Vinay Sajip6badbe92009-01-20 22:49:13 +0000497- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000498 method on file objects with closefd=False. The file descriptor is still

Vinay Sajip9c786582009-02-08 19:14:41 +0000649- Issue #5132: Fixed trouble building extensions under Solaris with
Tarek Ziadéf28849a2009-02-05 22:55:00 +0000650 --enabled-shared activated. Initial patch by Dave Peterson.

653
Antoine Pitrou4ad77e22009-01-29 20:30:51 +0000654- Issue #2047: shutil.move() could believe that its destination path was
655 inside its source path if it began with the same letters (e.g. "src" vs.
656 "src.new").
657
Raymond Hettingerc9794482009-01-28 23:14:58 +0000658- Issue 4920: Fixed .next() vs .__next__() issues in the ABCs for

668 allow adding directories to a zipfile.
669
Antoine Pitrou19fec8b2009-01-21 00:56:37 +0000670- Issue #5008: When a file is opened in append mode with the new IO library,
671 do an explicit seek to the end of file (so that e.g. tell() returns the
672 file size rather than 0). This is consistent with the behaviour of the
673 traditional 2.x file object.
674
Amaury Forgeot d'Arc0293c802009-01-17 16:46:35 +0000675- Issue #3997: zipfiles generated with more than 65536 files could not be

Raymond Hettingerd263bd82008-12-31 04:18:44 +0000685- Issue 4790: The nsmallest() and nlargest() functions in the heapq module
686 did unnecessary work in the common case where no key function was specified.
687

704 zipimport (or any other conformant PEP 302 loader). Original patch by
705 Alexander Belopolsky.
706
707- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
708 302 conformant loader) will now work correctly in most cases (they
709 are still subject to the constraints that exist for all code running
710 from inside a module loaded via a PEP 302 loader and attempting to
711 perform IO operations based on __file__). Original patch by
712 Alexander Belopolsky.

869What's New in Python 2.6.1
870==========================
871
872*Release date: 04-Dec-2008*
873
874Core and Builtins
875-----------------
876
877- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
878 interpreter to abort ("Fatal Python error: Could not reset the stack!")
879 instead of throwing a MemoryError.
880
881- Issue #4367: Python would segfault during compiling when the unicodedata
882 module couldn't be imported and \N escapes were present.
883
884- Issue #4348: Some bytearray methods returned that didn't cause any change to
885 the bytearray, returned the same bytearray instead of a copy.
886
887- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
888
889- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
890
891- Issue #4048: The parser module now correctly validates relative imports.
892
893- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

895
896- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
897 method does not return iterators for the 4th and 5th items.
898
899- Issue #4209: Enabling unicode_literals and the print_function in the same
900 __future__ import didn't work.
901
902- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
903 returned a path longer than MAX_PATH. (But It's doubtful this code path is
904 really executed because I cannot move to such directory on win2k)
905
906- Issue #4069: When set.remove(element) is used with a set element, the element
907 is temporarily replaced with an equivalent frozenset. But the eventual
908 KeyError would always report the empty frozenset([]) as the missing key. Now
909 it correctly refers to the initial element.
910
911- Fixed C99 style comments in several files. Python is now C89 compatible
912 again.

1040 AttributeError instead of RuntimeError, depending in which C API call
1041 exactly the recursion limit is exceeded. Consequently, both exception types
1042 are caught and silenced.

1058
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001059- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1060
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001061- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1062 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1063 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1064 ``printf`` function, whereas PyString_FromFormat has an independent
1065 implementation and uses "%zd" on all platforms for size_t values.
1066 This makes a difference on win64, where ``printf`` needs "%Id" to display
1067 64bit values.
1068
Benjamin Peterson97179b02008-09-09 20:55:01 +00001069- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1070 error.
1071
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001072- Issue #3777: long() applied to a float object now always return a long
1073 object; previously an int would be returned for small values. the __long__
1074 method is allowed to return either an int or a long, but the behaviour of
1075 float objects should not change to respect backward compatibility.
1076
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001077- Issue #3751: str.rpartition would perform a left-partition when called with
1078 a unicode argument.
1079
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001080- Issue #3683: Fix compilation when --without-threads is given.
1081
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001082- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001083 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001084 was correctly parsed but parsing of subsequent arguments failed.
1085
Vinay Sajip35e3b032008-09-01 14:33:59 +00001086- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001087 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1088 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1089 when given a tuple of classes as second argument, were looking up
1090 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1091 type object.
1092
Neal Norwitz18aa3882008-08-24 05:04:52 +00001093- Fix crashes on memory allocation failure found with failmalloc.
1094
1095- Fix memory leaks found with valgrind and update suppressions file.
1096
1097- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1098
1099- Fix problem using wrong name in decimal module reported by pychecker.

Christian Heimes7d4c3172008-08-22 19:47:25 +00001101- Silenced another compiler warning about a used but not defined
1102 function 'stringlib_contains_obj'.

1108 library targets in the Makefile.
1109
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001110- Issue #1204: The configure script now tests for additional libraries
1111 that may be required when linking against readline. This fixes issues
1112 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001129- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1130 silent misbehaviour when a single instance is nested in multiple
1131 with statements, or when the methods are invoked in the wrong order.
1132
Vinay Sajip844f7412008-09-09 13:42:08 +00001133- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1134
Nick Coghland2e09382008-09-11 12:11:06 +00001135- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001136 return a list or None rather than a custom object.
1137
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001138- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1162 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1163 for catch_warnings() also led to an improvement in the raising of a
1164 DeprecationWarning related to warnings.warn_explicit().
1165
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001166- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001227What's New in Python 2.6 beta 3?
1228================================

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001231
1232Core and Builtins
1233-----------------
1234
Guido van Rossumf8402962008-08-20 15:01:50 +00001235- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1236 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1237 extensions do not automatically benefit from the class attribute
1238 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1239 to their tp_flags field if they care. This is a backwards
1240 compatibility feature; in 3.0, all types will use the cache by
1241 default.
1242
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001243- Keyword arguments can now follow starred arguments. (``f(a, *args,
1244 keyword=23)`` is now valid syntax.)
1245
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001246- ctypes function pointers that are COM methods have a boolean True
1247 value again.
1248
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001249- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1250 by denying s# to parse objects that have a releasebuffer procedure,
1251 and introducing s*.
1252
Georg Brandl1e13ea92008-08-11 09:07:59 +00001253- Issue #3537: Fix an assertion failure when an empty but presized dict
1254 object was stored in the freelist.
1255
Mark Dickinsonb6467572008-08-04 21:30:09 +00001256- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1257 ValueError consistently across platforms.
1258
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001259- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1260 (64bit Unix, for example), unichr() would truncate its argument and return
1261 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1262
Neal Norwitze7d8be82008-07-31 17:17:14 +00001263- Apply security patches from Apple.
1264
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001265- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1266 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1267
Antoine Pitrou92f82162008-07-25 22:22:08 +00001268- Issue #1819: function calls with several named parameters are now on
1269 average 35% faster (as measured by pybench).
1270
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001271- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1272 the python debugger steps into a class statement: the free variables (local
1273 variables defined in an outer scope) would be deleted from the outer scope.
1274
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001275- Issue #2620: Overflow checking when allocating or reallocating memory
1276 was not always being done properly in some python types and extension
1277 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1278 all been updated to perform better checks and places in the code that
1279 would previously leak memory on the error path when such an allocation
1280 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001285- Issue #3612: Added some missing basic types in ctypes.wintypes.
1286
Benjamin Petersone977ad42008-08-20 01:42:01 +00001287- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1288 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1289
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001290- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1291 version reported by these tools does not necessarily follow the python
1292 version numbering scheme, so the module is less strict when parsing it.
1293
Nick Coghlanf70385a2008-08-18 12:42:46 +00001294- Issue #2235: Added Py3k warnings for types which will become unhashable
1295 under the stricter __hash__ inheritance rules in 3.0. Several types
1296 which did not meet the rules for hash invariants and were already
1297 unhashable in 3.0 have now been explicitly flagged as unhashable in
1298 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1299 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1300
Brett Cannon88f801d2008-08-18 00:46:22 +00001301- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1302 imported into the module but exposed as part of the module's API.
1303
Brett Cannon7b96f072008-08-18 00:41:11 +00001304- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1305
Brett Cannon46225e72008-08-18 00:36:52 +00001306- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1414
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001415- Issue #643841: The language reference now provides more detailed

1427-----------------
1428
Georg Brandl3e483f62008-07-16 22:57:41 +00001429- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1430 its methods now allow for items objects that can be converted to
1431 an integer using operator.index().
1432
Mark Dickinson64b7e502008-07-16 09:40:03 +00001433- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1434 produced a ValueError instead of giving the correct float.
1435
Eric Smitha5fa5a22008-07-16 00:11:49 +00001436- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1437 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1438
Mark Dickinson7103aa42008-07-15 19:08:33 +00001439- Issue #3008: the float type has a new instance method 'float.hex'
1440 and a new class method 'float.fromhex' to convert floating-point
1441 numbers to and from hexadecimal strings, respectively.
1442
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001443- Issue #2235: __hash__ is once again inherited by default. To allow
1444 collections.Hashable to remain meaningful in the presence of the
1445 default hash implementation (object.__hash__), it is now possible
1446 to explicit block inheritance of hash by setting __hash__=None at
1447 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1448 level.
1449
Nick Coghlanb028f502008-07-13 14:52:36 +00001450- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1451 the parent module cannot be found while performing an absolute import.
1452 This means that an incorrectly defined __package__ attribute will
1453 now only prevent relative imports in that module rather than causing
1454 all imports from that module to fail.
1455
Nick Coghlan14ff9942008-07-08 14:21:42 +00001456- Issue #2517: Allow unicode messages in Exceptions again by correctly

1466 another thread's dictionary.
1467
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001468- Issue #3004: Minor change to slice.indices(): the start and stop
1469 arguments are now treated identically, making the behaviour easier
1470 to describe and understand. For example, slice(None, -10,
1471 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1472 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1473 10, -1).
1474
Georg Brandl278fc502008-07-19 12:46:12 +00001475- Issue #3219: Calling a function with repeated keyword arguments,
1476 f(a=2, a=23), would not cause a syntax error. This was a regression
1477 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00001479- Issue #2862: Make int and float freelist management consistent with
1480 other freelists. Changes their CompactFreeList apis into

1487 api functions without holding the GIL, which could lead to a fatal
1488 error when they failed.
1489
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001490- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001515- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1516 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001517 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001518 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001534- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1926 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001927 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001928
1929 This is controlled by the configure argument ``--with-universal-archs``:
1930
1931 - ``--with-universal-archs=all``: install 4-way universal
1932
1933 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1934
1935 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1936
1937 This option should be used in combination with ``--enable-universalsdk=``.
1938
1939 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 +00001989- Issue #1631171: Re-implement the 'warnings' module in C (the
1990 original Python code has been kept as backup). This will allow for
1991 using the 'warning's machinery in such places as the parser where
1992 use of pure Python code is not possible. Both the ``showarning()``
1993 and ``formatwarning()`` gain an optional 'line' argument which is
1994 not called by default for backwards-compatibility reasons. Setting
1995 ``warnings.showwarning()`` to an implementation that lacks support
1996 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002059- Issue #2550: The approach used by client/server code for obtaining
2060 ports to listen on in network-oriented tests has been refined in an
2061 effort to facilitate running multiple instances of the entire
2062 regression test suite in parallel without issue.
2063 test_support.bind_port() has been fixed such that it will always
2064 return a unique port -- which wasn't always the case with the
2065 previous implementation, especially if socket options had been set
2066 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2067 new implementation of bind_port() will actually raise an exception
2068 if it is passed an AF_INET/SOCK_STREAM socket with either the
2069 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2070 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2071 the socket it's been passed. This currently only applies to
2072 Windows. This option prevents any other sockets from binding to the
2073 host/port we've bound to, thus removing the possibility of the
2074 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2075 when a second SOCK_STREAM socket binds and accepts to a host/port
2076 that's already been bound by another socket. The optional preferred
2077 port parameter to bind_port() has been removed. Under no
2078 circumstances should tests be hard coding ports!
2079
2080 test_support.find_unused_port() has also been introduced, which will
2081 pass a temporary socket object to bind_port() in order to obtain an
2082 unused port. The temporary socket object is then closed and
2083 deleted, and the port is returned. This method should only be used
2084 for obtaining an unused port in order to pass to an external program
2085 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2086 a parameter to a server-oriented class that doesn't give you direct
2087 access to the underlying socket used.
2088
2089 Finally, test_support.HOST has been introduced, which should be used
2090 for the host argument of any relevant socket calls (i.e. bind and
2091 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002092
2093 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002094 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002095 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2096 test_asynchat and test_socket_ssl.
2097
Georg Brandl3ee81df2008-05-17 18:14:43 +00002098 It is now possible for multiple instances of the regression test
2099 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002153- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002154 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2155 Plane. This affected raw unicode literals and the
2156 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2157 this case, like normal unicode literals and the 'unicode-escape'
2158 codec.

2367
Fred Drakea8ee94b2008-03-01 02:45:07 +00002368- Issue #2051: pyc and pyo files are no longer created with permission

Christian Heimes5224d282008-02-23 15:01:05 +00002374
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002375- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002376 issue 215555 for a discussion.
2377
Eric Smitha73fbe72008-02-23 03:09:44 +00002378- Added the future_builtins module, which contains hex() and oct().
2379 These are the PEP 3127 version of these functions, designed to be
2380 compatible with the hex() and oct() builtins from Python 3.0. They
2381 differ slightly in their output formats from the existing, unchanged
2382 Python 2.6 builtins. The expected usage of the future_builtins
2383 module is:
2384 from future_builtins import hex, oct
2385
Eric Smith7ef40bf2008-02-20 23:34:22 +00002386- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2387 exponents for exponents with absolute value < 100. Follows C99
2388 standard. This is a change on Windows, which would use 3 digits.
2389 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2390 so that any alterations it does to the resulting string will be
2391 available in stringlib/formatter.h (for float.__format__).
2392
Eric Smith5a3c1352008-02-19 13:21:56 +00002393- Implemented PEP 3101, Advanced String Formatting. This adds a new
2394 builtin format(); a format() method for str and unicode; a
2395 __format__() method to object, str, unicode, int, long, float, and
2396 datetime; the class string.Formatter; and the C API
2397 PyObject_Format().
2398
Georg Brandl3ee81df2008-05-17 18:14:43 +00002399- Fixed several potential crashes, all caused by specially crafted
2400 __del__ methods exploiting objects in temporarily inconsistent

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002403- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002404 prevent a possible crash: an Abstract Base Class would try to access
2405 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002406
Georg Brandl3ee81df2008-05-17 18:14:43 +00002407- Fixed repr() and str() of complex numbers with infinity or nan as
2408 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002409
Georg Brandl3ee81df2008-05-17 18:14:43 +00002410- Clear all free lists during a gc.collect() of the highest generation
2411 in order to allow pymalloc to free more arenas. Python may give back
2412 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002413
Georg Brandl3ee81df2008-05-17 18:14:43 +00002414- Issue #2045: Fix an infinite recursion triggered when printing a
2415 subclass of collections.defaultdict, if its default_factory is set
2416 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002417
Christian Heimesf75dbef2008-02-08 00:11:31 +00002418- Fixed a minor memory leak in dictobject.c. The content of the free
2419 list was not freed on interpreter shutdown.
2420
Georg Brandl3ee81df2008-05-17 18:14:43 +00002421- Limit free list of method and builtin function objects to 256
2422 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002423
Georg Brandl3ee81df2008-05-17 18:14:43 +00002424- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2425 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002426 to compact the internal free lists of pre-allocted ints and floats.
2427
Georg Brandl3ee81df2008-05-17 18:14:43 +00002428- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2429 calls. Python expected the return type int but the fork familie
2430 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002431
Georg Brandl3ee81df2008-05-17 18:14:43 +00002432- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2433 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002444- Patch #1473257: generator objects gain a gi_code attribute. This is
2445 the same object as the func_code attribute of the function that
2446 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002447
Georg Brandl3ee81df2008-05-17 18:14:43 +00002448- Issue #1920: "while 0" statements were completely removed by the
2449 compiler, even in the presence of an "else" clause, which is
2450 supposed to be run when the condition is false. Now the compiler
2451 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002452
Guido van Rossumeead05f2008-01-24 18:21:02 +00002453- A few crashers fixed: weakref_in_del.py (issue #1377858);
2454 loosing_dict_ref.py (issue #1303614, test67.py);
2455 borrowed_ref_[34].py (not in tracker).
2456
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002457- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002458 suppressed while an extension is loaded by calling SetErrorMode in
2459 dynload_win.c. The error is still reported properly.
2460
Georg Brandl3ee81df2008-05-17 18:14:43 +00002461- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002462 several extension methods and modules do not work without unicode
2463 support.
2464
Georg Brandl26543b12008-01-21 18:36:51 +00002465- Issue #1882: when compiling code from a string, encoding cookies in the
2466 second line of code were not always recognized correctly.
2467
Georg Brandl14404b62008-01-19 19:27:05 +00002468- Issue #1679: "0x" was taken as a valid integer literal.
2469
Georg Brandl6caad7d2008-01-26 14:19:22 +00002470- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002471 added.
2472
Christian Heimesc94e2b52008-01-14 04:13:37 +00002473- sys.float_info / PyFloat_GetInfo: The floating point information
2474 object was converted from a dict to a specialized structseq object.
2475
Georg Brandl3ee81df2008-05-17 18:14:43 +00002476- Patch #1816: Added sys.flags structseq. It exposes the status of
2477 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002478
Georg Brandl3ee81df2008-05-17 18:14:43 +00002479- Objects/structseq.c: Implemented new structseq representation. The
2480 patch makes structseqs (e.g. the return value of os.stat) more
2481 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002482
Georg Brandl3ee81df2008-05-17 18:14:43 +00002483- Patch #1700288: added a type attribute cache that caches method
2484 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002485
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002486- Bug #1776: __import__() no longer accepts filenames on any platform.
2487 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002488

2492 envvar and sys.dont_write_bytecode attribute. All these can be set
2493 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002494
Georg Brandl3ee81df2008-05-17 18:14:43 +00002495- Improve some exception messages when Windows fails to load an
2496 extension module. Now we get for example '%1 is not a valid Win32
2497 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002498

Christian Heimes0a8143f2007-12-18 23:22:54 +00002504- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002505 and INF. float("nan"), float("inf") and float("-inf") now work on
2506 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002507
Georg Brandl3ee81df2008-05-17 18:14:43 +00002508- Compiler now generates simpler and faster code for dictionary
2509 literals. The oparg for BUILD_MAP now indicates an estimated
2510 dictionary size. There is a new opcode, STORE_MAP, for adding
2511 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002540- Patch #1739468: Directories and zipfiles containing a __main__.py
2541 file can now be directly executed by passing their name to the
2542 interpreter. The directory/zipfile is automatically inserted as the
2543 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002544
Georg Brandl3ee81df2008-05-17 18:14:43 +00002545- Issue #1265: Fix a problem with sys.settrace, if the tracing
2546 function uses a generator expression when at the same time the
2547 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002548
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002549- sets and frozensets now have an isdisjoint() method.
2550

2552
Neal Norwitz44f326e2007-10-05 05:29:17 +00002553- Fix warnings found by the new version of the Coverity checker.
2554
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555- The enumerate() builtin function is no longer bounded to sequences
2556 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2557 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002558
Georg Brandl3ee81df2008-05-17 18:14:43 +00002559- Issue #1686386: Tuple's tp_repr did not take into account the
2560 possibility of having a self-referential tuple, which is possible
2561 from C code. Nor did object's tp_str consider that a type's tp_str
2562 could do something that could lead to an inifinite recursion.
2563 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2564 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002565
Georg Brandl3ee81df2008-05-17 18:14:43 +00002566- Issue #1164: It was possible to trigger deadlock when using the
2567 'print' statement to write to a file since the GIL was not released
2568 as needed. Now PyObject_Print() does the right thing along with
2569 various tp_print implementations of the built-in types and those in
2570 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002571
Georg Brandl3ee81df2008-05-17 18:14:43 +00002572- Issue #1147: Exceptions were directly allowing string exceptions in
2573 their throw() method even though string exceptions no longer
2574 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002575
Georg Brandl3ee81df2008-05-17 18:14:43 +00002576- Issue #1096: Prevent a segfault from getting the repr of a very
2577 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002578
Brett Cannon1e534b52007-09-07 04:18:30 +00002579- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002580 PyObject_Call() never calling back out to Python code to trigger
2581 recursion depth updates/checks. Required the creation of a static
2582 RuntimeError instance in case normalizing an exception put the
2583 recursion check value past its limit. Fixes crashers
2584 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002585

Neal Norwitz0ac60192007-05-27 04:08:54 +00002599- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002600 __*__ attributes. (Some already existed, e.g., __doc__ and
2601 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002602
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002603- Add -3 option to the interpreter to warn about features that are
2604 deprecated and will be changed/removed in Python 3.0.
2605
Georg Brandl2134e752007-05-21 20:34:16 +00002606- Patch #1686487: you can now pass any mapping after '**' in function
2607 calls.
2608
Collin Winter62903052007-05-18 23:11:24 +00002609- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002610 "except E as target:". This is to provide forwards compatibility
2611 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002612
Brett Cannon229cee22007-05-05 01:34:02 +00002613- Deprecate BaseException.message as per PEP 352.
2614
Georg Brandl3ee81df2008-05-17 18:14:43 +00002615- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002616 inherited from a builtin base.
2617
Vinay Sajip8549ce32007-05-06 17:53:37 +00002618- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002619 setting a plain string, ie don't expand to single letter identifiers.
2620
Raymond Hettinger13936692007-04-11 18:40:58 +00002621- Request #1191699: Slices can now be pickled.
2622
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002623- Request #1193128: str.translate() now allows a None argument for
2624 translations that only remove characters without re-mapping the
2625 remaining characters.
2626
Georg Brandl5cb76c12007-03-21 09:00:39 +00002627- Patch #1682205: a TypeError while unpacking an iterable is no longer
2628 masked by a generic one with the message "unpack non-sequence".
2629
Neal Norwitzaa754b72007-03-21 06:39:48 +00002630- Remove unused file Python/fmod.c.
2631
Guido van Rossum143b5642007-03-23 04:58:42 +00002632- Bug #1683368: The object.__init__() and object.__new__() methods are
2633 now stricter in rejecting excess arguments. The only time when
2634 either allows excess arguments is when it is not overridden and the
2635 other one is. For backwards compatibility, when both are
2636 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002637 warning later). Also, type.__init__() insists on the same signature
2638 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002639
Georg Brandl3ee81df2008-05-17 18:14:43 +00002640- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2641 object to complex using its __complex__() method before falling back
2642 to the __float__() method. Therefore, the functions in the cmath

Georg Brandl3ee81df2008-05-17 18:14:43 +00002666 its argument, if it exists. If not, it will work like before. This
2667 allows customizing the output of dir() in the presence of a
2668 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002680- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00002750- Bug #1545497: when given an explicit base, int() did ignore NULs
2751 embedded in the string to convert.
2752
Georg Brandl846f73a2006-10-08 07:11:54 +00002753- Bug #1569998: break inside a try statement (outside a loop) is now
2754 recognized and rejected.

Georg Brandl4e933132006-09-06 20:05:58 +00002783- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002801 generator expressions (x for x, in ... ) works again. Fixing this
2802 problem required changing the .pyc magic number. This means that
2803 .pyc files generated before 2.5c2 will be regenerated.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003616 that the SMTP.starttls() caller no longer needs to call ehlo()
3617 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003618 does not claim to support starttls. Adds the
3619 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3620 Fenner.

3700 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3701 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003718 time so that opening a database previously created with the DB_DUP
3719 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3720 opens. Specifically: dictionary assignment to a DB object will
3721 replace all values for a given key when the database allows
3722 duplicate values. DB users should use DB.put(k, v) when they want
3723 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003724

3730 characters with ASCII value less than 32. Also, it correctly quotes
3731 dots only if they occur on a single line, as opposed to the previous
3732 behavior of quoting dots if they are the second character of any
3733 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003734
