Georg Brandld2094602008-12-05 08:51:30 +0000512 method on file objects with closefd=False. The file descriptor is still

722 302 conformant loader) will now work correctly in most cases (they
723 are still subject to the constraints that exist for all code running

883What's New in Python 2.6.1
884==========================
885
886*Release date: 04-Dec-2008*
887
888Core and Builtins
889-----------------
890
891- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
892 interpreter to abort ("Fatal Python error: Could not reset the stack!")
893 instead of throwing a MemoryError.
894
895- Issue #4367: Python would segfault during compiling when the unicodedata
896 module couldn't be imported and \N escapes were present.
897
898- Issue #4348: Some bytearray methods returned that didn't cause any change to
899 the bytearray, returned the same bytearray instead of a copy.
900
901- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
902
903- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
904
905- Issue #4048: The parser module now correctly validates relative imports.
906
907- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
908 exec statement.
909
910- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
911 method does not return iterators for the 4th and 5th items.
912
913- Issue #4209: Enabling unicode_literals and the print_function in the same
914 __future__ import didn't work.
915
916- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
917 returned a path longer than MAX_PATH. (But It's doubtful this code path is
918 really executed because I cannot move to such directory on win2k)
919
920- Issue #4069: When set.remove(element) is used with a set element, the element
921 is temporarily replaced with an equivalent frozenset. But the eventual
922 KeyError would always report the empty frozenset([]) as the missing key. Now
923 it correctly refers to the initial element.
924
925- Fixed C99 style comments in several files. Python is now C89 compatible
926 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001073- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1074
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001075- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1076 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1077 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1078 ``printf`` function, whereas PyString_FromFormat has an independent
1079 implementation and uses "%zd" on all platforms for size_t values.
1080 This makes a difference on win64, where ``printf`` needs "%Id" to display
1081 64bit values.
1082
Benjamin Peterson97179b02008-09-09 20:55:01 +00001083- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1087 object; previously an int would be returned for small values. the __long__
1088 method is allowed to return either an int or a long, but the behaviour of
1089 float objects should not change to respect backward compatibility.
1090
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001091- Issue #3751: str.rpartition would perform a left-partition when called with
1092 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001097 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001098 was correctly parsed but parsing of subsequent arguments failed.
1099
Vinay Sajip35e3b032008-09-01 14:33:59 +00001100- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001101 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1102 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1103 when given a tuple of classes as second argument, were looking up
1104 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1105 type object.
1106
Neal Norwitz18aa3882008-08-24 05:04:52 +00001107- Fix crashes on memory allocation failure found with failmalloc.

1177 for catch_warnings() also led to an improvement in the raising of a

1247-----------------
1248
Guido van Rossumf8402962008-08-20 15:01:50 +00001249- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1250 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1251 extensions do not automatically benefit from the class attribute
1252 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1253 to their tp_flags field if they care. This is a backwards
1254 compatibility feature; in 3.0, all types will use the cache by
1255 default.
1256
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001257- Keyword arguments can now follow starred arguments. (``f(a, *args,
1258 keyword=23)`` is now valid syntax.)
1259
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001260- ctypes function pointers that are COM methods have a boolean True
1261 value again.
1262
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001263- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1264 by denying s# to parse objects that have a releasebuffer procedure,
1265 and introducing s*.
1266
Georg Brandl1e13ea92008-08-11 09:07:59 +00001267- Issue #3537: Fix an assertion failure when an empty but presized dict
1268 object was stored in the freelist.
1269
Mark Dickinsonb6467572008-08-04 21:30:09 +00001270- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1271 ValueError consistently across platforms.
1272
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001273- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1274 (64bit Unix, for example), unichr() would truncate its argument and return
1275 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1276
Neal Norwitze7d8be82008-07-31 17:17:14 +00001277- Apply security patches from Apple.
1278
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001279- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1280 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1281
Antoine Pitrou92f82162008-07-25 22:22:08 +00001282- Issue #1819: function calls with several named parameters are now on
1283 average 35% faster (as measured by pybench).
1284
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001285- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1286 the python debugger steps into a class statement: the free variables (local
1287 variables defined in an outer scope) would be deleted from the outer scope.
1288
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001289- Issue #2620: Overflow checking when allocating or reallocating memory
1290 was not always being done properly in some python types and extension
1291 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1292 all been updated to perform better checks and places in the code that
1293 would previously leak memory on the error path when such an allocation
1294 failed have been fixed.

Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001304- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1305 version reported by these tools does not necessarily follow the python
1306 version numbering scheme, so the module is less strict when parsing it.
1307
Nick Coghlanf70385a2008-08-18 12:42:46 +00001308- Issue #2235: Added Py3k warnings for types which will become unhashable
1309 under the stricter __hash__ inheritance rules in 3.0. Several types
1310 which did not meet the rules for hash invariants and were already
1311 unhashable in 3.0 have now been explicitly flagged as unhashable in
1312 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1313 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1314
Brett Cannon88f801d2008-08-18 00:46:22 +00001315- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1325 by using 's*' instead of 't#'.
1326
Jesus Cea585ad8a2009-07-02 15:37:21 +00001327- Issue #2222: Fixed reference leak when occurred os.rename()

1341 regular expression.
1342

1344 thread-safe.
1345
Brett Cannonbf3157b2008-08-14 05:00:03 +00001346- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1347 since mimetools itself is deprecated. Because modules are cached, all
1348 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1349
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001350- Issue #3134: shutil referenced undefined WindowsError symbol.

1356 version that did not raise a DeprecationWarning under -3.
1357

1362 to _sre.compile() will now be rejected. This should not affect anybody
1363 since the re.compile() function never generates invalid re-bytecode.
1364
Skip Montanaroa032bf42008-08-08 22:52:51 +00001365- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1366 upon first access it can be automatically initialized from the csv file if
1367 it wasn't initialized during instantiation.
1368
Brett Cannon3aa2a492008-08-06 22:28:09 +00001369- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1370 the reload() built-in has been removed.
1371
Brett Cannon7e30b672008-08-04 21:52:25 +00001372- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001373 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1381 raised an AttributeError.
1382
Benjamin Peterson01a24322008-07-28 23:35:27 +00001383- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001384 asking for a specific length. This problem only affected files opened
1385 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001386

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001410- Issue #3394: zipfile.writestr sets external attributes when passed a
1411 file name rather than a ZipInfo instance, so files are extracted with
1412 mode 0600 rather than 000 under Unix.
1413
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001414- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1427 interaction with the tp_hash slot (added in 2.6b2) are now documented
1428
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001429- Issue #643841: The language reference now provides more detailed
1430 coverage of the lookup process for special methods. The disclaimers
1431 regarding lack of coverage of new-style classes have also been
1432 removed, since the coverage is now fairly reasonable.

1436================================
1437
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001438*Release date: 17-Jul-2008*
1439
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001440Core and Builtins
1441-----------------
1442
Georg Brandl3e483f62008-07-16 22:57:41 +00001443- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1444 its methods now allow for items objects that can be converted to
1445 an integer using operator.index().
1446
Mark Dickinson64b7e502008-07-16 09:40:03 +00001447- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1448 produced a ValueError instead of giving the correct float.
1449
Eric Smitha5fa5a22008-07-16 00:11:49 +00001450- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1451 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1452
Mark Dickinson7103aa42008-07-15 19:08:33 +00001453- Issue #3008: the float type has a new instance method 'float.hex'
1454 and a new class method 'float.fromhex' to convert floating-point
1455 numbers to and from hexadecimal strings, respectively.
1456
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001457- Issue #2235: __hash__ is once again inherited by default. To allow
1458 collections.Hashable to remain meaningful in the presence of the
1459 default hash implementation (object.__hash__), it is now possible
1460 to explicit block inheritance of hash by setting __hash__=None at
1461 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1462 level.
1463
Nick Coghlanb028f502008-07-13 14:52:36 +00001464- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1465 the parent module cannot be found while performing an absolute import.
1466 This means that an incorrectly defined __package__ attribute will
1467 now only prevent relative imports in that module rather than causing
1468 all imports from that module to fail.
1469
Nick Coghlan14ff9942008-07-08 14:21:42 +00001470- Issue #2517: Allow unicode messages in Exceptions again by correctly
1471 bypassing the instance dictionary when looking up __unicode__ on
1472 new-style classes.
1473
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001474- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1475 set to a custom object whose write() method happens to install
1476 another file in sys.stdout.
1477
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001478- Issue #3088: Corrected a race condition in classes derived from
1479 threading.local: the first member set by a thread could be saved in
1480 another thread's dictionary.
1481
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001482- Issue #3004: Minor change to slice.indices(): the start and stop
1483 arguments are now treated identically, making the behaviour easier
1484 to describe and understand. For example, slice(None, -10,
1485 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1486 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1487 10, -1).
1488
Georg Brandl278fc502008-07-19 12:46:12 +00001489- Issue #3219: Calling a function with repeated keyword arguments,
1490 f(a=2, a=23), would not cause a syntax error. This was a regression
1491 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001492
Georg Brandl278fc502008-07-19 12:46:12 +00001493- Issue #2862: Make int and float freelist management consistent with
1494 other freelists. Changes their CompactFreeList apis into
1495 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001496

1498-------
1499
Thomas Heller57adf222008-08-14 19:10:48 +00001500- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1501 api functions without holding the GIL, which could lead to a fatal
1502 error when they failed.
1503
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001504- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1513 ForkingPickler.register() to resolve conflict with ctypes.
1514
Vinay Sajip51e65192008-07-18 09:01:10 +00001515- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

1518 a valid dlerror() message.
1519
Thomas Heller2bad6572008-07-15 17:19:50 +00001520- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1521 incomplete structure was created.
1522

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001527- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001528
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001529- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1530 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001531 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001532 content-length. The problem had been corrected in the 2.4 branch, but never
1533 merged into trunk.
1534

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001548- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1549 handling is now the same as that of other special attributes like __name__).
1550
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001551- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00001941 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001942
1943 This is controlled by the configure argument ``--with-universal-archs``:
1944
1945 - ``--with-universal-archs=all``: install 4-way universal
1946
1947 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1948
1949 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1950
1951 This option should be used in combination with ``--enable-universalsdk=``.
1952
1953 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002003- Issue #1631171: Re-implement the 'warnings' module in C (the
2004 original Python code has been kept as backup). This will allow for
2005 using the 'warning's machinery in such places as the parser where
2006 use of pure Python code is not possible. Both the ``showarning()``
2007 and ``formatwarning()`` gain an optional 'line' argument which is
2008 not called by default for backwards-compatibility reasons. Setting
2009 ``warnings.showwarning()`` to an implementation that lacks support
2010 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002073- Issue #2550: The approach used by client/server code for obtaining
2074 ports to listen on in network-oriented tests has been refined in an
2075 effort to facilitate running multiple instances of the entire
2076 regression test suite in parallel without issue.
2077 test_support.bind_port() has been fixed such that it will always
2078 return a unique port -- which wasn't always the case with the
2079 previous implementation, especially if socket options had been set
2080 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2081 new implementation of bind_port() will actually raise an exception
2082 if it is passed an AF_INET/SOCK_STREAM socket with either the
2083 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2084 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2085 the socket it's been passed. This currently only applies to
2086 Windows. This option prevents any other sockets from binding to the
2087 host/port we've bound to, thus removing the possibility of the
2088 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2089 when a second SOCK_STREAM socket binds and accepts to a host/port
2090 that's already been bound by another socket. The optional preferred
2091 port parameter to bind_port() has been removed. Under no
2092 circumstances should tests be hard coding ports!
2093
2094 test_support.find_unused_port() has also been introduced, which will
2095 pass a temporary socket object to bind_port() in order to obtain an
2096 unused port. The temporary socket object is then closed and
2097 deleted, and the port is returned. This method should only be used
2098 for obtaining an unused port in order to pass to an external program
2099 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2100 a parameter to a server-oriented class that doesn't give you direct
2101 access to the underlying socket used.
2102
2103 Finally, test_support.HOST has been introduced, which should be used
2104 for the host argument of any relevant socket calls (i.e. bind and
2105 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002106
2107 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002108 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002109 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2110 test_asynchat and test_socket_ssl.
2111
Georg Brandl3ee81df2008-05-17 18:14:43 +00002112 It is now possible for multiple instances of the regression test
2113 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002167- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002168 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2169 Plane. This affected raw unicode literals and the
2170 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2171 this case, like normal unicode literals and the 'unicode-escape'
2172 codec.

2391
Eric Smitha73fbe72008-02-23 03:09:44 +00002392- Added the future_builtins module, which contains hex() and oct().
2393 These are the PEP 3127 version of these functions, designed to be
2394 compatible with the hex() and oct() builtins from Python 3.0. They
2395 differ slightly in their output formats from the existing, unchanged
2396 Python 2.6 builtins. The expected usage of the future_builtins
2397 module is:

Eric Smith7ef40bf2008-02-20 23:34:22 +00002400- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2401 exponents for exponents with absolute value < 100. Follows C99
2402 standard. This is a change on Windows, which would use 3 digits.
2403 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2404 so that any alterations it does to the resulting string will be
2405 available in stringlib/formatter.h (for float.__format__).
2406
Eric Smith5a3c1352008-02-19 13:21:56 +00002407- Implemented PEP 3101, Advanced String Formatting. This adds a new
2408 builtin format(); a format() method for str and unicode; a
2409 __format__() method to object, str, unicode, int, long, float, and
2410 datetime; the class string.Formatter; and the C API
2411 PyObject_Format().
2412
Georg Brandl3ee81df2008-05-17 18:14:43 +00002413- Fixed several potential crashes, all caused by specially crafted
2414 __del__ methods exploiting objects in temporarily inconsistent
2415 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002424- Clear all free lists during a gc.collect() of the highest generation
2425 in order to allow pymalloc to free more arenas. Python may give back
2426 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002427
Georg Brandl3ee81df2008-05-17 18:14:43 +00002428- Issue #2045: Fix an infinite recursion triggered when printing a
2429 subclass of collections.defaultdict, if its default_factory is set
2430 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00002432- Fixed a minor memory leak in dictobject.c. The content of the free
2433 list was not freed on interpreter shutdown.
2434
Georg Brandl3ee81df2008-05-17 18:14:43 +00002435- Limit free list of method and builtin function objects to 256
2436 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002437
Georg Brandl3ee81df2008-05-17 18:14:43 +00002438- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2439 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002440 to compact the internal free lists of pre-allocted ints and floats.
2441
Georg Brandl3ee81df2008-05-17 18:14:43 +00002442- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2443 calls. Python expected the return type int but the fork familie
2444 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002445
Georg Brandl3ee81df2008-05-17 18:14:43 +00002446- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002458- Patch #1473257: generator objects gain a gi_code attribute. This is
2459 the same object as the func_code attribute of the function that
2460 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002461
Georg Brandl3ee81df2008-05-17 18:14:43 +00002462- Issue #1920: "while 0" statements were completely removed by the
2463 compiler, even in the presence of an "else" clause, which is
2464 supposed to be run when the condition is false. Now the compiler
2465 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002466
Guido van Rossumeead05f2008-01-24 18:21:02 +00002467- A few crashers fixed: weakref_in_del.py (issue #1377858);
2468 loosing_dict_ref.py (issue #1303614, test67.py);
2469 borrowed_ref_[34].py (not in tracker).
2470
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002471- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002472 suppressed while an extension is loaded by calling SetErrorMode in
2473 dynload_win.c. The error is still reported properly.
2474
Georg Brandl3ee81df2008-05-17 18:14:43 +00002475- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002476 several extension methods and modules do not work without unicode
2477 support.
2478
Georg Brandl26543b12008-01-21 18:36:51 +00002479- Issue #1882: when compiling code from a string, encoding cookies in the
2480 second line of code were not always recognized correctly.
2481
Georg Brandl14404b62008-01-19 19:27:05 +00002482- Issue #1679: "0x" was taken as a valid integer literal.
2483
Georg Brandl6caad7d2008-01-26 14:19:22 +00002484- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002485 added.
2486
Christian Heimesc94e2b52008-01-14 04:13:37 +00002487- sys.float_info / PyFloat_GetInfo: The floating point information
2488 object was converted from a dict to a specialized structseq object.
2489
Georg Brandl3ee81df2008-05-17 18:14:43 +00002490- Patch #1816: Added sys.flags structseq. It exposes the status of
2491 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002492
Georg Brandl3ee81df2008-05-17 18:14:43 +00002493- Objects/structseq.c: Implemented new structseq representation. The
2494 patch makes structseqs (e.g. the return value of os.stat) more
2495 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002496
Georg Brandl3ee81df2008-05-17 18:14:43 +00002497- Patch #1700288: added a type attribute cache that caches method
2498 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002499
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002500- Bug #1776: __import__() no longer accepts filenames on any platform.
2501 The first parameter to __import__() must be a valid module name.

2506 envvar and sys.dont_write_bytecode attribute. All these can be set
2507 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002508
Georg Brandl3ee81df2008-05-17 18:14:43 +00002509- Improve some exception messages when Windows fails to load an
2510 extension module. Now we get for example '%1 is not a valid Win32
2511 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002512

2568
Georg Brandl3ee81df2008-05-17 18:14:43 +00002569- The enumerate() builtin function is no longer bounded to sequences
2570 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2571 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002572
Georg Brandl3ee81df2008-05-17 18:14:43 +00002573- Issue #1686386: Tuple's tp_repr did not take into account the
2574 possibility of having a self-referential tuple, which is possible
2575 from C code. Nor did object's tp_str consider that a type's tp_str
2576 could do something that could lead to an inifinite recursion.
2577 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2578 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002579
Georg Brandl3ee81df2008-05-17 18:14:43 +00002580- Issue #1164: It was possible to trigger deadlock when using the
2581 'print' statement to write to a file since the GIL was not released
2582 as needed. Now PyObject_Print() does the right thing along with
2583 various tp_print implementations of the built-in types and those in
2584 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002585
Georg Brandl3ee81df2008-05-17 18:14:43 +00002586- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002594 PyObject_Call() never calling back out to Python code to trigger
2595 recursion depth updates/checks. Required the creation of a static
2596 RuntimeError instance in case normalizing an exception put the
2597 recursion check value past its limit. Fixes crashers

2645
Guido van Rossum143b5642007-03-23 04:58:42 +00002646- Bug #1683368: The object.__init__() and object.__new__() methods are
2647 now stricter in rejecting excess arguments. The only time when
2648 either allows excess arguments is when it is not overridden and the
2649 other one is. For backwards compatibility, when both are
2650 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002651 warning later). Also, type.__init__() insists on the same signature
2652 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002654- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2655 object to complex using its __complex__() method before falling back
2656 to the __float__() method. Therefore, the functions in the cmath
2657 module now can operate on objects that define a __complex__()
2658 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00002676- Bug #1678647: write a newline after printing an exception in any
2677 case, even when converting the value to a string failed.
2678
Georg Brandl871f1bc2007-03-12 13:17:36 +00002679- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002680 its argument, if it exists. If not, it will work like before. This
2681 allows customizing the output of dir() in the presence of a
2682 __getattr__().

2692 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00002694- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002695 makes the filenames the warning module prints much more sensible
2696 when a PYTHONSTARTUP file is used.

2711
Georg Brandl3ee81df2008-05-17 18:14:43 +00002712- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00002764- Bug #1545497: when given an explicit base, int() did ignore NULs
2765 embedded in the string to convert.
2766
Georg Brandl846f73a2006-10-08 07:11:54 +00002767- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002815 generator expressions (x for x, in ... ) works again. Fixing this
2816 problem required changing the .pyc magic number. This means that

Georg Brandl3ee81df2008-05-17 18:14:43 +00003620- The implementation of UnicodeError objects has been simplified
3621 (start and end attributes are now stored directly as Py_ssize_t
3622 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003624- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3625 with RFC 3207 and forgets any knowledge obtained from the server not
3626 obtained from the TLS negotiation itself. Patch contributed by Bill
3627 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003628
Georg Brandl3ee81df2008-05-17 18:14:43 +00003629- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003630 that the SMTP.starttls() caller no longer needs to call ehlo()
3631 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003632 does not claim to support starttls. Adds the
3633 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3634 Fenner.

3714 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3715 silently miscode subclasses of those types. Now, it raises a
3716 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003717

Georg Brandl3ee81df2008-05-17 18:14:43 +00003732 time so that opening a database previously created with the DB_DUP
3733 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3734 opens. Specifically: dictionary assignment to a DB object will
3735 replace all values for a given key when the database allows
3736 duplicate values. DB users should use DB.put(k, v) when they want
3737 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003738

3744 characters with ASCII value less than 32. Also, it correctly quotes
3745 dots only if they occur on a single line, as opposed to the previous
3746 behavior of quoting dots if they are the second character of any
3747 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003748
