Georg Brandld2094602008-12-05 08:51:30 +0000470 method on file objects with closefd=False. The file descriptor is still

841What's New in Python 2.6.1
842==========================
843
844*Release date: 04-Dec-2008*
845
846Core and Builtins
847-----------------
848
849- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
850 interpreter to abort ("Fatal Python error: Could not reset the stack!")
851 instead of throwing a MemoryError.
852
853- Issue #4367: Python would segfault during compiling when the unicodedata
854 module couldn't be imported and \N escapes were present.
855
856- Issue #4348: Some bytearray methods returned that didn't cause any change to
857 the bytearray, returned the same bytearray instead of a copy.
858
859- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
860
861- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
862
863- Issue #4048: The parser module now correctly validates relative imports.
864
865- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
866 exec statement.
867
868- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
869 method does not return iterators for the 4th and 5th items.
870
871- Issue #4209: Enabling unicode_literals and the print_function in the same
872 __future__ import didn't work.
873
874- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
875 returned a path longer than MAX_PATH. (But It's doubtful this code path is
876 really executed because I cannot move to such directory on win2k)
877
878- Issue #4069: When set.remove(element) is used with a set element, the element
879 is temporarily replaced with an equivalent frozenset. But the eventual
880 KeyError would always report the empty frozenset([]) as the missing key. Now
881 it correctly refers to the initial element.
882
883- Fixed C99 style comments in several files. Python is now C89 compatible
884 again.

1011- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1012 AttributeError instead of RuntimeError, depending in which C API call
1013 exactly the recursion limit is exceeded. Consequently, both exception types
1014 are caught and silenced.

1030
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001031- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1032
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001033- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1034 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1035 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1036 ``printf`` function, whereas PyString_FromFormat has an independent
1037 implementation and uses "%zd" on all platforms for size_t values.
1038 This makes a difference on win64, where ``printf`` needs "%Id" to display
1039 64bit values.
1040
Benjamin Peterson97179b02008-09-09 20:55:01 +00001041- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1042 error.
1043
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001044- Issue #3777: long() applied to a float object now always return a long
1045 object; previously an int would be returned for small values. the __long__
1046 method is allowed to return either an int or a long, but the behaviour of
1047 float objects should not change to respect backward compatibility.
1048
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001049- Issue #3751: str.rpartition would perform a left-partition when called with
1050 a unicode argument.
1051
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001052- Issue #3683: Fix compilation when --without-threads is given.
1053
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001054- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001055 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001056 was correctly parsed but parsing of subsequent arguments failed.
1057
Vinay Sajip35e3b032008-09-01 14:33:59 +00001058- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001059 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1060 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1061 when given a tuple of classes as second argument, were looking up
1062 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1063 type object.
1064
Neal Norwitz18aa3882008-08-24 05:04:52 +00001065- Fix crashes on memory allocation failure found with failmalloc.
1066
1067- Fix memory leaks found with valgrind and update suppressions file.
1068
1069- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1070
1071- Fix problem using wrong name in decimal module reported by pychecker.
1072
Christian Heimes7d4c3172008-08-22 19:47:25 +00001073- Silenced another compiler warning about a used but not defined
1074 function 'stringlib_contains_obj'.

1077 ``__delslice__``.
1078
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001079- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1080 library targets in the Makefile.
1081
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001082- Issue #1204: The configure script now tests for additional libraries
1083 that may be required when linking against readline. This fixes issues
1084 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1102 silent misbehaviour when a single instance is nested in multiple
1103 with statements, or when the methods are invoked in the wrong order.
1104
Vinay Sajip844f7412008-09-09 13:42:08 +00001105- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.

Nick Coghland2e09382008-09-11 12:11:06 +00001107- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001108 return a list or None rather than a custom object.

1134 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1135 for catch_warnings() also led to an improvement in the raising of a
1136 DeprecationWarning related to warnings.warn_explicit().
1137
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001138- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001203
1204Core and Builtins
1205-----------------
1206
Guido van Rossumf8402962008-08-20 15:01:50 +00001207- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1208 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1209 extensions do not automatically benefit from the class attribute
1210 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1211 to their tp_flags field if they care. This is a backwards
1212 compatibility feature; in 3.0, all types will use the cache by
1213 default.
1214
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001215- Keyword arguments can now follow starred arguments. (``f(a, *args,
1216 keyword=23)`` is now valid syntax.)
1217
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001218- ctypes function pointers that are COM methods have a boolean True
1219 value again.
1220
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001221- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1222 by denying s# to parse objects that have a releasebuffer procedure,
1223 and introducing s*.
1224
Georg Brandl1e13ea92008-08-11 09:07:59 +00001225- Issue #3537: Fix an assertion failure when an empty but presized dict
1226 object was stored in the freelist.
1227
Mark Dickinsonb6467572008-08-04 21:30:09 +00001228- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1229 ValueError consistently across platforms.
1230
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001231- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1232 (64bit Unix, for example), unichr() would truncate its argument and return
1233 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1234
Neal Norwitze7d8be82008-07-31 17:17:14 +00001235- Apply security patches from Apple.
1236
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001237- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1238 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1239
Antoine Pitrou92f82162008-07-25 22:22:08 +00001240- Issue #1819: function calls with several named parameters are now on
1241 average 35% faster (as measured by pybench).
1242
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001243- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1244 the python debugger steps into a class statement: the free variables (local
1245 variables defined in an outer scope) would be deleted from the outer scope.
1246
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001247- Issue #2620: Overflow checking when allocating or reallocating memory
1248 was not always being done properly in some python types and extension
1249 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1250 all been updated to perform better checks and places in the code that
1251 would previously leak memory on the error path when such an allocation
1252 failed have been fixed.

1260 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1261
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001262- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1263 version reported by these tools does not necessarily follow the python
1264 version numbering scheme, so the module is less strict when parsing it.
1265
Nick Coghlanf70385a2008-08-18 12:42:46 +00001266- Issue #2235: Added Py3k warnings for types which will become unhashable
1267 under the stricter __hash__ inheritance rules in 3.0. Several types
1268 which did not meet the rules for hash invariants and were already
1269 unhashable in 3.0 have now been explicitly flagged as unhashable in
1270 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1271 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1272
Brett Cannon88f801d2008-08-18 00:46:22 +00001273- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1274 imported into the module but exposed as part of the module's API.

1281
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001282- Issue #3575: Incremental decoder's decode function now takes bytearray
1283 by using 's*' instead of 't#'.
1284
Jesus Cea585ad8a2009-07-02 15:37:21 +00001285- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001286 fails unicode conversion on 2nd parameter. (windows only)
1287
Facundo Batista94f243a2008-08-17 03:38:39 +00001288- Issue 2464. urllib2 now supports a malformation in the URL received
1289 in a redirect.

1320 to _sre.compile() will now be rejected. This should not affect anybody
1321 since the re.compile() function never generates invalid re-bytecode.

Antoine Pitroude781a42008-08-09 12:43:23 +00001342 asking for a specific length. This problem only affected files opened

1370 mode 0600 rather than 000 under Unix.
1371
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001372- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1386
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001387- Issue #643841: The language reference now provides more detailed

1399-----------------
1400
Georg Brandl3e483f62008-07-16 22:57:41 +00001401- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1402 its methods now allow for items objects that can be converted to
1403 an integer using operator.index().
1404
Mark Dickinson64b7e502008-07-16 09:40:03 +00001405- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1406 produced a ValueError instead of giving the correct float.
1407
Eric Smitha5fa5a22008-07-16 00:11:49 +00001408- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1409 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1410
Mark Dickinson7103aa42008-07-15 19:08:33 +00001411- Issue #3008: the float type has a new instance method 'float.hex'
1412 and a new class method 'float.fromhex' to convert floating-point
1413 numbers to and from hexadecimal strings, respectively.
1414
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001415- Issue #2235: __hash__ is once again inherited by default. To allow
1416 collections.Hashable to remain meaningful in the presence of the
1417 default hash implementation (object.__hash__), it is now possible
1418 to explicit block inheritance of hash by setting __hash__=None at
1419 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1420 level.
1421
Nick Coghlanb028f502008-07-13 14:52:36 +00001422- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1423 the parent module cannot be found while performing an absolute import.
1424 This means that an incorrectly defined __package__ attribute will
1425 now only prevent relative imports in that module rather than causing
1426 all imports from that module to fail.
1427
Nick Coghlan14ff9942008-07-08 14:21:42 +00001428- Issue #2517: Allow unicode messages in Exceptions again by correctly

1438 another thread's dictionary.
1439
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001440- Issue #3004: Minor change to slice.indices(): the start and stop
1441 arguments are now treated identically, making the behaviour easier
1442 to describe and understand. For example, slice(None, -10,
1443 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1444 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1445 10, -1).
1446
Georg Brandl278fc502008-07-19 12:46:12 +00001447- Issue #3219: Calling a function with repeated keyword arguments,
1448 f(a=2, a=23), would not cause a syntax error. This was a regression
1449 from 2.4 caused by the switch to the new compiler.

1460 error when they failed.
1461
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001462- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001487- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1488 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001489 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001490 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001506- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1896
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001897- On MacOS X it is now possible to install the framework in 64-bit
1898 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001899 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001900
1901 This is controlled by the configure argument ``--with-universal-archs``:
1902
1903 - ``--with-universal-archs=all``: install 4-way universal
1904
1905 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1906
1907 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1908
1909 This option should be used in combination with ``--enable-universalsdk=``.
1910
1911 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 +00001961- Issue #1631171: Re-implement the 'warnings' module in C (the
1962 original Python code has been kept as backup). This will allow for
1963 using the 'warning's machinery in such places as the parser where
1964 use of pure Python code is not possible. Both the ``showarning()``
1965 and ``formatwarning()`` gain an optional 'line' argument which is
1966 not called by default for backwards-compatibility reasons. Setting
1967 ``warnings.showwarning()`` to an implementation that lacks support
1968 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002031- Issue #2550: The approach used by client/server code for obtaining
2032 ports to listen on in network-oriented tests has been refined in an
2033 effort to facilitate running multiple instances of the entire
2034 regression test suite in parallel without issue.
2035 test_support.bind_port() has been fixed such that it will always
2036 return a unique port -- which wasn't always the case with the
2037 previous implementation, especially if socket options had been set
2038 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2039 new implementation of bind_port() will actually raise an exception
2040 if it is passed an AF_INET/SOCK_STREAM socket with either the
2041 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2042 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2043 the socket it's been passed. This currently only applies to
2044 Windows. This option prevents any other sockets from binding to the
2045 host/port we've bound to, thus removing the possibility of the
2046 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2047 when a second SOCK_STREAM socket binds and accepts to a host/port
2048 that's already been bound by another socket. The optional preferred
2049 port parameter to bind_port() has been removed. Under no
2050 circumstances should tests be hard coding ports!
2051
2052 test_support.find_unused_port() has also been introduced, which will
2053 pass a temporary socket object to bind_port() in order to obtain an
2054 unused port. The temporary socket object is then closed and
2055 deleted, and the port is returned. This method should only be used
2056 for obtaining an unused port in order to pass to an external program
2057 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2058 a parameter to a server-oriented class that doesn't give you direct
2059 access to the underlying socket used.
2060
2061 Finally, test_support.HOST has been introduced, which should be used
2062 for the host argument of any relevant socket calls (i.e. bind and
2063 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002064
2065 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002066 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002067 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2068 test_asynchat and test_socket_ssl.
2069
Georg Brandl3ee81df2008-05-17 18:14:43 +00002070 It is now possible for multiple instances of the regression test
2071 suite to run in parallel without issue.

2338-----------------
2339
Fred Drakea8ee94b2008-03-01 02:45:07 +00002340- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002341 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002346
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002347- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002348 issue 215555 for a discussion.
2349
Eric Smitha73fbe72008-02-23 03:09:44 +00002350- Added the future_builtins module, which contains hex() and oct().
2351 These are the PEP 3127 version of these functions, designed to be
2352 compatible with the hex() and oct() builtins from Python 3.0. They
2353 differ slightly in their output formats from the existing, unchanged
2354 Python 2.6 builtins. The expected usage of the future_builtins
2355 module is:
2356 from future_builtins import hex, oct
2357
Eric Smith7ef40bf2008-02-20 23:34:22 +00002358- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2359 exponents for exponents with absolute value < 100. Follows C99
2360 standard. This is a change on Windows, which would use 3 digits.
2361 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2362 so that any alterations it does to the resulting string will be
2363 available in stringlib/formatter.h (for float.__format__).
2364
Eric Smith5a3c1352008-02-19 13:21:56 +00002365- Implemented PEP 3101, Advanced String Formatting. This adds a new
2366 builtin format(); a format() method for str and unicode; a
2367 __format__() method to object, str, unicode, int, long, float, and
2368 datetime; the class string.Formatter; and the C API
2369 PyObject_Format().
2370
Georg Brandl3ee81df2008-05-17 18:14:43 +00002371- Fixed several potential crashes, all caused by specially crafted
2372 __del__ methods exploiting objects in temporarily inconsistent
2373 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002374
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002375- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002376 prevent a possible crash: an Abstract Base Class would try to access
2377 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002378
Georg Brandl3ee81df2008-05-17 18:14:43 +00002379- Fixed repr() and str() of complex numbers with infinity or nan as
2380 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002381
Georg Brandl3ee81df2008-05-17 18:14:43 +00002382- Clear all free lists during a gc.collect() of the highest generation
2383 in order to allow pymalloc to free more arenas. Python may give back
2384 memory to the OS earlier.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002386- Issue #2045: Fix an infinite recursion triggered when printing a
2387 subclass of collections.defaultdict, if its default_factory is set
2388 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002389
Christian Heimesf75dbef2008-02-08 00:11:31 +00002390- Fixed a minor memory leak in dictobject.c. The content of the free
2391 list was not freed on interpreter shutdown.
2392
Georg Brandl3ee81df2008-05-17 18:14:43 +00002393- Limit free list of method and builtin function objects to 256
2394 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002395
Georg Brandl3ee81df2008-05-17 18:14:43 +00002396- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2397 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002398 to compact the internal free lists of pre-allocted ints and floats.
2399
Georg Brandl3ee81df2008-05-17 18:14:43 +00002400- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2401 calls. Python expected the return type int but the fork familie
2402 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002403
Georg Brandl3ee81df2008-05-17 18:14:43 +00002404- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2405 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002406
Georg Brandl3ee81df2008-05-17 18:14:43 +00002407- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2408 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002409
Georg Brandl3ee81df2008-05-17 18:14:43 +00002410- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00002413- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2414 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002415
Georg Brandl3ee81df2008-05-17 18:14:43 +00002416- Patch #1473257: generator objects gain a gi_code attribute. This is
2417 the same object as the func_code attribute of the function that
2418 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002419
Georg Brandl3ee81df2008-05-17 18:14:43 +00002420- Issue #1920: "while 0" statements were completely removed by the
2421 compiler, even in the presence of an "else" clause, which is
2422 supposed to be run when the condition is false. Now the compiler
2423 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002424
Guido van Rossumeead05f2008-01-24 18:21:02 +00002425- A few crashers fixed: weakref_in_del.py (issue #1377858);
2426 loosing_dict_ref.py (issue #1303614, test67.py);
2427 borrowed_ref_[34].py (not in tracker).
2428
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002429- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002430 suppressed while an extension is loaded by calling SetErrorMode in
2431 dynload_win.c. The error is still reported properly.
2432
Georg Brandl3ee81df2008-05-17 18:14:43 +00002433- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002434 several extension methods and modules do not work without unicode
2435 support.
2436
Georg Brandl26543b12008-01-21 18:36:51 +00002437- Issue #1882: when compiling code from a string, encoding cookies in the
2438 second line of code were not always recognized correctly.
2439
Georg Brandl14404b62008-01-19 19:27:05 +00002440- Issue #1679: "0x" was taken as a valid integer literal.
2441
Georg Brandl6caad7d2008-01-26 14:19:22 +00002442- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002443 added.
2444
Christian Heimesc94e2b52008-01-14 04:13:37 +00002445- sys.float_info / PyFloat_GetInfo: The floating point information
2446 object was converted from a dict to a specialized structseq object.
2447
Georg Brandl3ee81df2008-05-17 18:14:43 +00002448- Patch #1816: Added sys.flags structseq. It exposes the status of
2449 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002450
Georg Brandl3ee81df2008-05-17 18:14:43 +00002451- Objects/structseq.c: Implemented new structseq representation. The
2452 patch makes structseqs (e.g. the return value of os.stat) more
2453 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002454
Georg Brandl3ee81df2008-05-17 18:14:43 +00002455- Patch #1700288: added a type attribute cache that caches method
2456 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002457
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002458- Bug #1776: __import__() no longer accepts filenames on any platform.
2459 The first parameter to __import__() must be a valid module name.

2462
Georg Brandl3ee81df2008-05-17 18:14:43 +00002463- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2464 envvar and sys.dont_write_bytecode attribute. All these can be set
2465 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002466
Georg Brandl3ee81df2008-05-17 18:14:43 +00002467- Improve some exception messages when Windows fails to load an
2468 extension module. Now we get for example '%1 is not a valid Win32
2469 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002470

Christian Heimes0a8143f2007-12-18 23:22:54 +00002476- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002477 and INF. float("nan"), float("inf") and float("-inf") now work on
2478 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002479
Georg Brandl3ee81df2008-05-17 18:14:43 +00002480- Compiler now generates simpler and faster code for dictionary
2481 literals. The oparg for BUILD_MAP now indicates an estimated
2482 dictionary size. There is a new opcode, STORE_MAP, for adding
2483 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002512- Patch #1739468: Directories and zipfiles containing a __main__.py
2513 file can now be directly executed by passing their name to the
2514 interpreter. The directory/zipfile is automatically inserted as the
2515 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002517- Issue #1265: Fix a problem with sys.settrace, if the tracing
2518 function uses a generator expression when at the same time the
2519 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002520
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002521- sets and frozensets now have an isdisjoint() method.
2522

2524
Neal Norwitz44f326e2007-10-05 05:29:17 +00002525- Fix warnings found by the new version of the Coverity checker.
2526
Georg Brandl3ee81df2008-05-17 18:14:43 +00002527- The enumerate() builtin function is no longer bounded to sequences
2528 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2529 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002530
Georg Brandl3ee81df2008-05-17 18:14:43 +00002531- Issue #1686386: Tuple's tp_repr did not take into account the
2532 possibility of having a self-referential tuple, which is possible
2533 from C code. Nor did object's tp_str consider that a type's tp_str
2534 could do something that could lead to an inifinite recursion.
2535 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2536 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002537
Georg Brandl3ee81df2008-05-17 18:14:43 +00002538- Issue #1164: It was possible to trigger deadlock when using the
2539 'print' statement to write to a file since the GIL was not released
2540 as needed. Now PyObject_Print() does the right thing along with
2541 various tp_print implementations of the built-in types and those in
2542 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002543
Georg Brandl3ee81df2008-05-17 18:14:43 +00002544- Issue #1147: Exceptions were directly allowing string exceptions in
2545 their throw() method even though string exceptions no longer
2546 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002547
Georg Brandl3ee81df2008-05-17 18:14:43 +00002548- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002550
Brett Cannon1e534b52007-09-07 04:18:30 +00002551- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002552 PyObject_Call() never calling back out to Python code to trigger
2553 recursion depth updates/checks. Required the creation of a static
2554 RuntimeError instance in case normalizing an exception put the
2555 recursion check value past its limit. Fixes crashers
2556 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002557

Neal Norwitz0ac60192007-05-27 04:08:54 +00002571- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002572 __*__ attributes. (Some already existed, e.g., __doc__ and
2573 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002574
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002575- Add -3 option to the interpreter to warn about features that are
2576 deprecated and will be changed/removed in Python 3.0.
2577
Georg Brandl2134e752007-05-21 20:34:16 +00002578- Patch #1686487: you can now pass any mapping after '**' in function
2579 calls.
2580
Collin Winter62903052007-05-18 23:11:24 +00002581- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002582 "except E as target:". This is to provide forwards compatibility
2583 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00002585- Deprecate BaseException.message as per PEP 352.
2586
Georg Brandl3ee81df2008-05-17 18:14:43 +00002587- Issue #1303614: don't expose object's __dict__ when the dict is

2589
Vinay Sajip8549ce32007-05-06 17:53:37 +00002590- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002591 setting a plain string, ie don't expand to single letter identifiers.
2592
Raymond Hettinger13936692007-04-11 18:40:58 +00002593- Request #1191699: Slices can now be pickled.
2594
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002595- Request #1193128: str.translate() now allows a None argument for
2596 translations that only remove characters without re-mapping the
2597 remaining characters.
2598
Georg Brandl5cb76c12007-03-21 09:00:39 +00002599- Patch #1682205: a TypeError while unpacking an iterable is no longer
2600 masked by a generic one with the message "unpack non-sequence".
2601
Neal Norwitzaa754b72007-03-21 06:39:48 +00002602- Remove unused file Python/fmod.c.
2603
Guido van Rossum143b5642007-03-23 04:58:42 +00002604- Bug #1683368: The object.__init__() and object.__new__() methods are
2605 now stricter in rejecting excess arguments. The only time when
2606 either allows excess arguments is when it is not overridden and the
2607 other one is. For backwards compatibility, when both are
2608 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002609 warning later). Also, type.__init__() insists on the same signature
2610 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002612- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2613 object to complex using its __complex__() method before falling back
2614 to the __float__() method. Therefore, the functions in the cmath
2615 module now can operate on objects that define a __complex__()
2616 method.

Georg Brandlaa2321b2007-03-07 00:40:28 +00002652- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00002722- Bug #1545497: when given an explicit base, int() did ignore NULs
2723 embedded in the string to convert.
2724
Georg Brandl846f73a2006-10-08 07:11:54 +00002725- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003205 AttributeError instead of an IOError when the server's response

3297 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00003690 time so that opening a database previously created with the DB_DUP
3691 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3692 opens. Specifically: dictionary assignment to a DB object will
3693 replace all values for a given key when the database allows
3694 duplicate values. DB users should use DB.put(k, v) when they want
3695 to store duplicates; not DB[k] = v.

3702 characters with ASCII value less than 32. Also, it correctly quotes
3703 dots only if they occur on a single line, as opposed to the previous
3704 behavior of quoting dots if they are the second character of any
3705 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003706
