Georg Brandld2094602008-12-05 08:51:30 +0000507 method on file objects with closefd=False. The file descriptor is still

878What's New in Python 2.6.1
879==========================
880
881*Release date: 04-Dec-2008*
882
883Core and Builtins
884-----------------
885
886- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
887 interpreter to abort ("Fatal Python error: Could not reset the stack!")
888 instead of throwing a MemoryError.
889
890- Issue #4367: Python would segfault during compiling when the unicodedata
891 module couldn't be imported and \N escapes were present.
892
893- Issue #4348: Some bytearray methods returned that didn't cause any change to
894 the bytearray, returned the same bytearray instead of a copy.
895
896- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
897
898- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
899
900- Issue #4048: The parser module now correctly validates relative imports.
901
902- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
903 exec statement.
904
905- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
906 method does not return iterators for the 4th and 5th items.
907
908- Issue #4209: Enabling unicode_literals and the print_function in the same
909 __future__ import didn't work.
910
911- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
912 returned a path longer than MAX_PATH. (But It's doubtful this code path is
913 really executed because I cannot move to such directory on win2k)
914
915- Issue #4069: When set.remove(element) is used with a set element, the element
916 is temporarily replaced with an equivalent frozenset. But the eventual
917 KeyError would always report the empty frozenset([]) as the missing key. Now
918 it correctly refers to the initial element.
919
920- Fixed C99 style comments in several files. Python is now C89 compatible
921 again.

1067
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001068- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1069
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001070- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1071 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1072 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1073 ``printf`` function, whereas PyString_FromFormat has an independent
1074 implementation and uses "%zd" on all platforms for size_t values.
1075 This makes a difference on win64, where ``printf`` needs "%Id" to display
1076 64bit values.
1077
Benjamin Peterson97179b02008-09-09 20:55:01 +00001078- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1079 error.
1080
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001081- Issue #3777: long() applied to a float object now always return a long
1082 object; previously an int would be returned for small values. the __long__
1083 method is allowed to return either an int or a long, but the behaviour of
1084 float objects should not change to respect backward compatibility.
1085
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001086- Issue #3751: str.rpartition would perform a left-partition when called with
1087 a unicode argument.
1088
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001089- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001091- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001092 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001093 was correctly parsed but parsing of subsequent arguments failed.
1094
Vinay Sajip35e3b032008-09-01 14:33:59 +00001095- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001096 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1097 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1098 when given a tuple of classes as second argument, were looking up
1099 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1100 type object.
1101
Neal Norwitz18aa3882008-08-24 05:04:52 +00001102- Fix crashes on memory allocation failure found with failmalloc.
1103
1104- Fix memory leaks found with valgrind and update suppressions file.
1105
1106- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Nick Coghland2e09382008-09-11 12:11:06 +00001144- Issue #3781: Clean up the API for warnings.catch_warnings() by having it

1171 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1172 for catch_warnings() also led to an improvement in the raising of a
1173 DeprecationWarning related to warnings.warn_explicit().

1241Core and Builtins
1242-----------------
1243
Guido van Rossumf8402962008-08-20 15:01:50 +00001244- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1245 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1246 extensions do not automatically benefit from the class attribute
1247 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1248 to their tp_flags field if they care. This is a backwards
1249 compatibility feature; in 3.0, all types will use the cache by
1250 default.
1251
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001252- Keyword arguments can now follow starred arguments. (``f(a, *args,
1253 keyword=23)`` is now valid syntax.)
1254
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001255- ctypes function pointers that are COM methods have a boolean True
1256 value again.
1257
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001258- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1259 by denying s# to parse objects that have a releasebuffer procedure,
1260 and introducing s*.
1261
Georg Brandl1e13ea92008-08-11 09:07:59 +00001262- Issue #3537: Fix an assertion failure when an empty but presized dict
1263 object was stored in the freelist.
1264
Mark Dickinsonb6467572008-08-04 21:30:09 +00001265- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1266 ValueError consistently across platforms.
1267
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001268- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1269 (64bit Unix, for example), unichr() would truncate its argument and return
1270 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1271
Neal Norwitze7d8be82008-07-31 17:17:14 +00001272- Apply security patches from Apple.
1273
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001274- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1275 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1276
Antoine Pitrou92f82162008-07-25 22:22:08 +00001277- Issue #1819: function calls with several named parameters are now on
1278 average 35% faster (as measured by pybench).
1279
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001280- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1281 the python debugger steps into a class statement: the free variables (local
1282 variables defined in an outer scope) would be deleted from the outer scope.
1283
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001284- Issue #2620: Overflow checking when allocating or reallocating memory
1285 was not always being done properly in some python types and extension
1286 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1287 all been updated to perform better checks and places in the code that
1288 would previously leak memory on the error path when such an allocation
1289 failed have been fixed.

1295
Benjamin Petersone977ad42008-08-20 01:42:01 +00001296- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1297 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1298
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001299- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1300 version reported by these tools does not necessarily follow the python
1301 version numbering scheme, so the module is less strict when parsing it.
1302
Nick Coghlanf70385a2008-08-18 12:42:46 +00001303- Issue #2235: Added Py3k warnings for types which will become unhashable
1304 under the stricter __hash__ inheritance rules in 3.0. Several types

Antoine Pitroude781a42008-08-09 12:43:23 +00001379 asking for a specific length. This problem only affected files opened

1407 mode 0600 rather than 000 under Unix.
1408
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001409- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1422 interaction with the tp_hash slot (added in 2.6b2) are now documented
1423
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001424- Issue #643841: The language reference now provides more detailed

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001433*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001435Core and Builtins
1436-----------------
1437
Georg Brandl3e483f62008-07-16 22:57:41 +00001438- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1439 its methods now allow for items objects that can be converted to
1440 an integer using operator.index().
1441
Mark Dickinson64b7e502008-07-16 09:40:03 +00001442- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1443 produced a ValueError instead of giving the correct float.
1444
Eric Smitha5fa5a22008-07-16 00:11:49 +00001445- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1446 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1447
Mark Dickinson7103aa42008-07-15 19:08:33 +00001448- Issue #3008: the float type has a new instance method 'float.hex'
1449 and a new class method 'float.fromhex' to convert floating-point
1450 numbers to and from hexadecimal strings, respectively.
1451
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001452- Issue #2235: __hash__ is once again inherited by default. To allow
1453 collections.Hashable to remain meaningful in the presence of the
1454 default hash implementation (object.__hash__), it is now possible
1455 to explicit block inheritance of hash by setting __hash__=None at
1456 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1457 level.
1458
Nick Coghlanb028f502008-07-13 14:52:36 +00001459- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1460 the parent module cannot be found while performing an absolute import.
1461 This means that an incorrectly defined __package__ attribute will
1462 now only prevent relative imports in that module rather than causing
1463 all imports from that module to fail.
1464
Nick Coghlan14ff9942008-07-08 14:21:42 +00001465- Issue #2517: Allow unicode messages in Exceptions again by correctly
1466 bypassing the instance dictionary when looking up __unicode__ on
1467 new-style classes.
1468

1470 set to a custom object whose write() method happens to install
1471 another file in sys.stdout.
1472
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001473- Issue #3088: Corrected a race condition in classes derived from
1474 threading.local: the first member set by a thread could be saved in
1475 another thread's dictionary.
1476
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001477- Issue #3004: Minor change to slice.indices(): the start and stop
1478 arguments are now treated identically, making the behaviour easier
1479 to describe and understand. For example, slice(None, -10,
1480 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1481 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1482 10, -1).
1483
Georg Brandl278fc502008-07-19 12:46:12 +00001484- Issue #3219: Calling a function with repeated keyword arguments,
1485 f(a=2, a=23), would not cause a syntax error. This was a regression
1486 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001487
Georg Brandl278fc502008-07-19 12:46:12 +00001488- Issue #2862: Make int and float freelist management consistent with
1489 other freelists. Changes their CompactFreeList apis into

1496 api functions without holding the GIL, which could lead to a fatal
1497 error when they failed.
1498
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001499- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001524- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1525 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001526 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001527 content-length. The problem had been corrected in the 2.4 branch, but never
1528 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001543- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1935 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001936 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001937
1938 This is controlled by the configure argument ``--with-universal-archs``:
1939
1940 - ``--with-universal-archs=all``: install 4-way universal
1941
1942 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1943
1944 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1945
1946 This option should be used in combination with ``--enable-universalsdk=``.
1947
1948 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 +00001998- Issue #1631171: Re-implement the 'warnings' module in C (the
1999 original Python code has been kept as backup). This will allow for
2000 using the 'warning's machinery in such places as the parser where
2001 use of pure Python code is not possible. Both the ``showarning()``
2002 and ``formatwarning()`` gain an optional 'line' argument which is
2003 not called by default for backwards-compatibility reasons. Setting
2004 ``warnings.showwarning()`` to an implementation that lacks support
2005 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002068- Issue #2550: The approach used by client/server code for obtaining
2069 ports to listen on in network-oriented tests has been refined in an
2070 effort to facilitate running multiple instances of the entire
2071 regression test suite in parallel without issue.
2072 test_support.bind_port() has been fixed such that it will always
2073 return a unique port -- which wasn't always the case with the
2074 previous implementation, especially if socket options had been set
2075 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2076 new implementation of bind_port() will actually raise an exception
2077 if it is passed an AF_INET/SOCK_STREAM socket with either the
2078 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2079 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2080 the socket it's been passed. This currently only applies to
2081 Windows. This option prevents any other sockets from binding to the
2082 host/port we've bound to, thus removing the possibility of the
2083 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2084 when a second SOCK_STREAM socket binds and accepts to a host/port
2085 that's already been bound by another socket. The optional preferred
2086 port parameter to bind_port() has been removed. Under no
2087 circumstances should tests be hard coding ports!
2088
2089 test_support.find_unused_port() has also been introduced, which will
2090 pass a temporary socket object to bind_port() in order to obtain an
2091 unused port. The temporary socket object is then closed and
2092 deleted, and the port is returned. This method should only be used
2093 for obtaining an unused port in order to pass to an external program
2094 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2095 a parameter to a server-oriented class that doesn't give you direct
2096 access to the underlying socket used.
2097
2098 Finally, test_support.HOST has been introduced, which should be used
2099 for the host argument of any relevant socket calls (i.e. bind and
2100 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002101
2102 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002103 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002104 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2105 test_asynchat and test_socket_ssl.
2106
Georg Brandl3ee81df2008-05-17 18:14:43 +00002107 It is now possible for multiple instances of the regression test
2108 suite to run in parallel without issue.

2161
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002162- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002163 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2164 Plane. This affected raw unicode literals and the
2165 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2166 this case, like normal unicode literals and the 'unicode-escape'
2167 codec.

2375-----------------
2376
Fred Drakea8ee94b2008-03-01 02:45:07 +00002377- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002378 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002383
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002384- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002385 issue 215555 for a discussion.
2386
Eric Smitha73fbe72008-02-23 03:09:44 +00002387- Added the future_builtins module, which contains hex() and oct().
2388 These are the PEP 3127 version of these functions, designed to be
2389 compatible with the hex() and oct() builtins from Python 3.0. They
2390 differ slightly in their output formats from the existing, unchanged
2391 Python 2.6 builtins. The expected usage of the future_builtins
2392 module is:
2393 from future_builtins import hex, oct
2394
Eric Smith7ef40bf2008-02-20 23:34:22 +00002395- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2396 exponents for exponents with absolute value < 100. Follows C99
2397 standard. This is a change on Windows, which would use 3 digits.
2398 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2399 so that any alterations it does to the resulting string will be
2400 available in stringlib/formatter.h (for float.__format__).
2401
Eric Smith5a3c1352008-02-19 13:21:56 +00002402- Implemented PEP 3101, Advanced String Formatting. This adds a new
2403 builtin format(); a format() method for str and unicode; a
2404 __format__() method to object, str, unicode, int, long, float, and
2405 datetime; the class string.Formatter; and the C API
2406 PyObject_Format().
2407
Georg Brandl3ee81df2008-05-17 18:14:43 +00002408- Fixed several potential crashes, all caused by specially crafted
2409 __del__ methods exploiting objects in temporarily inconsistent
2410 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002411
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002412- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002413 prevent a possible crash: an Abstract Base Class would try to access
2414 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002415

Georg Brandl3ee81df2008-05-17 18:14:43 +00002419- Clear all free lists during a gc.collect() of the highest generation
2420 in order to allow pymalloc to free more arenas. Python may give back
2421 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002422
Georg Brandl3ee81df2008-05-17 18:14:43 +00002423- Issue #2045: Fix an infinite recursion triggered when printing a

2438 calls. Python expected the return type int but the fork familie
2439 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002440
Georg Brandl3ee81df2008-05-17 18:14:43 +00002441- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002453- Patch #1473257: generator objects gain a gi_code attribute. This is
2454 the same object as the func_code attribute of the function that
2455 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002456
Georg Brandl3ee81df2008-05-17 18:14:43 +00002457- Issue #1920: "while 0" statements were completely removed by the
2458 compiler, even in the presence of an "else" clause, which is
2459 supposed to be run when the condition is false. Now the compiler
2460 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002461
Guido van Rossumeead05f2008-01-24 18:21:02 +00002462- A few crashers fixed: weakref_in_del.py (issue #1377858);
2463 loosing_dict_ref.py (issue #1303614, test67.py);
2464 borrowed_ref_[34].py (not in tracker).

2469
Georg Brandl3ee81df2008-05-17 18:14:43 +00002470- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002471 several extension methods and modules do not work without unicode
2472 support.
2473
Georg Brandl26543b12008-01-21 18:36:51 +00002474- Issue #1882: when compiling code from a string, encoding cookies in the

2478
Georg Brandl6caad7d2008-01-26 14:19:22 +00002479- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002480 added.
2481
Christian Heimesc94e2b52008-01-14 04:13:37 +00002482- sys.float_info / PyFloat_GetInfo: The floating point information
2483 object was converted from a dict to a specialized structseq object.
2484
Georg Brandl3ee81df2008-05-17 18:14:43 +00002485- Patch #1816: Added sys.flags structseq. It exposes the status of
2486 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002487
Georg Brandl3ee81df2008-05-17 18:14:43 +00002488- Objects/structseq.c: Implemented new structseq representation. The
2489 patch makes structseqs (e.g. the return value of os.stat) more
2490 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002491
Georg Brandl3ee81df2008-05-17 18:14:43 +00002492- Patch #1700288: added a type attribute cache that caches method
2493 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002494
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002495- Bug #1776: __import__() no longer accepts filenames on any platform.
2496 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002497

2501 envvar and sys.dont_write_bytecode attribute. All these can be set
2502 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002503
Georg Brandl3ee81df2008-05-17 18:14:43 +00002504- Improve some exception messages when Windows fails to load an
2505 extension module. Now we get for example '%1 is not a valid Win32
2506 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002507

2563
Georg Brandl3ee81df2008-05-17 18:14:43 +00002564- The enumerate() builtin function is no longer bounded to sequences
2565 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2566 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002567
Georg Brandl3ee81df2008-05-17 18:14:43 +00002568- Issue #1686386: Tuple's tp_repr did not take into account the
2569 possibility of having a self-referential tuple, which is possible
2570 from C code. Nor did object's tp_str consider that a type's tp_str
2571 could do something that could lead to an inifinite recursion.
2572 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2573 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002574
Georg Brandl3ee81df2008-05-17 18:14:43 +00002575- Issue #1164: It was possible to trigger deadlock when using the
2576 'print' statement to write to a file since the GIL was not released
2577 as needed. Now PyObject_Print() does the right thing along with
2578 various tp_print implementations of the built-in types and those in
2579 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002580

Georg Brandl3ee81df2008-05-17 18:14:43 +00002589 PyObject_Call() never calling back out to Python code to trigger
2590 recursion depth updates/checks. Required the creation of a static
2591 RuntimeError instance in case normalizing an exception put the
2592 recursion check value past its limit. Fixes crashers

2616 calls.
2617
Collin Winter62903052007-05-18 23:11:24 +00002618- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002619 "except E as target:". This is to provide forwards compatibility
2620 with Python 3.0.

2642 now stricter in rejecting excess arguments. The only time when
2643 either allows excess arguments is when it is not overridden and the
2644 other one is. For backwards compatibility, when both are
2645 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002646 warning later). Also, type.__init__() insists on the same signature
2647 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002649- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2650 object to complex using its __complex__() method before falling back
2651 to the __float__() method. Therefore, the functions in the cmath
2652 module now can operate on objects that define a __complex__()
2653 method.

2673
Georg Brandl871f1bc2007-03-12 13:17:36 +00002674- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002675 its argument, if it exists. If not, it will work like before. This
2676 allows customizing the output of dir() in the presence of a
2677 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002689- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002690 makes the filenames the warning module prints much more sensible
2691 when a PYTHONSTARTUP file is used.

2706
Georg Brandl3ee81df2008-05-17 18:14:43 +00002707- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00002759- Bug #1545497: when given an explicit base, int() did ignore NULs
2760 embedded in the string to convert.
2761
Georg Brandl846f73a2006-10-08 07:11:54 +00002762- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003619- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3620 with RFC 3207 and forgets any knowledge obtained from the server not
3621 obtained from the TLS negotiation itself. Patch contributed by Bill
3622 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003623
Georg Brandl3ee81df2008-05-17 18:14:43 +00003624- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003625 that the SMTP.starttls() caller no longer needs to call ehlo()
3626 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003627 does not claim to support starttls. Adds the
3628 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3629 Fenner.

3709 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3710 silently miscode subclasses of those types. Now, it raises a
3711 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003712

Georg Brandl3ee81df2008-05-17 18:14:43 +00003727 time so that opening a database previously created with the DB_DUP
3728 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3729 opens. Specifically: dictionary assignment to a DB object will
3730 replace all values for a given key when the database allows
3731 duplicate values. DB users should use DB.put(k, v) when they want
3732 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003733

3739 characters with ASCII value less than 32. Also, it correctly quotes
3740 dots only if they occur on a single line, as opposed to the previous
3741 behavior of quoting dots if they are the second character of any
3742 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003743
