22 processing: any non-float non-integer argument is now converted to
23 an integer (if possible) using its __int__ method. Previously, only
24 small arguments were treated this way; larger arguments (those whose
25 __int__ was outside the range of a C long) would produce a TypeError.
26
Benjamin Petersonc218ce82010-04-16 22:43:53 +000027- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

Antoine Pitrou52ca5162010-05-21 17:22:43 +000047C-API
48-----
49
50- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
51 embedders of the interpreter to set sys.argv without also modifying
52 sys.path. This helps fix `CVE-2008-5983
53 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

Victor Stinner5b4d7ff2010-05-15 21:03:33 +000081- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
82 error messages when accessing undefined class attributes because of the cheap

84
Tarek Ziadé06f78cd2010-05-05 22:21:13 +000085- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.

95 Decimal operation raises multiple signals and more than one of those
96 signals is trapped, the specification determines the order in which
97 the signals should be handled. In many cases this order wasn't
98 being followed, leading to the wrong Python exception being raised.
99
Antoine Pitrou01a255a2010-05-03 16:48:13 +0000100- Issue #7865: The close() method of :mod:`io` objects should not swallow

130
Antoine Pitrou53d7d062010-04-25 21:55:45 +0000131- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
132 where the method could block indefinitely if called just before the
133 event loop started running. This also fixes the occasional freezes
134 witnessed in test_httpservers.
135
Antoine Pitrouc689d962010-04-24 20:13:37 +0000136- Issue #5103: SSL handshake would ignore the socket timeout and block

1242 do an explicit seek to the end of file (so that e.g. tell() returns the

1278- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1279 302 conformant loader) will now work correctly in most cases (they

1440What's New in Python 2.6.1
1441==========================
1442
1443*Release date: 04-Dec-2008*
1444
1445Core and Builtins
1446-----------------
1447
1448- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1449 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1450 instead of throwing a MemoryError.
1451
1452- Issue #4367: Python would segfault during compiling when the unicodedata
1453 module couldn't be imported and \N escapes were present.
1454
1455- Issue #4348: Some bytearray methods returned that didn't cause any change to
1456 the bytearray, returned the same bytearray instead of a copy.
1457
1458- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1459
1460- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1461
1462- Issue #4048: The parser module now correctly validates relative imports.
1463
1464- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1465 exec statement.
1466
1467- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1468 method does not return iterators for the 4th and 5th items.
1469
1470- Issue #4209: Enabling unicode_literals and the print_function in the same
1471 __future__ import didn't work.
1472
1473- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1474 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1475 really executed because I cannot move to such directory on win2k)
1476
1477- Issue #4069: When set.remove(element) is used with a set element, the element
1478 is temporarily replaced with an equivalent frozenset. But the eventual
1479 KeyError would always report the empty frozenset([]) as the missing key. Now
1480 it correctly refers to the initial element.
1481
1482- Fixed C99 style comments in several files. Python is now C89 compatible
1483 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001630- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1631
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001632- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1633 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1634 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1635 ``printf`` function, whereas PyString_FromFormat has an independent
1636 implementation and uses "%zd" on all platforms for size_t values.
1637 This makes a difference on win64, where ``printf`` needs "%Id" to display
1638 64bit values.
1639
Benjamin Peterson97179b02008-09-09 20:55:01 +00001640- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1641 error.
1642
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001643- Issue #3777: long() applied to a float object now always return a long
1644 object; previously an int would be returned for small values. the __long__
1645 method is allowed to return either an int or a long, but the behaviour of
1646 float objects should not change to respect backward compatibility.
1647
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001648- Issue #3751: str.rpartition would perform a left-partition when called with
1649 a unicode argument.
1650
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001651- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001653- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001654 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001655 was correctly parsed but parsing of subsequent arguments failed.
1656
Vinay Sajip35e3b032008-09-01 14:33:59 +00001657- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001658 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1659 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1660 when given a tuple of classes as second argument, were looking up
1661 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1662 type object.
1663
Neal Norwitz18aa3882008-08-24 05:04:52 +00001664- Fix crashes on memory allocation failure found with failmalloc.
1665
1666- Fix memory leaks found with valgrind and update suppressions file.
1667
1668- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Christian Heimes7d4c3172008-08-22 19:47:25 +00001672- Silenced another compiler warning about a used but not defined
1673 function 'stringlib_contains_obj'.

1679 library targets in the Makefile.
1680
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001681- Issue #1204: The configure script now tests for additional libraries
1682 that may be required when linking against readline. This fixes issues
1683 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1702 with statements, or when the methods are invoked in the wrong order.
1703

Nick Coghland2e09382008-09-11 12:11:06 +00001706- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001707 return a list or None rather than a custom object.

1733 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1734 for catch_warnings() also led to an improvement in the raising of a
1735 DeprecationWarning related to warnings.warn_explicit().
1736

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001802
1803Core and Builtins
1804-----------------
1805
Guido van Rossumf8402962008-08-20 15:01:50 +00001806- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1807 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1808 extensions do not automatically benefit from the class attribute
1809 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1810 to their tp_flags field if they care. This is a backwards
1811 compatibility feature; in 3.0, all types will use the cache by
1812 default.
1813
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001814- Keyword arguments can now follow starred arguments. (``f(a, *args,
1815 keyword=23)`` is now valid syntax.)
1816
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001817- ctypes function pointers that are COM methods have a boolean True
1818 value again.
1819
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001820- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1821 by denying s# to parse objects that have a releasebuffer procedure,
1822 and introducing s*.
1823
Georg Brandl1e13ea92008-08-11 09:07:59 +00001824- Issue #3537: Fix an assertion failure when an empty but presized dict
1825 object was stored in the freelist.
1826
Mark Dickinsonb6467572008-08-04 21:30:09 +00001827- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1828 ValueError consistently across platforms.
1829
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001830- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1831 (64bit Unix, for example), unichr() would truncate its argument and return
1832 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1833
Neal Norwitze7d8be82008-07-31 17:17:14 +00001834- Apply security patches from Apple.
1835
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001836- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1837 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1838
Antoine Pitrou92f82162008-07-25 22:22:08 +00001839- Issue #1819: function calls with several named parameters are now on
1840 average 35% faster (as measured by pybench).
1841
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001842- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1843 the python debugger steps into a class statement: the free variables (local
1844 variables defined in an outer scope) would be deleted from the outer scope.
1845
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001846- Issue #2620: Overflow checking when allocating or reallocating memory
1847 was not always being done properly in some python types and extension
1848 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1849 all been updated to perform better checks and places in the code that
1850 would previously leak memory on the error path when such an allocation
1851 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001856- Issue #3612: Added some missing basic types in ctypes.wintypes.
1857
Benjamin Petersone977ad42008-08-20 01:42:01 +00001858- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1859 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1860
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001861- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1862 version reported by these tools does not necessarily follow the python
1863 version numbering scheme, so the module is less strict when parsing it.
1864
Nick Coghlanf70385a2008-08-18 12:42:46 +00001865- Issue #2235: Added Py3k warnings for types which will become unhashable
1866 under the stricter __hash__ inheritance rules in 3.0. Several types
1867 which did not meet the rules for hash invariants and were already
1868 unhashable in 3.0 have now been explicitly flagged as unhashable in
1869 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1870 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)

1999
Georg Brandl3e483f62008-07-16 22:57:41 +00002000- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2001 its methods now allow for items objects that can be converted to
2002 an integer using operator.index().
2003
Mark Dickinson64b7e502008-07-16 09:40:03 +00002004- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2005 produced a ValueError instead of giving the correct float.
2006
Eric Smitha5fa5a22008-07-16 00:11:49 +00002007- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2008 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2009
Mark Dickinson7103aa42008-07-15 19:08:33 +00002010- Issue #3008: the float type has a new instance method 'float.hex'
2011 and a new class method 'float.fromhex' to convert floating-point
2012 numbers to and from hexadecimal strings, respectively.
2013
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002014- Issue #2235: __hash__ is once again inherited by default. To allow
2015 collections.Hashable to remain meaningful in the presence of the
2016 default hash implementation (object.__hash__), it is now possible
2017 to explicit block inheritance of hash by setting __hash__=None at
2018 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2019 level.
2020
Nick Coghlanb028f502008-07-13 14:52:36 +00002021- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2022 the parent module cannot be found while performing an absolute import.
2023 This means that an incorrectly defined __package__ attribute will
2024 now only prevent relative imports in that module rather than causing
2025 all imports from that module to fail.
2026
Nick Coghlan14ff9942008-07-08 14:21:42 +00002027- Issue #2517: Allow unicode messages in Exceptions again by correctly

2037 another thread's dictionary.
2038
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002039- Issue #3004: Minor change to slice.indices(): the start and stop
2040 arguments are now treated identically, making the behaviour easier
2041 to describe and understand. For example, slice(None, -10,
2042 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2043 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2044 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00002046- Issue #3219: Calling a function with repeated keyword arguments,

2087 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002088 wrong because the actual transmitted size could differ from the

2497 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002498 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002499
2500 This is controlled by the configure argument ``--with-universal-archs``:
2501
2502 - ``--with-universal-archs=all``: install 4-way universal
2503
2504 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2505
2506 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2507
2508 This option should be used in combination with ``--enable-universalsdk=``.
2509
2510 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002560- Issue #1631171: Re-implement the 'warnings' module in C (the
2561 original Python code has been kept as backup). This will allow for
2562 using the 'warning's machinery in such places as the parser where
2563 use of pure Python code is not possible. Both the ``showarning()``
2564 and ``formatwarning()`` gain an optional 'line' argument which is
2565 not called by default for backwards-compatibility reasons. Setting
2566 ``warnings.showwarning()`` to an implementation that lacks support
2567 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002630- Issue #2550: The approach used by client/server code for obtaining
2631 ports to listen on in network-oriented tests has been refined in an
2632 effort to facilitate running multiple instances of the entire
2633 regression test suite in parallel without issue.
2634 test_support.bind_port() has been fixed such that it will always
2635 return a unique port -- which wasn't always the case with the
2636 previous implementation, especially if socket options had been set
2637 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2638 new implementation of bind_port() will actually raise an exception
2639 if it is passed an AF_INET/SOCK_STREAM socket with either the
2640 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2641 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2642 the socket it's been passed. This currently only applies to
2643 Windows. This option prevents any other sockets from binding to the
2644 host/port we've bound to, thus removing the possibility of the
2645 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2646 when a second SOCK_STREAM socket binds and accepts to a host/port
2647 that's already been bound by another socket. The optional preferred
2648 port parameter to bind_port() has been removed. Under no
2649 circumstances should tests be hard coding ports!
2650
2651 test_support.find_unused_port() has also been introduced, which will
2652 pass a temporary socket object to bind_port() in order to obtain an
2653 unused port. The temporary socket object is then closed and
2654 deleted, and the port is returned. This method should only be used
2655 for obtaining an unused port in order to pass to an external program
2656 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2657 a parameter to a server-oriented class that doesn't give you direct
2658 access to the underlying socket used.
2659
2660 Finally, test_support.HOST has been introduced, which should be used
2661 for the host argument of any relevant socket calls (i.e. bind and
2662 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002663
2664 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002665 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002666 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2667 test_asynchat and test_socket_ssl.
2668
Georg Brandl3ee81df2008-05-17 18:14:43 +00002669 It is now possible for multiple instances of the regression test
2670 suite to run in parallel without issue.

2723
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002724- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002725 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2726 Plane. This affected raw unicode literals and the
2727 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2728 this case, like normal unicode literals and the 'unicode-escape'
2729 codec.

2937-----------------
2938
Fred Drakea8ee94b2008-03-01 02:45:07 +00002939- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002940 644. The mode is now inherited from the py file.

2943
2944- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002945
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002946- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002947 issue 215555 for a discussion.
2948
Eric Smitha73fbe72008-02-23 03:09:44 +00002949- Added the future_builtins module, which contains hex() and oct().
2950 These are the PEP 3127 version of these functions, designed to be
2951 compatible with the hex() and oct() builtins from Python 3.0. They
2952 differ slightly in their output formats from the existing, unchanged
2953 Python 2.6 builtins. The expected usage of the future_builtins
2954 module is:
2955 from future_builtins import hex, oct
2956
Eric Smith7ef40bf2008-02-20 23:34:22 +00002957- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2958 exponents for exponents with absolute value < 100. Follows C99
2959 standard. This is a change on Windows, which would use 3 digits.
2960 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2961 so that any alterations it does to the resulting string will be
2962 available in stringlib/formatter.h (for float.__format__).
2963
Eric Smith5a3c1352008-02-19 13:21:56 +00002964- Implemented PEP 3101, Advanced String Formatting. This adds a new
2965 builtin format(); a format() method for str and unicode; a
2966 __format__() method to object, str, unicode, int, long, float, and
2967 datetime; the class string.Formatter; and the C API
2968 PyObject_Format().
2969
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970- Fixed several potential crashes, all caused by specially crafted
2971 __del__ methods exploiting objects in temporarily inconsistent
2972 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003015- Patch #1473257: generator objects gain a gi_code attribute. This is
3016 the same object as the func_code attribute of the function that
3017 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003018
Georg Brandl3ee81df2008-05-17 18:14:43 +00003019- Issue #1920: "while 0" statements were completely removed by the
3020 compiler, even in the presence of an "else" clause, which is
3021 supposed to be run when the condition is false. Now the compiler
3022 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003023
Guido van Rossumeead05f2008-01-24 18:21:02 +00003024- A few crashers fixed: weakref_in_del.py (issue #1377858);

3031
Georg Brandl3ee81df2008-05-17 18:14:43 +00003032- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003033 several extension methods and modules do not work without unicode
3034 support.
3035

3040
Georg Brandl6caad7d2008-01-26 14:19:22 +00003041- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003042 added.
3043
Christian Heimesc94e2b52008-01-14 04:13:37 +00003044- sys.float_info / PyFloat_GetInfo: The floating point information
3045 object was converted from a dict to a specialized structseq object.
3046
Georg Brandl3ee81df2008-05-17 18:14:43 +00003047- Patch #1816: Added sys.flags structseq. It exposes the status of
3048 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003049
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050- Objects/structseq.c: Implemented new structseq representation. The
3051 patch makes structseqs (e.g. the return value of os.stat) more
3052 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003053
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054- Patch #1700288: added a type attribute cache that caches method
3055 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003056
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003057- Bug #1776: __import__() no longer accepts filenames on any platform.

3063 envvar and sys.dont_write_bytecode attribute. All these can be set
3064 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003065
Georg Brandl3ee81df2008-05-17 18:14:43 +00003066- Improve some exception messages when Windows fails to load an
3067 extension module. Now we get for example '%1 is not a valid Win32
3068 application' instead of 'error code 193'.

3125
Georg Brandl5a7eca12010-03-21 19:29:04 +00003126- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003127 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3128 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003129
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130- Issue #1686386: Tuple's tp_repr did not take into account the
3131 possibility of having a self-referential tuple, which is possible
3132 from C code. Nor did object's tp_str consider that a type's tp_str
3133 could do something that could lead to an inifinite recursion.
3134 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3135 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003136

3138 'print' statement to write to a file since the GIL was not released
3139 as needed. Now PyObject_Print() does the right thing along with
3140 various tp_print implementations of the built-in types and those in
3141 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003142

Georg Brandl3ee81df2008-05-17 18:14:43 +00003151 PyObject_Call() never calling back out to Python code to trigger
3152 recursion depth updates/checks. Required the creation of a static
3153 RuntimeError instance in case normalizing an exception put the
3154 recursion check value past its limit. Fixes crashers

Guido van Rossum143b5642007-03-23 04:58:42 +00003203- Bug #1683368: The object.__init__() and object.__new__() methods are
3204 now stricter in rejecting excess arguments. The only time when
3205 either allows excess arguments is when it is not overridden and the
3206 other one is. For backwards compatibility, when both are
3207 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003208 warning later). Also, type.__init__() insists on the same signature
3209 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003211- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3212 object to complex using its __complex__() method before falling back
3213 to the __float__() method. Therefore, the functions in the cmath
3214 module now can operate on objects that define a __complex__()
3215 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003233- Bug #1678647: write a newline after printing an exception in any
3234 case, even when converting the value to a string failed.
3235
Georg Brandl871f1bc2007-03-12 13:17:36 +00003236- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237 its argument, if it exists. If not, it will work like before. This
3238 allows customizing the output of dir() in the presence of a
3239 __getattr__().

3249 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003250
Georg Brandlaa2321b2007-03-07 00:40:28 +00003251- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003252 makes the filenames the warning module prints much more sensible
3253 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003266- Patch #1674228: when assigning a slice (old-style), check for the
3267 sq_ass_slice instead of the sq_slice slot.
3268
Georg Brandl3ee81df2008-05-17 18:14:43 +00003269- When printing an unraisable error, don't print exceptions. before
3270 the name. This duplicates the behavior whening normally printing
3271 exceptions.

Georg Brandl2c1375c2006-10-12 11:27:59 +00003321- Bug #1545497: when given an explicit base, int() did ignore NULs
3322 embedded in the string to convert.
3323
Georg Brandl846f73a2006-10-08 07:11:54 +00003324- Bug #1569998: break inside a try statement (outside a loop) is now

Neal Norwitzdac090d2006-09-05 03:53:08 +00003371- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00003372 generator expressions (x for x, in ... ) works again. Fixing this
3373 problem required changing the .pyc magic number. This means that
3374 .pyc files generated before 2.5c2 will be regenerated.

3896 TestCase and TestSuite subclasses (not instances) are no longer
3897 accepted in TestSuite.addTest(). This should cause no

Georg Brandl3ee81df2008-05-17 18:14:43 +00004177- The implementation of UnicodeError objects has been simplified
4178 (start and end attributes are now stored directly as Py_ssize_t
4179 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004180
Georg Brandl3ee81df2008-05-17 18:14:43 +00004181- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4182 with RFC 3207 and forgets any knowledge obtained from the server not
4183 obtained from the TLS negotiation itself. Patch contributed by Bill
4184 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004185
Georg Brandl3ee81df2008-05-17 18:14:43 +00004186- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004187 that the SMTP.starttls() caller no longer needs to call ehlo()
4188 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189 does not claim to support starttls. Adds the
4190 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4191 Fenner.

4260 contents before adding elements from the iterable. This fix brings
4261 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00004262
Georg Brandl3ee81df2008-05-17 18:14:43 +00004263- Added wide char functions to msvcrt module: getwch, getwche, putwch

4271 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4272 silently miscode subclasses of those types. Now, it raises a
4273 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004274

Georg Brandl3ee81df2008-05-17 18:14:43 +00004289 time so that opening a database previously created with the DB_DUP
4290 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4291 opens. Specifically: dictionary assignment to a DB object will
4292 replace all values for a given key when the database allows
4293 duplicate values. DB users should use DB.put(k, v) when they want
4294 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004295

4301 characters with ASCII value less than 32. Also, it correctly quotes
4302 dots only if they occur on a single line, as opposed to the previous
4303 behavior of quoting dots if they are the second character of any
4304 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004305

Georg Brandl3ee81df2008-05-17 18:14:43 +00004710- Removed the macfs module. It had been deprecated since Python 2.5.
4711 This lead to the deprecation of macostools.touched() as it relied
4712 solely on macfs and was a no-op under OS X.
