12Core and Builtins
13-----------------
14
Antoine Pitroud4ae97b2008-08-29 18:39:48 +000015- Issue #3668: Fix a memory leak with the "s*" argument parser in
16 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
17 was correctly parsed but parsing of subsequent arguments failed.
18
Antoine Pitrou0668c622008-08-26 22:42:08 +000019- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
20 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
21 mechanism. In the process, fix a bug where isinstance() and issubclass(),
22 when given a tuple of classes as second argument, were looking up
23 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
24 type object.
25
Neal Norwitz18aa3882008-08-24 05:04:52 +000026- Fix crashes on memory allocation failure found with failmalloc.
27
28- Fix memory leaks found with valgrind and update suppressions file.
29
30- Fix compiler warnings in opt mode which would lead to invalid memory reads.
31
32- Fix problem using wrong name in decimal module reported by pychecker.
33
Christian Heimesfb1813c2008-08-22 19:34:15 +000034- Issue #3642: Changed type of numarenas from uint to size_t
35 in order to silence a compilier warning on 64bit OSes.
36
Christian Heimes7d4c3172008-08-22 19:47:25 +000037- Silenced another compiler warning about a used but not defined
38 function 'stringlib_contains_obj'.
39
Benjamin Peterson712ee922008-08-24 18:10:20 +000040- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
41 ``__delslice__``.

Christian Heimesa27a62e2008-08-22 19:55:54 +000051- Silenced a trivial compiler warning in the sqlite module.
52
Christian Heimes1cc69632008-08-22 20:10:27 +000053- Fixed two format strings in the _collections module.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +000062What's New in Python 2.6 beta 3?
63================================
64
Barry Warsaw07a4a382008-08-21 01:15:08 +000065*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +000066
67Core and Builtins
68-----------------
69
Guido van Rossumf8402962008-08-20 15:01:50 +000070- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
71 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
72 extensions do not automatically benefit from the class attribute
73 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
74 to their tp_flags field if they care. This is a backwards
75 compatibility feature; in 3.0, all types will use the cache by
76 default.
77
Benjamin Petersonf647dc12008-08-20 01:27:30 +000078- Keyword arguments can now follow starred arguments. (``f(a, *args,
79 keyword=23)`` is now valid syntax.)
80
Thomas Heller0ad5ae02008-08-19 19:25:04 +000081- ctypes function pointers that are COM methods have a boolean True
82 value again.
83
Martin v. Löwisf91d46a2008-08-12 14:49:50 +000084- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
85 by denying s# to parse objects that have a releasebuffer procedure,
86 and introducing s*.
87
Georg Brandl1e13ea92008-08-11 09:07:59 +000088- Issue #3537: Fix an assertion failure when an empty but presized dict
89 object was stored in the freelist.
90
Mark Dickinsonb6467572008-08-04 21:30:09 +000091- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
92 ValueError consistently across platforms.
93
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +000094- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
95 (64bit Unix, for example), unichr() would truncate its argument and return
96 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
97
Neal Norwitze7d8be82008-07-31 17:17:14 +000098- Apply security patches from Apple.
99
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000100- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
101 PyErr_ExceptionMatches returns 0 when an exception occurs there.
102
Antoine Pitrou92f82162008-07-25 22:22:08 +0000103- Issue #1819: function calls with several named parameters are now on
104 average 35% faster (as measured by pybench).
105
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000106- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
107 the python debugger steps into a class statement: the free variables (local
108 variables defined in an outer scope) would be deleted from the outer scope.
109
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000110- Issue #2620: Overflow checking when allocating or reallocating memory
111 was not always being done properly in some python types and extension
112 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
113 all been updated to perform better checks and places in the code that
114 would previously leak memory on the error path when such an allocation
115 failed have been fixed.
116
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000117Library
118-------
119
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +0000120- Issue #3612: Added some missing basic types in ctypes.wintypes.
121
Benjamin Petersone977ad42008-08-20 01:42:01 +0000122- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
123 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
124
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000125- Issue #2234: distutils failed for some versions of the cygwin compiler. The
126 version reported by these tools does not necessarily follow the python
127 version numbering scheme, so the module is less strict when parsing it.
128
Nick Coghlanf70385a2008-08-18 12:42:46 +0000129- Issue #2235: Added Py3k warnings for types which will become unhashable
130 under the stricter __hash__ inheritance rules in 3.0. Several types
131 which did not meet the rules for hash invariants and were already
132 unhashable in 3.0 have now been explicitly flagged as unhashable in
133 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
134 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
135
Brett Cannon88f801d2008-08-18 00:46:22 +0000136- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
137 imported into the module but exposed as part of the module's API.
138
Brett Cannon7b96f072008-08-18 00:41:11 +0000139- Remove an unneeded import of abc.ABCMeta from 'inspect'.
140
Brett Cannon46225e72008-08-18 00:36:52 +0000141- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
142
Brett Cannon25c9d6a2008-08-17 22:10:11 +0000143- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
144
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000145- Issue #3575: Incremental decoder's decode function now takes bytearray
146 by using 's*' instead of 't#'.
147
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000148- Issue #2222: Fixed reference leak when occured os.rename()
149 fails unicode conversion on 2nd parameter. (windows only)
150
Facundo Batista94f243a2008-08-17 03:38:39 +0000151- Issue 2464. urllib2 now supports a malformation in the URL received
152 in a redirect.
153
Brett Cannonabe423e2008-08-16 21:47:07 +0000154- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000155 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000156
Facundo Batistaeb90b782008-08-16 14:44:07 +0000157- Issue #2776: fixed small issue when handling an URL with double slash
158 after a 302 response in the case of not going through a proxy.
159
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000160- Issue #2676: in the email package, content-type parsing was hanging on
161 pathological input because of quadratic or exponential behaviour of a
162 regular expression.
163
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000164- Issue #3476: binary buffered reading through the new "io" library is now
165 thread-safe.
166
Brett Cannonbf3157b2008-08-14 05:00:03 +0000167- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
168 since mimetools itself is deprecated. Because modules are cached, all
169 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
170
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000171- Issue #3134: shutil referenced undefined WindowsError symbol.
172
Robert Schuppenies14646332008-08-10 11:01:53 +0000173- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
174 menu entries were not deleted.
175
Brett Cannon83e81842008-08-09 23:30:55 +0000176- Copied the implementation of reduce() to _functools.reduce() to have a
177 version that did not raise a DeprecationWarning under -3.
178
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000179- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
180 a MemoryError rather than silently stop the iteration.
181
Guido van Rossum59ce9012008-08-09 14:55:34 +0000182- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
183 to _sre.compile() will now be rejected. This should not affect anybody
184 since the re.compile() function never generates invalid re-bytecode.
185
Skip Montanaroa032bf42008-08-08 22:52:51 +0000186- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
187 upon first access it can be automatically initialized from the csv file if
188 it wasn't initialized during instantiation.
189
Brett Cannon3aa2a492008-08-06 22:28:09 +0000190- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
191 the reload() built-in has been removed.
192
Brett Cannon7e30b672008-08-04 21:52:25 +0000193- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +0000194 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +0000195 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
196 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
197 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
198 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
199 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Lars Gustäbel727bd0b2008-08-02 11:26:39 +0000201- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
202 raised an AttributeError.
203
Benjamin Peterson01a24322008-07-28 23:35:27 +0000204- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +0000205 asking for a specific length. This problem only affected files opened
206 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000207

212
Raymond Hettinger8c664e82008-07-25 18:43:33 +0000213- Issue 1592: Improve error reporting when operations are attempted
214 on a closed shelf.

Georg Brandlf9efabb2008-07-23 15:16:45 +0000216- Deprecate the "ast" parser function aliases.
217
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000218- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.

226- Issue #3389: Allow resolving dotted names for handlers in logging
227 configuration files.
228
229- Deprecate the sunaudio module for removal in Python 3.0.
230
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000231- Issue #3394: zipfile.writestr sets external attributes when passed a
232 file name rather than a ZipInfo instance, so files are extracted with
233 mode 0600 rather than 000 under Unix.
234
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000235- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
236 argument in python 2.5, this broke code that subclassed Popen to include its
237 own poll method. Fixed my moving _deadstate to an _internal_poll method.
238
Martin v. Löwis8dbf3642008-08-01 14:10:26 +0000239Build

245-------------
246
Nick Coghlan6e8fef02008-08-18 13:14:22 +0000247- Issue #2235: the C API function PyObject_HashNotImplemented and its
248 interaction with the tp_hash slot (added in 2.6b2) are now documented
249
Nick Coghlan2a0c2b12008-08-04 12:47:17 +0000250- Issue #643841: The language reference now provides more detailed
251 coverage of the lookup process for special methods. The disclaimers
252 regarding lack of coverage of new-style classes have also been
253 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000256What's New in Python 2.6 beta 2?
257================================
258
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000259*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000261Core and Builtins
262-----------------
263
Georg Brandl3e483f62008-07-16 22:57:41 +0000264- Issue #3156: Fix inconsistent behavior of the bytearray type: all
265 its methods now allow for items objects that can be converted to
266 an integer using operator.index().
267
Mark Dickinson64b7e502008-07-16 09:40:03 +0000268- Issue #3360: Fix incorrect parsing of '020000000000.0', which
269 produced a ValueError instead of giving the correct float.
270
Eric Smitha5fa5a22008-07-16 00:11:49 +0000271- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
272 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
273
Mark Dickinson7103aa42008-07-15 19:08:33 +0000274- Issue #3008: the float type has a new instance method 'float.hex'
275 and a new class method 'float.fromhex' to convert floating-point
276 numbers to and from hexadecimal strings, respectively.
277
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000278- Issue #2235: __hash__ is once again inherited by default. To allow
279 collections.Hashable to remain meaningful in the presence of the
280 default hash implementation (object.__hash__), it is now possible
281 to explicit block inheritance of hash by setting __hash__=None at
282 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
283 level.
284
Nick Coghlanb028f502008-07-13 14:52:36 +0000285- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
286 the parent module cannot be found while performing an absolute import.
287 This means that an incorrectly defined __package__ attribute will
288 now only prevent relative imports in that module rather than causing
289 all imports from that module to fail.
290
Nick Coghlan14ff9942008-07-08 14:21:42 +0000291- Issue #2517: Allow unicode messages in Exceptions again by correctly
292 bypassing the instance dictionary when looking up __unicode__ on
293 new-style classes.
294
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000295- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
296 set to a custom object whose write() method happens to install
297 another file in sys.stdout.
298
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000299- Issue #3088: Corrected a race condition in classes derived from
300 threading.local: the first member set by a thread could be saved in
301 another thread's dictionary.
302
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000303- Issue #3004: Minor change to slice.indices(): the start and stop
304 arguments are now treated identically, making the behaviour easier
305 to describe and understand. For example, slice(None, -10,
306 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
307 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
308 10, -1).
309
Georg Brandl278fc502008-07-19 12:46:12 +0000310- Issue #3219: Calling a function with repeated keyword arguments,
311 f(a=2, a=23), would not cause a syntax error. This was a regression
312 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +0000313
Georg Brandl278fc502008-07-19 12:46:12 +0000314- Issue #2862: Make int and float freelist management consistent with
315 other freelists. Changes their CompactFreeList apis into
316 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +0000317

320
Thomas Heller57adf222008-08-14 19:10:48 +0000321- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
322 api functions without holding the GIL, which could lead to a fatal
323 error when they failed.
324

757
Brett Cannonb61d8012008-05-11 23:39:04 +0000758- ``Lib/lib-old`` is now added to sys.path.
759
Ronald Oussoren5640ce22008-06-05 12:58:24 +0000760- On MacOS X it is now possible to install the framework in 64-bit
761 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +0000762 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +0000763
764 This is controlled by the configure argument ``--with-universal-archs``:
765
766 - ``--with-universal-archs=all``: install 4-way universal
767
768 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
769
770 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
771
772 This option should be used in combination with ``--enable-universalsdk=``.
773
774 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

811 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +0000812
Christian Heimese74c8f22008-04-19 02:23:57 +0000813- Added kill, terminate and send_signal(sig) to subprocess.Popen.
814
Georg Brandl3ee81df2008-05-17 18:14:43 +0000815- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
816 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +0000817

Georg Brandl3ee81df2008-05-17 18:14:43 +0000824- Issue #1631171: Re-implement the 'warnings' module in C (the
825 original Python code has been kept as backup). This will allow for
826 using the 'warning's machinery in such places as the parser where
827 use of pure Python code is not possible. Both the ``showarning()``
828 and ``formatwarning()`` gain an optional 'line' argument which is
829 not called by default for backwards-compatibility reasons. Setting
830 ``warnings.showwarning()`` to an implementation that lacks support
831 for the ``line`` argument will raise a DeprecationWarning.

855
Gregory P. Smithd59fefb2008-04-22 08:11:33 +0000856- The getpass module has been improved on Unix. It now uses /dev/tty
857 by default and uses stderr instead of stdout. A GetPassWarning is
858 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +0000859

Georg Brandl3ee81df2008-05-17 18:14:43 +0000873- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +0000874 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +0000894- Issue #2550: The approach used by client/server code for obtaining
895 ports to listen on in network-oriented tests has been refined in an
896 effort to facilitate running multiple instances of the entire
897 regression test suite in parallel without issue.
898 test_support.bind_port() has been fixed such that it will always
899 return a unique port -- which wasn't always the case with the
900 previous implementation, especially if socket options had been set
901 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
902 new implementation of bind_port() will actually raise an exception
903 if it is passed an AF_INET/SOCK_STREAM socket with either the
904 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
905 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
906 the socket it's been passed. This currently only applies to
907 Windows. This option prevents any other sockets from binding to the
908 host/port we've bound to, thus removing the possibility of the
909 'non-deterministic' behaviour, as Microsoft puts it, that occurs
910 when a second SOCK_STREAM socket binds and accepts to a host/port
911 that's already been bound by another socket. The optional preferred
912 port parameter to bind_port() has been removed. Under no
913 circumstances should tests be hard coding ports!
914
915 test_support.find_unused_port() has also been introduced, which will
916 pass a temporary socket object to bind_port() in order to obtain an
917 unused port. The temporary socket object is then closed and
918 deleted, and the port is returned. This method should only be used
919 for obtaining an unused port in order to pass to an external program
920 (i.e. the -accept [port] argument to openssl's s_server mode) or as
921 a parameter to a server-oriented class that doesn't give you direct
922 access to the underlying socket used.
923
924 Finally, test_support.HOST has been introduced, which should be used
925 for the host argument of any relevant socket calls (i.e. bind and
926 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +0000927
928 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +0000929 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +0000930 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
931 test_asynchat and test_socket_ssl.
932
Georg Brandl3ee81df2008-05-17 18:14:43 +0000933 It is now possible for multiple instances of the regression test
934 suite to run in parallel without issue.

1200Core and builtins
1201-----------------
1202
Fred Drakea8ee94b2008-03-01 02:45:07 +00001203- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001204 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001205
Georg Brandlad61bc82008-02-23 15:11:18 +00001206- Issue #2067: file.__exit__() now calls subclasses' close() method.
1207
1208- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001209
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001210- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001211 issue 215555 for a discussion.
1212
Eric Smitha73fbe72008-02-23 03:09:44 +00001213- Added the future_builtins module, which contains hex() and oct().
1214 These are the PEP 3127 version of these functions, designed to be
1215 compatible with the hex() and oct() builtins from Python 3.0. They
1216 differ slightly in their output formats from the existing, unchanged
1217 Python 2.6 builtins. The expected usage of the future_builtins
1218 module is:
1219 from future_builtins import hex, oct
1220
Eric Smith7ef40bf2008-02-20 23:34:22 +00001221- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1222 exponents for exponents with absolute value < 100. Follows C99
1223 standard. This is a change on Windows, which would use 3 digits.
1224 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1225 so that any alterations it does to the resulting string will be
1226 available in stringlib/formatter.h (for float.__format__).
1227
Eric Smith5a3c1352008-02-19 13:21:56 +00001228- Implemented PEP 3101, Advanced String Formatting. This adds a new
1229 builtin format(); a format() method for str and unicode; a
1230 __format__() method to object, str, unicode, int, long, float, and
1231 datetime; the class string.Formatter; and the C API
1232 PyObject_Format().
1233
Georg Brandl3ee81df2008-05-17 18:14:43 +00001234- Fixed several potential crashes, all caused by specially crafted
1235 __del__ methods exploiting objects in temporarily inconsistent
1236 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001237
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001238- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001239 prevent a possible crash: an Abstract Base Class would try to access
1240 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001241
Georg Brandl3ee81df2008-05-17 18:14:43 +00001242- Fixed repr() and str() of complex numbers with infinity or nan as
1243 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001244
Georg Brandl3ee81df2008-05-17 18:14:43 +00001245- Clear all free lists during a gc.collect() of the highest generation
1246 in order to allow pymalloc to free more arenas. Python may give back
1247 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001248
Georg Brandl3ee81df2008-05-17 18:14:43 +00001249- Issue #2045: Fix an infinite recursion triggered when printing a
1250 subclass of collections.defaultdict, if its default_factory is set
1251 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001252
Christian Heimesf75dbef2008-02-08 00:11:31 +00001253- Fixed a minor memory leak in dictobject.c. The content of the free
1254 list was not freed on interpreter shutdown.
1255
Georg Brandl3ee81df2008-05-17 18:14:43 +00001256- Limit free list of method and builtin function objects to 256
1257 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001258
Georg Brandl3ee81df2008-05-17 18:14:43 +00001259- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1260 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001261 to compact the internal free lists of pre-allocted ints and floats.
1262
Georg Brandl3ee81df2008-05-17 18:14:43 +00001263- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1264 calls. Python expected the return type int but the fork familie
1265 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001266
Georg Brandl3ee81df2008-05-17 18:14:43 +00001267- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1268 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001269
Georg Brandl3ee81df2008-05-17 18:14:43 +00001270- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1271 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00001272
Georg Brandl3ee81df2008-05-17 18:14:43 +00001273- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
1274 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00001275
Georg Brandl3ee81df2008-05-17 18:14:43 +00001276- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1277 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001278
Georg Brandl3ee81df2008-05-17 18:14:43 +00001279- Patch #1473257: generator objects gain a gi_code attribute. This is
1280 the same object as the func_code attribute of the function that
1281 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001282
Georg Brandl3ee81df2008-05-17 18:14:43 +00001283- Issue #1920: "while 0" statements were completely removed by the
1284 compiler, even in the presence of an "else" clause, which is
1285 supposed to be run when the condition is false. Now the compiler
1286 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001287
Guido van Rossumeead05f2008-01-24 18:21:02 +00001288- A few crashers fixed: weakref_in_del.py (issue #1377858);
1289 loosing_dict_ref.py (issue #1303614, test67.py);
1290 borrowed_ref_[34].py (not in tracker).
1291
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001292- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001293 suppressed while an extension is loaded by calling SetErrorMode in
1294 dynload_win.c. The error is still reported properly.
1295
Georg Brandl3ee81df2008-05-17 18:14:43 +00001296- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001297 several extension methods and modules do not work without unicode
1298 support.
1299
Georg Brandl26543b12008-01-21 18:36:51 +00001300- Issue #1882: when compiling code from a string, encoding cookies in the
1301 second line of code were not always recognized correctly.
1302
Georg Brandl14404b62008-01-19 19:27:05 +00001303- Issue #1679: "0x" was taken as a valid integer literal.
1304
Georg Brandl6caad7d2008-01-26 14:19:22 +00001305- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001306 added.
1307
Christian Heimesc94e2b52008-01-14 04:13:37 +00001308- sys.float_info / PyFloat_GetInfo: The floating point information
1309 object was converted from a dict to a specialized structseq object.
1310
Georg Brandl3ee81df2008-05-17 18:14:43 +00001311- Patch #1816: Added sys.flags structseq. It exposes the status of
1312 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001313
Georg Brandl3ee81df2008-05-17 18:14:43 +00001314- Objects/structseq.c: Implemented new structseq representation. The
1315 patch makes structseqs (e.g. the return value of os.stat) more
1316 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001317
Georg Brandl3ee81df2008-05-17 18:14:43 +00001318- Patch #1700288: added a type attribute cache that caches method
1319 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00001320
Neal Norwitz3fc15b82008-01-10 05:42:58 +00001321- Bug #1776: __import__() no longer accepts filenames on any platform.
1322 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00001323
Georg Brandlaed6c662008-01-07 17:25:53 +00001324- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
1325
Georg Brandl3ee81df2008-05-17 18:14:43 +00001326- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
1327 envvar and sys.dont_write_bytecode attribute. All these can be set
1328 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00001329
Georg Brandl3ee81df2008-05-17 18:14:43 +00001330- Improve some exception messages when Windows fails to load an
1331 extension module. Now we get for example '%1 is not a valid Win32
1332 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00001333
Georg Brandl3ee81df2008-05-17 18:14:43 +00001334- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001336- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
1337 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00001338
Christian Heimes0a8143f2007-12-18 23:22:54 +00001339- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00001340 and INF. float("nan"), float("inf") and float("-inf") now work on
1341 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001342
Georg Brandl3ee81df2008-05-17 18:14:43 +00001343- Compiler now generates simpler and faster code for dictionary
1344 literals. The oparg for BUILD_MAP now indicates an estimated
1345 dictionary size. There is a new opcode, STORE_MAP, for adding
1346 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00001347
Georg Brandl3ee81df2008-05-17 18:14:43 +00001348- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001350- Issue #1620: New property decorator syntax was modifying the
1351 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00001352
Georg Brandl3ee81df2008-05-17 18:14:43 +00001353- Issue #1538: Avoid copying string in split/rsplit if the split char
1354 is not found.

1358
Nick Coghlanef01d822007-12-03 12:55:17 +00001359- PEP 366: Allow explicit relative imports when executing modules
1360 inside packages with the -m switch via a new module level
1361 __package__ attribute.
1362
Georg Brandl3ee81df2008-05-17 18:14:43 +00001363- Issue #1402: Fix a crash on exit, when another thread is still
1364 running, and if the deallocation of its frames somehow calls the
1365 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00001366

1376 file can now be directly executed by passing their name to the
1377 interpreter. The directory/zipfile is automatically inserted as the
1378 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00001379
Georg Brandl3ee81df2008-05-17 18:14:43 +00001380- Issue #1265: Fix a problem with sys.settrace, if the tracing
1381 function uses a generator expression when at the same time the
1382 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00001383
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00001384- sets and frozensets now have an isdisjoint() method.
1385
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00001386- optimize the performance of builtin.sum().
1387
Neal Norwitz44f326e2007-10-05 05:29:17 +00001388- Fix warnings found by the new version of the Coverity checker.
1389
Georg Brandl3ee81df2008-05-17 18:14:43 +00001390- The enumerate() builtin function is no longer bounded to sequences
1391 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
1392 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00001393
Georg Brandl3ee81df2008-05-17 18:14:43 +00001394- Issue #1686386: Tuple's tp_repr did not take into account the
1395 possibility of having a self-referential tuple, which is possible
1396 from C code. Nor did object's tp_str consider that a type's tp_str
1397 could do something that could lead to an inifinite recursion.
1398 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
1399 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00001400
Georg Brandl3ee81df2008-05-17 18:14:43 +00001401- Issue #1164: It was possible to trigger deadlock when using the
1402 'print' statement to write to a file since the GIL was not released
1403 as needed. Now PyObject_Print() does the right thing along with

Georg Brandl3ee81df2008-05-17 18:14:43 +00001407- Issue #1147: Exceptions were directly allowing string exceptions in
1408 their throw() method even though string exceptions no longer
1409 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00001410
Georg Brandl3ee81df2008-05-17 18:14:43 +00001411- Issue #1096: Prevent a segfault from getting the repr of a very
1412 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00001413
Brett Cannon1e534b52007-09-07 04:18:30 +00001414- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00001415 PyObject_Call() never calling back out to Python code to trigger
1416 recursion depth updates/checks. Required the creation of a static
1417 RuntimeError instance in case normalizing an exception put the
1418 recursion check value past its limit. Fixes crashers
1419 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00001420

Neal Norwitz0ac60192007-05-27 04:08:54 +00001434- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00001435 __*__ attributes. (Some already existed, e.g., __doc__ and
1436 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00001437
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00001438- Add -3 option to the interpreter to warn about features that are

1442 calls.
1443
Collin Winter62903052007-05-18 23:11:24 +00001444- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00001445 "except E as target:". This is to provide forwards compatibility
1446 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00001447
Brett Cannon229cee22007-05-05 01:34:02 +00001448- Deprecate BaseException.message as per PEP 352.
1449
Georg Brandl3ee81df2008-05-17 18:14:43 +00001450- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00001451 inherited from a builtin base.
1452
Vinay Sajip8549ce32007-05-06 17:53:37 +00001453- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00001454 setting a plain string, ie don't expand to single letter identifiers.
1455
Raymond Hettinger13936692007-04-11 18:40:58 +00001456- Request #1191699: Slices can now be pickled.
1457
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00001458- Request #1193128: str.translate() now allows a None argument for
1459 translations that only remove characters without re-mapping the
1460 remaining characters.
1461
Georg Brandl5cb76c12007-03-21 09:00:39 +00001462- Patch #1682205: a TypeError while unpacking an iterable is no longer
1463 masked by a generic one with the message "unpack non-sequence".
1464
Neal Norwitzaa754b72007-03-21 06:39:48 +00001465- Remove unused file Python/fmod.c.
1466
Guido van Rossum143b5642007-03-23 04:58:42 +00001467- Bug #1683368: The object.__init__() and object.__new__() methods are
1468 now stricter in rejecting excess arguments. The only time when
1469 either allows excess arguments is when it is not overridden and the
1470 other one is. For backwards compatibility, when both are
1471 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00001472 warning later). Also, type.__init__() insists on the same signature
1473 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00001474
Georg Brandl3ee81df2008-05-17 18:14:43 +00001475- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
1476 object to complex using its __complex__() method before falling back
1477 to the __float__() method. Therefore, the functions in the cmath
1478 module now can operate on objects that define a __complex__()
1479 method.
Georg Brandl2b869942007-03-17 16:08:45 +00001480
Georg Brandl3ee81df2008-05-17 18:14:43 +00001481- Patch #1623563: allow __class__ assignment for classes with
1482 __slots__. The old and the new class are still required to have the
1483 same slot names.

1489 ``object.__reduce_ex__()`` is called with an object that is faking
1490 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00001491
Georg Brandl3ee81df2008-05-17 18:14:43 +00001492- Patch #1680015: Don't modify __slots__ tuple if it contains an

1496
Georg Brandl7b9c5552007-03-12 14:30:05 +00001497- Bug #1678647: write a newline after printing an exception in any
1498 case, even when converting the value to a string failed.
1499
Georg Brandl871f1bc2007-03-12 13:17:36 +00001500- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00001501 its argument, if it exists. If not, it will work like before. This
1502 allows customizing the output of dir() in the presence of a
1503 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00001504
Collin Winter276887b2007-03-12 16:11:39 +00001505- Patch #922167: Python no longer segfaults when faced with infinitely
1506 self-recursive reload() calls (as reported by bug #742342).
1507

1512 parthensized forms. This means complex(repr(x)) now works instead of
1513 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00001514
Georg Brandlaa2321b2007-03-07 00:40:28 +00001515- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00001516 makes the filenames the warning module prints much more sensible
1517 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00001518
Georg Brandl49aafc92007-03-07 00:34:46 +00001519- Variant of patch #697613: don't exit the interpreter on a SystemExit
1520 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00001521 variable is given, but break into the interactive interpreter just
1522 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00001530- Patch #1674228: when assigning a slice (old-style), check for the
1531 sq_ass_slice instead of the sq_slice slot.
1532
Georg Brandl3ee81df2008-05-17 18:14:43 +00001533- When printing an unraisable error, don't print exceptions. before
1534 the name. This duplicates the behavior whening normally printing
1535 exceptions.

1544 created a weakref on itself during a __del__ call for new-style
1545 classes (classic classes still have the bug).

2144 Python would crash instead of raising an error.
2145
Thomas Hellerc2f77252007-03-09 19:21:28 +00002146- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
2147 returned string up to the first NUL character.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002159- unittest now verifies more of its assumptions. In particular,
2160 TestCase and TestSuite subclasses (not instances) are no longer
2161 accepted in TestSuite.addTest(). This should cause no
2162 incompatibility since it never made sense with ordinary subclasses
2163 -- the failure just occurred later, with a more cumbersome
2164 exception.

2448 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00002449
Georg Brandl3ee81df2008-05-17 18:14:43 +00002450- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00002451 that the SMTP.starttls() caller no longer needs to call ehlo()
2452 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00002453 does not claim to support starttls. Adds the
2454 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00002553 time so that opening a database previously created with the DB_DUP
2554 or DB_DUPSORT flag set will keep the proper behavior on subsequent
2555 opens. Specifically: dictionary assignment to a DB object will
2556 replace all values for a given key when the database allows
2557 duplicate values. DB users should use DB.put(k, v) when they want
2558 to store duplicates; not DB[k] = v.

2565 characters with ASCII value less than 32. Also, it correctly quotes
2566 dots only if they occur on a single line, as opposed to the previous
2567 behavior of quoting dots if they are the second character of any
2568 line.

Neal Norwitz92422fb2006-08-18 03:57:54 +00002890C API
2891-----
2892
Georg Brandl3ee81df2008-05-17 18:14:43 +00002893- Unified naming convention for free lists and their limits. All free
2894 lists in Object/ are named ``free_list``, the counter ``numfree``
2895 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
2896 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00002897
Georg Brandl3ee81df2008-05-17 18:14:43 +00002898- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
2899 to ``PyTuple_SetItem``, it can be used to populate a brand new
2900 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00002901
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002902- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002904- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
2905 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
2906 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00002907
2908- Patch #1720595: add T_BOOL to the range of structmember types.
2909
2910- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
2911 ``PyFloat_GetInfo()`` to the float API.
2912
Georg Brandl3ee81df2008-05-17 18:14:43 +00002913- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
2914 of w# format code incorrectly truncated the length to an int, even
2915 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
2916 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00002917
Georg Brandl3ee81df2008-05-17 18:14:43 +00002918- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
2919 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002921- PEP 3123: Provide forward compatibility with Python 3.0, while
2922 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
2923 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00002924
Georg Brandl3ee81df2008-05-17 18:14:43 +00002925- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
2926 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00002927
2928- Patch #1733960: Allow T_LONGLONG to accept ints.
2929
2930- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
2931

2935
2936- Fix some leftovers from the conversion from int to Py_ssize_t
2937 (relevant to strings and sequences of more than 2**31 items).
2938
2939- Make _PyGILState_NoteThreadState() static, it was not used anywhere
2940 outside of pystate.c and should not be necessary.
2941
Georg Brandl3ee81df2008-05-17 18:14:43 +00002942- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
2943 absolute imports. In earlier versions they might have used relative
2944 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00002945
Georg Brandl3ee81df2008-05-17 18:14:43 +00002946- Added case insensitive comparison methods ``PyOS_stricmp(char*,
2947 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00002948
Georg Brandl3ee81df2008-05-17 18:14:43 +00002949- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

2955
Georg Brandl3ee81df2008-05-17 18:14:43 +00002956- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
2957 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
2958 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
2959 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00002960
Georg Brandl3ee81df2008-05-17 18:14:43 +00002961- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

2973
Georg Brandl3ee81df2008-05-17 18:14:43 +00002974- Removed the macfs module. It had been deprecated since Python 2.5.
2975 This lead to the deprecation of macostools.touched() as it relied
2976 solely on macfs and was a no-op under OS X.
