jesus Cea6557aac2010-03-22 14:22:26 +0000203- Issue #8156: bsddb module updated to version 4.8.4.
204 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
205 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000206
Matthias Klose817acef2010-03-15 00:02:36 +0000207- Issue #8142: Update libffi to the 3.0.9 release.
208
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000209- Issue #8300: When passing a non-integer argument to struct.pack with any
210 integer format code, struct.pack first attempts to convert the non-integer
211 using its __index__ method. If that method is non-existent or raises
212 TypeError it goes on to try the __int__ method, as described below.
213
Georg Brandlba83f822010-03-14 09:50:54 +0000214- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
215 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
216 argument's __int__ method to convert to an integer before packing. It also
217 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
218 was inconsistent: __int__ was used for some integer codes but not for others,
219 and the set of integer codes for which it was used differed between native
220 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000221
Brian Curtin19479fa2010-04-02 21:51:37 +0000222- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a

257
Larry Hastings402b73f2010-03-25 00:54:54 +0000258- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported

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

Georg Brandlba83f822010-03-14 09:50:54 +0000530- Issue #7748: Since unicode values are supported for some metadata options in
531 Distutils, the DistributionMetadata get_* methods will now return an utf-8
532 encoded string for them. This ensures that the upload and register commands
533 send the correct values to PyPI without any error.

607Core and Builtins
608-----------------
609
Georg Brandlba83f822010-03-14 09:50:54 +0000610- The ``__complex__()`` method is now looked up on the class of instances to
611 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000613- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
614 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
615
Mark Dickinson1b34d252010-01-01 17:27:30 +0000616- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000617 DeprecationWarning when passed a float argument where an integer was expected.
618 These functions and methods now raise TypeError instead. The majority of the
619 effects of this change are in the extension modules, but some core functions
620 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
621 and many unicode/str methods.

633
Georg Brandlba83f822010-03-14 09:50:54 +0000634- Issue #1811: Improve accuracy and cross-platform consistency for true division
635 of integers: the result of a/b is now correctly rounded for ints a and b (at
636 least on IEEE 754 platforms), and in particular does not depend on the
637 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +0000639- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +0000644 executables on OSX.
645
Georg Brandlba83f822010-03-14 09:50:54 +0000646 These executables now work properly with the arch(1) command: ``arch -ppc
647 python`` will start a universal binary version of python in PPC mode (unlike
648 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000650- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

Georg Brandlba83f822010-03-14 09:50:54 +0000783- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
784 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000785
Georg Brandlba83f822010-03-14 09:50:54 +0000786- Issue #3382: 'F' formatting for float and complex now convert the result to
787 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
788 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000789
Georg Brandlba83f822010-03-14 09:50:54 +0000790- Remove switch from "%f" formatting to "%g" formatting for floats larger than
791 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000792
Georg Brandlba83f822010-03-14 09:50:54 +0000793- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
794 1e-100 used to raise OverflowError, but now gives the requested 120
795 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000796
Georg Brandlba83f822010-03-14 09:50:54 +0000797- Add Py3k warnings for parameter names in parentheses.

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000800
Georg Brandlba83f822010-03-14 09:50:54 +0000801- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
802 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000803
Georg Brandlba83f822010-03-14 09:50:54 +0000804- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
805 decimal string that's guaranteed to round back to x under correct rounding
806 (with round-half-to-even rounding mode). Previously it gave a string based on
807 rounding x to 17 decimal digits. repr(x) for a complex number behaves
808 similarly. On platforms where the correctly-rounded strtod and dtoa code is
809 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000810
Georg Brandlba83f822010-03-14 09:50:54 +0000811- Issue #7117: On almost all platforms: float-to-string and string-to-float
812 conversions within Python are now correctly rounded. Places these conversions
813 occur include: str for floats and complex numbers; the float and complex
814 constructors; old-style and new-style numeric formatting; serialization and
815 deserialization of floats and complex numbers using marshal, pickle and json;
816 parsing of float and imaginary literals in Python code; Decimal-to-float
817 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000818
Georg Brandlba83f822010-03-14 09:50:54 +0000819 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
820 providing correctly-rounded strtod and dtoa C functions. This code is
821 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
822 the C compiler. There may be a small number of platforms on which correct
823 operation of this code cannot be guaranteed, so the code is not used: notably,
824 this applies to platforms where the C double format is not IEEE 754 binary64,
825 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
826 and Python's configure script is unable to determine how to change the FPU
827 precision. On these platforms conversions use the platform strtod and dtoa,
828 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000829
Georg Brandlba83f822010-03-14 09:50:54 +0000830- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
831 uses the correctly-rounded string <-> float conversions described above (when
832 available), and so produces correctly rounded results that will display nicely
833 under the float repr. There are two related small changes: (1) round now
834 accepts any class with an ``__index__()`` method for its second argument (but
835 no longer accepts floats for the second argument), and (2) an excessively
836 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
837 raises an exception.

840
Georg Brandlba83f822010-03-14 09:50:54 +0000841- Fix several issues with ``compile()``. The input can now contain Windows and
842 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +0000843

Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000872- Issue #1571184: The Unicode database contains properties for more characters.
873 The tables for code points representing numeric values, white spaces or line
874 breaks are now generated from the official Unicode Character Database files,
875 and include information from the Unihan.txt file.

987 of 12. Previously, the behavior the same but with a default precision of 6.
988 This more closely matches ``str()``, and reduces surprises when adding

Walter Dörwalded960ac2009-05-03 22:36:33 +00001242- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1243 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

1252 gives improved memory leak detection when running under Valgrind, while taking
1253 advantage of pymalloc at other times.

2622 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

Antoine Pitrou0668c622008-08-26 22:42:08 +00002646 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2647 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2648 when given a tuple of classes as second argument, were looking up
2649 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2650 type object.

2790================================
2791
Barry Warsaw07a4a382008-08-21 01:15:08 +00002792*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002793
2794Core and Builtins
2795-----------------
2796
Guido van Rossumf8402962008-08-20 15:01:50 +00002797- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2798 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2799 extensions do not automatically benefit from the class attribute
2800 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2801 to their tp_flags field if they care. This is a backwards
2802 compatibility feature; in 3.0, all types will use the cache by
2803 default.
2804
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002805- Keyword arguments can now follow starred arguments. (``f(a, *args,
2806 keyword=23)`` is now valid syntax.)
2807
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002808- ctypes function pointers that are COM methods have a boolean True
2809 value again.
2810
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002811- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2812 by denying s# to parse objects that have a releasebuffer procedure,
2813 and introducing s*.
2814
Georg Brandl1e13ea92008-08-11 09:07:59 +00002815- Issue #3537: Fix an assertion failure when an empty but presized dict
2816 object was stored in the freelist.
2817
Mark Dickinsonb6467572008-08-04 21:30:09 +00002818- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2819 ValueError consistently across platforms.
2820
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002821- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2822 (64bit Unix, for example), unichr() would truncate its argument and return
2823 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2824
Neal Norwitze7d8be82008-07-31 17:17:14 +00002825- Apply security patches from Apple.
2826
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002827- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2828 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2829
Antoine Pitrou92f82162008-07-25 22:22:08 +00002830- Issue #1819: function calls with several named parameters are now on
2831 average 35% faster (as measured by pybench).
2832
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002833- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2834 the python debugger steps into a class statement: the free variables (local
2835 variables defined in an outer scope) would be deleted from the outer scope.
2836
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002837- Issue #2620: Overflow checking when allocating or reallocating memory
2838 was not always being done properly in some python types and extension
2839 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2840 all been updated to perform better checks and places in the code that
2841 would previously leak memory on the error path when such an allocation
2842 failed have been fixed.

2846
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002847- Issue #3612: Added some missing basic types in ctypes.wintypes.
2848
Benjamin Petersone977ad42008-08-20 01:42:01 +00002849- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2850 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2851
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002852- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2853 version reported by these tools does not necessarily follow the python
2854 version numbering scheme, so the module is less strict when parsing it.
2855
Nick Coghlanf70385a2008-08-18 12:42:46 +00002856- Issue #2235: Added Py3k warnings for types which will become unhashable
2857 under the stricter __hash__ inheritance rules in 3.0. Several types
2858 which did not meet the rules for hash invariants and were already
2859 unhashable in 3.0 have now been explicitly flagged as unhashable in
2860 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2861 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2862
Brett Cannon88f801d2008-08-18 00:46:22 +00002863- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2864 imported into the module but exposed as part of the module's API.
2865
Brett Cannon7b96f072008-08-18 00:41:11 +00002866- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2867
Brett Cannon46225e72008-08-18 00:36:52 +00002868- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002870- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2871
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002872- Issue #3575: Incremental decoder's decode function now takes bytearray
2873 by using 's*' instead of 't#'.
2874
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002875- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002876 fails unicode conversion on 2nd parameter. (windows only)
2877
Facundo Batista94f243a2008-08-17 03:38:39 +00002878- Issue 2464. urllib2 now supports a malformation in the URL received
2879 in a redirect.
2880
Brett Cannonabe423e2008-08-16 21:47:07 +00002881- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002882 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002883
Facundo Batistaeb90b782008-08-16 14:44:07 +00002884- Issue #2776: fixed small issue when handling an URL with double slash
2885 after a 302 response in the case of not going through a proxy.
2886
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002887- Issue #2676: in the email package, content-type parsing was hanging on
2888 pathological input because of quadratic or exponential behaviour of a
2889 regular expression.
2890
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002891- Issue #3476: binary buffered reading through the new "io" library is now
2892 thread-safe.
2893
Brett Cannonbf3157b2008-08-14 05:00:03 +00002894- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2895 since mimetools itself is deprecated. Because modules are cached, all
2896 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2897
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002898- Issue #3134: shutil referenced undefined WindowsError symbol.
2899
Robert Schuppenies14646332008-08-10 11:01:53 +00002900- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2901 menu entries were not deleted.
2902
Brett Cannon83e81842008-08-09 23:30:55 +00002903- Copied the implementation of reduce() to _functools.reduce() to have a
2904 version that did not raise a DeprecationWarning under -3.
2905
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002906- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2907 a MemoryError rather than silently stop the iteration.
2908
Guido van Rossum59ce9012008-08-09 14:55:34 +00002909- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2910 to _sre.compile() will now be rejected. This should not affect anybody
2911 since the re.compile() function never generates invalid re-bytecode.
2912
Skip Montanaroa032bf42008-08-08 22:52:51 +00002913- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2914 upon first access it can be automatically initialized from the csv file if
2915 it wasn't initialized during instantiation.
2916
Brett Cannon3aa2a492008-08-06 22:28:09 +00002917- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2918 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00002932 asking for a specific length. This problem only affected files opened
2933 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002934

2959 file name rather than a ZipInfo instance, so files are extracted with
2960 mode 0600 rather than 000 under Unix.
2961
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002962- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2989-----------------
2990
Georg Brandl3e483f62008-07-16 22:57:41 +00002991- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2992 its methods now allow for items objects that can be converted to
2993 an integer using operator.index().
2994
Mark Dickinson64b7e502008-07-16 09:40:03 +00002995- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2996 produced a ValueError instead of giving the correct float.
2997
Eric Smitha5fa5a22008-07-16 00:11:49 +00002998- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2999 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3000
Mark Dickinson7103aa42008-07-15 19:08:33 +00003001- Issue #3008: the float type has a new instance method 'float.hex'
3002 and a new class method 'float.fromhex' to convert floating-point
3003 numbers to and from hexadecimal strings, respectively.
3004
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003005- Issue #2235: __hash__ is once again inherited by default. To allow
3006 collections.Hashable to remain meaningful in the presence of the
3007 default hash implementation (object.__hash__), it is now possible
3008 to explicit block inheritance of hash by setting __hash__=None at
3009 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3010 level.
3011
Nick Coghlanb028f502008-07-13 14:52:36 +00003012- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3013 the parent module cannot be found while performing an absolute import.
3014 This means that an incorrectly defined __package__ attribute will
3015 now only prevent relative imports in that module rather than causing
3016 all imports from that module to fail.
3017
Nick Coghlan14ff9942008-07-08 14:21:42 +00003018- Issue #2517: Allow unicode messages in Exceptions again by correctly

3027 threading.local: the first member set by a thread could be saved in
3028 another thread's dictionary.
3029
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003030- Issue #3004: Minor change to slice.indices(): the start and stop
3031 arguments are now treated identically, making the behaviour easier
3032 to describe and understand. For example, slice(None, -10,
3033 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3034 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3035 10, -1).
3036
Georg Brandl278fc502008-07-19 12:46:12 +00003037- Issue #3219: Calling a function with repeated keyword arguments,
3038 f(a=2, a=23), would not cause a syntax error. This was a regression
3039 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003040
Georg Brandl278fc502008-07-19 12:46:12 +00003041- Issue #2862: Make int and float freelist management consistent with
3042 other freelists. Changes their CompactFreeList apis into

3049 api functions without holding the GIL, which could lead to a fatal
3050 error when they failed.
3051
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003052- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003077- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3078 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003079 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003080 content-length. The problem had been corrected in the 2.4 branch, but never
3081 merged into trunk.
3082
Georg Brandle78fbcc2008-07-05 10:13:36 +00003083- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003096- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3097 handling is now the same as that of other special attributes like __name__).
3098
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003099- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003487- On MacOS X it is now possible to install the framework in 64-bit
3488 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003489 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003490
3491 This is controlled by the configure argument ``--with-universal-archs``:
3492
3493 - ``--with-universal-archs=all``: install 4-way universal
3494
3495 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3496
3497 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3498
3499 This option should be used in combination with ``--enable-universalsdk=``.
3500
3501 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3506
Georg Brandl74a1dea2008-05-28 11:21:39 +00003507- Add ``PyType_Modified()`` as a public API to clear the type cache.
3508
3509- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003510
3511- The PyString functions have been renamed to PyBytes. A batch of
3512 defines were added so that the linker still sees the original
3513 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003551- Issue #1631171: Re-implement the 'warnings' module in C (the
3552 original Python code has been kept as backup). This will allow for
3553 using the 'warning's machinery in such places as the parser where
3554 use of pure Python code is not possible. Both the ``showarning()``
3555 and ``formatwarning()`` gain an optional 'line' argument which is
3556 not called by default for backwards-compatibility reasons. Setting
3557 ``warnings.showwarning()`` to an implementation that lacks support
3558 for the ``line`` argument will raise a DeprecationWarning.

3582
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003583- The getpass module has been improved on Unix. It now uses /dev/tty
3584 by default and uses stderr instead of stdout. A GetPassWarning is
3585 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003600- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003601 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003621- Issue #2550: The approach used by client/server code for obtaining
3622 ports to listen on in network-oriented tests has been refined in an
3623 effort to facilitate running multiple instances of the entire
3624 regression test suite in parallel without issue.
3625 test_support.bind_port() has been fixed such that it will always
3626 return a unique port -- which wasn't always the case with the
3627 previous implementation, especially if socket options had been set
3628 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3629 new implementation of bind_port() will actually raise an exception
3630 if it is passed an AF_INET/SOCK_STREAM socket with either the
3631 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3632 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3633 the socket it's been passed. This currently only applies to
3634 Windows. This option prevents any other sockets from binding to the
3635 host/port we've bound to, thus removing the possibility of the
3636 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3637 when a second SOCK_STREAM socket binds and accepts to a host/port
3638 that's already been bound by another socket. The optional preferred
3639 port parameter to bind_port() has been removed. Under no
3640 circumstances should tests be hard coding ports!
3641
3642 test_support.find_unused_port() has also been introduced, which will
3643 pass a temporary socket object to bind_port() in order to obtain an
3644 unused port. The temporary socket object is then closed and
3645 deleted, and the port is returned. This method should only be used
3646 for obtaining an unused port in order to pass to an external program
3647 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3648 a parameter to a server-oriented class that doesn't give you direct
3649 access to the underlying socket used.
3650
3651 Finally, test_support.HOST has been introduced, which should be used
3652 for the host argument of any relevant socket calls (i.e. bind and
3653 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003654
3655 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003656 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003657 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3658 test_asynchat and test_socket_ssl.
3659
Georg Brandl3ee81df2008-05-17 18:14:43 +00003660 It is now possible for multiple instances of the regression test
3661 suite to run in parallel without issue.

3928-----------------
3929
Fred Drakea8ee94b2008-03-01 02:45:07 +00003930- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003931 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003936
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003937- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003938 issue 215555 for a discussion.
3939
Eric Smitha73fbe72008-02-23 03:09:44 +00003940- Added the future_builtins module, which contains hex() and oct().
3941 These are the PEP 3127 version of these functions, designed to be
3942 compatible with the hex() and oct() builtins from Python 3.0. They
3943 differ slightly in their output formats from the existing, unchanged
3944 Python 2.6 builtins. The expected usage of the future_builtins
3945 module is:
3946 from future_builtins import hex, oct
3947
Eric Smith7ef40bf2008-02-20 23:34:22 +00003948- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3949 exponents for exponents with absolute value < 100. Follows C99
3950 standard. This is a change on Windows, which would use 3 digits.
3951 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3952 so that any alterations it does to the resulting string will be
3953 available in stringlib/formatter.h (for float.__format__).
3954
Eric Smith5a3c1352008-02-19 13:21:56 +00003955- Implemented PEP 3101, Advanced String Formatting. This adds a new
3956 builtin format(); a format() method for str and unicode; a
3957 __format__() method to object, str, unicode, int, long, float, and
3958 datetime; the class string.Formatter; and the C API
3959 PyObject_Format().
3960
Georg Brandl3ee81df2008-05-17 18:14:43 +00003961- Fixed several potential crashes, all caused by specially crafted
3962 __del__ methods exploiting objects in temporarily inconsistent
3963 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003964
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003965- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003966 prevent a possible crash: an Abstract Base Class would try to access
3967 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003972- Clear all free lists during a gc.collect() of the highest generation
3973 in order to allow pymalloc to free more arenas. Python may give back
3974 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003975
Georg Brandl3ee81df2008-05-17 18:14:43 +00003976- Issue #2045: Fix an infinite recursion triggered when printing a
3977 subclass of collections.defaultdict, if its default_factory is set
3978 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003979
Christian Heimesf75dbef2008-02-08 00:11:31 +00003980- Fixed a minor memory leak in dictobject.c. The content of the free
3981 list was not freed on interpreter shutdown.
3982
Georg Brandl21e99f42010-03-07 15:23:59 +00003983- Limit free list of method and built-in function objects to 256

3987 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003988 to compact the internal free lists of pre-allocted ints and floats.
3989
Georg Brandl3ee81df2008-05-17 18:14:43 +00003990- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3991 calls. Python expected the return type int but the fork familie
3992 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003993

4004 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004005
Georg Brandl3ee81df2008-05-17 18:14:43 +00004006- Patch #1473257: generator objects gain a gi_code attribute. This is
4007 the same object as the func_code attribute of the function that
4008 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004009
Georg Brandl3ee81df2008-05-17 18:14:43 +00004010- Issue #1920: "while 0" statements were completely removed by the
4011 compiler, even in the presence of an "else" clause, which is
4012 supposed to be run when the condition is false. Now the compiler
4013 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004014
Guido van Rossumeead05f2008-01-24 18:21:02 +00004015- A few crashers fixed: weakref_in_del.py (issue #1377858);
4016 loosing_dict_ref.py (issue #1303614, test67.py);
4017 borrowed_ref_[34].py (not in tracker).
4018
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004019- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004020 suppressed while an extension is loaded by calling SetErrorMode in
4021 dynload_win.c. The error is still reported properly.
4022
Georg Brandl3ee81df2008-05-17 18:14:43 +00004023- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004024 several extension methods and modules do not work without unicode
4025 support.
4026
Georg Brandl26543b12008-01-21 18:36:51 +00004027- Issue #1882: when compiling code from a string, encoding cookies in the
4028 second line of code were not always recognized correctly.
4029
Georg Brandl14404b62008-01-19 19:27:05 +00004030- Issue #1679: "0x" was taken as a valid integer literal.
4031
Georg Brandl6caad7d2008-01-26 14:19:22 +00004032- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004033 added.
4034
Christian Heimesc94e2b52008-01-14 04:13:37 +00004035- sys.float_info / PyFloat_GetInfo: The floating point information
4036 object was converted from a dict to a specialized structseq object.
4037
Georg Brandl3ee81df2008-05-17 18:14:43 +00004038- Patch #1816: Added sys.flags structseq. It exposes the status of
4039 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004040
Georg Brandl3ee81df2008-05-17 18:14:43 +00004041- Objects/structseq.c: Implemented new structseq representation. The
4042 patch makes structseqs (e.g. the return value of os.stat) more
4043 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004044
Georg Brandl3ee81df2008-05-17 18:14:43 +00004045- Patch #1700288: added a type attribute cache that caches method
4046 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004047
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004048- Bug #1776: __import__() no longer accepts filenames on any platform.
4049 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004050
Georg Brandlaed6c662008-01-07 17:25:53 +00004051- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4052
Georg Brandl3ee81df2008-05-17 18:14:43 +00004053- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4054 envvar and sys.dont_write_bytecode attribute. All these can be set
4055 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004056
Georg Brandl3ee81df2008-05-17 18:14:43 +00004057- Improve some exception messages when Windows fails to load an
4058 extension module. Now we get for example '%1 is not a valid Win32
4059 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004060
Georg Brandl3ee81df2008-05-17 18:14:43 +00004061- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004063- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4064 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004065
Christian Heimes0a8143f2007-12-18 23:22:54 +00004066- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004067 and INF. float("nan"), float("inf") and float("-inf") now work on
4068 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004069
Georg Brandl3ee81df2008-05-17 18:14:43 +00004070- Compiler now generates simpler and faster code for dictionary
4071 literals. The oparg for BUILD_MAP now indicates an estimated
4072 dictionary size. There is a new opcode, STORE_MAP, for adding
4073 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004074
Georg Brandl3ee81df2008-05-17 18:14:43 +00004075- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004077- Issue #1620: New property decorator syntax was modifying the
4078 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004079
Georg Brandl3ee81df2008-05-17 18:14:43 +00004080- Issue #1538: Avoid copying string in split/rsplit if the split char
4081 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004082
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004083- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004084 SystemError.
4085
Nick Coghlanef01d822007-12-03 12:55:17 +00004086- PEP 366: Allow explicit relative imports when executing modules
4087 inside packages with the -m switch via a new module level
4088 __package__ attribute.
4089
Georg Brandl3ee81df2008-05-17 18:14:43 +00004090- Issue #1402: Fix a crash on exit, when another thread is still
4091 running, and if the deallocation of its frames somehow calls the
4092 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004093

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004097 attribute of an empty cell object.
4098
Georg Brandl3ee81df2008-05-17 18:14:43 +00004099- Issue #1460: The utf-7 incremental decoder did not accept truncated
4100 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004101
Georg Brandl3ee81df2008-05-17 18:14:43 +00004102- Patch #1739468: Directories and zipfiles containing a __main__.py
4103 file can now be directly executed by passing their name to the
4104 interpreter. The directory/zipfile is automatically inserted as the
4105 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004106
Georg Brandl3ee81df2008-05-17 18:14:43 +00004107- Issue #1265: Fix a problem with sys.settrace, if the tracing
4108 function uses a generator expression when at the same time the
4109 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004110
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004111- sets and frozensets now have an isdisjoint() method.
4112
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004113- optimize the performance of builtin.sum().
4114
Neal Norwitz44f326e2007-10-05 05:29:17 +00004115- Fix warnings found by the new version of the Coverity checker.
4116
Georg Brandl21e99f42010-03-07 15:23:59 +00004117- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4119 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004120
Georg Brandl3ee81df2008-05-17 18:14:43 +00004121- Issue #1686386: Tuple's tp_repr did not take into account the
4122 possibility of having a self-referential tuple, which is possible
4123 from C code. Nor did object's tp_str consider that a type's tp_str
4124 could do something that could lead to an inifinite recursion.
4125 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4126 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004127
Georg Brandl3ee81df2008-05-17 18:14:43 +00004128- Issue #1164: It was possible to trigger deadlock when using the
4129 'print' statement to write to a file since the GIL was not released
4130 as needed. Now PyObject_Print() does the right thing along with
4131 various tp_print implementations of the built-in types and those in
4132 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004133
Georg Brandl3ee81df2008-05-17 18:14:43 +00004134- Issue #1147: Exceptions were directly allowing string exceptions in
4135 their throw() method even though string exceptions no longer
4136 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004137
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138- Issue #1096: Prevent a segfault from getting the repr of a very
4139 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004140
Brett Cannon1e534b52007-09-07 04:18:30 +00004141- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142 PyObject_Call() never calling back out to Python code to trigger
4143 recursion depth updates/checks. Required the creation of a static
4144 RuntimeError instance in case normalizing an exception put the
4145 recursion check value past its limit. Fixes crashers
4146 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004147
Georg Brandl3ee81df2008-05-17 18:14:43 +00004148- Patch #1031213: Decode source line in SyntaxErrors back to its

4152 with %G.
4153
Georg Brandl3ee81df2008-05-17 18:14:43 +00004154- Prevent expandtabs() on string and unicode objects from causing a
4155 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00004156

Neal Norwitz0ac60192007-05-27 04:08:54 +00004161- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004162 __*__ attributes. (Some already existed, e.g., __doc__ and
4163 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004164
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004165- Add -3 option to the interpreter to warn about features that are
4166 deprecated and will be changed/removed in Python 3.0.
4167
Georg Brandl2134e752007-05-21 20:34:16 +00004168- Patch #1686487: you can now pass any mapping after '**' in function
4169 calls.
4170
Collin Winter62903052007-05-18 23:11:24 +00004171- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172 "except E as target:". This is to provide forwards compatibility
4173 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004174
Brett Cannon229cee22007-05-05 01:34:02 +00004175- Deprecate BaseException.message as per PEP 352.
4176
Georg Brandl3ee81df2008-05-17 18:14:43 +00004177- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004178 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004179
Vinay Sajip8549ce32007-05-06 17:53:37 +00004180- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004181 setting a plain string, ie don't expand to single letter identifiers.
4182
Raymond Hettinger13936692007-04-11 18:40:58 +00004183- Request #1191699: Slices can now be pickled.
4184
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004185- Request #1193128: str.translate() now allows a None argument for
4186 translations that only remove characters without re-mapping the
4187 remaining characters.
4188
Georg Brandl5cb76c12007-03-21 09:00:39 +00004189- Patch #1682205: a TypeError while unpacking an iterable is no longer
4190 masked by a generic one with the message "unpack non-sequence".
4191
Neal Norwitzaa754b72007-03-21 06:39:48 +00004192- Remove unused file Python/fmod.c.
4193
Guido van Rossum143b5642007-03-23 04:58:42 +00004194- Bug #1683368: The object.__init__() and object.__new__() methods are
4195 now stricter in rejecting excess arguments. The only time when
4196 either allows excess arguments is when it is not overridden and the
4197 other one is. For backwards compatibility, when both are
4198 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004199 warning later). Also, type.__init__() insists on the same signature
4200 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004201
Georg Brandl3ee81df2008-05-17 18:14:43 +00004202- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4203 object to complex using its __complex__() method before falling back
4204 to the __float__() method. Therefore, the functions in the cmath
4205 module now can operate on objects that define a __complex__()
4206 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004207
Georg Brandl3ee81df2008-05-17 18:14:43 +00004208- Patch #1623563: allow __class__ assignment for classes with
4209 __slots__. The old and the new class are still required to have the
4210 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004211
Georg Brandl3ee81df2008-05-17 18:14:43 +00004212- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004215- Patch #1462488: Python no longer segfaults when
4216 ``object.__reduce_ex__()`` is called with an object that is faking
4217 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004218
Georg Brandl3ee81df2008-05-17 18:14:43 +00004219- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00004222- Patch #1444529: the builtin compile() now accepts keyword arguments.
4223
Georg Brandl7b9c5552007-03-12 14:30:05 +00004224- Bug #1678647: write a newline after printing an exception in any
4225 case, even when converting the value to a string failed.
4226
Georg Brandl871f1bc2007-03-12 13:17:36 +00004227- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004228 its argument, if it exists. If not, it will work like before. This
4229 allows customizing the output of dir() in the presence of a
4230 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004231
Collin Winter276887b2007-03-12 16:11:39 +00004232- Patch #922167: Python no longer segfaults when faced with infinitely
4233 self-recursive reload() calls (as reported by bug #742342).
4234
Georg Brandl3ee81df2008-05-17 18:14:43 +00004235- Patch #1675981: remove unreachable code from ``type.__new__()``
4236 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004238- Patch #1491866: change the complex() constructor to allow
4239 parthensized forms. This means complex(repr(x)) now works instead of
4240 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004241

4751 ".cpp" too.
4752
Facundo Batistad918a652007-04-24 13:54:38 +00004753- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004754 the client's request was successfully received, understood, and
4755 accepted. Now in these cases no error is raised in urllib (issue
4756 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004757

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004764- Added a timeout parameter to the constructor of other protocols
4765 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4766 work started with create_connection() and timeout in httplib, and
4767 closes patch #723312.
4768
Vinay Sajip8549ce32007-05-06 17:53:37 +00004769- Patch #1676823: Added create_connection() to socket.py, which may be
4770 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004771 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004772
Martin v. Löwis0af33882007-03-23 13:27:15 +00004773- Bug #978833: Revert r50844, as it broke _socketobject.dup.

4793
Georg Brandlf66b6032007-03-14 08:27:52 +00004794- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004795 AttributeError instead of an IOError when the server's response
4796 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004797
Georg Brandl3ee81df2008-05-17 18:14:43 +00004798- Patch #957650: "%var%" environment variable references are now
4799 properly expanded in ntpath.expandvars(), also "~user" home
4800 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00004801
Georg Brandl3ee81df2008-05-17 18:14:43 +00004802- Patch #1429539: pdb now correctly initializes the __main__ module
4803 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004804 correctly now.
4805
Georg Brandlbad6f192007-03-13 21:32:56 +00004806- The nonobvious commands.getstatus() function is now deprecated.

4812
Georg Brandl3ee81df2008-05-17 18:14:43 +00004813- Patch #1530482: add pydoc.render_doc() which returns the
4814 documentation for a thing instead of paging it to stdout, which
4815 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004816
Georg Brandl3ee81df2008-05-17 18:14:43 +00004817- Patch #1533909: the timeit module now accepts callables in addition

4823 parameter which can be set to False to prevent the default
4824 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00004826- Patch #1581073: add a flag to textwrap that prevents the dropping of
4827 whitespace while wrapping.
4828
Georg Brandl92a6bae2007-03-13 17:43:32 +00004829- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004830 are set for invalid interpolation sequences that would lead to
4831 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004832

4845
Georg Brandl94fe3f52007-03-13 09:32:11 +00004846- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00004847 field names in its exception message if you try to write a record
4848 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004866

4874 returned string up to the first NUL character.

4885
Georg Brandl3ee81df2008-05-17 18:14:43 +00004886- unittest now verifies more of its assumptions. In particular,
4887 TestCase and TestSuite subclasses (not instances) are no longer
4888 accepted in TestSuite.addTest(). This should cause no
4889 incompatibility since it never made sense with ordinary subclasses
4890 -- the failure just occurred later, with a more cumbersome
4891 exception.

4901
Georg Brandl3ee81df2008-05-17 18:14:43 +00004902- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00005280 time so that opening a database previously created with the DB_DUP
5281 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5282 opens. Specifically: dictionary assignment to a DB object will
5283 replace all values for a given key when the database allows
5284 duplicate values. DB users should use DB.put(k, v) when they want
5285 to store duplicates; not DB[k] = v.

5292 characters with ASCII value less than 32. Also, it correctly quotes
5293 dots only if they occur on a single line, as opposed to the previous
5294 behavior of quoting dots if they are the second character of any
5295 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005296
