Georg Brandld2094602008-12-05 08:51:30 +0000501 method on file objects with closefd=False. The file descriptor is still

674 do an explicit seek to the end of file (so that e.g. tell() returns the

711 302 conformant loader) will now work correctly in most cases (they
712 are still subject to the constraints that exist for all code running
713 from inside a module loaded via a PEP 302 loader and attempting to

872What's New in Python 2.6.1
873==========================
874
875*Release date: 04-Dec-2008*
876
877Core and Builtins
878-----------------
879
880- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
881 interpreter to abort ("Fatal Python error: Could not reset the stack!")
882 instead of throwing a MemoryError.
883
884- Issue #4367: Python would segfault during compiling when the unicodedata
885 module couldn't be imported and \N escapes were present.
886
887- Issue #4348: Some bytearray methods returned that didn't cause any change to
888 the bytearray, returned the same bytearray instead of a copy.
889
890- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
891
892- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
893
894- Issue #4048: The parser module now correctly validates relative imports.
895
896- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
897 exec statement.
898
899- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
900 method does not return iterators for the 4th and 5th items.
901
902- Issue #4209: Enabling unicode_literals and the print_function in the same
903 __future__ import didn't work.
904
905- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
906 returned a path longer than MAX_PATH. (But It's doubtful this code path is
907 really executed because I cannot move to such directory on win2k)
908
909- Issue #4069: When set.remove(element) is used with a set element, the element
910 is temporarily replaced with an equivalent frozenset. But the eventual
911 KeyError would always report the empty frozenset([]) as the missing key. Now
912 it correctly refers to the initial element.
913
914- Fixed C99 style comments in several files. Python is now C89 compatible
915 again.

1061
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001062- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1063
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001064- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1065 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1066 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1067 ``printf`` function, whereas PyString_FromFormat has an independent
1068 implementation and uses "%zd" on all platforms for size_t values.
1069 This makes a difference on win64, where ``printf`` needs "%Id" to display
1070 64bit values.
1071
Benjamin Peterson97179b02008-09-09 20:55:01 +00001072- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1073 error.
1074
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001075- Issue #3777: long() applied to a float object now always return a long
1076 object; previously an int would be returned for small values. the __long__
1077 method is allowed to return either an int or a long, but the behaviour of
1078 float objects should not change to respect backward compatibility.
1079
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001080- Issue #3751: str.rpartition would perform a left-partition when called with
1081 a unicode argument.
1082
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001083- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001085- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001086 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001087 was correctly parsed but parsing of subsequent arguments failed.
1088
Vinay Sajip35e3b032008-09-01 14:33:59 +00001089- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001090 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1091 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1092 when given a tuple of classes as second argument, were looking up
1093 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1094 type object.
1095
Neal Norwitz18aa3882008-08-24 05:04:52 +00001096- Fix crashes on memory allocation failure found with failmalloc.
1097
1098- Fix memory leaks found with valgrind and update suppressions file.
1099
1100- Fix compiler warnings in opt mode which would lead to invalid memory reads.

1165 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1166 for catch_warnings() also led to an improvement in the raising of a
1167 DeprecationWarning related to warnings.warn_explicit().

1235Core and Builtins
1236-----------------
1237
Guido van Rossumf8402962008-08-20 15:01:50 +00001238- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1239 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1240 extensions do not automatically benefit from the class attribute
1241 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1242 to their tp_flags field if they care. This is a backwards
1243 compatibility feature; in 3.0, all types will use the cache by
1244 default.
1245
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001246- Keyword arguments can now follow starred arguments. (``f(a, *args,
1247 keyword=23)`` is now valid syntax.)
1248
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001249- ctypes function pointers that are COM methods have a boolean True
1250 value again.
1251
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001252- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1253 by denying s# to parse objects that have a releasebuffer procedure,
1254 and introducing s*.
1255
Georg Brandl1e13ea92008-08-11 09:07:59 +00001256- Issue #3537: Fix an assertion failure when an empty but presized dict
1257 object was stored in the freelist.
1258
Mark Dickinsonb6467572008-08-04 21:30:09 +00001259- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1260 ValueError consistently across platforms.
1261
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001262- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1263 (64bit Unix, for example), unichr() would truncate its argument and return
1264 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1265
Neal Norwitze7d8be82008-07-31 17:17:14 +00001266- Apply security patches from Apple.
1267
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001268- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1269 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1270
Antoine Pitrou92f82162008-07-25 22:22:08 +00001271- Issue #1819: function calls with several named parameters are now on
1272 average 35% faster (as measured by pybench).
1273
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001274- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1275 the python debugger steps into a class statement: the free variables (local
1276 variables defined in an outer scope) would be deleted from the outer scope.
1277
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001278- Issue #2620: Overflow checking when allocating or reallocating memory
1279 was not always being done properly in some python types and extension
1280 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1281 all been updated to perform better checks and places in the code that
1282 would previously leak memory on the error path when such an allocation
1283 failed have been fixed.

1289
Benjamin Petersone977ad42008-08-20 01:42:01 +00001290- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1291 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1292
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001293- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1294 version reported by these tools does not necessarily follow the python
1295 version numbering scheme, so the module is less strict when parsing it.
1296
Nick Coghlanf70385a2008-08-18 12:42:46 +00001297- Issue #2235: Added Py3k warnings for types which will become unhashable
1298 under the stricter __hash__ inheritance rules in 3.0. Several types
1299 which did not meet the rules for hash invariants and were already
1300 unhashable in 3.0 have now been explicitly flagged as unhashable in
1301 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1302 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1303
Brett Cannon88f801d2008-08-18 00:46:22 +00001304- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1305 imported into the module but exposed as part of the module's API.
1306

1430-----------------
1431
Georg Brandl3e483f62008-07-16 22:57:41 +00001432- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1433 its methods now allow for items objects that can be converted to
1434 an integer using operator.index().
1435
Mark Dickinson64b7e502008-07-16 09:40:03 +00001436- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1437 produced a ValueError instead of giving the correct float.
1438
Eric Smitha5fa5a22008-07-16 00:11:49 +00001439- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1440 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1441
Mark Dickinson7103aa42008-07-15 19:08:33 +00001442- Issue #3008: the float type has a new instance method 'float.hex'
1443 and a new class method 'float.fromhex' to convert floating-point
1444 numbers to and from hexadecimal strings, respectively.
1445
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001446- Issue #2235: __hash__ is once again inherited by default. To allow
1447 collections.Hashable to remain meaningful in the presence of the
1448 default hash implementation (object.__hash__), it is now possible
1449 to explicit block inheritance of hash by setting __hash__=None at
1450 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1451 level.
1452
Nick Coghlanb028f502008-07-13 14:52:36 +00001453- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1454 the parent module cannot be found while performing an absolute import.
1455 This means that an incorrectly defined __package__ attribute will
1456 now only prevent relative imports in that module rather than causing
1457 all imports from that module to fail.
1458
Nick Coghlan14ff9942008-07-08 14:21:42 +00001459- Issue #2517: Allow unicode messages in Exceptions again by correctly
1460 bypassing the instance dictionary when looking up __unicode__ on
1461 new-style classes.

1469 another thread's dictionary.
1470
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001471- Issue #3004: Minor change to slice.indices(): the start and stop
1472 arguments are now treated identically, making the behaviour easier
1473 to describe and understand. For example, slice(None, -10,
1474 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1475 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1476 10, -1).
1477
Georg Brandl278fc502008-07-19 12:46:12 +00001478- Issue #3219: Calling a function with repeated keyword arguments,
1479 f(a=2, a=23), would not cause a syntax error. This was a regression
1480 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001481
Georg Brandl278fc502008-07-19 12:46:12 +00001482- Issue #2862: Make int and float freelist management consistent with
1483 other freelists. Changes their CompactFreeList apis into

1491 error when they failed.
1492
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001493- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001518- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1519 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001520 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001521 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001537- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1929 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001930 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001931
1932 This is controlled by the configure argument ``--with-universal-archs``:
1933
1934 - ``--with-universal-archs=all``: install 4-way universal
1935
1936 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1937
1938 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1939
1940 This option should be used in combination with ``--enable-universalsdk=``.
1941
1942 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 +00001992- Issue #1631171: Re-implement the 'warnings' module in C (the
1993 original Python code has been kept as backup). This will allow for
1994 using the 'warning's machinery in such places as the parser where
1995 use of pure Python code is not possible. Both the ``showarning()``
1996 and ``formatwarning()`` gain an optional 'line' argument which is
1997 not called by default for backwards-compatibility reasons. Setting
1998 ``warnings.showwarning()`` to an implementation that lacks support
1999 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002062- Issue #2550: The approach used by client/server code for obtaining
2063 ports to listen on in network-oriented tests has been refined in an
2064 effort to facilitate running multiple instances of the entire
2065 regression test suite in parallel without issue.
2066 test_support.bind_port() has been fixed such that it will always
2067 return a unique port -- which wasn't always the case with the
2068 previous implementation, especially if socket options had been set
2069 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2070 new implementation of bind_port() will actually raise an exception
2071 if it is passed an AF_INET/SOCK_STREAM socket with either the
2072 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2073 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2074 the socket it's been passed. This currently only applies to
2075 Windows. This option prevents any other sockets from binding to the
2076 host/port we've bound to, thus removing the possibility of the
2077 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2078 when a second SOCK_STREAM socket binds and accepts to a host/port
2079 that's already been bound by another socket. The optional preferred
2080 port parameter to bind_port() has been removed. Under no
2081 circumstances should tests be hard coding ports!
2082
2083 test_support.find_unused_port() has also been introduced, which will
2084 pass a temporary socket object to bind_port() in order to obtain an
2085 unused port. The temporary socket object is then closed and
2086 deleted, and the port is returned. This method should only be used
2087 for obtaining an unused port in order to pass to an external program
2088 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2089 a parameter to a server-oriented class that doesn't give you direct
2090 access to the underlying socket used.
2091
2092 Finally, test_support.HOST has been introduced, which should be used
2093 for the host argument of any relevant socket calls (i.e. bind and
2094 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002095
2096 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002097 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002098 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2099 test_asynchat and test_socket_ssl.
2100
Georg Brandl3ee81df2008-05-17 18:14:43 +00002101 It is now possible for multiple instances of the regression test
2102 suite to run in parallel without issue.

2155
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002156- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002157 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2158 Plane. This affected raw unicode literals and the
2159 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2160 this case, like normal unicode literals and the 'unicode-escape'
2161 codec.

2370
Fred Drakea8ee94b2008-03-01 02:45:07 +00002371- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002372 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002377
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002378- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002379 issue 215555 for a discussion.
2380
Eric Smitha73fbe72008-02-23 03:09:44 +00002381- Added the future_builtins module, which contains hex() and oct().
2382 These are the PEP 3127 version of these functions, designed to be
2383 compatible with the hex() and oct() builtins from Python 3.0. They
2384 differ slightly in their output formats from the existing, unchanged
2385 Python 2.6 builtins. The expected usage of the future_builtins
2386 module is:
2387 from future_builtins import hex, oct
2388
Eric Smith7ef40bf2008-02-20 23:34:22 +00002389- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2390 exponents for exponents with absolute value < 100. Follows C99
2391 standard. This is a change on Windows, which would use 3 digits.
2392 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2393 so that any alterations it does to the resulting string will be
2394 available in stringlib/formatter.h (for float.__format__).
2395
Eric Smith5a3c1352008-02-19 13:21:56 +00002396- Implemented PEP 3101, Advanced String Formatting. This adds a new
2397 builtin format(); a format() method for str and unicode; a
2398 __format__() method to object, str, unicode, int, long, float, and
2399 datetime; the class string.Formatter; and the C API
2400 PyObject_Format().
2401
Georg Brandl3ee81df2008-05-17 18:14:43 +00002402- Fixed several potential crashes, all caused by specially crafted
2403 __del__ methods exploiting objects in temporarily inconsistent
2404 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002405
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002406- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002407 prevent a possible crash: an Abstract Base Class would try to access
2408 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002409

Georg Brandl3ee81df2008-05-17 18:14:43 +00002413- Clear all free lists during a gc.collect() of the highest generation
2414 in order to allow pymalloc to free more arenas. Python may give back
2415 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002416
Georg Brandl3ee81df2008-05-17 18:14:43 +00002417- Issue #2045: Fix an infinite recursion triggered when printing a
2418 subclass of collections.defaultdict, if its default_factory is set

Christian Heimesf75dbef2008-02-08 00:11:31 +00002421- Fixed a minor memory leak in dictobject.c. The content of the free
2422 list was not freed on interpreter shutdown.
2423
Georg Brandl3ee81df2008-05-17 18:14:43 +00002424- Limit free list of method and builtin function objects to 256
2425 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002426
Georg Brandl3ee81df2008-05-17 18:14:43 +00002427- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2428 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002429 to compact the internal free lists of pre-allocted ints and floats.
2430
Georg Brandl3ee81df2008-05-17 18:14:43 +00002431- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2432 calls. Python expected the return type int but the fork familie
2433 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002434
Georg Brandl3ee81df2008-05-17 18:14:43 +00002435- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002447- Patch #1473257: generator objects gain a gi_code attribute. This is
2448 the same object as the func_code attribute of the function that
2449 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002450
Georg Brandl3ee81df2008-05-17 18:14:43 +00002451- Issue #1920: "while 0" statements were completely removed by the
2452 compiler, even in the presence of an "else" clause, which is
2453 supposed to be run when the condition is false. Now the compiler
2454 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002455
Guido van Rossumeead05f2008-01-24 18:21:02 +00002456- A few crashers fixed: weakref_in_del.py (issue #1377858);
2457 loosing_dict_ref.py (issue #1303614, test67.py);
2458 borrowed_ref_[34].py (not in tracker).
2459
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002460- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002461 suppressed while an extension is loaded by calling SetErrorMode in
2462 dynload_win.c. The error is still reported properly.
2463
Georg Brandl3ee81df2008-05-17 18:14:43 +00002464- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002465 several extension methods and modules do not work without unicode
2466 support.
2467
Georg Brandl26543b12008-01-21 18:36:51 +00002468- Issue #1882: when compiling code from a string, encoding cookies in the
2469 second line of code were not always recognized correctly.
2470
Georg Brandl14404b62008-01-19 19:27:05 +00002471- Issue #1679: "0x" was taken as a valid integer literal.
2472
Georg Brandl6caad7d2008-01-26 14:19:22 +00002473- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002474 added.
2475
Christian Heimesc94e2b52008-01-14 04:13:37 +00002476- sys.float_info / PyFloat_GetInfo: The floating point information
2477 object was converted from a dict to a specialized structseq object.
2478
Georg Brandl3ee81df2008-05-17 18:14:43 +00002479- Patch #1816: Added sys.flags structseq. It exposes the status of
2480 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002481
Georg Brandl3ee81df2008-05-17 18:14:43 +00002482- Objects/structseq.c: Implemented new structseq representation. The
2483 patch makes structseqs (e.g. the return value of os.stat) more
2484 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002485
Georg Brandl3ee81df2008-05-17 18:14:43 +00002486- Patch #1700288: added a type attribute cache that caches method
2487 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002488
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002489- Bug #1776: __import__() no longer accepts filenames on any platform.
2490 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002491

2495 envvar and sys.dont_write_bytecode attribute. All these can be set
2496 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002497
Georg Brandl3ee81df2008-05-17 18:14:43 +00002498- Improve some exception messages when Windows fails to load an
2499 extension module. Now we get for example '%1 is not a valid Win32
2500 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002501

Christian Heimes0a8143f2007-12-18 23:22:54 +00002507- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002508 and INF. float("nan"), float("inf") and float("-inf") now work on
2509 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002510
Georg Brandl3ee81df2008-05-17 18:14:43 +00002511- Compiler now generates simpler and faster code for dictionary
2512 literals. The oparg for BUILD_MAP now indicates an estimated
2513 dictionary size. There is a new opcode, STORE_MAP, for adding
2514 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002543- Patch #1739468: Directories and zipfiles containing a __main__.py
2544 file can now be directly executed by passing their name to the
2545 interpreter. The directory/zipfile is automatically inserted as the
2546 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002547
Georg Brandl3ee81df2008-05-17 18:14:43 +00002548- Issue #1265: Fix a problem with sys.settrace, if the tracing
2549 function uses a generator expression when at the same time the
2550 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002551
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002552- sets and frozensets now have an isdisjoint() method.
2553

2555
Neal Norwitz44f326e2007-10-05 05:29:17 +00002556- Fix warnings found by the new version of the Coverity checker.
2557
Georg Brandl3ee81df2008-05-17 18:14:43 +00002558- The enumerate() builtin function is no longer bounded to sequences
2559 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2560 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002561
Georg Brandl3ee81df2008-05-17 18:14:43 +00002562- Issue #1686386: Tuple's tp_repr did not take into account the
2563 possibility of having a self-referential tuple, which is possible
2564 from C code. Nor did object's tp_str consider that a type's tp_str
2565 could do something that could lead to an inifinite recursion.
2566 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2567 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002568
Georg Brandl3ee81df2008-05-17 18:14:43 +00002569- Issue #1164: It was possible to trigger deadlock when using the
2570 'print' statement to write to a file since the GIL was not released
2571 as needed. Now PyObject_Print() does the right thing along with
2572 various tp_print implementations of the built-in types and those in
2573 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002574
Georg Brandl3ee81df2008-05-17 18:14:43 +00002575- Issue #1147: Exceptions were directly allowing string exceptions in

2577 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002578
Georg Brandl3ee81df2008-05-17 18:14:43 +00002579- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002582- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002583 PyObject_Call() never calling back out to Python code to trigger
2584 recursion depth updates/checks. Required the creation of a static
2585 RuntimeError instance in case normalizing an exception put the
2586 recursion check value past its limit. Fixes crashers
2587 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002588

Neal Norwitz0ac60192007-05-27 04:08:54 +00002602- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002603 __*__ attributes. (Some already existed, e.g., __doc__ and
2604 __name__.)

2610 calls.
2611
Collin Winter62903052007-05-18 23:11:24 +00002612- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002613 "except E as target:". This is to provide forwards compatibility
2614 with Python 3.0.

2620
Vinay Sajip8549ce32007-05-06 17:53:37 +00002621- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002622 setting a plain string, ie don't expand to single letter identifiers.
2623
Raymond Hettinger13936692007-04-11 18:40:58 +00002624- Request #1191699: Slices can now be pickled.
2625
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002626- Request #1193128: str.translate() now allows a None argument for

2628 remaining characters.
2629
Georg Brandl5cb76c12007-03-21 09:00:39 +00002630- Patch #1682205: a TypeError while unpacking an iterable is no longer
2631 masked by a generic one with the message "unpack non-sequence".
2632
Neal Norwitzaa754b72007-03-21 06:39:48 +00002633- Remove unused file Python/fmod.c.
2634
Guido van Rossum143b5642007-03-23 04:58:42 +00002635- Bug #1683368: The object.__init__() and object.__new__() methods are
2636 now stricter in rejecting excess arguments. The only time when
2637 either allows excess arguments is when it is not overridden and the
2638 other one is. For backwards compatibility, when both are
2639 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002640 warning later). Also, type.__init__() insists on the same signature
2641 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002643- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2644 object to complex using its __complex__() method before falling back
2645 to the __float__() method. Therefore, the functions in the cmath
2646 module now can operate on objects that define a __complex__()
2647 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002669 its argument, if it exists. If not, it will work like before. This
2670 allows customizing the output of dir() in the presence of a
2671 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002683- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00002753- Bug #1545497: when given an explicit base, int() did ignore NULs
2754 embedded in the string to convert.
2755
Georg Brandl846f73a2006-10-08 07:11:54 +00002756- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002804 generator expressions (x for x, in ... ) works again. Fixing this
2805 problem required changing the .pyc magic number. This means that
2806 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003613- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3614 with RFC 3207 and forgets any knowledge obtained from the server not
3615 obtained from the TLS negotiation itself. Patch contributed by Bill
3616 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003618- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003619 that the SMTP.starttls() caller no longer needs to call ehlo()
3620 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003621 does not claim to support starttls. Adds the
3622 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3703 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3704 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003721 time so that opening a database previously created with the DB_DUP
3722 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3723 opens. Specifically: dictionary assignment to a DB object will
3724 replace all values for a given key when the database allows
3725 duplicate values. DB users should use DB.put(k, v) when they want
3726 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003727

3733 characters with ASCII value less than 32. Also, it correctly quotes
3734 dots only if they occur on a single line, as opposed to the previous
3735 behavior of quoting dots if they are the second character of any
3736 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003737
