Mark Dickinsone02c9d22010-05-07 13:23:18 +000015- Issue #1533: fix inconsistency in range function argument
16 processing: any non-float non-integer argument is now converted to
17 an integer (if possible) using its __int__ method. Previously, only
18 small arguments were treated this way; larger arguments (those whose
19 __int__ was outside the range of a C long) would produce a TypeError.
20
Benjamin Petersonc218ce82010-04-16 22:43:53 +000021- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
22 passed to bytearray.

32 a fatal error in low memory condition.
33

Giampaolo Rodolà902b57b2010-05-06 18:24:02 +000042- Issue #8573: asyncore _strerror() function might throw ValueError.
43
44- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
45 error messages when accessing undefined class attributes because of the cheap
46 inheritance with the underlying socket object.

55 ASCII with backslashreplace error handler if str(value) failed
56
Mark Dickinson1cdfa5f2010-05-04 14:30:32 +000057- Issue #8567: Fix precedence of signals in Decimal module: when a
58 Decimal operation raises multiple signals and more than one of those
59 signals is trapped, the specification determines the order in which
60 the signals should be handled. In many cases this order wasn't
61 being followed, leading to the wrong Python exception being raised.

94 witnessed in test_httpservers.
95
Antoine Pitrouc689d962010-04-24 20:13:37 +000096- Issue #5103: SSL handshake would ignore the socket timeout and block
97 indefinitely if the other end didn't respond.
98
99- The do_handshake() method of SSL objects now adjusts the blocking mode of
100 the SSL structure if necessary (as other methods already do).
101
Antoine Pitroud4030da2010-04-23 23:35:01 +0000102- Issue #5238: Calling makefile() on an SSL object would prevent the

1022 kept open but the file object behaves like a closed file. The ``FileIO``
1023 object also got a new readonly attribute ``closefd``.
1024

1396What's New in Python 2.6.1
1397==========================
1398
1399*Release date: 04-Dec-2008*
1400
1401Core and Builtins
1402-----------------
1403
1404- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1405 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1406 instead of throwing a MemoryError.
1407
1408- Issue #4367: Python would segfault during compiling when the unicodedata
1409 module couldn't be imported and \N escapes were present.
1410
1411- Issue #4348: Some bytearray methods returned that didn't cause any change to
1412 the bytearray, returned the same bytearray instead of a copy.
1413
1414- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1415
1416- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1417
1418- Issue #4048: The parser module now correctly validates relative imports.
1419
1420- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1426- Issue #4209: Enabling unicode_literals and the print_function in the same
1427 __future__ import didn't work.
1428
1429- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1430 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1431 really executed because I cannot move to such directory on win2k)
1432
1433- Issue #4069: When set.remove(element) is used with a set element, the element
1434 is temporarily replaced with an equivalent frozenset. But the eventual
1435 KeyError would always report the empty frozenset([]) as the missing key. Now
1436 it correctly refers to the initial element.
1437
1438- Fixed C99 style comments in several files. Python is now C89 compatible
1439 again.

1589 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1590 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1591 ``printf`` function, whereas PyString_FromFormat has an independent
1592 implementation and uses "%zd" on all platforms for size_t values.
1593 This makes a difference on win64, where ``printf`` needs "%Id" to display
1594 64bit values.
1595
Benjamin Peterson97179b02008-09-09 20:55:01 +00001596- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1597 error.
1598
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001599- Issue #3777: long() applied to a float object now always return a long
1600 object; previously an int would be returned for small values. the __long__
1601 method is allowed to return either an int or a long, but the behaviour of
1602 float objects should not change to respect backward compatibility.
1603
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001604- Issue #3751: str.rpartition would perform a left-partition when called with
1605 a unicode argument.
1606
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001607- Issue #3683: Fix compilation when --without-threads is given.
1608
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001609- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001610 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001611 was correctly parsed but parsing of subsequent arguments failed.
1612
Vinay Sajip35e3b032008-09-01 14:33:59 +00001613- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001614 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1615 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1616 when given a tuple of classes as second argument, were looking up
1617 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1618 type object.
1619
Neal Norwitz18aa3882008-08-24 05:04:52 +00001620- Fix crashes on memory allocation failure found with failmalloc.

1636
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001637- Issue #1204: The configure script now tests for additional libraries
1638 that may be required when linking against readline. This fixes issues
1639 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1689 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1690 for catch_warnings() also led to an improvement in the raising of a
1691 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001754What's New in Python 2.6 beta 3?
1755================================
1756
Barry Warsaw07a4a382008-08-21 01:15:08 +00001757*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001758
1759Core and Builtins
1760-----------------
1761
Guido van Rossumf8402962008-08-20 15:01:50 +00001762- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1763 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1764 extensions do not automatically benefit from the class attribute
1765 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1766 to their tp_flags field if they care. This is a backwards
1767 compatibility feature; in 3.0, all types will use the cache by
1768 default.
1769
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001770- Keyword arguments can now follow starred arguments. (``f(a, *args,
1771 keyword=23)`` is now valid syntax.)
1772
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001773- ctypes function pointers that are COM methods have a boolean True
1774 value again.
1775
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001776- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1777 by denying s# to parse objects that have a releasebuffer procedure,
1778 and introducing s*.
1779
Georg Brandl1e13ea92008-08-11 09:07:59 +00001780- Issue #3537: Fix an assertion failure when an empty but presized dict
1781 object was stored in the freelist.
1782
Mark Dickinsonb6467572008-08-04 21:30:09 +00001783- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1784 ValueError consistently across platforms.
1785
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001786- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1787 (64bit Unix, for example), unichr() would truncate its argument and return
1788 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1789
Neal Norwitze7d8be82008-07-31 17:17:14 +00001790- Apply security patches from Apple.
1791
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001792- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1793 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1794
Antoine Pitrou92f82162008-07-25 22:22:08 +00001795- Issue #1819: function calls with several named parameters are now on
1796 average 35% faster (as measured by pybench).
1797
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001798- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1799 the python debugger steps into a class statement: the free variables (local
1800 variables defined in an outer scope) would be deleted from the outer scope.
1801
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001802- Issue #2620: Overflow checking when allocating or reallocating memory
1803 was not always being done properly in some python types and extension
1804 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1805 all been updated to perform better checks and places in the code that
1806 would previously leak memory on the error path when such an allocation
1807 failed have been fixed.

1810-------
1811
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001812- Issue #3612: Added some missing basic types in ctypes.wintypes.
1813
Benjamin Petersone977ad42008-08-20 01:42:01 +00001814- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1815 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1816
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001817- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1818 version reported by these tools does not necessarily follow the python
1819 version numbering scheme, so the module is less strict when parsing it.
1820
Nick Coghlanf70385a2008-08-18 12:42:46 +00001821- Issue #2235: Added Py3k warnings for types which will become unhashable
1822 under the stricter __hash__ inheritance rules in 3.0. Several types
1823 which did not meet the rules for hash invariants and were already
1824 unhashable in 3.0 have now been explicitly flagged as unhashable in
1825 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1826 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1827
Brett Cannon88f801d2008-08-18 00:46:22 +00001828- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1829 imported into the module but exposed as part of the module's API.
1830
Brett Cannon7b96f072008-08-18 00:41:11 +00001831- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1832
Brett Cannon46225e72008-08-18 00:36:52 +00001833- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1834
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001835- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1836
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001837- Issue #3575: Incremental decoder's decode function now takes bytearray
1838 by using 's*' instead of 't#'.
1839
Jesus Cea585ad8a2009-07-02 15:37:21 +00001840- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001841 fails unicode conversion on 2nd parameter. (windows only)
1842
Facundo Batista94f243a2008-08-17 03:38:39 +00001843- Issue 2464. urllib2 now supports a malformation in the URL received
1844 in a redirect.
1845
Brett Cannonabe423e2008-08-16 21:47:07 +00001846- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001847 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001848
Facundo Batistaeb90b782008-08-16 14:44:07 +00001849- Issue #2776: fixed small issue when handling an URL with double slash
1850 after a 302 response in the case of not going through a proxy.
1851
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001852- Issue #2676: in the email package, content-type parsing was hanging on
1853 pathological input because of quadratic or exponential behaviour of a
1854 regular expression.
1855
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001856- Issue #3476: binary buffered reading through the new "io" library is now
1857 thread-safe.
1858
Brett Cannonbf3157b2008-08-14 05:00:03 +00001859- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1860 since mimetools itself is deprecated. Because modules are cached, all
1861 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1862
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001863- Issue #3134: shutil referenced undefined WindowsError symbol.
1864
Robert Schuppenies14646332008-08-10 11:01:53 +00001865- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1866 menu entries were not deleted.
1867
Brett Cannon83e81842008-08-09 23:30:55 +00001868- Copied the implementation of reduce() to _functools.reduce() to have a
1869 version that did not raise a DeprecationWarning under -3.
1870
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001871- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1872 a MemoryError rather than silently stop the iteration.
1873
Guido van Rossum59ce9012008-08-09 14:55:34 +00001874- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1875 to _sre.compile() will now be rejected. This should not affect anybody

Antoine Pitroude781a42008-08-09 12:43:23 +00001897 asking for a specific length. This problem only affected files opened

1954-----------------
1955
Georg Brandl3e483f62008-07-16 22:57:41 +00001956- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1957 its methods now allow for items objects that can be converted to
1958 an integer using operator.index().
1959
Mark Dickinson64b7e502008-07-16 09:40:03 +00001960- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1961 produced a ValueError instead of giving the correct float.
1962
Eric Smitha5fa5a22008-07-16 00:11:49 +00001963- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1964 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1965
Mark Dickinson7103aa42008-07-15 19:08:33 +00001966- Issue #3008: the float type has a new instance method 'float.hex'
1967 and a new class method 'float.fromhex' to convert floating-point
1968 numbers to and from hexadecimal strings, respectively.
1969
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001970- Issue #2235: __hash__ is once again inherited by default. To allow
1971 collections.Hashable to remain meaningful in the presence of the
1972 default hash implementation (object.__hash__), it is now possible
1973 to explicit block inheritance of hash by setting __hash__=None at
1974 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1975 level.
1976
Nick Coghlanb028f502008-07-13 14:52:36 +00001977- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1978 the parent module cannot be found while performing an absolute import.
1979 This means that an incorrectly defined __package__ attribute will
1980 now only prevent relative imports in that module rather than causing
1981 all imports from that module to fail.
1982
Nick Coghlan14ff9942008-07-08 14:21:42 +00001983- Issue #2517: Allow unicode messages in Exceptions again by correctly

1993 another thread's dictionary.
1994
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001995- Issue #3004: Minor change to slice.indices(): the start and stop
1996 arguments are now treated identically, making the behaviour easier
1997 to describe and understand. For example, slice(None, -10,
1998 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1999 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2000 10, -1).
2001
Georg Brandl278fc502008-07-19 12:46:12 +00002002- Issue #3219: Calling a function with repeated keyword arguments,
2003 f(a=2, a=23), would not cause a syntax error. This was a regression
2004 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002042- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2043 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002044 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002045 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002061- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2449
Brett Cannonb61d8012008-05-11 23:39:04 +00002450- ``Lib/lib-old`` is now added to sys.path.
2451
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002452- On MacOS X it is now possible to install the framework in 64-bit
2453 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002454 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002455
2456 This is controlled by the configure argument ``--with-universal-archs``:
2457
2458 - ``--with-universal-archs=all``: install 4-way universal
2459
2460 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2461
2462 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2463
2464 This option should be used in combination with ``--enable-universalsdk=``.
2465
2466 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2474- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002475
2476- The PyString functions have been renamed to PyBytes. A batch of
2477 defines were added so that the linker still sees the original
2478 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002516- Issue #1631171: Re-implement the 'warnings' module in C (the
2517 original Python code has been kept as backup). This will allow for
2518 using the 'warning's machinery in such places as the parser where
2519 use of pure Python code is not possible. Both the ``showarning()``
2520 and ``formatwarning()`` gain an optional 'line' argument which is
2521 not called by default for backwards-compatibility reasons. Setting
2522 ``warnings.showwarning()`` to an implementation that lacks support
2523 for the ``line`` argument will raise a DeprecationWarning.

2547
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002548- The getpass module has been improved on Unix. It now uses /dev/tty
2549 by default and uses stderr instead of stdout. A GetPassWarning is
2550 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002565- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002566 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002586- Issue #2550: The approach used by client/server code for obtaining
2587 ports to listen on in network-oriented tests has been refined in an
2588 effort to facilitate running multiple instances of the entire
2589 regression test suite in parallel without issue.
2590 test_support.bind_port() has been fixed such that it will always
2591 return a unique port -- which wasn't always the case with the
2592 previous implementation, especially if socket options had been set
2593 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2594 new implementation of bind_port() will actually raise an exception
2595 if it is passed an AF_INET/SOCK_STREAM socket with either the
2596 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2597 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2598 the socket it's been passed. This currently only applies to
2599 Windows. This option prevents any other sockets from binding to the
2600 host/port we've bound to, thus removing the possibility of the
2601 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2602 when a second SOCK_STREAM socket binds and accepts to a host/port
2603 that's already been bound by another socket. The optional preferred
2604 port parameter to bind_port() has been removed. Under no
2605 circumstances should tests be hard coding ports!
2606
2607 test_support.find_unused_port() has also been introduced, which will
2608 pass a temporary socket object to bind_port() in order to obtain an
2609 unused port. The temporary socket object is then closed and
2610 deleted, and the port is returned. This method should only be used
2611 for obtaining an unused port in order to pass to an external program
2612 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2613 a parameter to a server-oriented class that doesn't give you direct
2614 access to the underlying socket used.
2615
2616 Finally, test_support.HOST has been introduced, which should be used
2617 for the host argument of any relevant socket calls (i.e. bind and
2618 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002619
2620 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002621 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002622 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2623 test_asynchat and test_socket_ssl.
2624
Georg Brandl3ee81df2008-05-17 18:14:43 +00002625 It is now possible for multiple instances of the regression test
2626 suite to run in parallel without issue.

2893-----------------
2894
Fred Drakea8ee94b2008-03-01 02:45:07 +00002895- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002896 644. The mode is now inherited from the py file.

2899
2900- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002901
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002902- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002903 issue 215555 for a discussion.
2904
Eric Smitha73fbe72008-02-23 03:09:44 +00002905- Added the future_builtins module, which contains hex() and oct().
2906 These are the PEP 3127 version of these functions, designed to be
2907 compatible with the hex() and oct() builtins from Python 3.0. They
2908 differ slightly in their output formats from the existing, unchanged
2909 Python 2.6 builtins. The expected usage of the future_builtins
2910 module is:
2911 from future_builtins import hex, oct
2912
Eric Smith7ef40bf2008-02-20 23:34:22 +00002913- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2914 exponents for exponents with absolute value < 100. Follows C99
2915 standard. This is a change on Windows, which would use 3 digits.
2916 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2917 so that any alterations it does to the resulting string will be
2918 available in stringlib/formatter.h (for float.__format__).
2919
Eric Smith5a3c1352008-02-19 13:21:56 +00002920- Implemented PEP 3101, Advanced String Formatting. This adds a new
2921 builtin format(); a format() method for str and unicode; a
2922 __format__() method to object, str, unicode, int, long, float, and
2923 datetime; the class string.Formatter; and the C API
2924 PyObject_Format().
2925
Georg Brandl3ee81df2008-05-17 18:14:43 +00002926- Fixed several potential crashes, all caused by specially crafted
2927 __del__ methods exploiting objects in temporarily inconsistent
2928 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002929
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002930- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002931 prevent a possible crash: an Abstract Base Class would try to access
2932 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002933

Georg Brandl3ee81df2008-05-17 18:14:43 +00002937- Clear all free lists during a gc.collect() of the highest generation
2938 in order to allow pymalloc to free more arenas. Python may give back
2939 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002940
Georg Brandl3ee81df2008-05-17 18:14:43 +00002941- Issue #2045: Fix an infinite recursion triggered when printing a
2942 subclass of collections.defaultdict, if its default_factory is set
2943 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002944
Christian Heimesf75dbef2008-02-08 00:11:31 +00002945- Fixed a minor memory leak in dictobject.c. The content of the free
2946 list was not freed on interpreter shutdown.
2947
Georg Brandl5a7eca12010-03-21 19:29:04 +00002948- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002949 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002950
Georg Brandl3ee81df2008-05-17 18:14:43 +00002951- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2952 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002953 to compact the internal free lists of pre-allocted ints and floats.
2954
Georg Brandl3ee81df2008-05-17 18:14:43 +00002955- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2956 calls. Python expected the return type int but the fork familie
2957 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002958

Christian Heimes4d4f2702008-01-30 11:32:37 +00002967
Georg Brandl3ee81df2008-05-17 18:14:43 +00002968- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2969 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002970
Georg Brandl3ee81df2008-05-17 18:14:43 +00002971- Patch #1473257: generator objects gain a gi_code attribute. This is
2972 the same object as the func_code attribute of the function that
2973 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002974
Georg Brandl3ee81df2008-05-17 18:14:43 +00002975- Issue #1920: "while 0" statements were completely removed by the
2976 compiler, even in the presence of an "else" clause, which is
2977 supposed to be run when the condition is false. Now the compiler
2978 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002979
Guido van Rossumeead05f2008-01-24 18:21:02 +00002980- A few crashers fixed: weakref_in_del.py (issue #1377858);
2981 loosing_dict_ref.py (issue #1303614, test67.py);
2982 borrowed_ref_[34].py (not in tracker).
2983
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002984- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002985 suppressed while an extension is loaded by calling SetErrorMode in
2986 dynload_win.c. The error is still reported properly.
2987
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002989 several extension methods and modules do not work without unicode
2990 support.
2991
Georg Brandl26543b12008-01-21 18:36:51 +00002992- Issue #1882: when compiling code from a string, encoding cookies in the
2993 second line of code were not always recognized correctly.
2994
Georg Brandl14404b62008-01-19 19:27:05 +00002995- Issue #1679: "0x" was taken as a valid integer literal.
2996
Georg Brandl6caad7d2008-01-26 14:19:22 +00002997- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002998 added.
2999
Christian Heimesc94e2b52008-01-14 04:13:37 +00003000- sys.float_info / PyFloat_GetInfo: The floating point information
3001 object was converted from a dict to a specialized structseq object.
3002
Georg Brandl3ee81df2008-05-17 18:14:43 +00003003- Patch #1816: Added sys.flags structseq. It exposes the status of
3004 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003005
Georg Brandl3ee81df2008-05-17 18:14:43 +00003006- Objects/structseq.c: Implemented new structseq representation. The
3007 patch makes structseqs (e.g. the return value of os.stat) more
3008 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003009
Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Patch #1700288: added a type attribute cache that caches method
3011 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003012
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003013- Bug #1776: __import__() no longer accepts filenames on any platform.
3014 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003015
Georg Brandlaed6c662008-01-07 17:25:53 +00003016- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3017
Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3019 envvar and sys.dont_write_bytecode attribute. All these can be set
3020 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003021
Georg Brandl3ee81df2008-05-17 18:14:43 +00003022- Improve some exception messages when Windows fails to load an
3023 extension module. Now we get for example '%1 is not a valid Win32
3024 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003025
Georg Brandl3ee81df2008-05-17 18:14:43 +00003026- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00003027
Georg Brandl3ee81df2008-05-17 18:14:43 +00003028- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3029 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003030
Christian Heimes0a8143f2007-12-18 23:22:54 +00003031- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003032 and INF. float("nan"), float("inf") and float("-inf") now work on
3033 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003034
Georg Brandl3ee81df2008-05-17 18:14:43 +00003035- Compiler now generates simpler and faster code for dictionary
3036 literals. The oparg for BUILD_MAP now indicates an estimated
3037 dictionary size. There is a new opcode, STORE_MAP, for adding
3038 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003039
Georg Brandl3ee81df2008-05-17 18:14:43 +00003040- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00003041
Georg Brandl3ee81df2008-05-17 18:14:43 +00003042- Issue #1620: New property decorator syntax was modifying the
3043 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003044
Georg Brandl3ee81df2008-05-17 18:14:43 +00003045- Issue #1538: Avoid copying string in split/rsplit if the split char
3046 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003047
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003048- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003049 SystemError.
3050
Nick Coghlanef01d822007-12-03 12:55:17 +00003051- PEP 366: Allow explicit relative imports when executing modules
3052 inside packages with the -m switch via a new module level
3053 __package__ attribute.
3054
Georg Brandl3ee81df2008-05-17 18:14:43 +00003055- Issue #1402: Fix a crash on exit, when another thread is still
3056 running, and if the deallocation of its frames somehow calls the
3057 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003058

3060
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00003061- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003062 attribute of an empty cell object.
3063
Georg Brandl3ee81df2008-05-17 18:14:43 +00003064- Issue #1460: The utf-7 incremental decoder did not accept truncated
3065 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003066
Georg Brandl3ee81df2008-05-17 18:14:43 +00003067- Patch #1739468: Directories and zipfiles containing a __main__.py
3068 file can now be directly executed by passing their name to the
3069 interpreter. The directory/zipfile is automatically inserted as the
3070 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003071
Georg Brandl3ee81df2008-05-17 18:14:43 +00003072- Issue #1265: Fix a problem with sys.settrace, if the tracing
3073 function uses a generator expression when at the same time the
3074 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003075
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003076- sets and frozensets now have an isdisjoint() method.
3077
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003078- optimize the performance of builtin.sum().
3079
Neal Norwitz44f326e2007-10-05 05:29:17 +00003080- Fix warnings found by the new version of the Coverity checker.
3081
Georg Brandl5a7eca12010-03-21 19:29:04 +00003082- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003083 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3084 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003085
Georg Brandl3ee81df2008-05-17 18:14:43 +00003086- Issue #1686386: Tuple's tp_repr did not take into account the
3087 possibility of having a self-referential tuple, which is possible
3088 from C code. Nor did object's tp_str consider that a type's tp_str
3089 could do something that could lead to an inifinite recursion.
3090 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3091 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003092
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093- Issue #1164: It was possible to trigger deadlock when using the
3094 'print' statement to write to a file since the GIL was not released
3095 as needed. Now PyObject_Print() does the right thing along with
3096 various tp_print implementations of the built-in types and those in
3097 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003098
Georg Brandl3ee81df2008-05-17 18:14:43 +00003099- Issue #1147: Exceptions were directly allowing string exceptions in
3100 their throw() method even though string exceptions no longer
3101 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003102
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- Issue #1096: Prevent a segfault from getting the repr of a very
3104 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003105
Brett Cannon1e534b52007-09-07 04:18:30 +00003106- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107 PyObject_Call() never calling back out to Python code to trigger
3108 recursion depth updates/checks. Required the creation of a static
3109 RuntimeError instance in case normalizing an exception put the
3110 recursion check value past its limit. Fixes crashers
3111 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003112
Georg Brandl3ee81df2008-05-17 18:14:43 +00003113- Patch #1031213: Decode source line in SyntaxErrors back to its
3114 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00003116- Patch #1673759: add a missing overflow check when formatting floats
3117 with %G.
3118
Georg Brandl3ee81df2008-05-17 18:14:43 +00003119- Prevent expandtabs() on string and unicode objects from causing a
3120 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00003121

Georg Brandla5ea6892007-06-01 11:33:33 +00003125
Neal Norwitz0ac60192007-05-27 04:08:54 +00003126- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003127 __*__ attributes. (Some already existed, e.g., __doc__ and
3128 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003129
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003130- Add -3 option to the interpreter to warn about features that are
3131 deprecated and will be changed/removed in Python 3.0.
3132
Georg Brandl2134e752007-05-21 20:34:16 +00003133- Patch #1686487: you can now pass any mapping after '**' in function
3134 calls.
3135
Collin Winter62903052007-05-18 23:11:24 +00003136- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137 "except E as target:". This is to provide forwards compatibility
3138 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003139
Brett Cannon229cee22007-05-05 01:34:02 +00003140- Deprecate BaseException.message as per PEP 352.
3141
Georg Brandl3ee81df2008-05-17 18:14:43 +00003142- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003143 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003144
Vinay Sajip8549ce32007-05-06 17:53:37 +00003145- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003146 setting a plain string, ie don't expand to single letter identifiers.
3147
Raymond Hettinger13936692007-04-11 18:40:58 +00003148- Request #1191699: Slices can now be pickled.
3149
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003150- Request #1193128: str.translate() now allows a None argument for
3151 translations that only remove characters without re-mapping the
3152 remaining characters.
3153
Georg Brandl5cb76c12007-03-21 09:00:39 +00003154- Patch #1682205: a TypeError while unpacking an iterable is no longer
3155 masked by a generic one with the message "unpack non-sequence".
3156
Neal Norwitzaa754b72007-03-21 06:39:48 +00003157- Remove unused file Python/fmod.c.
3158
Guido van Rossum143b5642007-03-23 04:58:42 +00003159- Bug #1683368: The object.__init__() and object.__new__() methods are
3160 now stricter in rejecting excess arguments. The only time when
3161 either allows excess arguments is when it is not overridden and the
3162 other one is. For backwards compatibility, when both are
3163 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003164 warning later). Also, type.__init__() insists on the same signature
3165 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003166
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3168 object to complex using its __complex__() method before falling back
3169 to the __float__() method. Therefore, the functions in the cmath
3170 module now can operate on objects that define a __complex__()
3171 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003172
Georg Brandl3ee81df2008-05-17 18:14:43 +00003173- Patch #1623563: allow __class__ assignment for classes with
3174 __slots__. The old and the new class are still required to have the
3175 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003176
Georg Brandl3ee81df2008-05-17 18:14:43 +00003177- Patch #1642547: Fix an error/crash when encountering syntax errors
3178 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003180- Patch #1462488: Python no longer segfaults when
3181 ``object.__reduce_ex__()`` is called with an object that is faking
3182 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003183
Georg Brandl3ee81df2008-05-17 18:14:43 +00003184- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003187- Patch #1444529: the builtin compile() now accepts keyword arguments.
3188
Georg Brandl7b9c5552007-03-12 14:30:05 +00003189- Bug #1678647: write a newline after printing an exception in any
3190 case, even when converting the value to a string failed.
3191
Georg Brandl871f1bc2007-03-12 13:17:36 +00003192- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003193 its argument, if it exists. If not, it will work like before. This
3194 allows customizing the output of dir() in the presence of a
3195 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003196
Collin Winter276887b2007-03-12 16:11:39 +00003197- Patch #922167: Python no longer segfaults when faced with infinitely
3198 self-recursive reload() calls (as reported by bug #742342).
3199
Georg Brandl3ee81df2008-05-17 18:14:43 +00003200- Patch #1675981: remove unreachable code from ``type.__new__()``
3201 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00003202
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203- Patch #1491866: change the complex() constructor to allow
3204 parthensized forms. This means complex(repr(x)) now works instead of

3716 ".cpp" too.
3717
Facundo Batistad918a652007-04-24 13:54:38 +00003718- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003719 the client's request was successfully received, understood, and
3720 accepted. Now in these cases no error is raised in urllib (issue
3721 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003722

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003729- Added a timeout parameter to the constructor of other protocols
3730 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3731 work started with create_connection() and timeout in httplib, and
3732 closes patch #723312.
3733
Vinay Sajip8549ce32007-05-06 17:53:37 +00003734- Patch #1676823: Added create_connection() to socket.py, which may be
3735 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003736 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003737
Martin v. Löwis0af33882007-03-23 13:27:15 +00003738- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003745- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
3746 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00003747 directories.
3748

3750 GNOME or KDE browser, depending on whether there is a session of one

3758
Georg Brandlf66b6032007-03-14 08:27:52 +00003759- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003760 AttributeError instead of an IOError when the server's response
3761 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003762
Georg Brandl3ee81df2008-05-17 18:14:43 +00003763- Patch #957650: "%var%" environment variable references are now
3764 properly expanded in ntpath.expandvars(), also "~user" home
3765 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00003766
Georg Brandl3ee81df2008-05-17 18:14:43 +00003767- Patch #1429539: pdb now correctly initializes the __main__ module
3768 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003769 correctly now.
3770
Georg Brandlbad6f192007-03-13 21:32:56 +00003771- The nonobvious commands.getstatus() function is now deprecated.

3777
Georg Brandl3ee81df2008-05-17 18:14:43 +00003778- Patch #1530482: add pydoc.render_doc() which returns the
3779 documentation for a thing instead of paging it to stdout, which
3780 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003781
Georg Brandl3ee81df2008-05-17 18:14:43 +00003782- Patch #1533909: the timeit module now accepts callables in addition

3788 parameter which can be set to False to prevent the default
3789 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003790
Georg Brandl9e6b4702007-03-13 18:15:41 +00003791- Patch #1581073: add a flag to textwrap that prevents the dropping of
3792 whitespace while wrapping.
3793
Georg Brandl92a6bae2007-03-13 17:43:32 +00003794- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003795 are set for invalid interpolation sequences that would lead to
3796 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003797

3810
Georg Brandl94fe3f52007-03-13 09:32:11 +00003811- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812 field names in its exception message if you try to write a record
3813 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003831

3839 returned string up to the first NUL character.
3840

3850
Georg Brandl3ee81df2008-05-17 18:14:43 +00003851- unittest now verifies more of its assumptions. In particular,
3852 TestCase and TestSuite subclasses (not instances) are no longer
3853 accepted in TestSuite.addTest(). This should cause no
3854 incompatibility since it never made sense with ordinary subclasses
3855 -- the failure just occurred later, with a more cumbersome
3856 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003857

3865 given a unicode argument and os.listdir() returns unicode filenames.
3866
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867- Patch #1673619: setup.py identifies extension modules it doesn't

3869 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004245 time so that opening a database previously created with the DB_DUP
4246 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4247 opens. Specifically: dictionary assignment to a DB object will
4248 replace all values for a given key when the database allows
4249 duplicate values. DB users should use DB.put(k, v) when they want
4250 to store duplicates; not DB[k] = v.

4257 characters with ASCII value less than 32. Also, it correctly quotes
4258 dots only if they occur on a single line, as opposed to the previous
4259 behavior of quoting dots if they are the second character of any
4260 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004261
