Mark Dickinson80068da2010-06-05 11:59:41 +000015- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsonb671c292010-06-05 12:15:35 +000016 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
17 arises from the "Overriding __eq__ blocks inheritance ..." warning
18 when turned into an exception: in this case the exception simply
19 gets ignored.

Mark Dickinsone02c9d22010-05-07 13:23:18 +000033- Issue #1533: fix inconsistency in range function argument
34 processing: any non-float non-integer argument is now converted to

36 small arguments were treated this way; larger arguments (those whose
37 __int__ was outside the range of a C long) would produce a TypeError.

62- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
63 embedders of the interpreter to set sys.argv without also modifying
64 sys.path. This helps fix `CVE-2008-5983
65 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

1301 do an explicit seek to the end of file (so that e.g. tell() returns the

1336
1337- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1338 302 conformant loader) will now work correctly in most cases (they
1339 are still subject to the constraints that exist for all code running
1340 from inside a module loaded via a PEP 302 loader and attempting to

1499What's New in Python 2.6.1
1500==========================
1501
1502*Release date: 04-Dec-2008*
1503
1504Core and Builtins
1505-----------------
1506
1507- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1508 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1509 instead of throwing a MemoryError.
1510
1511- Issue #4367: Python would segfault during compiling when the unicodedata
1512 module couldn't be imported and \N escapes were present.
1513
1514- Issue #4348: Some bytearray methods returned that didn't cause any change to
1515 the bytearray, returned the same bytearray instead of a copy.
1516
1517- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1518
1519- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1520
1521- Issue #4048: The parser module now correctly validates relative imports.
1522
1523- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1524 exec statement.
1525
1526- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1527 method does not return iterators for the 4th and 5th items.
1528
1529- Issue #4209: Enabling unicode_literals and the print_function in the same
1530 __future__ import didn't work.
1531
1532- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1533 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1534 really executed because I cannot move to such directory on win2k)
1535
1536- Issue #4069: When set.remove(element) is used with a set element, the element
1537 is temporarily replaced with an equivalent frozenset. But the eventual
1538 KeyError would always report the empty frozenset([]) as the missing key. Now
1539 it correctly refers to the initial element.
1540
1541- Fixed C99 style comments in several files. Python is now C89 compatible
1542 again.

1690
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001691- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1692 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1693 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1694 ``printf`` function, whereas PyString_FromFormat has an independent
1695 implementation and uses "%zd" on all platforms for size_t values.
1696 This makes a difference on win64, where ``printf`` needs "%Id" to display
1697 64bit values.

1703 object; previously an int would be returned for small values. the __long__
1704 method is allowed to return either an int or a long, but the behaviour of
1705 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001707- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001713 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001714 was correctly parsed but parsing of subsequent arguments failed.
1715
Vinay Sajip35e3b032008-09-01 14:33:59 +00001716- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001717 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1718 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1719 when given a tuple of classes as second argument, were looking up
1720 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1721 type object.
1722
Neal Norwitz18aa3882008-08-24 05:04:52 +00001723- Fix crashes on memory allocation failure found with failmalloc.

1863-----------------
1864
Guido van Rossumf8402962008-08-20 15:01:50 +00001865- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1866 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1867 extensions do not automatically benefit from the class attribute
1868 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1869 to their tp_flags field if they care. This is a backwards
1870 compatibility feature; in 3.0, all types will use the cache by
1871 default.
1872
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001873- Keyword arguments can now follow starred arguments. (``f(a, *args,

Thomas Heller0ad5ae02008-08-19 19:25:04 +00001876- ctypes function pointers that are COM methods have a boolean True
1877 value again.
1878
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001879- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1880 by denying s# to parse objects that have a releasebuffer procedure,
1881 and introducing s*.

Mark Dickinsonb6467572008-08-04 21:30:09 +00001886- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1887 ValueError consistently across platforms.
1888
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001889- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1890 (64bit Unix, for example), unichr() would truncate its argument and return
1891 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1892
Neal Norwitze7d8be82008-07-31 17:17:14 +00001893- Apply security patches from Apple.
1894
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001895- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1896 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1897
Antoine Pitrou92f82162008-07-25 22:22:08 +00001898- Issue #1819: function calls with several named parameters are now on
1899 average 35% faster (as measured by pybench).
1900
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001901- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1902 the python debugger steps into a class statement: the free variables (local
1903 variables defined in an outer scope) would be deleted from the outer scope.
1904
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001905- Issue #2620: Overflow checking when allocating or reallocating memory
1906 was not always being done properly in some python types and extension
1907 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1908 all been updated to perform better checks and places in the code that
1909 would previously leak memory on the error path when such an allocation
1910 failed have been fixed.

1919
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001920- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1921 version reported by these tools does not necessarily follow the python
1922 version numbering scheme, so the module is less strict when parsing it.
1923
Nick Coghlanf70385a2008-08-18 12:42:46 +00001924- Issue #2235: Added Py3k warnings for types which will become unhashable
1925 under the stricter __hash__ inheritance rules in 3.0. Several types
1926 which did not meet the rules for hash invariants and were already
1927 unhashable in 3.0 have now been explicitly flagged as unhashable in
1928 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1929 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1930
Brett Cannon88f801d2008-08-18 00:46:22 +00001931- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00001962- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1963 since mimetools itself is deprecated. Because modules are cached, all
1964 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1965
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001966- Issue #3134: shutil referenced undefined WindowsError symbol.

1976
Guido van Rossum59ce9012008-08-09 14:55:34 +00001977- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1978 to _sre.compile() will now be rejected. This should not affect anybody
1979 since the re.compile() function never generates invalid re-bytecode.
1980
Skip Montanaroa032bf42008-08-08 22:52:51 +00001981- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1982 upon first access it can be automatically initialized from the csv file if
1983 it wasn't initialized during instantiation.
1984
Brett Cannon3aa2a492008-08-06 22:28:09 +00001985- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1986 the reload() built-in has been removed.
1987
Brett Cannon7e30b672008-08-04 21:52:25 +00001988- Changed code in the following modules/packages to remove warnings raised

1997 raised an AttributeError.
1998
Benjamin Peterson01a24322008-07-28 23:35:27 +00001999- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002000 asking for a specific length. This problem only affected files opened
2001 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002002

2027 file name rather than a ZipInfo instance, so files are extracted with
2028 mode 0600 rather than 000 under Unix.
2029
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002030- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2031 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002042- Issue #2235: the C API function PyObject_HashNotImplemented and its
2043 interaction with the tp_hash slot (added in 2.6b2) are now documented
2044
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002045- Issue #643841: The language reference now provides more detailed
2046 coverage of the lookup process for special methods. The disclaimers
2047 regarding lack of coverage of new-style classes have also been
2048 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002056Core and Builtins
2057-----------------
2058
Georg Brandl3e483f62008-07-16 22:57:41 +00002059- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2060 its methods now allow for items objects that can be converted to
2061 an integer using operator.index().
2062
Mark Dickinson64b7e502008-07-16 09:40:03 +00002063- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2064 produced a ValueError instead of giving the correct float.
2065
Eric Smitha5fa5a22008-07-16 00:11:49 +00002066- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2067 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2068
Mark Dickinson7103aa42008-07-15 19:08:33 +00002069- Issue #3008: the float type has a new instance method 'float.hex'
2070 and a new class method 'float.fromhex' to convert floating-point
2071 numbers to and from hexadecimal strings, respectively.
2072
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002073- Issue #2235: __hash__ is once again inherited by default. To allow
2074 collections.Hashable to remain meaningful in the presence of the
2075 default hash implementation (object.__hash__), it is now possible
2076 to explicit block inheritance of hash by setting __hash__=None at
2077 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2078 level.
2079
Nick Coghlanb028f502008-07-13 14:52:36 +00002080- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2081 the parent module cannot be found while performing an absolute import.
2082 This means that an incorrectly defined __package__ attribute will
2083 now only prevent relative imports in that module rather than causing
2084 all imports from that module to fail.
2085
Nick Coghlan14ff9942008-07-08 14:21:42 +00002086- Issue #2517: Allow unicode messages in Exceptions again by correctly
2087 bypassing the instance dictionary when looking up __unicode__ on
2088 new-style classes.
2089
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002090- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2091 set to a custom object whose write() method happens to install
2092 another file in sys.stdout.
2093
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002094- Issue #3088: Corrected a race condition in classes derived from
2095 threading.local: the first member set by a thread could be saved in
2096 another thread's dictionary.
2097
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002098- Issue #3004: Minor change to slice.indices(): the start and stop
2099 arguments are now treated identically, making the behaviour easier
2100 to describe and understand. For example, slice(None, -10,
2101 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2102 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2103 10, -1).
2104
Georg Brandl278fc502008-07-19 12:46:12 +00002105- Issue #3219: Calling a function with repeated keyword arguments,
2106 f(a=2, a=23), would not cause a syntax error. This was a regression
2107 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002108
Georg Brandl278fc502008-07-19 12:46:12 +00002109- Issue #2862: Make int and float freelist management consistent with
2110 other freelists. Changes their CompactFreeList apis into
2111 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002112

2114-------
2115
Thomas Heller57adf222008-08-14 19:10:48 +00002116- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2117 api functions without holding the GIL, which could lead to a fatal
2118 error when they failed.
2119
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002120- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2134 a valid dlerror() message.
2135
Thomas Heller2bad6572008-07-15 17:19:50 +00002136- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2137 incomplete structure was created.
2138

2142
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002143- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002144
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002145- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2146 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002147 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002148 content-length. The problem had been corrected in the 2.4 branch, but never
2149 merged into trunk.
2150
Georg Brandle78fbcc2008-07-05 10:13:36 +00002151- Issue #2663: add filtering capability to shutil.copytree().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002557 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002558
2559 This is controlled by the configure argument ``--with-universal-archs``:
2560
2561 - ``--with-universal-archs=all``: install 4-way universal
2562
2563 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2564
2565 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2566
2567 This option should be used in combination with ``--enable-universalsdk=``.
2568
2569 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 +00002619- Issue #1631171: Re-implement the 'warnings' module in C (the
2620 original Python code has been kept as backup). This will allow for
2621 using the 'warning's machinery in such places as the parser where
2622 use of pure Python code is not possible. Both the ``showarning()``
2623 and ``formatwarning()`` gain an optional 'line' argument which is
2624 not called by default for backwards-compatibility reasons. Setting
2625 ``warnings.showwarning()`` to an implementation that lacks support
2626 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002651- The getpass module has been improved on Unix. It now uses /dev/tty
2652 by default and uses stderr instead of stdout. A GetPassWarning is
2653 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002689- Issue #2550: The approach used by client/server code for obtaining
2690 ports to listen on in network-oriented tests has been refined in an
2691 effort to facilitate running multiple instances of the entire
2692 regression test suite in parallel without issue.
2693 test_support.bind_port() has been fixed such that it will always
2694 return a unique port -- which wasn't always the case with the
2695 previous implementation, especially if socket options had been set
2696 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2697 new implementation of bind_port() will actually raise an exception
2698 if it is passed an AF_INET/SOCK_STREAM socket with either the
2699 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2700 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2701 the socket it's been passed. This currently only applies to
2702 Windows. This option prevents any other sockets from binding to the
2703 host/port we've bound to, thus removing the possibility of the
2704 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2705 when a second SOCK_STREAM socket binds and accepts to a host/port
2706 that's already been bound by another socket. The optional preferred
2707 port parameter to bind_port() has been removed. Under no
2708 circumstances should tests be hard coding ports!
2709
2710 test_support.find_unused_port() has also been introduced, which will
2711 pass a temporary socket object to bind_port() in order to obtain an
2712 unused port. The temporary socket object is then closed and
2713 deleted, and the port is returned. This method should only be used
2714 for obtaining an unused port in order to pass to an external program
2715 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2716 a parameter to a server-oriented class that doesn't give you direct
2717 access to the underlying socket used.
2718
2719 Finally, test_support.HOST has been introduced, which should be used
2720 for the host argument of any relevant socket calls (i.e. bind and
2721 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002722

2996-----------------
2997
Fred Drakea8ee94b2008-03-01 02:45:07 +00002998- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002999 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003000
Georg Brandlad61bc82008-02-23 15:11:18 +00003001- Issue #2067: file.__exit__() now calls subclasses' close() method.
3002
3003- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003004
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003005- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003006 issue 215555 for a discussion.
3007
Eric Smitha73fbe72008-02-23 03:09:44 +00003008- Added the future_builtins module, which contains hex() and oct().
3009 These are the PEP 3127 version of these functions, designed to be
3010 compatible with the hex() and oct() builtins from Python 3.0. They
3011 differ slightly in their output formats from the existing, unchanged
3012 Python 2.6 builtins. The expected usage of the future_builtins
3013 module is:
3014 from future_builtins import hex, oct
3015
Eric Smith7ef40bf2008-02-20 23:34:22 +00003016- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3017 exponents for exponents with absolute value < 100. Follows C99
3018 standard. This is a change on Windows, which would use 3 digits.
3019 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3020 so that any alterations it does to the resulting string will be
3021 available in stringlib/formatter.h (for float.__format__).
3022
Eric Smith5a3c1352008-02-19 13:21:56 +00003023- Implemented PEP 3101, Advanced String Formatting. This adds a new
3024 builtin format(); a format() method for str and unicode; a
3025 __format__() method to object, str, unicode, int, long, float, and
3026 datetime; the class string.Formatter; and the C API
3027 PyObject_Format().
3028
Georg Brandl3ee81df2008-05-17 18:14:43 +00003029- Fixed several potential crashes, all caused by specially crafted
3030 __del__ methods exploiting objects in temporarily inconsistent
3031 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003032
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003033- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003034 prevent a possible crash: an Abstract Base Class would try to access
3035 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003036
Georg Brandl3ee81df2008-05-17 18:14:43 +00003037- Fixed repr() and str() of complex numbers with infinity or nan as
3038 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003039
Georg Brandl3ee81df2008-05-17 18:14:43 +00003040- Clear all free lists during a gc.collect() of the highest generation
3041 in order to allow pymalloc to free more arenas. Python may give back
3042 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003043
Georg Brandl3ee81df2008-05-17 18:14:43 +00003044- Issue #2045: Fix an infinite recursion triggered when printing a
3045 subclass of collections.defaultdict, if its default_factory is set
3046 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003047
Christian Heimesf75dbef2008-02-08 00:11:31 +00003048- Fixed a minor memory leak in dictobject.c. The content of the free
3049 list was not freed on interpreter shutdown.
3050
Georg Brandl5a7eca12010-03-21 19:29:04 +00003051- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003052 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003053
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3055 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003056 to compact the internal free lists of pre-allocted ints and floats.
3057
Georg Brandl3ee81df2008-05-17 18:14:43 +00003058- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3059 calls. Python expected the return type int but the fork familie
3060 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003061
Georg Brandl3ee81df2008-05-17 18:14:43 +00003062- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3063 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003064
Georg Brandl3ee81df2008-05-17 18:14:43 +00003065- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3066 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003067
Georg Brandl3ee81df2008-05-17 18:14:43 +00003068- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3069 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003070
Georg Brandl3ee81df2008-05-17 18:14:43 +00003071- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3072 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003073
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- Patch #1473257: generator objects gain a gi_code attribute. This is
3075 the same object as the func_code attribute of the function that
3076 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003077
Georg Brandl3ee81df2008-05-17 18:14:43 +00003078- Issue #1920: "while 0" statements were completely removed by the
3079 compiler, even in the presence of an "else" clause, which is
3080 supposed to be run when the condition is false. Now the compiler
3081 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003082
Guido van Rossumeead05f2008-01-24 18:21:02 +00003083- A few crashers fixed: weakref_in_del.py (issue #1377858);
3084 loosing_dict_ref.py (issue #1303614, test67.py);
3085 borrowed_ref_[34].py (not in tracker).
3086
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003087- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003088 suppressed while an extension is loaded by calling SetErrorMode in
3089 dynload_win.c. The error is still reported properly.
3090
Georg Brandl3ee81df2008-05-17 18:14:43 +00003091- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003092 several extension methods and modules do not work without unicode
3093 support.
3094
Georg Brandl26543b12008-01-21 18:36:51 +00003095- Issue #1882: when compiling code from a string, encoding cookies in the
3096 second line of code were not always recognized correctly.
3097
Georg Brandl14404b62008-01-19 19:27:05 +00003098- Issue #1679: "0x" was taken as a valid integer literal.
3099
Georg Brandl6caad7d2008-01-26 14:19:22 +00003100- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003101 added.
3102
Christian Heimesc94e2b52008-01-14 04:13:37 +00003103- sys.float_info / PyFloat_GetInfo: The floating point information
3104 object was converted from a dict to a specialized structseq object.
3105
Georg Brandl3ee81df2008-05-17 18:14:43 +00003106- Patch #1816: Added sys.flags structseq. It exposes the status of
3107 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003108
Georg Brandl3ee81df2008-05-17 18:14:43 +00003109- Objects/structseq.c: Implemented new structseq representation. The
3110 patch makes structseqs (e.g. the return value of os.stat) more
3111 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003112
Georg Brandl3ee81df2008-05-17 18:14:43 +00003113- Patch #1700288: added a type attribute cache that caches method
3114 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003115
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003116- Bug #1776: __import__() no longer accepts filenames on any platform.
3117 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003118
Georg Brandlaed6c662008-01-07 17:25:53 +00003119- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3120
Georg Brandl3ee81df2008-05-17 18:14:43 +00003121- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3122 envvar and sys.dont_write_bytecode attribute. All these can be set
3123 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003124
Georg Brandl3ee81df2008-05-17 18:14:43 +00003125- Improve some exception messages when Windows fails to load an
3126 extension module. Now we get for example '%1 is not a valid Win32
3127 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003128
Georg Brandl3ee81df2008-05-17 18:14:43 +00003129- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003131- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3132 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003133
Christian Heimes0a8143f2007-12-18 23:22:54 +00003134- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003135 and INF. float("nan"), float("inf") and float("-inf") now work on
3136 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003137
Georg Brandl3ee81df2008-05-17 18:14:43 +00003138- Compiler now generates simpler and faster code for dictionary
3139 literals. The oparg for BUILD_MAP now indicates an estimated
3140 dictionary size. There is a new opcode, STORE_MAP, for adding
3141 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003142
Georg Brandl3ee81df2008-05-17 18:14:43 +00003143- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003148- Issue #1538: Avoid copying string in split/rsplit if the split char
3149 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003150
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003151- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003152 SystemError.
3153
Nick Coghlanef01d822007-12-03 12:55:17 +00003154- PEP 366: Allow explicit relative imports when executing modules
3155 inside packages with the -m switch via a new module level
3156 __package__ attribute.
3157
Georg Brandl3ee81df2008-05-17 18:14:43 +00003158- Issue #1402: Fix a crash on exit, when another thread is still
3159 running, and if the deallocation of its frames somehow calls the
3160 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003161

Georg Brandl3ee81df2008-05-17 18:14:43 +00003175- Issue #1265: Fix a problem with sys.settrace, if the tracing
3176 function uses a generator expression when at the same time the
3177 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003178
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003179- sets and frozensets now have an isdisjoint() method.
3180
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003181- optimize the performance of builtin.sum().
3182
Neal Norwitz44f326e2007-10-05 05:29:17 +00003183- Fix warnings found by the new version of the Coverity checker.
3184
Georg Brandl5a7eca12010-03-21 19:29:04 +00003185- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003186 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3187 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003188
Georg Brandl3ee81df2008-05-17 18:14:43 +00003189- Issue #1686386: Tuple's tp_repr did not take into account the
3190 possibility of having a self-referential tuple, which is possible
3191 from C code. Nor did object's tp_str consider that a type's tp_str
3192 could do something that could lead to an inifinite recursion.
3193 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3194 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003195
Georg Brandl3ee81df2008-05-17 18:14:43 +00003196- Issue #1164: It was possible to trigger deadlock when using the
3197 'print' statement to write to a file since the GIL was not released
3198 as needed. Now PyObject_Print() does the right thing along with
3199 various tp_print implementations of the built-in types and those in
3200 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003201
Georg Brandl3ee81df2008-05-17 18:14:43 +00003202- Issue #1147: Exceptions were directly allowing string exceptions in
3203 their throw() method even though string exceptions no longer
3204 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003205

Brett Cannon1e534b52007-09-07 04:18:30 +00003209- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003210 PyObject_Call() never calling back out to Python code to trigger
3211 recursion depth updates/checks. Required the creation of a static
3212 RuntimeError instance in case normalizing an exception put the
3213 recursion check value past its limit. Fixes crashers
3214 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003229- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003230 __*__ attributes. (Some already existed, e.g., __doc__ and
3231 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003232
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003233- Add -3 option to the interpreter to warn about features that are

3238
Collin Winter62903052007-05-18 23:11:24 +00003239- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003240 "except E as target:". This is to provide forwards compatibility
3241 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003242
Brett Cannon229cee22007-05-05 01:34:02 +00003243- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003248- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003249 setting a plain string, ie don't expand to single letter identifiers.
3250
Raymond Hettinger13936692007-04-11 18:40:58 +00003251- Request #1191699: Slices can now be pickled.
3252
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003253- Request #1193128: str.translate() now allows a None argument for

3261
Guido van Rossum143b5642007-03-23 04:58:42 +00003262- Bug #1683368: The object.__init__() and object.__new__() methods are
3263 now stricter in rejecting excess arguments. The only time when
3264 either allows excess arguments is when it is not overridden and the
3265 other one is. For backwards compatibility, when both are
3266 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003267 warning later). Also, type.__init__() insists on the same signature
3268 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003269
Georg Brandl3ee81df2008-05-17 18:14:43 +00003270- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3271 object to complex using its __complex__() method before falling back
3272 to the __float__() method. Therefore, the functions in the cmath
3273 module now can operate on objects that define a __complex__()
3274 method.

3277 __slots__. The old and the new class are still required to have the
3278 same slot names.

3291
Georg Brandl7b9c5552007-03-12 14:30:05 +00003292- Bug #1678647: write a newline after printing an exception in any
3293 case, even when converting the value to a string failed.
3294
Georg Brandl871f1bc2007-03-12 13:17:36 +00003295- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003296 its argument, if it exists. If not, it will work like before. This
3297 allows customizing the output of dir() in the presence of a
3298 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003299
Collin Winter276887b2007-03-12 16:11:39 +00003300- Patch #922167: Python no longer segfaults when faced with infinitely
3301 self-recursive reload() calls (as reported by bug #742342).
3302

3307 parthensized forms. This means complex(repr(x)) now works instead of
3308 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003309
Georg Brandlaa2321b2007-03-07 00:40:28 +00003310- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003311 makes the filenames the warning module prints much more sensible
3312 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003313

Georg Brandl0fca97a2007-03-05 22:28:08 +00003325- Patch #1674228: when assigning a slice (old-style), check for the
3326 sq_ass_slice instead of the sq_slice slot.
3327
Georg Brandl3ee81df2008-05-17 18:14:43 +00003328- When printing an unraisable error, don't print exceptions. before
3329 the name. This duplicates the behavior whening normally printing
3330 exceptions.

3339 created a weakref on itself during a __del__ call for new-style
3340 classes (classic classes still have the bug).

3953
Georg Brandl3ee81df2008-05-17 18:14:43 +00003954- unittest now verifies more of its assumptions. In particular,

3956 accepted in TestSuite.addTest(). This should cause no
3957 incompatibility since it never made sense with ordinary subclasses
3958 -- the failure just occurred later, with a more cumbersome
3959 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004240- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4241 with RFC 3207 and forgets any knowledge obtained from the server not
4242 obtained from the TLS negotiation itself. Patch contributed by Bill
4243 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004244
Georg Brandl3ee81df2008-05-17 18:14:43 +00004245- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004246 that the SMTP.starttls() caller no longer needs to call ehlo()
4247 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004248 does not claim to support starttls. Adds the
4249 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4330 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4331 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004348 time so that opening a database previously created with the DB_DUP
4349 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4350 opens. Specifically: dictionary assignment to a DB object will
4351 replace all values for a given key when the database allows
4352 duplicate values. DB users should use DB.put(k, v) when they want
4353 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004354

4360 characters with ASCII value less than 32. Also, it correctly quotes
4361 dots only if they occur on a single line, as opposed to the previous
4362 behavior of quoting dots if they are the second character of any
4363 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004364

Georg Brandl3ee81df2008-05-17 18:14:43 +00004680- Makefile.pre.in(buildbottest): Run an optional script
4681 pybuildbot.identify to include some information about the build
4682 environment.

4686-----
4687
Georg Brandl3ee81df2008-05-17 18:14:43 +00004688- Unified naming convention for free lists and their limits. All free
4689 lists in Object/ are named ``free_list``, the counter ``numfree``
4690 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4691 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004692
Georg Brandl3ee81df2008-05-17 18:14:43 +00004693- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4694 to ``PyTuple_SetItem``, it can be used to populate a brand new
4695 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004696
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004697- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004698
Georg Brandl3ee81df2008-05-17 18:14:43 +00004699- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4700 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4701 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004702
4703- Patch #1720595: add T_BOOL to the range of structmember types.
4704
4705- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4706 ``PyFloat_GetInfo()`` to the float API.
4707
Georg Brandl3ee81df2008-05-17 18:14:43 +00004708- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4709 of w# format code incorrectly truncated the length to an int, even
4710 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4711 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004712
Georg Brandl3ee81df2008-05-17 18:14:43 +00004713- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4714 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004715
Georg Brandl3ee81df2008-05-17 18:14:43 +00004716- PEP 3123: Provide forward compatibility with Python 3.0, while
4717 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4718 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004719
Georg Brandl3ee81df2008-05-17 18:14:43 +00004720- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4721 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004722
4723- Patch #1733960: Allow T_LONGLONG to accept ints.
4724
4725- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4726
Christian Heimes000a0742008-01-03 22:16:32 +00004727- Added a new API function ``PyImport_ImportModuleNoBlock``.
4728
Georg Brandl6caad7d2008-01-26 14:19:22 +00004729- Bug #1637022: Prefix AST symbols with _Py_.
4730
4731- Fix some leftovers from the conversion from int to Py_ssize_t
4732 (relevant to strings and sequences of more than 2**31 items).
4733
4734- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4735 outside of pystate.c and should not be necessary.
4736
Georg Brandl3ee81df2008-05-17 18:14:43 +00004737- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4738 absolute imports. In earlier versions they might have used relative
4739 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004740
Georg Brandl3ee81df2008-05-17 18:14:43 +00004741- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4742 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004743
Georg Brandl3ee81df2008-05-17 18:14:43 +00004744- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4745 macro so it can be used as an expression.

4750
Georg Brandl3ee81df2008-05-17 18:14:43 +00004751- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4752 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4753 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4754 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004755
Georg Brandl3ee81df2008-05-17 18:14:43 +00004756- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4757 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004769- Removed the macfs module. It had been deprecated since Python 2.5.
4770 This lead to the deprecation of macostools.touched() as it relied
4771 solely on macfs and was a no-op under OS X.
