Georg Brandld2094602008-12-05 08:51:30 +0000510 method on file objects with closefd=False. The file descriptor is still

881What's New in Python 2.6.1
882==========================
883
884*Release date: 04-Dec-2008*
885
886Core and Builtins
887-----------------
888
889- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
890 interpreter to abort ("Fatal Python error: Could not reset the stack!")
891 instead of throwing a MemoryError.
892
893- Issue #4367: Python would segfault during compiling when the unicodedata
894 module couldn't be imported and \N escapes were present.
895
896- Issue #4348: Some bytearray methods returned that didn't cause any change to
897 the bytearray, returned the same bytearray instead of a copy.
898
899- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
900
901- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
902
903- Issue #4048: The parser module now correctly validates relative imports.
904
905- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
906 exec statement.
907
908- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
909 method does not return iterators for the 4th and 5th items.
910
911- Issue #4209: Enabling unicode_literals and the print_function in the same
912 __future__ import didn't work.
913
914- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
915 returned a path longer than MAX_PATH. (But It's doubtful this code path is
916 really executed because I cannot move to such directory on win2k)
917
918- Issue #4069: When set.remove(element) is used with a set element, the element
919 is temporarily replaced with an equivalent frozenset. But the eventual
920 KeyError would always report the empty frozenset([]) as the missing key. Now
921 it correctly refers to the initial element.
922
923- Fixed C99 style comments in several files. Python is now C89 compatible
924 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001071- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1072
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001073- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1074 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1075 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1076 ``printf`` function, whereas PyString_FromFormat has an independent
1077 implementation and uses "%zd" on all platforms for size_t values.
1078 This makes a difference on win64, where ``printf`` needs "%Id" to display
1079 64bit values.
1080
Benjamin Peterson97179b02008-09-09 20:55:01 +00001081- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1082 error.
1083
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001084- Issue #3777: long() applied to a float object now always return a long
1085 object; previously an int would be returned for small values. the __long__
1086 method is allowed to return either an int or a long, but the behaviour of
1087 float objects should not change to respect backward compatibility.
1088
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001089- Issue #3751: str.rpartition would perform a left-partition when called with
1090 a unicode argument.
1091
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001092- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001094- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001095 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001096 was correctly parsed but parsing of subsequent arguments failed.
1097
Vinay Sajip35e3b032008-09-01 14:33:59 +00001098- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001099 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1100 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1101 when given a tuple of classes as second argument, were looking up
1102 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1103 type object.
1104
Neal Norwitz18aa3882008-08-24 05:04:52 +00001105- Fix crashes on memory allocation failure found with failmalloc.
1106
1107- Fix memory leaks found with valgrind and update suppressions file.
1108
1109- Fix compiler warnings in opt mode which would lead to invalid memory reads.

1114 function 'stringlib_contains_obj'.

1174 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1175 for catch_warnings() also led to an improvement in the raising of a
1176 DeprecationWarning related to warnings.warn_explicit().

1245-----------------
1246
Guido van Rossumf8402962008-08-20 15:01:50 +00001247- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1248 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1249 extensions do not automatically benefit from the class attribute
1250 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1251 to their tp_flags field if they care. This is a backwards
1252 compatibility feature; in 3.0, all types will use the cache by
1253 default.
1254
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001255- Keyword arguments can now follow starred arguments. (``f(a, *args,
1256 keyword=23)`` is now valid syntax.)
1257
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001258- ctypes function pointers that are COM methods have a boolean True
1259 value again.
1260
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001261- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1262 by denying s# to parse objects that have a releasebuffer procedure,
1263 and introducing s*.
1264
Georg Brandl1e13ea92008-08-11 09:07:59 +00001265- Issue #3537: Fix an assertion failure when an empty but presized dict
1266 object was stored in the freelist.
1267
Mark Dickinsonb6467572008-08-04 21:30:09 +00001268- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1269 ValueError consistently across platforms.
1270
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001271- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1272 (64bit Unix, for example), unichr() would truncate its argument and return
1273 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1274
Neal Norwitze7d8be82008-07-31 17:17:14 +00001275- Apply security patches from Apple.
1276
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001277- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1278 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1279
Antoine Pitrou92f82162008-07-25 22:22:08 +00001280- Issue #1819: function calls with several named parameters are now on
1281 average 35% faster (as measured by pybench).
1282
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001283- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1284 the python debugger steps into a class statement: the free variables (local
1285 variables defined in an outer scope) would be deleted from the outer scope.
1286
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001287- Issue #2620: Overflow checking when allocating or reallocating memory
1288 was not always being done properly in some python types and extension
1289 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1290 all been updated to perform better checks and places in the code that
1291 would previously leak memory on the error path when such an allocation
1292 failed have been fixed.

1298
Benjamin Petersone977ad42008-08-20 01:42:01 +00001299- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1300 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1301
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001302- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1303 version reported by these tools does not necessarily follow the python
1304 version numbering scheme, so the module is less strict when parsing it.
1305
Nick Coghlanf70385a2008-08-18 12:42:46 +00001306- Issue #2235: Added Py3k warnings for types which will become unhashable
1307 under the stricter __hash__ inheritance rules in 3.0. Several types
1308 which did not meet the rules for hash invariants and were already
1309 unhashable in 3.0 have now been explicitly flagged as unhashable in
1310 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1311 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1312
Brett Cannon88f801d2008-08-18 00:46:22 +00001313- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1342 thread-safe.
1343
Brett Cannonbf3157b2008-08-14 05:00:03 +00001344- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1345 since mimetools itself is deprecated. Because modules are cached, all
1346 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1347

1360 to _sre.compile() will now be rejected. This should not affect anybody
1361 since the re.compile() function never generates invalid re-bytecode.

1365 it wasn't initialized during instantiation.
1366
Brett Cannon3aa2a492008-08-06 22:28:09 +00001367- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1368 the reload() built-in has been removed.
1369

1379 raised an AttributeError.
1380
Benjamin Peterson01a24322008-07-28 23:35:27 +00001381- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001382 asking for a specific length. This problem only affected files opened
1383 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001384

1409 file name rather than a ZipInfo instance, so files are extracted with
1410 mode 0600 rather than 000 under Unix.
1411
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001412- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001424- Issue #2235: the C API function PyObject_HashNotImplemented and its
1425 interaction with the tp_hash slot (added in 2.6b2) are now documented
1426
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001427- Issue #643841: The language reference now provides more detailed
1428 coverage of the lookup process for special methods. The disclaimers
1429 regarding lack of coverage of new-style classes have also been

1434================================
1435
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001436*Release date: 17-Jul-2008*
1437
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001438Core and Builtins
1439-----------------
1440
Georg Brandl3e483f62008-07-16 22:57:41 +00001441- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1442 its methods now allow for items objects that can be converted to
1443 an integer using operator.index().
1444
Mark Dickinson64b7e502008-07-16 09:40:03 +00001445- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1446 produced a ValueError instead of giving the correct float.
1447
Eric Smitha5fa5a22008-07-16 00:11:49 +00001448- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1449 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1450
Mark Dickinson7103aa42008-07-15 19:08:33 +00001451- Issue #3008: the float type has a new instance method 'float.hex'
1452 and a new class method 'float.fromhex' to convert floating-point
1453 numbers to and from hexadecimal strings, respectively.
1454
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001455- Issue #2235: __hash__ is once again inherited by default. To allow
1456 collections.Hashable to remain meaningful in the presence of the
1457 default hash implementation (object.__hash__), it is now possible
1458 to explicit block inheritance of hash by setting __hash__=None at
1459 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1460 level.
1461
Nick Coghlanb028f502008-07-13 14:52:36 +00001462- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1463 the parent module cannot be found while performing an absolute import.
1464 This means that an incorrectly defined __package__ attribute will
1465 now only prevent relative imports in that module rather than causing
1466 all imports from that module to fail.
1467
Nick Coghlan14ff9942008-07-08 14:21:42 +00001468- Issue #2517: Allow unicode messages in Exceptions again by correctly
1469 bypassing the instance dictionary when looking up __unicode__ on
1470 new-style classes.
1471
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001472- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1473 set to a custom object whose write() method happens to install
1474 another file in sys.stdout.
1475
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001476- Issue #3088: Corrected a race condition in classes derived from
1477 threading.local: the first member set by a thread could be saved in
1478 another thread's dictionary.
1479
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001480- Issue #3004: Minor change to slice.indices(): the start and stop
1481 arguments are now treated identically, making the behaviour easier
1482 to describe and understand. For example, slice(None, -10,
1483 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1484 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1485 10, -1).
1486
Georg Brandl278fc502008-07-19 12:46:12 +00001487- Issue #3219: Calling a function with repeated keyword arguments,
1488 f(a=2, a=23), would not cause a syntax error. This was a regression
1489 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001490
Georg Brandl278fc502008-07-19 12:46:12 +00001491- Issue #2862: Make int and float freelist management consistent with
1492 other freelists. Changes their CompactFreeList apis into
1493 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001498- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1499 api functions without holding the GIL, which could lead to a fatal
1500 error when they failed.
1501
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001502- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1512
Vinay Sajip51e65192008-07-18 09:01:10 +00001513- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001527- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1528 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001529 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001530 content-length. The problem had been corrected in the 2.4 branch, but never
1531 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001546- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1547 handling is now the same as that of other special attributes like __name__).
1548
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001549- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00001939 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001940
1941 This is controlled by the configure argument ``--with-universal-archs``:
1942
1943 - ``--with-universal-archs=all``: install 4-way universal
1944
1945 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1946
1947 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1948
1949 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002001- Issue #1631171: Re-implement the 'warnings' module in C (the
2002 original Python code has been kept as backup). This will allow for
2003 using the 'warning's machinery in such places as the parser where
2004 use of pure Python code is not possible. Both the ``showarning()``
2005 and ``formatwarning()`` gain an optional 'line' argument which is
2006 not called by default for backwards-compatibility reasons. Setting
2007 ``warnings.showwarning()`` to an implementation that lacks support
2008 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002071- Issue #2550: The approach used by client/server code for obtaining
2072 ports to listen on in network-oriented tests has been refined in an
2073 effort to facilitate running multiple instances of the entire
2074 regression test suite in parallel without issue.
2075 test_support.bind_port() has been fixed such that it will always
2076 return a unique port -- which wasn't always the case with the
2077 previous implementation, especially if socket options had been set
2078 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2079 new implementation of bind_port() will actually raise an exception
2080 if it is passed an AF_INET/SOCK_STREAM socket with either the
2081 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2082 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2083 the socket it's been passed. This currently only applies to
2084 Windows. This option prevents any other sockets from binding to the
2085 host/port we've bound to, thus removing the possibility of the
2086 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2087 when a second SOCK_STREAM socket binds and accepts to a host/port
2088 that's already been bound by another socket. The optional preferred
2089 port parameter to bind_port() has been removed. Under no
2090 circumstances should tests be hard coding ports!
2091
2092 test_support.find_unused_port() has also been introduced, which will
2093 pass a temporary socket object to bind_port() in order to obtain an
2094 unused port. The temporary socket object is then closed and
2095 deleted, and the port is returned. This method should only be used
2096 for obtaining an unused port in order to pass to an external program
2097 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2098 a parameter to a server-oriented class that doesn't give you direct
2099 access to the underlying socket used.
2100
2101 Finally, test_support.HOST has been introduced, which should be used
2102 for the host argument of any relevant socket calls (i.e. bind and
2103 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002104
2105 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002106 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002107 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2108 test_asynchat and test_socket_ssl.
2109
Georg Brandl3ee81df2008-05-17 18:14:43 +00002110 It is now possible for multiple instances of the regression test
2111 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002165- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002166 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2167 Plane. This affected raw unicode literals and the
2168 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2169 this case, like normal unicode literals and the 'unicode-escape'
2170 codec.

2392 compatible with the hex() and oct() builtins from Python 3.0. They
2393 differ slightly in their output formats from the existing, unchanged
2394 Python 2.6 builtins. The expected usage of the future_builtins
2395 module is:
2396 from future_builtins import hex, oct

2399 exponents for exponents with absolute value < 100. Follows C99
2400 standard. This is a change on Windows, which would use 3 digits.
2401 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2402 so that any alterations it does to the resulting string will be
2403 available in stringlib/formatter.h (for float.__format__).
2404
Eric Smith5a3c1352008-02-19 13:21:56 +00002405- Implemented PEP 3101, Advanced String Formatting. This adds a new
2406 builtin format(); a format() method for str and unicode; a
2407 __format__() method to object, str, unicode, int, long, float, and
2408 datetime; the class string.Formatter; and the C API
2409 PyObject_Format().
2410
Georg Brandl3ee81df2008-05-17 18:14:43 +00002411- Fixed several potential crashes, all caused by specially crafted
2412 __del__ methods exploiting objects in temporarily inconsistent
2413 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002422- Clear all free lists during a gc.collect() of the highest generation
2423 in order to allow pymalloc to free more arenas. Python may give back
2424 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002425
Georg Brandl3ee81df2008-05-17 18:14:43 +00002426- Issue #2045: Fix an infinite recursion triggered when printing a
2427 subclass of collections.defaultdict, if its default_factory is set
2428 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00002430- Fixed a minor memory leak in dictobject.c. The content of the free
2431 list was not freed on interpreter shutdown.
2432
Georg Brandl3ee81df2008-05-17 18:14:43 +00002433- Limit free list of method and builtin function objects to 256
2434 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002435
Georg Brandl3ee81df2008-05-17 18:14:43 +00002436- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2437 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002438 to compact the internal free lists of pre-allocted ints and floats.
2439
Georg Brandl3ee81df2008-05-17 18:14:43 +00002440- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2441 calls. Python expected the return type int but the fork familie
2442 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002456- Patch #1473257: generator objects gain a gi_code attribute. This is
2457 the same object as the func_code attribute of the function that
2458 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002459
Georg Brandl3ee81df2008-05-17 18:14:43 +00002460- Issue #1920: "while 0" statements were completely removed by the
2461 compiler, even in the presence of an "else" clause, which is
2462 supposed to be run when the condition is false. Now the compiler
2463 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002464
Guido van Rossumeead05f2008-01-24 18:21:02 +00002465- A few crashers fixed: weakref_in_del.py (issue #1377858);
2466 loosing_dict_ref.py (issue #1303614, test67.py);
2467 borrowed_ref_[34].py (not in tracker).
2468
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002469- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002470 suppressed while an extension is loaded by calling SetErrorMode in
2471 dynload_win.c. The error is still reported properly.
2472
Georg Brandl3ee81df2008-05-17 18:14:43 +00002473- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002474 several extension methods and modules do not work without unicode
2475 support.
2476
Georg Brandl26543b12008-01-21 18:36:51 +00002477- Issue #1882: when compiling code from a string, encoding cookies in the
2478 second line of code were not always recognized correctly.
2479
Georg Brandl14404b62008-01-19 19:27:05 +00002480- Issue #1679: "0x" was taken as a valid integer literal.
2481
Georg Brandl6caad7d2008-01-26 14:19:22 +00002482- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002483 added.
2484
Christian Heimesc94e2b52008-01-14 04:13:37 +00002485- sys.float_info / PyFloat_GetInfo: The floating point information
2486 object was converted from a dict to a specialized structseq object.
2487
Georg Brandl3ee81df2008-05-17 18:14:43 +00002488- Patch #1816: Added sys.flags structseq. It exposes the status of
2489 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002490
Georg Brandl3ee81df2008-05-17 18:14:43 +00002491- Objects/structseq.c: Implemented new structseq representation. The
2492 patch makes structseqs (e.g. the return value of os.stat) more
2493 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002494
Georg Brandl3ee81df2008-05-17 18:14:43 +00002495- Patch #1700288: added a type attribute cache that caches method
2496 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002497
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002498- Bug #1776: __import__() no longer accepts filenames on any platform.
2499 The first parameter to __import__() must be a valid module name.

2504 envvar and sys.dont_write_bytecode attribute. All these can be set
2505 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002506
Georg Brandl3ee81df2008-05-17 18:14:43 +00002507- Improve some exception messages when Windows fails to load an
2508 extension module. Now we get for example '%1 is not a valid Win32
2509 application' instead of 'error code 193'.

2566
Georg Brandl3ee81df2008-05-17 18:14:43 +00002567- The enumerate() builtin function is no longer bounded to sequences
2568 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2569 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002570
Georg Brandl3ee81df2008-05-17 18:14:43 +00002571- Issue #1686386: Tuple's tp_repr did not take into account the
2572 possibility of having a self-referential tuple, which is possible
2573 from C code. Nor did object's tp_str consider that a type's tp_str
2574 could do something that could lead to an inifinite recursion.
2575 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2576 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002577

2579 'print' statement to write to a file since the GIL was not released
2580 as needed. Now PyObject_Print() does the right thing along with
2581 various tp_print implementations of the built-in types and those in
2582 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002592 PyObject_Call() never calling back out to Python code to trigger
2593 recursion depth updates/checks. Required the creation of a static
2594 RuntimeError instance in case normalizing an exception put the
2595 recursion check value past its limit. Fixes crashers

2643
Guido van Rossum143b5642007-03-23 04:58:42 +00002644- Bug #1683368: The object.__init__() and object.__new__() methods are
2645 now stricter in rejecting excess arguments. The only time when
2646 either allows excess arguments is when it is not overridden and the
2647 other one is. For backwards compatibility, when both are
2648 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002649 warning later). Also, type.__init__() insists on the same signature
2650 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002652- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2653 object to complex using its __complex__() method before falling back
2654 to the __float__() method. Therefore, the functions in the cmath
2655 module now can operate on objects that define a __complex__()
2656 method.

2667 its type.

2673
Georg Brandl7b9c5552007-03-12 14:30:05 +00002674- Bug #1678647: write a newline after printing an exception in any
2675 case, even when converting the value to a string failed.
2676
Georg Brandl871f1bc2007-03-12 13:17:36 +00002677- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002678 its argument, if it exists. If not, it will work like before. This
2679 allows customizing the output of dir() in the presence of a
2680 __getattr__().

2690 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002691
Georg Brandlaa2321b2007-03-07 00:40:28 +00002692- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002693 makes the filenames the warning module prints much more sensible
2694 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002695

Georg Brandl0fca97a2007-03-05 22:28:08 +00002707- Patch #1674228: when assigning a slice (old-style), check for the
2708 sq_ass_slice instead of the sq_slice slot.
2709
Georg Brandl3ee81df2008-05-17 18:14:43 +00002710- When printing an unraisable error, don't print exceptions. before
2711 the name. This duplicates the behavior whening normally printing
2712 exceptions.

2721 created a weakref on itself during a __del__ call for new-style
2722 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00002762- Bug #1545497: when given an explicit base, int() did ignore NULs
2763 embedded in the string to convert.
2764
Georg Brandl846f73a2006-10-08 07:11:54 +00002765- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002813 generator expressions (x for x, in ... ) works again. Fixing this
2814 problem required changing the .pyc magic number. This means that
2815 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003618- The implementation of UnicodeError objects has been simplified
3619 (start and end attributes are now stored directly as Py_ssize_t
3620 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003622- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3623 with RFC 3207 and forgets any knowledge obtained from the server not
3624 obtained from the TLS negotiation itself. Patch contributed by Bill
3625 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003626
Georg Brandl3ee81df2008-05-17 18:14:43 +00003627- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003628 that the SMTP.starttls() caller no longer needs to call ehlo()
3629 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003630 does not claim to support starttls. Adds the
3631 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3632 Fenner.

3712 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3713 silently miscode subclasses of those types. Now, it raises a
3714 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003715

Georg Brandl3ee81df2008-05-17 18:14:43 +00003730 time so that opening a database previously created with the DB_DUP
3731 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3732 opens. Specifically: dictionary assignment to a DB object will
3733 replace all values for a given key when the database allows
3734 duplicate values. DB users should use DB.put(k, v) when they want
3735 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003736

3742 characters with ASCII value less than 32. Also, it correctly quotes
3743 dots only if they occur on a single line, as opposed to the previous
3744 behavior of quoting dots if they are the second character of any
3745 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003746
