Georg Brandld2094602008-12-05 08:51:30 +000087 method on file objects with closefd=False. The file descriptor is still

301 302 conformant loader) will now work correctly in most cases (they
302 are still subject to the constraints that exist for all code running

462What's New in Python 2.6.1
463==========================
464
465*Release date: 04-Dec-2008*
466
467Core and Builtins
468-----------------
469
470- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
471 interpreter to abort ("Fatal Python error: Could not reset the stack!")
472 instead of throwing a MemoryError.
473
474- Issue #4367: Python would segfault during compiling when the unicodedata
475 module couldn't be imported and \N escapes were present.
476
477- Issue #4348: Some bytearray methods returned that didn't cause any change to
478 the bytearray, returned the same bytearray instead of a copy.
479
480- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
481
482- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
483
484- Issue #4048: The parser module now correctly validates relative imports.
485
486- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
487 exec statement.
488
489- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
490 method does not return iterators for the 4th and 5th items.
491
492- Issue #4209: Enabling unicode_literals and the print_function in the same
493 __future__ import didn't work.
494
495- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
496 returned a path longer than MAX_PATH. (But It's doubtful this code path is
497 really executed because I cannot move to such directory on win2k)
498
499- Issue #4069: When set.remove(element) is used with a set element, the element
500 is temporarily replaced with an equivalent frozenset. But the eventual
501 KeyError would always report the empty frozenset([]) as the missing key. Now
502 it correctly refers to the initial element.
503
504- Fixed C99 style comments in several files. Python is now C89 compatible
505 again.

653
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000654- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
655 PyString_FromFormat or PyErr_Format to display size_t values. The macro
656 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
657 ``printf`` function, whereas PyString_FromFormat has an independent

681 mechanism. In the process, fix a bug where isinstance() and issubclass(),
682 when given a tuple of classes as second argument, were looking up
683 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
684 type object.

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

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000820What's New in Python 2.6 beta 3?
821================================
822
Barry Warsaw07a4a382008-08-21 01:15:08 +0000823*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000824
825Core and Builtins
826-----------------
827
Guido van Rossumf8402962008-08-20 15:01:50 +0000828- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
829 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
830 extensions do not automatically benefit from the class attribute
831 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
832 to their tp_flags field if they care. This is a backwards
833 compatibility feature; in 3.0, all types will use the cache by
834 default.
835
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000836- Keyword arguments can now follow starred arguments. (``f(a, *args,
837 keyword=23)`` is now valid syntax.)
838
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000839- ctypes function pointers that are COM methods have a boolean True
840 value again.
841
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000842- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
843 by denying s# to parse objects that have a releasebuffer procedure,
844 and introducing s*.
845
Georg Brandl1e13ea92008-08-11 09:07:59 +0000846- Issue #3537: Fix an assertion failure when an empty but presized dict
847 object was stored in the freelist.
848
Mark Dickinsonb6467572008-08-04 21:30:09 +0000849- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
850 ValueError consistently across platforms.
851
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000852- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
853 (64bit Unix, for example), unichr() would truncate its argument and return
854 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
855
Neal Norwitze7d8be82008-07-31 17:17:14 +0000856- Apply security patches from Apple.
857
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000858- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
859 PyErr_ExceptionMatches returns 0 when an exception occurs there.
860
Antoine Pitrou92f82162008-07-25 22:22:08 +0000861- Issue #1819: function calls with several named parameters are now on
862 average 35% faster (as measured by pybench).
863
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000864- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
865 the python debugger steps into a class statement: the free variables (local
866 variables defined in an outer scope) would be deleted from the outer scope.
867
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000868- Issue #2620: Overflow checking when allocating or reallocating memory
869 was not always being done properly in some python types and extension
870 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
871 all been updated to perform better checks and places in the code that
872 would previously leak memory on the error path when such an allocation
873 failed have been fixed.

882
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000883- Issue #2234: distutils failed for some versions of the cygwin compiler. The
884 version reported by these tools does not necessarily follow the python
885 version numbering scheme, so the module is less strict when parsing it.
886
Nick Coghlanf70385a2008-08-18 12:42:46 +0000887- Issue #2235: Added Py3k warnings for types which will become unhashable
888 under the stricter __hash__ inheritance rules in 3.0. Several types
889 which did not meet the rules for hash invariants and were already
890 unhashable in 3.0 have now been explicitly flagged as unhashable in
891 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
892 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
893
Brett Cannon88f801d2008-08-18 00:46:22 +0000894- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

902
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000903- Issue #3575: Incremental decoder's decode function now takes bytearray
904 by using 's*' instead of 't#'.
905
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000906- Issue #2222: Fixed reference leak when occured os.rename()
907 fails unicode conversion on 2nd parameter. (windows only)
908
Facundo Batista94f243a2008-08-17 03:38:39 +0000909- Issue 2464. urllib2 now supports a malformation in the URL received
910 in a redirect.
911
Brett Cannonabe423e2008-08-16 21:47:07 +0000912- Silence the DeprecationWarning raised when importing mimetools in

Brett Cannonabe423e2008-08-16 21:47:07 +0000914
Facundo Batistaeb90b782008-08-16 14:44:07 +0000915- Issue #2776: fixed small issue when handling an URL with double slash
916 after a 302 response in the case of not going through a proxy.
917
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000918- Issue #2676: in the email package, content-type parsing was hanging on
919 pathological input because of quadratic or exponential behaviour of a
920 regular expression.
921
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000922- Issue #3476: binary buffered reading through the new "io" library is now
923 thread-safe.
924
Brett Cannonbf3157b2008-08-14 05:00:03 +0000925- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
926 since mimetools itself is deprecated. Because modules are cached, all
927 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
928
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000929- Issue #3134: shutil referenced undefined WindowsError symbol.
930
Robert Schuppenies14646332008-08-10 11:01:53 +0000931- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
932 menu entries were not deleted.
933
Brett Cannon83e81842008-08-09 23:30:55 +0000934- Copied the implementation of reduce() to _functools.reduce() to have a
935 version that did not raise a DeprecationWarning under -3.
936
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000937- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
938 a MemoryError rather than silently stop the iteration.
939
Guido van Rossum59ce9012008-08-09 14:55:34 +0000940- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
941 to _sre.compile() will now be rejected. This should not affect anybody
942 since the re.compile() function never generates invalid re-bytecode.
943
Skip Montanaroa032bf42008-08-08 22:52:51 +0000944- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
945 upon first access it can be automatically initialized from the csv file if
946 it wasn't initialized during instantiation.
947
Brett Cannon3aa2a492008-08-06 22:28:09 +0000948- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
949 the reload() built-in has been removed.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001014What's New in Python 2.6 beta 2?
1015================================
1016
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001017*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001019Core and Builtins
1020-----------------
1021
Georg Brandl3e483f62008-07-16 22:57:41 +00001022- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1023 its methods now allow for items objects that can be converted to
1024 an integer using operator.index().
1025
Mark Dickinson64b7e502008-07-16 09:40:03 +00001026- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1027 produced a ValueError instead of giving the correct float.
1028
Eric Smitha5fa5a22008-07-16 00:11:49 +00001029- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1030 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1031
Mark Dickinson7103aa42008-07-15 19:08:33 +00001032- Issue #3008: the float type has a new instance method 'float.hex'
1033 and a new class method 'float.fromhex' to convert floating-point
1034 numbers to and from hexadecimal strings, respectively.
1035
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001036- Issue #2235: __hash__ is once again inherited by default. To allow
1037 collections.Hashable to remain meaningful in the presence of the
1038 default hash implementation (object.__hash__), it is now possible
1039 to explicit block inheritance of hash by setting __hash__=None at
1040 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1041 level.
1042
Nick Coghlanb028f502008-07-13 14:52:36 +00001043- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1044 the parent module cannot be found while performing an absolute import.
1045 This means that an incorrectly defined __package__ attribute will
1046 now only prevent relative imports in that module rather than causing
1047 all imports from that module to fail.
1048
Nick Coghlan14ff9942008-07-08 14:21:42 +00001049- Issue #2517: Allow unicode messages in Exceptions again by correctly
1050 bypassing the instance dictionary when looking up __unicode__ on
1051 new-style classes.

1054 set to a custom object whose write() method happens to install
1055 another file in sys.stdout.
1056
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001057- Issue #3088: Corrected a race condition in classes derived from
1058 threading.local: the first member set by a thread could be saved in
1059 another thread's dictionary.
1060
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001061- Issue #3004: Minor change to slice.indices(): the start and stop
1062 arguments are now treated identically, making the behaviour easier
1063 to describe and understand. For example, slice(None, -10,
1064 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1065 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1066 10, -1).
1067
Georg Brandl278fc502008-07-19 12:46:12 +00001068- Issue #3219: Calling a function with repeated keyword arguments,
1069 f(a=2, a=23), would not cause a syntax error. This was a regression
1070 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001071
Georg Brandl278fc502008-07-19 12:46:12 +00001072- Issue #2862: Make int and float freelist management consistent with
1073 other freelists. Changes their CompactFreeList apis into
1074 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001079- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1080 api functions without holding the GIL, which could lead to a fatal
1081 error when they failed.
1082
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001083- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001108- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1109 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001110 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001111 content-length. The problem had been corrected in the 2.4 branch, but never
1112 merged into trunk.
1113

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001127- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1128 handling is now the same as that of other special attributes like __name__).
1129
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001130- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00001582- Issue #1631171: Re-implement the 'warnings' module in C (the
1583 original Python code has been kept as backup). This will allow for
1584 using the 'warning's machinery in such places as the parser where
1585 use of pure Python code is not possible. Both the ``showarning()``
1586 and ``formatwarning()`` gain an optional 'line' argument which is
1587 not called by default for backwards-compatibility reasons. Setting
1588 ``warnings.showwarning()`` to an implementation that lacks support
1589 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001631- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001632 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001652- Issue #2550: The approach used by client/server code for obtaining
1653 ports to listen on in network-oriented tests has been refined in an
1654 effort to facilitate running multiple instances of the entire
1655 regression test suite in parallel without issue.
1656 test_support.bind_port() has been fixed such that it will always
1657 return a unique port -- which wasn't always the case with the
1658 previous implementation, especially if socket options had been set
1659 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1660 new implementation of bind_port() will actually raise an exception
1661 if it is passed an AF_INET/SOCK_STREAM socket with either the
1662 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1663 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1664 the socket it's been passed. This currently only applies to
1665 Windows. This option prevents any other sockets from binding to the
1666 host/port we've bound to, thus removing the possibility of the
1667 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1668 when a second SOCK_STREAM socket binds and accepts to a host/port
1669 that's already been bound by another socket. The optional preferred
1670 port parameter to bind_port() has been removed. Under no
1671 circumstances should tests be hard coding ports!
1672
1673 test_support.find_unused_port() has also been introduced, which will
1674 pass a temporary socket object to bind_port() in order to obtain an
1675 unused port. The temporary socket object is then closed and
1676 deleted, and the port is returned. This method should only be used
1677 for obtaining an unused port in order to pass to an external program
1678 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1679 a parameter to a server-oriented class that doesn't give you direct
1680 access to the underlying socket used.
1681
1682 Finally, test_support.HOST has been introduced, which should be used
1683 for the host argument of any relevant socket calls (i.e. bind and
1684 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001685
1686 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001687 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001688 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1689 test_asynchat and test_socket_ssl.
1690
Georg Brandl3ee81df2008-05-17 18:14:43 +00001691 It is now possible for multiple instances of the regression test
1692 suite to run in parallel without issue.

1960
Fred Drakea8ee94b2008-03-01 02:45:07 +00001961- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001962 644. The mode is now inherited from the py file.

1970
Eric Smitha73fbe72008-02-23 03:09:44 +00001971- Added the future_builtins module, which contains hex() and oct().
1972 These are the PEP 3127 version of these functions, designed to be
1973 compatible with the hex() and oct() builtins from Python 3.0. They
1974 differ slightly in their output formats from the existing, unchanged
1975 Python 2.6 builtins. The expected usage of the future_builtins
1976 module is:
1977 from future_builtins import hex, oct
1978
Eric Smith7ef40bf2008-02-20 23:34:22 +00001979- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1980 exponents for exponents with absolute value < 100. Follows C99
1981 standard. This is a change on Windows, which would use 3 digits.
1982 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1983 so that any alterations it does to the resulting string will be
1984 available in stringlib/formatter.h (for float.__format__).
1985
Eric Smith5a3c1352008-02-19 13:21:56 +00001986- Implemented PEP 3101, Advanced String Formatting. This adds a new
1987 builtin format(); a format() method for str and unicode; a
1988 __format__() method to object, str, unicode, int, long, float, and
1989 datetime; the class string.Formatter; and the C API
1990 PyObject_Format().
1991
Georg Brandl3ee81df2008-05-17 18:14:43 +00001992- Fixed several potential crashes, all caused by specially crafted
1993 __del__ methods exploiting objects in temporarily inconsistent
1994 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001995
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001996- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001997 prevent a possible crash: an Abstract Base Class would try to access
1998 a slot on a registered virtual subclass.

2005 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002006
Georg Brandl3ee81df2008-05-17 18:14:43 +00002007- Issue #2045: Fix an infinite recursion triggered when printing a

2018 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002019 to compact the internal free lists of pre-allocted ints and floats.
2020
Georg Brandl3ee81df2008-05-17 18:14:43 +00002021- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2022 calls. Python expected the return type int but the fork familie
2023 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002037- Patch #1473257: generator objects gain a gi_code attribute. This is
2038 the same object as the func_code attribute of the function that
2039 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002040
Georg Brandl3ee81df2008-05-17 18:14:43 +00002041- Issue #1920: "while 0" statements were completely removed by the
2042 compiler, even in the presence of an "else" clause, which is
2043 supposed to be run when the condition is false. Now the compiler
2044 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002045

Christian Heimes288e89a2008-01-18 18:24:07 +00002064 added.
2065
Christian Heimesc94e2b52008-01-14 04:13:37 +00002066- sys.float_info / PyFloat_GetInfo: The floating point information
2067 object was converted from a dict to a specialized structseq object.
2068
Georg Brandl3ee81df2008-05-17 18:14:43 +00002069- Patch #1816: Added sys.flags structseq. It exposes the status of
2070 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002071
Georg Brandl3ee81df2008-05-17 18:14:43 +00002072- Objects/structseq.c: Implemented new structseq representation. The
2073 patch makes structseqs (e.g. the return value of os.stat) more
2074 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002075
Georg Brandl3ee81df2008-05-17 18:14:43 +00002076- Patch #1700288: added a type attribute cache that caches method
2077 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002078
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002079- Bug #1776: __import__() no longer accepts filenames on any platform.
2080 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002081
Georg Brandlaed6c662008-01-07 17:25:53 +00002082- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2083
Georg Brandl3ee81df2008-05-17 18:14:43 +00002084- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2085 envvar and sys.dont_write_bytecode attribute. All these can be set
2086 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002087
Georg Brandl3ee81df2008-05-17 18:14:43 +00002088- Improve some exception messages when Windows fails to load an
2089 extension module. Now we get for example '%1 is not a valid Win32
2090 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002091
Georg Brandl3ee81df2008-05-17 18:14:43 +00002092- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002094- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2095 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002096
Christian Heimes0a8143f2007-12-18 23:22:54 +00002097- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002098 and INF. float("nan"), float("inf") and float("-inf") now work on
2099 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002100
Georg Brandl3ee81df2008-05-17 18:14:43 +00002101- Compiler now generates simpler and faster code for dictionary
2102 literals. The oparg for BUILD_MAP now indicates an estimated
2103 dictionary size. There is a new opcode, STORE_MAP, for adding
2104 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002108- Issue #1620: New property decorator syntax was modifying the
2109 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002110
Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Issue #1538: Avoid copying string in split/rsplit if the split char
2112 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002113
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002114- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002115 SystemError.
2116
Nick Coghlanef01d822007-12-03 12:55:17 +00002117- PEP 366: Allow explicit relative imports when executing modules

2122 running, and if the deallocation of its frames somehow calls the
2123 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002124

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00002128 attribute of an empty cell object.
2129
Georg Brandl3ee81df2008-05-17 18:14:43 +00002130- Issue #1460: The utf-7 incremental decoder did not accept truncated
2131 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002132
Georg Brandl3ee81df2008-05-17 18:14:43 +00002133- Patch #1739468: Directories and zipfiles containing a __main__.py
2134 file can now be directly executed by passing their name to the
2135 interpreter. The directory/zipfile is automatically inserted as the
2136 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002137
Georg Brandl3ee81df2008-05-17 18:14:43 +00002138- Issue #1265: Fix a problem with sys.settrace, if the tracing
2139 function uses a generator expression when at the same time the
2140 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002141
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002142- sets and frozensets now have an isdisjoint() method.
2143
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002144- optimize the performance of builtin.sum().
2145
Neal Norwitz44f326e2007-10-05 05:29:17 +00002146- Fix warnings found by the new version of the Coverity checker.
2147
Georg Brandl3ee81df2008-05-17 18:14:43 +00002148- The enumerate() builtin function is no longer bounded to sequences
2149 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2150 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002151
Georg Brandl3ee81df2008-05-17 18:14:43 +00002152- Issue #1686386: Tuple's tp_repr did not take into account the
2153 possibility of having a self-referential tuple, which is possible
2154 from C code. Nor did object's tp_str consider that a type's tp_str
2155 could do something that could lead to an inifinite recursion.
2156 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2157 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002158
Georg Brandl3ee81df2008-05-17 18:14:43 +00002159- Issue #1164: It was possible to trigger deadlock when using the
2160 'print' statement to write to a file since the GIL was not released
2161 as needed. Now PyObject_Print() does the right thing along with
2162 various tp_print implementations of the built-in types and those in
2163 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002164
Georg Brandl3ee81df2008-05-17 18:14:43 +00002165- Issue #1147: Exceptions were directly allowing string exceptions in
2166 their throw() method even though string exceptions no longer
2167 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002168
Georg Brandl3ee81df2008-05-17 18:14:43 +00002169- Issue #1096: Prevent a segfault from getting the repr of a very
2170 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002171
Brett Cannon1e534b52007-09-07 04:18:30 +00002172- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002173 PyObject_Call() never calling back out to Python code to trigger
2174 recursion depth updates/checks. Required the creation of a static
2175 RuntimeError instance in case normalizing an exception put the
2176 recursion check value past its limit. Fixes crashers
2177 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002178
Georg Brandl3ee81df2008-05-17 18:14:43 +00002179- Patch #1031213: Decode source line in SyntaxErrors back to its
2180 original source encoding.

2183 with %G.
2184
Georg Brandl3ee81df2008-05-17 18:14:43 +00002185- Prevent expandtabs() on string and unicode objects from causing a
2186 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002187

Georg Brandl3ee81df2008-05-17 18:14:43 +00002190- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00002191
Neal Norwitz0ac60192007-05-27 04:08:54 +00002192- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002193 __*__ attributes. (Some already existed, e.g., __doc__ and
2194 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002195
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002196- Add -3 option to the interpreter to warn about features that are
2197 deprecated and will be changed/removed in Python 3.0.
2198
Georg Brandl2134e752007-05-21 20:34:16 +00002199- Patch #1686487: you can now pass any mapping after '**' in function
2200 calls.
2201
Collin Winter62903052007-05-18 23:11:24 +00002202- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002203 "except E as target:". This is to provide forwards compatibility
2204 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002205
Brett Cannon229cee22007-05-05 01:34:02 +00002206- Deprecate BaseException.message as per PEP 352.
2207
Georg Brandl3ee81df2008-05-17 18:14:43 +00002208- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002209 inherited from a builtin base.
2210
Vinay Sajip8549ce32007-05-06 17:53:37 +00002211- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002212 setting a plain string, ie don't expand to single letter identifiers.
2213
Raymond Hettinger13936692007-04-11 18:40:58 +00002214- Request #1191699: Slices can now be pickled.
2215
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002216- Request #1193128: str.translate() now allows a None argument for
2217 translations that only remove characters without re-mapping the
2218 remaining characters.
2219
Georg Brandl5cb76c12007-03-21 09:00:39 +00002220- Patch #1682205: a TypeError while unpacking an iterable is no longer
2221 masked by a generic one with the message "unpack non-sequence".
2222
Neal Norwitzaa754b72007-03-21 06:39:48 +00002223- Remove unused file Python/fmod.c.
2224
Guido van Rossum143b5642007-03-23 04:58:42 +00002225- Bug #1683368: The object.__init__() and object.__new__() methods are
2226 now stricter in rejecting excess arguments. The only time when
2227 either allows excess arguments is when it is not overridden and the
2228 other one is. For backwards compatibility, when both are
2229 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002230 warning later). Also, type.__init__() insists on the same signature
2231 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002232
Georg Brandl3ee81df2008-05-17 18:14:43 +00002233- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2234 object to complex using its __complex__() method before falling back
2235 to the __float__() method. Therefore, the functions in the cmath
2236 module now can operate on objects that define a __complex__()
2237 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002238
Georg Brandl3ee81df2008-05-17 18:14:43 +00002239- Patch #1623563: allow __class__ assignment for classes with
2240 __slots__. The old and the new class are still required to have the
2241 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002242
Georg Brandl3ee81df2008-05-17 18:14:43 +00002243- Patch #1642547: Fix an error/crash when encountering syntax errors
2244 in complex if statements.
Collin Winter77c67bd2007-03-16 04:11:30 +00002245
Georg Brandl3ee81df2008-05-17 18:14:43 +00002246- Patch #1462488: Python no longer segfaults when
2247 ``object.__reduce_ex__()`` is called with an object that is faking
2248 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002249
Georg Brandl3ee81df2008-05-17 18:14:43 +00002250- Patch #1680015: Don't modify __slots__ tuple if it contains an
2251 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00002252
Georg Brandl5240d742007-03-13 20:46:32 +00002253- Patch #1444529: the builtin compile() now accepts keyword arguments.
2254
Georg Brandl7b9c5552007-03-12 14:30:05 +00002255- Bug #1678647: write a newline after printing an exception in any
2256 case, even when converting the value to a string failed.
2257
Georg Brandl871f1bc2007-03-12 13:17:36 +00002258- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002259 its argument, if it exists. If not, it will work like before. This
2260 allows customizing the output of dir() in the presence of a
2261 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002262
Collin Winter276887b2007-03-12 16:11:39 +00002263- Patch #922167: Python no longer segfaults when faced with infinitely
2264 self-recursive reload() calls (as reported by bug #742342).
2265
Georg Brandl3ee81df2008-05-17 18:14:43 +00002266- Patch #1675981: remove unreachable code from ``type.__new__()``
2267 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002269- Patch #1491866: change the complex() constructor to allow
2270 parthensized forms. This means complex(repr(x)) now works instead of
2271 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002272
Georg Brandlaa2321b2007-03-07 00:40:28 +00002273- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002274 makes the filenames the warning module prints much more sensible
2275 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002276
Georg Brandl49aafc92007-03-07 00:34:46 +00002277- Variant of patch #697613: don't exit the interpreter on a SystemExit
2278 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002279 variable is given, but break into the interactive interpreter just
2280 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00002281
Georg Brandl3ee81df2008-05-17 18:14:43 +00002282- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002285- Bug #1674503: close the file opened by execfile() in an error
2286 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002287
Georg Brandl0fca97a2007-03-05 22:28:08 +00002288- Patch #1674228: when assigning a slice (old-style), check for the
2289 sq_ass_slice instead of the sq_slice slot.
2290
Georg Brandl3ee81df2008-05-17 18:14:43 +00002291- When printing an unraisable error, don't print exceptions. before
2292 the name. This duplicates the behavior whening normally printing
2293 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002294
Georg Brandl3ee81df2008-05-17 18:14:43 +00002295- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00002795- Added a timeout parameter to the constructor of other protocols
2796 (telnetlib, ftplib, smtplib and poplib). This is second part of the
2797 work started with create_connection() and timeout in httplib, and
2798 closes patch #723312.
2799
Vinay Sajip8549ce32007-05-06 17:53:37 +00002800- Patch #1676823: Added create_connection() to socket.py, which may be

Facundo Batista70f996b2007-05-21 17:32:32 +00002802 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00002803

2824
Georg Brandlf66b6032007-03-14 08:27:52 +00002825- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00002826 AttributeError instead of an IOError when the server's response
2827 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00002828
Georg Brandl3ee81df2008-05-17 18:14:43 +00002829- Patch #957650: "%var%" environment variable references are now
2830 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00002833- Patch #1429539: pdb now correctly initializes the __main__ module
2834 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00002835 correctly now.
2836
Georg Brandlbad6f192007-03-13 21:32:56 +00002837- The nonobvious commands.getstatus() function is now deprecated.

2843
Georg Brandl3ee81df2008-05-17 18:14:43 +00002844- Patch #1530482: add pydoc.render_doc() which returns the

2854 parameter which can be set to False to prevent the default
2855 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00002856
Georg Brandl9e6b4702007-03-13 18:15:41 +00002857- Patch #1581073: add a flag to textwrap that prevents the dropping of
2858 whitespace while wrapping.
2859
Georg Brandl92a6bae2007-03-13 17:43:32 +00002860- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002861 are set for invalid interpolation sequences that would lead to
2862 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00002863

Georg Brandl3ee81df2008-05-17 18:14:43 +00002878 field names in its exception message if you try to write a record
2879 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00002897

2902 Python would crash instead of raising an error.
2903

2905 returned string up to the first NUL character.
2906

2916
Georg Brandl3ee81df2008-05-17 18:14:43 +00002917- unittest now verifies more of its assumptions. In particular,
2918 TestCase and TestSuite subclasses (not instances) are no longer
2919 accepted in TestSuite.addTest(). This should cause no
2920 incompatibility since it never made sense with ordinary subclasses
2921 -- the failure just occurred later, with a more cumbersome
2922 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00002923

2932
Georg Brandl3ee81df2008-05-17 18:14:43 +00002933- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003311 time so that opening a database previously created with the DB_DUP
3312 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3313 opens. Specifically: dictionary assignment to a DB object will
3314 replace all values for a given key when the database allows
3315 duplicate values. DB users should use DB.put(k, v) when they want
3316 to store duplicates; not DB[k] = v.

3323 characters with ASCII value less than 32. Also, it correctly quotes
3324 dots only if they occur on a single line, as opposed to the previous
3325 behavior of quoting dots if they are the second character of any
3326 line.
