Jesse Nollerb48cfa62009-03-30 16:19:10 +0000648 socket.SO_REUSEADDR on all connections so that the user no longer needs
649 to wait 120 seconds for the socket to expire.
650

656 output compared to previous Python versions.
657
Lars Gustäbel9e2a09a2009-03-22 20:22:29 +0000658- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
659 forever on incomplete input. That caused tarfile.open() to hang when used
660 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
661 partial bzip2 compressed data.
662
Benjamin Peterson373498f2009-03-22 17:49:21 +0000663- Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to

Jesse Nollere6bab482009-03-30 16:11:16 +0000712- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks
Barry Warsaw90971e02009-04-07 01:54:02 +0000713 for *nix machines for negative handles and large int handles. Without this
714 check it is possible to segfault the interpreter.

751
Antoine Pitrou19fec8b2009-01-21 00:56:37 +0000752- Issue #5008: When a file is opened in append mode with the new IO library,
753 do an explicit seek to the end of file (so that e.g. tell() returns the
754 file size rather than 0). This is consistent with the behaviour of the
755 traditional 2.x file object.

789- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
790 302 conformant loader) will now work correctly in most cases (they
791 are still subject to the constraints that exist for all code running
792 from inside a module loaded via a PEP 302 loader and attempting to

951What's New in Python 2.6.1
952==========================
953
954*Release date: 04-Dec-2008*
955
956Core and Builtins
957-----------------
958
959- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
960 interpreter to abort ("Fatal Python error: Could not reset the stack!")
961 instead of throwing a MemoryError.
962
963- Issue #4367: Python would segfault during compiling when the unicodedata
964 module couldn't be imported and \N escapes were present.
965
966- Issue #4348: Some bytearray methods returned that didn't cause any change to
967 the bytearray, returned the same bytearray instead of a copy.
968
969- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
970
971- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
972
973- Issue #4048: The parser module now correctly validates relative imports.
974
975- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
976 exec statement.
977
978- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
979 method does not return iterators for the 4th and 5th items.
980
981- Issue #4209: Enabling unicode_literals and the print_function in the same
982 __future__ import didn't work.
983
984- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
985 returned a path longer than MAX_PATH. (But It's doubtful this code path is
986 really executed because I cannot move to such directory on win2k)
987
988- Issue #4069: When set.remove(element) is used with a set element, the element
989 is temporarily replaced with an equivalent frozenset. But the eventual
990 KeyError would always report the empty frozenset([]) as the missing key. Now
991 it correctly refers to the initial element.
992
993- Fixed C99 style comments in several files. Python is now C89 compatible
994 again.
995
996Library
997-------
998
Christian Heimes268be912008-11-28 11:03:48 +0000999- Issue #3741: DISTUTILS_USE_SDK set causes msvc9compiler.py to raise an

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001141- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1142
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001143- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1144 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1145 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1146 ``printf`` function, whereas PyString_FromFormat has an independent
1147 implementation and uses "%zd" on all platforms for size_t values.
1148 This makes a difference on win64, where ``printf`` needs "%Id" to display
1149 64bit values.

1155 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001166 was correctly parsed but parsing of subsequent arguments failed.
1167
Vinay Sajip35e3b032008-09-01 14:33:59 +00001168- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001169 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1170 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1171 when given a tuple of classes as second argument, were looking up
1172 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1173 type object.
1174

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001309What's New in Python 2.6 beta 3?
1310================================
1311
Barry Warsaw07a4a382008-08-21 01:15:08 +00001312*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001313
1314Core and Builtins
1315-----------------
1316
Guido van Rossumf8402962008-08-20 15:01:50 +00001317- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1318 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1319 extensions do not automatically benefit from the class attribute
1320 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1321 to their tp_flags field if they care. This is a backwards
1322 compatibility feature; in 3.0, all types will use the cache by
1323 default.
1324
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001325- Keyword arguments can now follow starred arguments. (``f(a, *args,
1326 keyword=23)`` is now valid syntax.)
1327
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001328- ctypes function pointers that are COM methods have a boolean True
1329 value again.
1330
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001331- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1332 by denying s# to parse objects that have a releasebuffer procedure,
1333 and introducing s*.
1334
Georg Brandl1e13ea92008-08-11 09:07:59 +00001335- Issue #3537: Fix an assertion failure when an empty but presized dict
1336 object was stored in the freelist.
1337
Mark Dickinsonb6467572008-08-04 21:30:09 +00001338- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1339 ValueError consistently across platforms.
1340
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001341- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1342 (64bit Unix, for example), unichr() would truncate its argument and return
1343 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1344
Neal Norwitze7d8be82008-07-31 17:17:14 +00001345- Apply security patches from Apple.
1346
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001347- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1348 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1349
Antoine Pitrou92f82162008-07-25 22:22:08 +00001350- Issue #1819: function calls with several named parameters are now on
1351 average 35% faster (as measured by pybench).
1352
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001353- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1354 the python debugger steps into a class statement: the free variables (local
1355 variables defined in an outer scope) would be deleted from the outer scope.
1356
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001357- Issue #2620: Overflow checking when allocating or reallocating memory
1358 was not always being done properly in some python types and extension
1359 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1360 all been updated to perform better checks and places in the code that
1361 would previously leak memory on the error path when such an allocation
1362 failed have been fixed.
1363
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001364Library
1365-------
1366
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001367- Issue #3612: Added some missing basic types in ctypes.wintypes.
1368
Benjamin Petersone977ad42008-08-20 01:42:01 +00001369- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1370 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1371
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001372- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1373 version reported by these tools does not necessarily follow the python
1374 version numbering scheme, so the module is less strict when parsing it.
1375
Nick Coghlanf70385a2008-08-18 12:42:46 +00001376- Issue #2235: Added Py3k warnings for types which will become unhashable
1377 under the stricter __hash__ inheritance rules in 3.0. Several types
1378 which did not meet the rules for hash invariants and were already
1379 unhashable in 3.0 have now been explicitly flagged as unhashable in
1380 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1381 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1382
Brett Cannon88f801d2008-08-18 00:46:22 +00001383- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1384 imported into the module but exposed as part of the module's API.
1385
Brett Cannon7b96f072008-08-18 00:41:11 +00001386- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1387
Brett Cannon46225e72008-08-18 00:36:52 +00001388- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1389
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001390- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1391
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001392- Issue #3575: Incremental decoder's decode function now takes bytearray
1393 by using 's*' instead of 't#'.
1394
Jesus Cea585ad8a2009-07-02 15:37:21 +00001395- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001396 fails unicode conversion on 2nd parameter. (windows only)
1397
Facundo Batista94f243a2008-08-17 03:38:39 +00001398- Issue 2464. urllib2 now supports a malformation in the URL received
1399 in a redirect.
1400
Brett Cannonabe423e2008-08-16 21:47:07 +00001401- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001402 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001403
Facundo Batistaeb90b782008-08-16 14:44:07 +00001404- Issue #2776: fixed small issue when handling an URL with double slash
1405 after a 302 response in the case of not going through a proxy.
1406
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001407- Issue #2676: in the email package, content-type parsing was hanging on
1408 pathological input because of quadratic or exponential behaviour of a
1409 regular expression.
1410
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001411- Issue #3476: binary buffered reading through the new "io" library is now
1412 thread-safe.
1413
Brett Cannonbf3157b2008-08-14 05:00:03 +00001414- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1415 since mimetools itself is deprecated. Because modules are cached, all
1416 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1417
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001418- Issue #3134: shutil referenced undefined WindowsError symbol.
1419
Robert Schuppenies14646332008-08-10 11:01:53 +00001420- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1421 menu entries were not deleted.
1422
Brett Cannon83e81842008-08-09 23:30:55 +00001423- Copied the implementation of reduce() to _functools.reduce() to have a
1424 version that did not raise a DeprecationWarning under -3.
1425
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001426- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1427 a MemoryError rather than silently stop the iteration.
1428
Guido van Rossum59ce9012008-08-09 14:55:34 +00001429- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1430 to _sre.compile() will now be rejected. This should not affect anybody
1431 since the re.compile() function never generates invalid re-bytecode.
1432
Skip Montanaroa032bf42008-08-08 22:52:51 +00001433- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1434 upon first access it can be automatically initialized from the csv file if
1435 it wasn't initialized during instantiation.
1436
Brett Cannon3aa2a492008-08-06 22:28:09 +00001437- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1438 the reload() built-in has been removed.
1439
Brett Cannon7e30b672008-08-04 21:52:25 +00001440- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001441 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001442 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,

1444 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1445 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1446 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001447
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001448- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1449 raised an AttributeError.
1450
Benjamin Peterson01a24322008-07-28 23:35:27 +00001451- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001452 asking for a specific length. This problem only affected files opened
1453 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001454
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001455- Issue #3449: Update decimal module to use most recent specification
1456 (v. 1.68) and tests (v. 2.58) from IBM.
1457
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001458- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

1464
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001465- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1466
1467- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1468 invalid arguments.
1469
1470- Issue #3302: Fix several crashes when calling locale's gettext functions
1471 with None arguments.
1472
1473- Issue #3389: Allow resolving dotted names for handlers in logging
1474 configuration files.
1475
1476- Deprecate the sunaudio module for removal in Python 3.0.
1477
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001478- Issue #3394: zipfile.writestr sets external attributes when passed a
1479 file name rather than a ZipInfo instance, so files are extracted with
1480 mode 0600 rather than 000 under Unix.
1481
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001482- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1483 argument in python 2.5, this broke code that subclassed Popen to include its
1484 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1492-------------
1493
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001494- Issue #2235: the C API function PyObject_HashNotImplemented and its
1495 interaction with the tp_hash slot (added in 2.6b2) are now documented
1496
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001497- Issue #643841: The language reference now provides more detailed
1498 coverage of the lookup process for special methods. The disclaimers
1499 regarding lack of coverage of new-style classes have also been
1500 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001503What's New in Python 2.6 beta 2?
1504================================
1505
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001506*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001508Core and Builtins
1509-----------------
1510
Georg Brandl3e483f62008-07-16 22:57:41 +00001511- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1512 its methods now allow for items objects that can be converted to
1513 an integer using operator.index().
1514
Mark Dickinson64b7e502008-07-16 09:40:03 +00001515- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1516 produced a ValueError instead of giving the correct float.
1517
Eric Smitha5fa5a22008-07-16 00:11:49 +00001518- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1519 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1520
Mark Dickinson7103aa42008-07-15 19:08:33 +00001521- Issue #3008: the float type has a new instance method 'float.hex'
1522 and a new class method 'float.fromhex' to convert floating-point
1523 numbers to and from hexadecimal strings, respectively.
1524
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001525- Issue #2235: __hash__ is once again inherited by default. To allow
1526 collections.Hashable to remain meaningful in the presence of the
1527 default hash implementation (object.__hash__), it is now possible
1528 to explicit block inheritance of hash by setting __hash__=None at
1529 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1530 level.
1531
Nick Coghlanb028f502008-07-13 14:52:36 +00001532- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1533 the parent module cannot be found while performing an absolute import.
1534 This means that an incorrectly defined __package__ attribute will
1535 now only prevent relative imports in that module rather than causing
1536 all imports from that module to fail.
1537
Nick Coghlan14ff9942008-07-08 14:21:42 +00001538- Issue #2517: Allow unicode messages in Exceptions again by correctly
1539 bypassing the instance dictionary when looking up __unicode__ on
1540 new-style classes.
1541
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001542- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1543 set to a custom object whose write() method happens to install
1544 another file in sys.stdout.
1545
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001546- Issue #3088: Corrected a race condition in classes derived from
1547 threading.local: the first member set by a thread could be saved in
1548 another thread's dictionary.
1549
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001550- Issue #3004: Minor change to slice.indices(): the start and stop
1551 arguments are now treated identically, making the behaviour easier
1552 to describe and understand. For example, slice(None, -10,
1553 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1554 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1555 10, -1).
1556
Georg Brandl278fc502008-07-19 12:46:12 +00001557- Issue #3219: Calling a function with repeated keyword arguments,
1558 f(a=2, a=23), would not cause a syntax error. This was a regression
1559 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001560
Georg Brandl278fc502008-07-19 12:46:12 +00001561- Issue #2862: Make int and float freelist management consistent with
1562 other freelists. Changes their CompactFreeList apis into
1563 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001568- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1569 api functions without holding the GIL, which could lead to a fatal
1570 error when they failed.
1571
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001572- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001580- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1581 ForkingPickler.register() to resolve conflict with ctypes.
1582
Vinay Sajip51e65192008-07-18 09:01:10 +00001583- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller2bad6572008-07-15 17:19:50 +00001588- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1589 incomplete structure was created.
1590
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001591- Issue #3339: dummy_thread.acquire() should not return None.
1592

Georg Brandl3ee81df2008-05-17 18:14:43 +00002071- Issue #1631171: Re-implement the 'warnings' module in C (the
2072 original Python code has been kept as backup). This will allow for
2073 using the 'warning's machinery in such places as the parser where
2074 use of pure Python code is not possible. Both the ``showarning()``
2075 and ``formatwarning()`` gain an optional 'line' argument which is
2076 not called by default for backwards-compatibility reasons. Setting
2077 ``warnings.showwarning()`` to an implementation that lacks support
2078 for the ``line`` argument will raise a DeprecationWarning.

2102
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002103- The getpass module has been improved on Unix. It now uses /dev/tty
2104 by default and uses stderr instead of stdout. A GetPassWarning is
2105 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002106

Georg Brandl3ee81df2008-05-17 18:14:43 +00002120- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002121 extension modules between 32 and 64 bit platforms. See the distutls

2143 effort to facilitate running multiple instances of the entire
2144 regression test suite in parallel without issue.
2145 test_support.bind_port() has been fixed such that it will always
2146 return a unique port -- which wasn't always the case with the
2147 previous implementation, especially if socket options had been set
2148 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2149 new implementation of bind_port() will actually raise an exception
2150 if it is passed an AF_INET/SOCK_STREAM socket with either the
2151 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2152 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2153 the socket it's been passed. This currently only applies to
2154 Windows. This option prevents any other sockets from binding to the
2155 host/port we've bound to, thus removing the possibility of the
2156 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2157 when a second SOCK_STREAM socket binds and accepts to a host/port
2158 that's already been bound by another socket. The optional preferred
2159 port parameter to bind_port() has been removed. Under no
2160 circumstances should tests be hard coding ports!
2161
2162 test_support.find_unused_port() has also been introduced, which will
2163 pass a temporary socket object to bind_port() in order to obtain an
2164 unused port. The temporary socket object is then closed and
2165 deleted, and the port is returned. This method should only be used
2166 for obtaining an unused port in order to pass to an external program
2167 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2168 a parameter to a server-oriented class that doesn't give you direct
2169 access to the underlying socket used.
2170
2171 Finally, test_support.HOST has been introduced, which should be used
2172 for the host argument of any relevant socket calls (i.e. bind and
2173 connect).

2175 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002176 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

2178 test_asynchat and test_socket_ssl.
2179
Georg Brandl3ee81df2008-05-17 18:14:43 +00002180 It is now possible for multiple instances of the regression test
2181 suite to run in parallel without issue.

2447Core and builtins
2448-----------------
2449
Fred Drakea8ee94b2008-03-01 02:45:07 +00002450- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002451 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002452
Georg Brandlad61bc82008-02-23 15:11:18 +00002453- Issue #2067: file.__exit__() now calls subclasses' close() method.
2454
2455- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002456
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002457- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002458 issue 215555 for a discussion.
2459
Eric Smitha73fbe72008-02-23 03:09:44 +00002460- Added the future_builtins module, which contains hex() and oct().
2461 These are the PEP 3127 version of these functions, designed to be
2462 compatible with the hex() and oct() builtins from Python 3.0. They
2463 differ slightly in their output formats from the existing, unchanged
2464 Python 2.6 builtins. The expected usage of the future_builtins
2465 module is:
2466 from future_builtins import hex, oct
2467
Eric Smith7ef40bf2008-02-20 23:34:22 +00002468- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2469 exponents for exponents with absolute value < 100. Follows C99
2470 standard. This is a change on Windows, which would use 3 digits.
2471 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2472 so that any alterations it does to the resulting string will be
2473 available in stringlib/formatter.h (for float.__format__).
2474
Eric Smith5a3c1352008-02-19 13:21:56 +00002475- Implemented PEP 3101, Advanced String Formatting. This adds a new
2476 builtin format(); a format() method for str and unicode; a
2477 __format__() method to object, str, unicode, int, long, float, and
2478 datetime; the class string.Formatter; and the C API
2479 PyObject_Format().
2480
Georg Brandl3ee81df2008-05-17 18:14:43 +00002481- Fixed several potential crashes, all caused by specially crafted
2482 __del__ methods exploiting objects in temporarily inconsistent
2483 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002484
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002485- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002486 prevent a possible crash: an Abstract Base Class would try to access
2487 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002488
Georg Brandl3ee81df2008-05-17 18:14:43 +00002489- Fixed repr() and str() of complex numbers with infinity or nan as
2490 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002491
Georg Brandl3ee81df2008-05-17 18:14:43 +00002492- Clear all free lists during a gc.collect() of the highest generation
2493 in order to allow pymalloc to free more arenas. Python may give back
2494 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002495
Georg Brandl3ee81df2008-05-17 18:14:43 +00002496- Issue #2045: Fix an infinite recursion triggered when printing a
2497 subclass of collections.defaultdict, if its default_factory is set
2498 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002499
Christian Heimesf75dbef2008-02-08 00:11:31 +00002500- Fixed a minor memory leak in dictobject.c. The content of the free
2501 list was not freed on interpreter shutdown.
2502
Georg Brandl3ee81df2008-05-17 18:14:43 +00002503- Limit free list of method and builtin function objects to 256
2504 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002505
Georg Brandl3ee81df2008-05-17 18:14:43 +00002506- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2507 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002508 to compact the internal free lists of pre-allocted ints and floats.
2509
Georg Brandl3ee81df2008-05-17 18:14:43 +00002510- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2511 calls. Python expected the return type int but the fork familie
2512 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002513
Georg Brandl3ee81df2008-05-17 18:14:43 +00002514- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2515 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002516
Georg Brandl3ee81df2008-05-17 18:14:43 +00002517- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2518 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002519
Georg Brandl3ee81df2008-05-17 18:14:43 +00002520- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2521 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002522
Georg Brandl3ee81df2008-05-17 18:14:43 +00002523- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2524 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002525
Georg Brandl3ee81df2008-05-17 18:14:43 +00002526- Patch #1473257: generator objects gain a gi_code attribute. This is
2527 the same object as the func_code attribute of the function that
2528 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002529
Georg Brandl3ee81df2008-05-17 18:14:43 +00002530- Issue #1920: "while 0" statements were completely removed by the
2531 compiler, even in the presence of an "else" clause, which is
2532 supposed to be run when the condition is false. Now the compiler
2533 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002534
Guido van Rossumeead05f2008-01-24 18:21:02 +00002535- A few crashers fixed: weakref_in_del.py (issue #1377858);
2536 loosing_dict_ref.py (issue #1303614, test67.py);
2537 borrowed_ref_[34].py (not in tracker).
2538
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002539- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002540 suppressed while an extension is loaded by calling SetErrorMode in
2541 dynload_win.c. The error is still reported properly.
2542
Georg Brandl3ee81df2008-05-17 18:14:43 +00002543- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002544 several extension methods and modules do not work without unicode
2545 support.
2546
Georg Brandl26543b12008-01-21 18:36:51 +00002547- Issue #1882: when compiling code from a string, encoding cookies in the
2548 second line of code were not always recognized correctly.
2549
Georg Brandl14404b62008-01-19 19:27:05 +00002550- Issue #1679: "0x" was taken as a valid integer literal.
2551
Georg Brandl6caad7d2008-01-26 14:19:22 +00002552- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002553 added.
2554
Christian Heimesc94e2b52008-01-14 04:13:37 +00002555- sys.float_info / PyFloat_GetInfo: The floating point information
2556 object was converted from a dict to a specialized structseq object.
2557
Georg Brandl3ee81df2008-05-17 18:14:43 +00002558- Patch #1816: Added sys.flags structseq. It exposes the status of
2559 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002560
Georg Brandl3ee81df2008-05-17 18:14:43 +00002561- Objects/structseq.c: Implemented new structseq representation. The
2562 patch makes structseqs (e.g. the return value of os.stat) more
2563 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002564
Georg Brandl3ee81df2008-05-17 18:14:43 +00002565- Patch #1700288: added a type attribute cache that caches method
2566 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002567
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002568- Bug #1776: __import__() no longer accepts filenames on any platform.
2569 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002570
Georg Brandlaed6c662008-01-07 17:25:53 +00002571- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2572
Georg Brandl3ee81df2008-05-17 18:14:43 +00002573- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2574 envvar and sys.dont_write_bytecode attribute. All these can be set
2575 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002576
Georg Brandl3ee81df2008-05-17 18:14:43 +00002577- Improve some exception messages when Windows fails to load an
2578 extension module. Now we get for example '%1 is not a valid Win32
2579 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002580
Georg Brandl3ee81df2008-05-17 18:14:43 +00002581- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002583- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2584 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002585
Christian Heimes0a8143f2007-12-18 23:22:54 +00002586- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002587 and INF. float("nan"), float("inf") and float("-inf") now work on
2588 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002589
Georg Brandl3ee81df2008-05-17 18:14:43 +00002590- Compiler now generates simpler and faster code for dictionary
2591 literals. The oparg for BUILD_MAP now indicates an estimated
2592 dictionary size. There is a new opcode, STORE_MAP, for adding
2593 entries to the dictionary.

2608 __package__ attribute.
2609
Georg Brandl3ee81df2008-05-17 18:14:43 +00002610- Issue #1402: Fix a crash on exit, when another thread is still
2611 running, and if the deallocation of its frames somehow calls the
2612 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002613

2623 file can now be directly executed by passing their name to the
2624 interpreter. The directory/zipfile is automatically inserted as the
2625 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002626
Georg Brandl3ee81df2008-05-17 18:14:43 +00002627- Issue #1265: Fix a problem with sys.settrace, if the tracing
2628 function uses a generator expression when at the same time the
2629 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002630
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002631- sets and frozensets now have an isdisjoint() method.
2632
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002633- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00002635- Fix warnings found by the new version of the Coverity checker.
2636
Georg Brandl3ee81df2008-05-17 18:14:43 +00002637- The enumerate() builtin function is no longer bounded to sequences
2638 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2639 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002640
Georg Brandl3ee81df2008-05-17 18:14:43 +00002641- Issue #1686386: Tuple's tp_repr did not take into account the
2642 possibility of having a self-referential tuple, which is possible
2643 from C code. Nor did object's tp_str consider that a type's tp_str
2644 could do something that could lead to an inifinite recursion.
2645 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2646 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002647
Georg Brandl3ee81df2008-05-17 18:14:43 +00002648- Issue #1164: It was possible to trigger deadlock when using the
2649 'print' statement to write to a file since the GIL was not released
2650 as needed. Now PyObject_Print() does the right thing along with
2651 various tp_print implementations of the built-in types and those in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002654- Issue #1147: Exceptions were directly allowing string exceptions in
2655 their throw() method even though string exceptions no longer
2656 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002657
Georg Brandl3ee81df2008-05-17 18:14:43 +00002658- Issue #1096: Prevent a segfault from getting the repr of a very
2659 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002660
Brett Cannon1e534b52007-09-07 04:18:30 +00002661- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002662 PyObject_Call() never calling back out to Python code to trigger
2663 recursion depth updates/checks. Required the creation of a static
2664 RuntimeError instance in case normalizing an exception put the
2665 recursion check value past its limit. Fixes crashers
2666 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002667

Neal Norwitz0ac60192007-05-27 04:08:54 +00002681- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002682 __*__ attributes. (Some already existed, e.g., __doc__ and
2683 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002684
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002685- Add -3 option to the interpreter to warn about features that are

2689 calls.
2690
Collin Winter62903052007-05-18 23:11:24 +00002691- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002692 "except E as target:". This is to provide forwards compatibility
2693 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002694
Brett Cannon229cee22007-05-05 01:34:02 +00002695- Deprecate BaseException.message as per PEP 352.
2696
Georg Brandl3ee81df2008-05-17 18:14:43 +00002697- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002698 inherited from a builtin base.
2699
Vinay Sajip8549ce32007-05-06 17:53:37 +00002700- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002701 setting a plain string, ie don't expand to single letter identifiers.
2702
Raymond Hettinger13936692007-04-11 18:40:58 +00002703- Request #1191699: Slices can now be pickled.
2704
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002705- Request #1193128: str.translate() now allows a None argument for
2706 translations that only remove characters without re-mapping the
2707 remaining characters.
2708
Georg Brandl5cb76c12007-03-21 09:00:39 +00002709- Patch #1682205: a TypeError while unpacking an iterable is no longer
2710 masked by a generic one with the message "unpack non-sequence".
2711
Neal Norwitzaa754b72007-03-21 06:39:48 +00002712- Remove unused file Python/fmod.c.
2713
Guido van Rossum143b5642007-03-23 04:58:42 +00002714- Bug #1683368: The object.__init__() and object.__new__() methods are
2715 now stricter in rejecting excess arguments. The only time when
2716 either allows excess arguments is when it is not overridden and the
2717 other one is. For backwards compatibility, when both are
2718 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002719 warning later). Also, type.__init__() insists on the same signature
2720 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002721
Georg Brandl3ee81df2008-05-17 18:14:43 +00002722- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2723 object to complex using its __complex__() method before falling back
2724 to the __float__() method. Therefore, the functions in the cmath
2725 module now can operate on objects that define a __complex__()
2726 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002727
Georg Brandl3ee81df2008-05-17 18:14:43 +00002728- Patch #1623563: allow __class__ assignment for classes with
2729 __slots__. The old and the new class are still required to have the
2730 same slot names.

2737 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002738
Georg Brandl3ee81df2008-05-17 18:14:43 +00002739- Patch #1680015: Don't modify __slots__ tuple if it contains an

2743
Georg Brandl7b9c5552007-03-12 14:30:05 +00002744- Bug #1678647: write a newline after printing an exception in any
2745 case, even when converting the value to a string failed.
2746
Georg Brandl871f1bc2007-03-12 13:17:36 +00002747- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002748 its argument, if it exists. If not, it will work like before. This
2749 allows customizing the output of dir() in the presence of a
2750 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002751
Collin Winter276887b2007-03-12 16:11:39 +00002752- Patch #922167: Python no longer segfaults when faced with infinitely
2753 self-recursive reload() calls (as reported by bug #742342).
2754

2759 parthensized forms. This means complex(repr(x)) now works instead of
2760 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002761
Georg Brandlaa2321b2007-03-07 00:40:28 +00002762- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002763 makes the filenames the warning module prints much more sensible
2764 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002765
Georg Brandl49aafc92007-03-07 00:34:46 +00002766- Variant of patch #697613: don't exit the interpreter on a SystemExit
2767 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002768 variable is given, but break into the interactive interpreter just
2769 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002777- Patch #1674228: when assigning a slice (old-style), check for the
2778 sq_ass_slice instead of the sq_slice slot.
2779
Georg Brandl3ee81df2008-05-17 18:14:43 +00002780- When printing an unraisable error, don't print exceptions. before
2781 the name. This duplicates the behavior whening normally printing
2782 exceptions.

2791 created a weakref on itself during a __del__ call for new-style
2792 classes (classic classes still have the bug).

Thomas Heller2456a3c2007-03-09 20:39:22 +00003390- Bug #1651235: When a tuple was passed to a ctypes function call,
3391 Python would crash instead of raising an error.
3392
Thomas Hellerc2f77252007-03-09 19:21:28 +00003393- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
3394 returned string up to the first NUL character.

3405
Georg Brandl3ee81df2008-05-17 18:14:43 +00003406- unittest now verifies more of its assumptions. In particular,
3407 TestCase and TestSuite subclasses (not instances) are no longer
3408 accepted in TestSuite.addTest(). This should cause no
3409 incompatibility since it never made sense with ordinary subclasses
3410 -- the failure just occurred later, with a more cumbersome
3411 exception.

Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003696
Georg Brandl3ee81df2008-05-17 18:14:43 +00003697- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003698 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00003700 does not claim to support starttls. Adds the

Georg Brandl3ee81df2008-05-17 18:14:43 +00003800 time so that opening a database previously created with the DB_DUP
3801 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3802 opens. Specifically: dictionary assignment to a DB object will
3803 replace all values for a given key when the database allows
3804 duplicate values. DB users should use DB.put(k, v) when they want
3805 to store duplicates; not DB[k] = v.

3812 characters with ASCII value less than 32. Also, it correctly quotes
3813 dots only if they occur on a single line, as opposed to the previous
3814 behavior of quoting dots if they are the second character of any
3815 line.

4138-----
4139
Georg Brandl3ee81df2008-05-17 18:14:43 +00004140- Unified naming convention for free lists and their limits. All free
4141 lists in Object/ are named ``free_list``, the counter ``numfree``
4142 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4143 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004144
Georg Brandl3ee81df2008-05-17 18:14:43 +00004145- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4146 to ``PyTuple_SetItem``, it can be used to populate a brand new
4147 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004148
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004149- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004151- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4152 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4153 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004154
4155- Patch #1720595: add T_BOOL to the range of structmember types.
4156
4157- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4158 ``PyFloat_GetInfo()`` to the float API.
4159
Georg Brandl3ee81df2008-05-17 18:14:43 +00004160- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4161 of w# format code incorrectly truncated the length to an int, even
4162 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4163 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004164
Georg Brandl3ee81df2008-05-17 18:14:43 +00004165- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4166 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004168- PEP 3123: Provide forward compatibility with Python 3.0, while
4169 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4170 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004171
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4173 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004174
4175- Patch #1733960: Allow T_LONGLONG to accept ints.

4182
4183- Fix some leftovers from the conversion from int to Py_ssize_t
4184 (relevant to strings and sequences of more than 2**31 items).
4185
4186- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4187 outside of pystate.c and should not be necessary.
4188
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4190 absolute imports. In earlier versions they might have used relative
4191 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4194 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004195
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4197 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004203- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4204 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4205 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4206 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004207
Georg Brandl3ee81df2008-05-17 18:14:43 +00004208- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004221- Removed the macfs module. It had been deprecated since Python 2.5.
4222 This lead to the deprecation of macostools.touched() as it relied
4223 solely on macfs and was a no-op under OS X.
