Mark Dickinsone02c9d22010-05-07 13:23:18 +000021- Issue #1533: fix inconsistency in range function argument
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

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>`_.

85 error messages when accessing undefined class attributes because of the cheap
Giampaolo Rodolà902b57b2010-05-06 18:24:02 +000086 inheritance with the underlying socket object.
87
Tarek Ziadé06f78cd2010-05-05 22:21:13 +000088- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.

98 Decimal operation raises multiple signals and more than one of those
99 signals is trapped, the specification determines the order in which
100 the signals should be handled. In many cases this order wasn't
101 being followed, leading to the wrong Python exception being raised.
102
Antoine Pitrou01a255a2010-05-03 16:48:13 +0000103- Issue #7865: The close() method of :mod:`io` objects should not swallow
104 exceptions raised by the implicit flush(). Also ensure that calling

132 Sridhar Ratnakumar.
133
Antoine Pitrou53d7d062010-04-25 21:55:45 +0000134- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
135 where the method could block indefinitely if called just before the
136 event loop started running. This also fixes the occasional freezes
137 witnessed in test_httpservers.
138
Antoine Pitrouc689d962010-04-24 20:13:37 +0000139- Issue #5103: SSL handshake would ignore the socket timeout and block

152 a non-infinite timeout. Also make that method friendlier with applications
153 wanting to continue using the socket in clear-text mode, by disabling

1281- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1282 302 conformant loader) will now work correctly in most cases (they

1443What's New in Python 2.6.1
1444==========================
1445
1446*Release date: 04-Dec-2008*
1447
1448Core and Builtins
1449-----------------
1450
1451- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1452 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1453 instead of throwing a MemoryError.
1454
1455- Issue #4367: Python would segfault during compiling when the unicodedata
1456 module couldn't be imported and \N escapes were present.
1457
1458- Issue #4348: Some bytearray methods returned that didn't cause any change to
1459 the bytearray, returned the same bytearray instead of a copy.
1460
1461- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1462
1463- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1464
1465- Issue #4048: The parser module now correctly validates relative imports.
1466
1467- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1468 exec statement.
1469
1470- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1471 method does not return iterators for the 4th and 5th items.
1472
1473- Issue #4209: Enabling unicode_literals and the print_function in the same
1474 __future__ import didn't work.
1475
1476- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1477 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1478 really executed because I cannot move to such directory on win2k)
1479
1480- Issue #4069: When set.remove(element) is used with a set element, the element
1481 is temporarily replaced with an equivalent frozenset. But the eventual
1482 KeyError would always report the empty frozenset([]) as the missing key. Now
1483 it correctly refers to the initial element.
1484
1485- Fixed C99 style comments in several files. Python is now C89 compatible
1486 again.

1632
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001633- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1634
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001635- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1636 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1637 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1638 ``printf`` function, whereas PyString_FromFormat has an independent
1639 implementation and uses "%zd" on all platforms for size_t values.
1640 This makes a difference on win64, where ``printf`` needs "%Id" to display
1641 64bit values.
1642
Benjamin Peterson97179b02008-09-09 20:55:01 +00001643- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1644 error.
1645
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001646- Issue #3777: long() applied to a float object now always return a long
1647 object; previously an int would be returned for small values. the __long__
1648 method is allowed to return either an int or a long, but the behaviour of
1649 float objects should not change to respect backward compatibility.
1650
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001651- Issue #3751: str.rpartition would perform a left-partition when called with
1652 a unicode argument.
1653
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001654- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001656- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001657 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001658 was correctly parsed but parsing of subsequent arguments failed.
1659
Vinay Sajip35e3b032008-09-01 14:33:59 +00001660- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001661 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1662 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1663 when given a tuple of classes as second argument, were looking up
1664 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1665 type object.
1666
Neal Norwitz18aa3882008-08-24 05:04:52 +00001667- Fix crashes on memory allocation failure found with failmalloc.
1668
1669- Fix memory leaks found with valgrind and update suppressions file.
1670
1671- Fix compiler warnings in opt mode which would lead to invalid memory reads.

1676 function 'stringlib_contains_obj'.

1682 library targets in the Makefile.
1683
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001684- Issue #1204: The configure script now tests for additional libraries

Nick Coghland2e09382008-09-11 12:11:06 +00001709- Issue #3781: Clean up the API for warnings.catch_warnings() by having it

1736 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1737 for catch_warnings() also led to an improvement in the raising of a
1738 DeprecationWarning related to warnings.warn_explicit().

1806Core and Builtins
1807-----------------
1808
Guido van Rossumf8402962008-08-20 15:01:50 +00001809- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1810 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1811 extensions do not automatically benefit from the class attribute
1812 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1813 to their tp_flags field if they care. This is a backwards
1814 compatibility feature; in 3.0, all types will use the cache by
1815 default.
1816
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001817- Keyword arguments can now follow starred arguments. (``f(a, *args,
1818 keyword=23)`` is now valid syntax.)
1819
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001820- ctypes function pointers that are COM methods have a boolean True
1821 value again.
1822
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001823- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1824 by denying s# to parse objects that have a releasebuffer procedure,
1825 and introducing s*.
1826
Georg Brandl1e13ea92008-08-11 09:07:59 +00001827- Issue #3537: Fix an assertion failure when an empty but presized dict
1828 object was stored in the freelist.
1829
Mark Dickinsonb6467572008-08-04 21:30:09 +00001830- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1831 ValueError consistently across platforms.
1832
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001833- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1834 (64bit Unix, for example), unichr() would truncate its argument and return
1835 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1836
Neal Norwitze7d8be82008-07-31 17:17:14 +00001837- Apply security patches from Apple.
1838
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001839- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1840 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1841
Antoine Pitrou92f82162008-07-25 22:22:08 +00001842- Issue #1819: function calls with several named parameters are now on
1843 average 35% faster (as measured by pybench).
1844
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001845- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1846 the python debugger steps into a class statement: the free variables (local
1847 variables defined in an outer scope) would be deleted from the outer scope.
1848
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001849- Issue #2620: Overflow checking when allocating or reallocating memory
1850 was not always being done properly in some python types and extension
1851 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1852 all been updated to perform better checks and places in the code that
1853 would previously leak memory on the error path when such an allocation
1854 failed have been fixed.

1860
Benjamin Petersone977ad42008-08-20 01:42:01 +00001861- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1862 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1863
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001864- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1865 version reported by these tools does not necessarily follow the python
1866 version numbering scheme, so the module is less strict when parsing it.
1867
Nick Coghlanf70385a2008-08-18 12:42:46 +00001868- Issue #2235: Added Py3k warnings for types which will become unhashable
1869 under the stricter __hash__ inheritance rules in 3.0. Several types
1870 which did not meet the rules for hash invariants and were already
1871 unhashable in 3.0 have now been explicitly flagged as unhashable in
1872 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1873 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)

2002
Georg Brandl3e483f62008-07-16 22:57:41 +00002003- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2004 its methods now allow for items objects that can be converted to
2005 an integer using operator.index().
2006
Mark Dickinson64b7e502008-07-16 09:40:03 +00002007- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2008 produced a ValueError instead of giving the correct float.
2009
Eric Smitha5fa5a22008-07-16 00:11:49 +00002010- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2011 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2012
Mark Dickinson7103aa42008-07-15 19:08:33 +00002013- Issue #3008: the float type has a new instance method 'float.hex'
2014 and a new class method 'float.fromhex' to convert floating-point
2015 numbers to and from hexadecimal strings, respectively.
2016
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002017- Issue #2235: __hash__ is once again inherited by default. To allow
2018 collections.Hashable to remain meaningful in the presence of the
2019 default hash implementation (object.__hash__), it is now possible
2020 to explicit block inheritance of hash by setting __hash__=None at
2021 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2022 level.
2023
Nick Coghlanb028f502008-07-13 14:52:36 +00002024- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2025 the parent module cannot be found while performing an absolute import.
2026 This means that an incorrectly defined __package__ attribute will
2027 now only prevent relative imports in that module rather than causing
2028 all imports from that module to fail.
2029
Nick Coghlan14ff9942008-07-08 14:21:42 +00002030- Issue #2517: Allow unicode messages in Exceptions again by correctly

2040 another thread's dictionary.
2041
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002042- Issue #3004: Minor change to slice.indices(): the start and stop
2043 arguments are now treated identically, making the behaviour easier
2044 to describe and understand. For example, slice(None, -10,
2045 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2046 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2047 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00002049- Issue #3219: Calling a function with repeated keyword arguments,

2090 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002091 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002092 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002499- On MacOS X it is now possible to install the framework in 64-bit
2500 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002501 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002502
2503 This is controlled by the configure argument ``--with-universal-archs``:
2504
2505 - ``--with-universal-archs=all``: install 4-way universal
2506
2507 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2508
2509 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2510
2511 This option should be used in combination with ``--enable-universalsdk=``.
2512
2513 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 +00002563- Issue #1631171: Re-implement the 'warnings' module in C (the
2564 original Python code has been kept as backup). This will allow for
2565 using the 'warning's machinery in such places as the parser where
2566 use of pure Python code is not possible. Both the ``showarning()``
2567 and ``formatwarning()`` gain an optional 'line' argument which is
2568 not called by default for backwards-compatibility reasons. Setting
2569 ``warnings.showwarning()`` to an implementation that lacks support
2570 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002612- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002613 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002633- Issue #2550: The approach used by client/server code for obtaining
2634 ports to listen on in network-oriented tests has been refined in an
2635 effort to facilitate running multiple instances of the entire
2636 regression test suite in parallel without issue.
2637 test_support.bind_port() has been fixed such that it will always
2638 return a unique port -- which wasn't always the case with the
2639 previous implementation, especially if socket options had been set
2640 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2641 new implementation of bind_port() will actually raise an exception
2642 if it is passed an AF_INET/SOCK_STREAM socket with either the
2643 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2644 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2645 the socket it's been passed. This currently only applies to
2646 Windows. This option prevents any other sockets from binding to the
2647 host/port we've bound to, thus removing the possibility of the
2648 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2649 when a second SOCK_STREAM socket binds and accepts to a host/port
2650 that's already been bound by another socket. The optional preferred
2651 port parameter to bind_port() has been removed. Under no
2652 circumstances should tests be hard coding ports!
2653
2654 test_support.find_unused_port() has also been introduced, which will
2655 pass a temporary socket object to bind_port() in order to obtain an
2656 unused port. The temporary socket object is then closed and
2657 deleted, and the port is returned. This method should only be used
2658 for obtaining an unused port in order to pass to an external program
2659 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2660 a parameter to a server-oriented class that doesn't give you direct
2661 access to the underlying socket used.
2662
2663 Finally, test_support.HOST has been introduced, which should be used
2664 for the host argument of any relevant socket calls (i.e. bind and
2665 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002666
2667 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002668 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002669 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2670 test_asynchat and test_socket_ssl.
2671
Georg Brandl3ee81df2008-05-17 18:14:43 +00002672 It is now possible for multiple instances of the regression test
2673 suite to run in parallel without issue.

2726
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002727- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002728 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2729 Plane. This affected raw unicode literals and the
2730 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2731 this case, like normal unicode literals and the 'unicode-escape'
2732 codec.

2940-----------------
2941
Fred Drakea8ee94b2008-03-01 02:45:07 +00002942- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002943 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002945- Issue #2067: file.__exit__() now calls subclasses' close() method.
2946
2947- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002948
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002949- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002950 issue 215555 for a discussion.
2951
Eric Smitha73fbe72008-02-23 03:09:44 +00002952- Added the future_builtins module, which contains hex() and oct().
2953 These are the PEP 3127 version of these functions, designed to be
2954 compatible with the hex() and oct() builtins from Python 3.0. They
2955 differ slightly in their output formats from the existing, unchanged
2956 Python 2.6 builtins. The expected usage of the future_builtins
2957 module is:
2958 from future_builtins import hex, oct
2959
Eric Smith7ef40bf2008-02-20 23:34:22 +00002960- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2961 exponents for exponents with absolute value < 100. Follows C99
2962 standard. This is a change on Windows, which would use 3 digits.
2963 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2964 so that any alterations it does to the resulting string will be
2965 available in stringlib/formatter.h (for float.__format__).
2966
Eric Smith5a3c1352008-02-19 13:21:56 +00002967- Implemented PEP 3101, Advanced String Formatting. This adds a new
2968 builtin format(); a format() method for str and unicode; a
2969 __format__() method to object, str, unicode, int, long, float, and
2970 datetime; the class string.Formatter; and the C API
2971 PyObject_Format().
2972
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973- Fixed several potential crashes, all caused by specially crafted
2974 __del__ methods exploiting objects in temporarily inconsistent
2975 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Patch #1473257: generator objects gain a gi_code attribute. This is
3019 the same object as the func_code attribute of the function that
3020 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003021
Georg Brandl3ee81df2008-05-17 18:14:43 +00003022- Issue #1920: "while 0" statements were completely removed by the
3023 compiler, even in the presence of an "else" clause, which is
3024 supposed to be run when the condition is false. Now the compiler
3025 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003026
Guido van Rossumeead05f2008-01-24 18:21:02 +00003027- A few crashers fixed: weakref_in_del.py (issue #1377858);

3034
Georg Brandl3ee81df2008-05-17 18:14:43 +00003035- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003036 several extension methods and modules do not work without unicode
3037 support.
3038

3043
Georg Brandl6caad7d2008-01-26 14:19:22 +00003044- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003045 added.
3046
Christian Heimesc94e2b52008-01-14 04:13:37 +00003047- sys.float_info / PyFloat_GetInfo: The floating point information
3048 object was converted from a dict to a specialized structseq object.
3049
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050- Patch #1816: Added sys.flags structseq. It exposes the status of
3051 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003052
Georg Brandl3ee81df2008-05-17 18:14:43 +00003053- Objects/structseq.c: Implemented new structseq representation. The
3054 patch makes structseqs (e.g. the return value of os.stat) more
3055 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Patch #1700288: added a type attribute cache that caches method
3058 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003059
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003060- Bug #1776: __import__() no longer accepts filenames on any platform.

3066 envvar and sys.dont_write_bytecode attribute. All these can be set
3067 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003068
Georg Brandl3ee81df2008-05-17 18:14:43 +00003069- Improve some exception messages when Windows fails to load an
3070 extension module. Now we get for example '%1 is not a valid Win32
3071 application' instead of 'error code 193'.

3128
Georg Brandl5a7eca12010-03-21 19:29:04 +00003129- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3131 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003132
Georg Brandl3ee81df2008-05-17 18:14:43 +00003133- Issue #1686386: Tuple's tp_repr did not take into account the
3134 possibility of having a self-referential tuple, which is possible
3135 from C code. Nor did object's tp_str consider that a type's tp_str
3136 could do something that could lead to an inifinite recursion.
3137 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3138 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003139

3141 'print' statement to write to a file since the GIL was not released
3142 as needed. Now PyObject_Print() does the right thing along with
3143 various tp_print implementations of the built-in types and those in
3144 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003145

Georg Brandl3ee81df2008-05-17 18:14:43 +00003154 PyObject_Call() never calling back out to Python code to trigger
3155 recursion depth updates/checks. Required the creation of a static
3156 RuntimeError instance in case normalizing an exception put the
3157 recursion check value past its limit. Fixes crashers

Guido van Rossum143b5642007-03-23 04:58:42 +00003206- Bug #1683368: The object.__init__() and object.__new__() methods are
3207 now stricter in rejecting excess arguments. The only time when
3208 either allows excess arguments is when it is not overridden and the
3209 other one is. For backwards compatibility, when both are
3210 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003211 warning later). Also, type.__init__() insists on the same signature
3212 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003214- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3215 object to complex using its __complex__() method before falling back
3216 to the __float__() method. Therefore, the functions in the cmath
3217 module now can operate on objects that define a __complex__()
3218 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003236- Bug #1678647: write a newline after printing an exception in any
3237 case, even when converting the value to a string failed.
3238
Georg Brandl871f1bc2007-03-12 13:17:36 +00003239- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003240 its argument, if it exists. If not, it will work like before. This
3241 allows customizing the output of dir() in the presence of a
3242 __getattr__().

3252 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00003254- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003255 makes the filenames the warning module prints much more sensible
3256 when a PYTHONSTARTUP file is used.

3270 sq_ass_slice instead of the sq_slice slot.
3271
Georg Brandl3ee81df2008-05-17 18:14:43 +00003272- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00003324- Bug #1545497: when given an explicit base, int() did ignore NULs
3325 embedded in the string to convert.
3326
Georg Brandl846f73a2006-10-08 07:11:54 +00003327- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003375 generator expressions (x for x, in ... ) works again. Fixing this
3376 problem required changing the .pyc magic number. This means that
3377 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003807 AttributeError instead of an IOError when the server's response

3899 TestCase and TestSuite subclasses (not instances) are no longer

4178 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00004179
Georg Brandl3ee81df2008-05-17 18:14:43 +00004180- The implementation of UnicodeError objects has been simplified
4181 (start and end attributes are now stored directly as Py_ssize_t
4182 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004183
Georg Brandl3ee81df2008-05-17 18:14:43 +00004184- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4185 with RFC 3207 and forgets any knowledge obtained from the server not
4186 obtained from the TLS negotiation itself. Patch contributed by Bill
4187 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004188
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004190 that the SMTP.starttls() caller no longer needs to call ehlo()
4191 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192 does not claim to support starttls. Adds the
4193 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4194 Fenner.

4263 contents before adding elements from the iterable. This fix brings
4264 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00004265
Georg Brandl3ee81df2008-05-17 18:14:43 +00004266- Added wide char functions to msvcrt module: getwch, getwche, putwch

Georg Brandl3ee81df2008-05-17 18:14:43 +00004273- Marshal.dumps() now expects exact type matches for int, long, float,
4274 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4275 silently miscode subclasses of those types. Now, it raises a
4276 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004277

Georg Brandl3ee81df2008-05-17 18:14:43 +00004292 time so that opening a database previously created with the DB_DUP
4293 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4294 opens. Specifically: dictionary assignment to a DB object will
4295 replace all values for a given key when the database allows
4296 duplicate values. DB users should use DB.put(k, v) when they want
4297 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004298

4304 characters with ASCII value less than 32. Also, it correctly quotes
4305 dots only if they occur on a single line, as opposed to the previous
4306 behavior of quoting dots if they are the second character of any
4307 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004308

Georg Brandl3ee81df2008-05-17 18:14:43 +00004713- Removed the macfs module. It had been deprecated since Python 2.5.
4714 This lead to the deprecation of macostools.touched() as it relied
4715 solely on macfs and was a no-op under OS X.
