574What's New in Python 2.6.1
575==========================
576
577*Release date: 04-Dec-2008*
578
579Core and Builtins
580-----------------
581
582- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
583 interpreter to abort ("Fatal Python error: Could not reset the stack!")
584 instead of throwing a MemoryError.
585
586- Issue #4367: Python would segfault during compiling when the unicodedata
587 module couldn't be imported and \N escapes were present.
588
589- Issue #4348: Some bytearray methods returned that didn't cause any change to
590 the bytearray, returned the same bytearray instead of a copy.
591
592- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
593
594- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
595
596- Issue #4048: The parser module now correctly validates relative imports.
597
598- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
599 exec statement.
600
601- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
602 method does not return iterators for the 4th and 5th items.
603
604- Issue #4209: Enabling unicode_literals and the print_function in the same
605 __future__ import didn't work.
606
607- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
608 returned a path longer than MAX_PATH. (But It's doubtful this code path is
609 really executed because I cannot move to such directory on win2k)
610
611- Issue #4069: When set.remove(element) is used with a set element, the element
612 is temporarily replaced with an equivalent frozenset. But the eventual
613 KeyError would always report the empty frozenset([]) as the missing key. Now
614 it correctly refers to the initial element.
615
616- Fixed C99 style comments in several files. Python is now C89 compatible
617 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000764- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
765
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000766- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
767 PyString_FromFormat or PyErr_Format to display size_t values. The macro
768 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
769 ``printf`` function, whereas PyString_FromFormat has an independent
770 implementation and uses "%zd" on all platforms for size_t values.
771 This makes a difference on win64, where ``printf`` needs "%Id" to display
772 64bit values.
773
Benjamin Peterson97179b02008-09-09 20:55:01 +0000774- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000777- Issue #3777: long() applied to a float object now always return a long
778 object; previously an int would be returned for small values. the __long__
779 method is allowed to return either an int or a long, but the behaviour of
780 float objects should not change to respect backward compatibility.
781
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000782- Issue #3751: str.rpartition would perform a left-partition when called with
783 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000788 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000789 was correctly parsed but parsing of subsequent arguments failed.
790
Vinay Sajip35e3b032008-09-01 14:33:59 +0000791- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000792 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
793 mechanism. In the process, fix a bug where isinstance() and issubclass(),
794 when given a tuple of classes as second argument, were looking up
795 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
796 type object.
797
Neal Norwitz18aa3882008-08-24 05:04:52 +0000798- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +0000806- Silenced another compiler warning about a used but not defined
807 function 'stringlib_contains_obj'.

867 warnings.catch_warnings() along with some API cleanup. Expanding the tests
868 for catch_warnings() also led to an improvement in the raising of a
869 DeprecationWarning related to warnings.warn_explicit().

937Core and Builtins
938-----------------
939
Guido van Rossumf8402962008-08-20 15:01:50 +0000940- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
941 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
942 extensions do not automatically benefit from the class attribute
943 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
944 to their tp_flags field if they care. This is a backwards
945 compatibility feature; in 3.0, all types will use the cache by
946 default.
947
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000948- Keyword arguments can now follow starred arguments. (``f(a, *args,
949 keyword=23)`` is now valid syntax.)
950
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000951- ctypes function pointers that are COM methods have a boolean True
952 value again.
953
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000954- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
955 by denying s# to parse objects that have a releasebuffer procedure,
956 and introducing s*.
957
Georg Brandl1e13ea92008-08-11 09:07:59 +0000958- Issue #3537: Fix an assertion failure when an empty but presized dict
959 object was stored in the freelist.
960
Mark Dickinsonb6467572008-08-04 21:30:09 +0000961- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
962 ValueError consistently across platforms.
963
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000964- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
965 (64bit Unix, for example), unichr() would truncate its argument and return
966 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
967
Neal Norwitze7d8be82008-07-31 17:17:14 +0000968- Apply security patches from Apple.
969
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000970- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
971 PyErr_ExceptionMatches returns 0 when an exception occurs there.
972
Antoine Pitrou92f82162008-07-25 22:22:08 +0000973- Issue #1819: function calls with several named parameters are now on
974 average 35% faster (as measured by pybench).
975
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000976- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
977 the python debugger steps into a class statement: the free variables (local
978 variables defined in an outer scope) would be deleted from the outer scope.
979
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000980- Issue #2620: Overflow checking when allocating or reallocating memory
981 was not always being done properly in some python types and extension
982 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
983 all been updated to perform better checks and places in the code that
984 would previously leak memory on the error path when such an allocation
985 failed have been fixed.

991
Benjamin Petersone977ad42008-08-20 01:42:01 +0000992- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
993 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
994
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000995- Issue #2234: distutils failed for some versions of the cygwin compiler. The
996 version reported by these tools does not necessarily follow the python
997 version numbering scheme, so the module is less strict when parsing it.
998
Nick Coghlanf70385a2008-08-18 12:42:46 +0000999- Issue #2235: Added Py3k warnings for types which will become unhashable
1000 under the stricter __hash__ inheritance rules in 3.0. Several types
1001 which did not meet the rules for hash invariants and were already
1002 unhashable in 3.0 have now been explicitly flagged as unhashable in
1003 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1004 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1005
Brett Cannon88f801d2008-08-18 00:46:22 +00001006- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001015- Issue #3575: Incremental decoder's decode function now takes bytearray
1016 by using 's*' instead of 't#'.
1017
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001018- Issue #2222: Fixed reference leak when occured os.rename()
1019 fails unicode conversion on 2nd parameter. (windows only)
1020
Facundo Batista94f243a2008-08-17 03:38:39 +00001021- Issue 2464. urllib2 now supports a malformation in the URL received
1022 in a redirect.

Facundo Batistaeb90b782008-08-16 14:44:07 +00001027- Issue #2776: fixed small issue when handling an URL with double slash
1028 after a 302 response in the case of not going through a proxy.
1029
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001030- Issue #2676: in the email package, content-type parsing was hanging on
1031 pathological input because of quadratic or exponential behaviour of a
1032 regular expression.
1033
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001034- Issue #3476: binary buffered reading through the new "io" library is now
1035 thread-safe.
1036
Brett Cannonbf3157b2008-08-14 05:00:03 +00001037- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1038 since mimetools itself is deprecated. Because modules are cached, all
1039 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1040
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001041- Issue #3134: shutil referenced undefined WindowsError symbol.
1042
Robert Schuppenies14646332008-08-10 11:01:53 +00001043- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1044 menu entries were not deleted.
1045
Brett Cannon83e81842008-08-09 23:30:55 +00001046- Copied the implementation of reduce() to _functools.reduce() to have a
1047 version that did not raise a DeprecationWarning under -3.
1048
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001049- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1050 a MemoryError rather than silently stop the iteration.
1051
Guido van Rossum59ce9012008-08-09 14:55:34 +00001052- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1053 to _sre.compile() will now be rejected. This should not affect anybody
1054 since the re.compile() function never generates invalid re-bytecode.
1055
Skip Montanaroa032bf42008-08-08 22:52:51 +00001056- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1057 upon first access it can be automatically initialized from the csv file if
1058 it wasn't initialized during instantiation.
1059
Brett Cannon3aa2a492008-08-06 22:28:09 +00001060- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1061 the reload() built-in has been removed.
1062
Brett Cannon7e30b672008-08-04 21:52:25 +00001063- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001064 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1072 raised an AttributeError.
1073
Benjamin Peterson01a24322008-07-28 23:35:27 +00001074- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001075 asking for a specific length. This problem only affected files opened
1076 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001077
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001078- Issue #3449: Update decimal module to use most recent specification

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001101- Issue #3394: zipfile.writestr sets external attributes when passed a
1102 file name rather than a ZipInfo instance, so files are extracted with
1103 mode 0600 rather than 000 under Unix.
1104
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001105- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1106 argument in python 2.5, this broke code that subclassed Popen to include its

1118 interaction with the tp_hash slot (added in 2.6b2) are now documented
1119
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001120- Issue #643841: The language reference now provides more detailed
1121 coverage of the lookup process for special methods. The disclaimers
1122 regarding lack of coverage of new-style classes have also been
1123 removed, since the coverage is now fairly reasonable.

1127================================
1128
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001129*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001131Core and Builtins
1132-----------------
1133
Georg Brandl3e483f62008-07-16 22:57:41 +00001134- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1135 its methods now allow for items objects that can be converted to
1136 an integer using operator.index().
1137
Mark Dickinson64b7e502008-07-16 09:40:03 +00001138- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1139 produced a ValueError instead of giving the correct float.
1140
Eric Smitha5fa5a22008-07-16 00:11:49 +00001141- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1142 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1143
Mark Dickinson7103aa42008-07-15 19:08:33 +00001144- Issue #3008: the float type has a new instance method 'float.hex'
1145 and a new class method 'float.fromhex' to convert floating-point
1146 numbers to and from hexadecimal strings, respectively.
1147
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001148- Issue #2235: __hash__ is once again inherited by default. To allow
1149 collections.Hashable to remain meaningful in the presence of the
1150 default hash implementation (object.__hash__), it is now possible
1151 to explicit block inheritance of hash by setting __hash__=None at
1152 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1153 level.
1154
Nick Coghlanb028f502008-07-13 14:52:36 +00001155- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1156 the parent module cannot be found while performing an absolute import.
1157 This means that an incorrectly defined __package__ attribute will
1158 now only prevent relative imports in that module rather than causing
1159 all imports from that module to fail.
1160
Nick Coghlan14ff9942008-07-08 14:21:42 +00001161- Issue #2517: Allow unicode messages in Exceptions again by correctly
1162 bypassing the instance dictionary when looking up __unicode__ on
1163 new-style classes.
1164
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001165- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1166 set to a custom object whose write() method happens to install
1167 another file in sys.stdout.
1168
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001169- Issue #3088: Corrected a race condition in classes derived from
1170 threading.local: the first member set by a thread could be saved in
1171 another thread's dictionary.
1172
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001173- Issue #3004: Minor change to slice.indices(): the start and stop
1174 arguments are now treated identically, making the behaviour easier
1175 to describe and understand. For example, slice(None, -10,
1176 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1177 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1178 10, -1).
1179
Georg Brandl278fc502008-07-19 12:46:12 +00001180- Issue #3219: Calling a function with repeated keyword arguments,
1181 f(a=2, a=23), would not cause a syntax error. This was a regression
1182 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001183
Georg Brandl278fc502008-07-19 12:46:12 +00001184- Issue #2862: Make int and float freelist management consistent with
1185 other freelists. Changes their CompactFreeList apis into
1186 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001187

1190
Thomas Heller57adf222008-08-14 19:10:48 +00001191- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1192 api functions without holding the GIL, which could lead to a fatal
1193 error when they failed.
1194
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001195- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001203- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1204 ForkingPickler.register() to resolve conflict with ctypes.
1205
Vinay Sajip51e65192008-07-18 09:01:10 +00001206- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001207
Thomas Heller880f5292008-07-15 19:39:38 +00001208- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1209 a valid dlerror() message.
1210
Thomas Heller2bad6572008-07-15 17:19:50 +00001211- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1212 incomplete structure was created.
1213

1217
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001218- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001219
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001220- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1221 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001222 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001223 content-length. The problem had been corrected in the 2.4 branch, but never
1224 merged into trunk.
1225
Georg Brandle78fbcc2008-07-05 10:13:36 +00001226- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001239- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1240 handling is now the same as that of other special attributes like __name__).
1241
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001242- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1243 removal in Python 3.0 in favor of urllib2.urlopen().

1631 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001632 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001633
1634 This is controlled by the configure argument ``--with-universal-archs``:
1635
1636 - ``--with-universal-archs=all``: install 4-way universal
1637
1638 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1639
1640 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1641
1642 This option should be used in combination with ``--enable-universalsdk=``.
1643
1644 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 +00001694- Issue #1631171: Re-implement the 'warnings' module in C (the
1695 original Python code has been kept as backup). This will allow for
1696 using the 'warning's machinery in such places as the parser where
1697 use of pure Python code is not possible. Both the ``showarning()``
1698 and ``formatwarning()`` gain an optional 'line' argument which is
1699 not called by default for backwards-compatibility reasons. Setting
1700 ``warnings.showwarning()`` to an implementation that lacks support
1701 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001764- Issue #2550: The approach used by client/server code for obtaining
1765 ports to listen on in network-oriented tests has been refined in an
1766 effort to facilitate running multiple instances of the entire
1767 regression test suite in parallel without issue.
1768 test_support.bind_port() has been fixed such that it will always
1769 return a unique port -- which wasn't always the case with the
1770 previous implementation, especially if socket options had been set
1771 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1772 new implementation of bind_port() will actually raise an exception
1773 if it is passed an AF_INET/SOCK_STREAM socket with either the
1774 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1775 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1776 the socket it's been passed. This currently only applies to
1777 Windows. This option prevents any other sockets from binding to the
1778 host/port we've bound to, thus removing the possibility of the
1779 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1780 when a second SOCK_STREAM socket binds and accepts to a host/port
1781 that's already been bound by another socket. The optional preferred
1782 port parameter to bind_port() has been removed. Under no
1783 circumstances should tests be hard coding ports!
1784
1785 test_support.find_unused_port() has also been introduced, which will
1786 pass a temporary socket object to bind_port() in order to obtain an
1787 unused port. The temporary socket object is then closed and
1788 deleted, and the port is returned. This method should only be used
1789 for obtaining an unused port in order to pass to an external program
1790 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1791 a parameter to a server-oriented class that doesn't give you direct
1792 access to the underlying socket used.
1793
1794 Finally, test_support.HOST has been introduced, which should be used
1795 for the host argument of any relevant socket calls (i.e. bind and
1796 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001797
1798 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001799 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001800 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1801 test_asynchat and test_socket_ssl.
1802
Georg Brandl3ee81df2008-05-17 18:14:43 +00001803 It is now possible for multiple instances of the regression test
1804 suite to run in parallel without issue.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002080- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002081 issue 215555 for a discussion.
2082
Eric Smitha73fbe72008-02-23 03:09:44 +00002083- Added the future_builtins module, which contains hex() and oct().
2084 These are the PEP 3127 version of these functions, designed to be
2085 compatible with the hex() and oct() builtins from Python 3.0. They
2086 differ slightly in their output formats from the existing, unchanged
2087 Python 2.6 builtins. The expected usage of the future_builtins
2088 module is:
2089 from future_builtins import hex, oct
2090
Eric Smith7ef40bf2008-02-20 23:34:22 +00002091- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2092 exponents for exponents with absolute value < 100. Follows C99
2093 standard. This is a change on Windows, which would use 3 digits.
2094 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2095 so that any alterations it does to the resulting string will be
2096 available in stringlib/formatter.h (for float.__format__).
2097
Eric Smith5a3c1352008-02-19 13:21:56 +00002098- Implemented PEP 3101, Advanced String Formatting. This adds a new
2099 builtin format(); a format() method for str and unicode; a
2100 __format__() method to object, str, unicode, int, long, float, and
2101 datetime; the class string.Formatter; and the C API
2102 PyObject_Format().
2103
Georg Brandl3ee81df2008-05-17 18:14:43 +00002104- Fixed several potential crashes, all caused by specially crafted
2105 __del__ methods exploiting objects in temporarily inconsistent
2106 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002107
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002108- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002109 prevent a possible crash: an Abstract Base Class would try to access
2110 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002111
Georg Brandl3ee81df2008-05-17 18:14:43 +00002112- Fixed repr() and str() of complex numbers with infinity or nan as
2113 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002114
Georg Brandl3ee81df2008-05-17 18:14:43 +00002115- Clear all free lists during a gc.collect() of the highest generation
2116 in order to allow pymalloc to free more arenas. Python may give back
2117 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002118
Georg Brandl3ee81df2008-05-17 18:14:43 +00002119- Issue #2045: Fix an infinite recursion triggered when printing a
2120 subclass of collections.defaultdict, if its default_factory is set
2121 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002122
Christian Heimesf75dbef2008-02-08 00:11:31 +00002123- Fixed a minor memory leak in dictobject.c. The content of the free
2124 list was not freed on interpreter shutdown.
2125
Georg Brandl3ee81df2008-05-17 18:14:43 +00002126- Limit free list of method and builtin function objects to 256
2127 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002128
Georg Brandl3ee81df2008-05-17 18:14:43 +00002129- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2130 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002131 to compact the internal free lists of pre-allocted ints and floats.
2132
Georg Brandl3ee81df2008-05-17 18:14:43 +00002133- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2134 calls. Python expected the return type int but the fork familie
2135 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002136
Georg Brandl3ee81df2008-05-17 18:14:43 +00002137- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2138 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002139
Georg Brandl3ee81df2008-05-17 18:14:43 +00002140- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2141 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002142
Georg Brandl3ee81df2008-05-17 18:14:43 +00002143- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2144 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002145
Georg Brandl3ee81df2008-05-17 18:14:43 +00002146- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2147 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002148
Georg Brandl3ee81df2008-05-17 18:14:43 +00002149- Patch #1473257: generator objects gain a gi_code attribute. This is
2150 the same object as the func_code attribute of the function that
2151 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002152
Georg Brandl3ee81df2008-05-17 18:14:43 +00002153- Issue #1920: "while 0" statements were completely removed by the
2154 compiler, even in the presence of an "else" clause, which is
2155 supposed to be run when the condition is false. Now the compiler
2156 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002157
Guido van Rossumeead05f2008-01-24 18:21:02 +00002158- A few crashers fixed: weakref_in_del.py (issue #1377858);
2159 loosing_dict_ref.py (issue #1303614, test67.py);
2160 borrowed_ref_[34].py (not in tracker).
2161
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002162- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002163 suppressed while an extension is loaded by calling SetErrorMode in
2164 dynload_win.c. The error is still reported properly.
2165
Georg Brandl3ee81df2008-05-17 18:14:43 +00002166- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002167 several extension methods and modules do not work without unicode
2168 support.
2169
Georg Brandl26543b12008-01-21 18:36:51 +00002170- Issue #1882: when compiling code from a string, encoding cookies in the
2171 second line of code were not always recognized correctly.
2172
Georg Brandl14404b62008-01-19 19:27:05 +00002173- Issue #1679: "0x" was taken as a valid integer literal.
2174
Georg Brandl6caad7d2008-01-26 14:19:22 +00002175- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002176 added.
2177
Christian Heimesc94e2b52008-01-14 04:13:37 +00002178- sys.float_info / PyFloat_GetInfo: The floating point information
2179 object was converted from a dict to a specialized structseq object.
2180
Georg Brandl3ee81df2008-05-17 18:14:43 +00002181- Patch #1816: Added sys.flags structseq. It exposes the status of
2182 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002183
Georg Brandl3ee81df2008-05-17 18:14:43 +00002184- Objects/structseq.c: Implemented new structseq representation. The
2185 patch makes structseqs (e.g. the return value of os.stat) more
2186 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002187
Georg Brandl3ee81df2008-05-17 18:14:43 +00002188- Patch #1700288: added a type attribute cache that caches method
2189 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002190
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002191- Bug #1776: __import__() no longer accepts filenames on any platform.
2192 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002193
Georg Brandlaed6c662008-01-07 17:25:53 +00002194- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2195
Georg Brandl3ee81df2008-05-17 18:14:43 +00002196- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2197 envvar and sys.dont_write_bytecode attribute. All these can be set
2198 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002199
Georg Brandl3ee81df2008-05-17 18:14:43 +00002200- Improve some exception messages when Windows fails to load an
2201 extension module. Now we get for example '%1 is not a valid Win32
2202 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002203
Georg Brandl3ee81df2008-05-17 18:14:43 +00002204- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00002205
Georg Brandl3ee81df2008-05-17 18:14:43 +00002206- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2207 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002208
Christian Heimes0a8143f2007-12-18 23:22:54 +00002209- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002210 and INF. float("nan"), float("inf") and float("-inf") now work on
2211 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002212
Georg Brandl3ee81df2008-05-17 18:14:43 +00002213- Compiler now generates simpler and faster code for dictionary
2214 literals. The oparg for BUILD_MAP now indicates an estimated
2215 dictionary size. There is a new opcode, STORE_MAP, for adding
2216 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002217
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002220- Issue #1620: New property decorator syntax was modifying the
2221 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002222
Georg Brandl3ee81df2008-05-17 18:14:43 +00002223- Issue #1538: Avoid copying string in split/rsplit if the split char
2224 is not found.

2234 running, and if the deallocation of its frames somehow calls the
2235 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002236

2246 file can now be directly executed by passing their name to the
2247 interpreter. The directory/zipfile is automatically inserted as the
2248 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002249
Georg Brandl3ee81df2008-05-17 18:14:43 +00002250- Issue #1265: Fix a problem with sys.settrace, if the tracing
2251 function uses a generator expression when at the same time the
2252 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002253
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002254- sets and frozensets now have an isdisjoint() method.
2255
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002256- optimize the performance of builtin.sum().
2257
Neal Norwitz44f326e2007-10-05 05:29:17 +00002258- Fix warnings found by the new version of the Coverity checker.
2259
Georg Brandl3ee81df2008-05-17 18:14:43 +00002260- The enumerate() builtin function is no longer bounded to sequences
2261 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2262 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002263
Georg Brandl3ee81df2008-05-17 18:14:43 +00002264- Issue #1686386: Tuple's tp_repr did not take into account the
2265 possibility of having a self-referential tuple, which is possible
2266 from C code. Nor did object's tp_str consider that a type's tp_str
2267 could do something that could lead to an inifinite recursion.
2268 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2269 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002270
Georg Brandl3ee81df2008-05-17 18:14:43 +00002271- Issue #1164: It was possible to trigger deadlock when using the
2272 'print' statement to write to a file since the GIL was not released
2273 as needed. Now PyObject_Print() does the right thing along with
2274 various tp_print implementations of the built-in types and those in
2275 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002276
Georg Brandl3ee81df2008-05-17 18:14:43 +00002277- Issue #1147: Exceptions were directly allowing string exceptions in
2278 their throw() method even though string exceptions no longer
2279 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002280
Georg Brandl3ee81df2008-05-17 18:14:43 +00002281- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002284- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002285 PyObject_Call() never calling back out to Python code to trigger
2286 recursion depth updates/checks. Required the creation of a static
2287 RuntimeError instance in case normalizing an exception put the
2288 recursion check value past its limit. Fixes crashers
2289 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002290
Georg Brandl3ee81df2008-05-17 18:14:43 +00002291- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002304- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002305 __*__ attributes. (Some already existed, e.g., __doc__ and
2306 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002307
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002308- Add -3 option to the interpreter to warn about features that are
2309 deprecated and will be changed/removed in Python 3.0.
2310
Georg Brandl2134e752007-05-21 20:34:16 +00002311- Patch #1686487: you can now pass any mapping after '**' in function
2312 calls.
2313
Collin Winter62903052007-05-18 23:11:24 +00002314- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002315 "except E as target:". This is to provide forwards compatibility
2316 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002317
Brett Cannon229cee22007-05-05 01:34:02 +00002318- Deprecate BaseException.message as per PEP 352.
2319
Georg Brandl3ee81df2008-05-17 18:14:43 +00002320- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002321 inherited from a builtin base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00002323- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002324 setting a plain string, ie don't expand to single letter identifiers.

Raymond Hettinger13936692007-04-11 18:40:58 +00002326- Request #1191699: Slices can now be pickled.
2327

2329 translations that only remove characters without re-mapping the
2330 remaining characters.
2331
Georg Brandl5cb76c12007-03-21 09:00:39 +00002332- Patch #1682205: a TypeError while unpacking an iterable is no longer

2336
Guido van Rossum143b5642007-03-23 04:58:42 +00002337- Bug #1683368: The object.__init__() and object.__new__() methods are
2338 now stricter in rejecting excess arguments. The only time when
2339 either allows excess arguments is when it is not overridden and the
2340 other one is. For backwards compatibility, when both are
2341 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002342 warning later). Also, type.__init__() insists on the same signature
2343 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002345- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2346 object to complex using its __complex__() method before falling back
2347 to the __float__() method. Therefore, the functions in the cmath
2348 module now can operate on objects that define a __complex__()
2349 method.

2366
Georg Brandl7b9c5552007-03-12 14:30:05 +00002367- Bug #1678647: write a newline after printing an exception in any
2368 case, even when converting the value to a string failed.
2369
Georg Brandl871f1bc2007-03-12 13:17:36 +00002370- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002371 its argument, if it exists. If not, it will work like before. This
2372 allows customizing the output of dir() in the presence of a
2373 __getattr__().

2383 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002384
Georg Brandlaa2321b2007-03-07 00:40:28 +00002385- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002386 makes the filenames the warning module prints much more sensible
2387 when a PYTHONSTARTUP file is used.

2401 sq_ass_slice instead of the sq_slice slot.
2402
Georg Brandl3ee81df2008-05-17 18:14:43 +00002403- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00002455- Bug #1545497: when given an explicit base, int() did ignore NULs
2456 embedded in the string to convert.
2457
Georg Brandl846f73a2006-10-08 07:11:54 +00002458- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002506 generator expressions (x for x, in ... ) works again. Fixing this
2507 problem required changing the .pyc magic number. This means that
2508 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00002547- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00002938 AttributeError instead of an IOError when the server's response
2939 didn't contain a valid HTTP status line.

3017 returned string up to the first NUL character.

3028
Georg Brandl3ee81df2008-05-17 18:14:43 +00003029- unittest now verifies more of its assumptions. In particular,
3030 TestCase and TestSuite subclasses (not instances) are no longer
3031 accepted in TestSuite.addTest(). This should cause no
3032 incompatibility since it never made sense with ordinary subclasses
3033 -- the failure just occurred later, with a more cumbersome
3034 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003311- The implementation of UnicodeError objects has been simplified
3312 (start and end attributes are now stored directly as Py_ssize_t
3313 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003314
Georg Brandl3ee81df2008-05-17 18:14:43 +00003315- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3316 with RFC 3207 and forgets any knowledge obtained from the server not
3317 obtained from the TLS negotiation itself. Patch contributed by Bill
3318 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003319
Georg Brandl3ee81df2008-05-17 18:14:43 +00003320- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003321 that the SMTP.starttls() caller no longer needs to call ehlo()
3322 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003323 does not claim to support starttls. Adds the
3324 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3325 Fenner.

3405 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3406 silently miscode subclasses of those types. Now, it raises a
3407 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003408

Georg Brandl3ee81df2008-05-17 18:14:43 +00003423 time so that opening a database previously created with the DB_DUP
3424 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3425 opens. Specifically: dictionary assignment to a DB object will
3426 replace all values for a given key when the database allows
3427 duplicate values. DB users should use DB.put(k, v) when they want
3428 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003429

3435 characters with ASCII value less than 32. Also, it correctly quotes
3436 dots only if they occur on a single line, as opposed to the previous
3437 behavior of quoting dots if they are the second character of any
3438 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003439

Georg Brandl3ee81df2008-05-17 18:14:43 +00003844- Removed the macfs module. It had been deprecated since Python 2.5.
3845 This lead to the deprecation of macostools.touched() as it relied
3846 solely on macfs and was a no-op under OS X.
