Victor Stinner082a65a2010-07-28 01:55:43 +000045- Issue #6213: Implement getstate() and setstate() methods of utf-8-sig and
46 utf-16 incremental encoders.
47
Ezio Melotti86e5e172010-07-03 05:34:39 +000048- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
49 start byte and the continuation byte(s) are now considered invalid, instead
50 of the number of bytes specified by the start byte.
51 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
52 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
53 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
54 Previous versions returned a single u'\ufffd'.

Mark Dickinsonb671c292010-06-05 12:15:35 +000063 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
64 arises from the "Overriding __eq__ blocks inheritance ..." warning
65 when turned into an exception: in this case the exception simply
66 gets ignored.
Mark Dickinson80068da2010-06-05 11:59:41 +000067
Georg Brandl0ba1f012010-08-01 22:00:39 +000068- Issue #4108: In urllib.robotparser, if there are multiple 'User-agent: *'

83 it from another thread. Patch by Daniel Stutzbach.
84
Mark Dickinsone02c9d22010-05-07 13:23:18 +000085- Issue #1533: fix inconsistency in range function argument
86 processing: any non-float non-integer argument is now converted to
87 an integer (if possible) using its __int__ method. Previously, only
88 small arguments were treated this way; larger arguments (those whose
89 __int__ was outside the range of a C long) would produce a TypeError.
90
Barry Warsaw60537442010-08-03 22:39:42 +000091- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize

1272
Georg Brandl686d53e2009-01-14 00:08:09 +00001273- Issue #4915: Port sysmodule to Windows CE.

1279 Patch by Ziga Seilnacht and Jean-Paul Calderone.

Georg Brandld2094602008-12-05 08:51:30 +00001317 method on file objects with closefd=False. The file descriptor is still
1318 kept open but the file object behaves like a closed file. The ``FileIO``
1319 object also got a new readonly attribute ``closefd``.
1320
Georg Brandlfa71a902008-12-05 09:08:28 +00001321- Issue #3689: The list reversed iterator now supports __length_hint__

1692What's New in Python 2.6.1
1693==========================
1694
1695*Release date: 04-Dec-2008*
1696
1697Core and Builtins
1698-----------------
1699
1700- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1701 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1702 instead of throwing a MemoryError.
1703
1704- Issue #4367: Python would segfault during compiling when the unicodedata
1705 module couldn't be imported and \N escapes were present.
1706
1707- Issue #4348: Some bytearray methods returned that didn't cause any change to
1708 the bytearray, returned the same bytearray instead of a copy.
1709
1710- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1711
1712- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1713
1714- Issue #4048: The parser module now correctly validates relative imports.
1715
1716- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1717 exec statement.
1718
1719- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1720 method does not return iterators for the 4th and 5th items.
1721
1722- Issue #4209: Enabling unicode_literals and the print_function in the same
1723 __future__ import didn't work.
1724
1725- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1726 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1727 really executed because I cannot move to such directory on win2k)
1728
1729- Issue #4069: When set.remove(element) is used with a set element, the element
1730 is temporarily replaced with an equivalent frozenset. But the eventual
1731 KeyError would always report the empty frozenset([]) as the missing key. Now
1732 it correctly refers to the initial element.
1733
1734- Fixed C99 style comments in several files. Python is now C89 compatible
1735 again.

1881
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001882- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1883
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001884- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1885 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1886 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1887 ``printf`` function, whereas PyString_FromFormat has an independent
1888 implementation and uses "%zd" on all platforms for size_t values.
1889 This makes a difference on win64, where ``printf`` needs "%Id" to display
1890 64bit values.
1891
Benjamin Peterson97179b02008-09-09 20:55:01 +00001892- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1893 error.
1894
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001895- Issue #3777: long() applied to a float object now always return a long
1896 object; previously an int would be returned for small values. the __long__
1897 method is allowed to return either an int or a long, but the behaviour of
1898 float objects should not change to respect backward compatibility.
1899
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001900- Issue #3751: str.rpartition would perform a left-partition when called with
1901 a unicode argument.
1902
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001903- Issue #3683: Fix compilation when --without-threads is given.
1904
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001905- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001906 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001907 was correctly parsed but parsing of subsequent arguments failed.
1908
Vinay Sajip35e3b032008-09-01 14:33:59 +00001909- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001910 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1911 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1912 when given a tuple of classes as second argument, were looking up
1913 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1914 type object.
1915
Neal Norwitz18aa3882008-08-24 05:04:52 +00001916- Fix crashes on memory allocation failure found with failmalloc.
1917
1918- Fix memory leaks found with valgrind and update suppressions file.
1919
1920- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1921
1922- Fix problem using wrong name in decimal module reported by pychecker.
1923
Christian Heimes7d4c3172008-08-22 19:47:25 +00001924- Silenced another compiler warning about a used but not defined
1925 function 'stringlib_contains_obj'.
1926
Benjamin Peterson712ee922008-08-24 18:10:20 +00001927- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1928 ``__delslice__``.
1929
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001930- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1931 library targets in the Makefile.
1932
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001933- Issue #1204: The configure script now tests for additional libraries
1934 that may be required when linking against readline. This fixes issues
1935 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00001985 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1986 for catch_warnings() also led to an improvement in the raising of a
1987 DeprecationWarning related to warnings.warn_explicit().
1988
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001989- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002050What's New in Python 2.6 beta 3?
2051================================
2052
Barry Warsaw07a4a382008-08-21 01:15:08 +00002053*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002054
2055Core and Builtins
2056-----------------
2057
Guido van Rossumf8402962008-08-20 15:01:50 +00002058- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2059 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2060 extensions do not automatically benefit from the class attribute
2061 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2062 to their tp_flags field if they care. This is a backwards
2063 compatibility feature; in 3.0, all types will use the cache by
2064 default.
2065
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002066- Keyword arguments can now follow starred arguments. (``f(a, *args,
2067 keyword=23)`` is now valid syntax.)
2068
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002069- ctypes function pointers that are COM methods have a boolean True
2070 value again.
2071
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002072- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2073 by denying s# to parse objects that have a releasebuffer procedure,
2074 and introducing s*.
2075
Georg Brandl1e13ea92008-08-11 09:07:59 +00002076- Issue #3537: Fix an assertion failure when an empty but presized dict
2077 object was stored in the freelist.
2078
Mark Dickinsonb6467572008-08-04 21:30:09 +00002079- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2080 ValueError consistently across platforms.
2081
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002082- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2083 (64bit Unix, for example), unichr() would truncate its argument and return
2084 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2085
Neal Norwitze7d8be82008-07-31 17:17:14 +00002086- Apply security patches from Apple.
2087
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002088- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2089 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2090
Antoine Pitrou92f82162008-07-25 22:22:08 +00002091- Issue #1819: function calls with several named parameters are now on
2092 average 35% faster (as measured by pybench).
2093
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002094- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2095 the python debugger steps into a class statement: the free variables (local
2096 variables defined in an outer scope) would be deleted from the outer scope.
2097
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002098- Issue #2620: Overflow checking when allocating or reallocating memory
2099 was not always being done properly in some python types and extension
2100 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2101 all been updated to perform better checks and places in the code that
2102 would previously leak memory on the error path when such an allocation
2103 failed have been fixed.

2106-------
2107
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002108- Issue #3612: Added some missing basic types in ctypes.wintypes.
2109
Benjamin Petersone977ad42008-08-20 01:42:01 +00002110- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2111 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2112
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002113- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2114 version reported by these tools does not necessarily follow the python
2115 version numbering scheme, so the module is less strict when parsing it.
2116
Nick Coghlanf70385a2008-08-18 12:42:46 +00002117- Issue #2235: Added Py3k warnings for types which will become unhashable
2118 under the stricter __hash__ inheritance rules in 3.0. Several types
2119 which did not meet the rules for hash invariants and were already
2120 unhashable in 3.0 have now been explicitly flagged as unhashable in
2121 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2122 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2123
Brett Cannon88f801d2008-08-18 00:46:22 +00002124- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2125 imported into the module but exposed as part of the module's API.
2126
Brett Cannon7b96f072008-08-18 00:41:11 +00002127- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2128
Brett Cannon46225e72008-08-18 00:36:52 +00002129- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002131- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2132
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002133- Issue #3575: Incremental decoder's decode function now takes bytearray
2134 by using 's*' instead of 't#'.
2135
Jesus Cea585ad8a2009-07-02 15:37:21 +00002136- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002137 fails unicode conversion on 2nd parameter. (windows only)
2138
Georg Brandl21896072010-08-01 22:31:28 +00002139- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00002140 in a redirect.
2141
Brett Cannonabe423e2008-08-16 21:47:07 +00002142- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002143 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002144
Facundo Batistaeb90b782008-08-16 14:44:07 +00002145- Issue #2776: fixed small issue when handling an URL with double slash
2146 after a 302 response in the case of not going through a proxy.
2147
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002148- Issue #2676: in the email package, content-type parsing was hanging on
2149 pathological input because of quadratic or exponential behaviour of a
2150 regular expression.
2151
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002152- Issue #3476: binary buffered reading through the new "io" library is now
2153 thread-safe.
2154
Brett Cannonbf3157b2008-08-14 05:00:03 +00002155- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2156 since mimetools itself is deprecated. Because modules are cached, all
2157 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

Antoine Pitroude781a42008-08-09 12:43:23 +00002193 asking for a specific length. This problem only affected files opened

2237
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002238- Issue #643841: The language reference now provides more detailed

2250-----------------
2251
Georg Brandl3e483f62008-07-16 22:57:41 +00002252- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2253 its methods now allow for items objects that can be converted to
2254 an integer using operator.index().
2255
Mark Dickinson64b7e502008-07-16 09:40:03 +00002256- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2257 produced a ValueError instead of giving the correct float.
2258
Eric Smitha5fa5a22008-07-16 00:11:49 +00002259- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2260 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2261
Mark Dickinson7103aa42008-07-15 19:08:33 +00002262- Issue #3008: the float type has a new instance method 'float.hex'
2263 and a new class method 'float.fromhex' to convert floating-point
2264 numbers to and from hexadecimal strings, respectively.
2265
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002266- Issue #2235: __hash__ is once again inherited by default. To allow
2267 collections.Hashable to remain meaningful in the presence of the
2268 default hash implementation (object.__hash__), it is now possible
2269 to explicit block inheritance of hash by setting __hash__=None at
2270 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2271 level.
2272
Nick Coghlanb028f502008-07-13 14:52:36 +00002273- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2274 the parent module cannot be found while performing an absolute import.
2275 This means that an incorrectly defined __package__ attribute will
2276 now only prevent relative imports in that module rather than causing
2277 all imports from that module to fail.
2278
Nick Coghlan14ff9942008-07-08 14:21:42 +00002279- Issue #2517: Allow unicode messages in Exceptions again by correctly

2289 another thread's dictionary.
2290
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002291- Issue #3004: Minor change to slice.indices(): the start and stop
2292 arguments are now treated identically, making the behaviour easier
2293 to describe and understand. For example, slice(None, -10,
2294 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2295 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2296 10, -1).
2297
Georg Brandl278fc502008-07-19 12:46:12 +00002298- Issue #3219: Calling a function with repeated keyword arguments,
2299 f(a=2, a=23), would not cause a syntax error. This was a regression
2300 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002302- Issue #2862: Make int and float freelist management consistent with
2303 other freelists. Changes their CompactFreeList apis into

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002338- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2339 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002340 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002341 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002357- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Benjamin Peterson23681932008-05-12 21:42:13 +00002727
Vinay Sajip9828b7e2008-06-17 11:04:02 +00002728- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002729 environment to control the '-arch' flags that are used to build
2730 an extension. This was added for compatibility with Apple's build
2731 of Python.
2732
2733- The bundled OSX-specific copy of libbffi is now in sync with the version
2734 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
2735
Georg Brandl25c34082008-08-18 23:09:49 +00002736- The threading module gained aliases for names that will be removed in the

2745
Brett Cannonb61d8012008-05-11 23:39:04 +00002746- ``Lib/lib-old`` is now added to sys.path.
2747
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002748- On MacOS X it is now possible to install the framework in 64-bit
2749 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002750 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002751
2752 This is controlled by the configure argument ``--with-universal-archs``:
2753
2754 - ``--with-universal-archs=all``: install 4-way universal
2755
2756 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2757
2758 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2759
2760 This option should be used in combination with ``--enable-universalsdk=``.
2761
2762 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002812- Issue #1631171: Re-implement the 'warnings' module in C (the
2813 original Python code has been kept as backup). This will allow for
2814 using the 'warning's machinery in such places as the parser where
2815 use of pure Python code is not possible. Both the ``showarning()``
2816 and ``formatwarning()`` gain an optional 'line' argument which is
2817 not called by default for backwards-compatibility reasons. Setting
2818 ``warnings.showwarning()`` to an implementation that lacks support
2819 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002844- The getpass module has been improved on Unix. It now uses /dev/tty
2845 by default and uses stderr instead of stdout. A GetPassWarning is
2846 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002861- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002862 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002882- Issue #2550: The approach used by client/server code for obtaining
2883 ports to listen on in network-oriented tests has been refined in an
2884 effort to facilitate running multiple instances of the entire
2885 regression test suite in parallel without issue.
2886 test_support.bind_port() has been fixed such that it will always
2887 return a unique port -- which wasn't always the case with the
2888 previous implementation, especially if socket options had been set
2889 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2890 new implementation of bind_port() will actually raise an exception
2891 if it is passed an AF_INET/SOCK_STREAM socket with either the
2892 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2893 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2894 the socket it's been passed. This currently only applies to
2895 Windows. This option prevents any other sockets from binding to the
2896 host/port we've bound to, thus removing the possibility of the
2897 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2898 when a second SOCK_STREAM socket binds and accepts to a host/port
2899 that's already been bound by another socket. The optional preferred
2900 port parameter to bind_port() has been removed. Under no
2901 circumstances should tests be hard coding ports!
2902
2903 test_support.find_unused_port() has also been introduced, which will
2904 pass a temporary socket object to bind_port() in order to obtain an
2905 unused port. The temporary socket object is then closed and
2906 deleted, and the port is returned. This method should only be used
2907 for obtaining an unused port in order to pass to an external program
2908 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2909 a parameter to a server-oriented class that doesn't give you direct
2910 access to the underlying socket used.
2911
2912 Finally, test_support.HOST has been introduced, which should be used
2913 for the host argument of any relevant socket calls (i.e. bind and
2914 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002915
2916 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002917 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002918 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2919 test_asynchat and test_socket_ssl.
2920
Georg Brandl3ee81df2008-05-17 18:14:43 +00002921 It is now possible for multiple instances of the regression test
2922 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00003201- Added the future_builtins module, which contains hex() and oct().
3202 These are the PEP 3127 version of these functions, designed to be
3203 compatible with the hex() and oct() builtins from Python 3.0. They
3204 differ slightly in their output formats from the existing, unchanged
3205 Python 2.6 builtins. The expected usage of the future_builtins
3206 module is:
3207 from future_builtins import hex, oct
3208
Eric Smith7ef40bf2008-02-20 23:34:22 +00003209- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3210 exponents for exponents with absolute value < 100. Follows C99
3211 standard. This is a change on Windows, which would use 3 digits.
3212 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3213 so that any alterations it does to the resulting string will be
3214 available in stringlib/formatter.h (for float.__format__).
3215
Eric Smith5a3c1352008-02-19 13:21:56 +00003216- Implemented PEP 3101, Advanced String Formatting. This adds a new
3217 builtin format(); a format() method for str and unicode; a
3218 __format__() method to object, str, unicode, int, long, float, and
3219 datetime; the class string.Formatter; and the C API
3220 PyObject_Format().
3221
Georg Brandl3ee81df2008-05-17 18:14:43 +00003222- Fixed several potential crashes, all caused by specially crafted
3223 __del__ methods exploiting objects in temporarily inconsistent
3224 state.

3228 a slot on a registered virtual subclass.

3234 in order to allow pymalloc to free more arenas. Python may give back
3235 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003236
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237- Issue #2045: Fix an infinite recursion triggered when printing a
3238 subclass of collections.defaultdict, if its default_factory is set
3239 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003240
Christian Heimesf75dbef2008-02-08 00:11:31 +00003241- Fixed a minor memory leak in dictobject.c. The content of the free
3242 list was not freed on interpreter shutdown.

Georg Brandl5a7eca12010-03-21 19:29:04 +00003244- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003246
Georg Brandl3ee81df2008-05-17 18:14:43 +00003247- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3248 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003249 to compact the internal free lists of pre-allocted ints and floats.
3250
Georg Brandl3ee81df2008-05-17 18:14:43 +00003251- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3252 calls. Python expected the return type int but the fork familie
3253 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003254
Georg Brandl3ee81df2008-05-17 18:14:43 +00003255- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3256 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003257
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3259 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003260
Georg Brandl3ee81df2008-05-17 18:14:43 +00003261- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3262 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003263
Georg Brandl3ee81df2008-05-17 18:14:43 +00003264- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3265 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003266
Georg Brandl3ee81df2008-05-17 18:14:43 +00003267- Patch #1473257: generator objects gain a gi_code attribute. This is
3268 the same object as the func_code attribute of the function that
3269 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003270
Georg Brandl3ee81df2008-05-17 18:14:43 +00003271- Issue #1920: "while 0" statements were completely removed by the
3272 compiler, even in the presence of an "else" clause, which is
3273 supposed to be run when the condition is false. Now the compiler
3274 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003275
Guido van Rossumeead05f2008-01-24 18:21:02 +00003276- A few crashers fixed: weakref_in_del.py (issue #1377858);
3277 loosing_dict_ref.py (issue #1303614, test67.py);
3278 borrowed_ref_[34].py (not in tracker).
3279
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003280- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003281 suppressed while an extension is loaded by calling SetErrorMode in
3282 dynload_win.c. The error is still reported properly.
3283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003285 several extension methods and modules do not work without unicode
3286 support.
3287
Georg Brandl26543b12008-01-21 18:36:51 +00003288- Issue #1882: when compiling code from a string, encoding cookies in the
3289 second line of code were not always recognized correctly.
3290
Georg Brandl14404b62008-01-19 19:27:05 +00003291- Issue #1679: "0x" was taken as a valid integer literal.
3292
Georg Brandl6caad7d2008-01-26 14:19:22 +00003293- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003294 added.
3295
Christian Heimesc94e2b52008-01-14 04:13:37 +00003296- sys.float_info / PyFloat_GetInfo: The floating point information
3297 object was converted from a dict to a specialized structseq object.
3298
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299- Patch #1816: Added sys.flags structseq. It exposes the status of
3300 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003301
Georg Brandl3ee81df2008-05-17 18:14:43 +00003302- Objects/structseq.c: Implemented new structseq representation. The
3303 patch makes structseqs (e.g. the return value of os.stat) more
3304 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003305
Georg Brandl3ee81df2008-05-17 18:14:43 +00003306- Patch #1700288: added a type attribute cache that caches method
3307 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003308
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003309- Bug #1776: __import__() no longer accepts filenames on any platform.
3310 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003311
Georg Brandlaed6c662008-01-07 17:25:53 +00003312- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3313
Georg Brandl3ee81df2008-05-17 18:14:43 +00003314- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3315 envvar and sys.dont_write_bytecode attribute. All these can be set
3316 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003317
Georg Brandl3ee81df2008-05-17 18:14:43 +00003318- Improve some exception messages when Windows fails to load an
3319 extension module. Now we get for example '%1 is not a valid Win32
3320 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003321
Georg Brandl3ee81df2008-05-17 18:14:43 +00003322- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3325 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003326
Christian Heimes0a8143f2007-12-18 23:22:54 +00003327- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003328 and INF. float("nan"), float("inf") and float("-inf") now work on
3329 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003330
Georg Brandl3ee81df2008-05-17 18:14:43 +00003331- Compiler now generates simpler and faster code for dictionary
3332 literals. The oparg for BUILD_MAP now indicates an estimated
3333 dictionary size. There is a new opcode, STORE_MAP, for adding
3334 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003335
Georg Brandl3ee81df2008-05-17 18:14:43 +00003336- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003341- Issue #1538: Avoid copying string in split/rsplit if the split char
3342 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003343
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003344- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003345 SystemError.
3346
Nick Coghlanef01d822007-12-03 12:55:17 +00003347- PEP 366: Allow explicit relative imports when executing modules
3348 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00003363- Patch #1739468: Directories and zipfiles containing a __main__.py
3364 file can now be directly executed by passing their name to the
3365 interpreter. The directory/zipfile is automatically inserted as the
3366 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003367
Georg Brandl3ee81df2008-05-17 18:14:43 +00003368- Issue #1265: Fix a problem with sys.settrace, if the tracing
3369 function uses a generator expression when at the same time the
3370 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003371
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003372- sets and frozensets now have an isdisjoint() method.
3373
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003374- optimize the performance of builtin.sum().
3375
Neal Norwitz44f326e2007-10-05 05:29:17 +00003376- Fix warnings found by the new version of the Coverity checker.
3377
Georg Brandl5a7eca12010-03-21 19:29:04 +00003378- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003379 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3380 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003381
Georg Brandl3ee81df2008-05-17 18:14:43 +00003382- Issue #1686386: Tuple's tp_repr did not take into account the
3383 possibility of having a self-referential tuple, which is possible
3384 from C code. Nor did object's tp_str consider that a type's tp_str
3385 could do something that could lead to an inifinite recursion.
3386 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3387 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003388
Georg Brandl3ee81df2008-05-17 18:14:43 +00003389- Issue #1164: It was possible to trigger deadlock when using the
3390 'print' statement to write to a file since the GIL was not released
3391 as needed. Now PyObject_Print() does the right thing along with
3392 various tp_print implementations of the built-in types and those in
3393 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003394
Georg Brandl3ee81df2008-05-17 18:14:43 +00003395- Issue #1147: Exceptions were directly allowing string exceptions in
3396 their throw() method even though string exceptions no longer
3397 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003398
Georg Brandl3ee81df2008-05-17 18:14:43 +00003399- Issue #1096: Prevent a segfault from getting the repr of a very
3400 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003401
Brett Cannon1e534b52007-09-07 04:18:30 +00003402- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003403 PyObject_Call() never calling back out to Python code to trigger
3404 recursion depth updates/checks. Required the creation of a static
3405 RuntimeError instance in case normalizing an exception put the
3406 recursion check value past its limit. Fixes crashers
3407 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003408
Georg Brandl3ee81df2008-05-17 18:14:43 +00003409- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003422- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003423 __*__ attributes. (Some already existed, e.g., __doc__ and
3424 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003425
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003426- Add -3 option to the interpreter to warn about features that are
3427 deprecated and will be changed/removed in Python 3.0.
3428
Georg Brandl2134e752007-05-21 20:34:16 +00003429- Patch #1686487: you can now pass any mapping after '**' in function
3430 calls.
3431
Collin Winter62903052007-05-18 23:11:24 +00003432- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433 "except E as target:". This is to provide forwards compatibility
3434 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003435
Brett Cannon229cee22007-05-05 01:34:02 +00003436- Deprecate BaseException.message as per PEP 352.
3437
Georg Brandl3ee81df2008-05-17 18:14:43 +00003438- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003439 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003440
Vinay Sajip8549ce32007-05-06 17:53:37 +00003441- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003442 setting a plain string, ie don't expand to single letter identifiers.
3443
Raymond Hettinger13936692007-04-11 18:40:58 +00003444- Request #1191699: Slices can now be pickled.
3445
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003446- Request #1193128: str.translate() now allows a None argument for
3447 translations that only remove characters without re-mapping the
3448 remaining characters.
3449
Georg Brandl5cb76c12007-03-21 09:00:39 +00003450- Patch #1682205: a TypeError while unpacking an iterable is no longer
3451 masked by a generic one with the message "unpack non-sequence".
3452
Neal Norwitzaa754b72007-03-21 06:39:48 +00003453- Remove unused file Python/fmod.c.
3454
Guido van Rossum143b5642007-03-23 04:58:42 +00003455- Bug #1683368: The object.__init__() and object.__new__() methods are
3456 now stricter in rejecting excess arguments. The only time when
3457 either allows excess arguments is when it is not overridden and the
3458 other one is. For backwards compatibility, when both are
3459 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003460 warning later). Also, type.__init__() insists on the same signature
3461 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003462
Georg Brandl3ee81df2008-05-17 18:14:43 +00003463- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3464 object to complex using its __complex__() method before falling back
3465 to the __float__() method. Therefore, the functions in the cmath
3466 module now can operate on objects that define a __complex__()
3467 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003468
Georg Brandl3ee81df2008-05-17 18:14:43 +00003469- Patch #1623563: allow __class__ assignment for classes with
3470 __slots__. The old and the new class are still required to have the
3471 same slot names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004541 time so that opening a database previously created with the DB_DUP
4542 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4543 opens. Specifically: dictionary assignment to a DB object will
4544 replace all values for a given key when the database allows
4545 duplicate values. DB users should use DB.put(k, v) when they want
4546 to store duplicates; not DB[k] = v.

4555 behavior of quoting dots if they are the second character of any
4556 line.
