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.

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.

64
Martin v. Löwis1b287c72010-04-08 09:47:40 +000065- Issue #8344: Fix test_ttk bug on FreeBSD.
66
Antoine Pitrouf9de5342010-04-05 21:35:07 +000067- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
68 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`

72
Mark Dickinson8a950712010-04-03 15:47:46 +000073- Issue #8257: The Decimal construct now accepts a float instance
74 directly, converting that float to a Decimal of equal value:
75
76 >>> Decimal(1.1)
77 Decimal('1.100000000000000088817841970012523233890533447265625')
78
Raymond Hettinger34c35b22010-04-03 10:22:00 +000079- collections.Counter() now supports a subtract() method.
80
Raymond Hettingera551f312010-04-04 18:34:45 +000081- the functools module now has a total_ordering() class decorator
82 to simplify the specifying rich comparisons.
83
Raymond Hettingerbb006cf2010-04-04 21:45:01 +000084- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +000085 old-style comparison functions to new-style key-functions.
86
Mark Dickinson7c63eee2010-04-02 22:27:36 +000087- Issue #8294: The Fraction constructor now accepts Decimal and float
88 instances directly.
89
Mark Dickinsone096e822010-04-02 10:17:07 +000090- Issue #7279: Comparisons involving a Decimal signaling NaN now
91 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000092 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
93 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000094
Mark Dickinson99d80962010-04-02 08:53:22 +000095- Issue #2531: Comparison operations between floats and Decimal
96 instances now return a result based on the numeric values of the
97 operands; previously they returned an arbitrary result based on
98 the relative ordering of id(float) and id(Decimal).
99
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000100- Issue #8233: When run as a script, py_compile.py optionally takes a single
101 argument `-` which tells it to read files to compile from stdin. Each line
102 is read on demand and the named file is compiled immediately. (Original
103 patch by Piotr Ożarowski).
104
105- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
106 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000107
Florent Xicluna58b65662010-03-30 16:29:03 +0000108- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
109 form feed (0x0C) are now considered linebreaks, as specified in Unicode
110 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000111 http://www.unicode.org/reports/tr14/
112
Mark Dickinson9588d992010-03-27 11:14:37 +0000113- Comparisons using one of <, <=, >, >= between a complex instance and
114 a Fractions instance now raise TypeError instead of returning
115 True/False. This makes Fraction <=> complex comparisons consistent with
116 int <=> complex, float <=> complex, and complex <=> complex comparisons.
117
Michael Foorde6410c52010-03-29 20:04:23 +0000118- Addition of ``WeakSet`` to the ``weakref`` module.
119

121
Florent Xicluna176cda12010-03-22 22:52:11 +0000122- Issue #8205: Remove the "Modules" directory from sys.path when Python is
123 running from the build directory (POSIX only).
124
Florent Xiclunae1f4c922010-03-22 22:45:50 +0000125- Issue #7667: Fix doctest failures with non-ASCII paths.
126
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000127- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
128 didn't support chflags() (for example ZFS under FreeBSD). The error is
129 now silenced.
130
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000131- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
132 deprecated.
133
R. David Murrayc9d1a782010-03-22 15:55:09 +0000134- Issue #7860: platform.uname now reports the correct 'machine' type
135 when Python is running in WOW64 mode on 64 bit Windows.
136
Vinay Sajip804899b2010-03-22 15:29:01 +0000137- logging: Added getChild utility method to Logger and added isEnabledFor
138 method to LoggerAdapter.
139
Vinay Sajip31e928e2010-03-22 13:02:28 +0000140- Issue #8201: logging: Handle situation of non-ASCII and Unicode
141 logger names existing at the same time, causing a Unicode error
142 when configuration code attempted to sort the existing loggers.
143
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000144- Issue #8200: logging: Handle errors when multiprocessing is not
145 fully loaded when logging occurs.
146
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000147- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
148 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
149 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000150
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000151- Issue #8179: Fix macpath.realpath() on a non-existing path.

165 the locale.
166
Georg Brandlba83f822010-03-14 09:50:54 +0000167- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000168 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000169 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000170
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000171- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000172 for ``TimedRotatingFileHandler`` by using the modification time of an
173 existing log file to compute the next rollover time. If the log file does
174 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000175
Georg Brandlba83f822010-03-14 09:50:54 +0000176- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

183
Georg Brandlba83f822010-03-14 09:50:54 +0000184- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
185 a base64 transfer-encoded payload *after* decoding it; it no longer does.
186 This is a behavior change, so email's minor version number is now bumped, to
187 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000188

208 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
209 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000210
Matthias Klose817acef2010-03-15 00:02:36 +0000211- Issue #8142: Update libffi to the 3.0.9 release.
212
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000213- Issue #8300: When passing a non-integer argument to struct.pack with any
214 integer format code, struct.pack first attempts to convert the non-integer
215 using its __index__ method. If that method is non-existent or raises
216 TypeError it goes on to try the __int__ method, as described below.
217
Georg Brandlba83f822010-03-14 09:50:54 +0000218- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
219 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
220 argument's __int__ method to convert to an integer before packing. It also
221 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
222 was inconsistent: __int__ was used for some integer codes but not for others,
223 and the set of integer codes for which it was used differed between native
224 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000225
Brian Curtin19479fa2010-04-02 21:51:37 +0000226- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a

261
Larry Hastings402b73f2010-03-25 00:54:54 +0000262- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported

521 implementation is significantly faster and can be wrapped in a
522 ``io.BufferedReader`` object for more speedups. It also solves an issue
523 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Mark Dickinson1b34d252010-01-01 17:27:30 +0000620- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000621 DeprecationWarning when passed a float argument where an integer was expected.
622 These functions and methods now raise TypeError instead. The majority of the
623 effects of this change are in the extension modules, but some core functions
624 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
625 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000790- Issue #3382: 'F' formatting for float and complex now convert the result to
791 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
792 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000793
Georg Brandlba83f822010-03-14 09:50:54 +0000794- Remove switch from "%f" formatting to "%g" formatting for floats larger than
795 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000796
Georg Brandlba83f822010-03-14 09:50:54 +0000797- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
798 1e-100 used to raise OverflowError, but now gives the requested 120
799 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000800
Georg Brandlba83f822010-03-14 09:50:54 +0000801- Add Py3k warnings for parameter names in parentheses.

Georg Brandlba83f822010-03-14 09:50:54 +0000805- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
806 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000807
Georg Brandlba83f822010-03-14 09:50:54 +0000808- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
809 decimal string that's guaranteed to round back to x under correct rounding
810 (with round-half-to-even rounding mode). Previously it gave a string based on
811 rounding x to 17 decimal digits. repr(x) for a complex number behaves
812 similarly. On platforms where the correctly-rounded strtod and dtoa code is
813 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000814
Georg Brandlba83f822010-03-14 09:50:54 +0000815- Issue #7117: On almost all platforms: float-to-string and string-to-float
816 conversions within Python are now correctly rounded. Places these conversions
817 occur include: str for floats and complex numbers; the float and complex
818 constructors; old-style and new-style numeric formatting; serialization and
819 deserialization of floats and complex numbers using marshal, pickle and json;
820 parsing of float and imaginary literals in Python code; Decimal-to-float
821 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000822
Georg Brandlba83f822010-03-14 09:50:54 +0000823 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
824 providing correctly-rounded strtod and dtoa C functions. This code is
825 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
826 the C compiler. There may be a small number of platforms on which correct
827 operation of this code cannot be guaranteed, so the code is not used: notably,
828 this applies to platforms where the C double format is not IEEE 754 binary64,
829 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
830 and Python's configure script is unable to determine how to change the FPU
831 precision. On these platforms conversions use the platform strtod and dtoa,
832 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000834- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
835 uses the correctly-rounded string <-> float conversions described above (when
836 available), and so produces correctly rounded results that will display nicely
837 under the float repr. There are two related small changes: (1) round now
838 accepts any class with an ``__index__()`` method for its second argument (but
839 no longer accepts floats for the second argument), and (2) an excessively
840 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
841 raises an exception.

844
Georg Brandlba83f822010-03-14 09:50:54 +0000845- Fix several issues with ``compile()``. The input can now contain Windows and
846 Mac newlines and is no longer required to end in a newline.

Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000876- Issue #1571184: The Unicode database contains properties for more characters.
877 The tables for code points representing numeric values, white spaces or line
878 breaks are now generated from the official Unicode Character Database files,
879 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +0000988- Issue #5920: For ``float.__format__()``, change the behavior with the empty
989 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
990 but with at least one decimal point and with a default precision
991 of 12. Previously, the behavior the same but with a default precision of 6.
992 This more closely matches ``str()``, and reduces surprises when adding
993 alignment flags to the empty presentation type. This also affects the new
994 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00001134- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1135 existing .py counterpart, override the co_filename attributes of all code

Walter Dörwalded960ac2009-05-03 22:36:33 +00001246- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1247 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

1256 gives improved memory leak detection when running under Valgrind, while taking
1257 advantage of pymalloc at other times.

2636 object; previously an int would be returned for small values. the __long__
2637 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002645- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002646 PyArg_ParseTuple and friends, which occurred when the argument for "s*"

Vinay Sajip35e3b032008-09-01 14:33:59 +00002649- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002650 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2651 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2652 when given a tuple of classes as second argument, were looking up
2653 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2654 type object.

2794================================
2795
Barry Warsaw07a4a382008-08-21 01:15:08 +00002796*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002797
2798Core and Builtins
2799-----------------
2800
Guido van Rossumf8402962008-08-20 15:01:50 +00002801- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2802 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2803 extensions do not automatically benefit from the class attribute
2804 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2805 to their tp_flags field if they care. This is a backwards
2806 compatibility feature; in 3.0, all types will use the cache by
2807 default.
2808
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002809- Keyword arguments can now follow starred arguments. (``f(a, *args,
2810 keyword=23)`` is now valid syntax.)
2811
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002812- ctypes function pointers that are COM methods have a boolean True
2813 value again.
2814
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002815- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2816 by denying s# to parse objects that have a releasebuffer procedure,
2817 and introducing s*.
2818
Georg Brandl1e13ea92008-08-11 09:07:59 +00002819- Issue #3537: Fix an assertion failure when an empty but presized dict
2820 object was stored in the freelist.
2821
Mark Dickinsonb6467572008-08-04 21:30:09 +00002822- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2823 ValueError consistently across platforms.
2824
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002825- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2826 (64bit Unix, for example), unichr() would truncate its argument and return
2827 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2828
Neal Norwitze7d8be82008-07-31 17:17:14 +00002829- Apply security patches from Apple.
2830
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002831- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2832 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2833
Antoine Pitrou92f82162008-07-25 22:22:08 +00002834- Issue #1819: function calls with several named parameters are now on
2835 average 35% faster (as measured by pybench).
2836
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002837- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2838 the python debugger steps into a class statement: the free variables (local
2839 variables defined in an outer scope) would be deleted from the outer scope.
2840
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002841- Issue #2620: Overflow checking when allocating or reallocating memory
2842 was not always being done properly in some python types and extension
2843 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2844 all been updated to perform better checks and places in the code that
2845 would previously leak memory on the error path when such an allocation
2846 failed have been fixed.

2850
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002851- Issue #3612: Added some missing basic types in ctypes.wintypes.
2852
Benjamin Petersone977ad42008-08-20 01:42:01 +00002853- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2854 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2855
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002856- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2857 version reported by these tools does not necessarily follow the python
2858 version numbering scheme, so the module is less strict when parsing it.
2859
Nick Coghlanf70385a2008-08-18 12:42:46 +00002860- Issue #2235: Added Py3k warnings for types which will become unhashable
2861 under the stricter __hash__ inheritance rules in 3.0. Several types
2862 which did not meet the rules for hash invariants and were already
2863 unhashable in 3.0 have now been explicitly flagged as unhashable in
2864 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2865 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2866
Brett Cannon88f801d2008-08-18 00:46:22 +00002867- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2868 imported into the module but exposed as part of the module's API.
2869
Brett Cannon7b96f072008-08-18 00:41:11 +00002870- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2871
Brett Cannon46225e72008-08-18 00:36:52 +00002872- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2873
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002874- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2875
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002876- Issue #3575: Incremental decoder's decode function now takes bytearray
2877 by using 's*' instead of 't#'.
2878
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002879- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002880 fails unicode conversion on 2nd parameter. (windows only)
2881
Facundo Batista94f243a2008-08-17 03:38:39 +00002882- Issue 2464. urllib2 now supports a malformation in the URL received
2883 in a redirect.
2884
Brett Cannonabe423e2008-08-16 21:47:07 +00002885- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002886 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002887
Facundo Batistaeb90b782008-08-16 14:44:07 +00002888- Issue #2776: fixed small issue when handling an URL with double slash
2889 after a 302 response in the case of not going through a proxy.
2890
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002891- Issue #2676: in the email package, content-type parsing was hanging on
2892 pathological input because of quadratic or exponential behaviour of a
2893 regular expression.
2894
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002895- Issue #3476: binary buffered reading through the new "io" library is now
2896 thread-safe.
2897
Brett Cannonbf3157b2008-08-14 05:00:03 +00002898- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2899 since mimetools itself is deprecated. Because modules are cached, all
2900 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2901
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002902- Issue #3134: shutil referenced undefined WindowsError symbol.
2903
Robert Schuppenies14646332008-08-10 11:01:53 +00002904- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2905 menu entries were not deleted.
2906
Brett Cannon83e81842008-08-09 23:30:55 +00002907- Copied the implementation of reduce() to _functools.reduce() to have a
2908 version that did not raise a DeprecationWarning under -3.
2909
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002910- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2911 a MemoryError rather than silently stop the iteration.
2912
Guido van Rossum59ce9012008-08-09 14:55:34 +00002913- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2914 to _sre.compile() will now be rejected. This should not affect anybody
2915 since the re.compile() function never generates invalid re-bytecode.
2916
Skip Montanaroa032bf42008-08-08 22:52:51 +00002917- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2918 upon first access it can be automatically initialized from the csv file if
2919 it wasn't initialized during instantiation.
2920
Brett Cannon3aa2a492008-08-06 22:28:09 +00002921- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2922 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00002936 asking for a specific length. This problem only affected files opened
2937 using the new "io" module, not the built-in open() function.

2964 mode 0600 rather than 000 under Unix.
2965
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002966- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2993-----------------
2994
Georg Brandl3e483f62008-07-16 22:57:41 +00002995- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2996 its methods now allow for items objects that can be converted to
2997 an integer using operator.index().
2998
Mark Dickinson64b7e502008-07-16 09:40:03 +00002999- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3000 produced a ValueError instead of giving the correct float.
3001
Eric Smitha5fa5a22008-07-16 00:11:49 +00003002- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3003 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3004
Mark Dickinson7103aa42008-07-15 19:08:33 +00003005- Issue #3008: the float type has a new instance method 'float.hex'
3006 and a new class method 'float.fromhex' to convert floating-point
3007 numbers to and from hexadecimal strings, respectively.
3008
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003009- Issue #2235: __hash__ is once again inherited by default. To allow
3010 collections.Hashable to remain meaningful in the presence of the
3011 default hash implementation (object.__hash__), it is now possible
3012 to explicit block inheritance of hash by setting __hash__=None at
3013 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3014 level.
3015
Nick Coghlanb028f502008-07-13 14:52:36 +00003016- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3017 the parent module cannot be found while performing an absolute import.
3018 This means that an incorrectly defined __package__ attribute will
3019 now only prevent relative imports in that module rather than causing
3020 all imports from that module to fail.
3021
Nick Coghlan14ff9942008-07-08 14:21:42 +00003022- Issue #2517: Allow unicode messages in Exceptions again by correctly

3032 another thread's dictionary.
3033
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003034- Issue #3004: Minor change to slice.indices(): the start and stop
3035 arguments are now treated identically, making the behaviour easier
3036 to describe and understand. For example, slice(None, -10,
3037 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3038 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3039 10, -1).
3040
Georg Brandl278fc502008-07-19 12:46:12 +00003041- Issue #3219: Calling a function with repeated keyword arguments,
3042 f(a=2, a=23), would not cause a syntax error. This was a regression
3043 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00003045- Issue #2862: Make int and float freelist management consistent with
3046 other freelists. Changes their CompactFreeList apis into

3053 api functions without holding the GIL, which could lead to a fatal
3054 error when they failed.
3055
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003056- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003081- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3082 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003083 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003084 content-length. The problem had been corrected in the 2.4 branch, but never
3085 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003100- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3101 handling is now the same as that of other special attributes like __name__).
3102
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003103- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003491- On MacOS X it is now possible to install the framework in 64-bit
3492 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003493 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003494
3495 This is controlled by the configure argument ``--with-universal-archs``:
3496
3497 - ``--with-universal-archs=all``: install 4-way universal
3498
3499 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3500
3501 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3502
3503 This option should be used in combination with ``--enable-universalsdk=``.
3504
3505 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3510
Georg Brandl74a1dea2008-05-28 11:21:39 +00003511- Add ``PyType_Modified()`` as a public API to clear the type cache.
3512
3513- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003514
3515- The PyString functions have been renamed to PyBytes. A batch of
3516 defines were added so that the linker still sees the original
3517 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003555- Issue #1631171: Re-implement the 'warnings' module in C (the
3556 original Python code has been kept as backup). This will allow for
3557 using the 'warning's machinery in such places as the parser where
3558 use of pure Python code is not possible. Both the ``showarning()``
3559 and ``formatwarning()`` gain an optional 'line' argument which is
3560 not called by default for backwards-compatibility reasons. Setting
3561 ``warnings.showwarning()`` to an implementation that lacks support
3562 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003587- The getpass module has been improved on Unix. It now uses /dev/tty
3588 by default and uses stderr instead of stdout. A GetPassWarning is
3589 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003604- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003605 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003625- Issue #2550: The approach used by client/server code for obtaining
3626 ports to listen on in network-oriented tests has been refined in an
3627 effort to facilitate running multiple instances of the entire
3628 regression test suite in parallel without issue.
3629 test_support.bind_port() has been fixed such that it will always
3630 return a unique port -- which wasn't always the case with the
3631 previous implementation, especially if socket options had been set
3632 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3633 new implementation of bind_port() will actually raise an exception
3634 if it is passed an AF_INET/SOCK_STREAM socket with either the
3635 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3636 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3637 the socket it's been passed. This currently only applies to
3638 Windows. This option prevents any other sockets from binding to the
3639 host/port we've bound to, thus removing the possibility of the
3640 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3641 when a second SOCK_STREAM socket binds and accepts to a host/port
3642 that's already been bound by another socket. The optional preferred
3643 port parameter to bind_port() has been removed. Under no
3644 circumstances should tests be hard coding ports!
3645
3646 test_support.find_unused_port() has also been introduced, which will
3647 pass a temporary socket object to bind_port() in order to obtain an
3648 unused port. The temporary socket object is then closed and
3649 deleted, and the port is returned. This method should only be used
3650 for obtaining an unused port in order to pass to an external program
3651 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3652 a parameter to a server-oriented class that doesn't give you direct
3653 access to the underlying socket used.
3654
3655 Finally, test_support.HOST has been introduced, which should be used
3656 for the host argument of any relevant socket calls (i.e. bind and
3657 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003658
3659 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003660 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003661 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3662 test_asynchat and test_socket_ssl.
3663
Georg Brandl3ee81df2008-05-17 18:14:43 +00003664 It is now possible for multiple instances of the regression test
3665 suite to run in parallel without issue.

3932-----------------
3933
Fred Drakea8ee94b2008-03-01 02:45:07 +00003934- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003935 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003940
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003941- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003942 issue 215555 for a discussion.
3943
Eric Smitha73fbe72008-02-23 03:09:44 +00003944- Added the future_builtins module, which contains hex() and oct().
3945 These are the PEP 3127 version of these functions, designed to be
3946 compatible with the hex() and oct() builtins from Python 3.0. They
3947 differ slightly in their output formats from the existing, unchanged
3948 Python 2.6 builtins. The expected usage of the future_builtins
3949 module is:
3950 from future_builtins import hex, oct
3951
Eric Smith7ef40bf2008-02-20 23:34:22 +00003952- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3953 exponents for exponents with absolute value < 100. Follows C99
3954 standard. This is a change on Windows, which would use 3 digits.
3955 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3956 so that any alterations it does to the resulting string will be
3957 available in stringlib/formatter.h (for float.__format__).
3958
Eric Smith5a3c1352008-02-19 13:21:56 +00003959- Implemented PEP 3101, Advanced String Formatting. This adds a new
3960 builtin format(); a format() method for str and unicode; a
3961 __format__() method to object, str, unicode, int, long, float, and
3962 datetime; the class string.Formatter; and the C API
3963 PyObject_Format().
3964
Georg Brandl3ee81df2008-05-17 18:14:43 +00003965- Fixed several potential crashes, all caused by specially crafted
3966 __del__ methods exploiting objects in temporarily inconsistent
3967 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003968
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003969- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003970 prevent a possible crash: an Abstract Base Class would try to access
3971 a slot on a registered virtual subclass.

3977 in order to allow pymalloc to free more arenas. Python may give back
3978 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003979
Georg Brandl3ee81df2008-05-17 18:14:43 +00003980- Issue #2045: Fix an infinite recursion triggered when printing a
3981 subclass of collections.defaultdict, if its default_factory is set
3982 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003983
Christian Heimesf75dbef2008-02-08 00:11:31 +00003984- Fixed a minor memory leak in dictobject.c. The content of the free
3985 list was not freed on interpreter shutdown.
3986
Georg Brandl21e99f42010-03-07 15:23:59 +00003987- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003988 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003989

3991 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003992 to compact the internal free lists of pre-allocted ints and floats.
3993
Georg Brandl3ee81df2008-05-17 18:14:43 +00003994- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3995 calls. Python expected the return type int but the fork familie
3996 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003997

4008 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004009
Georg Brandl3ee81df2008-05-17 18:14:43 +00004010- Patch #1473257: generator objects gain a gi_code attribute. This is
4011 the same object as the func_code attribute of the function that
4012 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004013
Georg Brandl3ee81df2008-05-17 18:14:43 +00004014- Issue #1920: "while 0" statements were completely removed by the
4015 compiler, even in the presence of an "else" clause, which is
4016 supposed to be run when the condition is false. Now the compiler
4017 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004018
Guido van Rossumeead05f2008-01-24 18:21:02 +00004019- A few crashers fixed: weakref_in_del.py (issue #1377858);
4020 loosing_dict_ref.py (issue #1303614, test67.py);
4021 borrowed_ref_[34].py (not in tracker).
4022
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004023- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004024 suppressed while an extension is loaded by calling SetErrorMode in
4025 dynload_win.c. The error is still reported properly.
4026
Georg Brandl3ee81df2008-05-17 18:14:43 +00004027- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004028 several extension methods and modules do not work without unicode
4029 support.
4030
Georg Brandl26543b12008-01-21 18:36:51 +00004031- Issue #1882: when compiling code from a string, encoding cookies in the
4032 second line of code were not always recognized correctly.
4033
Georg Brandl14404b62008-01-19 19:27:05 +00004034- Issue #1679: "0x" was taken as a valid integer literal.
4035
Georg Brandl6caad7d2008-01-26 14:19:22 +00004036- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004037 added.
4038
Christian Heimesc94e2b52008-01-14 04:13:37 +00004039- sys.float_info / PyFloat_GetInfo: The floating point information
4040 object was converted from a dict to a specialized structseq object.
4041
Georg Brandl3ee81df2008-05-17 18:14:43 +00004042- Patch #1816: Added sys.flags structseq. It exposes the status of
4043 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004044
Georg Brandl3ee81df2008-05-17 18:14:43 +00004045- Objects/structseq.c: Implemented new structseq representation. The
4046 patch makes structseqs (e.g. the return value of os.stat) more
4047 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004048
Georg Brandl3ee81df2008-05-17 18:14:43 +00004049- Patch #1700288: added a type attribute cache that caches method
4050 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004051
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004052- Bug #1776: __import__() no longer accepts filenames on any platform.
4053 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004054
Georg Brandlaed6c662008-01-07 17:25:53 +00004055- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4056
Georg Brandl3ee81df2008-05-17 18:14:43 +00004057- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4058 envvar and sys.dont_write_bytecode attribute. All these can be set
4059 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004060
Georg Brandl3ee81df2008-05-17 18:14:43 +00004061- Improve some exception messages when Windows fails to load an
4062 extension module. Now we get for example '%1 is not a valid Win32
4063 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004064
Georg Brandl3ee81df2008-05-17 18:14:43 +00004065- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004067- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4068 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004069
Christian Heimes0a8143f2007-12-18 23:22:54 +00004070- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004071 and INF. float("nan"), float("inf") and float("-inf") now work on
4072 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004073
Georg Brandl3ee81df2008-05-17 18:14:43 +00004074- Compiler now generates simpler and faster code for dictionary
4075 literals. The oparg for BUILD_MAP now indicates an estimated
4076 dictionary size. There is a new opcode, STORE_MAP, for adding
4077 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004078
Georg Brandl3ee81df2008-05-17 18:14:43 +00004079- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004081- Issue #1620: New property decorator syntax was modifying the
4082 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004083
Georg Brandl3ee81df2008-05-17 18:14:43 +00004084- Issue #1538: Avoid copying string in split/rsplit if the split char
4085 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004086
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004087- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004088 SystemError.
4089
Nick Coghlanef01d822007-12-03 12:55:17 +00004090- PEP 366: Allow explicit relative imports when executing modules
4091 inside packages with the -m switch via a new module level
4092 __package__ attribute.
4093
Georg Brandl3ee81df2008-05-17 18:14:43 +00004094- Issue #1402: Fix a crash on exit, when another thread is still
4095 running, and if the deallocation of its frames somehow calls the
4096 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004097

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004101 attribute of an empty cell object.
4102
Georg Brandl3ee81df2008-05-17 18:14:43 +00004103- Issue #1460: The utf-7 incremental decoder did not accept truncated
4104 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004105
Georg Brandl3ee81df2008-05-17 18:14:43 +00004106- Patch #1739468: Directories and zipfiles containing a __main__.py
4107 file can now be directly executed by passing their name to the
4108 interpreter. The directory/zipfile is automatically inserted as the
4109 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004110
Georg Brandl3ee81df2008-05-17 18:14:43 +00004111- Issue #1265: Fix a problem with sys.settrace, if the tracing
4112 function uses a generator expression when at the same time the
4113 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004114
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004115- sets and frozensets now have an isdisjoint() method.
4116
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004117- optimize the performance of builtin.sum().
4118
Neal Norwitz44f326e2007-10-05 05:29:17 +00004119- Fix warnings found by the new version of the Coverity checker.
4120
Georg Brandl21e99f42010-03-07 15:23:59 +00004121- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004122 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4123 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004124
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Issue #1686386: Tuple's tp_repr did not take into account the
4126 possibility of having a self-referential tuple, which is possible
4127 from C code. Nor did object's tp_str consider that a type's tp_str
4128 could do something that could lead to an inifinite recursion.
4129 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4130 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004131
Georg Brandl3ee81df2008-05-17 18:14:43 +00004132- Issue #1164: It was possible to trigger deadlock when using the
4133 'print' statement to write to a file since the GIL was not released
4134 as needed. Now PyObject_Print() does the right thing along with
4135 various tp_print implementations of the built-in types and those in
4136 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004137
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138- Issue #1147: Exceptions were directly allowing string exceptions in
4139 their throw() method even though string exceptions no longer
4140 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004141
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142- Issue #1096: Prevent a segfault from getting the repr of a very
4143 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004144
Brett Cannon1e534b52007-09-07 04:18:30 +00004145- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004146 PyObject_Call() never calling back out to Python code to trigger
4147 recursion depth updates/checks. Required the creation of a static
4148 RuntimeError instance in case normalizing an exception put the
4149 recursion check value past its limit. Fixes crashers
4150 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004151
Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- Patch #1031213: Decode source line in SyntaxErrors back to its

4156 with %G.
4157
Georg Brandl3ee81df2008-05-17 18:14:43 +00004158- Prevent expandtabs() on string and unicode objects from causing a
4159 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004165- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004166 __*__ attributes. (Some already existed, e.g., __doc__ and
4167 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004168
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004169- Add -3 option to the interpreter to warn about features that are
4170 deprecated and will be changed/removed in Python 3.0.
4171
Georg Brandl2134e752007-05-21 20:34:16 +00004172- Patch #1686487: you can now pass any mapping after '**' in function
4173 calls.
4174
Collin Winter62903052007-05-18 23:11:24 +00004175- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004176 "except E as target:". This is to provide forwards compatibility
4177 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004178
Brett Cannon229cee22007-05-05 01:34:02 +00004179- Deprecate BaseException.message as per PEP 352.
4180
Georg Brandl3ee81df2008-05-17 18:14:43 +00004181- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004182 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004183
Vinay Sajip8549ce32007-05-06 17:53:37 +00004184- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004185 setting a plain string, ie don't expand to single letter identifiers.
4186
Raymond Hettinger13936692007-04-11 18:40:58 +00004187- Request #1191699: Slices can now be pickled.
4188
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004189- Request #1193128: str.translate() now allows a None argument for
4190 translations that only remove characters without re-mapping the
4191 remaining characters.
4192
Georg Brandl5cb76c12007-03-21 09:00:39 +00004193- Patch #1682205: a TypeError while unpacking an iterable is no longer
4194 masked by a generic one with the message "unpack non-sequence".
4195
Neal Norwitzaa754b72007-03-21 06:39:48 +00004196- Remove unused file Python/fmod.c.
4197
Guido van Rossum143b5642007-03-23 04:58:42 +00004198- Bug #1683368: The object.__init__() and object.__new__() methods are
4199 now stricter in rejecting excess arguments. The only time when
4200 either allows excess arguments is when it is not overridden and the
4201 other one is. For backwards compatibility, when both are
4202 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004203 warning later). Also, type.__init__() insists on the same signature
4204 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004205
Georg Brandl3ee81df2008-05-17 18:14:43 +00004206- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4207 object to complex using its __complex__() method before falling back
4208 to the __float__() method. Therefore, the functions in the cmath
4209 module now can operate on objects that define a __complex__()
4210 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004211
Georg Brandl3ee81df2008-05-17 18:14:43 +00004212- Patch #1623563: allow __class__ assignment for classes with
4213 __slots__. The old and the new class are still required to have the
4214 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004215
Georg Brandl3ee81df2008-05-17 18:14:43 +00004216- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004219- Patch #1462488: Python no longer segfaults when
4220 ``object.__reduce_ex__()`` is called with an object that is faking
4221 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004222
Georg Brandl3ee81df2008-05-17 18:14:43 +00004223- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00004226- Patch #1444529: the builtin compile() now accepts keyword arguments.
4227
Georg Brandl7b9c5552007-03-12 14:30:05 +00004228- Bug #1678647: write a newline after printing an exception in any
4229 case, even when converting the value to a string failed.
4230
Georg Brandl871f1bc2007-03-12 13:17:36 +00004231- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004232 its argument, if it exists. If not, it will work like before. This
4233 allows customizing the output of dir() in the presence of a
4234 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004235
Collin Winter276887b2007-03-12 16:11:39 +00004236- Patch #922167: Python no longer segfaults when faced with infinitely
4237 self-recursive reload() calls (as reported by bug #742342).
4238
Georg Brandl3ee81df2008-05-17 18:14:43 +00004239- Patch #1675981: remove unreachable code from ``type.__new__()``
4240 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004242- Patch #1491866: change the complex() constructor to allow
4243 parthensized forms. This means complex(repr(x)) now works instead of
4244 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004245

4755 ".cpp" too.
4756
Facundo Batistad918a652007-04-24 13:54:38 +00004757- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004758 the client's request was successfully received, understood, and
4759 accepted. Now in these cases no error is raised in urllib (issue
4760 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004761

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004768- Added a timeout parameter to the constructor of other protocols
4769 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4770 work started with create_connection() and timeout in httplib, and
4771 closes patch #723312.
4772
Vinay Sajip8549ce32007-05-06 17:53:37 +00004773- Patch #1676823: Added create_connection() to socket.py, which may be
4774 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004775 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004776
Martin v. Löwis0af33882007-03-23 13:27:15 +00004777- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004784- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
4785 to True (which is not the default), it visits symlinks pointing to

4789 GNOME or KDE browser, depending on whether there is a session of one

4797
Georg Brandlf66b6032007-03-14 08:27:52 +00004798- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004799 AttributeError instead of an IOError when the server's response
4800 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004801
Georg Brandl3ee81df2008-05-17 18:14:43 +00004802- Patch #957650: "%var%" environment variable references are now
4803 properly expanded in ntpath.expandvars(), also "~user" home
4804 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00004805
Georg Brandl3ee81df2008-05-17 18:14:43 +00004806- Patch #1429539: pdb now correctly initializes the __main__ module
4807 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004808 correctly now.
4809
Georg Brandlbad6f192007-03-13 21:32:56 +00004810- The nonobvious commands.getstatus() function is now deprecated.

4816
Georg Brandl3ee81df2008-05-17 18:14:43 +00004817- Patch #1530482: add pydoc.render_doc() which returns the
4818 documentation for a thing instead of paging it to stdout, which
4819 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004820
Georg Brandl3ee81df2008-05-17 18:14:43 +00004821- Patch #1533909: the timeit module now accepts callables in addition

4827 parameter which can be set to False to prevent the default
4828 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00004830- Patch #1581073: add a flag to textwrap that prevents the dropping of
4831 whitespace while wrapping.
4832
Georg Brandl92a6bae2007-03-13 17:43:32 +00004833- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004834 are set for invalid interpolation sequences that would lead to
4835 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004836

4849
Georg Brandl94fe3f52007-03-13 09:32:11 +00004850- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00004851 field names in its exception message if you try to write a record
4852 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004870

4878 returned string up to the first NUL character.
4879

4889
Georg Brandl3ee81df2008-05-17 18:14:43 +00004890- unittest now verifies more of its assumptions. In particular,
4891 TestCase and TestSuite subclasses (not instances) are no longer
4892 accepted in TestSuite.addTest(). This should cause no
4893 incompatibility since it never made sense with ordinary subclasses
4894 -- the failure just occurred later, with a more cumbersome
4895 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00004896

4904 given a unicode argument and os.listdir() returns unicode filenames.
4905
Georg Brandl3ee81df2008-05-17 18:14:43 +00004906- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00005284 time so that opening a database previously created with the DB_DUP
5285 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5286 opens. Specifically: dictionary assignment to a DB object will
5287 replace all values for a given key when the database allows
5288 duplicate values. DB users should use DB.put(k, v) when they want
5289 to store duplicates; not DB[k] = v.

5296 characters with ASCII value less than 32. Also, it correctly quotes
5297 dots only if they occur on a single line, as opposed to the previous
5298 behavior of quoting dots if they are the second character of any
5299 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005300
