Victor Stinner082a65a2010-07-28 01:55:43 +000015- Issue #6213: Implement getstate() and setstate() methods of utf-8-sig and
16 utf-16 incremental encoders.
17
Ezio Melotti86e5e172010-07-03 05:34:39 +000018- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
19 start byte and the continuation byte(s) are now considered invalid, instead
20 of the number of bytes specified by the start byte.
21 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
22 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
23 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
24 Previous versions returned a single u'\ufffd'.
25
Benjamin Peterson8d649632010-06-22 19:21:33 +000026- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.

30 (higher than 0x10000).
31

Mark Dickinsonb671c292010-06-05 12:15:35 +000033 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
34 arises from the "Overriding __eq__ blocks inheritance ..." warning
35 when turned into an exception: in this case the exception simply
36 gets ignored.
Mark Dickinson80068da2010-06-05 11:59:41 +000037
Georg Brandl0ba1f012010-08-01 22:00:39 +000038- Issue #4108: In urllib.robotparser, if there are multiple 'User-agent: *'
39 entries, consider the first one.
40
Georg Brandl86edb142010-08-01 21:58:18 +000041- Issue #9354: Provide getsockopt() in asyncore's file_wrapper.

47 and error handler, instead of writing to the C stderr file in utf-8
48
Brett Cannon7d006262010-05-20 18:41:08 +000049- Issue #7902: When using explicit relative import syntax, don't try

53 it from another thread. Patch by Daniel Stutzbach.
54
Mark Dickinsone02c9d22010-05-07 13:23:18 +000055- Issue #1533: fix inconsistency in range function argument
56 processing: any non-float non-integer argument is now converted to
57 an integer (if possible) using its __int__ method. Previously, only
58 small arguments were treated this way; larger arguments (those whose
59 __int__ was outside the range of a C long) would produce a TypeError.
60
Barry Warsaw60537442010-08-03 22:39:42 +000061- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize

71- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
Victor Stinner4fd2ff92010-03-22 12:56:39 +000072
Victor Stinnerd156fa32010-03-21 13:32:31 +000073- Issue #7544: Preallocate thread memory before creating the thread to avoid
74 a fatal error in low memory condition.
75

87 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

Georg Brandl21896072010-08-01 22:31:28 +00001235- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettinger24e28722009-02-02 22:44:06 +00001236 were suppressing all exceptions. These include list(), filter(), map(),

1238
Antoine Pitroua1b22ce2009-01-13 23:25:47 +00001239- Issue #4935: The overflow checking code in the expandtabs() method common
1240 to str, bytes and bytearray could be optimized away by the compiler, letting
1241 the interpreter segfault instead of raising an error.

1246 an existing .py counterpart, override the co_filename attributes of all
1247 code objects if the original filename is obsolete (which can happen if the

Vinay Sajip6badbe92009-01-20 22:49:13 +00001286- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +00001287 method on file objects with closefd=False. The file descriptor is still
1288 kept open but the file object behaves like a closed file. The ``FileIO``
1289 object also got a new readonly attribute ``closefd``.
1290
Georg Brandlfa71a902008-12-05 09:08:28 +00001291- Issue #3689: The list reversed iterator now supports __length_hint__

Antoine Pitrou19fec8b2009-01-21 00:56:37 +00001463- Issue #5008: When a file is opened in append mode with the new IO library,
1464 do an explicit seek to the end of file (so that e.g. tell() returns the

1466 traditional 2.x file object.

1495
1496- Issue #4201: pdb can now access and display source code loaded via
1497 zipimport (or any other conformant PEP 302 loader). Original patch by
1498 Alexander Belopolsky.
1499
1500- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1501 302 conformant loader) will now work correctly in most cases (they
1502 are still subject to the constraints that exist for all code running

1662What's New in Python 2.6.1
1663==========================
1664
1665*Release date: 04-Dec-2008*
1666
1667Core and Builtins
1668-----------------
1669
1670- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1671 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1672 instead of throwing a MemoryError.
1673
1674- Issue #4367: Python would segfault during compiling when the unicodedata
1675 module couldn't be imported and \N escapes were present.
1676
1677- Issue #4348: Some bytearray methods returned that didn't cause any change to
1678 the bytearray, returned the same bytearray instead of a copy.
1679
1680- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1681
1682- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1683
1684- Issue #4048: The parser module now correctly validates relative imports.
1685
1686- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1690 method does not return iterators for the 4th and 5th items.
1691
1692- Issue #4209: Enabling unicode_literals and the print_function in the same
1693 __future__ import didn't work.
1694
1695- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1696 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1697 really executed because I cannot move to such directory on win2k)
1698
1699- Issue #4069: When set.remove(element) is used with a set element, the element
1700 is temporarily replaced with an equivalent frozenset. But the eventual
1701 KeyError would always report the empty frozenset([]) as the missing key. Now
1702 it correctly refers to the initial element.
1703
1704- Fixed C99 style comments in several files. Python is now C89 compatible
1705 again.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001854- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1855 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1856 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1857 ``printf`` function, whereas PyString_FromFormat has an independent
1858 implementation and uses "%zd" on all platforms for size_t values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001862- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1863 error.
1864
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001865- Issue #3777: long() applied to a float object now always return a long
1866 object; previously an int would be returned for small values. the __long__
1867 method is allowed to return either an int or a long, but the behaviour of
1868 float objects should not change to respect backward compatibility.
1869
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001870- Issue #3751: str.rpartition would perform a left-partition when called with
1871 a unicode argument.
1872
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001873- Issue #3683: Fix compilation when --without-threads is given.
1874
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001875- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001876 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001877 was correctly parsed but parsing of subsequent arguments failed.
1878
Vinay Sajip35e3b032008-09-01 14:33:59 +00001879- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001880 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1881 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1882 when given a tuple of classes as second argument, were looking up
1883 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1884 type object.
1885
Neal Norwitz18aa3882008-08-24 05:04:52 +00001886- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00001955 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1956 for catch_warnings() also led to an improvement in the raising of a

1981 without limit.
1982
Benjamin Peterson37346b22008-08-23 20:27:43 +00001983- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002020What's New in Python 2.6 beta 3?
2021================================
2022
Barry Warsaw07a4a382008-08-21 01:15:08 +00002023*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002024
2025Core and Builtins
2026-----------------
2027
Guido van Rossumf8402962008-08-20 15:01:50 +00002028- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2029 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2030 extensions do not automatically benefit from the class attribute
2031 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2032 to their tp_flags field if they care. This is a backwards
2033 compatibility feature; in 3.0, all types will use the cache by
2034 default.
2035
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002036- Keyword arguments can now follow starred arguments. (``f(a, *args,
2037 keyword=23)`` is now valid syntax.)
2038
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002039- ctypes function pointers that are COM methods have a boolean True
2040 value again.
2041
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002042- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2043 by denying s# to parse objects that have a releasebuffer procedure,
2044 and introducing s*.
2045
Georg Brandl1e13ea92008-08-11 09:07:59 +00002046- Issue #3537: Fix an assertion failure when an empty but presized dict
2047 object was stored in the freelist.
2048
Mark Dickinsonb6467572008-08-04 21:30:09 +00002049- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2050 ValueError consistently across platforms.
2051
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002052- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2053 (64bit Unix, for example), unichr() would truncate its argument and return
2054 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2055
Neal Norwitze7d8be82008-07-31 17:17:14 +00002056- Apply security patches from Apple.
2057
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002058- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2059 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2060
Antoine Pitrou92f82162008-07-25 22:22:08 +00002061- Issue #1819: function calls with several named parameters are now on
2062 average 35% faster (as measured by pybench).
2063
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002064- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2065 the python debugger steps into a class statement: the free variables (local
2066 variables defined in an outer scope) would be deleted from the outer scope.
2067
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002068- Issue #2620: Overflow checking when allocating or reallocating memory
2069 was not always being done properly in some python types and extension
2070 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2071 all been updated to perform better checks and places in the code that
2072 would previously leak memory on the error path when such an allocation
2073 failed have been fixed.

2077
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002078- Issue #3612: Added some missing basic types in ctypes.wintypes.
2079
Benjamin Petersone977ad42008-08-20 01:42:01 +00002080- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2081 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2082
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002083- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2084 version reported by these tools does not necessarily follow the python
2085 version numbering scheme, so the module is less strict when parsing it.
2086
Nick Coghlanf70385a2008-08-18 12:42:46 +00002087- Issue #2235: Added Py3k warnings for types which will become unhashable
2088 under the stricter __hash__ inheritance rules in 3.0. Several types
2089 which did not meet the rules for hash invariants and were already
2090 unhashable in 3.0 have now been explicitly flagged as unhashable in
2091 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2092 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2093
Brett Cannon88f801d2008-08-18 00:46:22 +00002094- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2095 imported into the module but exposed as part of the module's API.
2096
Brett Cannon7b96f072008-08-18 00:41:11 +00002097- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2098
Brett Cannon46225e72008-08-18 00:36:52 +00002099- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002101- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2102
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002103- Issue #3575: Incremental decoder's decode function now takes bytearray
2104 by using 's*' instead of 't#'.
2105
Jesus Cea585ad8a2009-07-02 15:37:21 +00002106- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002107 fails unicode conversion on 2nd parameter. (windows only)
2108
Georg Brandl21896072010-08-01 22:31:28 +00002109- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00002110 in a redirect.
2111
Brett Cannonabe423e2008-08-16 21:47:07 +00002112- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002113 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002114
Facundo Batistaeb90b782008-08-16 14:44:07 +00002115- Issue #2776: fixed small issue when handling an URL with double slash
2116 after a 302 response in the case of not going through a proxy.
2117
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002118- Issue #2676: in the email package, content-type parsing was hanging on
2119 pathological input because of quadratic or exponential behaviour of a
2120 regular expression.
2121
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002122- Issue #3476: binary buffered reading through the new "io" library is now
2123 thread-safe.
2124
Brett Cannonbf3157b2008-08-14 05:00:03 +00002125- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2126 since mimetools itself is deprecated. Because modules are cached, all
2127 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2128
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002129- Issue #3134: shutil referenced undefined WindowsError symbol.
2130
Robert Schuppenies14646332008-08-10 11:01:53 +00002131- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2132 menu entries were not deleted.
2133
Brett Cannon83e81842008-08-09 23:30:55 +00002134- Copied the implementation of reduce() to _functools.reduce() to have a
2135 version that did not raise a DeprecationWarning under -3.
2136
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002137- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2138 a MemoryError rather than silently stop the iteration.
2139
Guido van Rossum59ce9012008-08-09 14:55:34 +00002140- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2141 to _sre.compile() will now be rejected. This should not affect anybody
2142 since the re.compile() function never generates invalid re-bytecode.
2143
Skip Montanaroa032bf42008-08-08 22:52:51 +00002144- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2145 upon first access it can be automatically initialized from the csv file if

Antoine Pitroude781a42008-08-09 12:43:23 +00002163 asking for a specific length. This problem only affected files opened

2220-----------------
2221
Georg Brandl3e483f62008-07-16 22:57:41 +00002222- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2223 its methods now allow for items objects that can be converted to
2224 an integer using operator.index().
2225
Mark Dickinson64b7e502008-07-16 09:40:03 +00002226- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2227 produced a ValueError instead of giving the correct float.
2228
Eric Smitha5fa5a22008-07-16 00:11:49 +00002229- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2230 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2231
Mark Dickinson7103aa42008-07-15 19:08:33 +00002232- Issue #3008: the float type has a new instance method 'float.hex'
2233 and a new class method 'float.fromhex' to convert floating-point
2234 numbers to and from hexadecimal strings, respectively.
2235
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002236- Issue #2235: __hash__ is once again inherited by default. To allow
2237 collections.Hashable to remain meaningful in the presence of the
2238 default hash implementation (object.__hash__), it is now possible
2239 to explicit block inheritance of hash by setting __hash__=None at
2240 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2241 level.
2242
Nick Coghlanb028f502008-07-13 14:52:36 +00002243- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2244 the parent module cannot be found while performing an absolute import.
2245 This means that an incorrectly defined __package__ attribute will
2246 now only prevent relative imports in that module rather than causing
2247 all imports from that module to fail.
2248
Nick Coghlan14ff9942008-07-08 14:21:42 +00002249- Issue #2517: Allow unicode messages in Exceptions again by correctly

2259 another thread's dictionary.
2260
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002261- Issue #3004: Minor change to slice.indices(): the start and stop
2262 arguments are now treated identically, making the behaviour easier
2263 to describe and understand. For example, slice(None, -10,
2264 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2265 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2266 10, -1).
2267
Georg Brandl278fc502008-07-19 12:46:12 +00002268- Issue #3219: Calling a function with repeated keyword arguments,
2269 f(a=2, a=23), would not cause a syntax error. This was a regression
2270 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002272- Issue #2862: Make int and float freelist management consistent with
2273 other freelists. Changes their CompactFreeList apis into

2281 error when they failed.
2282
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002283- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002308- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2309 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002310 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002311 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002327- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2715
Brett Cannonb61d8012008-05-11 23:39:04 +00002716- ``Lib/lib-old`` is now added to sys.path.
2717
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002718- On MacOS X it is now possible to install the framework in 64-bit
2719 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002720 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002721
2722 This is controlled by the configure argument ``--with-universal-archs``:
2723
2724 - ``--with-universal-archs=all``: install 4-way universal
2725
2726 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2727
2728 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2729
2730 This option should be used in combination with ``--enable-universalsdk=``.
2731
2732 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00002741
2742- The PyString functions have been renamed to PyBytes. A batch of
2743 defines were added so that the linker still sees the original
2744 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002782- Issue #1631171: Re-implement the 'warnings' module in C (the
2783 original Python code has been kept as backup). This will allow for
2784 using the 'warning's machinery in such places as the parser where
2785 use of pure Python code is not possible. Both the ``showarning()``
2786 and ``formatwarning()`` gain an optional 'line' argument which is
2787 not called by default for backwards-compatibility reasons. Setting
2788 ``warnings.showwarning()`` to an implementation that lacks support
2789 for the ``line`` argument will raise a DeprecationWarning.

2813
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002814- The getpass module has been improved on Unix. It now uses /dev/tty
2815 by default and uses stderr instead of stdout. A GetPassWarning is
2816 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002831- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002832 extension modules between 32 and 64 bit platforms. See the distutls

2845 so the controlled environment will more closely mirror the typical
2846 script environment. This supports setup.py scripts that refer to
2847 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002852- Issue #2550: The approach used by client/server code for obtaining
2853 ports to listen on in network-oriented tests has been refined in an
2854 effort to facilitate running multiple instances of the entire
2855 regression test suite in parallel without issue.
2856 test_support.bind_port() has been fixed such that it will always
2857 return a unique port -- which wasn't always the case with the
2858 previous implementation, especially if socket options had been set
2859 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2860 new implementation of bind_port() will actually raise an exception
2861 if it is passed an AF_INET/SOCK_STREAM socket with either the
2862 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2863 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2864 the socket it's been passed. This currently only applies to
2865 Windows. This option prevents any other sockets from binding to the
2866 host/port we've bound to, thus removing the possibility of the
2867 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2868 when a second SOCK_STREAM socket binds and accepts to a host/port
2869 that's already been bound by another socket. The optional preferred
2870 port parameter to bind_port() has been removed. Under no
2871 circumstances should tests be hard coding ports!
2872
2873 test_support.find_unused_port() has also been introduced, which will
2874 pass a temporary socket object to bind_port() in order to obtain an
2875 unused port. The temporary socket object is then closed and
2876 deleted, and the port is returned. This method should only be used
2877 for obtaining an unused port in order to pass to an external program
2878 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2879 a parameter to a server-oriented class that doesn't give you direct
2880 access to the underlying socket used.
2881
2882 Finally, test_support.HOST has been introduced, which should be used
2883 for the host argument of any relevant socket calls (i.e. bind and
2884 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002885
2886 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002887 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002888 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2889 test_asynchat and test_socket_ssl.
2890
Georg Brandl3ee81df2008-05-17 18:14:43 +00002891 It is now possible for multiple instances of the regression test
2892 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00003171- Added the future_builtins module, which contains hex() and oct().
3172 These are the PEP 3127 version of these functions, designed to be
3173 compatible with the hex() and oct() builtins from Python 3.0. They
3174 differ slightly in their output formats from the existing, unchanged
3175 Python 2.6 builtins. The expected usage of the future_builtins
3176 module is:
3177 from future_builtins import hex, oct
3178
Eric Smith7ef40bf2008-02-20 23:34:22 +00003179- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3180 exponents for exponents with absolute value < 100. Follows C99
3181 standard. This is a change on Windows, which would use 3 digits.
3182 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3183 so that any alterations it does to the resulting string will be
3184 available in stringlib/formatter.h (for float.__format__).
3185
Eric Smith5a3c1352008-02-19 13:21:56 +00003186- Implemented PEP 3101, Advanced String Formatting. This adds a new
3187 builtin format(); a format() method for str and unicode; a
3188 __format__() method to object, str, unicode, int, long, float, and
3189 datetime; the class string.Formatter; and the C API
3190 PyObject_Format().
3191
Georg Brandl3ee81df2008-05-17 18:14:43 +00003192- Fixed several potential crashes, all caused by specially crafted
3193 __del__ methods exploiting objects in temporarily inconsistent
3194 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003195
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003196- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003197 prevent a possible crash: an Abstract Base Class would try to access
3198 a slot on a registered virtual subclass.

3204 in order to allow pymalloc to free more arenas. Python may give back
3205 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003206
Georg Brandl3ee81df2008-05-17 18:14:43 +00003207- Issue #2045: Fix an infinite recursion triggered when printing a
3208 subclass of collections.defaultdict, if its default_factory is set
3209 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003210
Christian Heimesf75dbef2008-02-08 00:11:31 +00003211- Fixed a minor memory leak in dictobject.c. The content of the free
3212 list was not freed on interpreter shutdown.
3213
Georg Brandl5a7eca12010-03-21 19:29:04 +00003214- Limit free list of method and built-in function objects to 256

3218 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003219 to compact the internal free lists of pre-allocted ints and floats.
3220
Georg Brandl3ee81df2008-05-17 18:14:43 +00003221- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3222 calls. Python expected the return type int but the fork familie
3223 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003224

Georg Brandl3ee81df2008-05-17 18:14:43 +00003231- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3232 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003233
Georg Brandl3ee81df2008-05-17 18:14:43 +00003234- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3235 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003236
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237- Patch #1473257: generator objects gain a gi_code attribute. This is
3238 the same object as the func_code attribute of the function that
3239 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003240
Georg Brandl3ee81df2008-05-17 18:14:43 +00003241- Issue #1920: "while 0" statements were completely removed by the
3242 compiler, even in the presence of an "else" clause, which is
3243 supposed to be run when the condition is false. Now the compiler
3244 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003245
Guido van Rossumeead05f2008-01-24 18:21:02 +00003246- A few crashers fixed: weakref_in_del.py (issue #1377858);
3247 loosing_dict_ref.py (issue #1303614, test67.py);
3248 borrowed_ref_[34].py (not in tracker).
3249
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003250- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003251 suppressed while an extension is loaded by calling SetErrorMode in
3252 dynload_win.c. The error is still reported properly.
3253
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003255 several extension methods and modules do not work without unicode
3256 support.
3257
Georg Brandl26543b12008-01-21 18:36:51 +00003258- Issue #1882: when compiling code from a string, encoding cookies in the
3259 second line of code were not always recognized correctly.
3260
Georg Brandl14404b62008-01-19 19:27:05 +00003261- Issue #1679: "0x" was taken as a valid integer literal.
3262
Georg Brandl6caad7d2008-01-26 14:19:22 +00003263- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003264 added.
3265
Christian Heimesc94e2b52008-01-14 04:13:37 +00003266- sys.float_info / PyFloat_GetInfo: The floating point information
3267 object was converted from a dict to a specialized structseq object.
3268
Georg Brandl3ee81df2008-05-17 18:14:43 +00003269- Patch #1816: Added sys.flags structseq. It exposes the status of
3270 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003271
Georg Brandl3ee81df2008-05-17 18:14:43 +00003272- Objects/structseq.c: Implemented new structseq representation. The
3273 patch makes structseqs (e.g. the return value of os.stat) more
3274 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003275
Georg Brandl3ee81df2008-05-17 18:14:43 +00003276- Patch #1700288: added a type attribute cache that caches method
3277 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003278
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003279- Bug #1776: __import__() no longer accepts filenames on any platform.
3280 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003281
Georg Brandlaed6c662008-01-07 17:25:53 +00003282- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3285 envvar and sys.dont_write_bytecode attribute. All these can be set
3286 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003287
Georg Brandl3ee81df2008-05-17 18:14:43 +00003288- Improve some exception messages when Windows fails to load an
3289 extension module. Now we get for example '%1 is not a valid Win32
3290 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003291
Georg Brandl3ee81df2008-05-17 18:14:43 +00003292- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003294- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3295 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003296
Christian Heimes0a8143f2007-12-18 23:22:54 +00003297- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003298 and INF. float("nan"), float("inf") and float("-inf") now work on
3299 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003300
Georg Brandl3ee81df2008-05-17 18:14:43 +00003301- Compiler now generates simpler and faster code for dictionary
3302 literals. The oparg for BUILD_MAP now indicates an estimated
3303 dictionary size. There is a new opcode, STORE_MAP, for adding
3304 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003305
Georg Brandl3ee81df2008-05-17 18:14:43 +00003306- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003311- Issue #1538: Avoid copying string in split/rsplit if the split char
3312 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003313
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003314- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003315 SystemError.
3316
Nick Coghlanef01d822007-12-03 12:55:17 +00003317- PEP 366: Allow explicit relative imports when executing modules
3318 inside packages with the -m switch via a new module level
3319 __package__ attribute.

3329
Georg Brandl3ee81df2008-05-17 18:14:43 +00003330- Issue #1460: The utf-7 incremental decoder did not accept truncated
3331 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003332
Georg Brandl3ee81df2008-05-17 18:14:43 +00003333- Patch #1739468: Directories and zipfiles containing a __main__.py
3334 file can now be directly executed by passing their name to the
3335 interpreter. The directory/zipfile is automatically inserted as the
3336 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003337
Georg Brandl3ee81df2008-05-17 18:14:43 +00003338- Issue #1265: Fix a problem with sys.settrace, if the tracing
3339 function uses a generator expression when at the same time the
3340 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003341
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003342- sets and frozensets now have an isdisjoint() method.
3343
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003344- optimize the performance of builtin.sum().
3345
Neal Norwitz44f326e2007-10-05 05:29:17 +00003346- Fix warnings found by the new version of the Coverity checker.
3347
Georg Brandl5a7eca12010-03-21 19:29:04 +00003348- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003349 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3350 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003351
Georg Brandl3ee81df2008-05-17 18:14:43 +00003352- Issue #1686386: Tuple's tp_repr did not take into account the
3353 possibility of having a self-referential tuple, which is possible
3354 from C code. Nor did object's tp_str consider that a type's tp_str
3355 could do something that could lead to an inifinite recursion.
3356 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3357 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003358
Georg Brandl3ee81df2008-05-17 18:14:43 +00003359- Issue #1164: It was possible to trigger deadlock when using the
3360 'print' statement to write to a file since the GIL was not released
3361 as needed. Now PyObject_Print() does the right thing along with
3362 various tp_print implementations of the built-in types and those in
3363 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003364
Georg Brandl3ee81df2008-05-17 18:14:43 +00003365- Issue #1147: Exceptions were directly allowing string exceptions in
3366 their throw() method even though string exceptions no longer
3367 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003368
Georg Brandl3ee81df2008-05-17 18:14:43 +00003369- Issue #1096: Prevent a segfault from getting the repr of a very
3370 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003371
Brett Cannon1e534b52007-09-07 04:18:30 +00003372- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003373 PyObject_Call() never calling back out to Python code to trigger
3374 recursion depth updates/checks. Required the creation of a static
3375 RuntimeError instance in case normalizing an exception put the
3376 recursion check value past its limit. Fixes crashers
3377 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003378
Georg Brandl3ee81df2008-05-17 18:14:43 +00003379- Patch #1031213: Decode source line in SyntaxErrors back to its

3383 with %G.
3384
Georg Brandl3ee81df2008-05-17 18:14:43 +00003385- Prevent expandtabs() on string and unicode objects from causing a
3386 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00003387

Georg Brandla5ea6892007-06-01 11:33:33 +00003391
Neal Norwitz0ac60192007-05-27 04:08:54 +00003392- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003393 __*__ attributes. (Some already existed, e.g., __doc__ and
3394 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003395
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003396- Add -3 option to the interpreter to warn about features that are
3397 deprecated and will be changed/removed in Python 3.0.
3398
Georg Brandl2134e752007-05-21 20:34:16 +00003399- Patch #1686487: you can now pass any mapping after '**' in function
3400 calls.
3401
Collin Winter62903052007-05-18 23:11:24 +00003402- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003403 "except E as target:". This is to provide forwards compatibility
3404 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003405
Brett Cannon229cee22007-05-05 01:34:02 +00003406- Deprecate BaseException.message as per PEP 352.
3407
Georg Brandl3ee81df2008-05-17 18:14:43 +00003408- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003409 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003410
Vinay Sajip8549ce32007-05-06 17:53:37 +00003411- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003412 setting a plain string, ie don't expand to single letter identifiers.
3413
Raymond Hettinger13936692007-04-11 18:40:58 +00003414- Request #1191699: Slices can now be pickled.
3415
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003416- Request #1193128: str.translate() now allows a None argument for
3417 translations that only remove characters without re-mapping the
3418 remaining characters.
3419
Georg Brandl5cb76c12007-03-21 09:00:39 +00003420- Patch #1682205: a TypeError while unpacking an iterable is no longer
3421 masked by a generic one with the message "unpack non-sequence".
3422
Neal Norwitzaa754b72007-03-21 06:39:48 +00003423- Remove unused file Python/fmod.c.
3424
Guido van Rossum143b5642007-03-23 04:58:42 +00003425- Bug #1683368: The object.__init__() and object.__new__() methods are
3426 now stricter in rejecting excess arguments. The only time when
3427 either allows excess arguments is when it is not overridden and the
3428 other one is. For backwards compatibility, when both are
3429 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003430 warning later). Also, type.__init__() insists on the same signature
3431 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003432
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3434 object to complex using its __complex__() method before falling back
3435 to the __float__() method. Therefore, the functions in the cmath
3436 module now can operate on objects that define a __complex__()
3437 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003438
Georg Brandl3ee81df2008-05-17 18:14:43 +00003439- Patch #1623563: allow __class__ assignment for classes with
3440 __slots__. The old and the new class are still required to have the
3441 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003442
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003446- Patch #1462488: Python no longer segfaults when
3447 ``object.__reduce_ex__()`` is called with an object that is faking
3448 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003449
Georg Brandl3ee81df2008-05-17 18:14:43 +00003450- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003453- Patch #1444529: the builtin compile() now accepts keyword arguments.
3454
Georg Brandl7b9c5552007-03-12 14:30:05 +00003455- Bug #1678647: write a newline after printing an exception in any
3456 case, even when converting the value to a string failed.
3457
Georg Brandl871f1bc2007-03-12 13:17:36 +00003458- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003459 its argument, if it exists. If not, it will work like before. This
3460 allows customizing the output of dir() in the presence of a
3461 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003462
Collin Winter276887b2007-03-12 16:11:39 +00003463- Patch #922167: Python no longer segfaults when faced with infinitely
3464 self-recursive reload() calls (as reported by bug #742342).
3465
Georg Brandl3ee81df2008-05-17 18:14:43 +00003466- Patch #1675981: remove unreachable code from ``type.__new__()``
3467 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00003468
Georg Brandl3ee81df2008-05-17 18:14:43 +00003469- Patch #1491866: change the complex() constructor to allow

3983
Facundo Batistad918a652007-04-24 13:54:38 +00003984- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003985 the client's request was successfully received, understood, and
3986 accepted. Now in these cases no error is raised in urllib (issue
3987 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003988

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003995- Added a timeout parameter to the constructor of other protocols
3996 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3997 work started with create_connection() and timeout in httplib, and
3998 closes patch #723312.
3999
Vinay Sajip8549ce32007-05-06 17:53:37 +00004000- Patch #1676823: Added create_connection() to socket.py, which may be
4001 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004002 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004003
Martin v. Löwis0af33882007-03-23 13:27:15 +00004004- Bug #978833: Revert r50844, as it broke _socketobject.dup.

4016 GNOME or KDE browser, depending on whether there is a session of one

4024
Georg Brandlf66b6032007-03-14 08:27:52 +00004025- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004026 AttributeError instead of an IOError when the server's response
4027 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004028
Georg Brandl3ee81df2008-05-17 18:14:43 +00004029- Patch #957650: "%var%" environment variable references are now
4030 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00004032
Georg Brandl3ee81df2008-05-17 18:14:43 +00004033- Patch #1429539: pdb now correctly initializes the __main__ module
4034 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004035 correctly now.
4036
Georg Brandlbad6f192007-03-13 21:32:56 +00004037- The nonobvious commands.getstatus() function is now deprecated.

4043
Georg Brandl3ee81df2008-05-17 18:14:43 +00004044- Patch #1530482: add pydoc.render_doc() which returns the
4045 documentation for a thing instead of paging it to stdout, which
4046 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004047
Georg Brandl3ee81df2008-05-17 18:14:43 +00004048- Patch #1533909: the timeit module now accepts callables in addition

4055 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00004057- Patch #1581073: add a flag to textwrap that prevents the dropping of

4059
Georg Brandl92a6bae2007-03-13 17:43:32 +00004060- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004061 are set for invalid interpolation sequences that would lead to
4062 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004063

4076
Georg Brandl94fe3f52007-03-13 09:32:11 +00004077- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00004078 field names in its exception message if you try to write a record
4079 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004097

4105 returned string up to the first NUL character.
4106

4116
Georg Brandl3ee81df2008-05-17 18:14:43 +00004117- unittest now verifies more of its assumptions. In particular,
4118 TestCase and TestSuite subclasses (not instances) are no longer
4119 accepted in TestSuite.addTest(). This should cause no
4120 incompatibility since it never made sense with ordinary subclasses
4121 -- the failure just occurred later, with a more cumbersome
4122 exception.

4132
Georg Brandl3ee81df2008-05-17 18:14:43 +00004133- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00004511 time so that opening a database previously created with the DB_DUP
4512 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4513 opens. Specifically: dictionary assignment to a DB object will
4514 replace all values for a given key when the database allows
4515 duplicate values. DB users should use DB.put(k, v) when they want
4516 to store duplicates; not DB[k] = v.

4523 characters with ASCII value less than 32. Also, it correctly quotes
4524 dots only if they occur on a single line, as opposed to the previous
4525 behavior of quoting dots if they are the second character of any
4526 line.
