494What's New in Python 2.6.1
495==========================
496
497*Release date: 04-Dec-2008*
498
499Core and Builtins
500-----------------
501
502- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
503 interpreter to abort ("Fatal Python error: Could not reset the stack!")
504 instead of throwing a MemoryError.
505
506- Issue #4367: Python would segfault during compiling when the unicodedata
507 module couldn't be imported and \N escapes were present.
508
509- Issue #4348: Some bytearray methods returned that didn't cause any change to
510 the bytearray, returned the same bytearray instead of a copy.
511
512- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
513
514- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
515
516- Issue #4048: The parser module now correctly validates relative imports.
517
518- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

523
524- Issue #4209: Enabling unicode_literals and the print_function in the same
525 __future__ import didn't work.
526
527- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
528 returned a path longer than MAX_PATH. (But It's doubtful this code path is
529 really executed because I cannot move to such directory on win2k)
530
531- Issue #4069: When set.remove(element) is used with a set element, the element
532 is temporarily replaced with an equivalent frozenset. But the eventual
533 KeyError would always report the empty frozenset([]) as the missing key. Now
534 it correctly refers to the initial element.
535
536- Fixed C99 style comments in several files. Python is now C89 compatible
537 again.

681Core and Builtins
682-----------------
683
Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000684- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
685
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000686- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
687 PyString_FromFormat or PyErr_Format to display size_t values. The macro
688 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
689 ``printf`` function, whereas PyString_FromFormat has an independent
690 implementation and uses "%zd" on all platforms for size_t values.
691 This makes a difference on win64, where ``printf`` needs "%Id" to display
692 64bit values.
693
Benjamin Peterson97179b02008-09-09 20:55:01 +0000694- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
695 error.
696
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000697- Issue #3777: long() applied to a float object now always return a long
698 object; previously an int would be returned for small values. the __long__
699 method is allowed to return either an int or a long, but the behaviour of
700 float objects should not change to respect backward compatibility.
701
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000702- Issue #3751: str.rpartition would perform a left-partition when called with
703 a unicode argument.
704
Benjamin Peterson17f03ca2008-09-01 14:18:30 +0000705- Issue #3683: Fix compilation when --without-threads is given.
706
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000707- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +0000708 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000709 was correctly parsed but parsing of subsequent arguments failed.
710
Vinay Sajip35e3b032008-09-01 14:33:59 +0000711- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000712 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
713 mechanism. In the process, fix a bug where isinstance() and issubclass(),
714 when given a tuple of classes as second argument, were looking up
715 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
716 type object.
717
Neal Norwitz18aa3882008-08-24 05:04:52 +0000718- Fix crashes on memory allocation failure found with failmalloc.
719
720- Fix memory leaks found with valgrind and update suppressions file.
721
722- Fix compiler warnings in opt mode which would lead to invalid memory reads.
723
724- Fix problem using wrong name in decimal module reported by pychecker.
725
Christian Heimes7d4c3172008-08-22 19:47:25 +0000726- Silenced another compiler warning about a used but not defined
727 function 'stringlib_contains_obj'.
728
Benjamin Peterson712ee922008-08-24 18:10:20 +0000729- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
730 ``__delslice__``.
731
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +0000732- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
733 library targets in the Makefile.
734
Gregory P. Smith980b99b2008-09-07 05:15:18 +0000735- Issue #1204: The configure script now tests for additional libraries
736 that may be required when linking against readline. This fixes issues
737 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
738
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +0000739C-API

745-------
746
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +0000747- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
748 stack usage in the case of deeply nested objects.
749
Guido van Rossume3c4fd92008-09-10 14:27:00 +0000750- Issue #3629: Fix sre "bytecode" validator for an end case.
751
Martin v. Löwis24329ba2008-09-10 13:38:12 +0000752- Issue #3811: The Unicode database was updated to 5.1.
753
Nick Coghland2e09382008-09-11 12:11:06 +0000754- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
755 silent misbehaviour when a single instance is nested in multiple
756 with statements, or when the methods are invoked in the wrong order.
757
Vinay Sajip844f7412008-09-09 13:42:08 +0000758- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.

762
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +0000763- Issue #1638033: Cookie.Morsel gained the httponly attribute.
764
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +0000765- Issue #3535: zipfile couldn't read some zip files larger than 2GB.
766
767- Issue #3776: Deprecate the bsddb package for removal in 3.0.
Brett Cannon32476fc2008-09-05 18:33:51 +0000768
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +0000769- Issue #3762: platform.architecture() fails if python is lanched via
770 its symbolic link.
771
Vinay Sajip65d66e12008-09-04 07:31:21 +0000772- Issue #3772: Fixed regression problem in StreamHandler.emit().

784 path to the Python binary.
785
Brett Cannon1eaf0742008-09-02 01:25:16 +0000786- Issue 3602: Moved test.test_support.catch_warning() to
787 warnings.catch_warnings() along with some API cleanup. Expanding the tests
788 for catch_warnings() also led to an improvement in the raising of a
789 DeprecationWarning related to warnings.warn_explicit().
790
Benjamin Peterson973e6c22008-09-01 23:12:58 +0000791- The deprecation warnings for the old camelCase threading API were removed.
792

Benjamin Peterson37346b22008-08-23 20:27:43 +0000808Extension Modules
809-----------------
810
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000811- Issue #2975: When compiling several extension modules with Visual Studio 2008

821 remaining ones have "pysqlite_" prefix.
822
Gerhard Häringe6872eb2008-09-12 22:33:22 +0000823- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000852What's New in Python 2.6 beta 3?
853================================
854
Barry Warsaw07a4a382008-08-21 01:15:08 +0000855*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000856
857Core and Builtins
858-----------------
859
Guido van Rossumf8402962008-08-20 15:01:50 +0000860- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
861 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
862 extensions do not automatically benefit from the class attribute
863 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
864 to their tp_flags field if they care. This is a backwards
865 compatibility feature; in 3.0, all types will use the cache by
866 default.
867
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000868- Keyword arguments can now follow starred arguments. (``f(a, *args,
869 keyword=23)`` is now valid syntax.)
870
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000871- ctypes function pointers that are COM methods have a boolean True
872 value again.
873
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000874- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
875 by denying s# to parse objects that have a releasebuffer procedure,
876 and introducing s*.
877
Georg Brandl1e13ea92008-08-11 09:07:59 +0000878- Issue #3537: Fix an assertion failure when an empty but presized dict
879 object was stored in the freelist.
880
Mark Dickinsonb6467572008-08-04 21:30:09 +0000881- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
882 ValueError consistently across platforms.
883
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000884- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
885 (64bit Unix, for example), unichr() would truncate its argument and return
886 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
887
Neal Norwitze7d8be82008-07-31 17:17:14 +0000888- Apply security patches from Apple.
889
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000890- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
891 PyErr_ExceptionMatches returns 0 when an exception occurs there.
892
Antoine Pitrou92f82162008-07-25 22:22:08 +0000893- Issue #1819: function calls with several named parameters are now on
894 average 35% faster (as measured by pybench).
895
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000896- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
897 the python debugger steps into a class statement: the free variables (local
898 variables defined in an outer scope) would be deleted from the outer scope.
899
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000900- Issue #2620: Overflow checking when allocating or reallocating memory
901 was not always being done properly in some python types and extension
902 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
903 all been updated to perform better checks and places in the code that
904 would previously leak memory on the error path when such an allocation
905 failed have been fixed.
906

908-------
909

Benjamin Petersone977ad42008-08-20 01:42:01 +0000912- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
913 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
914
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000915- Issue #2234: distutils failed for some versions of the cygwin compiler. The
916 version reported by these tools does not necessarily follow the python
917 version numbering scheme, so the module is less strict when parsing it.
918
Nick Coghlanf70385a2008-08-18 12:42:46 +0000919- Issue #2235: Added Py3k warnings for types which will become unhashable
920 under the stricter __hash__ inheritance rules in 3.0. Several types
921 which did not meet the rules for hash invariants and were already
922 unhashable in 3.0 have now been explicitly flagged as unhashable in
923 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
924 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
925
Brett Cannon88f801d2008-08-18 00:46:22 +0000926- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
927 imported into the module but exposed as part of the module's API.
928
Brett Cannon7b96f072008-08-18 00:41:11 +0000929- Remove an unneeded import of abc.ABCMeta from 'inspect'.

934
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000935- Issue #3575: Incremental decoder's decode function now takes bytearray
936 by using 's*' instead of 't#'.
937
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000938- Issue #2222: Fixed reference leak when occured os.rename()
939 fails unicode conversion on 2nd parameter. (windows only)
940
Facundo Batista94f243a2008-08-17 03:38:39 +0000941- Issue 2464. urllib2 now supports a malformation in the URL received
942 in a redirect.
943
Brett Cannonabe423e2008-08-16 21:47:07 +0000944- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000945 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000946
Facundo Batistaeb90b782008-08-16 14:44:07 +0000947- Issue #2776: fixed small issue when handling an URL with double slash
948 after a 302 response in the case of not going through a proxy.
949
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000950- Issue #2676: in the email package, content-type parsing was hanging on
951 pathological input because of quadratic or exponential behaviour of a
952 regular expression.
953
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000954- Issue #3476: binary buffered reading through the new "io" library is now
955 thread-safe.
956
Brett Cannonbf3157b2008-08-14 05:00:03 +0000957- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
958 since mimetools itself is deprecated. Because modules are cached, all
959 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
960
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000961- Issue #3134: shutil referenced undefined WindowsError symbol.
962
Robert Schuppenies14646332008-08-10 11:01:53 +0000963- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
964 menu entries were not deleted.
965
Brett Cannon83e81842008-08-09 23:30:55 +0000966- Copied the implementation of reduce() to _functools.reduce() to have a
967 version that did not raise a DeprecationWarning under -3.
968
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000969- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
970 a MemoryError rather than silently stop the iteration.
971
Guido van Rossum59ce9012008-08-09 14:55:34 +0000972- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
973 to _sre.compile() will now be rejected. This should not affect anybody
974 since the re.compile() function never generates invalid re-bytecode.
975
Skip Montanaroa032bf42008-08-08 22:52:51 +0000976- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
977 upon first access it can be automatically initialized from the csv file if
978 it wasn't initialized during instantiation.
979
Brett Cannon3aa2a492008-08-06 22:28:09 +0000980- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as

Antoine Pitroude781a42008-08-09 12:43:23 +0000995 asking for a specific length. This problem only affected files opened

1048
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001049*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001051Core and Builtins
1052-----------------
1053
Georg Brandl3e483f62008-07-16 22:57:41 +00001054- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1055 its methods now allow for items objects that can be converted to
1056 an integer using operator.index().
1057
Mark Dickinson64b7e502008-07-16 09:40:03 +00001058- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1059 produced a ValueError instead of giving the correct float.
1060
Eric Smitha5fa5a22008-07-16 00:11:49 +00001061- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1062 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1063
Mark Dickinson7103aa42008-07-15 19:08:33 +00001064- Issue #3008: the float type has a new instance method 'float.hex'
1065 and a new class method 'float.fromhex' to convert floating-point
1066 numbers to and from hexadecimal strings, respectively.
1067
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001068- Issue #2235: __hash__ is once again inherited by default. To allow
1069 collections.Hashable to remain meaningful in the presence of the
1070 default hash implementation (object.__hash__), it is now possible
1071 to explicit block inheritance of hash by setting __hash__=None at
1072 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1073 level.
1074
Nick Coghlanb028f502008-07-13 14:52:36 +00001075- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1076 the parent module cannot be found while performing an absolute import.
1077 This means that an incorrectly defined __package__ attribute will
1078 now only prevent relative imports in that module rather than causing
1079 all imports from that module to fail.
1080
Nick Coghlan14ff9942008-07-08 14:21:42 +00001081- Issue #2517: Allow unicode messages in Exceptions again by correctly

1086 set to a custom object whose write() method happens to install
1087 another file in sys.stdout.

1090 threading.local: the first member set by a thread could be saved in
1091 another thread's dictionary.
1092
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001093- Issue #3004: Minor change to slice.indices(): the start and stop
1094 arguments are now treated identically, making the behaviour easier
1095 to describe and understand. For example, slice(None, -10,
1096 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1097 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1098 10, -1).
1099
Georg Brandl278fc502008-07-19 12:46:12 +00001100- Issue #3219: Calling a function with repeated keyword arguments,
1101 f(a=2, a=23), would not cause a syntax error. This was a regression
1102 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001103
Georg Brandl278fc502008-07-19 12:46:12 +00001104- Issue #2862: Make int and float freelist management consistent with
1105 other freelists. Changes their CompactFreeList apis into
1106 ClearFreeList apis and calls them via gc.collect().

1112 api functions without holding the GIL, which could lead to a fatal
1113 error when they failed.
1114
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001115- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001140- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1141 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001142 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001143 content-length. The problem had been corrected in the 2.4 branch, but never
1144 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001159- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1160 handling is now the same as that of other special attributes like __name__).
1161
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001162- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00001550- On MacOS X it is now possible to install the framework in 64-bit
1551 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001552 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001553
1554 This is controlled by the configure argument ``--with-universal-archs``:
1555
1556 - ``--with-universal-archs=all``: install 4-way universal
1557
1558 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1559
1560 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1561
1562 This option should be used in combination with ``--enable-universalsdk=``.
1563
1564 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

1569
Georg Brandl74a1dea2008-05-28 11:21:39 +00001570- Add ``PyType_Modified()`` as a public API to clear the type cache.
1571
1572- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00001573
1574- The PyString functions have been renamed to PyBytes. A batch of
1575 defines were added so that the linker still sees the original
1576 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001614- Issue #1631171: Re-implement the 'warnings' module in C (the
1615 original Python code has been kept as backup). This will allow for
1616 using the 'warning's machinery in such places as the parser where
1617 use of pure Python code is not possible. Both the ``showarning()``
1618 and ``formatwarning()`` gain an optional 'line' argument which is
1619 not called by default for backwards-compatibility reasons. Setting
1620 ``warnings.showwarning()`` to an implementation that lacks support
1621 for the ``line`` argument will raise a DeprecationWarning.

1645
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001646- The getpass module has been improved on Unix. It now uses /dev/tty
1647 by default and uses stderr instead of stdout. A GetPassWarning is
1648 issued when input echo cannot be controlled.

1661 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00001662
Georg Brandl3ee81df2008-05-17 18:14:43 +00001663- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001664 extension modules between 32 and 64 bit platforms. See the distutls

1677 so the controlled environment will more closely mirror the typical
1678 script environment. This supports setup.py scripts that refer to
1679 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001684- Issue #2550: The approach used by client/server code for obtaining
1685 ports to listen on in network-oriented tests has been refined in an
1686 effort to facilitate running multiple instances of the entire
1687 regression test suite in parallel without issue.
1688 test_support.bind_port() has been fixed such that it will always
1689 return a unique port -- which wasn't always the case with the
1690 previous implementation, especially if socket options had been set
1691 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1692 new implementation of bind_port() will actually raise an exception
1693 if it is passed an AF_INET/SOCK_STREAM socket with either the
1694 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1695 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1696 the socket it's been passed. This currently only applies to
1697 Windows. This option prevents any other sockets from binding to the
1698 host/port we've bound to, thus removing the possibility of the
1699 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1700 when a second SOCK_STREAM socket binds and accepts to a host/port
1701 that's already been bound by another socket. The optional preferred
1702 port parameter to bind_port() has been removed. Under no
1703 circumstances should tests be hard coding ports!
1704
1705 test_support.find_unused_port() has also been introduced, which will
1706 pass a temporary socket object to bind_port() in order to obtain an
1707 unused port. The temporary socket object is then closed and
1708 deleted, and the port is returned. This method should only be used
1709 for obtaining an unused port in order to pass to an external program
1710 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1711 a parameter to a server-oriented class that doesn't give you direct
1712 access to the underlying socket used.
1713
1714 Finally, test_support.HOST has been introduced, which should be used
1715 for the host argument of any relevant socket calls (i.e. bind and
1716 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001717
1718 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001719 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001720 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1721 test_asynchat and test_socket_ssl.
1722
Georg Brandl3ee81df2008-05-17 18:14:43 +00001723 It is now possible for multiple instances of the regression test
1724 suite to run in parallel without issue.

1992
Fred Drakea8ee94b2008-03-01 02:45:07 +00001993- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001994 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002000- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002001 issue 215555 for a discussion.
2002
Eric Smitha73fbe72008-02-23 03:09:44 +00002003- Added the future_builtins module, which contains hex() and oct().
2004 These are the PEP 3127 version of these functions, designed to be
2005 compatible with the hex() and oct() builtins from Python 3.0. They
2006 differ slightly in their output formats from the existing, unchanged
2007 Python 2.6 builtins. The expected usage of the future_builtins
2008 module is:
2009 from future_builtins import hex, oct
2010
Eric Smith7ef40bf2008-02-20 23:34:22 +00002011- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2012 exponents for exponents with absolute value < 100. Follows C99
2013 standard. This is a change on Windows, which would use 3 digits.
2014 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2015 so that any alterations it does to the resulting string will be
2016 available in stringlib/formatter.h (for float.__format__).
2017
Eric Smith5a3c1352008-02-19 13:21:56 +00002018- Implemented PEP 3101, Advanced String Formatting. This adds a new
2019 builtin format(); a format() method for str and unicode; a
2020 __format__() method to object, str, unicode, int, long, float, and
2021 datetime; the class string.Formatter; and the C API
2022 PyObject_Format().
2023
Georg Brandl3ee81df2008-05-17 18:14:43 +00002024- Fixed several potential crashes, all caused by specially crafted
2025 __del__ methods exploiting objects in temporarily inconsistent
2026 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002027
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002028- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002029 prevent a possible crash: an Abstract Base Class would try to access
2030 a slot on a registered virtual subclass.

2037 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002038
Georg Brandl3ee81df2008-05-17 18:14:43 +00002039- Issue #2045: Fix an infinite recursion triggered when printing a
2040 subclass of collections.defaultdict, if its default_factory is set
2041 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002042
Christian Heimesf75dbef2008-02-08 00:11:31 +00002043- Fixed a minor memory leak in dictobject.c. The content of the free
2044 list was not freed on interpreter shutdown.
2045
Georg Brandl3ee81df2008-05-17 18:14:43 +00002046- Limit free list of method and builtin function objects to 256
2047 entries each.

2050 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002051 to compact the internal free lists of pre-allocted ints and floats.
2052
Georg Brandl3ee81df2008-05-17 18:14:43 +00002053- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2054 calls. Python expected the return type int but the fork familie
2055 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002056

Georg Brandl3ee81df2008-05-17 18:14:43 +00002069- Patch #1473257: generator objects gain a gi_code attribute. This is
2070 the same object as the func_code attribute of the function that
2071 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002072
Georg Brandl3ee81df2008-05-17 18:14:43 +00002073- Issue #1920: "while 0" statements were completely removed by the
2074 compiler, even in the presence of an "else" clause, which is
2075 supposed to be run when the condition is false. Now the compiler
2076 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002077
Guido van Rossumeead05f2008-01-24 18:21:02 +00002078- A few crashers fixed: weakref_in_del.py (issue #1377858);
2079 loosing_dict_ref.py (issue #1303614, test67.py);
2080 borrowed_ref_[34].py (not in tracker).
2081
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002082- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002083 suppressed while an extension is loaded by calling SetErrorMode in
2084 dynload_win.c. The error is still reported properly.
2085
Georg Brandl3ee81df2008-05-17 18:14:43 +00002086- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002087 several extension methods and modules do not work without unicode
2088 support.
2089
Georg Brandl26543b12008-01-21 18:36:51 +00002090- Issue #1882: when compiling code from a string, encoding cookies in the
2091 second line of code were not always recognized correctly.
2092
Georg Brandl14404b62008-01-19 19:27:05 +00002093- Issue #1679: "0x" was taken as a valid integer literal.
2094
Georg Brandl6caad7d2008-01-26 14:19:22 +00002095- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002096 added.
2097
Christian Heimesc94e2b52008-01-14 04:13:37 +00002098- sys.float_info / PyFloat_GetInfo: The floating point information
2099 object was converted from a dict to a specialized structseq object.
2100
Georg Brandl3ee81df2008-05-17 18:14:43 +00002101- Patch #1816: Added sys.flags structseq. It exposes the status of
2102 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002103
Georg Brandl3ee81df2008-05-17 18:14:43 +00002104- Objects/structseq.c: Implemented new structseq representation. The
2105 patch makes structseqs (e.g. the return value of os.stat) more
2106 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002107
Georg Brandl3ee81df2008-05-17 18:14:43 +00002108- Patch #1700288: added a type attribute cache that caches method
2109 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002110
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002111- Bug #1776: __import__() no longer accepts filenames on any platform.
2112 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002113
Georg Brandlaed6c662008-01-07 17:25:53 +00002114- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2115
Georg Brandl3ee81df2008-05-17 18:14:43 +00002116- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2117 envvar and sys.dont_write_bytecode attribute. All these can be set
2118 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002119
Georg Brandl3ee81df2008-05-17 18:14:43 +00002120- Improve some exception messages when Windows fails to load an
2121 extension module. Now we get for example '%1 is not a valid Win32
2122 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002123
Georg Brandl3ee81df2008-05-17 18:14:43 +00002124- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002126- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2127 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002128
Christian Heimes0a8143f2007-12-18 23:22:54 +00002129- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002130 and INF. float("nan"), float("inf") and float("-inf") now work on
2131 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002132
Georg Brandl3ee81df2008-05-17 18:14:43 +00002133- Compiler now generates simpler and faster code for dictionary
2134 literals. The oparg for BUILD_MAP now indicates an estimated
2135 dictionary size. There is a new opcode, STORE_MAP, for adding
2136 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002137
Georg Brandl3ee81df2008-05-17 18:14:43 +00002138- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002143- Issue #1538: Avoid copying string in split/rsplit if the split char
2144 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002145
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002146- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002147 SystemError.
2148
Nick Coghlanef01d822007-12-03 12:55:17 +00002149- PEP 366: Allow explicit relative imports when executing modules

2154 running, and if the deallocation of its frames somehow calls the
2155 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002156

2161
Georg Brandl3ee81df2008-05-17 18:14:43 +00002162- Issue #1460: The utf-7 incremental decoder did not accept truncated
2163 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002164
Georg Brandl3ee81df2008-05-17 18:14:43 +00002165- Patch #1739468: Directories and zipfiles containing a __main__.py
2166 file can now be directly executed by passing their name to the
2167 interpreter. The directory/zipfile is automatically inserted as the
2168 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002169
Georg Brandl3ee81df2008-05-17 18:14:43 +00002170- Issue #1265: Fix a problem with sys.settrace, if the tracing
2171 function uses a generator expression when at the same time the
2172 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002173
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002174- sets and frozensets now have an isdisjoint() method.
2175
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002176- optimize the performance of builtin.sum().
2177
Neal Norwitz44f326e2007-10-05 05:29:17 +00002178- Fix warnings found by the new version of the Coverity checker.
2179
Georg Brandl3ee81df2008-05-17 18:14:43 +00002180- The enumerate() builtin function is no longer bounded to sequences
2181 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2182 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002183
Georg Brandl3ee81df2008-05-17 18:14:43 +00002184- Issue #1686386: Tuple's tp_repr did not take into account the
2185 possibility of having a self-referential tuple, which is possible
2186 from C code. Nor did object's tp_str consider that a type's tp_str
2187 could do something that could lead to an inifinite recursion.
2188 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2189 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002190
Georg Brandl3ee81df2008-05-17 18:14:43 +00002191- Issue #1164: It was possible to trigger deadlock when using the
2192 'print' statement to write to a file since the GIL was not released
2193 as needed. Now PyObject_Print() does the right thing along with
2194 various tp_print implementations of the built-in types and those in
2195 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002196
Georg Brandl3ee81df2008-05-17 18:14:43 +00002197- Issue #1147: Exceptions were directly allowing string exceptions in
2198 their throw() method even though string exceptions no longer
2199 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002200
Georg Brandl3ee81df2008-05-17 18:14:43 +00002201- Issue #1096: Prevent a segfault from getting the repr of a very
2202 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002203
Brett Cannon1e534b52007-09-07 04:18:30 +00002204- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002205 PyObject_Call() never calling back out to Python code to trigger
2206 recursion depth updates/checks. Required the creation of a static
2207 RuntimeError instance in case normalizing an exception put the
2208 recursion check value past its limit. Fixes crashers
2209 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002210
Georg Brandl3ee81df2008-05-17 18:14:43 +00002211- Patch #1031213: Decode source line in SyntaxErrors back to its

2215 with %G.
2216
Georg Brandl3ee81df2008-05-17 18:14:43 +00002217- Prevent expandtabs() on string and unicode objects from causing a
2218 segfault when a large width is passed on 32-bit platforms.

Georg Brandla5ea6892007-06-01 11:33:33 +00002223
Neal Norwitz0ac60192007-05-27 04:08:54 +00002224- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002225 __*__ attributes. (Some already existed, e.g., __doc__ and
2226 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002227
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002228- Add -3 option to the interpreter to warn about features that are
2229 deprecated and will be changed/removed in Python 3.0.
2230
Georg Brandl2134e752007-05-21 20:34:16 +00002231- Patch #1686487: you can now pass any mapping after '**' in function
2232 calls.
2233
Collin Winter62903052007-05-18 23:11:24 +00002234- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002235 "except E as target:". This is to provide forwards compatibility
2236 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002237
Brett Cannon229cee22007-05-05 01:34:02 +00002238- Deprecate BaseException.message as per PEP 352.
2239
Georg Brandl3ee81df2008-05-17 18:14:43 +00002240- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002241 inherited from a builtin base.
2242
Vinay Sajip8549ce32007-05-06 17:53:37 +00002243- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002244 setting a plain string, ie don't expand to single letter identifiers.
2245
Raymond Hettinger13936692007-04-11 18:40:58 +00002246- Request #1191699: Slices can now be pickled.
2247
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002248- Request #1193128: str.translate() now allows a None argument for
2249 translations that only remove characters without re-mapping the
2250 remaining characters.
2251
Georg Brandl5cb76c12007-03-21 09:00:39 +00002252- Patch #1682205: a TypeError while unpacking an iterable is no longer
2253 masked by a generic one with the message "unpack non-sequence".
2254
Neal Norwitzaa754b72007-03-21 06:39:48 +00002255- Remove unused file Python/fmod.c.
2256
Guido van Rossum143b5642007-03-23 04:58:42 +00002257- Bug #1683368: The object.__init__() and object.__new__() methods are
2258 now stricter in rejecting excess arguments. The only time when
2259 either allows excess arguments is when it is not overridden and the
2260 other one is. For backwards compatibility, when both are
2261 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002262 warning later). Also, type.__init__() insists on the same signature
2263 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002264
Georg Brandl3ee81df2008-05-17 18:14:43 +00002265- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2266 object to complex using its __complex__() method before falling back
2267 to the __float__() method. Therefore, the functions in the cmath
2268 module now can operate on objects that define a __complex__()
2269 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002270
Georg Brandl3ee81df2008-05-17 18:14:43 +00002271- Patch #1623563: allow __class__ assignment for classes with
2272 __slots__. The old and the new class are still required to have the
2273 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002274
Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002278- Patch #1462488: Python no longer segfaults when
2279 ``object.__reduce_ex__()`` is called with an object that is faking
2280 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002281
Georg Brandl3ee81df2008-05-17 18:14:43 +00002282- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002285- Patch #1444529: the builtin compile() now accepts keyword arguments.
2286
Georg Brandl7b9c5552007-03-12 14:30:05 +00002287- Bug #1678647: write a newline after printing an exception in any
2288 case, even when converting the value to a string failed.
2289
Georg Brandl871f1bc2007-03-12 13:17:36 +00002290- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002291 its argument, if it exists. If not, it will work like before. This
2292 allows customizing the output of dir() in the presence of a
2293 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002294
Collin Winter276887b2007-03-12 16:11:39 +00002295- Patch #922167: Python no longer segfaults when faced with infinitely
2296 self-recursive reload() calls (as reported by bug #742342).
2297
Georg Brandl3ee81df2008-05-17 18:14:43 +00002298- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002301- Patch #1491866: change the complex() constructor to allow
2302 parthensized forms. This means complex(repr(x)) now works instead of
2303 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002304
Georg Brandlaa2321b2007-03-07 00:40:28 +00002305- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002306 makes the filenames the warning module prints much more sensible
2307 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002308

2815
Facundo Batistad918a652007-04-24 13:54:38 +00002816- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002817 the client's request was successfully received, understood, and
2818 accepted. Now in these cases no error is raised in urllib (issue
2819 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00002820

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00002827- Added a timeout parameter to the constructor of other protocols
2828 (telnetlib, ftplib, smtplib and poplib). This is second part of the
2829 work started with create_connection() and timeout in httplib, and
2830 closes patch #723312.
2831
Vinay Sajip8549ce32007-05-06 17:53:37 +00002832- Patch #1676823: Added create_connection() to socket.py, which may be
2833 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00002834 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00002835
Martin v. Löwis0af33882007-03-23 13:27:15 +00002836- Bug #978833: Revert r50844, as it broke _socketobject.dup.

2856
Georg Brandlf66b6032007-03-14 08:27:52 +00002857- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00002858 AttributeError instead of an IOError when the server's response
2859 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00002860
Georg Brandl3ee81df2008-05-17 18:14:43 +00002861- Patch #957650: "%var%" environment variable references are now
2862 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00002864
Georg Brandl3ee81df2008-05-17 18:14:43 +00002865- Patch #1429539: pdb now correctly initializes the __main__ module
2866 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00002867 correctly now.
2868
Georg Brandlbad6f192007-03-13 21:32:56 +00002869- The nonobvious commands.getstatus() function is now deprecated.

2875
Georg Brandl3ee81df2008-05-17 18:14:43 +00002876- Patch #1530482: add pydoc.render_doc() which returns the
2877 documentation for a thing instead of paging it to stdout, which
2878 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00002879
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Patch #1533909: the timeit module now accepts callables in addition

2887 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00002889- Patch #1581073: add a flag to textwrap that prevents the dropping of

2891
Georg Brandl92a6bae2007-03-13 17:43:32 +00002892- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002893 are set for invalid interpolation sequences that would lead to
2894 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00002895

Georg Brandl3ee81df2008-05-17 18:14:43 +00002910 field names in its exception message if you try to write a record
2911 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00002929

2937 returned string up to the first NUL character.
2938

2948
Georg Brandl3ee81df2008-05-17 18:14:43 +00002949- unittest now verifies more of its assumptions. In particular,
2950 TestCase and TestSuite subclasses (not instances) are no longer
2951 accepted in TestSuite.addTest(). This should cause no
2952 incompatibility since it never made sense with ordinary subclasses
2953 -- the failure just occurred later, with a more cumbersome
2954 exception.

2963 given a unicode argument and os.listdir() returns unicode filenames.
2964
Georg Brandl3ee81df2008-05-17 18:14:43 +00002965- Patch #1673619: setup.py identifies extension modules it doesn't

2967 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003343 time so that opening a database previously created with the DB_DUP
3344 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3345 opens. Specifically: dictionary assignment to a DB object will
3346 replace all values for a given key when the database allows
3347 duplicate values. DB users should use DB.put(k, v) when they want
3348 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003349

3355 characters with ASCII value less than 32. Also, it correctly quotes
3356 dots only if they occur on a single line, as opposed to the previous
3357 behavior of quoting dots if they are the second character of any
3358 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003359
