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
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000015- Ensure that tokenization of identifiers is not affected by locale.
16
Tarek Ziadé00002952010-04-03 08:37:59 +000017- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
18
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000019- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
20
Eric Smithd44b2fc2010-04-02 12:30:56 +000021- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
22 is called with a non-empty format string. This is an effort to
23 future-proof user code. If a derived class does not currently
24 implement __format__ but later adds its own __format__, it would
25 most likely break user code that had supplied a format string. This
26 will be changed to a DeprecationWaring in Python 3.3 and it will be
27 an error in Python 3.4.
28
Antoine Pitroua57df2c2010-03-31 21:32:15 +000029- Issue #8268: Old-style classes (not just instances) now support weak
30 references.
31
Victor Stinner6cbf90f2010-03-25 00:21:53 +000032- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
33 optimizations are disabled when --with-pydebug is used.
34
Victor Stinnerc7790ed2010-03-22 12:36:28 +000035- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000036
Benjamin Peterson96545892010-03-21 20:21:00 +000037- Issue #6474: Make error message from passing an inadequate number of keyword
38 arguments to a function correct.
39
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000040- Issue #8164: Don't allow lambda functions to have a docstring.
41
Victor Stinner66644262010-03-10 22:30:19 +000042- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000043 (SIGINT). If an error occurs while importing the site module, the error is
44 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000045 module.
46
Collin Winter001a3952010-03-18 21:54:01 +000047- Code objects now support weak references.

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +000049Library
50-------
51
Antoine Pitrouf9de5342010-04-05 21:35:07 +000052- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
53 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
54 and `ssl.OPENSSL_VERSION_NUMBER`.
55
Benjamin Peterson76a23c12010-04-04 23:23:22 +000056- Issue #8310: Allow dis to examine new style classes.
57
Mark Dickinson8a950712010-04-03 15:47:46 +000058- Issue #8257: The Decimal construct now accepts a float instance
59 directly, converting that float to a Decimal of equal value:
60
61 >>> Decimal(1.1)
62 Decimal('1.100000000000000088817841970012523233890533447265625')
63
Raymond Hettinger34c35b22010-04-03 10:22:00 +000064- collections.Counter() now supports a subtract() method.
65
Raymond Hettingera551f312010-04-04 18:34:45 +000066- the functools module now has a total_ordering() class decorator
67 to simplify the specifying rich comparisons.
68
Raymond Hettingerbb006cf2010-04-04 21:45:01 +000069- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +000070 old-style comparison functions to new-style key-functions.
71
Mark Dickinson7c63eee2010-04-02 22:27:36 +000072- Issue #8294: The Fraction constructor now accepts Decimal and float
73 instances directly.
74
Mark Dickinsone096e822010-04-02 10:17:07 +000075- Issue #7279: Comparisons involving a Decimal signaling NaN now
76 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000077 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
78 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000079
Mark Dickinson99d80962010-04-02 08:53:22 +000080- Issue #2531: Comparison operations between floats and Decimal
81 instances now return a result based on the numeric values of the
82 operands; previously they returned an arbitrary result based on
83 the relative ordering of id(float) and id(Decimal).
84
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000085- Issue #8233: When run as a script, py_compile.py optionally takes a single
86 argument `-` which tells it to read files to compile from stdin. Each line
87 is read on demand and the named file is compiled immediately. (Original
88 patch by Piotr Ożarowski).
89
90- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
91 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000092
Florent Xicluna58b65662010-03-30 16:29:03 +000093- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
94 form feed (0x0C) are now considered linebreaks, as specified in Unicode
95 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +000096 http://www.unicode.org/reports/tr14/
97
Mark Dickinson9588d992010-03-27 11:14:37 +000098- Comparisons using one of <, <=, >, >= between a complex instance and
99 a Fractions instance now raise TypeError instead of returning
100 True/False. This makes Fraction <=> complex comparisons consistent with
101 int <=> complex, float <=> complex, and complex <=> complex comparisons.
102
Michael Foorde6410c52010-03-29 20:04:23 +0000103- Addition of ``WeakSet`` to the ``weakref`` module.
104
Vinay Sajipb0623d62010-03-24 14:31:21 +0000105- logging: Added LOG_FTP to SysLogHandler and updated documentation.
106
Florent Xicluna176cda12010-03-22 22:52:11 +0000107- Issue #8205: Remove the "Modules" directory from sys.path when Python is
108 running from the build directory (POSIX only).
109
Florent Xiclunae1f4c922010-03-22 22:45:50 +0000110- Issue #7667: Fix doctest failures with non-ASCII paths.
111
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000112- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
113 didn't support chflags() (for example ZFS under FreeBSD). The error is
114 now silenced.
115
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000116- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
117 deprecated.
118
R. David Murrayc9d1a782010-03-22 15:55:09 +0000119- Issue #7860: platform.uname now reports the correct 'machine' type
120 when Python is running in WOW64 mode on 64 bit Windows.
121
Vinay Sajip804899b2010-03-22 15:29:01 +0000122- logging: Added getChild utility method to Logger and added isEnabledFor
123 method to LoggerAdapter.
124
Vinay Sajip31e928e2010-03-22 13:02:28 +0000125- Issue #8201: logging: Handle situation of non-ASCII and Unicode
126 logger names existing at the same time, causing a Unicode error
127 when configuration code attempted to sort the existing loggers.
128
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000129- Issue #8200: logging: Handle errors when multiprocessing is not
130 fully loaded when logging occurs.
131
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000132- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
133 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
134 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000135
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000136- Issue #8179: Fix macpath.realpath() on a non-existing path.
137
Florent Xicluna2e0a53f2010-03-18 21:50:06 +0000138- Issue #8024: Update the Unicode database to 5.2.
139
Antoine Pitroud7b731d2010-03-17 22:45:39 +0000140- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support
141 writing into objects supporting the new buffer API, for example bytearrays
142 or memoryviews.
143
Matthias Klose8b411682010-03-16 10:48:52 +0000144- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox

148
Matthias Klose358e7ff2010-03-15 13:42:23 +0000149- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
150 the locale.
151
Georg Brandlba83f822010-03-14 09:50:54 +0000152- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000153 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000154 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000155
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000156- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000157 for ``TimedRotatingFileHandler`` by using the modification time of an
158 existing log file to compute the next rollover time. If the log file does
159 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000160
Georg Brandlba83f822010-03-14 09:50:54 +0000161- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +0000166- Issue #7624: Fix ``isinstance(foo(), collections.Callable)`` for old-style
Florent Xicluna47627d52010-03-08 15:20:28 +0000167 classes.
168
Georg Brandlba83f822010-03-14 09:50:54 +0000169- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
170 a base64 transfer-encoded payload *after* decoding it; it no longer does.
171 This is a behavior change, so email's minor version number is now bumped, to
172 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000173
Larry Hastings3b958e32010-04-02 11:18:17 +0000174- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is

Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000188- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
189
Jesus Cea6557aac2010-03-22 14:22:26 +0000190- Issue #8156: bsddb module updated to version 4.8.4.
191 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
192 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000193
Matthias Klose817acef2010-03-15 00:02:36 +0000194- Issue #8142: Update libffi to the 3.0.9 release.
195
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000196- Issue #8300: When passing a non-integer argument to struct.pack with any
197 integer format code, struct.pack first attempts to convert the non-integer
198 using its __index__ method. If that method is non-existent or raises
199 TypeError it goes on to try the __int__ method, as described below.
200
Georg Brandlba83f822010-03-14 09:50:54 +0000201- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
202 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
203 argument's __int__ method to convert to an integer before packing. It also
204 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
205 was inconsistent: __int__ was used for some integer codes but not for others,
206 and the set of integer codes for which it was used differed between native
207 packing and standard packing.)
Mark Dickinson154b7ad2010-03-07 16:24:45 +0000208
Brian Curtin19479fa2010-04-02 21:51:37 +0000209- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a

Georg Brandlba83f822010-03-14 09:50:54 +0000215- Issue #7993: Add a test of IO packet processing bandwidth to ccbench. It
216 measures the number of UDP packets processed per second depending on the
217 number of background CPU-bound Python threads.
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000218

Martin v. Löwisbf0dfb32010-04-01 07:40:51 +0000224- Issue #8032: For gdb7, a python-gdb.py file is added to the build,
225 allowing to use advanced gdb features when debugging Python.
226
Antoine Pitrouf83b3082010-03-21 19:19:41 +0000227- Issue #1628484: The Makefile doesn't ignore the CFLAGS environment
228 variable anymore. It also forwards the LDFLAGS settings to the linker
229 when building a shared library.

239 function declaration, which was kept for backwards compatibility reasons,
240 is now removed (the macro was introduced in 1997!).
241
Larry Hastings402b73f2010-03-25 00:54:54 +0000242- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000243 from Python 3.1. All existing Python CObjects in the main distribution
244 have been converted to capsules. To address backwards-compatibility
245 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

Georg Brandlba83f822010-03-14 09:50:54 +0000491 file position when calling `truncate()`. It would previously change the file
492 position to the given argument, which goes against the tradition of

498 class used to represent files stored inside an archive. The new
499 implementation is significantly faster and can be wrapped in a
500 ``io.BufferedReader`` object for more speedups. It also solves an issue
501 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

589Core and Builtins
590-----------------
591
Georg Brandlba83f822010-03-14 09:50:54 +0000592- The ``__complex__()`` method is now looked up on the class of instances to
593 make it consistent with other special methods.

597
Mark Dickinson1b34d252010-01-01 17:27:30 +0000598- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000599 DeprecationWarning when passed a float argument where an integer was expected.
600 These functions and methods now raise TypeError instead. The majority of the
601 effects of this change are in the extension modules, but some core functions
602 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
603 and many unicode/str methods.

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

627
Georg Brandlba83f822010-03-14 09:50:54 +0000628 These executables now work properly with the arch(1) command: ``arch -ppc
629 python`` will start a universal binary version of python in PPC mode (unlike
630 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000786- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
787 decimal string that's guaranteed to round back to x under correct rounding
788 (with round-half-to-even rounding mode). Previously it gave a string based on
789 rounding x to 17 decimal digits. repr(x) for a complex number behaves
790 similarly. On platforms where the correctly-rounded strtod and dtoa code is
791 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +0000793- Issue #7117: On almost all platforms: float-to-string and string-to-float
794 conversions within Python are now correctly rounded. Places these conversions
795 occur include: str for floats and complex numbers; the float and complex
796 constructors; old-style and new-style numeric formatting; serialization and
797 deserialization of floats and complex numbers using marshal, pickle and json;
798 parsing of float and imaginary literals in Python code; Decimal-to-float
799 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000800
Georg Brandlba83f822010-03-14 09:50:54 +0000801 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
802 providing correctly-rounded strtod and dtoa C functions. This code is
803 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
804 the C compiler. There may be a small number of platforms on which correct
805 operation of this code cannot be guaranteed, so the code is not used: notably,
806 this applies to platforms where the C double format is not IEEE 754 binary64,
807 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
808 and Python's configure script is unable to determine how to change the FPU
809 precision. On these platforms conversions use the platform strtod and dtoa,
810 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000812- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
813 uses the correctly-rounded string <-> float conversions described above (when
814 available), and so produces correctly rounded results that will display nicely
815 under the float repr. There are two related small changes: (1) round now
816 accepts any class with an ``__index__()`` method for its second argument (but
817 no longer accepts floats for the second argument), and (2) an excessively
818 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
819 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00001036- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00001037 untrackable objects are not tracked by the garbage collector. This can reduce
1038 the size of collections and therefore the garbage collection overhead on
1039 long-running programs, depending on their particular use of datatypes.

1046 internal representation of integers, for performance reasons. Base 2**30 is
1047 enabled by default on 64-bit machines. Add --enable-big-digits option to
1048 configure, which overrides the default. Add sys.long_info structseq to
1049 provide information about the internal format.

Georg Brandl29c6a282009-04-05 20:23:13 +00001081- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00001082 were suppressing all exceptions. These include list(), filter(), map(),

1084
Benjamin Peterson596d3062009-01-19 15:42:23 +00001085- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00001112- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1113 existing .py counterpart, override the co_filename attributes of all code

1169
Georg Brandlba83f822010-03-14 09:50:54 +00001170- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1171 file objects with closefd=False. The file descriptor is still kept open but
1172 the file object behaves like a closed file. The ``FileIO`` object also got a

1198 this code path is really executed because I cannot move to such directory on

1225 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00002042 for *nix machines for negative handles and large int handles. Without this
2043 check it is possible to segfault the interpreter.

2402 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2403 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002602- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

2604 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2605 ``printf`` function, whereas PyString_FromFormat has an independent

2629 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2630 when given a tuple of classes as second argument, were looking up
2631 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2632 type object.
2633
Neal Norwitz18aa3882008-08-24 05:04:52 +00002634- Fix crashes on memory allocation failure found with failmalloc.

2703 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2704 for catch_warnings() also led to an improvement in the raising of a
2705 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002771What's New in Python 2.6 beta 3?
2772================================
2773
Barry Warsaw07a4a382008-08-21 01:15:08 +00002774*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002775
2776Core and Builtins
2777-----------------
2778
Guido van Rossumf8402962008-08-20 15:01:50 +00002779- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2780 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2781 extensions do not automatically benefit from the class attribute
2782 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2783 to their tp_flags field if they care. This is a backwards
2784 compatibility feature; in 3.0, all types will use the cache by
2785 default.
2786
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002787- Keyword arguments can now follow starred arguments. (``f(a, *args,
2788 keyword=23)`` is now valid syntax.)
2789
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002790- ctypes function pointers that are COM methods have a boolean True
2791 value again.
2792
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002793- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2794 by denying s# to parse objects that have a releasebuffer procedure,
2795 and introducing s*.
2796
Georg Brandl1e13ea92008-08-11 09:07:59 +00002797- Issue #3537: Fix an assertion failure when an empty but presized dict
2798 object was stored in the freelist.
2799
Mark Dickinsonb6467572008-08-04 21:30:09 +00002800- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2801 ValueError consistently across platforms.
2802
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002803- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2804 (64bit Unix, for example), unichr() would truncate its argument and return
2805 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2806
Neal Norwitze7d8be82008-07-31 17:17:14 +00002807- Apply security patches from Apple.
2808
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002809- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2810 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2811
Antoine Pitrou92f82162008-07-25 22:22:08 +00002812- Issue #1819: function calls with several named parameters are now on
2813 average 35% faster (as measured by pybench).
2814
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002815- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2816 the python debugger steps into a class statement: the free variables (local
2817 variables defined in an outer scope) would be deleted from the outer scope.
2818
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002819- Issue #2620: Overflow checking when allocating or reallocating memory
2820 was not always being done properly in some python types and extension
2821 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2822 all been updated to perform better checks and places in the code that
2823 would previously leak memory on the error path when such an allocation
2824 failed have been fixed.

2828
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002829- Issue #3612: Added some missing basic types in ctypes.wintypes.
2830
Benjamin Petersone977ad42008-08-20 01:42:01 +00002831- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2832 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2833
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002834- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2835 version reported by these tools does not necessarily follow the python
2836 version numbering scheme, so the module is less strict when parsing it.
2837
Nick Coghlanf70385a2008-08-18 12:42:46 +00002838- Issue #2235: Added Py3k warnings for types which will become unhashable
2839 under the stricter __hash__ inheritance rules in 3.0. Several types
2840 which did not meet the rules for hash invariants and were already
2841 unhashable in 3.0 have now been explicitly flagged as unhashable in
2842 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2843 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2844
Brett Cannon88f801d2008-08-18 00:46:22 +00002845- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2846 imported into the module but exposed as part of the module's API.
2847
Brett Cannon7b96f072008-08-18 00:41:11 +00002848- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2849
Brett Cannon46225e72008-08-18 00:36:52 +00002850- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002852- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2853
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002854- Issue #3575: Incremental decoder's decode function now takes bytearray
2855 by using 's*' instead of 't#'.
2856
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002857- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002858 fails unicode conversion on 2nd parameter. (windows only)
2859
Facundo Batista94f243a2008-08-17 03:38:39 +00002860- Issue 2464. urllib2 now supports a malformation in the URL received
2861 in a redirect.
2862
Brett Cannonabe423e2008-08-16 21:47:07 +00002863- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002864 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002865
Facundo Batistaeb90b782008-08-16 14:44:07 +00002866- Issue #2776: fixed small issue when handling an URL with double slash
2867 after a 302 response in the case of not going through a proxy.
2868
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002869- Issue #2676: in the email package, content-type parsing was hanging on
2870 pathological input because of quadratic or exponential behaviour of a
2871 regular expression.
2872
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002873- Issue #3476: binary buffered reading through the new "io" library is now
2874 thread-safe.
2875
Brett Cannonbf3157b2008-08-14 05:00:03 +00002876- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2877 since mimetools itself is deprecated. Because modules are cached, all
2878 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2879
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002880- Issue #3134: shutil referenced undefined WindowsError symbol.
2881
Robert Schuppenies14646332008-08-10 11:01:53 +00002882- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2883 menu entries were not deleted.
2884
Brett Cannon83e81842008-08-09 23:30:55 +00002885- Copied the implementation of reduce() to _functools.reduce() to have a
2886 version that did not raise a DeprecationWarning under -3.
2887
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002888- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2889 a MemoryError rather than silently stop the iteration.
2890
Guido van Rossum59ce9012008-08-09 14:55:34 +00002891- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2892 to _sre.compile() will now be rejected. This should not affect anybody
2893 since the re.compile() function never generates invalid re-bytecode.
2894
Skip Montanaroa032bf42008-08-08 22:52:51 +00002895- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2896 upon first access it can be automatically initialized from the csv file if
2897 it wasn't initialized during instantiation.
2898
Brett Cannon3aa2a492008-08-06 22:28:09 +00002899- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2900 the reload() built-in has been removed.
2901
Brett Cannon7e30b672008-08-04 21:52:25 +00002902- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002903 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002914 asking for a specific length. This problem only affected files opened

2971-----------------
2972
Georg Brandl3e483f62008-07-16 22:57:41 +00002973- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2974 its methods now allow for items objects that can be converted to
2975 an integer using operator.index().
2976
Mark Dickinson64b7e502008-07-16 09:40:03 +00002977- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2978 produced a ValueError instead of giving the correct float.
2979
Eric Smitha5fa5a22008-07-16 00:11:49 +00002980- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2981 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2982
Mark Dickinson7103aa42008-07-15 19:08:33 +00002983- Issue #3008: the float type has a new instance method 'float.hex'
2984 and a new class method 'float.fromhex' to convert floating-point
2985 numbers to and from hexadecimal strings, respectively.
2986
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002987- Issue #2235: __hash__ is once again inherited by default. To allow
2988 collections.Hashable to remain meaningful in the presence of the
2989 default hash implementation (object.__hash__), it is now possible
2990 to explicit block inheritance of hash by setting __hash__=None at
2991 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2992 level.
2993
Nick Coghlanb028f502008-07-13 14:52:36 +00002994- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2995 the parent module cannot be found while performing an absolute import.
2996 This means that an incorrectly defined __package__ attribute will
2997 now only prevent relative imports in that module rather than causing
2998 all imports from that module to fail.
2999
Nick Coghlan14ff9942008-07-08 14:21:42 +00003000- Issue #2517: Allow unicode messages in Exceptions again by correctly

3010 another thread's dictionary.
3011
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003012- Issue #3004: Minor change to slice.indices(): the start and stop
3013 arguments are now treated identically, making the behaviour easier
3014 to describe and understand. For example, slice(None, -10,
3015 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3016 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3017 10, -1).
3018
Georg Brandl278fc502008-07-19 12:46:12 +00003019- Issue #3219: Calling a function with repeated keyword arguments,
3020 f(a=2, a=23), would not cause a syntax error. This was a regression
3021 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003059- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3060 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003061 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003062 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003078- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3488
Georg Brandl74a1dea2008-05-28 11:21:39 +00003489- Add ``PyType_Modified()`` as a public API to clear the type cache.
3490
3491- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003492
3493- The PyString functions have been renamed to PyBytes. A batch of
3494 defines were added so that the linker still sees the original
3495 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003533- Issue #1631171: Re-implement the 'warnings' module in C (the
3534 original Python code has been kept as backup). This will allow for
3535 using the 'warning's machinery in such places as the parser where
3536 use of pure Python code is not possible. Both the ``showarning()``
3537 and ``formatwarning()`` gain an optional 'line' argument which is
3538 not called by default for backwards-compatibility reasons. Setting
3539 ``warnings.showwarning()`` to an implementation that lacks support
3540 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003565- The getpass module has been improved on Unix. It now uses /dev/tty
3566 by default and uses stderr instead of stdout. A GetPassWarning is
3567 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003582- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003583 extension modules between 32 and 64 bit platforms. See the distutls

3596 so the controlled environment will more closely mirror the typical
3597 script environment. This supports setup.py scripts that refer to
3598 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003603- Issue #2550: The approach used by client/server code for obtaining
3604 ports to listen on in network-oriented tests has been refined in an
3605 effort to facilitate running multiple instances of the entire
3606 regression test suite in parallel without issue.
3607 test_support.bind_port() has been fixed such that it will always
3608 return a unique port -- which wasn't always the case with the
3609 previous implementation, especially if socket options had been set
3610 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3611 new implementation of bind_port() will actually raise an exception
3612 if it is passed an AF_INET/SOCK_STREAM socket with either the
3613 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3614 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3615 the socket it's been passed. This currently only applies to
3616 Windows. This option prevents any other sockets from binding to the
3617 host/port we've bound to, thus removing the possibility of the
3618 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3619 when a second SOCK_STREAM socket binds and accepts to a host/port
3620 that's already been bound by another socket. The optional preferred
3621 port parameter to bind_port() has been removed. Under no
3622 circumstances should tests be hard coding ports!
3623
3624 test_support.find_unused_port() has also been introduced, which will
3625 pass a temporary socket object to bind_port() in order to obtain an
3626 unused port. The temporary socket object is then closed and
3627 deleted, and the port is returned. This method should only be used
3628 for obtaining an unused port in order to pass to an external program
3629 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3630 a parameter to a server-oriented class that doesn't give you direct
3631 access to the underlying socket used.
3632
3633 Finally, test_support.HOST has been introduced, which should be used
3634 for the host argument of any relevant socket calls (i.e. bind and
3635 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003636
3637 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003638 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003639 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3640 test_asynchat and test_socket_ssl.
3641
Georg Brandl3ee81df2008-05-17 18:14:43 +00003642 It is now possible for multiple instances of the regression test
3643 suite to run in parallel without issue.

3910-----------------
3911
Fred Drakea8ee94b2008-03-01 02:45:07 +00003912- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003913 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003918
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003919- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003920 issue 215555 for a discussion.
3921
Eric Smitha73fbe72008-02-23 03:09:44 +00003922- Added the future_builtins module, which contains hex() and oct().
3923 These are the PEP 3127 version of these functions, designed to be
3924 compatible with the hex() and oct() builtins from Python 3.0. They
3925 differ slightly in their output formats from the existing, unchanged
3926 Python 2.6 builtins. The expected usage of the future_builtins
3927 module is:
3928 from future_builtins import hex, oct
3929
Eric Smith7ef40bf2008-02-20 23:34:22 +00003930- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3931 exponents for exponents with absolute value < 100. Follows C99
3932 standard. This is a change on Windows, which would use 3 digits.
3933 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3934 so that any alterations it does to the resulting string will be
3935 available in stringlib/formatter.h (for float.__format__).
3936
Eric Smith5a3c1352008-02-19 13:21:56 +00003937- Implemented PEP 3101, Advanced String Formatting. This adds a new
3938 builtin format(); a format() method for str and unicode; a
3939 __format__() method to object, str, unicode, int, long, float, and
3940 datetime; the class string.Formatter; and the C API
3941 PyObject_Format().
3942
Georg Brandl3ee81df2008-05-17 18:14:43 +00003943- Fixed several potential crashes, all caused by specially crafted
3944 __del__ methods exploiting objects in temporarily inconsistent
3945 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003946
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003947- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003948 prevent a possible crash: an Abstract Base Class would try to access
3949 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003950

Georg Brandl3ee81df2008-05-17 18:14:43 +00003954- Clear all free lists during a gc.collect() of the highest generation
3955 in order to allow pymalloc to free more arenas. Python may give back
3956 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003957
Georg Brandl3ee81df2008-05-17 18:14:43 +00003958- Issue #2045: Fix an infinite recursion triggered when printing a
3959 subclass of collections.defaultdict, if its default_factory is set
3960 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003961
Christian Heimesf75dbef2008-02-08 00:11:31 +00003962- Fixed a minor memory leak in dictobject.c. The content of the free
3963 list was not freed on interpreter shutdown.
3964
Georg Brandl21e99f42010-03-07 15:23:59 +00003965- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003966 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003967
Georg Brandl3ee81df2008-05-17 18:14:43 +00003968- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3969 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003970 to compact the internal free lists of pre-allocted ints and floats.
3971
Georg Brandl3ee81df2008-05-17 18:14:43 +00003972- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3973 calls. Python expected the return type int but the fork familie
3974 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003975

3986 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003987
Georg Brandl3ee81df2008-05-17 18:14:43 +00003988- Patch #1473257: generator objects gain a gi_code attribute. This is
3989 the same object as the func_code attribute of the function that
3990 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003991
Georg Brandl3ee81df2008-05-17 18:14:43 +00003992- Issue #1920: "while 0" statements were completely removed by the
3993 compiler, even in the presence of an "else" clause, which is
3994 supposed to be run when the condition is false. Now the compiler
3995 correctly emits bytecode for the "else" suite.

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004001- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004002 suppressed while an extension is loaded by calling SetErrorMode in
4003 dynload_win.c. The error is still reported properly.
4004
Georg Brandl3ee81df2008-05-17 18:14:43 +00004005- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004006 several extension methods and modules do not work without unicode
4007 support.
4008
Georg Brandl26543b12008-01-21 18:36:51 +00004009- Issue #1882: when compiling code from a string, encoding cookies in the
4010 second line of code were not always recognized correctly.
4011
Georg Brandl14404b62008-01-19 19:27:05 +00004012- Issue #1679: "0x" was taken as a valid integer literal.
4013
Georg Brandl6caad7d2008-01-26 14:19:22 +00004014- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004015 added.
4016
Christian Heimesc94e2b52008-01-14 04:13:37 +00004017- sys.float_info / PyFloat_GetInfo: The floating point information
4018 object was converted from a dict to a specialized structseq object.
4019
Georg Brandl3ee81df2008-05-17 18:14:43 +00004020- Patch #1816: Added sys.flags structseq. It exposes the status of
4021 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004022
Georg Brandl3ee81df2008-05-17 18:14:43 +00004023- Objects/structseq.c: Implemented new structseq representation. The
4024 patch makes structseqs (e.g. the return value of os.stat) more
4025 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004026
Georg Brandl3ee81df2008-05-17 18:14:43 +00004027- Patch #1700288: added a type attribute cache that caches method
4028 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004029
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004030- Bug #1776: __import__() no longer accepts filenames on any platform.
4031 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004032
Georg Brandlaed6c662008-01-07 17:25:53 +00004033- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4034
Georg Brandl3ee81df2008-05-17 18:14:43 +00004035- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4036 envvar and sys.dont_write_bytecode attribute. All these can be set
4037 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004038
Georg Brandl3ee81df2008-05-17 18:14:43 +00004039- Improve some exception messages when Windows fails to load an
4040 extension module. Now we get for example '%1 is not a valid Win32
4041 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004042
Georg Brandl3ee81df2008-05-17 18:14:43 +00004043- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004045- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4046 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004047
Christian Heimes0a8143f2007-12-18 23:22:54 +00004048- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004049 and INF. float("nan"), float("inf") and float("-inf") now work on
4050 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004051
Georg Brandl3ee81df2008-05-17 18:14:43 +00004052- Compiler now generates simpler and faster code for dictionary
4053 literals. The oparg for BUILD_MAP now indicates an estimated
4054 dictionary size. There is a new opcode, STORE_MAP, for adding
4055 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004056
Georg Brandl3ee81df2008-05-17 18:14:43 +00004057- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00004058
Georg Brandl3ee81df2008-05-17 18:14:43 +00004059- Issue #1620: New property decorator syntax was modifying the
4060 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004061
Georg Brandl3ee81df2008-05-17 18:14:43 +00004062- Issue #1538: Avoid copying string in split/rsplit if the split char
4063 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004064
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004065- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004066 SystemError.
4067
Nick Coghlanef01d822007-12-03 12:55:17 +00004068- PEP 366: Allow explicit relative imports when executing modules
4069 inside packages with the -m switch via a new module level
4070 __package__ attribute.
4071
Georg Brandl3ee81df2008-05-17 18:14:43 +00004072- Issue #1402: Fix a crash on exit, when another thread is still
4073 running, and if the deallocation of its frames somehow calls the
4074 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004075

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004079 attribute of an empty cell object.
4080
Georg Brandl3ee81df2008-05-17 18:14:43 +00004081- Issue #1460: The utf-7 incremental decoder did not accept truncated
4082 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004083
Georg Brandl3ee81df2008-05-17 18:14:43 +00004084- Patch #1739468: Directories and zipfiles containing a __main__.py
4085 file can now be directly executed by passing their name to the
4086 interpreter. The directory/zipfile is automatically inserted as the
4087 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004088
Georg Brandl3ee81df2008-05-17 18:14:43 +00004089- Issue #1265: Fix a problem with sys.settrace, if the tracing
4090 function uses a generator expression when at the same time the
4091 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004092
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004093- sets and frozensets now have an isdisjoint() method.
4094
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004095- optimize the performance of builtin.sum().
4096
Neal Norwitz44f326e2007-10-05 05:29:17 +00004097- Fix warnings found by the new version of the Coverity checker.
4098
Georg Brandl21e99f42010-03-07 15:23:59 +00004099- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004100 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4101 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004102
Georg Brandl3ee81df2008-05-17 18:14:43 +00004103- Issue #1686386: Tuple's tp_repr did not take into account the
4104 possibility of having a self-referential tuple, which is possible
4105 from C code. Nor did object's tp_str consider that a type's tp_str
4106 could do something that could lead to an inifinite recursion.
4107 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4108 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004109
Georg Brandl3ee81df2008-05-17 18:14:43 +00004110- Issue #1164: It was possible to trigger deadlock when using the
4111 'print' statement to write to a file since the GIL was not released
4112 as needed. Now PyObject_Print() does the right thing along with
4113 various tp_print implementations of the built-in types and those in
4114 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004115
Georg Brandl3ee81df2008-05-17 18:14:43 +00004116- Issue #1147: Exceptions were directly allowing string exceptions in
4117 their throw() method even though string exceptions no longer
4118 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004119
Georg Brandl3ee81df2008-05-17 18:14:43 +00004120- Issue #1096: Prevent a segfault from getting the repr of a very
4121 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004122
Brett Cannon1e534b52007-09-07 04:18:30 +00004123- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004124 PyObject_Call() never calling back out to Python code to trigger
4125 recursion depth updates/checks. Required the creation of a static
4126 RuntimeError instance in case normalizing an exception put the
4127 recursion check value past its limit. Fixes crashers
4128 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004129
Georg Brandl3ee81df2008-05-17 18:14:43 +00004130- Patch #1031213: Decode source line in SyntaxErrors back to its
4131 original source encoding.

4134 with %G.
4135
Georg Brandl3ee81df2008-05-17 18:14:43 +00004136- Prevent expandtabs() on string and unicode objects from causing a
4137 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00004138

Georg Brandla5ea6892007-06-01 11:33:33 +00004142
Neal Norwitz0ac60192007-05-27 04:08:54 +00004143- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004144 __*__ attributes. (Some already existed, e.g., __doc__ and
4145 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004146
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004147- Add -3 option to the interpreter to warn about features that are
4148 deprecated and will be changed/removed in Python 3.0.
4149
Georg Brandl2134e752007-05-21 20:34:16 +00004150- Patch #1686487: you can now pass any mapping after '**' in function
4151 calls.
4152
Collin Winter62903052007-05-18 23:11:24 +00004153- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004154 "except E as target:". This is to provide forwards compatibility
4155 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004156
Brett Cannon229cee22007-05-05 01:34:02 +00004157- Deprecate BaseException.message as per PEP 352.
4158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004160 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004161
Vinay Sajip8549ce32007-05-06 17:53:37 +00004162- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004163 setting a plain string, ie don't expand to single letter identifiers.
4164
Raymond Hettinger13936692007-04-11 18:40:58 +00004165- Request #1191699: Slices can now be pickled.
4166
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004167- Request #1193128: str.translate() now allows a None argument for
4168 translations that only remove characters without re-mapping the
4169 remaining characters.
4170
Georg Brandl5cb76c12007-03-21 09:00:39 +00004171- Patch #1682205: a TypeError while unpacking an iterable is no longer
4172 masked by a generic one with the message "unpack non-sequence".
4173
Neal Norwitzaa754b72007-03-21 06:39:48 +00004174- Remove unused file Python/fmod.c.
4175
Guido van Rossum143b5642007-03-23 04:58:42 +00004176- Bug #1683368: The object.__init__() and object.__new__() methods are
4177 now stricter in rejecting excess arguments. The only time when
4178 either allows excess arguments is when it is not overridden and the
4179 other one is. For backwards compatibility, when both are
4180 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004181 warning later). Also, type.__init__() insists on the same signature
4182 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004183
Georg Brandl3ee81df2008-05-17 18:14:43 +00004184- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4185 object to complex using its __complex__() method before falling back
4186 to the __float__() method. Therefore, the functions in the cmath
4187 module now can operate on objects that define a __complex__()
4188 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Patch #1623563: allow __class__ assignment for classes with
4191 __slots__. The old and the new class are still required to have the
4192 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004193
Georg Brandl3ee81df2008-05-17 18:14:43 +00004194- Patch #1642547: Fix an error/crash when encountering syntax errors
4195 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Patch #1462488: Python no longer segfaults when
4198 ``object.__reduce_ex__()`` is called with an object that is faking
4199 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004200
Georg Brandl3ee81df2008-05-17 18:14:43 +00004201- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00004204- Patch #1444529: the builtin compile() now accepts keyword arguments.
4205
Georg Brandl7b9c5552007-03-12 14:30:05 +00004206- Bug #1678647: write a newline after printing an exception in any
4207 case, even when converting the value to a string failed.
4208
Georg Brandl871f1bc2007-03-12 13:17:36 +00004209- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004210 its argument, if it exists. If not, it will work like before. This
4211 allows customizing the output of dir() in the presence of a
4212 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004213
Collin Winter276887b2007-03-12 16:11:39 +00004214- Patch #922167: Python no longer segfaults when faced with infinitely
4215 self-recursive reload() calls (as reported by bug #742342).
4216
Georg Brandl3ee81df2008-05-17 18:14:43 +00004217- Patch #1675981: remove unreachable code from ``type.__new__()``
4218 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00004219
Georg Brandl3ee81df2008-05-17 18:14:43 +00004220- Patch #1491866: change the complex() constructor to allow
4221 parthensized forms. This means complex(repr(x)) now works instead of
4222 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004223
Georg Brandlaa2321b2007-03-07 00:40:28 +00004224- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225 makes the filenames the warning module prints much more sensible
4226 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004227
Georg Brandl49aafc92007-03-07 00:34:46 +00004228- Variant of patch #697613: don't exit the interpreter on a SystemExit
4229 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004230 variable is given, but break into the interactive interpreter just
4231 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00004232
Georg Brandl3ee81df2008-05-17 18:14:43 +00004233- Patch #1638879: don't accept strings with embedded NUL bytes in

4730
Georg Brandlfb4b3b72007-04-24 15:27:13 +00004731- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
4732 (as opposed to the command line) will now write file names ending in
4733 ".cpp" too.
4734
Facundo Batistad918a652007-04-24 13:54:38 +00004735- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004736 the client's request was successfully received, understood, and
4737 accepted. Now in these cases no error is raised in urllib (issue
4738 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004739

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004746- Added a timeout parameter to the constructor of other protocols
4747 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4748 work started with create_connection() and timeout in httplib, and
4749 closes patch #723312.
4750
Vinay Sajip8549ce32007-05-06 17:53:37 +00004751- Patch #1676823: Added create_connection() to socket.py, which may be
4752 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004753 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004754
Martin v. Löwis0af33882007-03-23 13:27:15 +00004755- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004762- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
4763 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00004764 directories.
4765

4775
Georg Brandlf66b6032007-03-14 08:27:52 +00004776- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004777 AttributeError instead of an IOError when the server's response
4778 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004779
Georg Brandl3ee81df2008-05-17 18:14:43 +00004780- Patch #957650: "%var%" environment variable references are now
4781 properly expanded in ntpath.expandvars(), also "~user" home
4782 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00004783
Georg Brandl3ee81df2008-05-17 18:14:43 +00004784- Patch #1429539: pdb now correctly initializes the __main__ module
4785 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004786 correctly now.
4787
Georg Brandlbad6f192007-03-13 21:32:56 +00004788- The nonobvious commands.getstatus() function is now deprecated.

4794
Georg Brandl3ee81df2008-05-17 18:14:43 +00004795- Patch #1530482: add pydoc.render_doc() which returns the
4796 documentation for a thing instead of paging it to stdout, which
4797 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004798
Georg Brandl3ee81df2008-05-17 18:14:43 +00004799- Patch #1533909: the timeit module now accepts callables in addition

4805 parameter which can be set to False to prevent the default
4806 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00004807
Georg Brandl9e6b4702007-03-13 18:15:41 +00004808- Patch #1581073: add a flag to textwrap that prevents the dropping of
4809 whitespace while wrapping.
4810
Georg Brandl92a6bae2007-03-13 17:43:32 +00004811- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004812 are set for invalid interpolation sequences that would lead to
4813 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004814

4827
Georg Brandl94fe3f52007-03-13 09:32:11 +00004828- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00004829 field names in its exception message if you try to write a record
4830 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004848

4856 returned string up to the first NUL character.

4867
Georg Brandl3ee81df2008-05-17 18:14:43 +00004868- unittest now verifies more of its assumptions. In particular,
4869 TestCase and TestSuite subclasses (not instances) are no longer
4870 accepted in TestSuite.addTest(). This should cause no
4871 incompatibility since it never made sense with ordinary subclasses
4872 -- the failure just occurred later, with a more cumbersome
4873 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00004874

4882 given a unicode argument and os.listdir() returns unicode filenames.
4883
Georg Brandl3ee81df2008-05-17 18:14:43 +00004884- Patch #1673619: setup.py identifies extension modules it doesn't
4885 know how to build and those it knows how to build but that fail to
4886 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005262 time so that opening a database previously created with the DB_DUP
5263 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5264 opens. Specifically: dictionary assignment to a DB object will
5265 replace all values for a given key when the database allows
5266 duplicate values. DB users should use DB.put(k, v) when they want
5267 to store duplicates; not DB[k] = v.

5274 characters with ASCII value less than 32. Also, it correctly quotes
5275 dots only if they occur on a single line, as opposed to the previous
5276 behavior of quoting dots if they are the second character of any
5277 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005655- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5656 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
