119
Antoine Pitrou53d7d062010-04-25 21:55:45 +0000120- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
121 where the method could block indefinitely if called just before the
122 event loop started running. This also fixes the occasional freezes
123 witnessed in test_httpservers.
124

138 a non-infinite timeout. Also make that method friendlier with applications

1267- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1268 302 conformant loader) will now work correctly in most cases (they
1269 are still subject to the constraints that exist for all code running

1429What's New in Python 2.6.1
1430==========================
1431
1432*Release date: 04-Dec-2008*
1433
1434Core and Builtins
1435-----------------
1436
1437- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1438 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1439 instead of throwing a MemoryError.
1440
1441- Issue #4367: Python would segfault during compiling when the unicodedata
1442 module couldn't be imported and \N escapes were present.
1443
1444- Issue #4348: Some bytearray methods returned that didn't cause any change to
1445 the bytearray, returned the same bytearray instead of a copy.
1446
1447- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1448
1449- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1450
1451- Issue #4048: The parser module now correctly validates relative imports.
1452
1453- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1454 exec statement.
1455
1456- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1457 method does not return iterators for the 4th and 5th items.
1458
1459- Issue #4209: Enabling unicode_literals and the print_function in the same
1460 __future__ import didn't work.
1461
1462- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1463 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1464 really executed because I cannot move to such directory on win2k)
1465
1466- Issue #4069: When set.remove(element) is used with a set element, the element
1467 is temporarily replaced with an equivalent frozenset. But the eventual
1468 KeyError would always report the empty frozenset([]) as the missing key. Now
1469 it correctly refers to the initial element.
1470
1471- Fixed C99 style comments in several files. Python is now C89 compatible
1472 again.

1599- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1600 AttributeError instead of RuntimeError, depending in which C API call
1601 exactly the recursion limit is exceeded. Consequently, both exception types
1602 are caught and silenced.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001619- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1620
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001621- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1622 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1623 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1624 ``printf`` function, whereas PyString_FromFormat has an independent
1625 implementation and uses "%zd" on all platforms for size_t values.
1626 This makes a difference on win64, where ``printf`` needs "%Id" to display
1627 64bit values.
1628
Benjamin Peterson97179b02008-09-09 20:55:01 +00001629- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1630 error.
1631
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001632- Issue #3777: long() applied to a float object now always return a long
1633 object; previously an int would be returned for small values. the __long__
1634 method is allowed to return either an int or a long, but the behaviour of
1635 float objects should not change to respect backward compatibility.
1636
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001637- Issue #3751: str.rpartition would perform a left-partition when called with
1638 a unicode argument.
1639
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001640- Issue #3683: Fix compilation when --without-threads is given.
1641
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001642- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001643 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001644 was correctly parsed but parsing of subsequent arguments failed.
1645
Vinay Sajip35e3b032008-09-01 14:33:59 +00001646- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001647 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1648 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1649 when given a tuple of classes as second argument, were looking up
1650 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1651 type object.
1652
Neal Norwitz18aa3882008-08-24 05:04:52 +00001653- Fix crashes on memory allocation failure found with failmalloc.
1654
1655- Fix memory leaks found with valgrind and update suppressions file.
1656
1657- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1658
1659- Fix problem using wrong name in decimal module reported by pychecker.
1660
Christian Heimes7d4c3172008-08-22 19:47:25 +00001661- Silenced another compiler warning about a used but not defined
1662 function 'stringlib_contains_obj'.

1665 ``__delslice__``.
1666
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001667- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1668 library targets in the Makefile.
1669
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001670- Issue #1204: The configure script now tests for additional libraries
1671 that may be required when linking against readline. This fixes issues
1672 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001689- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1690 silent misbehaviour when a single instance is nested in multiple
1691 with statements, or when the methods are invoked in the wrong order.
1692
Vinay Sajip844f7412008-09-09 13:42:08 +00001693- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1694
Nick Coghland2e09382008-09-11 12:11:06 +00001695- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001696 return a list or None rather than a custom object.
1697
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001698- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1722 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1723 for catch_warnings() also led to an improvement in the raising of a
1724 DeprecationWarning related to warnings.warn_explicit().
1725
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001726- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001791
1792Core and Builtins
1793-----------------
1794
Guido van Rossumf8402962008-08-20 15:01:50 +00001795- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1796 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1797 extensions do not automatically benefit from the class attribute
1798 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1799 to their tp_flags field if they care. This is a backwards
1800 compatibility feature; in 3.0, all types will use the cache by
1801 default.
1802
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001803- Keyword arguments can now follow starred arguments. (``f(a, *args,
1804 keyword=23)`` is now valid syntax.)
1805
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001806- ctypes function pointers that are COM methods have a boolean True
1807 value again.
1808
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001809- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1810 by denying s# to parse objects that have a releasebuffer procedure,
1811 and introducing s*.
1812
Georg Brandl1e13ea92008-08-11 09:07:59 +00001813- Issue #3537: Fix an assertion failure when an empty but presized dict
1814 object was stored in the freelist.
1815
Mark Dickinsonb6467572008-08-04 21:30:09 +00001816- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1817 ValueError consistently across platforms.
1818
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001819- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1820 (64bit Unix, for example), unichr() would truncate its argument and return
1821 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1822
Neal Norwitze7d8be82008-07-31 17:17:14 +00001823- Apply security patches from Apple.
1824
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001825- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1826 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1827
Antoine Pitrou92f82162008-07-25 22:22:08 +00001828- Issue #1819: function calls with several named parameters are now on
1829 average 35% faster (as measured by pybench).
1830
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001831- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1832 the python debugger steps into a class statement: the free variables (local
1833 variables defined in an outer scope) would be deleted from the outer scope.
1834
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001835- Issue #2620: Overflow checking when allocating or reallocating memory
1836 was not always being done properly in some python types and extension
1837 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1838 all been updated to perform better checks and places in the code that
1839 would previously leak memory on the error path when such an allocation
1840 failed have been fixed.

1846
Benjamin Petersone977ad42008-08-20 01:42:01 +00001847- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1848 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1849
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001850- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1851 version reported by these tools does not necessarily follow the python
1852 version numbering scheme, so the module is less strict when parsing it.
1853
Nick Coghlanf70385a2008-08-18 12:42:46 +00001854- Issue #2235: Added Py3k warnings for types which will become unhashable
1855 under the stricter __hash__ inheritance rules in 3.0. Several types
1856 which did not meet the rules for hash invariants and were already
1857 unhashable in 3.0 have now been explicitly flagged as unhashable in
1858 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1859 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1860
Brett Cannon88f801d2008-08-18 00:46:22 +00001861- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1862 imported into the module but exposed as part of the module's API.
1863
Brett Cannon7b96f072008-08-18 00:41:11 +00001864- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1865
Brett Cannon46225e72008-08-18 00:36:52 +00001866- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001868- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1869
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001870- Issue #3575: Incremental decoder's decode function now takes bytearray

1988
Georg Brandl3e483f62008-07-16 22:57:41 +00001989- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1990 its methods now allow for items objects that can be converted to
1991 an integer using operator.index().
1992
Mark Dickinson64b7e502008-07-16 09:40:03 +00001993- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1994 produced a ValueError instead of giving the correct float.
1995
Eric Smitha5fa5a22008-07-16 00:11:49 +00001996- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1997 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1998
Mark Dickinson7103aa42008-07-15 19:08:33 +00001999- Issue #3008: the float type has a new instance method 'float.hex'
2000 and a new class method 'float.fromhex' to convert floating-point
2001 numbers to and from hexadecimal strings, respectively.
2002
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002003- Issue #2235: __hash__ is once again inherited by default. To allow
2004 collections.Hashable to remain meaningful in the presence of the
2005 default hash implementation (object.__hash__), it is now possible
2006 to explicit block inheritance of hash by setting __hash__=None at
2007 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2008 level.
2009
Nick Coghlanb028f502008-07-13 14:52:36 +00002010- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2011 the parent module cannot be found while performing an absolute import.
2012 This means that an incorrectly defined __package__ attribute will
2013 now only prevent relative imports in that module rather than causing
2014 all imports from that module to fail.
2015
Nick Coghlan14ff9942008-07-08 14:21:42 +00002016- Issue #2517: Allow unicode messages in Exceptions again by correctly

2027
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002028- Issue #3004: Minor change to slice.indices(): the start and stop
2029 arguments are now treated identically, making the behaviour easier
2030 to describe and understand. For example, slice(None, -10,
2031 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2032 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2033 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00002035- Issue #3219: Calling a function with repeated keyword arguments,

2076 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002077 wrong because the actual transmitted size could differ from the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002488
2489 This is controlled by the configure argument ``--with-universal-archs``:
2490
2491 - ``--with-universal-archs=all``: install 4-way universal
2492
2493 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2494
2495 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2496
2497 This option should be used in combination with ``--enable-universalsdk=``.

2550 original Python code has been kept as backup). This will allow for
2551 using the 'warning's machinery in such places as the parser where
2552 use of pure Python code is not possible. Both the ``showarning()``
2553 and ``formatwarning()`` gain an optional 'line' argument which is
2554 not called by default for backwards-compatibility reasons. Setting
2555 ``warnings.showwarning()`` to an implementation that lacks support
2556 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002619- Issue #2550: The approach used by client/server code for obtaining
2620 ports to listen on in network-oriented tests has been refined in an
2621 effort to facilitate running multiple instances of the entire
2622 regression test suite in parallel without issue.
2623 test_support.bind_port() has been fixed such that it will always
2624 return a unique port -- which wasn't always the case with the
2625 previous implementation, especially if socket options had been set
2626 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2627 new implementation of bind_port() will actually raise an exception
2628 if it is passed an AF_INET/SOCK_STREAM socket with either the
2629 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2630 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2631 the socket it's been passed. This currently only applies to
2632 Windows. This option prevents any other sockets from binding to the
2633 host/port we've bound to, thus removing the possibility of the
2634 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2635 when a second SOCK_STREAM socket binds and accepts to a host/port
2636 that's already been bound by another socket. The optional preferred
2637 port parameter to bind_port() has been removed. Under no
2638 circumstances should tests be hard coding ports!
2639
2640 test_support.find_unused_port() has also been introduced, which will
2641 pass a temporary socket object to bind_port() in order to obtain an
2642 unused port. The temporary socket object is then closed and
2643 deleted, and the port is returned. This method should only be used
2644 for obtaining an unused port in order to pass to an external program
2645 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2646 a parameter to a server-oriented class that doesn't give you direct
2647 access to the underlying socket used.
2648
2649 Finally, test_support.HOST has been introduced, which should be used
2650 for the host argument of any relevant socket calls (i.e. bind and
2651 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002652
2653 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002654 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002655 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2656 test_asynchat and test_socket_ssl.
2657
Georg Brandl3ee81df2008-05-17 18:14:43 +00002658 It is now possible for multiple instances of the regression test
2659 suite to run in parallel without issue.

2716 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2717 this case, like normal unicode literals and the 'unicode-escape'
2718 codec.

2926-----------------
2927
Fred Drakea8ee94b2008-03-01 02:45:07 +00002928- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002929 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002934
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002935- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002936 issue 215555 for a discussion.
2937
Eric Smitha73fbe72008-02-23 03:09:44 +00002938- Added the future_builtins module, which contains hex() and oct().
2939 These are the PEP 3127 version of these functions, designed to be
2940 compatible with the hex() and oct() builtins from Python 3.0. They
2941 differ slightly in their output formats from the existing, unchanged
2942 Python 2.6 builtins. The expected usage of the future_builtins
2943 module is:
2944 from future_builtins import hex, oct
2945
Eric Smith7ef40bf2008-02-20 23:34:22 +00002946- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2947 exponents for exponents with absolute value < 100. Follows C99
2948 standard. This is a change on Windows, which would use 3 digits.
2949 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2950 so that any alterations it does to the resulting string will be
2951 available in stringlib/formatter.h (for float.__format__).
2952
Eric Smith5a3c1352008-02-19 13:21:56 +00002953- Implemented PEP 3101, Advanced String Formatting. This adds a new
2954 builtin format(); a format() method for str and unicode; a
2955 __format__() method to object, str, unicode, int, long, float, and
2956 datetime; the class string.Formatter; and the C API
2957 PyObject_Format().
2958
Georg Brandl3ee81df2008-05-17 18:14:43 +00002959- Fixed several potential crashes, all caused by specially crafted
2960 __del__ methods exploiting objects in temporarily inconsistent
2961 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002962
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002963- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002964 prevent a possible crash: an Abstract Base Class would try to access
2965 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002966
Georg Brandl3ee81df2008-05-17 18:14:43 +00002967- Fixed repr() and str() of complex numbers with infinity or nan as
2968 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002969
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970- Clear all free lists during a gc.collect() of the highest generation
2971 in order to allow pymalloc to free more arenas. Python may give back
2972 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002973
Georg Brandl3ee81df2008-05-17 18:14:43 +00002974- Issue #2045: Fix an infinite recursion triggered when printing a
2975 subclass of collections.defaultdict, if its default_factory is set
2976 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002977
Christian Heimesf75dbef2008-02-08 00:11:31 +00002978- Fixed a minor memory leak in dictobject.c. The content of the free
2979 list was not freed on interpreter shutdown.
2980
Georg Brandl5a7eca12010-03-21 19:29:04 +00002981- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002982 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002983

Georg Brandl3ee81df2008-05-17 18:14:43 +00003004- Patch #1473257: generator objects gain a gi_code attribute. This is
3005 the same object as the func_code attribute of the function that
3006 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003007
Georg Brandl3ee81df2008-05-17 18:14:43 +00003008- Issue #1920: "while 0" statements were completely removed by the
3009 compiler, even in the presence of an "else" clause, which is
3010 supposed to be run when the condition is false. Now the compiler
3011 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003012
Guido van Rossumeead05f2008-01-24 18:21:02 +00003013- A few crashers fixed: weakref_in_del.py (issue #1377858);
3014 loosing_dict_ref.py (issue #1303614, test67.py);
3015 borrowed_ref_[34].py (not in tracker).
3016
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003017- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003018 suppressed while an extension is loaded by calling SetErrorMode in
3019 dynload_win.c. The error is still reported properly.
3020
Georg Brandl3ee81df2008-05-17 18:14:43 +00003021- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003022 several extension methods and modules do not work without unicode
3023 support.
3024
Georg Brandl26543b12008-01-21 18:36:51 +00003025- Issue #1882: when compiling code from a string, encoding cookies in the

3029
Georg Brandl6caad7d2008-01-26 14:19:22 +00003030- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003031 added.
3032
Christian Heimesc94e2b52008-01-14 04:13:37 +00003033- sys.float_info / PyFloat_GetInfo: The floating point information
3034 object was converted from a dict to a specialized structseq object.
3035
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036- Patch #1816: Added sys.flags structseq. It exposes the status of
3037 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003038
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039- Objects/structseq.c: Implemented new structseq representation. The
3040 patch makes structseqs (e.g. the return value of os.stat) more
3041 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003042
Georg Brandl3ee81df2008-05-17 18:14:43 +00003043- Patch #1700288: added a type attribute cache that caches method
3044 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003045
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003046- Bug #1776: __import__() no longer accepts filenames on any platform.
3047 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003048
Georg Brandlaed6c662008-01-07 17:25:53 +00003049- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3050
Georg Brandl3ee81df2008-05-17 18:14:43 +00003051- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3052 envvar and sys.dont_write_bytecode attribute. All these can be set
3053 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003054
Georg Brandl3ee81df2008-05-17 18:14:43 +00003055- Improve some exception messages when Windows fails to load an
3056 extension module. Now we get for example '%1 is not a valid Win32
3057 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003058

Christian Heimes0a8143f2007-12-18 23:22:54 +00003064- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003065 and INF. float("nan"), float("inf") and float("-inf") now work on
3066 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003067
Georg Brandl3ee81df2008-05-17 18:14:43 +00003068- Compiler now generates simpler and faster code for dictionary
3069 literals. The oparg for BUILD_MAP now indicates an estimated
3070 dictionary size. There is a new opcode, STORE_MAP, for adding
3071 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003100- Patch #1739468: Directories and zipfiles containing a __main__.py
3101 file can now be directly executed by passing their name to the
3102 interpreter. The directory/zipfile is automatically inserted as the
3103 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003105- Issue #1265: Fix a problem with sys.settrace, if the tracing
3106 function uses a generator expression when at the same time the
3107 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003108
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003109- sets and frozensets now have an isdisjoint() method.
3110
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003111- optimize the performance of builtin.sum().
3112

3114
Georg Brandl5a7eca12010-03-21 19:29:04 +00003115- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3117 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003118
Georg Brandl3ee81df2008-05-17 18:14:43 +00003119- Issue #1686386: Tuple's tp_repr did not take into account the
3120 possibility of having a self-referential tuple, which is possible
3121 from C code. Nor did object's tp_str consider that a type's tp_str
3122 could do something that could lead to an inifinite recursion.
3123 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3124 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003125
Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Issue #1164: It was possible to trigger deadlock when using the
3127 'print' statement to write to a file since the GIL was not released
3128 as needed. Now PyObject_Print() does the right thing along with
3129 various tp_print implementations of the built-in types and those in
3130 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003131
Georg Brandl3ee81df2008-05-17 18:14:43 +00003132- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00003138
Brett Cannon1e534b52007-09-07 04:18:30 +00003139- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003140 PyObject_Call() never calling back out to Python code to trigger
3141 recursion depth updates/checks. Required the creation of a static
3142 RuntimeError instance in case normalizing an exception put the
3143 recursion check value past its limit. Fixes crashers
3144 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003145

Neal Norwitz0ac60192007-05-27 04:08:54 +00003159- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003160 __*__ attributes. (Some already existed, e.g., __doc__ and
3161 __name__.)

3165
Georg Brandl2134e752007-05-21 20:34:16 +00003166- Patch #1686487: you can now pass any mapping after '**' in function
3167 calls.
3168
Collin Winter62903052007-05-18 23:11:24 +00003169- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003170 "except E as target:". This is to provide forwards compatibility
3171 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003175- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003176 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003178- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003179 setting a plain string, ie don't expand to single letter identifiers.
3180
Raymond Hettinger13936692007-04-11 18:40:58 +00003181- Request #1191699: Slices can now be pickled.
3182
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003183- Request #1193128: str.translate() now allows a None argument for
3184 translations that only remove characters without re-mapping the
3185 remaining characters.
3186
Georg Brandl5cb76c12007-03-21 09:00:39 +00003187- Patch #1682205: a TypeError while unpacking an iterable is no longer
3188 masked by a generic one with the message "unpack non-sequence".
3189
Neal Norwitzaa754b72007-03-21 06:39:48 +00003190- Remove unused file Python/fmod.c.
3191
Guido van Rossum143b5642007-03-23 04:58:42 +00003192- Bug #1683368: The object.__init__() and object.__new__() methods are
3193 now stricter in rejecting excess arguments. The only time when
3194 either allows excess arguments is when it is not overridden and the
3195 other one is. For backwards compatibility, when both are
3196 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003197 warning later). Also, type.__init__() insists on the same signature
3198 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003199
Georg Brandl3ee81df2008-05-17 18:14:43 +00003200- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3201 object to complex using its __complex__() method before falling back
3202 to the __float__() method. Therefore, the functions in the cmath

Georg Brandl3ee81df2008-05-17 18:14:43 +00003226 its argument, if it exists. If not, it will work like before. This
3227 allows customizing the output of dir() in the presence of a
3228 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003240- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00003310- Bug #1545497: when given an explicit base, int() did ignore NULs
3311 embedded in the string to convert.
3312
Georg Brandl846f73a2006-10-08 07:11:54 +00003313- Bug #1569998: break inside a try statement (outside a loop) is now
3314 recognized and rejected.

Georg Brandl4e933132006-09-06 20:05:58 +00003343- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003361 generator expressions (x for x, in ... ) works again. Fixing this
3362 problem required changing the .pyc magic number. This means that
3363 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004175- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004176 that the SMTP.starttls() caller no longer needs to call ehlo()
4177 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178 does not claim to support starttls. Adds the
4179 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4260 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4261 silently miscode subclasses of those types. Now, it raises a
4262 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004263

Georg Brandl3ee81df2008-05-17 18:14:43 +00004278 time so that opening a database previously created with the DB_DUP
4279 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4280 opens. Specifically: dictionary assignment to a DB object will
4281 replace all values for a given key when the database allows
4282 duplicate values. DB users should use DB.put(k, v) when they want
4283 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004284

4290 characters with ASCII value less than 32. Also, it correctly quotes
4291 dots only if they occur on a single line, as opposed to the previous
4292 behavior of quoting dots if they are the second character of any
4293 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004294
