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

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

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

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

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

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

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

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

593Core and Builtins
594-----------------
595
Georg Brandlba83f822010-03-14 09:50:54 +0000596- The ``__complex__()`` method is now looked up on the class of instances to
597 make it consistent with other special methods.

601
Mark Dickinson1b34d252010-01-01 17:27:30 +0000602- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000603 DeprecationWarning when passed a float argument where an integer was expected.
604 These functions and methods now raise TypeError instead. The majority of the
605 effects of this change are in the extension modules, but some core functions
606 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
607 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000620- Issue #1811: Improve accuracy and cross-platform consistency for true division
621 of integers: the result of a/b is now correctly rounded for ints a and b (at
622 least on IEEE 754 platforms), and in particular does not depend on the
623 internal representation of a long.

631
Georg Brandlba83f822010-03-14 09:50:54 +0000632 These executables now work properly with the arch(1) command: ``arch -ppc
633 python`` will start a universal binary version of python in PPC mode (unlike
634 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000772- Issue #3382: 'F' formatting for float and complex now convert the result to
773 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
774 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000775
Georg Brandlba83f822010-03-14 09:50:54 +0000776- Remove switch from "%f" formatting to "%g" formatting for floats larger than
777 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000778
Georg Brandlba83f822010-03-14 09:50:54 +0000779- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
780 1e-100 used to raise OverflowError, but now gives the requested 120
781 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000782
Georg Brandlba83f822010-03-14 09:50:54 +0000783- Add Py3k warnings for parameter names in parentheses.

Georg Brandlba83f822010-03-14 09:50:54 +0000790- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
791 decimal string that's guaranteed to round back to x under correct rounding
792 (with round-half-to-even rounding mode). Previously it gave a string based on
793 rounding x to 17 decimal digits. repr(x) for a complex number behaves
794 similarly. On platforms where the correctly-rounded strtod and dtoa code is
795 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000796
Georg Brandlba83f822010-03-14 09:50:54 +0000797- Issue #7117: On almost all platforms: float-to-string and string-to-float
798 conversions within Python are now correctly rounded. Places these conversions
799 occur include: str for floats and complex numbers; the float and complex
800 constructors; old-style and new-style numeric formatting; serialization and
801 deserialization of floats and complex numbers using marshal, pickle and json;
802 parsing of float and imaginary literals in Python code; Decimal-to-float
803 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000804
Georg Brandlba83f822010-03-14 09:50:54 +0000805 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
806 providing correctly-rounded strtod and dtoa C functions. This code is
807 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
808 the C compiler. There may be a small number of platforms on which correct
809 operation of this code cannot be guaranteed, so the code is not used: notably,
810 this applies to platforms where the C double format is not IEEE 754 binary64,
811 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
812 and Python's configure script is unable to determine how to change the FPU
813 precision. On these platforms conversions use the platform strtod and dtoa,
814 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000816- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
817 uses the correctly-rounded string <-> float conversions described above (when
818 available), and so produces correctly rounded results that will display nicely
819 under the float repr. There are two related small changes: (1) round now
820 accepts any class with an ``__index__()`` method for its second argument (but
821 no longer accepts floats for the second argument), and (2) an excessively
822 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
823 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000827- Fix several issues with ``compile()``. The input can now contain Windows and

1238 gives improved memory leak detection when running under Valgrind, while taking
1239 advantage of pymalloc at other times.

2608 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

2633 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2634 when given a tuple of classes as second argument, were looking up
2635 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2636 type object.
2637
Neal Norwitz18aa3882008-08-24 05:04:52 +00002638- Fix crashes on memory allocation failure found with failmalloc.

2707 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2708 for catch_warnings() also led to an improvement in the raising of a
2709 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002775What's New in Python 2.6 beta 3?
2776================================
2777
Barry Warsaw07a4a382008-08-21 01:15:08 +00002778*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002779
2780Core and Builtins
2781-----------------
2782
Guido van Rossumf8402962008-08-20 15:01:50 +00002783- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2784 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2785 extensions do not automatically benefit from the class attribute
2786 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2787 to their tp_flags field if they care. This is a backwards
2788 compatibility feature; in 3.0, all types will use the cache by
2789 default.
2790
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002791- Keyword arguments can now follow starred arguments. (``f(a, *args,
2792 keyword=23)`` is now valid syntax.)
2793
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002794- ctypes function pointers that are COM methods have a boolean True
2795 value again.
2796
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002797- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2798 by denying s# to parse objects that have a releasebuffer procedure,
2799 and introducing s*.
2800
Georg Brandl1e13ea92008-08-11 09:07:59 +00002801- Issue #3537: Fix an assertion failure when an empty but presized dict
2802 object was stored in the freelist.
2803
Mark Dickinsonb6467572008-08-04 21:30:09 +00002804- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2805 ValueError consistently across platforms.
2806
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002807- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2808 (64bit Unix, for example), unichr() would truncate its argument and return
2809 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2810
Neal Norwitze7d8be82008-07-31 17:17:14 +00002811- Apply security patches from Apple.
2812
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002813- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2814 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2815
Antoine Pitrou92f82162008-07-25 22:22:08 +00002816- Issue #1819: function calls with several named parameters are now on
2817 average 35% faster (as measured by pybench).
2818
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002819- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2820 the python debugger steps into a class statement: the free variables (local
2821 variables defined in an outer scope) would be deleted from the outer scope.
2822
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002823- Issue #2620: Overflow checking when allocating or reallocating memory
2824 was not always being done properly in some python types and extension
2825 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2826 all been updated to perform better checks and places in the code that
2827 would previously leak memory on the error path when such an allocation
2828 failed have been fixed.

2834
Benjamin Petersone977ad42008-08-20 01:42:01 +00002835- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2836 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2837
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002838- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2839 version reported by these tools does not necessarily follow the python
2840 version numbering scheme, so the module is less strict when parsing it.
2841
Nick Coghlanf70385a2008-08-18 12:42:46 +00002842- Issue #2235: Added Py3k warnings for types which will become unhashable
2843 under the stricter __hash__ inheritance rules in 3.0. Several types
2844 which did not meet the rules for hash invariants and were already
2845 unhashable in 3.0 have now been explicitly flagged as unhashable in
2846 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2847 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2848
Brett Cannon88f801d2008-08-18 00:46:22 +00002849- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2850 imported into the module but exposed as part of the module's API.
2851
Brett Cannon7b96f072008-08-18 00:41:11 +00002852- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2853
Brett Cannon46225e72008-08-18 00:36:52 +00002854- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2857
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002858- Issue #3575: Incremental decoder's decode function now takes bytearray
2859 by using 's*' instead of 't#'.
2860
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002861- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002862 fails unicode conversion on 2nd parameter. (windows only)
2863
Facundo Batista94f243a2008-08-17 03:38:39 +00002864- Issue 2464. urllib2 now supports a malformation in the URL received
2865 in a redirect.
2866
Brett Cannonabe423e2008-08-16 21:47:07 +00002867- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002868 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002869
Facundo Batistaeb90b782008-08-16 14:44:07 +00002870- Issue #2776: fixed small issue when handling an URL with double slash
2871 after a 302 response in the case of not going through a proxy.
2872
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002873- Issue #2676: in the email package, content-type parsing was hanging on
2874 pathological input because of quadratic or exponential behaviour of a
2875 regular expression.
2876
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002877- Issue #3476: binary buffered reading through the new "io" library is now
2878 thread-safe.
2879
Brett Cannonbf3157b2008-08-14 05:00:03 +00002880- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2881 since mimetools itself is deprecated. Because modules are cached, all
2882 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2883
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002884- Issue #3134: shutil referenced undefined WindowsError symbol.
2885
Robert Schuppenies14646332008-08-10 11:01:53 +00002886- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2887 menu entries were not deleted.
2888
Brett Cannon83e81842008-08-09 23:30:55 +00002889- Copied the implementation of reduce() to _functools.reduce() to have a
2890 version that did not raise a DeprecationWarning under -3.
2891
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002892- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2893 a MemoryError rather than silently stop the iteration.
2894
Guido van Rossum59ce9012008-08-09 14:55:34 +00002895- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2896 to _sre.compile() will now be rejected. This should not affect anybody
2897 since the re.compile() function never generates invalid re-bytecode.
2898
Skip Montanaroa032bf42008-08-08 22:52:51 +00002899- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2900 upon first access it can be automatically initialized from the csv file if
2901 it wasn't initialized during instantiation.
2902
Brett Cannon3aa2a492008-08-06 22:28:09 +00002903- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2904 the reload() built-in has been removed.
2905
Brett Cannon7e30b672008-08-04 21:52:25 +00002906- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002907 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002918 asking for a specific length. This problem only affected files opened

2975-----------------
2976
Georg Brandl3e483f62008-07-16 22:57:41 +00002977- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2978 its methods now allow for items objects that can be converted to
2979 an integer using operator.index().
2980
Mark Dickinson64b7e502008-07-16 09:40:03 +00002981- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2982 produced a ValueError instead of giving the correct float.
2983
Eric Smitha5fa5a22008-07-16 00:11:49 +00002984- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2985 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2986
Mark Dickinson7103aa42008-07-15 19:08:33 +00002987- Issue #3008: the float type has a new instance method 'float.hex'
2988 and a new class method 'float.fromhex' to convert floating-point
2989 numbers to and from hexadecimal strings, respectively.
2990
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002991- Issue #2235: __hash__ is once again inherited by default. To allow
2992 collections.Hashable to remain meaningful in the presence of the
2993 default hash implementation (object.__hash__), it is now possible
2994 to explicit block inheritance of hash by setting __hash__=None at
2995 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2996 level.
2997
Nick Coghlanb028f502008-07-13 14:52:36 +00002998- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2999 the parent module cannot be found while performing an absolute import.
3000 This means that an incorrectly defined __package__ attribute will
3001 now only prevent relative imports in that module rather than causing
3002 all imports from that module to fail.
3003
Nick Coghlan14ff9942008-07-08 14:21:42 +00003004- Issue #2517: Allow unicode messages in Exceptions again by correctly

3014 another thread's dictionary.
3015
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003016- Issue #3004: Minor change to slice.indices(): the start and stop
3017 arguments are now treated identically, making the behaviour easier
3018 to describe and understand. For example, slice(None, -10,
3019 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3020 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3021 10, -1).
3022
Georg Brandl278fc502008-07-19 12:46:12 +00003023- Issue #3219: Calling a function with repeated keyword arguments,
3024 f(a=2, a=23), would not cause a syntax error. This was a regression
3025 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003063- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3064 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003065 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003066 content-length. The problem had been corrected in the 2.4 branch, but never
3067 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003082- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3495- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003496
3497- The PyString functions have been renamed to PyBytes. A batch of
3498 defines were added so that the linker still sees the original
3499 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003537- Issue #1631171: Re-implement the 'warnings' module in C (the
3538 original Python code has been kept as backup). This will allow for
3539 using the 'warning's machinery in such places as the parser where
3540 use of pure Python code is not possible. Both the ``showarning()``
3541 and ``formatwarning()`` gain an optional 'line' argument which is
3542 not called by default for backwards-compatibility reasons. Setting
3543 ``warnings.showwarning()`` to an implementation that lacks support
3544 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003586- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003587 extension modules between 32 and 64 bit platforms. See the distutls

3600 so the controlled environment will more closely mirror the typical
3601 script environment. This supports setup.py scripts that refer to
3602 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003607- Issue #2550: The approach used by client/server code for obtaining
3608 ports to listen on in network-oriented tests has been refined in an
3609 effort to facilitate running multiple instances of the entire
3610 regression test suite in parallel without issue.
3611 test_support.bind_port() has been fixed such that it will always
3612 return a unique port -- which wasn't always the case with the
3613 previous implementation, especially if socket options had been set
3614 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3615 new implementation of bind_port() will actually raise an exception
3616 if it is passed an AF_INET/SOCK_STREAM socket with either the
3617 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3618 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3619 the socket it's been passed. This currently only applies to
3620 Windows. This option prevents any other sockets from binding to the
3621 host/port we've bound to, thus removing the possibility of the
3622 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3623 when a second SOCK_STREAM socket binds and accepts to a host/port
3624 that's already been bound by another socket. The optional preferred
3625 port parameter to bind_port() has been removed. Under no
3626 circumstances should tests be hard coding ports!
3627
3628 test_support.find_unused_port() has also been introduced, which will
3629 pass a temporary socket object to bind_port() in order to obtain an
3630 unused port. The temporary socket object is then closed and
3631 deleted, and the port is returned. This method should only be used
3632 for obtaining an unused port in order to pass to an external program
3633 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3634 a parameter to a server-oriented class that doesn't give you direct
3635 access to the underlying socket used.
3636
3637 Finally, test_support.HOST has been introduced, which should be used
3638 for the host argument of any relevant socket calls (i.e. bind and
3639 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003640
3641 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003642 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003643 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3644 test_asynchat and test_socket_ssl.
3645
Georg Brandl3ee81df2008-05-17 18:14:43 +00003646 It is now possible for multiple instances of the regression test
3647 suite to run in parallel without issue.

3914-----------------
3915
Fred Drakea8ee94b2008-03-01 02:45:07 +00003916- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003917 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003922
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003923- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003924 issue 215555 for a discussion.
3925
Eric Smitha73fbe72008-02-23 03:09:44 +00003926- Added the future_builtins module, which contains hex() and oct().
3927 These are the PEP 3127 version of these functions, designed to be
3928 compatible with the hex() and oct() builtins from Python 3.0. They
3929 differ slightly in their output formats from the existing, unchanged
3930 Python 2.6 builtins. The expected usage of the future_builtins
3931 module is:
3932 from future_builtins import hex, oct
3933
Eric Smith7ef40bf2008-02-20 23:34:22 +00003934- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3935 exponents for exponents with absolute value < 100. Follows C99
3936 standard. This is a change on Windows, which would use 3 digits.
3937 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3938 so that any alterations it does to the resulting string will be
3939 available in stringlib/formatter.h (for float.__format__).
3940
Eric Smith5a3c1352008-02-19 13:21:56 +00003941- Implemented PEP 3101, Advanced String Formatting. This adds a new
3942 builtin format(); a format() method for str and unicode; a
3943 __format__() method to object, str, unicode, int, long, float, and
3944 datetime; the class string.Formatter; and the C API
3945 PyObject_Format().
3946
Georg Brandl3ee81df2008-05-17 18:14:43 +00003947- Fixed several potential crashes, all caused by specially crafted
3948 __del__ methods exploiting objects in temporarily inconsistent
3949 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003950
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003951- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003952 prevent a possible crash: an Abstract Base Class would try to access
3953 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003954

Georg Brandl3ee81df2008-05-17 18:14:43 +00003958- Clear all free lists during a gc.collect() of the highest generation
3959 in order to allow pymalloc to free more arenas. Python may give back
3960 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003961
Georg Brandl3ee81df2008-05-17 18:14:43 +00003962- Issue #2045: Fix an infinite recursion triggered when printing a
3963 subclass of collections.defaultdict, if its default_factory is set
3964 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003965
Christian Heimesf75dbef2008-02-08 00:11:31 +00003966- Fixed a minor memory leak in dictobject.c. The content of the free
3967 list was not freed on interpreter shutdown.
3968
Georg Brandl21e99f42010-03-07 15:23:59 +00003969- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00003971
Georg Brandl3ee81df2008-05-17 18:14:43 +00003972- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3973 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003974 to compact the internal free lists of pre-allocted ints and floats.
3975
Georg Brandl3ee81df2008-05-17 18:14:43 +00003976- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3977 calls. Python expected the return type int but the fork familie
3978 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003979

Georg Brandl3ee81df2008-05-17 18:14:43 +00003992- Patch #1473257: generator objects gain a gi_code attribute. This is
3993 the same object as the func_code attribute of the function that
3994 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003995
Georg Brandl3ee81df2008-05-17 18:14:43 +00003996- Issue #1920: "while 0" statements were completely removed by the
3997 compiler, even in the presence of an "else" clause, which is
3998 supposed to be run when the condition is false. Now the compiler
3999 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00004001- A few crashers fixed: weakref_in_del.py (issue #1377858);
4002 loosing_dict_ref.py (issue #1303614, test67.py);
4003 borrowed_ref_[34].py (not in tracker).
4004
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004005- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004006 suppressed while an extension is loaded by calling SetErrorMode in
4007 dynload_win.c. The error is still reported properly.
4008
Georg Brandl3ee81df2008-05-17 18:14:43 +00004009- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004010 several extension methods and modules do not work without unicode
4011 support.
4012
Georg Brandl26543b12008-01-21 18:36:51 +00004013- Issue #1882: when compiling code from a string, encoding cookies in the
4014 second line of code were not always recognized correctly.
4015
Georg Brandl14404b62008-01-19 19:27:05 +00004016- Issue #1679: "0x" was taken as a valid integer literal.
4017
Georg Brandl6caad7d2008-01-26 14:19:22 +00004018- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004019 added.
4020
Christian Heimesc94e2b52008-01-14 04:13:37 +00004021- sys.float_info / PyFloat_GetInfo: The floating point information
4022 object was converted from a dict to a specialized structseq object.
4023
Georg Brandl3ee81df2008-05-17 18:14:43 +00004024- Patch #1816: Added sys.flags structseq. It exposes the status of
4025 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004026
Georg Brandl3ee81df2008-05-17 18:14:43 +00004027- Objects/structseq.c: Implemented new structseq representation. The
4028 patch makes structseqs (e.g. the return value of os.stat) more
4029 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004030
Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Patch #1700288: added a type attribute cache that caches method
4032 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004033
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004034- Bug #1776: __import__() no longer accepts filenames on any platform.
4035 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004036
Georg Brandlaed6c662008-01-07 17:25:53 +00004037- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4038
Georg Brandl3ee81df2008-05-17 18:14:43 +00004039- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4040 envvar and sys.dont_write_bytecode attribute. All these can be set
4041 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004042
Georg Brandl3ee81df2008-05-17 18:14:43 +00004043- Improve some exception messages when Windows fails to load an
4044 extension module. Now we get for example '%1 is not a valid Win32
4045 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004046
Georg Brandl3ee81df2008-05-17 18:14:43 +00004047- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004049- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4050 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004051
Christian Heimes0a8143f2007-12-18 23:22:54 +00004052- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004053 and INF. float("nan"), float("inf") and float("-inf") now work on
4054 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004055
Georg Brandl3ee81df2008-05-17 18:14:43 +00004056- Compiler now generates simpler and faster code for dictionary
4057 literals. The oparg for BUILD_MAP now indicates an estimated
4058 dictionary size. There is a new opcode, STORE_MAP, for adding
4059 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004060
Georg Brandl3ee81df2008-05-17 18:14:43 +00004061- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00004062
Georg Brandl3ee81df2008-05-17 18:14:43 +00004063- Issue #1620: New property decorator syntax was modifying the
4064 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004065
Georg Brandl3ee81df2008-05-17 18:14:43 +00004066- Issue #1538: Avoid copying string in split/rsplit if the split char
4067 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004068
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004069- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004070 SystemError.
4071
Nick Coghlanef01d822007-12-03 12:55:17 +00004072- PEP 366: Allow explicit relative imports when executing modules
4073 inside packages with the -m switch via a new module level
4074 __package__ attribute.
4075
Georg Brandl3ee81df2008-05-17 18:14:43 +00004076- Issue #1402: Fix a crash on exit, when another thread is still
4077 running, and if the deallocation of its frames somehow calls the
4078 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004079

4081
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00004082- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004083 attribute of an empty cell object.
4084
Georg Brandl3ee81df2008-05-17 18:14:43 +00004085- Issue #1460: The utf-7 incremental decoder did not accept truncated
4086 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004087
Georg Brandl3ee81df2008-05-17 18:14:43 +00004088- Patch #1739468: Directories and zipfiles containing a __main__.py
4089 file can now be directly executed by passing their name to the
4090 interpreter. The directory/zipfile is automatically inserted as the
4091 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004092
Georg Brandl3ee81df2008-05-17 18:14:43 +00004093- Issue #1265: Fix a problem with sys.settrace, if the tracing
4094 function uses a generator expression when at the same time the
4095 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004096
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004097- sets and frozensets now have an isdisjoint() method.
4098
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004099- optimize the performance of builtin.sum().
4100
Neal Norwitz44f326e2007-10-05 05:29:17 +00004101- Fix warnings found by the new version of the Coverity checker.
4102
Georg Brandl21e99f42010-03-07 15:23:59 +00004103- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004104 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4105 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004106
Georg Brandl3ee81df2008-05-17 18:14:43 +00004107- Issue #1686386: Tuple's tp_repr did not take into account the
4108 possibility of having a self-referential tuple, which is possible
4109 from C code. Nor did object's tp_str consider that a type's tp_str
4110 could do something that could lead to an inifinite recursion.
4111 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4112 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004113
Georg Brandl3ee81df2008-05-17 18:14:43 +00004114- Issue #1164: It was possible to trigger deadlock when using the
4115 'print' statement to write to a file since the GIL was not released
4116 as needed. Now PyObject_Print() does the right thing along with
4117 various tp_print implementations of the built-in types and those in
4118 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004119
Georg Brandl3ee81df2008-05-17 18:14:43 +00004120- Issue #1147: Exceptions were directly allowing string exceptions in
4121 their throw() method even though string exceptions no longer
4122 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004123
Georg Brandl3ee81df2008-05-17 18:14:43 +00004124- Issue #1096: Prevent a segfault from getting the repr of a very
4125 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004126
Brett Cannon1e534b52007-09-07 04:18:30 +00004127- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004128 PyObject_Call() never calling back out to Python code to trigger
4129 recursion depth updates/checks. Required the creation of a static
4130 RuntimeError instance in case normalizing an exception put the
4131 recursion check value past its limit. Fixes crashers
4132 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004133
Georg Brandl3ee81df2008-05-17 18:14:43 +00004134- Patch #1031213: Decode source line in SyntaxErrors back to its
4135 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00004137- Patch #1673759: add a missing overflow check when formatting floats
4138 with %G.
4139
Georg Brandl3ee81df2008-05-17 18:14:43 +00004140- Prevent expandtabs() on string and unicode objects from causing a
4141 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00004142
Georg Brandl3ee81df2008-05-17 18:14:43 +00004143- Issue #1733488: Fix compilation of bufferobject.c on AIX.

Georg Brandla5ea6892007-06-01 11:33:33 +00004146
Neal Norwitz0ac60192007-05-27 04:08:54 +00004147- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004148 __*__ attributes. (Some already existed, e.g., __doc__ and
4149 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004150
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004151- Add -3 option to the interpreter to warn about features that are
4152 deprecated and will be changed/removed in Python 3.0.
4153
Georg Brandl2134e752007-05-21 20:34:16 +00004154- Patch #1686487: you can now pass any mapping after '**' in function
4155 calls.
4156
Collin Winter62903052007-05-18 23:11:24 +00004157- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004158 "except E as target:". This is to provide forwards compatibility
4159 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004160
Brett Cannon229cee22007-05-05 01:34:02 +00004161- Deprecate BaseException.message as per PEP 352.
4162
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004164 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004165
Vinay Sajip8549ce32007-05-06 17:53:37 +00004166- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004167 setting a plain string, ie don't expand to single letter identifiers.
4168
Raymond Hettinger13936692007-04-11 18:40:58 +00004169- Request #1191699: Slices can now be pickled.
4170
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004171- Request #1193128: str.translate() now allows a None argument for
4172 translations that only remove characters without re-mapping the
4173 remaining characters.
4174
Georg Brandl5cb76c12007-03-21 09:00:39 +00004175- Patch #1682205: a TypeError while unpacking an iterable is no longer
4176 masked by a generic one with the message "unpack non-sequence".
4177
Neal Norwitzaa754b72007-03-21 06:39:48 +00004178- Remove unused file Python/fmod.c.
4179
Guido van Rossum143b5642007-03-23 04:58:42 +00004180- Bug #1683368: The object.__init__() and object.__new__() methods are
4181 now stricter in rejecting excess arguments. The only time when
4182 either allows excess arguments is when it is not overridden and the
4183 other one is. For backwards compatibility, when both are
4184 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004185 warning later). Also, type.__init__() insists on the same signature
4186 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004187
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4189 object to complex using its __complex__() method before falling back
4190 to the __float__() method. Therefore, the functions in the cmath
4191 module now can operate on objects that define a __complex__()
4192 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004193
Georg Brandl3ee81df2008-05-17 18:14:43 +00004194- Patch #1623563: allow __class__ assignment for classes with
4195 __slots__. The old and the new class are still required to have the
4196 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004197
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198- Patch #1642547: Fix an error/crash when encountering syntax errors
4199 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004201- Patch #1462488: Python no longer segfaults when
4202 ``object.__reduce_ex__()`` is called with an object that is faking
4203 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004204
Georg Brandl3ee81df2008-05-17 18:14:43 +00004205- Patch #1680015: Don't modify __slots__ tuple if it contains an
4206 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00004208- Patch #1444529: the builtin compile() now accepts keyword arguments.
4209
Georg Brandl7b9c5552007-03-12 14:30:05 +00004210- Bug #1678647: write a newline after printing an exception in any
4211 case, even when converting the value to a string failed.
4212
Georg Brandl871f1bc2007-03-12 13:17:36 +00004213- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214 its argument, if it exists. If not, it will work like before. This
4215 allows customizing the output of dir() in the presence of a
4216 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004217
Collin Winter276887b2007-03-12 16:11:39 +00004218- Patch #922167: Python no longer segfaults when faced with infinitely
4219 self-recursive reload() calls (as reported by bug #742342).
4220
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221- Patch #1675981: remove unreachable code from ``type.__new__()``
4222 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00004223
Georg Brandl3ee81df2008-05-17 18:14:43 +00004224- Patch #1491866: change the complex() constructor to allow
4225 parthensized forms. This means complex(repr(x)) now works instead of
4226 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004227
Georg Brandlaa2321b2007-03-07 00:40:28 +00004228- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004229 makes the filenames the warning module prints much more sensible
4230 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004231
Georg Brandl49aafc92007-03-07 00:34:46 +00004232- Variant of patch #697613: don't exit the interpreter on a SystemExit
4233 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234 variable is given, but break into the interactive interpreter just
4235 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00004236
Georg Brandl3ee81df2008-05-17 18:14:43 +00004237- Patch #1638879: don't accept strings with embedded NUL bytes in

4734
Georg Brandlfb4b3b72007-04-24 15:27:13 +00004735- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
4736 (as opposed to the command line) will now write file names ending in
4737 ".cpp" too.
4738
Facundo Batistad918a652007-04-24 13:54:38 +00004739- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004740 the client's request was successfully received, understood, and
4741 accepted. Now in these cases no error is raised in urllib (issue
4742 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004743
Georg Brandl3ee81df2008-05-17 18:14:43 +00004744- Bug #1290505: time.strptime's internal cache of locale information

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004750- Added a timeout parameter to the constructor of other protocols
4751 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4752 work started with create_connection() and timeout in httplib, and
4753 closes patch #723312.
4754
Vinay Sajip8549ce32007-05-06 17:53:37 +00004755- Patch #1676823: Added create_connection() to socket.py, which may be
4756 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004757 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004758
Martin v. Löwis0af33882007-03-23 13:27:15 +00004759- Bug #978833: Revert r50844, as it broke _socketobject.dup.
4760

Georg Brandl3ee81df2008-05-17 18:14:43 +00004766- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
4767 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00004768 directories.
4769

4779
Georg Brandlf66b6032007-03-14 08:27:52 +00004780- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004781 AttributeError instead of an IOError when the server's response
4782 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004783
Georg Brandl3ee81df2008-05-17 18:14:43 +00004784- Patch #957650: "%var%" environment variable references are now
4785 properly expanded in ntpath.expandvars(), also "~user" home
4786 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00004787
Georg Brandl3ee81df2008-05-17 18:14:43 +00004788- Patch #1429539: pdb now correctly initializes the __main__ module
4789 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004790 correctly now.
4791
Georg Brandlbad6f192007-03-13 21:32:56 +00004792- The nonobvious commands.getstatus() function is now deprecated.

4798
Georg Brandl3ee81df2008-05-17 18:14:43 +00004799- Patch #1530482: add pydoc.render_doc() which returns the
4800 documentation for a thing instead of paging it to stdout, which
4801 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004802
Georg Brandl3ee81df2008-05-17 18:14:43 +00004803- Patch #1533909: the timeit module now accepts callables in addition

4809 parameter which can be set to False to prevent the default
4810 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00004811
Georg Brandl9e6b4702007-03-13 18:15:41 +00004812- Patch #1581073: add a flag to textwrap that prevents the dropping of
4813 whitespace while wrapping.
4814
Georg Brandl92a6bae2007-03-13 17:43:32 +00004815- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004816 are set for invalid interpolation sequences that would lead to
4817 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004818

4831
Georg Brandl94fe3f52007-03-13 09:32:11 +00004832- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00004833 field names in its exception message if you try to write a record
4834 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004852

4860 returned string up to the first NUL character.

4871
Georg Brandl3ee81df2008-05-17 18:14:43 +00004872- unittest now verifies more of its assumptions. In particular,
4873 TestCase and TestSuite subclasses (not instances) are no longer
4874 accepted in TestSuite.addTest(). This should cause no
4875 incompatibility since it never made sense with ordinary subclasses
4876 -- the failure just occurred later, with a more cumbersome
4877 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00004878

4886 given a unicode argument and os.listdir() returns unicode filenames.
4887
Georg Brandl3ee81df2008-05-17 18:14:43 +00004888- Patch #1673619: setup.py identifies extension modules it doesn't
4889 know how to build and those it knows how to build but that fail to
4890 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005266 time so that opening a database previously created with the DB_DUP
5267 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5268 opens. Specifically: dictionary assignment to a DB object will
5269 replace all values for a given key when the database allows
5270 duplicate values. DB users should use DB.put(k, v) when they want
5271 to store duplicates; not DB[k] = v.

5278 characters with ASCII value less than 32. Also, it correctly quotes
5279 dots only if they occur on a single line, as opposed to the previous
5280 behavior of quoting dots if they are the second character of any
5281 line.
