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

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>`_.

101 ASCII with backslashreplace error handler if str(value) failed
102
Mark Dickinson1cdfa5f2010-05-04 14:30:32 +0000103- Issue #8567: Fix precedence of signals in Decimal module: when a
104 Decimal operation raises multiple signals and more than one of those
105 signals is trapped, the specification determines the order in which
106 the signals should be handled. In many cases this order wasn't
107 being followed, leading to the wrong Python exception being raised.
108
Antoine Pitrou01a255a2010-05-03 16:48:13 +0000109- Issue #7865: The close() method of :mod:`io` objects should not swallow

119 not just SIGCHLD.
120
Victor Stinner5b4d7ff2010-05-15 21:03:33 +0000121- Issue #8577: distutils.sysconfig.get_python_inc() now makes a difference
Tarek Ziadé68ca24b2010-04-30 12:18:51 +0000122 between the build dir and the source dir when looking for "python.h" or

138 Sridhar Ratnakumar.
139
Antoine Pitrou53d7d062010-04-25 21:55:45 +0000140- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
141 where the method could block indefinitely if called just before the
142 event loop started running. This also fixes the occasional freezes
143 witnessed in test_httpservers.
144
Antoine Pitrouc689d962010-04-24 20:13:37 +0000145- Issue #5103: SSL handshake would ignore the socket timeout and block

158 a non-infinite timeout. Also make that method friendlier with applications
159 wanting to continue using the socket in clear-text mode, by disabling
160 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

1251 do an explicit seek to the end of file (so that e.g. tell() returns the

1253 traditional 2.x file object.

1286
1287- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1288 302 conformant loader) will now work correctly in most cases (they
1289 are still subject to the constraints that exist for all code running
1290 from inside a module loaded via a PEP 302 loader and attempting to

1449What's New in Python 2.6.1
1450==========================
1451
1452*Release date: 04-Dec-2008*
1453
1454Core and Builtins
1455-----------------
1456
1457- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1458 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1459 instead of throwing a MemoryError.
1460
1461- Issue #4367: Python would segfault during compiling when the unicodedata
1462 module couldn't be imported and \N escapes were present.
1463
1464- Issue #4348: Some bytearray methods returned that didn't cause any change to
1465 the bytearray, returned the same bytearray instead of a copy.
1466
1467- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1468
1469- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1470
1471- Issue #4048: The parser module now correctly validates relative imports.
1472
1473- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1474 exec statement.
1475
1476- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1477 method does not return iterators for the 4th and 5th items.
1478
1479- Issue #4209: Enabling unicode_literals and the print_function in the same
1480 __future__ import didn't work.
1481
1482- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1483 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1484 really executed because I cannot move to such directory on win2k)
1485
1486- Issue #4069: When set.remove(element) is used with a set element, the element
1487 is temporarily replaced with an equivalent frozenset. But the eventual
1488 KeyError would always report the empty frozenset([]) as the missing key. Now
1489 it correctly refers to the initial element.
1490
1491- Fixed C99 style comments in several files. Python is now C89 compatible
1492 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001639- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1640
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001641- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1642 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1643 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1644 ``printf`` function, whereas PyString_FromFormat has an independent
1645 implementation and uses "%zd" on all platforms for size_t values.
1646 This makes a difference on win64, where ``printf`` needs "%Id" to display
1647 64bit values.
1648
Benjamin Peterson97179b02008-09-09 20:55:01 +00001649- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1650 error.
1651
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001652- Issue #3777: long() applied to a float object now always return a long
1653 object; previously an int would be returned for small values. the __long__
1654 method is allowed to return either an int or a long, but the behaviour of
1655 float objects should not change to respect backward compatibility.
1656
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001657- Issue #3751: str.rpartition would perform a left-partition when called with
1658 a unicode argument.
1659
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001660- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001662- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001663 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001664 was correctly parsed but parsing of subsequent arguments failed.
1665
Vinay Sajip35e3b032008-09-01 14:33:59 +00001666- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001667 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1668 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1669 when given a tuple of classes as second argument, were looking up
1670 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1671 type object.
1672
Neal Norwitz18aa3882008-08-24 05:04:52 +00001673- Fix crashes on memory allocation failure found with failmalloc.
1674
1675- Fix memory leaks found with valgrind and update suppressions file.
1676
1677- Fix compiler warnings in opt mode which would lead to invalid memory reads.

1682 function 'stringlib_contains_obj'.

1742 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1743 for catch_warnings() also led to an improvement in the raising of a
1744 DeprecationWarning related to warnings.warn_explicit().

1812Core and Builtins
1813-----------------
1814
Guido van Rossumf8402962008-08-20 15:01:50 +00001815- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1816 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1817 extensions do not automatically benefit from the class attribute
1818 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1819 to their tp_flags field if they care. This is a backwards
1820 compatibility feature; in 3.0, all types will use the cache by
1821 default.
1822
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001823- Keyword arguments can now follow starred arguments. (``f(a, *args,
1824 keyword=23)`` is now valid syntax.)
1825
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001826- ctypes function pointers that are COM methods have a boolean True
1827 value again.
1828
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001829- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1830 by denying s# to parse objects that have a releasebuffer procedure,
1831 and introducing s*.
1832
Georg Brandl1e13ea92008-08-11 09:07:59 +00001833- Issue #3537: Fix an assertion failure when an empty but presized dict
1834 object was stored in the freelist.
1835
Mark Dickinsonb6467572008-08-04 21:30:09 +00001836- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1837 ValueError consistently across platforms.
1838
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001839- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1840 (64bit Unix, for example), unichr() would truncate its argument and return
1841 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1842
Neal Norwitze7d8be82008-07-31 17:17:14 +00001843- Apply security patches from Apple.
1844
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001845- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1846 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1847
Antoine Pitrou92f82162008-07-25 22:22:08 +00001848- Issue #1819: function calls with several named parameters are now on
1849 average 35% faster (as measured by pybench).
1850
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001851- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1852 the python debugger steps into a class statement: the free variables (local
1853 variables defined in an outer scope) would be deleted from the outer scope.
1854
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001855- Issue #2620: Overflow checking when allocating or reallocating memory
1856 was not always being done properly in some python types and extension
1857 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1858 all been updated to perform better checks and places in the code that
1859 would previously leak memory on the error path when such an allocation
1860 failed have been fixed.

1866
Benjamin Petersone977ad42008-08-20 01:42:01 +00001867- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1868 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1869
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001870- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1871 version reported by these tools does not necessarily follow the python
1872 version numbering scheme, so the module is less strict when parsing it.
1873
Nick Coghlanf70385a2008-08-18 12:42:46 +00001874- Issue #2235: Added Py3k warnings for types which will become unhashable
1875 under the stricter __hash__ inheritance rules in 3.0. Several types

2007-----------------
2008
Georg Brandl3e483f62008-07-16 22:57:41 +00002009- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2010 its methods now allow for items objects that can be converted to
2011 an integer using operator.index().
2012
Mark Dickinson64b7e502008-07-16 09:40:03 +00002013- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2014 produced a ValueError instead of giving the correct float.
2015
Eric Smitha5fa5a22008-07-16 00:11:49 +00002016- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2017 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2018
Mark Dickinson7103aa42008-07-15 19:08:33 +00002019- Issue #3008: the float type has a new instance method 'float.hex'
2020 and a new class method 'float.fromhex' to convert floating-point
2021 numbers to and from hexadecimal strings, respectively.
2022
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002023- Issue #2235: __hash__ is once again inherited by default. To allow
2024 collections.Hashable to remain meaningful in the presence of the
2025 default hash implementation (object.__hash__), it is now possible
2026 to explicit block inheritance of hash by setting __hash__=None at
2027 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2028 level.
2029
Nick Coghlanb028f502008-07-13 14:52:36 +00002030- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2031 the parent module cannot be found while performing an absolute import.
2032 This means that an incorrectly defined __package__ attribute will
2033 now only prevent relative imports in that module rather than causing
2034 all imports from that module to fail.
2035
Nick Coghlan14ff9942008-07-08 14:21:42 +00002036- Issue #2517: Allow unicode messages in Exceptions again by correctly

2046 another thread's dictionary.
2047
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002048- Issue #3004: Minor change to slice.indices(): the start and stop
2049 arguments are now treated identically, making the behaviour easier
2050 to describe and understand. For example, slice(None, -10,
2051 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2052 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2053 10, -1).
2054
Georg Brandl278fc502008-07-19 12:46:12 +00002055- Issue #3219: Calling a function with repeated keyword arguments,
2056 f(a=2, a=23), would not cause a syntax error. This was a regression
2057 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002059- Issue #2862: Make int and float freelist management consistent with
2060 other freelists. Changes their CompactFreeList apis into

2067 api functions without holding the GIL, which could lead to a fatal
2068 error when they failed.
2069
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002070- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002095- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2096 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002097 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002098 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002505- On MacOS X it is now possible to install the framework in 64-bit
2506 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002507 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002508
2509 This is controlled by the configure argument ``--with-universal-archs``:
2510
2511 - ``--with-universal-archs=all``: install 4-way universal
2512
2513 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2514
2515 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2516
2517 This option should be used in combination with ``--enable-universalsdk=``.
2518
2519 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 +00002569- Issue #1631171: Re-implement the 'warnings' module in C (the
2570 original Python code has been kept as backup). This will allow for
2571 using the 'warning's machinery in such places as the parser where
2572 use of pure Python code is not possible. Both the ``showarning()``
2573 and ``formatwarning()`` gain an optional 'line' argument which is
2574 not called by default for backwards-compatibility reasons. Setting
2575 ``warnings.showwarning()`` to an implementation that lacks support
2576 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002639- Issue #2550: The approach used by client/server code for obtaining
2640 ports to listen on in network-oriented tests has been refined in an
2641 effort to facilitate running multiple instances of the entire
2642 regression test suite in parallel without issue.
2643 test_support.bind_port() has been fixed such that it will always
2644 return a unique port -- which wasn't always the case with the
2645 previous implementation, especially if socket options had been set
2646 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2647 new implementation of bind_port() will actually raise an exception
2648 if it is passed an AF_INET/SOCK_STREAM socket with either the
2649 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2650 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2651 the socket it's been passed. This currently only applies to
2652 Windows. This option prevents any other sockets from binding to the
2653 host/port we've bound to, thus removing the possibility of the
2654 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2655 when a second SOCK_STREAM socket binds and accepts to a host/port
2656 that's already been bound by another socket. The optional preferred
2657 port parameter to bind_port() has been removed. Under no
2658 circumstances should tests be hard coding ports!
2659
2660 test_support.find_unused_port() has also been introduced, which will
2661 pass a temporary socket object to bind_port() in order to obtain an
2662 unused port. The temporary socket object is then closed and
2663 deleted, and the port is returned. This method should only be used
2664 for obtaining an unused port in order to pass to an external program
2665 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2666 a parameter to a server-oriented class that doesn't give you direct
2667 access to the underlying socket used.
2668
2669 Finally, test_support.HOST has been introduced, which should be used
2670 for the host argument of any relevant socket calls (i.e. bind and
2671 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002672
2673 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002674 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002675 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2676 test_asynchat and test_socket_ssl.
2677
Georg Brandl3ee81df2008-05-17 18:14:43 +00002678 It is now possible for multiple instances of the regression test
2679 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002733- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002734 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2735 Plane. This affected raw unicode literals and the
2736 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2737 this case, like normal unicode literals and the 'unicode-escape'
2738 codec.

2947
Fred Drakea8ee94b2008-03-01 02:45:07 +00002948- Issue #2051: pyc and pyo files are no longer created with permission

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002955- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002956 issue 215555 for a discussion.
2957
Eric Smitha73fbe72008-02-23 03:09:44 +00002958- Added the future_builtins module, which contains hex() and oct().
2959 These are the PEP 3127 version of these functions, designed to be
2960 compatible with the hex() and oct() builtins from Python 3.0. They
2961 differ slightly in their output formats from the existing, unchanged
2962 Python 2.6 builtins. The expected usage of the future_builtins
2963 module is:
2964 from future_builtins import hex, oct
2965
Eric Smith7ef40bf2008-02-20 23:34:22 +00002966- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2967 exponents for exponents with absolute value < 100. Follows C99
2968 standard. This is a change on Windows, which would use 3 digits.
2969 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2970 so that any alterations it does to the resulting string will be
2971 available in stringlib/formatter.h (for float.__format__).
2972
Eric Smith5a3c1352008-02-19 13:21:56 +00002973- Implemented PEP 3101, Advanced String Formatting. This adds a new
2974 builtin format(); a format() method for str and unicode; a
2975 __format__() method to object, str, unicode, int, long, float, and
2976 datetime; the class string.Formatter; and the C API
2977 PyObject_Format().
2978
Georg Brandl3ee81df2008-05-17 18:14:43 +00002979- Fixed several potential crashes, all caused by specially crafted
2980 __del__ methods exploiting objects in temporarily inconsistent
2981 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002982
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002983- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002984 prevent a possible crash: an Abstract Base Class would try to access
2985 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002986

Georg Brandl3ee81df2008-05-17 18:14:43 +00003024- Patch #1473257: generator objects gain a gi_code attribute. This is
3025 the same object as the func_code attribute of the function that
3026 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003027
Georg Brandl3ee81df2008-05-17 18:14:43 +00003028- Issue #1920: "while 0" statements were completely removed by the
3029 compiler, even in the presence of an "else" clause, which is
3030 supposed to be run when the condition is false. Now the compiler
3031 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003032
Guido van Rossumeead05f2008-01-24 18:21:02 +00003033- A few crashers fixed: weakref_in_del.py (issue #1377858);

3040
Georg Brandl3ee81df2008-05-17 18:14:43 +00003041- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003042 several extension methods and modules do not work without unicode
3043 support.
3044

3049
Georg Brandl6caad7d2008-01-26 14:19:22 +00003050- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003051 added.
3052
Christian Heimesc94e2b52008-01-14 04:13:37 +00003053- sys.float_info / PyFloat_GetInfo: The floating point information
3054 object was converted from a dict to a specialized structseq object.
3055
Georg Brandl3ee81df2008-05-17 18:14:43 +00003056- Patch #1816: Added sys.flags structseq. It exposes the status of
3057 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003058
Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Objects/structseq.c: Implemented new structseq representation. The
3060 patch makes structseqs (e.g. the return value of os.stat) more
3061 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003062
Georg Brandl3ee81df2008-05-17 18:14:43 +00003063- Patch #1700288: added a type attribute cache that caches method
3064 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003065
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003066- Bug #1776: __import__() no longer accepts filenames on any platform.

3072 envvar and sys.dont_write_bytecode attribute. All these can be set
3073 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003074
Georg Brandl3ee81df2008-05-17 18:14:43 +00003075- Improve some exception messages when Windows fails to load an
3076 extension module. Now we get for example '%1 is not a valid Win32
3077 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003084- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003085 and INF. float("nan"), float("inf") and float("-inf") now work on
3086 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003087
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088- Compiler now generates simpler and faster code for dictionary

3134
Georg Brandl5a7eca12010-03-21 19:29:04 +00003135- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3137 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003138
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Issue #1686386: Tuple's tp_repr did not take into account the
3140 possibility of having a self-referential tuple, which is possible
3141 from C code. Nor did object's tp_str consider that a type's tp_str
3142 could do something that could lead to an inifinite recursion.
3143 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3144 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003145

3147 'print' statement to write to a file since the GIL was not released
3148 as needed. Now PyObject_Print() does the right thing along with
3149 various tp_print implementations of the built-in types and those in
3150 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003151

Georg Brandl3ee81df2008-05-17 18:14:43 +00003160 PyObject_Call() never calling back out to Python code to trigger
3161 recursion depth updates/checks. Required the creation of a static
3162 RuntimeError instance in case normalizing an exception put the
3163 recursion check value past its limit. Fixes crashers

Guido van Rossum143b5642007-03-23 04:58:42 +00003212- Bug #1683368: The object.__init__() and object.__new__() methods are
3213 now stricter in rejecting excess arguments. The only time when
3214 either allows excess arguments is when it is not overridden and the
3215 other one is. For backwards compatibility, when both are
3216 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003217 warning later). Also, type.__init__() insists on the same signature
3218 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003220- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3221 object to complex using its __complex__() method before falling back
3222 to the __float__() method. Therefore, the functions in the cmath
3223 module now can operate on objects that define a __complex__()
3224 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003242- Bug #1678647: write a newline after printing an exception in any
3243 case, even when converting the value to a string failed.
3244
Georg Brandl871f1bc2007-03-12 13:17:36 +00003245- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003246 its argument, if it exists. If not, it will work like before. This
3247 allows customizing the output of dir() in the presence of a
3248 __getattr__().

3258 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003259
Georg Brandlaa2321b2007-03-07 00:40:28 +00003260- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003261 makes the filenames the warning module prints much more sensible
3262 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003275- Patch #1674228: when assigning a slice (old-style), check for the
3276 sq_ass_slice instead of the sq_slice slot.
3277
Georg Brandl3ee81df2008-05-17 18:14:43 +00003278- When printing an unraisable error, don't print exceptions. before
3279 the name. This duplicates the behavior whening normally printing
3280 exceptions.

Georg Brandl2c1375c2006-10-12 11:27:59 +00003330- Bug #1545497: when given an explicit base, int() did ignore NULs
3331 embedded in the string to convert.
3332
Georg Brandl846f73a2006-10-08 07:11:54 +00003333- Bug #1569998: break inside a try statement (outside a loop) is now

Neal Norwitzdac090d2006-09-05 03:53:08 +00003380- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00003381 generator expressions (x for x, in ... ) works again. Fixing this
3382 problem required changing the .pyc magic number. This means that
3383 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003813 AttributeError instead of an IOError when the server's response

3905 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004186- The implementation of UnicodeError objects has been simplified
4187 (start and end attributes are now stored directly as Py_ssize_t
4188 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4191 with RFC 3207 and forgets any knowledge obtained from the server not
4192 obtained from the TLS negotiation itself. Patch contributed by Bill
4193 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004194
Georg Brandl3ee81df2008-05-17 18:14:43 +00004195- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004196 that the SMTP.starttls() caller no longer needs to call ehlo()
4197 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198 does not claim to support starttls. Adds the
4199 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4200 Fenner.

4280 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4281 silently miscode subclasses of those types. Now, it raises a
4282 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004283

Georg Brandl3ee81df2008-05-17 18:14:43 +00004298 time so that opening a database previously created with the DB_DUP
4299 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4300 opens. Specifically: dictionary assignment to a DB object will
4301 replace all values for a given key when the database allows
4302 duplicate values. DB users should use DB.put(k, v) when they want
4303 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004304

4310 characters with ASCII value less than 32. Also, it correctly quotes
4311 dots only if they occur on a single line, as opposed to the previous
4312 behavior of quoting dots if they are the second character of any
4313 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004314

4343 negative numbers, per the underlying C implementation.
Guido van Rossumbb2cc692007-01-14 17:03:32 +00004344

Georg Brandl3ee81df2008-05-17 18:14:43 +00004719- Removed the macfs module. It had been deprecated since Python 2.5.
4720 This lead to the deprecation of macostools.touched() as it relied
4721 solely on macfs and was a no-op under OS X.
