42 code objects if the original filename is obsolete (which can happen if the
43 file has been renamed, moved, or if it is accessed through different paths).
44 Patch by Ziga Seilnacht and Jean-Paul Calderone.

80
Vinay Sajip6badbe92009-01-20 22:49:13 +000081- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +000082 method on file objects with closefd=False. The file descriptor is still
83 kept open but the file object behaves like a closed file. The ``FileIO``

85
Georg Brandlfa71a902008-12-05 09:08:28 +000086- Issue #3689: The list reversed iterator now supports __length_hint__

97 output compared to previous Python versions.
98
Lars Gustäbel9e2a09a2009-03-22 20:22:29 +000099- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
100 forever on incomplete input. That caused tarfile.open() to hang when used
101 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

194 do an explicit seek to the end of file (so that e.g. tell() returns the
195 file size rather than 0). This is consistent with the behaviour of the
196 traditional 2.x file object.

Amaury Forgeot d'Arc0293c802009-01-17 16:46:35 +0000198- Issue #3997: zipfiles generated with more than 65536 files could not be

229
230- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
231 302 conformant loader) will now work correctly in most cases (they
232 are still subject to the constraints that exist for all code running
233 from inside a module loaded via a PEP 302 loader and attempting to

276
Benjamin Peterson866eba92008-11-19 22:05:53 +0000277- Issue #4348: Some bytearray methods returned that didn't cause any change to
278 the bytearray, returned the same bytearray instead of a copy.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000564- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
565 PyString_FromFormat or PyErr_Format to display size_t values. The macro
566 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
567 ``printf`` function, whereas PyString_FromFormat has an independent

Antoine Pitrou0668c622008-08-26 22:42:08 +0000590 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
591 mechanism. In the process, fix a bug where isinstance() and issubclass(),

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

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000733What's New in Python 2.6 beta 3?
734================================
735
Barry Warsaw07a4a382008-08-21 01:15:08 +0000736*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000737
738Core and Builtins
739-----------------
740
Guido van Rossumf8402962008-08-20 15:01:50 +0000741- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
742 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
743 extensions do not automatically benefit from the class attribute
744 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
745 to their tp_flags field if they care. This is a backwards
746 compatibility feature; in 3.0, all types will use the cache by
747 default.
748
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000749- Keyword arguments can now follow starred arguments. (``f(a, *args,
750 keyword=23)`` is now valid syntax.)
751
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000752- ctypes function pointers that are COM methods have a boolean True
753 value again.
754
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000755- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
756 by denying s# to parse objects that have a releasebuffer procedure,
757 and introducing s*.
758
Georg Brandl1e13ea92008-08-11 09:07:59 +0000759- Issue #3537: Fix an assertion failure when an empty but presized dict
760 object was stored in the freelist.
761
Mark Dickinsonb6467572008-08-04 21:30:09 +0000762- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
763 ValueError consistently across platforms.
764
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000765- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
766 (64bit Unix, for example), unichr() would truncate its argument and return
767 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
768
Neal Norwitze7d8be82008-07-31 17:17:14 +0000769- Apply security patches from Apple.
770
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000771- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
772 PyErr_ExceptionMatches returns 0 when an exception occurs there.
773
Antoine Pitrou92f82162008-07-25 22:22:08 +0000774- Issue #1819: function calls with several named parameters are now on
775 average 35% faster (as measured by pybench).
776
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000777- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
778 the python debugger steps into a class statement: the free variables (local
779 variables defined in an outer scope) would be deleted from the outer scope.
780
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000781- Issue #2620: Overflow checking when allocating or reallocating memory
782 was not always being done properly in some python types and extension
783 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
784 all been updated to perform better checks and places in the code that
785 would previously leak memory on the error path when such an allocation
786 failed have been fixed.
787
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000788Library

795
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000796- Issue #2234: distutils failed for some versions of the cygwin compiler. The
797 version reported by these tools does not necessarily follow the python
798 version numbering scheme, so the module is less strict when parsing it.
799
Nick Coghlanf70385a2008-08-18 12:42:46 +0000800- Issue #2235: Added Py3k warnings for types which will become unhashable
801 under the stricter __hash__ inheritance rules in 3.0. Several types
802 which did not meet the rules for hash invariants and were already
803 unhashable in 3.0 have now been explicitly flagged as unhashable in
804 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
805 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
806
Brett Cannon88f801d2008-08-18 00:46:22 +0000807- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

815
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000816- Issue #3575: Incremental decoder's decode function now takes bytearray
817 by using 's*' instead of 't#'.
818
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000819- Issue #2222: Fixed reference leak when occured os.rename()
820 fails unicode conversion on 2nd parameter. (windows only)
821
Facundo Batista94f243a2008-08-17 03:38:39 +0000822- Issue 2464. urllib2 now supports a malformation in the URL received
823 in a redirect.
824

Brett Cannonabe423e2008-08-16 21:47:07 +0000827
Facundo Batistaeb90b782008-08-16 14:44:07 +0000828- Issue #2776: fixed small issue when handling an URL with double slash
829 after a 302 response in the case of not going through a proxy.
830
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000831- Issue #2676: in the email package, content-type parsing was hanging on
832 pathological input because of quadratic or exponential behaviour of a
833 regular expression.
834
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000835- Issue #3476: binary buffered reading through the new "io" library is now
836 thread-safe.
837
Brett Cannonbf3157b2008-08-14 05:00:03 +0000838- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
839 since mimetools itself is deprecated. Because modules are cached, all
840 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
841
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000842- Issue #3134: shutil referenced undefined WindowsError symbol.
843
Robert Schuppenies14646332008-08-10 11:01:53 +0000844- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
845 menu entries were not deleted.
846
Brett Cannon83e81842008-08-09 23:30:55 +0000847- Copied the implementation of reduce() to _functools.reduce() to have a
848 version that did not raise a DeprecationWarning under -3.
849
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000850- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
851 a MemoryError rather than silently stop the iteration.
852
Guido van Rossum59ce9012008-08-09 14:55:34 +0000853- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
854 to _sre.compile() will now be rejected. This should not affect anybody
855 since the re.compile() function never generates invalid re-bytecode.
856
Skip Montanaroa032bf42008-08-08 22:52:51 +0000857- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
858 upon first access it can be automatically initialized from the csv file if
859 it wasn't initialized during instantiation.
860
Brett Cannon3aa2a492008-08-06 22:28:09 +0000861- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as

903 file name rather than a ZipInfo instance, so files are extracted with
904 mode 0600 rather than 000 under Unix.
905
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000906- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
907 argument in python 2.5, this broke code that subclassed Popen to include its

940 produced a ValueError instead of giving the correct float.
941
Eric Smitha5fa5a22008-07-16 00:11:49 +0000942- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
943 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
944
Mark Dickinson7103aa42008-07-15 19:08:33 +0000945- Issue #3008: the float type has a new instance method 'float.hex'
946 and a new class method 'float.fromhex' to convert floating-point
947 numbers to and from hexadecimal strings, respectively.
948
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000949- Issue #2235: __hash__ is once again inherited by default. To allow
950 collections.Hashable to remain meaningful in the presence of the
951 default hash implementation (object.__hash__), it is now possible
952 to explicit block inheritance of hash by setting __hash__=None at
953 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
954 level.
955
Nick Coghlanb028f502008-07-13 14:52:36 +0000956- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
957 the parent module cannot be found while performing an absolute import.
958 This means that an incorrectly defined __package__ attribute will
959 now only prevent relative imports in that module rather than causing
960 all imports from that module to fail.
961
Nick Coghlan14ff9942008-07-08 14:21:42 +0000962- Issue #2517: Allow unicode messages in Exceptions again by correctly

972 another thread's dictionary.
973
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000974- Issue #3004: Minor change to slice.indices(): the start and stop
975 arguments are now treated identically, making the behaviour easier
976 to describe and understand. For example, slice(None, -10,
977 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
978 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
979 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +0000981- Issue #3219: Calling a function with repeated keyword arguments,
982 f(a=2, a=23), would not cause a syntax error. This was a regression
983 from 2.4 caused by the switch to the new compiler.

1022 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001023 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001024 content-length. The problem had been corrected in the 2.4 branch, but never

1498 use of pure Python code is not possible. Both the ``showarning()``
1499 and ``formatwarning()`` gain an optional 'line' argument which is
1500 not called by default for backwards-compatibility reasons. Setting
1501 ``warnings.showwarning()`` to an implementation that lacks support
1502 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001565- Issue #2550: The approach used by client/server code for obtaining
1566 ports to listen on in network-oriented tests has been refined in an
1567 effort to facilitate running multiple instances of the entire
1568 regression test suite in parallel without issue.
1569 test_support.bind_port() has been fixed such that it will always
1570 return a unique port -- which wasn't always the case with the
1571 previous implementation, especially if socket options had been set
1572 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1573 new implementation of bind_port() will actually raise an exception
1574 if it is passed an AF_INET/SOCK_STREAM socket with either the
1575 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1576 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1577 the socket it's been passed. This currently only applies to
1578 Windows. This option prevents any other sockets from binding to the
1579 host/port we've bound to, thus removing the possibility of the
1580 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1581 when a second SOCK_STREAM socket binds and accepts to a host/port
1582 that's already been bound by another socket. The optional preferred
1583 port parameter to bind_port() has been removed. Under no
1584 circumstances should tests be hard coding ports!
1585
1586 test_support.find_unused_port() has also been introduced, which will
1587 pass a temporary socket object to bind_port() in order to obtain an
1588 unused port. The temporary socket object is then closed and
1589 deleted, and the port is returned. This method should only be used
1590 for obtaining an unused port in order to pass to an external program
1591 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1592 a parameter to a server-oriented class that doesn't give you direct
1593 access to the underlying socket used.
1594
1595 Finally, test_support.HOST has been introduced, which should be used
1596 for the host argument of any relevant socket calls (i.e. bind and
1597 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001598
1599 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001600 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001601 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1602 test_asynchat and test_socket_ssl.
1603
Georg Brandl3ee81df2008-05-17 18:14:43 +00001604 It is now possible for multiple instances of the regression test
1605 suite to run in parallel without issue.

1873
Fred Drakea8ee94b2008-03-01 02:45:07 +00001874- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001875 644. The mode is now inherited from the py file.

1878
1879- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001880
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001881- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001882 issue 215555 for a discussion.
1883
Eric Smitha73fbe72008-02-23 03:09:44 +00001884- Added the future_builtins module, which contains hex() and oct().
1885 These are the PEP 3127 version of these functions, designed to be
1886 compatible with the hex() and oct() builtins from Python 3.0. They
1887 differ slightly in their output formats from the existing, unchanged
1888 Python 2.6 builtins. The expected usage of the future_builtins
1889 module is:
1890 from future_builtins import hex, oct
1891
Eric Smith7ef40bf2008-02-20 23:34:22 +00001892- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1893 exponents for exponents with absolute value < 100. Follows C99
1894 standard. This is a change on Windows, which would use 3 digits.
1895 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1896 so that any alterations it does to the resulting string will be
1897 available in stringlib/formatter.h (for float.__format__).
1898
Eric Smith5a3c1352008-02-19 13:21:56 +00001899- Implemented PEP 3101, Advanced String Formatting. This adds a new
1900 builtin format(); a format() method for str and unicode; a
1901 __format__() method to object, str, unicode, int, long, float, and
1902 datetime; the class string.Formatter; and the C API
1903 PyObject_Format().
1904
Georg Brandl3ee81df2008-05-17 18:14:43 +00001905- Fixed several potential crashes, all caused by specially crafted
1906 __del__ methods exploiting objects in temporarily inconsistent
1907 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001908
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001909- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001910 prevent a possible crash: an Abstract Base Class would try to access
1911 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001912
Georg Brandl3ee81df2008-05-17 18:14:43 +00001913- Fixed repr() and str() of complex numbers with infinity or nan as
1914 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001915
Georg Brandl3ee81df2008-05-17 18:14:43 +00001916- Clear all free lists during a gc.collect() of the highest generation
1917 in order to allow pymalloc to free more arenas. Python may give back
1918 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001919
Georg Brandl3ee81df2008-05-17 18:14:43 +00001920- Issue #2045: Fix an infinite recursion triggered when printing a
1921 subclass of collections.defaultdict, if its default_factory is set
1922 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001923
Christian Heimesf75dbef2008-02-08 00:11:31 +00001924- Fixed a minor memory leak in dictobject.c. The content of the free
1925 list was not freed on interpreter shutdown.
1926
Georg Brandl3ee81df2008-05-17 18:14:43 +00001927- Limit free list of method and builtin function objects to 256
1928 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001929
Georg Brandl3ee81df2008-05-17 18:14:43 +00001930- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1931 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001932 to compact the internal free lists of pre-allocted ints and floats.
1933
Georg Brandl3ee81df2008-05-17 18:14:43 +00001934- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1935 calls. Python expected the return type int but the fork familie
1936 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001937
Georg Brandl3ee81df2008-05-17 18:14:43 +00001938- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1939 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001940
Georg Brandl3ee81df2008-05-17 18:14:43 +00001941- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1942 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001947- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1948 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001949
Georg Brandl3ee81df2008-05-17 18:14:43 +00001950- Patch #1473257: generator objects gain a gi_code attribute. This is
1951 the same object as the func_code attribute of the function that
1952 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001953
Georg Brandl3ee81df2008-05-17 18:14:43 +00001954- Issue #1920: "while 0" statements were completely removed by the
1955 compiler, even in the presence of an "else" clause, which is
1956 supposed to be run when the condition is false. Now the compiler
1957 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001958
Guido van Rossumeead05f2008-01-24 18:21:02 +00001959- A few crashers fixed: weakref_in_del.py (issue #1377858);
1960 loosing_dict_ref.py (issue #1303614, test67.py);
1961 borrowed_ref_[34].py (not in tracker).
1962
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001963- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001964 suppressed while an extension is loaded by calling SetErrorMode in
1965 dynload_win.c. The error is still reported properly.
1966
Georg Brandl3ee81df2008-05-17 18:14:43 +00001967- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001968 several extension methods and modules do not work without unicode
1969 support.
1970
Georg Brandl26543b12008-01-21 18:36:51 +00001971- Issue #1882: when compiling code from a string, encoding cookies in the
1972 second line of code were not always recognized correctly.
1973
Georg Brandl14404b62008-01-19 19:27:05 +00001974- Issue #1679: "0x" was taken as a valid integer literal.
1975
Georg Brandl6caad7d2008-01-26 14:19:22 +00001976- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001977 added.
1978
Christian Heimesc94e2b52008-01-14 04:13:37 +00001979- sys.float_info / PyFloat_GetInfo: The floating point information
1980 object was converted from a dict to a specialized structseq object.
1981
Georg Brandl3ee81df2008-05-17 18:14:43 +00001982- Patch #1816: Added sys.flags structseq. It exposes the status of
1983 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001984
Georg Brandl3ee81df2008-05-17 18:14:43 +00001985- Objects/structseq.c: Implemented new structseq representation. The
1986 patch makes structseqs (e.g. the return value of os.stat) more
1987 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001988
Georg Brandl3ee81df2008-05-17 18:14:43 +00001989- Patch #1700288: added a type attribute cache that caches method
1990 accesses, resulting in speedups in heavily object-oriented code.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002001- Improve some exception messages when Windows fails to load an
2002 extension module. Now we get for example '%1 is not a valid Win32
2003 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002014- Compiler now generates simpler and faster code for dictionary
2015 literals. The oparg for BUILD_MAP now indicates an estimated
2016 dictionary size. There is a new opcode, STORE_MAP, for adding
2017 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002046- Patch #1739468: Directories and zipfiles containing a __main__.py
2047 file can now be directly executed by passing their name to the
2048 interpreter. The directory/zipfile is automatically inserted as the
2049 first entry in sys.path.

2060
Georg Brandl3ee81df2008-05-17 18:14:43 +00002061- The enumerate() builtin function is no longer bounded to sequences
2062 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2063 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002064
Georg Brandl3ee81df2008-05-17 18:14:43 +00002065- Issue #1686386: Tuple's tp_repr did not take into account the
2066 possibility of having a self-referential tuple, which is possible
2067 from C code. Nor did object's tp_str consider that a type's tp_str
2068 could do something that could lead to an inifinite recursion.
2069 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2070 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002071
Georg Brandl3ee81df2008-05-17 18:14:43 +00002072- Issue #1164: It was possible to trigger deadlock when using the
2073 'print' statement to write to a file since the GIL was not released
2074 as needed. Now PyObject_Print() does the right thing along with
2075 various tp_print implementations of the built-in types and those in
2076 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00002085- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002086 PyObject_Call() never calling back out to Python code to trigger
2087 recursion depth updates/checks. Required the creation of a static
2088 RuntimeError instance in case normalizing an exception put the
2089 recursion check value past its limit. Fixes crashers
2090 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002105- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002106 __*__ attributes. (Some already existed, e.g., __doc__ and
2107 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002108
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002109- Add -3 option to the interpreter to warn about features that are

2113 calls.
2114
Collin Winter62903052007-05-18 23:11:24 +00002115- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002116 "except E as target:". This is to provide forwards compatibility
2117 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002118
Brett Cannon229cee22007-05-05 01:34:02 +00002119- Deprecate BaseException.message as per PEP 352.

2123
Vinay Sajip8549ce32007-05-06 17:53:37 +00002124- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002125 setting a plain string, ie don't expand to single letter identifiers.
2126
Raymond Hettinger13936692007-04-11 18:40:58 +00002127- Request #1191699: Slices can now be pickled.
2128
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002129- Request #1193128: str.translate() now allows a None argument for

2131 remaining characters.
2132
Georg Brandl5cb76c12007-03-21 09:00:39 +00002133- Patch #1682205: a TypeError while unpacking an iterable is no longer

2137
Guido van Rossum143b5642007-03-23 04:58:42 +00002138- Bug #1683368: The object.__init__() and object.__new__() methods are
2139 now stricter in rejecting excess arguments. The only time when
2140 either allows excess arguments is when it is not overridden and the
2141 other one is. For backwards compatibility, when both are
2142 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002143 warning later). Also, type.__init__() insists on the same signature
2144 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002145
Georg Brandl3ee81df2008-05-17 18:14:43 +00002146- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2147 object to complex using its __complex__() method before falling back
2148 to the __float__() method. Therefore, the functions in the cmath
2149 module now can operate on objects that define a __complex__()
2150 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002151
Georg Brandl3ee81df2008-05-17 18:14:43 +00002152- Patch #1623563: allow __class__ assignment for classes with
2153 __slots__. The old and the new class are still required to have the
2154 same slot names.

2161 its type.

2167
Georg Brandl7b9c5552007-03-12 14:30:05 +00002168- Bug #1678647: write a newline after printing an exception in any
2169 case, even when converting the value to a string failed.
2170
Georg Brandl871f1bc2007-03-12 13:17:36 +00002171- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002172 its argument, if it exists. If not, it will work like before. This
2173 allows customizing the output of dir() in the presence of a
2174 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002175
Collin Winter276887b2007-03-12 16:11:39 +00002176- Patch #922167: Python no longer segfaults when faced with infinitely
2177 self-recursive reload() calls (as reported by bug #742342).
2178
Georg Brandl3ee81df2008-05-17 18:14:43 +00002179- Patch #1675981: remove unreachable code from ``type.__new__()``

2183 parthensized forms. This means complex(repr(x)) now works instead of
2184 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002185
Georg Brandlaa2321b2007-03-07 00:40:28 +00002186- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002187 makes the filenames the warning module prints much more sensible
2188 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002189

Georg Brandl0fca97a2007-03-05 22:28:08 +00002201- Patch #1674228: when assigning a slice (old-style), check for the
2202 sq_ass_slice instead of the sq_slice slot.
2203
Georg Brandl3ee81df2008-05-17 18:14:43 +00002204- When printing an unraisable error, don't print exceptions. before
2205 the name. This duplicates the behavior whening normally printing
2206 exceptions.

2772
Georg Brandl92a6bae2007-03-13 17:43:32 +00002773- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002774 are set for invalid interpolation sequences that would lead to
2775 errors on reading back those values.

2831 TestCase and TestSuite subclasses (not instances) are no longer
2832 accepted in TestSuite.addTest(). This should cause no
2833 incompatibility since it never made sense with ordinary subclasses
2834 -- the failure just occurred later, with a more cumbersome
2835 exception.

3119 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003120
Georg Brandl3ee81df2008-05-17 18:14:43 +00003121- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003122 that the SMTP.starttls() caller no longer needs to call ehlo()
3123 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124 does not claim to support starttls. Adds the
3125 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3206 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3207 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00003209

Georg Brandl3ee81df2008-05-17 18:14:43 +00003224 time so that opening a database previously created with the DB_DUP
3225 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3226 opens. Specifically: dictionary assignment to a DB object will
3227 replace all values for a given key when the database allows
3228 duplicate values. DB users should use DB.put(k, v) when they want

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00003508- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00003509 periodic threadstate and signal checking in tight loops. By
3510 default, this option is turned-off. It should only be enabled in
3511 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00003512

3563
Georg Brandl3ee81df2008-05-17 18:14:43 +00003564- Unified naming convention for free lists and their limits. All free
3565 lists in Object/ are named ``free_list``, the counter ``numfree``
3566 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3567 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003568
Georg Brandl3ee81df2008-05-17 18:14:43 +00003569- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3570 to ``PyTuple_SetItem``, it can be used to populate a brand new
3571 frozenset; but it does not steal a reference to the added item.

3583
Georg Brandl3ee81df2008-05-17 18:14:43 +00003584- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3585 of w# format code incorrectly truncated the length to an int, even
3586 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3587 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003588

3609
3610- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3611 outside of pystate.c and should not be necessary.
3612
Georg Brandl3ee81df2008-05-17 18:14:43 +00003613- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3614 absolute imports. In earlier versions they might have used relative
3615 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003616
Georg Brandl3ee81df2008-05-17 18:14:43 +00003617- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3618 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003619
Georg Brandl3ee81df2008-05-17 18:14:43 +00003620- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003645- Removed the macfs module. It had been deprecated since Python 2.5.
3646 This lead to the deprecation of macostools.touched() as it relied
3647 solely on macfs and was a no-op under OS X.
