Antoine Pitrou4595e512010-06-11 21:48:02 +000015- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
16 the interpreter with characters outside the Basic Multilingual Plane
17 (higher than 0x10000).
18
Mark Dickinson80068da2010-06-05 11:59:41 +000019- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsonb671c292010-06-05 12:15:35 +000020 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
21 arises from the "Overriding __eq__ blocks inheritance ..." warning
22 when turned into an exception: in this case the exception simply
23 gets ignored.
Mark Dickinson80068da2010-06-05 11:59:41 +000024
Benjamin Peterson85633362010-06-08 14:58:25 +000025- In the unicode/str.format(), raise a ValueError when indexes to arguments are

36
Mark Dickinsone02c9d22010-05-07 13:23:18 +000037- Issue #1533: fix inconsistency in range function argument
38 processing: any non-float non-integer argument is now converted to
39 an integer (if possible) using its __int__ method. Previously, only
40 small arguments were treated this way; larger arguments (those whose
41 __int__ was outside the range of a C long) would produce a TypeError.
42

68 sys.path. This helps fix `CVE-2008-5983
69 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

207 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

1317 do an explicit seek to the end of file (so that e.g. tell() returns the

1354 302 conformant loader) will now work correctly in most cases (they

1515What's New in Python 2.6.1
1516==========================
1517
1518*Release date: 04-Dec-2008*
1519
1520Core and Builtins
1521-----------------
1522
1523- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1524 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1525 instead of throwing a MemoryError.
1526
1527- Issue #4367: Python would segfault during compiling when the unicodedata
1528 module couldn't be imported and \N escapes were present.
1529
1530- Issue #4348: Some bytearray methods returned that didn't cause any change to
1531 the bytearray, returned the same bytearray instead of a copy.
1532
1533- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1534
1535- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1536
1537- Issue #4048: The parser module now correctly validates relative imports.
1538
1539- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1540 exec statement.
1541
1542- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1543 method does not return iterators for the 4th and 5th items.
1544
1545- Issue #4209: Enabling unicode_literals and the print_function in the same
1546 __future__ import didn't work.
1547
1548- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1549 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1550 really executed because I cannot move to such directory on win2k)
1551
1552- Issue #4069: When set.remove(element) is used with a set element, the element
1553 is temporarily replaced with an equivalent frozenset. But the eventual
1554 KeyError would always report the empty frozenset([]) as the missing key. Now
1555 it correctly refers to the initial element.
1556
1557- Fixed C99 style comments in several files. Python is now C89 compatible
1558 again.
1559
1560Library
1561-------

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001705- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1706
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001707- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1708 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1709 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1710 ``printf`` function, whereas PyString_FromFormat has an independent
1711 implementation and uses "%zd" on all platforms for size_t values.
1712 This makes a difference on win64, where ``printf`` needs "%Id" to display
1713 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001715- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1719 object; previously an int would be returned for small values. the __long__

1721 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001730 was correctly parsed but parsing of subsequent arguments failed.
1731
Vinay Sajip35e3b032008-09-01 14:33:59 +00001732- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001733 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1734 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1735 when given a tuple of classes as second argument, were looking up
1736 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1737 type object.
1738
Neal Norwitz18aa3882008-08-24 05:04:52 +00001739- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001873What's New in Python 2.6 beta 3?
1874================================
1875
Barry Warsaw07a4a382008-08-21 01:15:08 +00001876*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001877
1878Core and Builtins
1879-----------------
1880
Guido van Rossumf8402962008-08-20 15:01:50 +00001881- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1882 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1883 extensions do not automatically benefit from the class attribute
1884 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1885 to their tp_flags field if they care. This is a backwards
1886 compatibility feature; in 3.0, all types will use the cache by
1887 default.
1888
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001889- Keyword arguments can now follow starred arguments. (``f(a, *args,
1890 keyword=23)`` is now valid syntax.)
1891
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001892- ctypes function pointers that are COM methods have a boolean True
1893 value again.
1894
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001895- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1896 by denying s# to parse objects that have a releasebuffer procedure,
1897 and introducing s*.
1898
Georg Brandl1e13ea92008-08-11 09:07:59 +00001899- Issue #3537: Fix an assertion failure when an empty but presized dict
1900 object was stored in the freelist.
1901
Mark Dickinsonb6467572008-08-04 21:30:09 +00001902- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1903 ValueError consistently across platforms.
1904
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001905- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1906 (64bit Unix, for example), unichr() would truncate its argument and return
1907 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1908
Neal Norwitze7d8be82008-07-31 17:17:14 +00001909- Apply security patches from Apple.
1910
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001911- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1912 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1913
Antoine Pitrou92f82162008-07-25 22:22:08 +00001914- Issue #1819: function calls with several named parameters are now on
1915 average 35% faster (as measured by pybench).
1916
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001917- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1918 the python debugger steps into a class statement: the free variables (local
1919 variables defined in an outer scope) would be deleted from the outer scope.
1920
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001921- Issue #2620: Overflow checking when allocating or reallocating memory
1922 was not always being done properly in some python types and extension
1923 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1924 all been updated to perform better checks and places in the code that
1925 would previously leak memory on the error path when such an allocation
1926 failed have been fixed.
1927
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001928Library
1929-------
1930
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001931- Issue #3612: Added some missing basic types in ctypes.wintypes.
1932
Benjamin Petersone977ad42008-08-20 01:42:01 +00001933- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1934 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1935
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001936- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1937 version reported by these tools does not necessarily follow the python
1938 version numbering scheme, so the module is less strict when parsing it.
1939
Nick Coghlanf70385a2008-08-18 12:42:46 +00001940- Issue #2235: Added Py3k warnings for types which will become unhashable
1941 under the stricter __hash__ inheritance rules in 3.0. Several types
1942 which did not meet the rules for hash invariants and were already
1943 unhashable in 3.0 have now been explicitly flagged as unhashable in
1944 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1945 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1946
Brett Cannon88f801d2008-08-18 00:46:22 +00001947- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1948 imported into the module but exposed as part of the module's API.
1949
Brett Cannon7b96f072008-08-18 00:41:11 +00001950- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1951
Brett Cannon46225e72008-08-18 00:36:52 +00001952- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1953
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001954- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1955
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001956- Issue #3575: Incremental decoder's decode function now takes bytearray
1957 by using 's*' instead of 't#'.
1958
Jesus Cea585ad8a2009-07-02 15:37:21 +00001959- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001960 fails unicode conversion on 2nd parameter. (windows only)
1961
Facundo Batista94f243a2008-08-17 03:38:39 +00001962- Issue 2464. urllib2 now supports a malformation in the URL received
1963 in a redirect.
1964
Brett Cannonabe423e2008-08-16 21:47:07 +00001965- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001966 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001967
Facundo Batistaeb90b782008-08-16 14:44:07 +00001968- Issue #2776: fixed small issue when handling an URL with double slash
1969 after a 302 response in the case of not going through a proxy.
1970
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001971- Issue #2676: in the email package, content-type parsing was hanging on
1972 pathological input because of quadratic or exponential behaviour of a
1973 regular expression.
1974
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001975- Issue #3476: binary buffered reading through the new "io" library is now
1976 thread-safe.
1977
Brett Cannonbf3157b2008-08-14 05:00:03 +00001978- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1979 since mimetools itself is deprecated. Because modules are cached, all
1980 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1981
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001982- Issue #3134: shutil referenced undefined WindowsError symbol.
1983
Robert Schuppenies14646332008-08-10 11:01:53 +00001984- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1985 menu entries were not deleted.
1986
Brett Cannon83e81842008-08-09 23:30:55 +00001987- Copied the implementation of reduce() to _functools.reduce() to have a
1988 version that did not raise a DeprecationWarning under -3.
1989
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001990- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1991 a MemoryError rather than silently stop the iteration.
1992
Guido van Rossum59ce9012008-08-09 14:55:34 +00001993- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1994 to _sre.compile() will now be rejected. This should not affect anybody
1995 since the re.compile() function never generates invalid re-bytecode.
1996
Skip Montanaroa032bf42008-08-08 22:52:51 +00001997- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1998 upon first access it can be automatically initialized from the csv file if
1999 it wasn't initialized during instantiation.
2000
Brett Cannon3aa2a492008-08-06 22:28:09 +00002001- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2002 the reload() built-in has been removed.
2003
Brett Cannon7e30b672008-08-04 21:52:25 +00002004- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002005 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00002006 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
2007 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2008 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2009 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2010 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002011
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002012- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2013 raised an AttributeError.
2014
Benjamin Peterson01a24322008-07-28 23:35:27 +00002015- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002016 asking for a specific length. This problem only affected files opened
2017 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002018
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002019- Issue #3449: Update decimal module to use most recent specification
2020 (v. 1.68) and tests (v. 2.58) from IBM.
2021
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002022- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
2023
Raymond Hettinger8c664e82008-07-25 18:43:33 +00002024- Issue 1592: Improve error reporting when operations are attempted
2025 on a closed shelf.

2030
2031- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2032 invalid arguments.
2033
2034- Issue #3302: Fix several crashes when calling locale's gettext functions
2035 with None arguments.
2036
2037- Issue #3389: Allow resolving dotted names for handlers in logging
2038 configuration files.
2039
2040- Deprecate the sunaudio module for removal in Python 3.0.
2041
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002042- Issue #3394: zipfile.writestr sets external attributes when passed a
2043 file name rather than a ZipInfo instance, so files are extracted with
2044 mode 0600 rather than 000 under Unix.
2045
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002046- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2047 argument in python 2.5, this broke code that subclassed Popen to include its
2048 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2056-------------
2057
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002058- Issue #2235: the C API function PyObject_HashNotImplemented and its
2059 interaction with the tp_hash slot (added in 2.6b2) are now documented
2060
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002061- Issue #643841: The language reference now provides more detailed
2062 coverage of the lookup process for special methods. The disclaimers
2063 regarding lack of coverage of new-style classes have also been
2064 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002067What's New in Python 2.6 beta 2?
2068================================
2069
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002070*Release date: 17-Jul-2008*
2071
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002072Core and Builtins
2073-----------------
2074
Georg Brandl3e483f62008-07-16 22:57:41 +00002075- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2076 its methods now allow for items objects that can be converted to
2077 an integer using operator.index().
2078
Mark Dickinson64b7e502008-07-16 09:40:03 +00002079- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2080 produced a ValueError instead of giving the correct float.
2081
Eric Smitha5fa5a22008-07-16 00:11:49 +00002082- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2083 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2084
Mark Dickinson7103aa42008-07-15 19:08:33 +00002085- Issue #3008: the float type has a new instance method 'float.hex'
2086 and a new class method 'float.fromhex' to convert floating-point
2087 numbers to and from hexadecimal strings, respectively.
2088
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002089- Issue #2235: __hash__ is once again inherited by default. To allow
2090 collections.Hashable to remain meaningful in the presence of the
2091 default hash implementation (object.__hash__), it is now possible
2092 to explicit block inheritance of hash by setting __hash__=None at
2093 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2094 level.
2095
Nick Coghlanb028f502008-07-13 14:52:36 +00002096- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2097 the parent module cannot be found while performing an absolute import.
2098 This means that an incorrectly defined __package__ attribute will
2099 now only prevent relative imports in that module rather than causing
2100 all imports from that module to fail.
2101
Nick Coghlan14ff9942008-07-08 14:21:42 +00002102- Issue #2517: Allow unicode messages in Exceptions again by correctly
2103 bypassing the instance dictionary when looking up __unicode__ on
2104 new-style classes.
2105
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002106- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2107 set to a custom object whose write() method happens to install
2108 another file in sys.stdout.
2109
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002110- Issue #3088: Corrected a race condition in classes derived from
2111 threading.local: the first member set by a thread could be saved in
2112 another thread's dictionary.
2113
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002114- Issue #3004: Minor change to slice.indices(): the start and stop
2115 arguments are now treated identically, making the behaviour easier
2116 to describe and understand. For example, slice(None, -10,
2117 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2118 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2119 10, -1).
2120
Georg Brandl278fc502008-07-19 12:46:12 +00002121- Issue #3219: Calling a function with repeated keyword arguments,
2122 f(a=2, a=23), would not cause a syntax error. This was a regression
2123 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002124
Georg Brandl278fc502008-07-19 12:46:12 +00002125- Issue #2862: Make int and float freelist management consistent with
2126 other freelists. Changes their CompactFreeList apis into
2127 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002128

2131
Thomas Heller57adf222008-08-14 19:10:48 +00002132- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2133 api functions without holding the GIL, which could lead to a fatal
2134 error when they failed.
2135
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002136- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002144- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2145 ForkingPickler.register() to resolve conflict with ctypes.
2146
Vinay Sajip51e65192008-07-18 09:01:10 +00002147- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2150 a valid dlerror() message.
2151
Thomas Heller2bad6572008-07-15 17:19:50 +00002152- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2153 incomplete structure was created.
2154
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002155- Issue #3339: dummy_thread.acquire() should not return None.
2156
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002157- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2158

2570
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002571- On MacOS X it is now possible to install the framework in 64-bit
2572 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002573 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002574
2575 This is controlled by the configure argument ``--with-universal-archs``:
2576
2577 - ``--with-universal-archs=all``: install 4-way universal
2578
2579 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2580
2581 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2582
2583 This option should be used in combination with ``--enable-universalsdk=``.
2584
2585 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2622 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00002623
Christian Heimese74c8f22008-04-19 02:23:57 +00002624- Added kill, terminate and send_signal(sig) to subprocess.Popen.
2625
Georg Brandl3ee81df2008-05-17 18:14:43 +00002626- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
2627 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00002628
Georg Brandl3ee81df2008-05-17 18:14:43 +00002629- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00002635- Issue #1631171: Re-implement the 'warnings' module in C (the
2636 original Python code has been kept as backup). This will allow for
2637 using the 'warning's machinery in such places as the parser where
2638 use of pure Python code is not possible. Both the ``showarning()``
2639 and ``formatwarning()`` gain an optional 'line' argument which is
2640 not called by default for backwards-compatibility reasons. Setting
2641 ``warnings.showwarning()`` to an implementation that lacks support
2642 for the ``line`` argument will raise a DeprecationWarning.

Thomas Hellerbf027c42008-04-24 18:14:19 +00002665 reference to themselves.
2666
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002667- The getpass module has been improved on Unix. It now uses /dev/tty
2668 by default and uses stderr instead of stdout. A GetPassWarning is
2669 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002670

Georg Brandl3ee81df2008-05-17 18:14:43 +00002684- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002685 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002705- Issue #2550: The approach used by client/server code for obtaining
2706 ports to listen on in network-oriented tests has been refined in an
2707 effort to facilitate running multiple instances of the entire
2708 regression test suite in parallel without issue.
2709 test_support.bind_port() has been fixed such that it will always
2710 return a unique port -- which wasn't always the case with the
2711 previous implementation, especially if socket options had been set
2712 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2713 new implementation of bind_port() will actually raise an exception
2714 if it is passed an AF_INET/SOCK_STREAM socket with either the
2715 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2716 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2717 the socket it's been passed. This currently only applies to
2718 Windows. This option prevents any other sockets from binding to the
2719 host/port we've bound to, thus removing the possibility of the
2720 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2721 when a second SOCK_STREAM socket binds and accepts to a host/port
2722 that's already been bound by another socket. The optional preferred
2723 port parameter to bind_port() has been removed. Under no
2724 circumstances should tests be hard coding ports!
2725
2726 test_support.find_unused_port() has also been introduced, which will
2727 pass a temporary socket object to bind_port() in order to obtain an
2728 unused port. The temporary socket object is then closed and
2729 deleted, and the port is returned. This method should only be used
2730 for obtaining an unused port in order to pass to an external program
2731 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2732 a parameter to a server-oriented class that doesn't give you direct
2733 access to the underlying socket used.
2734
2735 Finally, test_support.HOST has been introduced, which should be used
2736 for the host argument of any relevant socket calls (i.e. bind and
2737 connect).

3011Core and builtins
3012-----------------
3013
Fred Drakea8ee94b2008-03-01 02:45:07 +00003014- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003015 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003016
Georg Brandlad61bc82008-02-23 15:11:18 +00003017- Issue #2067: file.__exit__() now calls subclasses' close() method.
3018
3019- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003020
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003021- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003022 issue 215555 for a discussion.
3023
Eric Smitha73fbe72008-02-23 03:09:44 +00003024- Added the future_builtins module, which contains hex() and oct().
3025 These are the PEP 3127 version of these functions, designed to be
3026 compatible with the hex() and oct() builtins from Python 3.0. They
3027 differ slightly in their output formats from the existing, unchanged
3028 Python 2.6 builtins. The expected usage of the future_builtins
3029 module is:
3030 from future_builtins import hex, oct
3031
Eric Smith7ef40bf2008-02-20 23:34:22 +00003032- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3033 exponents for exponents with absolute value < 100. Follows C99
3034 standard. This is a change on Windows, which would use 3 digits.
3035 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3036 so that any alterations it does to the resulting string will be
3037 available in stringlib/formatter.h (for float.__format__).
3038
Eric Smith5a3c1352008-02-19 13:21:56 +00003039- Implemented PEP 3101, Advanced String Formatting. This adds a new
3040 builtin format(); a format() method for str and unicode; a
3041 __format__() method to object, str, unicode, int, long, float, and
3042 datetime; the class string.Formatter; and the C API
3043 PyObject_Format().
3044
Georg Brandl3ee81df2008-05-17 18:14:43 +00003045- Fixed several potential crashes, all caused by specially crafted
3046 __del__ methods exploiting objects in temporarily inconsistent
3047 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003048
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003049- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050 prevent a possible crash: an Abstract Base Class would try to access
3051 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003052
Georg Brandl3ee81df2008-05-17 18:14:43 +00003053- Fixed repr() and str() of complex numbers with infinity or nan as
3054 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003055
Georg Brandl3ee81df2008-05-17 18:14:43 +00003056- Clear all free lists during a gc.collect() of the highest generation
3057 in order to allow pymalloc to free more arenas. Python may give back
3058 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003059
Georg Brandl3ee81df2008-05-17 18:14:43 +00003060- Issue #2045: Fix an infinite recursion triggered when printing a
3061 subclass of collections.defaultdict, if its default_factory is set
3062 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003063
Christian Heimesf75dbef2008-02-08 00:11:31 +00003064- Fixed a minor memory leak in dictobject.c. The content of the free
3065 list was not freed on interpreter shutdown.
3066
Georg Brandl5a7eca12010-03-21 19:29:04 +00003067- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003068 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003069
Georg Brandl3ee81df2008-05-17 18:14:43 +00003070- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3071 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003072 to compact the internal free lists of pre-allocted ints and floats.
3073
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3075 calls. Python expected the return type int but the fork familie
3076 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003077
Georg Brandl3ee81df2008-05-17 18:14:43 +00003078- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3079 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003080
Georg Brandl3ee81df2008-05-17 18:14:43 +00003081- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3082 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003083
Georg Brandl3ee81df2008-05-17 18:14:43 +00003084- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3085 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3088 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003089
Georg Brandl3ee81df2008-05-17 18:14:43 +00003090- Patch #1473257: generator objects gain a gi_code attribute. This is
3091 the same object as the func_code attribute of the function that
3092 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003093
Georg Brandl3ee81df2008-05-17 18:14:43 +00003094- Issue #1920: "while 0" statements were completely removed by the
3095 compiler, even in the presence of an "else" clause, which is
3096 supposed to be run when the condition is false. Now the compiler
3097 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003098
Guido van Rossumeead05f2008-01-24 18:21:02 +00003099- A few crashers fixed: weakref_in_del.py (issue #1377858);
3100 loosing_dict_ref.py (issue #1303614, test67.py);
3101 borrowed_ref_[34].py (not in tracker).
3102
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003103- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003104 suppressed while an extension is loaded by calling SetErrorMode in
3105 dynload_win.c. The error is still reported properly.
3106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003108 several extension methods and modules do not work without unicode
3109 support.
3110
Georg Brandl26543b12008-01-21 18:36:51 +00003111- Issue #1882: when compiling code from a string, encoding cookies in the
3112 second line of code were not always recognized correctly.
3113
Georg Brandl14404b62008-01-19 19:27:05 +00003114- Issue #1679: "0x" was taken as a valid integer literal.
3115
Georg Brandl6caad7d2008-01-26 14:19:22 +00003116- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003117 added.
3118
Christian Heimesc94e2b52008-01-14 04:13:37 +00003119- sys.float_info / PyFloat_GetInfo: The floating point information
3120 object was converted from a dict to a specialized structseq object.
3121
Georg Brandl3ee81df2008-05-17 18:14:43 +00003122- Patch #1816: Added sys.flags structseq. It exposes the status of
3123 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003124
Georg Brandl3ee81df2008-05-17 18:14:43 +00003125- Objects/structseq.c: Implemented new structseq representation. The
3126 patch makes structseqs (e.g. the return value of os.stat) more
3127 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003128
Georg Brandl3ee81df2008-05-17 18:14:43 +00003129- Patch #1700288: added a type attribute cache that caches method
3130 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003131
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003132- Bug #1776: __import__() no longer accepts filenames on any platform.
3133 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003134
Georg Brandlaed6c662008-01-07 17:25:53 +00003135- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3136
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3138 envvar and sys.dont_write_bytecode attribute. All these can be set
3139 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003140
Georg Brandl3ee81df2008-05-17 18:14:43 +00003141- Improve some exception messages when Windows fails to load an
3142 extension module. Now we get for example '%1 is not a valid Win32
3143 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003144
Georg Brandl3ee81df2008-05-17 18:14:43 +00003145- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003147- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3148 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003149
Christian Heimes0a8143f2007-12-18 23:22:54 +00003150- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003151 and INF. float("nan"), float("inf") and float("-inf") now work on
3152 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003153
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- Compiler now generates simpler and faster code for dictionary
3155 literals. The oparg for BUILD_MAP now indicates an estimated
3156 dictionary size. There is a new opcode, STORE_MAP, for adding
3157 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003158
Georg Brandl3ee81df2008-05-17 18:14:43 +00003159- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003164- Issue #1538: Avoid copying string in split/rsplit if the split char
3165 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003166
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003167- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003168 SystemError.
3169
Nick Coghlanef01d822007-12-03 12:55:17 +00003170- PEP 366: Allow explicit relative imports when executing modules
3171 inside packages with the -m switch via a new module level
3172 __package__ attribute.
3173
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174- Issue #1402: Fix a crash on exit, when another thread is still
3175 running, and if the deallocation of its frames somehow calls the
3176 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003177

3187 file can now be directly executed by passing their name to the
3188 interpreter. The directory/zipfile is automatically inserted as the
3189 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003190
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191- Issue #1265: Fix a problem with sys.settrace, if the tracing
3192 function uses a generator expression when at the same time the
3193 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003194
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003195- sets and frozensets now have an isdisjoint() method.
3196
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003197- optimize the performance of builtin.sum().
3198
Neal Norwitz44f326e2007-10-05 05:29:17 +00003199- Fix warnings found by the new version of the Coverity checker.
3200
Georg Brandl5a7eca12010-03-21 19:29:04 +00003201- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003202 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3203 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003204
Georg Brandl3ee81df2008-05-17 18:14:43 +00003205- Issue #1686386: Tuple's tp_repr did not take into account the
3206 possibility of having a self-referential tuple, which is possible
3207 from C code. Nor did object's tp_str consider that a type's tp_str
3208 could do something that could lead to an inifinite recursion.
3209 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3210 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003211
Georg Brandl3ee81df2008-05-17 18:14:43 +00003212- Issue #1164: It was possible to trigger deadlock when using the
3213 'print' statement to write to a file since the GIL was not released
3214 as needed. Now PyObject_Print() does the right thing along with

Georg Brandl3ee81df2008-05-17 18:14:43 +00003218- Issue #1147: Exceptions were directly allowing string exceptions in
3219 their throw() method even though string exceptions no longer
3220 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003222- Issue #1096: Prevent a segfault from getting the repr of a very
3223 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003224
Brett Cannon1e534b52007-09-07 04:18:30 +00003225- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003226 PyObject_Call() never calling back out to Python code to trigger
3227 recursion depth updates/checks. Required the creation of a static
3228 RuntimeError instance in case normalizing an exception put the
3229 recursion check value past its limit. Fixes crashers
3230 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003231

Neal Norwitz0ac60192007-05-27 04:08:54 +00003245- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003246 __*__ attributes. (Some already existed, e.g., __doc__ and
3247 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003248
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003249- Add -3 option to the interpreter to warn about features that are

3253 calls.
3254
Collin Winter62903052007-05-18 23:11:24 +00003255- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003256 "except E as target:". This is to provide forwards compatibility
3257 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003258
Brett Cannon229cee22007-05-05 01:34:02 +00003259- Deprecate BaseException.message as per PEP 352.
3260
Georg Brandl3ee81df2008-05-17 18:14:43 +00003261- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003262 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003263
Vinay Sajip8549ce32007-05-06 17:53:37 +00003264- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003265 setting a plain string, ie don't expand to single letter identifiers.
3266
Raymond Hettinger13936692007-04-11 18:40:58 +00003267- Request #1191699: Slices can now be pickled.
3268
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003269- Request #1193128: str.translate() now allows a None argument for
3270 translations that only remove characters without re-mapping the
3271 remaining characters.
3272
Georg Brandl5cb76c12007-03-21 09:00:39 +00003273- Patch #1682205: a TypeError while unpacking an iterable is no longer
3274 masked by a generic one with the message "unpack non-sequence".
3275
Neal Norwitzaa754b72007-03-21 06:39:48 +00003276- Remove unused file Python/fmod.c.
3277
Guido van Rossum143b5642007-03-23 04:58:42 +00003278- Bug #1683368: The object.__init__() and object.__new__() methods are
3279 now stricter in rejecting excess arguments. The only time when
3280 either allows excess arguments is when it is not overridden and the
3281 other one is. For backwards compatibility, when both are
3282 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003283 warning later). Also, type.__init__() insists on the same signature
3284 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003285
Georg Brandl3ee81df2008-05-17 18:14:43 +00003286- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3287 object to complex using its __complex__() method before falling back
3288 to the __float__() method. Therefore, the functions in the cmath
3289 module now can operate on objects that define a __complex__()
3290 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003291
Georg Brandl3ee81df2008-05-17 18:14:43 +00003292- Patch #1623563: allow __class__ assignment for classes with
3293 __slots__. The old and the new class are still required to have the
3294 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003295

3301 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003302
Georg Brandl3ee81df2008-05-17 18:14:43 +00003303- Patch #1680015: Don't modify __slots__ tuple if it contains an

3307
Georg Brandl7b9c5552007-03-12 14:30:05 +00003308- Bug #1678647: write a newline after printing an exception in any
3309 case, even when converting the value to a string failed.
3310
Georg Brandl871f1bc2007-03-12 13:17:36 +00003311- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003312 its argument, if it exists. If not, it will work like before. This
3313 allows customizing the output of dir() in the presence of a
3314 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003315
Collin Winter276887b2007-03-12 16:11:39 +00003316- Patch #922167: Python no longer segfaults when faced with infinitely
3317 self-recursive reload() calls (as reported by bug #742342).

3323 parthensized forms. This means complex(repr(x)) now works instead of
3324 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003325
Georg Brandlaa2321b2007-03-07 00:40:28 +00003326- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003327 makes the filenames the warning module prints much more sensible
3328 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003329
Georg Brandl49aafc92007-03-07 00:34:46 +00003330- Variant of patch #697613: don't exit the interpreter on a SystemExit
3331 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003332 variable is given, but break into the interactive interpreter just
3333 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00003340
Georg Brandl0fca97a2007-03-05 22:28:08 +00003341- Patch #1674228: when assigning a slice (old-style), check for the
3342 sq_ass_slice instead of the sq_slice slot.
3343
Georg Brandl3ee81df2008-05-17 18:14:43 +00003344- When printing an unraisable error, don't print exceptions. before
3345 the name. This duplicates the behavior whening normally printing
3346 exceptions.

3355 created a weakref on itself during a __del__ call for new-style
3356 classes (classic classes still have the bug).

3955 Python would crash instead of raising an error.
3956
Thomas Hellerc2f77252007-03-09 19:21:28 +00003957- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
3958 returned string up to the first NUL character.

3969
Georg Brandl3ee81df2008-05-17 18:14:43 +00003970- unittest now verifies more of its assumptions. In particular,
3971 TestCase and TestSuite subclasses (not instances) are no longer
3972 accepted in TestSuite.addTest(). This should cause no
3973 incompatibility since it never made sense with ordinary subclasses
3974 -- the failure just occurred later, with a more cumbersome
3975 exception.

4259 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004260
Georg Brandl3ee81df2008-05-17 18:14:43 +00004261- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004262 that the SMTP.starttls() caller no longer needs to call ehlo()
4263 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004264 does not claim to support starttls. Adds the
4265 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4346 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4347 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004364 time so that opening a database previously created with the DB_DUP
4365 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4366 opens. Specifically: dictionary assignment to a DB object will
4367 replace all values for a given key when the database allows
4368 duplicate values. DB users should use DB.put(k, v) when they want
4369 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004370

4376 characters with ASCII value less than 32. Also, it correctly quotes
4377 dots only if they occur on a single line, as opposed to the previous
4378 behavior of quoting dots if they are the second character of any
4379 line.

4702-----
4703
Georg Brandl3ee81df2008-05-17 18:14:43 +00004704- Unified naming convention for free lists and their limits. All free
4705 lists in Object/ are named ``free_list``, the counter ``numfree``
4706 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4707 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004708
Georg Brandl3ee81df2008-05-17 18:14:43 +00004709- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4710 to ``PyTuple_SetItem``, it can be used to populate a brand new
4711 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004712
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004713- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004715- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4716 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4717 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004718
4719- Patch #1720595: add T_BOOL to the range of structmember types.
4720
4721- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4722 ``PyFloat_GetInfo()`` to the float API.
4723
Georg Brandl3ee81df2008-05-17 18:14:43 +00004724- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4725 of w# format code incorrectly truncated the length to an int, even
4726 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4727 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004728
Georg Brandl3ee81df2008-05-17 18:14:43 +00004729- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4730 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004731
Georg Brandl3ee81df2008-05-17 18:14:43 +00004732- PEP 3123: Provide forward compatibility with Python 3.0, while
4733 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4734 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004735
Georg Brandl3ee81df2008-05-17 18:14:43 +00004736- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4737 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004738
4739- Patch #1733960: Allow T_LONGLONG to accept ints.
4740
4741- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4742
Christian Heimes000a0742008-01-03 22:16:32 +00004743- Added a new API function ``PyImport_ImportModuleNoBlock``.

4746
4747- Fix some leftovers from the conversion from int to Py_ssize_t
4748 (relevant to strings and sequences of more than 2**31 items).
4749
4750- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4751 outside of pystate.c and should not be necessary.
4752
Georg Brandl3ee81df2008-05-17 18:14:43 +00004753- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4754 absolute imports. In earlier versions they might have used relative
4755 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004756
Georg Brandl3ee81df2008-05-17 18:14:43 +00004757- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4758 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004759
Georg Brandl3ee81df2008-05-17 18:14:43 +00004760- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4761 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004767- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4768 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4769 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4770 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004771
Georg Brandl3ee81df2008-05-17 18:14:43 +00004772- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004785- Removed the macfs module. It had been deprecated since Python 2.5.
4786 This lead to the deprecation of macostools.touched() as it relied
4787 solely on macfs and was a no-op under OS X.
