82 Decimal operation raises multiple signals and more than one of those

Antoine Pitrou53d7d062010-04-25 21:55:45 +0000118- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
119 where the method could block indefinitely if called just before the
120 event loop started running. This also fixes the occasional freezes
121 witnessed in test_httpservers.

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

1427What's New in Python 2.6.1
1428==========================
1429
1430*Release date: 04-Dec-2008*
1431
1432Core and Builtins
1433-----------------
1434
1435- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1436 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1437 instead of throwing a MemoryError.
1438
1439- Issue #4367: Python would segfault during compiling when the unicodedata
1440 module couldn't be imported and \N escapes were present.
1441
1442- Issue #4348: Some bytearray methods returned that didn't cause any change to
1443 the bytearray, returned the same bytearray instead of a copy.
1444
1445- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1446
1447- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1448
1449- Issue #4048: The parser module now correctly validates relative imports.
1450
1451- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1452 exec statement.
1453
1454- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1455 method does not return iterators for the 4th and 5th items.
1456
1457- Issue #4209: Enabling unicode_literals and the print_function in the same
1458 __future__ import didn't work.
1459
1460- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1461 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1462 really executed because I cannot move to such directory on win2k)
1463
1464- Issue #4069: When set.remove(element) is used with a set element, the element
1465 is temporarily replaced with an equivalent frozenset. But the eventual
1466 KeyError would always report the empty frozenset([]) as the missing key. Now
1467 it correctly refers to the initial element.
1468
1469- Fixed C99 style comments in several files. Python is now C89 compatible
1470 again.

1597- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1598 AttributeError instead of RuntimeError, depending in which C API call
1599 exactly the recursion limit is exceeded. Consequently, both exception types
1600 are caught and silenced.

1616
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001617- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1618
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001619- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1620 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1621 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1622 ``printf`` function, whereas PyString_FromFormat has an independent
1623 implementation and uses "%zd" on all platforms for size_t values.
1624 This makes a difference on win64, where ``printf`` needs "%Id" to display
1625 64bit values.
1626
Benjamin Peterson97179b02008-09-09 20:55:01 +00001627- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1628 error.
1629
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001630- Issue #3777: long() applied to a float object now always return a long
1631 object; previously an int would be returned for small values. the __long__
1632 method is allowed to return either an int or a long, but the behaviour of
1633 float objects should not change to respect backward compatibility.
1634
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001635- Issue #3751: str.rpartition would perform a left-partition when called with
1636 a unicode argument.
1637
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001638- Issue #3683: Fix compilation when --without-threads is given.
1639
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001640- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001641 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001642 was correctly parsed but parsing of subsequent arguments failed.
1643
Vinay Sajip35e3b032008-09-01 14:33:59 +00001644- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001645 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1646 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1647 when given a tuple of classes as second argument, were looking up
1648 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1649 type object.
1650
Neal Norwitz18aa3882008-08-24 05:04:52 +00001651- Fix crashes on memory allocation failure found with failmalloc.
1652
1653- Fix memory leaks found with valgrind and update suppressions file.
1654
1655- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1656
1657- Fix problem using wrong name in decimal module reported by pychecker.
1658
Christian Heimes7d4c3172008-08-22 19:47:25 +00001659- Silenced another compiler warning about a used but not defined
1660 function 'stringlib_contains_obj'.

1663 ``__delslice__``.
1664
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001665- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1666 library targets in the Makefile.
1667
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001668- Issue #1204: The configure script now tests for additional libraries
1669 that may be required when linking against readline. This fixes issues
1670 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001687- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1688 silent misbehaviour when a single instance is nested in multiple
1689 with statements, or when the methods are invoked in the wrong order.
1690
Vinay Sajip844f7412008-09-09 13:42:08 +00001691- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1692
Nick Coghland2e09382008-09-11 12:11:06 +00001693- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001694 return a list or None rather than a custom object.
1695
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001696- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1720 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1721 for catch_warnings() also led to an improvement in the raising of a
1722 DeprecationWarning related to warnings.warn_explicit().
1723
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001724- The deprecation warnings for the old camelCase threading API were removed.

1791-----------------
1792
Guido van Rossumf8402962008-08-20 15:01:50 +00001793- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1794 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1795 extensions do not automatically benefit from the class attribute
1796 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1797 to their tp_flags field if they care. This is a backwards
1798 compatibility feature; in 3.0, all types will use the cache by
1799 default.
1800
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001801- Keyword arguments can now follow starred arguments. (``f(a, *args,
1802 keyword=23)`` is now valid syntax.)
1803
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001804- ctypes function pointers that are COM methods have a boolean True
1805 value again.
1806
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001807- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1808 by denying s# to parse objects that have a releasebuffer procedure,
1809 and introducing s*.
1810
Georg Brandl1e13ea92008-08-11 09:07:59 +00001811- Issue #3537: Fix an assertion failure when an empty but presized dict
1812 object was stored in the freelist.
1813
Mark Dickinsonb6467572008-08-04 21:30:09 +00001814- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1815 ValueError consistently across platforms.
1816
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001817- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1818 (64bit Unix, for example), unichr() would truncate its argument and return
1819 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1820
Neal Norwitze7d8be82008-07-31 17:17:14 +00001821- Apply security patches from Apple.
1822
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001823- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1824 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1825
Antoine Pitrou92f82162008-07-25 22:22:08 +00001826- Issue #1819: function calls with several named parameters are now on
1827 average 35% faster (as measured by pybench).
1828
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001829- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1830 the python debugger steps into a class statement: the free variables (local
1831 variables defined in an outer scope) would be deleted from the outer scope.
1832
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001833- Issue #2620: Overflow checking when allocating or reallocating memory
1834 was not always being done properly in some python types and extension
1835 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1836 all been updated to perform better checks and places in the code that
1837 would previously leak memory on the error path when such an allocation
1838 failed have been fixed.

1844
Benjamin Petersone977ad42008-08-20 01:42:01 +00001845- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1846 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1847
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001848- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1849 version reported by these tools does not necessarily follow the python
1850 version numbering scheme, so the module is less strict when parsing it.
1851
Nick Coghlanf70385a2008-08-18 12:42:46 +00001852- Issue #2235: Added Py3k warnings for types which will become unhashable
1853 under the stricter __hash__ inheritance rules in 3.0. Several types
1854 which did not meet the rules for hash invariants and were already
1855 unhashable in 3.0 have now been explicitly flagged as unhashable in
1856 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1857 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1858
Brett Cannon88f801d2008-08-18 00:46:22 +00001859- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1860 imported into the module but exposed as part of the module's API.
1861
Brett Cannon7b96f072008-08-18 00:41:11 +00001862- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001866- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1867
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001868- Issue #3575: Incremental decoder's decode function now takes bytearray

1986
Georg Brandl3e483f62008-07-16 22:57:41 +00001987- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1988 its methods now allow for items objects that can be converted to
1989 an integer using operator.index().
1990
Mark Dickinson64b7e502008-07-16 09:40:03 +00001991- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1992 produced a ValueError instead of giving the correct float.
1993
Eric Smitha5fa5a22008-07-16 00:11:49 +00001994- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1995 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.

Mark Dickinson7103aa42008-07-15 19:08:33 +00001997- Issue #3008: the float type has a new instance method 'float.hex'
1998 and a new class method 'float.fromhex' to convert floating-point
1999 numbers to and from hexadecimal strings, respectively.
2000
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002001- Issue #2235: __hash__ is once again inherited by default. To allow
2002 collections.Hashable to remain meaningful in the presence of the
2003 default hash implementation (object.__hash__), it is now possible
2004 to explicit block inheritance of hash by setting __hash__=None at
2005 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2006 level.
2007

2009 the parent module cannot be found while performing an absolute import.
2010 This means that an incorrectly defined __package__ attribute will
2011 now only prevent relative imports in that module rather than causing
2012 all imports from that module to fail.
2013
Nick Coghlan14ff9942008-07-08 14:21:42 +00002014- Issue #2517: Allow unicode messages in Exceptions again by correctly

2025
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002026- Issue #3004: Minor change to slice.indices(): the start and stop
2027 arguments are now treated identically, making the behaviour easier
2028 to describe and understand. For example, slice(None, -10,
2029 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2030 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2031 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00002033- Issue #3219: Calling a function with repeated keyword arguments,

2074 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002075 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00002485 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002486
2487 This is controlled by the configure argument ``--with-universal-archs``:
2488
2489 - ``--with-universal-archs=all``: install 4-way universal
2490
2491 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2492
2493 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2494
2495 This option should be used in combination with ``--enable-universalsdk=``.

2548 original Python code has been kept as backup). This will allow for
2549 using the 'warning's machinery in such places as the parser where
2550 use of pure Python code is not possible. Both the ``showarning()``
2551 and ``formatwarning()`` gain an optional 'line' argument which is
2552 not called by default for backwards-compatibility reasons. Setting
2553 ``warnings.showwarning()`` to an implementation that lacks support
2554 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002617- Issue #2550: The approach used by client/server code for obtaining
2618 ports to listen on in network-oriented tests has been refined in an
2619 effort to facilitate running multiple instances of the entire
2620 regression test suite in parallel without issue.
2621 test_support.bind_port() has been fixed such that it will always
2622 return a unique port -- which wasn't always the case with the
2623 previous implementation, especially if socket options had been set
2624 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2625 new implementation of bind_port() will actually raise an exception
2626 if it is passed an AF_INET/SOCK_STREAM socket with either the
2627 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2628 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2629 the socket it's been passed. This currently only applies to
2630 Windows. This option prevents any other sockets from binding to the
2631 host/port we've bound to, thus removing the possibility of the
2632 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2633 when a second SOCK_STREAM socket binds and accepts to a host/port
2634 that's already been bound by another socket. The optional preferred
2635 port parameter to bind_port() has been removed. Under no
2636 circumstances should tests be hard coding ports!
2637
2638 test_support.find_unused_port() has also been introduced, which will
2639 pass a temporary socket object to bind_port() in order to obtain an
2640 unused port. The temporary socket object is then closed and
2641 deleted, and the port is returned. This method should only be used
2642 for obtaining an unused port in order to pass to an external program
2643 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2644 a parameter to a server-oriented class that doesn't give you direct
2645 access to the underlying socket used.
2646
2647 Finally, test_support.HOST has been introduced, which should be used
2648 for the host argument of any relevant socket calls (i.e. bind and
2649 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002650
2651 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002652 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002653 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2654 test_asynchat and test_socket_ssl.
2655
Georg Brandl3ee81df2008-05-17 18:14:43 +00002656 It is now possible for multiple instances of the regression test
2657 suite to run in parallel without issue.

2714 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2715 this case, like normal unicode literals and the 'unicode-escape'
2716 codec.

2923Core and builtins
2924-----------------
2925
Fred Drakea8ee94b2008-03-01 02:45:07 +00002926- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002927 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002932
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002933- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002934 issue 215555 for a discussion.
2935
Eric Smitha73fbe72008-02-23 03:09:44 +00002936- Added the future_builtins module, which contains hex() and oct().
2937 These are the PEP 3127 version of these functions, designed to be
2938 compatible with the hex() and oct() builtins from Python 3.0. They
2939 differ slightly in their output formats from the existing, unchanged
2940 Python 2.6 builtins. The expected usage of the future_builtins
2941 module is:
2942 from future_builtins import hex, oct
2943
Eric Smith7ef40bf2008-02-20 23:34:22 +00002944- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2945 exponents for exponents with absolute value < 100. Follows C99
2946 standard. This is a change on Windows, which would use 3 digits.
2947 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2948 so that any alterations it does to the resulting string will be
2949 available in stringlib/formatter.h (for float.__format__).
2950
Eric Smith5a3c1352008-02-19 13:21:56 +00002951- Implemented PEP 3101, Advanced String Formatting. This adds a new
2952 builtin format(); a format() method for str and unicode; a
2953 __format__() method to object, str, unicode, int, long, float, and
2954 datetime; the class string.Formatter; and the C API
2955 PyObject_Format().
2956
Georg Brandl3ee81df2008-05-17 18:14:43 +00002957- Fixed several potential crashes, all caused by specially crafted
2958 __del__ methods exploiting objects in temporarily inconsistent
2959 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002960
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002961- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002962 prevent a possible crash: an Abstract Base Class would try to access
2963 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002965- Fixed repr() and str() of complex numbers with infinity or nan as
2966 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002967
Georg Brandl3ee81df2008-05-17 18:14:43 +00002968- Clear all free lists during a gc.collect() of the highest generation
2969 in order to allow pymalloc to free more arenas. Python may give back
2970 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002971
Georg Brandl3ee81df2008-05-17 18:14:43 +00002972- Issue #2045: Fix an infinite recursion triggered when printing a
2973 subclass of collections.defaultdict, if its default_factory is set
2974 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002975
Christian Heimesf75dbef2008-02-08 00:11:31 +00002976- Fixed a minor memory leak in dictobject.c. The content of the free
2977 list was not freed on interpreter shutdown.
2978
Georg Brandl5a7eca12010-03-21 19:29:04 +00002979- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003002- Patch #1473257: generator objects gain a gi_code attribute. This is
3003 the same object as the func_code attribute of the function that
3004 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003005
Georg Brandl3ee81df2008-05-17 18:14:43 +00003006- Issue #1920: "while 0" statements were completely removed by the
3007 compiler, even in the presence of an "else" clause, which is
3008 supposed to be run when the condition is false. Now the compiler
3009 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003010
Guido van Rossumeead05f2008-01-24 18:21:02 +00003011- A few crashers fixed: weakref_in_del.py (issue #1377858);
3012 loosing_dict_ref.py (issue #1303614, test67.py);
3013 borrowed_ref_[34].py (not in tracker).
3014
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003015- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003016 suppressed while an extension is loaded by calling SetErrorMode in

3018
Georg Brandl3ee81df2008-05-17 18:14:43 +00003019- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003020 several extension methods and modules do not work without unicode
3021 support.
3022
Georg Brandl26543b12008-01-21 18:36:51 +00003023- Issue #1882: when compiling code from a string, encoding cookies in the

3027
Georg Brandl6caad7d2008-01-26 14:19:22 +00003028- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003029 added.
3030
Christian Heimesc94e2b52008-01-14 04:13:37 +00003031- sys.float_info / PyFloat_GetInfo: The floating point information
3032 object was converted from a dict to a specialized structseq object.
3033
Georg Brandl3ee81df2008-05-17 18:14:43 +00003034- Patch #1816: Added sys.flags structseq. It exposes the status of
3035 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003036
Georg Brandl3ee81df2008-05-17 18:14:43 +00003037- Objects/structseq.c: Implemented new structseq representation. The
3038 patch makes structseqs (e.g. the return value of os.stat) more
3039 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003040
Georg Brandl3ee81df2008-05-17 18:14:43 +00003041- Patch #1700288: added a type attribute cache that caches method
3042 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003043
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003044- Bug #1776: __import__() no longer accepts filenames on any platform.
3045 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003046
Georg Brandlaed6c662008-01-07 17:25:53 +00003047- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3048
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3050 envvar and sys.dont_write_bytecode attribute. All these can be set
3051 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003052
Georg Brandl3ee81df2008-05-17 18:14:43 +00003053- Improve some exception messages when Windows fails to load an
3054 extension module. Now we get for example '%1 is not a valid Win32
3055 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003062- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003063 and INF. float("nan"), float("inf") and float("-inf") now work on
3064 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003065
Georg Brandl3ee81df2008-05-17 18:14:43 +00003066- Compiler now generates simpler and faster code for dictionary
3067 literals. The oparg for BUILD_MAP now indicates an estimated
3068 dictionary size. There is a new opcode, STORE_MAP, for adding
3069 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- Issue #1265: Fix a problem with sys.settrace, if the tracing
3104 function uses a generator expression when at the same time the
3105 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003106
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003107- sets and frozensets now have an isdisjoint() method.
3108
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003109- optimize the performance of builtin.sum().

3112
Georg Brandl5a7eca12010-03-21 19:29:04 +00003113- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003114 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3115 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003116
Georg Brandl3ee81df2008-05-17 18:14:43 +00003117- Issue #1686386: Tuple's tp_repr did not take into account the
3118 possibility of having a self-referential tuple, which is possible
3119 from C code. Nor did object's tp_str consider that a type's tp_str
3120 could do something that could lead to an inifinite recursion.
3121 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3122 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003123
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124- Issue #1164: It was possible to trigger deadlock when using the
3125 'print' statement to write to a file since the GIL was not released
3126 as needed. Now PyObject_Print() does the right thing along with
3127 various tp_print implementations of the built-in types and those in
3128 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003129
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00003136
Brett Cannon1e534b52007-09-07 04:18:30 +00003137- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003138 PyObject_Call() never calling back out to Python code to trigger
3139 recursion depth updates/checks. Required the creation of a static
3140 RuntimeError instance in case normalizing an exception put the
3141 recursion check value past its limit. Fixes crashers
3142 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003143

Neal Norwitz0ac60192007-05-27 04:08:54 +00003157- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003158 __*__ attributes. (Some already existed, e.g., __doc__ and
3159 __name__.)

3163
Georg Brandl2134e752007-05-21 20:34:16 +00003164- Patch #1686487: you can now pass any mapping after '**' in function
3165 calls.
3166
Collin Winter62903052007-05-18 23:11:24 +00003167- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003168 "except E as target:". This is to provide forwards compatibility
3169 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003173- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003174 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003176- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003177 setting a plain string, ie don't expand to single letter identifiers.
3178
Raymond Hettinger13936692007-04-11 18:40:58 +00003179- Request #1191699: Slices can now be pickled.
3180
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003181- Request #1193128: str.translate() now allows a None argument for
3182 translations that only remove characters without re-mapping the
3183 remaining characters.
3184
Georg Brandl5cb76c12007-03-21 09:00:39 +00003185- Patch #1682205: a TypeError while unpacking an iterable is no longer
3186 masked by a generic one with the message "unpack non-sequence".
3187
Neal Norwitzaa754b72007-03-21 06:39:48 +00003188- Remove unused file Python/fmod.c.
3189
Guido van Rossum143b5642007-03-23 04:58:42 +00003190- Bug #1683368: The object.__init__() and object.__new__() methods are
3191 now stricter in rejecting excess arguments. The only time when
3192 either allows excess arguments is when it is not overridden and the
3193 other one is. For backwards compatibility, when both are
3194 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003195 warning later). Also, type.__init__() insists on the same signature
3196 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003197
Georg Brandl3ee81df2008-05-17 18:14:43 +00003198- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3199 object to complex using its __complex__() method before falling back
3200 to the __float__() method. Therefore, the functions in the cmath

Georg Brandl3ee81df2008-05-17 18:14:43 +00003224 its argument, if it exists. If not, it will work like before. This
3225 allows customizing the output of dir() in the presence of a
3226 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003238- Patch #703779: unset __file__ in __main__ after running a file. This

3267 created a weakref on itself during a __del__ call for new-style
3268 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00003308- Bug #1545497: when given an explicit base, int() did ignore NULs
3309 embedded in the string to convert.
3310
Georg Brandl846f73a2006-10-08 07:11:54 +00003311- Bug #1569998: break inside a try statement (outside a loop) is now
3312 recognized and rejected.

Georg Brandl4e933132006-09-06 20:05:58 +00003341- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003359 generator expressions (x for x, in ... ) works again. Fixing this
3360 problem required changing the .pyc magic number. This means that
3361 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00003400- Removed uses of dict.has_key() from distutils, and uses of
3401 callable() from copy_reg.py, so the interpreter now starts up

Georg Brandl3ee81df2008-05-17 18:14:43 +00004173- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004174 that the SMTP.starttls() caller no longer needs to call ehlo()
4175 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004176 does not claim to support starttls. Adds the
4177 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4258 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4259 silently miscode subclasses of those types. Now, it raises a
4260 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004261

Georg Brandl3ee81df2008-05-17 18:14:43 +00004276 time so that opening a database previously created with the DB_DUP
4277 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4278 opens. Specifically: dictionary assignment to a DB object will
4279 replace all values for a given key when the database allows
4280 duplicate values. DB users should use DB.put(k, v) when they want
4281 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004282

4288 characters with ASCII value less than 32. Also, it correctly quotes
4289 dots only if they occur on a single line, as opposed to the previous
4290 behavior of quoting dots if they are the second character of any
4291 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004292
