650 output compared to previous Python versions.
651
Lars Gustäbel9e2a09a2009-03-22 20:22:29 +0000652- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop

745
Antoine Pitrou19fec8b2009-01-21 00:56:37 +0000746- Issue #5008: When a file is opened in append mode with the new IO library,
747 do an explicit seek to the end of file (so that e.g. tell() returns the
748 file size rather than 0). This is consistent with the behaviour of the
749 traditional 2.x file object.

784 302 conformant loader) will now work correctly in most cases (they
785 are still subject to the constraints that exist for all code running
786 from inside a module loaded via a PEP 302 loader and attempting to

945What's New in Python 2.6.1
946==========================
947
948*Release date: 04-Dec-2008*
949
950Core and Builtins
951-----------------
952
953- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
954 interpreter to abort ("Fatal Python error: Could not reset the stack!")
955 instead of throwing a MemoryError.
956
957- Issue #4367: Python would segfault during compiling when the unicodedata
958 module couldn't be imported and \N escapes were present.
959
960- Issue #4348: Some bytearray methods returned that didn't cause any change to
961 the bytearray, returned the same bytearray instead of a copy.
962
963- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
964
965- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
966
967- Issue #4048: The parser module now correctly validates relative imports.
968
969- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
970 exec statement.
971
972- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
973 method does not return iterators for the 4th and 5th items.
974
975- Issue #4209: Enabling unicode_literals and the print_function in the same
976 __future__ import didn't work.
977
978- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
979 returned a path longer than MAX_PATH. (But It's doubtful this code path is
980 really executed because I cannot move to such directory on win2k)
981
982- Issue #4069: When set.remove(element) is used with a set element, the element
983 is temporarily replaced with an equivalent frozenset. But the eventual
984 KeyError would always report the empty frozenset([]) as the missing key. Now
985 it correctly refers to the initial element.
986
987- Fixed C99 style comments in several files. Python is now C89 compatible
988 again.
989
990Library

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001135- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1136
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001137- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1138 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1139 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1140 ``printf`` function, whereas PyString_FromFormat has an independent
1141 implementation and uses "%zd" on all platforms for size_t values.
1142 This makes a difference on win64, where ``printf`` needs "%Id" to display
1143 64bit values.

1149 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001160 was correctly parsed but parsing of subsequent arguments failed.
1161
Vinay Sajip35e3b032008-09-01 14:33:59 +00001162- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001163 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1164 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1165 when given a tuple of classes as second argument, were looking up
1166 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1167 type object.
1168

1308Core and Builtins
1309-----------------
1310
Guido van Rossumf8402962008-08-20 15:01:50 +00001311- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1312 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1313 extensions do not automatically benefit from the class attribute
1314 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1315 to their tp_flags field if they care. This is a backwards
1316 compatibility feature; in 3.0, all types will use the cache by
1317 default.
1318
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001319- Keyword arguments can now follow starred arguments. (``f(a, *args,
1320 keyword=23)`` is now valid syntax.)
1321
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001322- ctypes function pointers that are COM methods have a boolean True
1323 value again.
1324
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001325- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1326 by denying s# to parse objects that have a releasebuffer procedure,
1327 and introducing s*.
1328
Georg Brandl1e13ea92008-08-11 09:07:59 +00001329- Issue #3537: Fix an assertion failure when an empty but presized dict
1330 object was stored in the freelist.
1331
Mark Dickinsonb6467572008-08-04 21:30:09 +00001332- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1333 ValueError consistently across platforms.
1334
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001335- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1336 (64bit Unix, for example), unichr() would truncate its argument and return
1337 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1338
Neal Norwitze7d8be82008-07-31 17:17:14 +00001339- Apply security patches from Apple.
1340
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001341- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1342 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1343
Antoine Pitrou92f82162008-07-25 22:22:08 +00001344- Issue #1819: function calls with several named parameters are now on
1345 average 35% faster (as measured by pybench).
1346
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001347- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1348 the python debugger steps into a class statement: the free variables (local
1349 variables defined in an outer scope) would be deleted from the outer scope.
1350
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001351- Issue #2620: Overflow checking when allocating or reallocating memory
1352 was not always being done properly in some python types and extension
1353 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1354 all been updated to perform better checks and places in the code that
1355 would previously leak memory on the error path when such an allocation
1356 failed have been fixed.

1359-------
1360
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001361- Issue #3612: Added some missing basic types in ctypes.wintypes.
1362
Benjamin Petersone977ad42008-08-20 01:42:01 +00001363- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1364 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1365
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001366- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1367 version reported by these tools does not necessarily follow the python
1368 version numbering scheme, so the module is less strict when parsing it.
1369
Nick Coghlanf70385a2008-08-18 12:42:46 +00001370- Issue #2235: Added Py3k warnings for types which will become unhashable
1371 under the stricter __hash__ inheritance rules in 3.0. Several types
1372 which did not meet the rules for hash invariants and were already
1373 unhashable in 3.0 have now been explicitly flagged as unhashable in
1374 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1375 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1376
Brett Cannon88f801d2008-08-18 00:46:22 +00001377- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1378 imported into the module but exposed as part of the module's API.
1379
Brett Cannon7b96f072008-08-18 00:41:11 +00001380- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1381
Brett Cannon46225e72008-08-18 00:36:52 +00001382- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1383
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001384- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1385
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001386- Issue #3575: Incremental decoder's decode function now takes bytearray
1387 by using 's*' instead of 't#'.
1388
Jesus Cea585ad8a2009-07-02 15:37:21 +00001389- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001390 fails unicode conversion on 2nd parameter. (windows only)
1391
Facundo Batista94f243a2008-08-17 03:38:39 +00001392- Issue 2464. urllib2 now supports a malformation in the URL received
1393 in a redirect.
1394
Brett Cannonabe423e2008-08-16 21:47:07 +00001395- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001396 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001397
Facundo Batistaeb90b782008-08-16 14:44:07 +00001398- Issue #2776: fixed small issue when handling an URL with double slash
1399 after a 302 response in the case of not going through a proxy.
1400
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001401- Issue #2676: in the email package, content-type parsing was hanging on
1402 pathological input because of quadratic or exponential behaviour of a
1403 regular expression.
1404
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001405- Issue #3476: binary buffered reading through the new "io" library is now
1406 thread-safe.
1407
Brett Cannonbf3157b2008-08-14 05:00:03 +00001408- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1409 since mimetools itself is deprecated. Because modules are cached, all
1410 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1411
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001412- Issue #3134: shutil referenced undefined WindowsError symbol.
1413
Robert Schuppenies14646332008-08-10 11:01:53 +00001414- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1415 menu entries were not deleted.
1416
Brett Cannon83e81842008-08-09 23:30:55 +00001417- Copied the implementation of reduce() to _functools.reduce() to have a
1418 version that did not raise a DeprecationWarning under -3.
1419
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001420- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1421 a MemoryError rather than silently stop the iteration.
1422
Guido van Rossum59ce9012008-08-09 14:55:34 +00001423- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1424 to _sre.compile() will now be rejected. This should not affect anybody
1425 since the re.compile() function never generates invalid re-bytecode.
1426
Skip Montanaroa032bf42008-08-08 22:52:51 +00001427- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1428 upon first access it can be automatically initialized from the csv file if
1429 it wasn't initialized during instantiation.
1430
Brett Cannon3aa2a492008-08-06 22:28:09 +00001431- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1432 the reload() built-in has been removed.
1433
Brett Cannon7e30b672008-08-04 21:52:25 +00001434- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001435 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001436 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1437 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1438 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1439 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1440 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001441
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001442- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1443 raised an AttributeError.
1444
Benjamin Peterson01a24322008-07-28 23:35:27 +00001445- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001446 asking for a specific length. This problem only affected files opened
1447 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001448
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001449- Issue #3449: Update decimal module to use most recent specification
1450 (v. 1.68) and tests (v. 2.58) from IBM.
1451
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001452- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1453
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001454- Issue 1592: Improve error reporting when operations are attempted
1455 on a closed shelf.
1456

1458
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001459- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1460
1461- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1462 invalid arguments.
1463
1464- Issue #3302: Fix several crashes when calling locale's gettext functions
1465 with None arguments.
1466
1467- Issue #3389: Allow resolving dotted names for handlers in logging
1468 configuration files.
1469
1470- Deprecate the sunaudio module for removal in Python 3.0.
1471
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001472- Issue #3394: zipfile.writestr sets external attributes when passed a
1473 file name rather than a ZipInfo instance, so files are extracted with
1474 mode 0600 rather than 000 under Unix.
1475
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001476- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1477 argument in python 2.5, this broke code that subclassed Popen to include its
1478 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1486-------------
1487
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001488- Issue #2235: the C API function PyObject_HashNotImplemented and its
1489 interaction with the tp_hash slot (added in 2.6b2) are now documented
1490
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001491- Issue #643841: The language reference now provides more detailed
1492 coverage of the lookup process for special methods. The disclaimers
1493 regarding lack of coverage of new-style classes have also been
1494 removed, since the coverage is now fairly reasonable.

1503-----------------
1504
Georg Brandl3e483f62008-07-16 22:57:41 +00001505- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1506 its methods now allow for items objects that can be converted to
1507 an integer using operator.index().
1508
Mark Dickinson64b7e502008-07-16 09:40:03 +00001509- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1510 produced a ValueError instead of giving the correct float.
1511
Eric Smitha5fa5a22008-07-16 00:11:49 +00001512- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1513 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1514
Mark Dickinson7103aa42008-07-15 19:08:33 +00001515- Issue #3008: the float type has a new instance method 'float.hex'
1516 and a new class method 'float.fromhex' to convert floating-point
1517 numbers to and from hexadecimal strings, respectively.
1518
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001519- Issue #2235: __hash__ is once again inherited by default. To allow
1520 collections.Hashable to remain meaningful in the presence of the
1521 default hash implementation (object.__hash__), it is now possible
1522 to explicit block inheritance of hash by setting __hash__=None at
1523 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1524 level.
1525
Nick Coghlanb028f502008-07-13 14:52:36 +00001526- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1527 the parent module cannot be found while performing an absolute import.
1528 This means that an incorrectly defined __package__ attribute will
1529 now only prevent relative imports in that module rather than causing
1530 all imports from that module to fail.
1531
Nick Coghlan14ff9942008-07-08 14:21:42 +00001532- Issue #2517: Allow unicode messages in Exceptions again by correctly
1533 bypassing the instance dictionary when looking up __unicode__ on
1534 new-style classes.
1535
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001536- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1537 set to a custom object whose write() method happens to install
1538 another file in sys.stdout.
1539
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001540- Issue #3088: Corrected a race condition in classes derived from
1541 threading.local: the first member set by a thread could be saved in
1542 another thread's dictionary.
1543
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001544- Issue #3004: Minor change to slice.indices(): the start and stop
1545 arguments are now treated identically, making the behaviour easier
1546 to describe and understand. For example, slice(None, -10,
1547 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1548 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1549 10, -1).
1550
Georg Brandl278fc502008-07-19 12:46:12 +00001551- Issue #3219: Calling a function with repeated keyword arguments,
1552 f(a=2, a=23), would not cause a syntax error. This was a regression
1553 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001554
Georg Brandl278fc502008-07-19 12:46:12 +00001555- Issue #2862: Make int and float freelist management consistent with
1556 other freelists. Changes their CompactFreeList apis into
1557 ClearFreeList apis and calls them via gc.collect().

1560-------
1561
Thomas Heller57adf222008-08-14 19:10:48 +00001562- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1563 api functions without holding the GIL, which could lead to a fatal
1564 error when they failed.
1565
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001566- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001574- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1575 ForkingPickler.register() to resolve conflict with ctypes.
1576
Vinay Sajip51e65192008-07-18 09:01:10 +00001577- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001578
Thomas Heller880f5292008-07-15 19:39:38 +00001579- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1580 a valid dlerror() message.
1581
Thomas Heller2bad6572008-07-15 17:19:50 +00001582- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1583 incomplete structure was created.
1584
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001585- Issue #3339: dummy_thread.acquire() should not return None.
1586
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001587- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1588
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001589- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001590
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001591- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1592 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001593 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001594 content-length. The problem had been corrected in the 2.4 branch, but never

Georg Brandl5cc774e2008-06-11 20:28:06 +00002003 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002004
2005 This is controlled by the configure argument ``--with-universal-archs``:
2006
2007 - ``--with-universal-archs=all``: install 4-way universal
2008
2009 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2010
2011 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2012
2013 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002065- Issue #1631171: Re-implement the 'warnings' module in C (the
2066 original Python code has been kept as backup). This will allow for
2067 using the 'warning's machinery in such places as the parser where
2068 use of pure Python code is not possible. Both the ``showarning()``
2069 and ``formatwarning()`` gain an optional 'line' argument which is
2070 not called by default for backwards-compatibility reasons. Setting
2071 ``warnings.showwarning()`` to an implementation that lacks support
2072 for the ``line`` argument will raise a DeprecationWarning.

2096
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002097- The getpass module has been improved on Unix. It now uses /dev/tty
2098 by default and uses stderr instead of stdout. A GetPassWarning is
2099 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002114- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002115 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002135- Issue #2550: The approach used by client/server code for obtaining
2136 ports to listen on in network-oriented tests has been refined in an
2137 effort to facilitate running multiple instances of the entire
2138 regression test suite in parallel without issue.
2139 test_support.bind_port() has been fixed such that it will always
2140 return a unique port -- which wasn't always the case with the
2141 previous implementation, especially if socket options had been set
2142 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2143 new implementation of bind_port() will actually raise an exception
2144 if it is passed an AF_INET/SOCK_STREAM socket with either the
2145 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2146 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2147 the socket it's been passed. This currently only applies to
2148 Windows. This option prevents any other sockets from binding to the
2149 host/port we've bound to, thus removing the possibility of the
2150 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2151 when a second SOCK_STREAM socket binds and accepts to a host/port
2152 that's already been bound by another socket. The optional preferred
2153 port parameter to bind_port() has been removed. Under no
2154 circumstances should tests be hard coding ports!
2155
2156 test_support.find_unused_port() has also been introduced, which will
2157 pass a temporary socket object to bind_port() in order to obtain an
2158 unused port. The temporary socket object is then closed and
2159 deleted, and the port is returned. This method should only be used
2160 for obtaining an unused port in order to pass to an external program
2161 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2162 a parameter to a server-oriented class that doesn't give you direct
2163 access to the underlying socket used.
2164
2165 Finally, test_support.HOST has been introduced, which should be used
2166 for the host argument of any relevant socket calls (i.e. bind and
2167 connect).

2441Core and builtins
2442-----------------
2443
Fred Drakea8ee94b2008-03-01 02:45:07 +00002444- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002445 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002446
Georg Brandlad61bc82008-02-23 15:11:18 +00002447- Issue #2067: file.__exit__() now calls subclasses' close() method.
2448
2449- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002450
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002451- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002452 issue 215555 for a discussion.
2453
Eric Smitha73fbe72008-02-23 03:09:44 +00002454- Added the future_builtins module, which contains hex() and oct().
2455 These are the PEP 3127 version of these functions, designed to be
2456 compatible with the hex() and oct() builtins from Python 3.0. They
2457 differ slightly in their output formats from the existing, unchanged
2458 Python 2.6 builtins. The expected usage of the future_builtins
2459 module is:
2460 from future_builtins import hex, oct
2461
Eric Smith7ef40bf2008-02-20 23:34:22 +00002462- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2463 exponents for exponents with absolute value < 100. Follows C99
2464 standard. This is a change on Windows, which would use 3 digits.
2465 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2466 so that any alterations it does to the resulting string will be
2467 available in stringlib/formatter.h (for float.__format__).
2468
Eric Smith5a3c1352008-02-19 13:21:56 +00002469- Implemented PEP 3101, Advanced String Formatting. This adds a new
2470 builtin format(); a format() method for str and unicode; a
2471 __format__() method to object, str, unicode, int, long, float, and
2472 datetime; the class string.Formatter; and the C API
2473 PyObject_Format().
2474
Georg Brandl3ee81df2008-05-17 18:14:43 +00002475- Fixed several potential crashes, all caused by specially crafted
2476 __del__ methods exploiting objects in temporarily inconsistent
2477 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002478
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002479- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002480 prevent a possible crash: an Abstract Base Class would try to access
2481 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002482
Georg Brandl3ee81df2008-05-17 18:14:43 +00002483- Fixed repr() and str() of complex numbers with infinity or nan as
2484 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002485
Georg Brandl3ee81df2008-05-17 18:14:43 +00002486- Clear all free lists during a gc.collect() of the highest generation
2487 in order to allow pymalloc to free more arenas. Python may give back
2488 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002489
Georg Brandl3ee81df2008-05-17 18:14:43 +00002490- Issue #2045: Fix an infinite recursion triggered when printing a
2491 subclass of collections.defaultdict, if its default_factory is set
2492 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002493
Christian Heimesf75dbef2008-02-08 00:11:31 +00002494- Fixed a minor memory leak in dictobject.c. The content of the free
2495 list was not freed on interpreter shutdown.
2496
Georg Brandl3ee81df2008-05-17 18:14:43 +00002497- Limit free list of method and builtin function objects to 256
2498 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002499
Georg Brandl3ee81df2008-05-17 18:14:43 +00002500- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2501 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002502 to compact the internal free lists of pre-allocted ints and floats.
2503
Georg Brandl3ee81df2008-05-17 18:14:43 +00002504- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2505 calls. Python expected the return type int but the fork familie
2506 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002507
Georg Brandl3ee81df2008-05-17 18:14:43 +00002508- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2509 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002510
Georg Brandl3ee81df2008-05-17 18:14:43 +00002511- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2512 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002513
Georg Brandl3ee81df2008-05-17 18:14:43 +00002514- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2515 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002516
Georg Brandl3ee81df2008-05-17 18:14:43 +00002517- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2518 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002519
Georg Brandl3ee81df2008-05-17 18:14:43 +00002520- Patch #1473257: generator objects gain a gi_code attribute. This is
2521 the same object as the func_code attribute of the function that
2522 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002523
Georg Brandl3ee81df2008-05-17 18:14:43 +00002524- Issue #1920: "while 0" statements were completely removed by the
2525 compiler, even in the presence of an "else" clause, which is
2526 supposed to be run when the condition is false. Now the compiler
2527 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002528
Guido van Rossumeead05f2008-01-24 18:21:02 +00002529- A few crashers fixed: weakref_in_del.py (issue #1377858);
2530 loosing_dict_ref.py (issue #1303614, test67.py);
2531 borrowed_ref_[34].py (not in tracker).
2532
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002533- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002534 suppressed while an extension is loaded by calling SetErrorMode in
2535 dynload_win.c. The error is still reported properly.
2536
Georg Brandl3ee81df2008-05-17 18:14:43 +00002537- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002538 several extension methods and modules do not work without unicode
2539 support.
2540
Georg Brandl26543b12008-01-21 18:36:51 +00002541- Issue #1882: when compiling code from a string, encoding cookies in the
2542 second line of code were not always recognized correctly.
2543
Georg Brandl14404b62008-01-19 19:27:05 +00002544- Issue #1679: "0x" was taken as a valid integer literal.
2545
Georg Brandl6caad7d2008-01-26 14:19:22 +00002546- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002547 added.
2548
Christian Heimesc94e2b52008-01-14 04:13:37 +00002549- sys.float_info / PyFloat_GetInfo: The floating point information
2550 object was converted from a dict to a specialized structseq object.
2551
Georg Brandl3ee81df2008-05-17 18:14:43 +00002552- Patch #1816: Added sys.flags structseq. It exposes the status of
2553 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002554
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555- Objects/structseq.c: Implemented new structseq representation. The
2556 patch makes structseqs (e.g. the return value of os.stat) more
2557 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002558
Georg Brandl3ee81df2008-05-17 18:14:43 +00002559- Patch #1700288: added a type attribute cache that caches method
2560 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002561
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002562- Bug #1776: __import__() no longer accepts filenames on any platform.
2563 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002564
Georg Brandlaed6c662008-01-07 17:25:53 +00002565- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2566
Georg Brandl3ee81df2008-05-17 18:14:43 +00002567- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2568 envvar and sys.dont_write_bytecode attribute. All these can be set
2569 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002570
Georg Brandl3ee81df2008-05-17 18:14:43 +00002571- Improve some exception messages when Windows fails to load an
2572 extension module. Now we get for example '%1 is not a valid Win32
2573 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002574
Georg Brandl3ee81df2008-05-17 18:14:43 +00002575- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002577- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2578 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002579
Christian Heimes0a8143f2007-12-18 23:22:54 +00002580- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002581 and INF. float("nan"), float("inf") and float("-inf") now work on
2582 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002583
Georg Brandl3ee81df2008-05-17 18:14:43 +00002584- Compiler now generates simpler and faster code for dictionary
2585 literals. The oparg for BUILD_MAP now indicates an estimated
2586 dictionary size. There is a new opcode, STORE_MAP, for adding
2587 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002588
Georg Brandl3ee81df2008-05-17 18:14:43 +00002589- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002597- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002598 SystemError.
2599
Nick Coghlanef01d822007-12-03 12:55:17 +00002600- PEP 366: Allow explicit relative imports when executing modules
2601 inside packages with the -m switch via a new module level
2602 __package__ attribute.
2603
Georg Brandl3ee81df2008-05-17 18:14:43 +00002604- Issue #1402: Fix a crash on exit, when another thread is still
2605 running, and if the deallocation of its frames somehow calls the
2606 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002607

2617 file can now be directly executed by passing their name to the
2618 interpreter. The directory/zipfile is automatically inserted as the
2619 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002620
Georg Brandl3ee81df2008-05-17 18:14:43 +00002621- Issue #1265: Fix a problem with sys.settrace, if the tracing
2622 function uses a generator expression when at the same time the
2623 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002624
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002625- sets and frozensets now have an isdisjoint() method.
2626
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002627- optimize the performance of builtin.sum().
2628
Neal Norwitz44f326e2007-10-05 05:29:17 +00002629- Fix warnings found by the new version of the Coverity checker.
2630
Georg Brandl3ee81df2008-05-17 18:14:43 +00002631- The enumerate() builtin function is no longer bounded to sequences
2632 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2633 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002634
Georg Brandl3ee81df2008-05-17 18:14:43 +00002635- Issue #1686386: Tuple's tp_repr did not take into account the
2636 possibility of having a self-referential tuple, which is possible
2637 from C code. Nor did object's tp_str consider that a type's tp_str
2638 could do something that could lead to an inifinite recursion.
2639 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2640 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002641
Georg Brandl3ee81df2008-05-17 18:14:43 +00002642- Issue #1164: It was possible to trigger deadlock when using the
2643 'print' statement to write to a file since the GIL was not released
2644 as needed. Now PyObject_Print() does the right thing along with
2645 various tp_print implementations of the built-in types and those in
2646 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002647
Georg Brandl3ee81df2008-05-17 18:14:43 +00002648- Issue #1147: Exceptions were directly allowing string exceptions in
2649 their throw() method even though string exceptions no longer
2650 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002651
Georg Brandl3ee81df2008-05-17 18:14:43 +00002652- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002655- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002656 PyObject_Call() never calling back out to Python code to trigger
2657 recursion depth updates/checks. Required the creation of a static

Neal Norwitz0ac60192007-05-27 04:08:54 +00002675- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002676 __*__ attributes. (Some already existed, e.g., __doc__ and
2677 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002678
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002679- Add -3 option to the interpreter to warn about features that are

2684
Collin Winter62903052007-05-18 23:11:24 +00002685- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002686 "except E as target:". This is to provide forwards compatibility
2687 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002688
Brett Cannon229cee22007-05-05 01:34:02 +00002689- Deprecate BaseException.message as per PEP 352.
2690
Georg Brandl3ee81df2008-05-17 18:14:43 +00002691- Issue #1303614: don't expose object's __dict__ when the dict is

2693
Vinay Sajip8549ce32007-05-06 17:53:37 +00002694- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002695 setting a plain string, ie don't expand to single letter identifiers.
2696
Raymond Hettinger13936692007-04-11 18:40:58 +00002697- Request #1191699: Slices can now be pickled.
2698
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002699- Request #1193128: str.translate() now allows a None argument for

2707
Guido van Rossum143b5642007-03-23 04:58:42 +00002708- Bug #1683368: The object.__init__() and object.__new__() methods are
2709 now stricter in rejecting excess arguments. The only time when
2710 either allows excess arguments is when it is not overridden and the
2711 other one is. For backwards compatibility, when both are
2712 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002713 warning later). Also, type.__init__() insists on the same signature
2714 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002715
Georg Brandl3ee81df2008-05-17 18:14:43 +00002716- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2717 object to complex using its __complex__() method before falling back
2718 to the __float__() method. Therefore, the functions in the cmath
2719 module now can operate on objects that define a __complex__()
2720 method.

2737
Georg Brandl7b9c5552007-03-12 14:30:05 +00002738- Bug #1678647: write a newline after printing an exception in any
2739 case, even when converting the value to a string failed.
2740
Georg Brandl871f1bc2007-03-12 13:17:36 +00002741- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002742 its argument, if it exists. If not, it will work like before. This
2743 allows customizing the output of dir() in the presence of a
2744 __getattr__().

2754 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002755
Georg Brandlaa2321b2007-03-07 00:40:28 +00002756- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002757 makes the filenames the warning module prints much more sensible
2758 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002759

Georg Brandl0fca97a2007-03-05 22:28:08 +00002771- Patch #1674228: when assigning a slice (old-style), check for the
2772 sq_ass_slice instead of the sq_slice slot.
2773
Georg Brandl3ee81df2008-05-17 18:14:43 +00002774- When printing an unraisable error, don't print exceptions. before

3403 incompatibility since it never made sense with ordinary subclasses
3404 -- the failure just occurred later, with a more cumbersome
3405 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003686- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3687 with RFC 3207 and forgets any knowledge obtained from the server not
3688 obtained from the TLS negotiation itself. Patch contributed by Bill
3689 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003690
Georg Brandl3ee81df2008-05-17 18:14:43 +00003691- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003692 that the SMTP.starttls() caller no longer needs to call ehlo()
3693 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003694 does not claim to support starttls. Adds the
3695 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3776 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3777 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003794 time so that opening a database previously created with the DB_DUP
3795 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3796 opens. Specifically: dictionary assignment to a DB object will
3797 replace all values for a given key when the database allows
3798 duplicate values. DB users should use DB.put(k, v) when they want
3799 to store duplicates; not DB[k] = v.

3806 characters with ASCII value less than 32. Also, it correctly quotes
3807 dots only if they occur on a single line, as opposed to the previous
3808 behavior of quoting dots if they are the second character of any
3809 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004126- Makefile.pre.in(buildbottest): Run an optional script
4127 pybuildbot.identify to include some information about the build
4128 environment.

4132-----
4133
Georg Brandl3ee81df2008-05-17 18:14:43 +00004134- Unified naming convention for free lists and their limits. All free
4135 lists in Object/ are named ``free_list``, the counter ``numfree``
4136 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4137 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004138
Georg Brandl3ee81df2008-05-17 18:14:43 +00004139- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4140 to ``PyTuple_SetItem``, it can be used to populate a brand new
4141 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004142
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004143- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004144
Georg Brandl3ee81df2008-05-17 18:14:43 +00004145- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4146 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4147 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004148
4149- Patch #1720595: add T_BOOL to the range of structmember types.
4150
4151- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4152 ``PyFloat_GetInfo()`` to the float API.
4153
Georg Brandl3ee81df2008-05-17 18:14:43 +00004154- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4155 of w# format code incorrectly truncated the length to an int, even
4156 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4157 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4160 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004161
Georg Brandl3ee81df2008-05-17 18:14:43 +00004162- PEP 3123: Provide forward compatibility with Python 3.0, while
4163 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4164 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004165
Georg Brandl3ee81df2008-05-17 18:14:43 +00004166- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4167 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004168
4169- Patch #1733960: Allow T_LONGLONG to accept ints.
4170
4171- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4172
Christian Heimes000a0742008-01-03 22:16:32 +00004173- Added a new API function ``PyImport_ImportModuleNoBlock``.
4174
Georg Brandl6caad7d2008-01-26 14:19:22 +00004175- Bug #1637022: Prefix AST symbols with _Py_.
4176
4177- Fix some leftovers from the conversion from int to Py_ssize_t
4178 (relevant to strings and sequences of more than 2**31 items).
4179
4180- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4181 outside of pystate.c and should not be necessary.
4182
Georg Brandl3ee81df2008-05-17 18:14:43 +00004183- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4184 absolute imports. In earlier versions they might have used relative
4185 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004186
Georg Brandl3ee81df2008-05-17 18:14:43 +00004187- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4188 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4191 macro so it can be used as an expression.

4196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4198 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4199 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4200 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004201
Georg Brandl3ee81df2008-05-17 18:14:43 +00004202- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4203 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004215- Removed the macfs module. It had been deprecated since Python 2.5.
4216 This lead to the deprecation of macostools.touched() as it relied
4217 solely on macfs and was a no-op under OS X.
