13-----------------
14
Ezio Melotti86e5e172010-07-03 05:34:39 +000015- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
16 start byte and the continuation byte(s) are now considered invalid, instead
17 of the number of bytes specified by the start byte.
18 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
19 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
20 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
21 Previous versions returned a single u'\ufffd'.
22
Benjamin Peterson8d649632010-06-22 19:21:33 +000023- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
24
Antoine Pitrou4595e512010-06-11 21:48:02 +000025- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
26 the interpreter with characters outside the Basic Multilingual Plane
27 (higher than 0x10000).
28
Mark Dickinson80068da2010-06-05 11:59:41 +000029- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsonb671c292010-06-05 12:15:35 +000030 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
31 arises from the "Overriding __eq__ blocks inheritance ..." warning
32 when turned into an exception: in this case the exception simply
33 gets ignored.
Mark Dickinson80068da2010-06-05 11:59:41 +000034
Benjamin Peterson85633362010-06-08 14:58:25 +000035- In the unicode/str.format(), raise a ValueError when indexes to arguments are
36 too large.

46
Mark Dickinsone02c9d22010-05-07 13:23:18 +000047- Issue #1533: fix inconsistency in range function argument
48 processing: any non-float non-integer argument is now converted to
49 an integer (if possible) using its __int__ method. Previously, only
50 small arguments were treated this way; larger arguments (those whose
51 __int__ was outside the range of a C long) would produce a TypeError.
52
Benjamin Petersonc218ce82010-04-16 22:43:53 +000053- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
54 passed to bytearray.
55
Benjamin Peterson8a488082010-04-06 21:55:35 +000056- Issue #8329: Don't return the same lists from select.select when no fds are

67
Victor Stinner0217c952010-03-21 13:09:24 +000068- Issue #7820: The parser tokenizer restores all bytes in the right if
69 the BOM check fails.

72
Antoine Pitrou52ca5162010-05-21 17:22:43 +000073C-API
74-----
75
76- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
77 embedders of the interpreter to set sys.argv without also modifying
78 sys.path. This helps fix `CVE-2008-5983
79 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

Ronald Oussorenac08e302010-07-24 10:05:19 +0000315- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
316 compared to other unix systems. In particular, os.getgroups() does
317 not reflect any changes made using os.setgroups() but basicly always

1580What's New in Python 2.6.1
1581==========================
1582
1583*Release date: 04-Dec-2008*
1584
1585Core and Builtins
1586-----------------
1587
1588- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1589 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1590 instead of throwing a MemoryError.
1591
1592- Issue #4367: Python would segfault during compiling when the unicodedata
1593 module couldn't be imported and \N escapes were present.
1594
1595- Issue #4348: Some bytearray methods returned that didn't cause any change to
1596 the bytearray, returned the same bytearray instead of a copy.
1597
1598- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1599
1600- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1601
1602- Issue #4048: The parser module now correctly validates relative imports.
1603
1604- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1605 exec statement.
1606
1607- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1608 method does not return iterators for the 4th and 5th items.
1609
1610- Issue #4209: Enabling unicode_literals and the print_function in the same
1611 __future__ import didn't work.
1612
1613- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1614 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1615 really executed because I cannot move to such directory on win2k)
1616
1617- Issue #4069: When set.remove(element) is used with a set element, the element
1618 is temporarily replaced with an equivalent frozenset. But the eventual
1619 KeyError would always report the empty frozenset([]) as the missing key. Now
1620 it correctly refers to the initial element.
1621
1622- Fixed C99 style comments in several files. Python is now C89 compatible
1623 again.

1771
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001772- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1773 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1774 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1775 ``printf`` function, whereas PyString_FromFormat has an independent
1776 implementation and uses "%zd" on all platforms for size_t values.
1777 This makes a difference on win64, where ``printf`` needs "%Id" to display
1778 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001780- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Vinay Sajip35e3b032008-09-01 14:33:59 +00001797- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001798 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1799 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1800 when given a tuple of classes as second argument, were looking up
1801 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1802 type object.

1874 for catch_warnings() also led to an improvement in the raising of a
1875 DeprecationWarning related to warnings.warn_explicit().
1876
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001877- The deprecation warnings for the old camelCase threading API were removed.
1878

1880
Christian Heimesa27a62e2008-08-22 19:55:54 +00001881- Silenced a trivial compiler warning in the sqlite module.
1882
Christian Heimes1cc69632008-08-22 20:10:27 +00001883- Fixed two format strings in the _collections module.
1884
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001885- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a
1886 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00001887
Gregory P. Smithd7122032008-09-02 05:36:11 +00001888- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
1889 non-integer floating point number.
1890
Vinay Sajip65d66e12008-09-04 07:31:21 +00001891- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

1895-----------------
1896
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001897- Issue #2975: When compiling several extension modules with Visual Studio 2008
1898 from the same python interpreter, some environment variables would grow
1899 without limit.
1900
Benjamin Peterson37346b22008-08-23 20:27:43 +00001901- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1902 exploitation of poor argument checking.
1903
Gerhard Häringef2276b2008-09-12 13:54:06 +00001904- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
1905
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00001906- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
1907 remaining ones have "pysqlite_" prefix.
1908
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001909- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00001916- Issue #3781: Add test.test_support.check_warnings() as a convenience
1917 wrapper for warnings.catch_warnings() that makes it easier to check
1918 that expected warning messages are being reported.
1919
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001920- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001938What's New in Python 2.6 beta 3?
1939================================
1940
Barry Warsaw07a4a382008-08-21 01:15:08 +00001941*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001942
1943Core and Builtins
1944-----------------
1945
Guido van Rossumf8402962008-08-20 15:01:50 +00001946- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1947 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1948 extensions do not automatically benefit from the class attribute
1949 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1950 to their tp_flags field if they care. This is a backwards
1951 compatibility feature; in 3.0, all types will use the cache by
1952 default.
1953
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001954- Keyword arguments can now follow starred arguments. (``f(a, *args,
1955 keyword=23)`` is now valid syntax.)
1956
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001957- ctypes function pointers that are COM methods have a boolean True
1958 value again.
1959
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001960- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1961 by denying s# to parse objects that have a releasebuffer procedure,
1962 and introducing s*.
1963
Georg Brandl1e13ea92008-08-11 09:07:59 +00001964- Issue #3537: Fix an assertion failure when an empty but presized dict
1965 object was stored in the freelist.
1966
Mark Dickinsonb6467572008-08-04 21:30:09 +00001967- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1968 ValueError consistently across platforms.
1969
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001970- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1971 (64bit Unix, for example), unichr() would truncate its argument and return
1972 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1973
Neal Norwitze7d8be82008-07-31 17:17:14 +00001974- Apply security patches from Apple.
1975
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001976- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1977 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1978
Antoine Pitrou92f82162008-07-25 22:22:08 +00001979- Issue #1819: function calls with several named parameters are now on
1980 average 35% faster (as measured by pybench).
1981
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001982- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1983 the python debugger steps into a class statement: the free variables (local
1984 variables defined in an outer scope) would be deleted from the outer scope.
1985
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001986- Issue #2620: Overflow checking when allocating or reallocating memory
1987 was not always being done properly in some python types and extension
1988 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1989 all been updated to perform better checks and places in the code that
1990 would previously leak memory on the error path when such an allocation
1991 failed have been fixed.
1992
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001993Library

1997
Benjamin Petersone977ad42008-08-20 01:42:01 +00001998- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1999 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2000
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002001- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2002 version reported by these tools does not necessarily follow the python
2003 version numbering scheme, so the module is less strict when parsing it.
2004
Nick Coghlanf70385a2008-08-18 12:42:46 +00002005- Issue #2235: Added Py3k warnings for types which will become unhashable
2006 under the stricter __hash__ inheritance rules in 3.0. Several types
2007 which did not meet the rules for hash invariants and were already
2008 unhashable in 3.0 have now been explicitly flagged as unhashable in
2009 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2010 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2011
Brett Cannon88f801d2008-08-18 00:46:22 +00002012- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2013 imported into the module but exposed as part of the module's API.
2014
Brett Cannon7b96f072008-08-18 00:41:11 +00002015- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2016
Brett Cannon46225e72008-08-18 00:36:52 +00002017- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2020
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002021- Issue #3575: Incremental decoder's decode function now takes bytearray
2022 by using 's*' instead of 't#'.
2023
Jesus Cea585ad8a2009-07-02 15:37:21 +00002024- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002025 fails unicode conversion on 2nd parameter. (windows only)
2026
Facundo Batista94f243a2008-08-17 03:38:39 +00002027- Issue 2464. urllib2 now supports a malformation in the URL received
2028 in a redirect.
2029
Brett Cannonabe423e2008-08-16 21:47:07 +00002030- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002031 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002032
Facundo Batistaeb90b782008-08-16 14:44:07 +00002033- Issue #2776: fixed small issue when handling an URL with double slash
2034 after a 302 response in the case of not going through a proxy.
2035
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002036- Issue #2676: in the email package, content-type parsing was hanging on
2037 pathological input because of quadratic or exponential behaviour of a
2038 regular expression.
2039
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002040- Issue #3476: binary buffered reading through the new "io" library is now
2041 thread-safe.
2042
Brett Cannonbf3157b2008-08-14 05:00:03 +00002043- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2044 since mimetools itself is deprecated. Because modules are cached, all
2045 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2046
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002047- Issue #3134: shutil referenced undefined WindowsError symbol.
2048
Robert Schuppenies14646332008-08-10 11:01:53 +00002049- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2050 menu entries were not deleted.
2051
Brett Cannon83e81842008-08-09 23:30:55 +00002052- Copied the implementation of reduce() to _functools.reduce() to have a
2053 version that did not raise a DeprecationWarning under -3.
2054
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002055- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2056 a MemoryError rather than silently stop the iteration.
2057
Guido van Rossum59ce9012008-08-09 14:55:34 +00002058- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2059 to _sre.compile() will now be rejected. This should not affect anybody
2060 since the re.compile() function never generates invalid re-bytecode.
2061
Skip Montanaroa032bf42008-08-08 22:52:51 +00002062- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2063 upon first access it can be automatically initialized from the csv file if
2064 it wasn't initialized during instantiation.
2065
Brett Cannon3aa2a492008-08-06 22:28:09 +00002066- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2067 the reload() built-in has been removed.
2068
Brett Cannon7e30b672008-08-04 21:52:25 +00002069- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002070 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2078 raised an AttributeError.
2079
Benjamin Peterson01a24322008-07-28 23:35:27 +00002080- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002081 asking for a specific length. This problem only affected files opened
2082 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002083
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002084- Issue #3449: Update decimal module to use most recent specification

2106
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002107- Issue #3394: zipfile.writestr sets external attributes when passed a
2108 file name rather than a ZipInfo instance, so files are extracted with
2109 mode 0600 rather than 000 under Unix.
2110
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002111- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2112 argument in python 2.5, this broke code that subclassed Popen to include its

2127 coverage of the lookup process for special methods. The disclaimers
2128 regarding lack of coverage of new-style classes have also been
2129 removed, since the coverage is now fairly reasonable.

2134
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002135*Release date: 17-Jul-2008*

2138-----------------
2139
Georg Brandl3e483f62008-07-16 22:57:41 +00002140- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2141 its methods now allow for items objects that can be converted to
2142 an integer using operator.index().
2143
Mark Dickinson64b7e502008-07-16 09:40:03 +00002144- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2145 produced a ValueError instead of giving the correct float.
2146
Eric Smitha5fa5a22008-07-16 00:11:49 +00002147- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2148 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2149
Mark Dickinson7103aa42008-07-15 19:08:33 +00002150- Issue #3008: the float type has a new instance method 'float.hex'
2151 and a new class method 'float.fromhex' to convert floating-point
2152 numbers to and from hexadecimal strings, respectively.
2153
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002154- Issue #2235: __hash__ is once again inherited by default. To allow
2155 collections.Hashable to remain meaningful in the presence of the
2156 default hash implementation (object.__hash__), it is now possible
2157 to explicit block inheritance of hash by setting __hash__=None at
2158 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2159 level.
2160
Nick Coghlanb028f502008-07-13 14:52:36 +00002161- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2162 the parent module cannot be found while performing an absolute import.
2163 This means that an incorrectly defined __package__ attribute will
2164 now only prevent relative imports in that module rather than causing
2165 all imports from that module to fail.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002638 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002639

Georg Brandl3ee81df2008-05-17 18:14:43 +00002700- Issue #1631171: Re-implement the 'warnings' module in C (the
2701 original Python code has been kept as backup). This will allow for
2702 using the 'warning's machinery in such places as the parser where
2703 use of pure Python code is not possible. Both the ``showarning()``
2704 and ``formatwarning()`` gain an optional 'line' argument which is
2705 not called by default for backwards-compatibility reasons. Setting
2706 ``warnings.showwarning()`` to an implementation that lacks support
2707 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002770- Issue #2550: The approach used by client/server code for obtaining
2771 ports to listen on in network-oriented tests has been refined in an
2772 effort to facilitate running multiple instances of the entire
2773 regression test suite in parallel without issue.
2774 test_support.bind_port() has been fixed such that it will always
2775 return a unique port -- which wasn't always the case with the
2776 previous implementation, especially if socket options had been set
2777 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2778 new implementation of bind_port() will actually raise an exception
2779 if it is passed an AF_INET/SOCK_STREAM socket with either the
2780 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2781 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2782 the socket it's been passed. This currently only applies to
2783 Windows. This option prevents any other sockets from binding to the
2784 host/port we've bound to, thus removing the possibility of the
2785 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2786 when a second SOCK_STREAM socket binds and accepts to a host/port
2787 that's already been bound by another socket. The optional preferred
2788 port parameter to bind_port() has been removed. Under no
2789 circumstances should tests be hard coding ports!
2790
2791 test_support.find_unused_port() has also been introduced, which will
2792 pass a temporary socket object to bind_port() in order to obtain an
2793 unused port. The temporary socket object is then closed and
2794 deleted, and the port is returned. This method should only be used
2795 for obtaining an unused port in order to pass to an external program
2796 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2797 a parameter to a server-oriented class that doesn't give you direct
2798 access to the underlying socket used.
2799
2800 Finally, test_support.HOST has been introduced, which should be used
2801 for the host argument of any relevant socket calls (i.e. bind and
2802 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002803
2804 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002805 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002806 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2807 test_asynchat and test_socket_ssl.
2808
Georg Brandl3ee81df2008-05-17 18:14:43 +00002809 It is now possible for multiple instances of the regression test
2810 suite to run in parallel without issue.

3078
Fred Drakea8ee94b2008-03-01 02:45:07 +00003079- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003080 644. The mode is now inherited from the py file.

3083
3084- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003085
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003086- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003087 issue 215555 for a discussion.
3088
Eric Smitha73fbe72008-02-23 03:09:44 +00003089- Added the future_builtins module, which contains hex() and oct().
3090 These are the PEP 3127 version of these functions, designed to be
3091 compatible with the hex() and oct() builtins from Python 3.0. They
3092 differ slightly in their output formats from the existing, unchanged
3093 Python 2.6 builtins. The expected usage of the future_builtins
3094 module is:
3095 from future_builtins import hex, oct
3096
Eric Smith7ef40bf2008-02-20 23:34:22 +00003097- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3098 exponents for exponents with absolute value < 100. Follows C99
3099 standard. This is a change on Windows, which would use 3 digits.
3100 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3101 so that any alterations it does to the resulting string will be
3102 available in stringlib/formatter.h (for float.__format__).
3103
Eric Smith5a3c1352008-02-19 13:21:56 +00003104- Implemented PEP 3101, Advanced String Formatting. This adds a new
3105 builtin format(); a format() method for str and unicode; a
3106 __format__() method to object, str, unicode, int, long, float, and
3107 datetime; the class string.Formatter; and the C API
3108 PyObject_Format().
3109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Fixed several potential crashes, all caused by specially crafted
3111 __del__ methods exploiting objects in temporarily inconsistent
3112 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003113
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003114- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003115 prevent a possible crash: an Abstract Base Class would try to access
3116 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003117

Georg Brandl3ee81df2008-05-17 18:14:43 +00003121- Clear all free lists during a gc.collect() of the highest generation
3122 in order to allow pymalloc to free more arenas. Python may give back
3123 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003124
Georg Brandl3ee81df2008-05-17 18:14:43 +00003125- Issue #2045: Fix an infinite recursion triggered when printing a
3126 subclass of collections.defaultdict, if its default_factory is set
3127 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003128
Christian Heimesf75dbef2008-02-08 00:11:31 +00003129- Fixed a minor memory leak in dictobject.c. The content of the free
3130 list was not freed on interpreter shutdown.
3131
Georg Brandl5a7eca12010-03-21 19:29:04 +00003132- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003133 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003134
Georg Brandl3ee81df2008-05-17 18:14:43 +00003135- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3136 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003137 to compact the internal free lists of pre-allocted ints and floats.
3138
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3140 calls. Python expected the return type int but the fork familie
3141 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003142
Georg Brandl3ee81df2008-05-17 18:14:43 +00003143- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3144 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003152- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3153 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003154
Georg Brandl3ee81df2008-05-17 18:14:43 +00003155- Patch #1473257: generator objects gain a gi_code attribute. This is
3156 the same object as the func_code attribute of the function that
3157 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003158
Georg Brandl3ee81df2008-05-17 18:14:43 +00003159- Issue #1920: "while 0" statements were completely removed by the
3160 compiler, even in the presence of an "else" clause, which is
3161 supposed to be run when the condition is false. Now the compiler
3162 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003163
Guido van Rossumeead05f2008-01-24 18:21:02 +00003164- A few crashers fixed: weakref_in_del.py (issue #1377858);
3165 loosing_dict_ref.py (issue #1303614, test67.py);
3166 borrowed_ref_[34].py (not in tracker).
3167
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003168- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003169 suppressed while an extension is loaded by calling SetErrorMode in
3170 dynload_win.c. The error is still reported properly.
3171
Georg Brandl3ee81df2008-05-17 18:14:43 +00003172- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003173 several extension methods and modules do not work without unicode
3174 support.
3175
Georg Brandl26543b12008-01-21 18:36:51 +00003176- Issue #1882: when compiling code from a string, encoding cookies in the
3177 second line of code were not always recognized correctly.
3178
Georg Brandl14404b62008-01-19 19:27:05 +00003179- Issue #1679: "0x" was taken as a valid integer literal.
3180
Georg Brandl6caad7d2008-01-26 14:19:22 +00003181- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003182 added.
3183
Christian Heimesc94e2b52008-01-14 04:13:37 +00003184- sys.float_info / PyFloat_GetInfo: The floating point information
3185 object was converted from a dict to a specialized structseq object.
3186
Georg Brandl3ee81df2008-05-17 18:14:43 +00003187- Patch #1816: Added sys.flags structseq. It exposes the status of
3188 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003189
Georg Brandl3ee81df2008-05-17 18:14:43 +00003190- Objects/structseq.c: Implemented new structseq representation. The
3191 patch makes structseqs (e.g. the return value of os.stat) more
3192 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003193
Georg Brandl3ee81df2008-05-17 18:14:43 +00003194- Patch #1700288: added a type attribute cache that caches method

3203 envvar and sys.dont_write_bytecode attribute. All these can be set
3204 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003205
Georg Brandl3ee81df2008-05-17 18:14:43 +00003206- Improve some exception messages when Windows fails to load an
3207 extension module. Now we get for example '%1 is not a valid Win32
3208 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003215- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003216 and INF. float("nan"), float("inf") and float("-inf") now work on
3217 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003218
Georg Brandl3ee81df2008-05-17 18:14:43 +00003219- Compiler now generates simpler and faster code for dictionary
3220 literals. The oparg for BUILD_MAP now indicates an estimated
3221 dictionary size. There is a new opcode, STORE_MAP, for adding
3222 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003223
Georg Brandl3ee81df2008-05-17 18:14:43 +00003224- Issue #1638: %zd configure test fails on Linux.

3265
Georg Brandl5a7eca12010-03-21 19:29:04 +00003266- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003267 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3268 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003269
Georg Brandl3ee81df2008-05-17 18:14:43 +00003270- Issue #1686386: Tuple's tp_repr did not take into account the
3271 possibility of having a self-referential tuple, which is possible
3272 from C code. Nor did object's tp_str consider that a type's tp_str
3273 could do something that could lead to an inifinite recursion.
3274 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3275 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003276
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277- Issue #1164: It was possible to trigger deadlock when using the
3278 'print' statement to write to a file since the GIL was not released
3279 as needed. Now PyObject_Print() does the right thing along with
3280 various tp_print implementations of the built-in types and those in
3281 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003291 PyObject_Call() never calling back out to Python code to trigger
3292 recursion depth updates/checks. Required the creation of a static
3293 RuntimeError instance in case normalizing an exception put the
3294 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00003310- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003311 __*__ attributes. (Some already existed, e.g., __doc__ and
3312 __name__.)

3318 calls.
3319
Collin Winter62903052007-05-18 23:11:24 +00003320- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003321 "except E as target:". This is to provide forwards compatibility
3322 with Python 3.0.

3342
Guido van Rossum143b5642007-03-23 04:58:42 +00003343- Bug #1683368: The object.__init__() and object.__new__() methods are
3344 now stricter in rejecting excess arguments. The only time when
3345 either allows excess arguments is when it is not overridden and the
3346 other one is. For backwards compatibility, when both are
3347 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003348 warning later). Also, type.__init__() insists on the same signature
3349 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003350
Georg Brandl3ee81df2008-05-17 18:14:43 +00003351- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3352 object to complex using its __complex__() method before falling back
3353 to the __float__() method. Therefore, the functions in the cmath
3354 module now can operate on objects that define a __complex__()
3355 method.

3372
Georg Brandl7b9c5552007-03-12 14:30:05 +00003373- Bug #1678647: write a newline after printing an exception in any
3374 case, even when converting the value to a string failed.
3375
Georg Brandl871f1bc2007-03-12 13:17:36 +00003376- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003377 its argument, if it exists. If not, it will work like before. This
3378 allows customizing the output of dir() in the presence of a
3379 __getattr__().

3389 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003390
Georg Brandlaa2321b2007-03-07 00:40:28 +00003391- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392 makes the filenames the warning module prints much more sensible
3393 when a PYTHONSTARTUP file is used.

3408
Georg Brandl3ee81df2008-05-17 18:14:43 +00003409- When printing an unraisable error, don't print exceptions. before

Georg Brandl92a6bae2007-03-13 17:43:32 +00003978- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003979 are set for invalid interpolation sequences that would lead to

4036 TestCase and TestSuite subclasses (not instances) are no longer
4037 accepted in TestSuite.addTest(). This should cause no

4039 -- the failure just occurred later, with a more cumbersome
4040 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004321- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4322 with RFC 3207 and forgets any knowledge obtained from the server not
4323 obtained from the TLS negotiation itself. Patch contributed by Bill
4324 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004325
Georg Brandl3ee81df2008-05-17 18:14:43 +00004326- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004327 that the SMTP.starttls() caller no longer needs to call ehlo()
4328 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004329 does not claim to support starttls. Adds the
4330 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00004414

Georg Brandl3ee81df2008-05-17 18:14:43 +00004429 time so that opening a database previously created with the DB_DUP
4430 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4431 opens. Specifically: dictionary assignment to a DB object will
4432 replace all values for a given key when the database allows
4433 duplicate values. DB users should use DB.put(k, v) when they want
4434 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004435

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004713- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004714 periodic threadstate and signal checking in tight loops. By
4715 default, this option is turned-off. It should only be enabled in
4716 debugged, performance critical applications.

4768
Georg Brandl3ee81df2008-05-17 18:14:43 +00004769- Unified naming convention for free lists and their limits. All free
4770 lists in Object/ are named ``free_list``, the counter ``numfree``
4771 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4772 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004773
Georg Brandl3ee81df2008-05-17 18:14:43 +00004774- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4775 to ``PyTuple_SetItem``, it can be used to populate a brand new
4776 frozenset; but it does not steal a reference to the added item.

4788
Georg Brandl3ee81df2008-05-17 18:14:43 +00004789- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4790 of w# format code incorrectly truncated the length to an int, even
4791 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4792 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004793
Georg Brandl3ee81df2008-05-17 18:14:43 +00004794- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4814
4815- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4816 outside of pystate.c and should not be necessary.
4817
Georg Brandl3ee81df2008-05-17 18:14:43 +00004818- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4819 absolute imports. In earlier versions they might have used relative
4820 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004821
Georg Brandl3ee81df2008-05-17 18:14:43 +00004822- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4823 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004824
Georg Brandl3ee81df2008-05-17 18:14:43 +00004825- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004850- Removed the macfs module. It had been deprecated since Python 2.5.
4851 This lead to the deprecation of macostools.touched() as it relied
