374 302 conformant loader) will now work correctly in most cases (they
375 are still subject to the constraints that exist for all code running

535What's New in Python 2.6.1
536==========================
537
538*Release date: 04-Dec-2008*
539
540Core and Builtins
541-----------------
542
543- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
544 interpreter to abort ("Fatal Python error: Could not reset the stack!")
545 instead of throwing a MemoryError.
546
547- Issue #4367: Python would segfault during compiling when the unicodedata
548 module couldn't be imported and \N escapes were present.
549
550- Issue #4348: Some bytearray methods returned that didn't cause any change to
551 the bytearray, returned the same bytearray instead of a copy.
552
553- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
554
555- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
556
557- Issue #4048: The parser module now correctly validates relative imports.
558
559- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
560 exec statement.
561
562- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
563 method does not return iterators for the 4th and 5th items.
564
565- Issue #4209: Enabling unicode_literals and the print_function in the same
566 __future__ import didn't work.
567
568- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
569 returned a path longer than MAX_PATH. (But It's doubtful this code path is
570 really executed because I cannot move to such directory on win2k)
571
572- Issue #4069: When set.remove(element) is used with a set element, the element
573 is temporarily replaced with an equivalent frozenset. But the eventual
574 KeyError would always report the empty frozenset([]) as the missing key. Now
575 it correctly refers to the initial element.
576
577- Fixed C99 style comments in several files. Python is now C89 compatible
578 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000725- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
726
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000727- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
728 PyString_FromFormat or PyErr_Format to display size_t values. The macro
729 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
730 ``printf`` function, whereas PyString_FromFormat has an independent
731 implementation and uses "%zd" on all platforms for size_t values.
732 This makes a difference on win64, where ``printf`` needs "%Id" to display
733 64bit values.
734
Benjamin Peterson97179b02008-09-09 20:55:01 +0000735- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
736 error.
737
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000738- Issue #3777: long() applied to a float object now always return a long
739 object; previously an int would be returned for small values. the __long__
740 method is allowed to return either an int or a long, but the behaviour of
741 float objects should not change to respect backward compatibility.
742
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000743- Issue #3751: str.rpartition would perform a left-partition when called with
744 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000749 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000750 was correctly parsed but parsing of subsequent arguments failed.
751
Vinay Sajip35e3b032008-09-01 14:33:59 +0000752- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000753 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
754 mechanism. In the process, fix a bug where isinstance() and issubclass(),
755 when given a tuple of classes as second argument, were looking up
756 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
757 type object.

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

898Core and Builtins
899-----------------
900
Guido van Rossumf8402962008-08-20 15:01:50 +0000901- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
902 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
903 extensions do not automatically benefit from the class attribute
904 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
905 to their tp_flags field if they care. This is a backwards
906 compatibility feature; in 3.0, all types will use the cache by
907 default.
908
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000909- Keyword arguments can now follow starred arguments. (``f(a, *args,
910 keyword=23)`` is now valid syntax.)
911
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000912- ctypes function pointers that are COM methods have a boolean True
913 value again.
914
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000915- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
916 by denying s# to parse objects that have a releasebuffer procedure,
917 and introducing s*.
918
Georg Brandl1e13ea92008-08-11 09:07:59 +0000919- Issue #3537: Fix an assertion failure when an empty but presized dict
920 object was stored in the freelist.
921
Mark Dickinsonb6467572008-08-04 21:30:09 +0000922- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
923 ValueError consistently across platforms.
924
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000925- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
926 (64bit Unix, for example), unichr() would truncate its argument and return
927 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
928
Neal Norwitze7d8be82008-07-31 17:17:14 +0000929- Apply security patches from Apple.
930
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000931- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
932 PyErr_ExceptionMatches returns 0 when an exception occurs there.
933
Antoine Pitrou92f82162008-07-25 22:22:08 +0000934- Issue #1819: function calls with several named parameters are now on
935 average 35% faster (as measured by pybench).
936
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000937- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
938 the python debugger steps into a class statement: the free variables (local
939 variables defined in an outer scope) would be deleted from the outer scope.
940
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000941- Issue #2620: Overflow checking when allocating or reallocating memory
942 was not always being done properly in some python types and extension
943 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
944 all been updated to perform better checks and places in the code that
945 would previously leak memory on the error path when such an allocation
946 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +0000953- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
954 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
955
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000956- Issue #2234: distutils failed for some versions of the cygwin compiler. The
957 version reported by these tools does not necessarily follow the python
958 version numbering scheme, so the module is less strict when parsing it.
959
Nick Coghlanf70385a2008-08-18 12:42:46 +0000960- Issue #2235: Added Py3k warnings for types which will become unhashable
961 under the stricter __hash__ inheritance rules in 3.0. Several types
962 which did not meet the rules for hash invariants and were already
963 unhashable in 3.0 have now been explicitly flagged as unhashable in
964 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
965 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
966
Brett Cannon88f801d2008-08-18 00:46:22 +0000967- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
968 imported into the module but exposed as part of the module's API.
969
Brett Cannon7b96f072008-08-18 00:41:11 +0000970- Remove an unneeded import of abc.ABCMeta from 'inspect'.

975
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000976- Issue #3575: Incremental decoder's decode function now takes bytearray
977 by using 's*' instead of 't#'.
978
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000979- Issue #2222: Fixed reference leak when occured os.rename()

Antoine Pitroude781a42008-08-09 12:43:23 +00001036 asking for a specific length. This problem only affected files opened

1080
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001081- Issue #643841: The language reference now provides more detailed

1093-----------------
1094
Georg Brandl3e483f62008-07-16 22:57:41 +00001095- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1096 its methods now allow for items objects that can be converted to
1097 an integer using operator.index().
1098
Mark Dickinson64b7e502008-07-16 09:40:03 +00001099- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1100 produced a ValueError instead of giving the correct float.
1101
Eric Smitha5fa5a22008-07-16 00:11:49 +00001102- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1103 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1104
Mark Dickinson7103aa42008-07-15 19:08:33 +00001105- Issue #3008: the float type has a new instance method 'float.hex'
1106 and a new class method 'float.fromhex' to convert floating-point
1107 numbers to and from hexadecimal strings, respectively.
1108
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001109- Issue #2235: __hash__ is once again inherited by default. To allow
1110 collections.Hashable to remain meaningful in the presence of the
1111 default hash implementation (object.__hash__), it is now possible
1112 to explicit block inheritance of hash by setting __hash__=None at
1113 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1114 level.
1115
Nick Coghlanb028f502008-07-13 14:52:36 +00001116- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1117 the parent module cannot be found while performing an absolute import.
1118 This means that an incorrectly defined __package__ attribute will
1119 now only prevent relative imports in that module rather than causing
1120 all imports from that module to fail.
1121
Nick Coghlan14ff9942008-07-08 14:21:42 +00001122- Issue #2517: Allow unicode messages in Exceptions again by correctly

1132 another thread's dictionary.
1133
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001134- Issue #3004: Minor change to slice.indices(): the start and stop
1135 arguments are now treated identically, making the behaviour easier
1136 to describe and understand. For example, slice(None, -10,
1137 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1138 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1139 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00001141- Issue #3219: Calling a function with repeated keyword arguments,
1142 f(a=2, a=23), would not cause a syntax error. This was a regression
1143 from 2.4 caused by the switch to the new compiler.

1182 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001183 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001184 content-length. The problem had been corrected in the 2.4 branch, but never

1590
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001591- On MacOS X it is now possible to install the framework in 64-bit
1592 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001593 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001594
1595 This is controlled by the configure argument ``--with-universal-archs``:
1596
1597 - ``--with-universal-archs=all``: install 4-way universal
1598
1599 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1600
1601 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1602
1603 This option should be used in combination with ``--enable-universalsdk=``.
1604
1605 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 +00001655- Issue #1631171: Re-implement the 'warnings' module in C (the
1656 original Python code has been kept as backup). This will allow for
1657 using the 'warning's machinery in such places as the parser where
1658 use of pure Python code is not possible. Both the ``showarning()``
1659 and ``formatwarning()`` gain an optional 'line' argument which is
1660 not called by default for backwards-compatibility reasons. Setting
1661 ``warnings.showwarning()`` to an implementation that lacks support
1662 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001687- The getpass module has been improved on Unix. It now uses /dev/tty
1688 by default and uses stderr instead of stdout. A GetPassWarning is
1689 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001704- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001705 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001725- Issue #2550: The approach used by client/server code for obtaining
1726 ports to listen on in network-oriented tests has been refined in an
1727 effort to facilitate running multiple instances of the entire
1728 regression test suite in parallel without issue.
1729 test_support.bind_port() has been fixed such that it will always
1730 return a unique port -- which wasn't always the case with the
1731 previous implementation, especially if socket options had been set
1732 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1733 new implementation of bind_port() will actually raise an exception
1734 if it is passed an AF_INET/SOCK_STREAM socket with either the
1735 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1736 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1737 the socket it's been passed. This currently only applies to
1738 Windows. This option prevents any other sockets from binding to the
1739 host/port we've bound to, thus removing the possibility of the
1740 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1741 when a second SOCK_STREAM socket binds and accepts to a host/port
1742 that's already been bound by another socket. The optional preferred
1743 port parameter to bind_port() has been removed. Under no
1744 circumstances should tests be hard coding ports!
1745
1746 test_support.find_unused_port() has also been introduced, which will
1747 pass a temporary socket object to bind_port() in order to obtain an
1748 unused port. The temporary socket object is then closed and
1749 deleted, and the port is returned. This method should only be used
1750 for obtaining an unused port in order to pass to an external program
1751 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1752 a parameter to a server-oriented class that doesn't give you direct
1753 access to the underlying socket used.
1754
1755 Finally, test_support.HOST has been introduced, which should be used
1756 for the host argument of any relevant socket calls (i.e. bind and
1757 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001758
1759 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001760 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001761 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1762 test_asynchat and test_socket_ssl.
1763
Georg Brandl3ee81df2008-05-17 18:14:43 +00001764 It is now possible for multiple instances of the regression test
1765 suite to run in parallel without issue.

2032-----------------
2033
Fred Drakea8ee94b2008-03-01 02:45:07 +00002034- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002035 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002040
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002041- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002042 issue 215555 for a discussion.
2043
Eric Smitha73fbe72008-02-23 03:09:44 +00002044- Added the future_builtins module, which contains hex() and oct().
2045 These are the PEP 3127 version of these functions, designed to be
2046 compatible with the hex() and oct() builtins from Python 3.0. They
2047 differ slightly in their output formats from the existing, unchanged
2048 Python 2.6 builtins. The expected usage of the future_builtins
2049 module is:
2050 from future_builtins import hex, oct
2051
Eric Smith7ef40bf2008-02-20 23:34:22 +00002052- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2053 exponents for exponents with absolute value < 100. Follows C99
2054 standard. This is a change on Windows, which would use 3 digits.
2055 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2056 so that any alterations it does to the resulting string will be
2057 available in stringlib/formatter.h (for float.__format__).
2058
Eric Smith5a3c1352008-02-19 13:21:56 +00002059- Implemented PEP 3101, Advanced String Formatting. This adds a new
2060 builtin format(); a format() method for str and unicode; a
2061 __format__() method to object, str, unicode, int, long, float, and
2062 datetime; the class string.Formatter; and the C API
2063 PyObject_Format().
2064
Georg Brandl3ee81df2008-05-17 18:14:43 +00002065- Fixed several potential crashes, all caused by specially crafted
2066 __del__ methods exploiting objects in temporarily inconsistent
2067 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002068
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002069- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002070 prevent a possible crash: an Abstract Base Class would try to access
2071 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002072
Georg Brandl3ee81df2008-05-17 18:14:43 +00002073- Fixed repr() and str() of complex numbers with infinity or nan as
2074 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002075
Georg Brandl3ee81df2008-05-17 18:14:43 +00002076- Clear all free lists during a gc.collect() of the highest generation
2077 in order to allow pymalloc to free more arenas. Python may give back
2078 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002079
Georg Brandl3ee81df2008-05-17 18:14:43 +00002080- Issue #2045: Fix an infinite recursion triggered when printing a
2081 subclass of collections.defaultdict, if its default_factory is set
2082 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002083
Christian Heimesf75dbef2008-02-08 00:11:31 +00002084- Fixed a minor memory leak in dictobject.c. The content of the free
2085 list was not freed on interpreter shutdown.
2086
Georg Brandl3ee81df2008-05-17 18:14:43 +00002087- Limit free list of method and builtin function objects to 256
2088 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002089
Georg Brandl3ee81df2008-05-17 18:14:43 +00002090- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2091 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002092 to compact the internal free lists of pre-allocted ints and floats.
2093
Georg Brandl3ee81df2008-05-17 18:14:43 +00002094- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2095 calls. Python expected the return type int but the fork familie
2096 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002097
Georg Brandl3ee81df2008-05-17 18:14:43 +00002098- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2099 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002100
Georg Brandl3ee81df2008-05-17 18:14:43 +00002101- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2102 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002103
Georg Brandl3ee81df2008-05-17 18:14:43 +00002104- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00002107- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2108 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002109
Georg Brandl3ee81df2008-05-17 18:14:43 +00002110- Patch #1473257: generator objects gain a gi_code attribute. This is
2111 the same object as the func_code attribute of the function that
2112 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002113
Georg Brandl3ee81df2008-05-17 18:14:43 +00002114- Issue #1920: "while 0" statements were completely removed by the
2115 compiler, even in the presence of an "else" clause, which is
2116 supposed to be run when the condition is false. Now the compiler
2117 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002118
Guido van Rossumeead05f2008-01-24 18:21:02 +00002119- A few crashers fixed: weakref_in_del.py (issue #1377858);
2120 loosing_dict_ref.py (issue #1303614, test67.py);
2121 borrowed_ref_[34].py (not in tracker).
2122
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002123- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002124 suppressed while an extension is loaded by calling SetErrorMode in
2125 dynload_win.c. The error is still reported properly.
2126
Georg Brandl3ee81df2008-05-17 18:14:43 +00002127- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002128 several extension methods and modules do not work without unicode
2129 support.
2130
Georg Brandl26543b12008-01-21 18:36:51 +00002131- Issue #1882: when compiling code from a string, encoding cookies in the
2132 second line of code were not always recognized correctly.
2133
Georg Brandl14404b62008-01-19 19:27:05 +00002134- Issue #1679: "0x" was taken as a valid integer literal.
2135
Georg Brandl6caad7d2008-01-26 14:19:22 +00002136- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002137 added.
2138
Christian Heimesc94e2b52008-01-14 04:13:37 +00002139- sys.float_info / PyFloat_GetInfo: The floating point information
2140 object was converted from a dict to a specialized structseq object.
2141
Georg Brandl3ee81df2008-05-17 18:14:43 +00002142- Patch #1816: Added sys.flags structseq. It exposes the status of
2143 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002144
Georg Brandl3ee81df2008-05-17 18:14:43 +00002145- Objects/structseq.c: Implemented new structseq representation. The
2146 patch makes structseqs (e.g. the return value of os.stat) more
2147 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002148
Georg Brandl3ee81df2008-05-17 18:14:43 +00002149- Patch #1700288: added a type attribute cache that caches method
2150 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002151
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002152- Bug #1776: __import__() no longer accepts filenames on any platform.
2153 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002154

2158 envvar and sys.dont_write_bytecode attribute. All these can be set
2159 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002160
Georg Brandl3ee81df2008-05-17 18:14:43 +00002161- Improve some exception messages when Windows fails to load an
2162 extension module. Now we get for example '%1 is not a valid Win32
2163 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002164

Christian Heimes0a8143f2007-12-18 23:22:54 +00002170- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002171 and INF. float("nan"), float("inf") and float("-inf") now work on
2172 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002173
Georg Brandl3ee81df2008-05-17 18:14:43 +00002174- Compiler now generates simpler and faster code for dictionary
2175 literals. The oparg for BUILD_MAP now indicates an estimated
2176 dictionary size. There is a new opcode, STORE_MAP, for adding
2177 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002206- Patch #1739468: Directories and zipfiles containing a __main__.py
2207 file can now be directly executed by passing their name to the
2208 interpreter. The directory/zipfile is automatically inserted as the
2209 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002210
Georg Brandl3ee81df2008-05-17 18:14:43 +00002211- Issue #1265: Fix a problem with sys.settrace, if the tracing
2212 function uses a generator expression when at the same time the
2213 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002214
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002215- sets and frozensets now have an isdisjoint() method.
2216

2218
Neal Norwitz44f326e2007-10-05 05:29:17 +00002219- Fix warnings found by the new version of the Coverity checker.
2220
Georg Brandl3ee81df2008-05-17 18:14:43 +00002221- The enumerate() builtin function is no longer bounded to sequences
2222 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2223 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002224
Georg Brandl3ee81df2008-05-17 18:14:43 +00002225- Issue #1686386: Tuple's tp_repr did not take into account the
2226 possibility of having a self-referential tuple, which is possible
2227 from C code. Nor did object's tp_str consider that a type's tp_str
2228 could do something that could lead to an inifinite recursion.
2229 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2230 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002231
Georg Brandl3ee81df2008-05-17 18:14:43 +00002232- Issue #1164: It was possible to trigger deadlock when using the
2233 'print' statement to write to a file since the GIL was not released
2234 as needed. Now PyObject_Print() does the right thing along with
2235 various tp_print implementations of the built-in types and those in
2236 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002237
Georg Brandl3ee81df2008-05-17 18:14:43 +00002238- Issue #1147: Exceptions were directly allowing string exceptions in
2239 their throw() method even though string exceptions no longer
2240 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002241
Georg Brandl3ee81df2008-05-17 18:14:43 +00002242- Issue #1096: Prevent a segfault from getting the repr of a very
2243 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002244
Brett Cannon1e534b52007-09-07 04:18:30 +00002245- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002246 PyObject_Call() never calling back out to Python code to trigger
2247 recursion depth updates/checks. Required the creation of a static
2248 RuntimeError instance in case normalizing an exception put the
2249 recursion check value past its limit. Fixes crashers
2250 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002251

Neal Norwitz0ac60192007-05-27 04:08:54 +00002265- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002266 __*__ attributes. (Some already existed, e.g., __doc__ and
2267 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002268
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002269- Add -3 option to the interpreter to warn about features that are
2270 deprecated and will be changed/removed in Python 3.0.
2271
Georg Brandl2134e752007-05-21 20:34:16 +00002272- Patch #1686487: you can now pass any mapping after '**' in function
2273 calls.
2274
Collin Winter62903052007-05-18 23:11:24 +00002275- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002276 "except E as target:". This is to provide forwards compatibility
2277 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002278
Brett Cannon229cee22007-05-05 01:34:02 +00002279- Deprecate BaseException.message as per PEP 352.
2280
Georg Brandl3ee81df2008-05-17 18:14:43 +00002281- Issue #1303614: don't expose object's __dict__ when the dict is

2283
Vinay Sajip8549ce32007-05-06 17:53:37 +00002284- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002285 setting a plain string, ie don't expand to single letter identifiers.
2286
Raymond Hettinger13936692007-04-11 18:40:58 +00002287- Request #1191699: Slices can now be pickled.
2288
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002289- Request #1193128: str.translate() now allows a None argument for
2290 translations that only remove characters without re-mapping the
2291 remaining characters.
2292
Georg Brandl5cb76c12007-03-21 09:00:39 +00002293- Patch #1682205: a TypeError while unpacking an iterable is no longer
2294 masked by a generic one with the message "unpack non-sequence".
2295
Neal Norwitzaa754b72007-03-21 06:39:48 +00002296- Remove unused file Python/fmod.c.
2297
Guido van Rossum143b5642007-03-23 04:58:42 +00002298- Bug #1683368: The object.__init__() and object.__new__() methods are
2299 now stricter in rejecting excess arguments. The only time when
2300 either allows excess arguments is when it is not overridden and the
2301 other one is. For backwards compatibility, when both are
2302 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002303 warning later). Also, type.__init__() insists on the same signature
2304 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002305
Georg Brandl3ee81df2008-05-17 18:14:43 +00002306- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2307 object to complex using its __complex__() method before falling back
2308 to the __float__() method. Therefore, the functions in the cmath
2309 module now can operate on objects that define a __complex__()
2310 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002311
Georg Brandl3ee81df2008-05-17 18:14:43 +00002312- Patch #1623563: allow __class__ assignment for classes with
2313 __slots__. The old and the new class are still required to have the

Georg Brandl3ee81df2008-05-17 18:14:43 +00003384 time so that opening a database previously created with the DB_DUP
3385 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3386 opens. Specifically: dictionary assignment to a DB object will
3387 replace all values for a given key when the database allows
3388 duplicate values. DB users should use DB.put(k, v) when they want
3389 to store duplicates; not DB[k] = v.

3396 characters with ASCII value less than 32. Also, it correctly quotes
3397 dots only if they occur on a single line, as opposed to the previous
3398 behavior of quoting dots if they are the second character of any
3399 line.
