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.

31 processing: any non-float non-integer argument is now converted to
32 an integer (if possible) using its __int__ method. Previously, only
33 small arguments were treated this way; larger arguments (those whose
34 __int__ was outside the range of a C long) would produce a TypeError.

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

1488What's New in Python 2.6.1
1489==========================
1490
1491*Release date: 04-Dec-2008*
1492
1493Core and Builtins
1494-----------------
1495
1496- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1497 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1498 instead of throwing a MemoryError.
1499
1500- Issue #4367: Python would segfault during compiling when the unicodedata
1501 module couldn't be imported and \N escapes were present.
1502
1503- Issue #4348: Some bytearray methods returned that didn't cause any change to
1504 the bytearray, returned the same bytearray instead of a copy.
1505
1506- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1507
1508- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1509
1510- Issue #4048: The parser module now correctly validates relative imports.
1511
1512- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1513 exec statement.
1514
1515- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1516 method does not return iterators for the 4th and 5th items.
1517
1518- Issue #4209: Enabling unicode_literals and the print_function in the same
1519 __future__ import didn't work.
1520
1521- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1522 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1523 really executed because I cannot move to such directory on win2k)
1524
1525- Issue #4069: When set.remove(element) is used with a set element, the element
1526 is temporarily replaced with an equivalent frozenset. But the eventual
1527 KeyError would always report the empty frozenset([]) as the missing key. Now
1528 it correctly refers to the initial element.
1529
1530- Fixed C99 style comments in several files. Python is now C89 compatible
1531 again.

1679
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001680- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1681 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1682 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1683 ``printf`` function, whereas PyString_FromFormat has an independent
1684 implementation and uses "%zd" on all platforms for size_t values.
1685 This makes a difference on win64, where ``printf`` needs "%Id" to display
1686 64bit values.

1692 object; previously an int would be returned for small values. the __long__
1693 method is allowed to return either an int or a long, but the behaviour of
1694 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001703 was correctly parsed but parsing of subsequent arguments failed.
1704
Vinay Sajip35e3b032008-09-01 14:33:59 +00001705- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001706 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1707 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1708 when given a tuple of classes as second argument, were looking up
1709 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1710 type object.
1711
Neal Norwitz18aa3882008-08-24 05:04:52 +00001712- Fix crashes on memory allocation failure found with failmalloc.

1852-----------------
1853
Guido van Rossumf8402962008-08-20 15:01:50 +00001854- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1855 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1856 extensions do not automatically benefit from the class attribute
1857 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1858 to their tp_flags field if they care. This is a backwards
1859 compatibility feature; in 3.0, all types will use the cache by
1860 default.
1861
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001862- Keyword arguments can now follow starred arguments. (``f(a, *args,

Georg Brandl1e13ea92008-08-11 09:07:59 +00001872- Issue #3537: Fix an assertion failure when an empty but presized dict
1873 object was stored in the freelist.
1874
Mark Dickinsonb6467572008-08-04 21:30:09 +00001875- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1876 ValueError consistently across platforms.
1877
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001878- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1879 (64bit Unix, for example), unichr() would truncate its argument and return
1880 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1881
Neal Norwitze7d8be82008-07-31 17:17:14 +00001882- Apply security patches from Apple.
1883
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001884- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1885 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1886
Antoine Pitrou92f82162008-07-25 22:22:08 +00001887- Issue #1819: function calls with several named parameters are now on
1888 average 35% faster (as measured by pybench).
1889
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001890- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1891 the python debugger steps into a class statement: the free variables (local
1892 variables defined in an outer scope) would be deleted from the outer scope.
1893
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001894- Issue #2620: Overflow checking when allocating or reallocating memory
1895 was not always being done properly in some python types and extension
1896 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1897 all been updated to perform better checks and places in the code that
1898 would previously leak memory on the error path when such an allocation
1899 failed have been fixed.

1908
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001909- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1910 version reported by these tools does not necessarily follow the python
1911 version numbering scheme, so the module is less strict when parsing it.
1912
Nick Coghlanf70385a2008-08-18 12:42:46 +00001913- Issue #2235: Added Py3k warnings for types which will become unhashable
1914 under the stricter __hash__ inheritance rules in 3.0. Several types
1915 which did not meet the rules for hash invariants and were already
1916 unhashable in 3.0 have now been explicitly flagged as unhashable in
1917 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1918 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1919
Brett Cannon88f801d2008-08-18 00:46:22 +00001920- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1921 imported into the module but exposed as part of the module's API.
1922

1943
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001944- Issue #2676: in the email package, content-type parsing was hanging on

1946 regular expression.
1947
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001948- Issue #3476: binary buffered reading through the new "io" library is now
1949 thread-safe.

Brett Cannonbf3157b2008-08-14 05:00:03 +00001951- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1952 since mimetools itself is deprecated. Because modules are cached, all
1953 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1954
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001955- Issue #3134: shutil referenced undefined WindowsError symbol.

Brett Cannon83e81842008-08-09 23:30:55 +00001960- Copied the implementation of reduce() to _functools.reduce() to have a
1961 version that did not raise a DeprecationWarning under -3.
1962
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001963- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1964 a MemoryError rather than silently stop the iteration.
1965
Guido van Rossum59ce9012008-08-09 14:55:34 +00001966- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1967 to _sre.compile() will now be rejected. This should not affect anybody
1968 since the re.compile() function never generates invalid re-bytecode.

Skip Montanaroa032bf42008-08-08 22:52:51 +00001970- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1971 upon first access it can be automatically initialized from the csv file if
1972 it wasn't initialized during instantiation.
1973
Brett Cannon3aa2a492008-08-06 22:28:09 +00001974- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1975 the reload() built-in has been removed.
1976
Brett Cannon7e30b672008-08-04 21:52:25 +00001977- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001978 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1986 raised an AttributeError.
1987
Benjamin Peterson01a24322008-07-28 23:35:27 +00001988- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001989 asking for a specific length. This problem only affected files opened
1990 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001991

2014
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002015- Issue #3394: zipfile.writestr sets external attributes when passed a
2016 file name rather than a ZipInfo instance, so files are extracted with
2017 mode 0600 rather than 000 under Unix.
2018
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002019- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2020 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002031- Issue #2235: the C API function PyObject_HashNotImplemented and its
2032 interaction with the tp_hash slot (added in 2.6b2) are now documented
2033
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002034- Issue #643841: The language reference now provides more detailed
2035 coverage of the lookup process for special methods. The disclaimers
2036 regarding lack of coverage of new-style classes have also been
2037 removed, since the coverage is now fairly reasonable.

2041================================
2042
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002043*Release date: 17-Jul-2008*
2044
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002045Core and Builtins
2046-----------------
2047
Georg Brandl3e483f62008-07-16 22:57:41 +00002048- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2049 its methods now allow for items objects that can be converted to
2050 an integer using operator.index().
2051
Mark Dickinson64b7e502008-07-16 09:40:03 +00002052- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2053 produced a ValueError instead of giving the correct float.
2054
Eric Smitha5fa5a22008-07-16 00:11:49 +00002055- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2056 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2057
Mark Dickinson7103aa42008-07-15 19:08:33 +00002058- Issue #3008: the float type has a new instance method 'float.hex'
2059 and a new class method 'float.fromhex' to convert floating-point
2060 numbers to and from hexadecimal strings, respectively.
2061
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002062- Issue #2235: __hash__ is once again inherited by default. To allow
2063 collections.Hashable to remain meaningful in the presence of the
2064 default hash implementation (object.__hash__), it is now possible
2065 to explicit block inheritance of hash by setting __hash__=None at
2066 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2067 level.
2068
Nick Coghlanb028f502008-07-13 14:52:36 +00002069- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2070 the parent module cannot be found while performing an absolute import.
2071 This means that an incorrectly defined __package__ attribute will
2072 now only prevent relative imports in that module rather than causing
2073 all imports from that module to fail.
2074
Nick Coghlan14ff9942008-07-08 14:21:42 +00002075- Issue #2517: Allow unicode messages in Exceptions again by correctly
2076 bypassing the instance dictionary when looking up __unicode__ on
2077 new-style classes.
2078
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002079- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2080 set to a custom object whose write() method happens to install
2081 another file in sys.stdout.
2082
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002083- Issue #3088: Corrected a race condition in classes derived from
2084 threading.local: the first member set by a thread could be saved in
2085 another thread's dictionary.
2086
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002087- Issue #3004: Minor change to slice.indices(): the start and stop
2088 arguments are now treated identically, making the behaviour easier
2089 to describe and understand. For example, slice(None, -10,
2090 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2091 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2092 10, -1).
2093
Georg Brandl278fc502008-07-19 12:46:12 +00002094- Issue #3219: Calling a function with repeated keyword arguments,
2095 f(a=2, a=23), would not cause a syntax error. This was a regression
2096 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002097
Georg Brandl278fc502008-07-19 12:46:12 +00002098- Issue #2862: Make int and float freelist management consistent with
2099 other freelists. Changes their CompactFreeList apis into
2100 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002105- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2106 api functions without holding the GIL, which could lead to a fatal
2107 error when they failed.
2108
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002109- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2118 ForkingPickler.register() to resolve conflict with ctypes.
2119
Vinay Sajip51e65192008-07-18 09:01:10 +00002120- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2123 a valid dlerror() message.
2124
Thomas Heller2bad6572008-07-15 17:19:50 +00002125- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2126 incomplete structure was created.
2127

2131
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002132- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002133
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002134- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2135 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002136 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002137 content-length. The problem had been corrected in the 2.4 branch, but never
2138 merged into trunk.
2139
Georg Brandle78fbcc2008-07-05 10:13:36 +00002140- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002151 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002152
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002153- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00002546 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002547
2548 This is controlled by the configure argument ``--with-universal-archs``:
2549
2550 - ``--with-universal-archs=all``: install 4-way universal
2551
2552 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2553
2554 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2555
2556 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002608- Issue #1631171: Re-implement the 'warnings' module in C (the
2609 original Python code has been kept as backup). This will allow for
2610 using the 'warning's machinery in such places as the parser where
2611 use of pure Python code is not possible. Both the ``showarning()``
2612 and ``formatwarning()`` gain an optional 'line' argument which is
2613 not called by default for backwards-compatibility reasons. Setting
2614 ``warnings.showwarning()`` to an implementation that lacks support
2615 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002678- Issue #2550: The approach used by client/server code for obtaining
2679 ports to listen on in network-oriented tests has been refined in an
2680 effort to facilitate running multiple instances of the entire
2681 regression test suite in parallel without issue.
2682 test_support.bind_port() has been fixed such that it will always
2683 return a unique port -- which wasn't always the case with the
2684 previous implementation, especially if socket options had been set
2685 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2686 new implementation of bind_port() will actually raise an exception
2687 if it is passed an AF_INET/SOCK_STREAM socket with either the
2688 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2689 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2690 the socket it's been passed. This currently only applies to
2691 Windows. This option prevents any other sockets from binding to the
2692 host/port we've bound to, thus removing the possibility of the
2693 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2694 when a second SOCK_STREAM socket binds and accepts to a host/port
2695 that's already been bound by another socket. The optional preferred
2696 port parameter to bind_port() has been removed. Under no
2697 circumstances should tests be hard coding ports!
2698
2699 test_support.find_unused_port() has also been introduced, which will
2700 pass a temporary socket object to bind_port() in order to obtain an
2701 unused port. The temporary socket object is then closed and
2702 deleted, and the port is returned. This method should only be used
2703 for obtaining an unused port in order to pass to an external program
2704 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2705 a parameter to a server-oriented class that doesn't give you direct
2706 access to the underlying socket used.
2707
2708 Finally, test_support.HOST has been introduced, which should be used
2709 for the host argument of any relevant socket calls (i.e. bind and
2710 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002711
2712 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002713 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002714 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2715 test_asynchat and test_socket_ssl.
2716
Georg Brandl3ee81df2008-05-17 18:14:43 +00002717 It is now possible for multiple instances of the regression test
2718 suite to run in parallel without issue.

2984Core and builtins
2985-----------------
2986
Fred Drakea8ee94b2008-03-01 02:45:07 +00002987- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002988 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002989
Georg Brandlad61bc82008-02-23 15:11:18 +00002990- Issue #2067: file.__exit__() now calls subclasses' close() method.
2991
2992- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002993
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002994- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002995 issue 215555 for a discussion.
2996
Eric Smitha73fbe72008-02-23 03:09:44 +00002997- Added the future_builtins module, which contains hex() and oct().
2998 These are the PEP 3127 version of these functions, designed to be
2999 compatible with the hex() and oct() builtins from Python 3.0. They
3000 differ slightly in their output formats from the existing, unchanged
3001 Python 2.6 builtins. The expected usage of the future_builtins
3002 module is:
3003 from future_builtins import hex, oct
3004
Eric Smith7ef40bf2008-02-20 23:34:22 +00003005- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3006 exponents for exponents with absolute value < 100. Follows C99
3007 standard. This is a change on Windows, which would use 3 digits.
3008 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3009 so that any alterations it does to the resulting string will be
3010 available in stringlib/formatter.h (for float.__format__).
3011
Eric Smith5a3c1352008-02-19 13:21:56 +00003012- Implemented PEP 3101, Advanced String Formatting. This adds a new
3013 builtin format(); a format() method for str and unicode; a
3014 __format__() method to object, str, unicode, int, long, float, and
3015 datetime; the class string.Formatter; and the C API
3016 PyObject_Format().
3017
Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Fixed several potential crashes, all caused by specially crafted
3019 __del__ methods exploiting objects in temporarily inconsistent
3020 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003021
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003022- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003023 prevent a possible crash: an Abstract Base Class would try to access
3024 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003025
Georg Brandl3ee81df2008-05-17 18:14:43 +00003026- Fixed repr() and str() of complex numbers with infinity or nan as
3027 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003028
Georg Brandl3ee81df2008-05-17 18:14:43 +00003029- Clear all free lists during a gc.collect() of the highest generation
3030 in order to allow pymalloc to free more arenas. Python may give back
3031 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003032
Georg Brandl3ee81df2008-05-17 18:14:43 +00003033- Issue #2045: Fix an infinite recursion triggered when printing a
3034 subclass of collections.defaultdict, if its default_factory is set
3035 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003036
Christian Heimesf75dbef2008-02-08 00:11:31 +00003037- Fixed a minor memory leak in dictobject.c. The content of the free
3038 list was not freed on interpreter shutdown.
3039
Georg Brandl5a7eca12010-03-21 19:29:04 +00003040- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003041 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003042
Georg Brandl3ee81df2008-05-17 18:14:43 +00003043- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3044 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003045 to compact the internal free lists of pre-allocted ints and floats.
3046
Georg Brandl3ee81df2008-05-17 18:14:43 +00003047- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3048 calls. Python expected the return type int but the fork familie
3049 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003050
Georg Brandl3ee81df2008-05-17 18:14:43 +00003051- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3052 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003053
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3055 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3058 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003059
Georg Brandl3ee81df2008-05-17 18:14:43 +00003060- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3061 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003062
Georg Brandl3ee81df2008-05-17 18:14:43 +00003063- Patch #1473257: generator objects gain a gi_code attribute. This is
3064 the same object as the func_code attribute of the function that
3065 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003066
Georg Brandl3ee81df2008-05-17 18:14:43 +00003067- Issue #1920: "while 0" statements were completely removed by the
3068 compiler, even in the presence of an "else" clause, which is
3069 supposed to be run when the condition is false. Now the compiler
3070 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003071
Guido van Rossumeead05f2008-01-24 18:21:02 +00003072- A few crashers fixed: weakref_in_del.py (issue #1377858);
3073 loosing_dict_ref.py (issue #1303614, test67.py);
3074 borrowed_ref_[34].py (not in tracker).
3075
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003076- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003077 suppressed while an extension is loaded by calling SetErrorMode in
3078 dynload_win.c. The error is still reported properly.
3079
Georg Brandl3ee81df2008-05-17 18:14:43 +00003080- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003081 several extension methods and modules do not work without unicode
3082 support.
3083
Georg Brandl26543b12008-01-21 18:36:51 +00003084- Issue #1882: when compiling code from a string, encoding cookies in the
3085 second line of code were not always recognized correctly.
3086
Georg Brandl14404b62008-01-19 19:27:05 +00003087- Issue #1679: "0x" was taken as a valid integer literal.
3088
Georg Brandl6caad7d2008-01-26 14:19:22 +00003089- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003090 added.
3091
Christian Heimesc94e2b52008-01-14 04:13:37 +00003092- sys.float_info / PyFloat_GetInfo: The floating point information
3093 object was converted from a dict to a specialized structseq object.
3094
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095- Patch #1816: Added sys.flags structseq. It exposes the status of
3096 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003097
Georg Brandl3ee81df2008-05-17 18:14:43 +00003098- Objects/structseq.c: Implemented new structseq representation. The
3099 patch makes structseqs (e.g. the return value of os.stat) more
3100 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003101
Georg Brandl3ee81df2008-05-17 18:14:43 +00003102- Patch #1700288: added a type attribute cache that caches method
3103 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003104
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003105- Bug #1776: __import__() no longer accepts filenames on any platform.
3106 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003107
Georg Brandlaed6c662008-01-07 17:25:53 +00003108- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3111 envvar and sys.dont_write_bytecode attribute. All these can be set
3112 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003113
Georg Brandl3ee81df2008-05-17 18:14:43 +00003114- Improve some exception messages when Windows fails to load an
3115 extension module. Now we get for example '%1 is not a valid Win32
3116 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003117
Georg Brandl3ee81df2008-05-17 18:14:43 +00003118- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003120- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3121 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003122
Christian Heimes0a8143f2007-12-18 23:22:54 +00003123- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124 and INF. float("nan"), float("inf") and float("-inf") now work on
3125 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003126
Georg Brandl3ee81df2008-05-17 18:14:43 +00003127- Compiler now generates simpler and faster code for dictionary
3128 literals. The oparg for BUILD_MAP now indicates an estimated
3129 dictionary size. There is a new opcode, STORE_MAP, for adding
3130 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003131
Georg Brandl3ee81df2008-05-17 18:14:43 +00003132- Issue #1638: %zd configure test fails on Linux.

3145 __package__ attribute.
3146
Georg Brandl3ee81df2008-05-17 18:14:43 +00003147- Issue #1402: Fix a crash on exit, when another thread is still
3148 running, and if the deallocation of its frames somehow calls the
3149 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003150

3160 file can now be directly executed by passing their name to the
3161 interpreter. The directory/zipfile is automatically inserted as the
3162 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003163
Georg Brandl3ee81df2008-05-17 18:14:43 +00003164- Issue #1265: Fix a problem with sys.settrace, if the tracing
3165 function uses a generator expression when at the same time the
3166 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003167
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003168- sets and frozensets now have an isdisjoint() method.
3169
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003170- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00003172- Fix warnings found by the new version of the Coverity checker.
3173
Georg Brandl5a7eca12010-03-21 19:29:04 +00003174- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003175 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3176 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003177
Georg Brandl3ee81df2008-05-17 18:14:43 +00003178- Issue #1686386: Tuple's tp_repr did not take into account the
3179 possibility of having a self-referential tuple, which is possible
3180 from C code. Nor did object's tp_str consider that a type's tp_str
3181 could do something that could lead to an inifinite recursion.
3182 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3183 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003184
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Issue #1164: It was possible to trigger deadlock when using the
3186 'print' statement to write to a file since the GIL was not released
3187 as needed. Now PyObject_Print() does the right thing along with
3188 various tp_print implementations of the built-in types and those in
3189 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003190
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191- Issue #1147: Exceptions were directly allowing string exceptions in
3192 their throw() method even though string exceptions no longer
3193 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00003198- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003199 PyObject_Call() never calling back out to Python code to trigger
3200 recursion depth updates/checks. Required the creation of a static
3201 RuntimeError instance in case normalizing an exception put the
3202 recursion check value past its limit. Fixes crashers
3203 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003204

Neal Norwitz0ac60192007-05-27 04:08:54 +00003218- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003219 __*__ attributes. (Some already existed, e.g., __doc__ and
3220 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003221
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003222- Add -3 option to the interpreter to warn about features that are
3223 deprecated and will be changed/removed in Python 3.0.
3224
Georg Brandl2134e752007-05-21 20:34:16 +00003225- Patch #1686487: you can now pass any mapping after '**' in function
3226 calls.
3227
Collin Winter62903052007-05-18 23:11:24 +00003228- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003229 "except E as target:". This is to provide forwards compatibility
3230 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003231
Brett Cannon229cee22007-05-05 01:34:02 +00003232- Deprecate BaseException.message as per PEP 352.
3233
Georg Brandl3ee81df2008-05-17 18:14:43 +00003234- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003235 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003236
Vinay Sajip8549ce32007-05-06 17:53:37 +00003237- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003238 setting a plain string, ie don't expand to single letter identifiers.
3239
Raymond Hettinger13936692007-04-11 18:40:58 +00003240- Request #1191699: Slices can now be pickled.
3241
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003242- Request #1193128: str.translate() now allows a None argument for
3243 translations that only remove characters without re-mapping the
3244 remaining characters.
3245
Georg Brandl5cb76c12007-03-21 09:00:39 +00003246- Patch #1682205: a TypeError while unpacking an iterable is no longer
3247 masked by a generic one with the message "unpack non-sequence".
3248

3250
Guido van Rossum143b5642007-03-23 04:58:42 +00003251- Bug #1683368: The object.__init__() and object.__new__() methods are
3252 now stricter in rejecting excess arguments. The only time when
3253 either allows excess arguments is when it is not overridden and the
3254 other one is. For backwards compatibility, when both are
3255 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003256 warning later). Also, type.__init__() insists on the same signature
3257 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003258
Georg Brandl3ee81df2008-05-17 18:14:43 +00003259- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3260 object to complex using its __complex__() method before falling back
3261 to the __float__() method. Therefore, the functions in the cmath
3262 module now can operate on objects that define a __complex__()
3263 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003264
Georg Brandl3ee81df2008-05-17 18:14:43 +00003265- Patch #1623563: allow __class__ assignment for classes with
3266 __slots__. The old and the new class are still required to have the
3267 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003268

3273 ``object.__reduce_ex__()`` is called with an object that is faking
3274 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003275

3280
Georg Brandl7b9c5552007-03-12 14:30:05 +00003281- Bug #1678647: write a newline after printing an exception in any
3282 case, even when converting the value to a string failed.
3283
Georg Brandl871f1bc2007-03-12 13:17:36 +00003284- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003285 its argument, if it exists. If not, it will work like before. This
3286 allows customizing the output of dir() in the presence of a
3287 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003288
Collin Winter276887b2007-03-12 16:11:39 +00003289- Patch #922167: Python no longer segfaults when faced with infinitely
3290 self-recursive reload() calls (as reported by bug #742342).
3291

Georg Brandl3ee81df2008-05-17 18:14:43 +00003295- Patch #1491866: change the complex() constructor to allow
3296 parthensized forms. This means complex(repr(x)) now works instead of
3297 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003298
Georg Brandlaa2321b2007-03-07 00:40:28 +00003299- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003300 makes the filenames the warning module prints much more sensible
3301 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003302
Georg Brandl49aafc92007-03-07 00:34:46 +00003303- Variant of patch #697613: don't exit the interpreter on a SystemExit
3304 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003305 variable is given, but break into the interactive interpreter just
3306 like on other exceptions or normal program exit.

3312 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003313
Georg Brandl0fca97a2007-03-05 22:28:08 +00003314- Patch #1674228: when assigning a slice (old-style), check for the
3315 sq_ass_slice instead of the sq_slice slot.
3316
Georg Brandl3ee81df2008-05-17 18:14:43 +00003317- When printing an unraisable error, don't print exceptions. before
3318 the name. This duplicates the behavior whening normally printing
3319 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003320
Georg Brandl3ee81df2008-05-17 18:14:43 +00003321- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003327- Bug #1377858: Fix the segfaulting of the interpreter when an object
3328 created a weakref on itself during a __del__ call for new-style
3329 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003943- unittest now verifies more of its assumptions. In particular,
3944 TestCase and TestSuite subclasses (not instances) are no longer
3945 accepted in TestSuite.addTest(). This should cause no
3946 incompatibility since it never made sense with ordinary subclasses
3947 -- the failure just occurred later, with a more cumbersome
3948 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004229- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4230 with RFC 3207 and forgets any knowledge obtained from the server not
4231 obtained from the TLS negotiation itself. Patch contributed by Bill
4232 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004233
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004235 that the SMTP.starttls() caller no longer needs to call ehlo()
4236 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004237 does not claim to support starttls. Adds the
4238 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4319 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4320 silently miscode subclasses of those types. Now, it raises a
4321 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004322

Georg Brandl3ee81df2008-05-17 18:14:43 +00004337 time so that opening a database previously created with the DB_DUP
4338 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4339 opens. Specifically: dictionary assignment to a DB object will
4340 replace all values for a given key when the database allows
4341 duplicate values. DB users should use DB.put(k, v) when they want
4342 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004343

4349 characters with ASCII value less than 32. Also, it correctly quotes
4350 dots only if they occur on a single line, as opposed to the previous
4351 behavior of quoting dots if they are the second character of any
4352 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004353

Georg Brandl3ee81df2008-05-17 18:14:43 +00004677- Unified naming convention for free lists and their limits. All free
4678 lists in Object/ are named ``free_list``, the counter ``numfree``
4679 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4680 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004681
Georg Brandl3ee81df2008-05-17 18:14:43 +00004682- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4683 to ``PyTuple_SetItem``, it can be used to populate a brand new
4684 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004685
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004686- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004687
Georg Brandl3ee81df2008-05-17 18:14:43 +00004688- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4689 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4690 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004691
4692- Patch #1720595: add T_BOOL to the range of structmember types.
4693
4694- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4695 ``PyFloat_GetInfo()`` to the float API.
4696
Georg Brandl3ee81df2008-05-17 18:14:43 +00004697- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4698 of w# format code incorrectly truncated the length to an int, even
4699 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4700 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004701
Georg Brandl3ee81df2008-05-17 18:14:43 +00004702- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4703 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004704
Georg Brandl3ee81df2008-05-17 18:14:43 +00004705- PEP 3123: Provide forward compatibility with Python 3.0, while
4706 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4707 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004708
Georg Brandl3ee81df2008-05-17 18:14:43 +00004709- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4710 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004711
4712- Patch #1733960: Allow T_LONGLONG to accept ints.
4713
4714- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4715
Christian Heimes000a0742008-01-03 22:16:32 +00004716- Added a new API function ``PyImport_ImportModuleNoBlock``.
4717
Georg Brandl6caad7d2008-01-26 14:19:22 +00004718- Bug #1637022: Prefix AST symbols with _Py_.
4719
4720- Fix some leftovers from the conversion from int to Py_ssize_t
4721 (relevant to strings and sequences of more than 2**31 items).
4722
4723- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4724 outside of pystate.c and should not be necessary.
4725
Georg Brandl3ee81df2008-05-17 18:14:43 +00004726- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4727 absolute imports. In earlier versions they might have used relative
4728 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004729
Georg Brandl3ee81df2008-05-17 18:14:43 +00004730- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4731 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004732
Georg Brandl3ee81df2008-05-17 18:14:43 +00004733- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4734 macro so it can be used as an expression.

4739
Georg Brandl3ee81df2008-05-17 18:14:43 +00004740- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4741 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4742 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4743 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004744
Georg Brandl3ee81df2008-05-17 18:14:43 +00004745- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4746 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00004756- buildtools now raises a DeprecationWarning.
4757
Georg Brandl3ee81df2008-05-17 18:14:43 +00004758- Removed the macfs module. It had been deprecated since Python 2.5.
4759 This lead to the deprecation of macostools.touched() as it relied
4760 solely on macfs and was a no-op under OS X.
