Georg Brandld2094602008-12-05 08:51:30 +000093 method on file objects with closefd=False. The file descriptor is still

307 302 conformant loader) will now work correctly in most cases (they
308 are still subject to the constraints that exist for all code running

468What's New in Python 2.6.1
469==========================
470
471*Release date: 04-Dec-2008*
472
473Core and Builtins
474-----------------
475
476- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
477 interpreter to abort ("Fatal Python error: Could not reset the stack!")
478 instead of throwing a MemoryError.
479
480- Issue #4367: Python would segfault during compiling when the unicodedata
481 module couldn't be imported and \N escapes were present.
482
483- Issue #4348: Some bytearray methods returned that didn't cause any change to
484 the bytearray, returned the same bytearray instead of a copy.
485
486- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
487
488- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
489
490- Issue #4048: The parser module now correctly validates relative imports.
491
492- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
493 exec statement.
494
495- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
496 method does not return iterators for the 4th and 5th items.
497
498- Issue #4209: Enabling unicode_literals and the print_function in the same
499 __future__ import didn't work.
500
501- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
502 returned a path longer than MAX_PATH. (But It's doubtful this code path is
503 really executed because I cannot move to such directory on win2k)
504
505- Issue #4069: When set.remove(element) is used with a set element, the element
506 is temporarily replaced with an equivalent frozenset. But the eventual
507 KeyError would always report the empty frozenset([]) as the missing key. Now
508 it correctly refers to the initial element.
509
510- Fixed C99 style comments in several files. Python is now C89 compatible
511 again.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000660- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
661 PyString_FromFormat or PyErr_Format to display size_t values. The macro
662 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
663 ``printf`` function, whereas PyString_FromFormat has an independent

Vinay Sajip35e3b032008-09-01 14:33:59 +0000685- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000686 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
687 mechanism. In the process, fix a bug where isinstance() and issubclass(),
688 when given a tuple of classes as second argument, were looking up
689 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
690 type object.

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

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000826What's New in Python 2.6 beta 3?
827================================
828
Barry Warsaw07a4a382008-08-21 01:15:08 +0000829*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000830
831Core and Builtins
832-----------------
833
Guido van Rossumf8402962008-08-20 15:01:50 +0000834- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
835 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
836 extensions do not automatically benefit from the class attribute
837 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
838 to their tp_flags field if they care. This is a backwards
839 compatibility feature; in 3.0, all types will use the cache by
840 default.
841
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000842- Keyword arguments can now follow starred arguments. (``f(a, *args,
843 keyword=23)`` is now valid syntax.)
844
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000845- ctypes function pointers that are COM methods have a boolean True
846 value again.
847
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000848- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
849 by denying s# to parse objects that have a releasebuffer procedure,
850 and introducing s*.
851
Georg Brandl1e13ea92008-08-11 09:07:59 +0000852- Issue #3537: Fix an assertion failure when an empty but presized dict
853 object was stored in the freelist.
854
Mark Dickinsonb6467572008-08-04 21:30:09 +0000855- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
856 ValueError consistently across platforms.
857
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000858- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
859 (64bit Unix, for example), unichr() would truncate its argument and return
860 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
861
Neal Norwitze7d8be82008-07-31 17:17:14 +0000862- Apply security patches from Apple.
863
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000864- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
865 PyErr_ExceptionMatches returns 0 when an exception occurs there.
866
Antoine Pitrou92f82162008-07-25 22:22:08 +0000867- Issue #1819: function calls with several named parameters are now on
868 average 35% faster (as measured by pybench).
869
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000870- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
871 the python debugger steps into a class statement: the free variables (local
872 variables defined in an outer scope) would be deleted from the outer scope.
873
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000874- Issue #2620: Overflow checking when allocating or reallocating memory
875 was not always being done properly in some python types and extension
876 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
877 all been updated to perform better checks and places in the code that
878 would previously leak memory on the error path when such an allocation
879 failed have been fixed.

888
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000889- Issue #2234: distutils failed for some versions of the cygwin compiler. The
890 version reported by these tools does not necessarily follow the python
891 version numbering scheme, so the module is less strict when parsing it.
892
Nick Coghlanf70385a2008-08-18 12:42:46 +0000893- Issue #2235: Added Py3k warnings for types which will become unhashable
894 under the stricter __hash__ inheritance rules in 3.0. Several types
895 which did not meet the rules for hash invariants and were already
896 unhashable in 3.0 have now been explicitly flagged as unhashable in
897 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
898 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
899
Brett Cannon88f801d2008-08-18 00:46:22 +0000900- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

908
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000909- Issue #3575: Incremental decoder's decode function now takes bytearray
910 by using 's*' instead of 't#'.
911
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000912- Issue #2222: Fixed reference leak when occured os.rename()
913 fails unicode conversion on 2nd parameter. (windows only)
914
Facundo Batista94f243a2008-08-17 03:38:39 +0000915- Issue 2464. urllib2 now supports a malformation in the URL received
916 in a redirect.

Facundo Batistaeb90b782008-08-16 14:44:07 +0000921- Issue #2776: fixed small issue when handling an URL with double slash
922 after a 302 response in the case of not going through a proxy.
923
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000924- Issue #2676: in the email package, content-type parsing was hanging on
925 pathological input because of quadratic or exponential behaviour of a
926 regular expression.
927
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000928- Issue #3476: binary buffered reading through the new "io" library is now
929 thread-safe.
930
Brett Cannonbf3157b2008-08-14 05:00:03 +0000931- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
932 since mimetools itself is deprecated. Because modules are cached, all
933 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
934
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000935- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +0000937- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
938 menu entries were not deleted.
939
Brett Cannon83e81842008-08-09 23:30:55 +0000940- Copied the implementation of reduce() to _functools.reduce() to have a
941 version that did not raise a DeprecationWarning under -3.
942
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000943- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
944 a MemoryError rather than silently stop the iteration.
945
Guido van Rossum59ce9012008-08-09 14:55:34 +0000946- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
947 to _sre.compile() will now be rejected. This should not affect anybody
948 since the re.compile() function never generates invalid re-bytecode.
949
Skip Montanaroa032bf42008-08-08 22:52:51 +0000950- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
951 upon first access it can be automatically initialized from the csv file if
952 it wasn't initialized during instantiation.
953
Brett Cannon3aa2a492008-08-06 22:28:09 +0000954- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
955 the reload() built-in has been removed.

997 mode 0600 rather than 000 under Unix.
998
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000999- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1012 interaction with the tp_hash slot (added in 2.6b2) are now documented
1013
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001014- Issue #643841: The language reference now provides more detailed
1015 coverage of the lookup process for special methods. The disclaimers
1016 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001020What's New in Python 2.6 beta 2?
1021================================
1022
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001023*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001025Core and Builtins
1026-----------------
1027
Georg Brandl3e483f62008-07-16 22:57:41 +00001028- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1029 its methods now allow for items objects that can be converted to
1030 an integer using operator.index().
1031
Mark Dickinson64b7e502008-07-16 09:40:03 +00001032- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1033 produced a ValueError instead of giving the correct float.
1034
Eric Smitha5fa5a22008-07-16 00:11:49 +00001035- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1036 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1037
Mark Dickinson7103aa42008-07-15 19:08:33 +00001038- Issue #3008: the float type has a new instance method 'float.hex'
1039 and a new class method 'float.fromhex' to convert floating-point
1040 numbers to and from hexadecimal strings, respectively.
1041
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001042- Issue #2235: __hash__ is once again inherited by default. To allow
1043 collections.Hashable to remain meaningful in the presence of the
1044 default hash implementation (object.__hash__), it is now possible
1045 to explicit block inheritance of hash by setting __hash__=None at
1046 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1047 level.
1048
Nick Coghlanb028f502008-07-13 14:52:36 +00001049- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1050 the parent module cannot be found while performing an absolute import.
1051 This means that an incorrectly defined __package__ attribute will
1052 now only prevent relative imports in that module rather than causing
1053 all imports from that module to fail.
1054
Nick Coghlan14ff9942008-07-08 14:21:42 +00001055- Issue #2517: Allow unicode messages in Exceptions again by correctly
1056 bypassing the instance dictionary when looking up __unicode__ on
1057 new-style classes.

1060 set to a custom object whose write() method happens to install
1061 another file in sys.stdout.
1062
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001063- Issue #3088: Corrected a race condition in classes derived from
1064 threading.local: the first member set by a thread could be saved in
1065 another thread's dictionary.
1066
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001067- Issue #3004: Minor change to slice.indices(): the start and stop
1068 arguments are now treated identically, making the behaviour easier
1069 to describe and understand. For example, slice(None, -10,
1070 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1071 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1072 10, -1).
1073
Georg Brandl278fc502008-07-19 12:46:12 +00001074- Issue #3219: Calling a function with repeated keyword arguments,
1075 f(a=2, a=23), would not cause a syntax error. This was a regression
1076 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001077
Georg Brandl278fc502008-07-19 12:46:12 +00001078- Issue #2862: Make int and float freelist management consistent with
1079 other freelists. Changes their CompactFreeList apis into
1080 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001085- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1086 api functions without holding the GIL, which could lead to a fatal
1087 error when they failed.
1088
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001089- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001113
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001114- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1115 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001116 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001117 content-length. The problem had been corrected in the 2.4 branch, but never
1118 merged into trunk.
1119

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001133- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1134 handling is now the same as that of other special attributes like __name__).
1135
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001136- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00001588- Issue #1631171: Re-implement the 'warnings' module in C (the
1589 original Python code has been kept as backup). This will allow for
1590 using the 'warning's machinery in such places as the parser where
1591 use of pure Python code is not possible. Both the ``showarning()``
1592 and ``formatwarning()`` gain an optional 'line' argument which is
1593 not called by default for backwards-compatibility reasons. Setting
1594 ``warnings.showwarning()`` to an implementation that lacks support
1595 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001658- Issue #2550: The approach used by client/server code for obtaining
1659 ports to listen on in network-oriented tests has been refined in an
1660 effort to facilitate running multiple instances of the entire
1661 regression test suite in parallel without issue.
1662 test_support.bind_port() has been fixed such that it will always
1663 return a unique port -- which wasn't always the case with the
1664 previous implementation, especially if socket options had been set
1665 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1666 new implementation of bind_port() will actually raise an exception
1667 if it is passed an AF_INET/SOCK_STREAM socket with either the
1668 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1669 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1670 the socket it's been passed. This currently only applies to
1671 Windows. This option prevents any other sockets from binding to the
1672 host/port we've bound to, thus removing the possibility of the
1673 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1674 when a second SOCK_STREAM socket binds and accepts to a host/port
1675 that's already been bound by another socket. The optional preferred
1676 port parameter to bind_port() has been removed. Under no
1677 circumstances should tests be hard coding ports!
1678
1679 test_support.find_unused_port() has also been introduced, which will
1680 pass a temporary socket object to bind_port() in order to obtain an
1681 unused port. The temporary socket object is then closed and
1682 deleted, and the port is returned. This method should only be used
1683 for obtaining an unused port in order to pass to an external program
1684 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1685 a parameter to a server-oriented class that doesn't give you direct
1686 access to the underlying socket used.
1687
1688 Finally, test_support.HOST has been introduced, which should be used
1689 for the host argument of any relevant socket calls (i.e. bind and
1690 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001691
1692 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001693 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001694 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1695 test_asynchat and test_socket_ssl.
1696
Georg Brandl3ee81df2008-05-17 18:14:43 +00001697 It is now possible for multiple instances of the regression test
1698 suite to run in parallel without issue.

1965-----------------
1966
Fred Drakea8ee94b2008-03-01 02:45:07 +00001967- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001968 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00001973
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001974- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001975 issue 215555 for a discussion.
1976
Eric Smitha73fbe72008-02-23 03:09:44 +00001977- Added the future_builtins module, which contains hex() and oct().
1978 These are the PEP 3127 version of these functions, designed to be
1979 compatible with the hex() and oct() builtins from Python 3.0. They
1980 differ slightly in their output formats from the existing, unchanged
1981 Python 2.6 builtins. The expected usage of the future_builtins
1982 module is:
1983 from future_builtins import hex, oct
1984
Eric Smith7ef40bf2008-02-20 23:34:22 +00001985- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1986 exponents for exponents with absolute value < 100. Follows C99
1987 standard. This is a change on Windows, which would use 3 digits.
1988 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1989 so that any alterations it does to the resulting string will be
1990 available in stringlib/formatter.h (for float.__format__).
1991
Eric Smith5a3c1352008-02-19 13:21:56 +00001992- Implemented PEP 3101, Advanced String Formatting. This adds a new
1993 builtin format(); a format() method for str and unicode; a
1994 __format__() method to object, str, unicode, int, long, float, and
1995 datetime; the class string.Formatter; and the C API
1996 PyObject_Format().
1997
Georg Brandl3ee81df2008-05-17 18:14:43 +00001998- Fixed several potential crashes, all caused by specially crafted
1999 __del__ methods exploiting objects in temporarily inconsistent
2000 state.

2024 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002025 to compact the internal free lists of pre-allocted ints and floats.
2026
Georg Brandl3ee81df2008-05-17 18:14:43 +00002027- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2028 calls. Python expected the return type int but the fork familie
2029 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002043- Patch #1473257: generator objects gain a gi_code attribute. This is
2044 the same object as the func_code attribute of the function that
2045 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002046
Georg Brandl3ee81df2008-05-17 18:14:43 +00002047- Issue #1920: "while 0" statements were completely removed by the
2048 compiler, even in the presence of an "else" clause, which is
2049 supposed to be run when the condition is false. Now the compiler
2050 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002051

Georg Brandl6caad7d2008-01-26 14:19:22 +00002069- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002070 added.
2071
Christian Heimesc94e2b52008-01-14 04:13:37 +00002072- sys.float_info / PyFloat_GetInfo: The floating point information
2073 object was converted from a dict to a specialized structseq object.
2074
Georg Brandl3ee81df2008-05-17 18:14:43 +00002075- Patch #1816: Added sys.flags structseq. It exposes the status of
2076 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002077
Georg Brandl3ee81df2008-05-17 18:14:43 +00002078- Objects/structseq.c: Implemented new structseq representation. The
2079 patch makes structseqs (e.g. the return value of os.stat) more
2080 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002081
Georg Brandl3ee81df2008-05-17 18:14:43 +00002082- Patch #1700288: added a type attribute cache that caches method
2083 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002084
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002085- Bug #1776: __import__() no longer accepts filenames on any platform.
2086 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002087
Georg Brandlaed6c662008-01-07 17:25:53 +00002088- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2089
Georg Brandl3ee81df2008-05-17 18:14:43 +00002090- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2091 envvar and sys.dont_write_bytecode attribute. All these can be set
2092 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002093
Georg Brandl3ee81df2008-05-17 18:14:43 +00002094- Improve some exception messages when Windows fails to load an
2095 extension module. Now we get for example '%1 is not a valid Win32
2096 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002097
Georg Brandl3ee81df2008-05-17 18:14:43 +00002098- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002100- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2101 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002102
Christian Heimes0a8143f2007-12-18 23:22:54 +00002103- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002104 and INF. float("nan"), float("inf") and float("-inf") now work on
2105 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002106
Georg Brandl3ee81df2008-05-17 18:14:43 +00002107- Compiler now generates simpler and faster code for dictionary
2108 literals. The oparg for BUILD_MAP now indicates an estimated
2109 dictionary size. There is a new opcode, STORE_MAP, for adding
2110 entries to the dictionary.

2128 running, and if the deallocation of its frames somehow calls the
2129 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002130

2135
Georg Brandl3ee81df2008-05-17 18:14:43 +00002136- Issue #1460: The utf-7 incremental decoder did not accept truncated
2137 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002138
Georg Brandl3ee81df2008-05-17 18:14:43 +00002139- Patch #1739468: Directories and zipfiles containing a __main__.py
2140 file can now be directly executed by passing their name to the
2141 interpreter. The directory/zipfile is automatically inserted as the
2142 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002143
Georg Brandl3ee81df2008-05-17 18:14:43 +00002144- Issue #1265: Fix a problem with sys.settrace, if the tracing
2145 function uses a generator expression when at the same time the
2146 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002147
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002148- sets and frozensets now have an isdisjoint() method.
2149

2151
Neal Norwitz44f326e2007-10-05 05:29:17 +00002152- Fix warnings found by the new version of the Coverity checker.
2153
Georg Brandl3ee81df2008-05-17 18:14:43 +00002154- The enumerate() builtin function is no longer bounded to sequences
2155 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2156 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002157
Georg Brandl3ee81df2008-05-17 18:14:43 +00002158- Issue #1686386: Tuple's tp_repr did not take into account the
2159 possibility of having a self-referential tuple, which is possible
2160 from C code. Nor did object's tp_str consider that a type's tp_str
2161 could do something that could lead to an inifinite recursion.
2162 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2163 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002164
Georg Brandl3ee81df2008-05-17 18:14:43 +00002165- Issue #1164: It was possible to trigger deadlock when using the
2166 'print' statement to write to a file since the GIL was not released
2167 as needed. Now PyObject_Print() does the right thing along with
2168 various tp_print implementations of the built-in types and those in
2169 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002170
Georg Brandl3ee81df2008-05-17 18:14:43 +00002171- Issue #1147: Exceptions were directly allowing string exceptions in
2172 their throw() method even though string exceptions no longer
2173 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002174
Georg Brandl3ee81df2008-05-17 18:14:43 +00002175- Issue #1096: Prevent a segfault from getting the repr of a very
2176 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002177
Brett Cannon1e534b52007-09-07 04:18:30 +00002178- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002179 PyObject_Call() never calling back out to Python code to trigger
2180 recursion depth updates/checks. Required the creation of a static
2181 RuntimeError instance in case normalizing an exception put the
2182 recursion check value past its limit. Fixes crashers
2183 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002184
Georg Brandl3ee81df2008-05-17 18:14:43 +00002185- Patch #1031213: Decode source line in SyntaxErrors back to its

2189 with %G.
2190
Georg Brandl3ee81df2008-05-17 18:14:43 +00002191- Prevent expandtabs() on string and unicode objects from causing a
2192 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002198- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002199 __*__ attributes. (Some already existed, e.g., __doc__ and
2200 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002201
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002202- Add -3 option to the interpreter to warn about features that are
2203 deprecated and will be changed/removed in Python 3.0.
2204
Georg Brandl2134e752007-05-21 20:34:16 +00002205- Patch #1686487: you can now pass any mapping after '**' in function
2206 calls.
2207
Collin Winter62903052007-05-18 23:11:24 +00002208- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002209 "except E as target:". This is to provide forwards compatibility
2210 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002211
Brett Cannon229cee22007-05-05 01:34:02 +00002212- Deprecate BaseException.message as per PEP 352.
2213
Georg Brandl3ee81df2008-05-17 18:14:43 +00002214- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002215 inherited from a builtin base.
2216
Vinay Sajip8549ce32007-05-06 17:53:37 +00002217- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002218 setting a plain string, ie don't expand to single letter identifiers.
2219
Raymond Hettinger13936692007-04-11 18:40:58 +00002220- Request #1191699: Slices can now be pickled.
2221
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002222- Request #1193128: str.translate() now allows a None argument for
2223 translations that only remove characters without re-mapping the
2224 remaining characters.
2225
Georg Brandl5cb76c12007-03-21 09:00:39 +00002226- Patch #1682205: a TypeError while unpacking an iterable is no longer
2227 masked by a generic one with the message "unpack non-sequence".
2228
Neal Norwitzaa754b72007-03-21 06:39:48 +00002229- Remove unused file Python/fmod.c.
2230
Guido van Rossum143b5642007-03-23 04:58:42 +00002231- Bug #1683368: The object.__init__() and object.__new__() methods are
2232 now stricter in rejecting excess arguments. The only time when
2233 either allows excess arguments is when it is not overridden and the
2234 other one is. For backwards compatibility, when both are
2235 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002236 warning later). Also, type.__init__() insists on the same signature
2237 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002238
Georg Brandl3ee81df2008-05-17 18:14:43 +00002239- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2240 object to complex using its __complex__() method before falling back
2241 to the __float__() method. Therefore, the functions in the cmath
2242 module now can operate on objects that define a __complex__()
2243 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002244
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245- Patch #1623563: allow __class__ assignment for classes with
2246 __slots__. The old and the new class are still required to have the
2247 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002248
Georg Brandl3ee81df2008-05-17 18:14:43 +00002249- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002252- Patch #1462488: Python no longer segfaults when
2253 ``object.__reduce_ex__()`` is called with an object that is faking
2254 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002255
Georg Brandl3ee81df2008-05-17 18:14:43 +00002256- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002259- Patch #1444529: the builtin compile() now accepts keyword arguments.
2260
Georg Brandl7b9c5552007-03-12 14:30:05 +00002261- Bug #1678647: write a newline after printing an exception in any
2262 case, even when converting the value to a string failed.
2263
Georg Brandl871f1bc2007-03-12 13:17:36 +00002264- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002265 its argument, if it exists. If not, it will work like before. This
2266 allows customizing the output of dir() in the presence of a
2267 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002268
Collin Winter276887b2007-03-12 16:11:39 +00002269- Patch #922167: Python no longer segfaults when faced with infinitely
2270 self-recursive reload() calls (as reported by bug #742342).
2271
Georg Brandl3ee81df2008-05-17 18:14:43 +00002272- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Patch #1491866: change the complex() constructor to allow
2276 parthensized forms. This means complex(repr(x)) now works instead of
2277 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002278
Georg Brandlaa2321b2007-03-07 00:40:28 +00002279- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002280 makes the filenames the warning module prints much more sensible
2281 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002282
Georg Brandl49aafc92007-03-07 00:34:46 +00002283- Variant of patch #697613: don't exit the interpreter on a SystemExit
2284 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002285 variable is given, but break into the interactive interpreter just
2286 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002294- Patch #1674228: when assigning a slice (old-style), check for the
2295 sq_ass_slice instead of the sq_slice slot.
2296
Georg Brandl3ee81df2008-05-17 18:14:43 +00002297- When printing an unraisable error, don't print exceptions. before
2298 the name. This duplicates the behavior whening normally printing
2299 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00002801- Added a timeout parameter to the constructor of other protocols
2802 (telnetlib, ftplib, smtplib and poplib). This is second part of the
2803 work started with create_connection() and timeout in httplib, and
2804 closes patch #723312.
2805
Vinay Sajip8549ce32007-05-06 17:53:37 +00002806- Patch #1676823: Added create_connection() to socket.py, which may be

Facundo Batista70f996b2007-05-21 17:32:32 +00002808 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00002809

2830
Georg Brandlf66b6032007-03-14 08:27:52 +00002831- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00002832 AttributeError instead of an IOError when the server's response
2833 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00002834
Georg Brandl3ee81df2008-05-17 18:14:43 +00002835- Patch #957650: "%var%" environment variable references are now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002839- Patch #1429539: pdb now correctly initializes the __main__ module
2840 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00002841 correctly now.
2842
Georg Brandlbad6f192007-03-13 21:32:56 +00002843- The nonobvious commands.getstatus() function is now deprecated.

2849
Georg Brandl3ee81df2008-05-17 18:14:43 +00002850- Patch #1530482: add pydoc.render_doc() which returns the

2860 parameter which can be set to False to prevent the default
2861 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00002863- Patch #1581073: add a flag to textwrap that prevents the dropping of
2864 whitespace while wrapping.
2865
Georg Brandl92a6bae2007-03-13 17:43:32 +00002866- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867 are set for invalid interpolation sequences that would lead to
2868 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00002869

Collin Winter22c42ba2007-03-10 02:51:26 +00002903

2908 Python would crash instead of raising an error.
2909
Thomas Hellerc2f77252007-03-09 19:21:28 +00002910- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
2911 returned string up to the first NUL character.
2912

2922
Georg Brandl3ee81df2008-05-17 18:14:43 +00002923- unittest now verifies more of its assumptions. In particular,
2924 TestCase and TestSuite subclasses (not instances) are no longer
2925 accepted in TestSuite.addTest(). This should cause no
2926 incompatibility since it never made sense with ordinary subclasses
2927 -- the failure just occurred later, with a more cumbersome
2928 exception.

2938
Georg Brandl3ee81df2008-05-17 18:14:43 +00002939- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003317 time so that opening a database previously created with the DB_DUP
3318 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3319 opens. Specifically: dictionary assignment to a DB object will
3320 replace all values for a given key when the database allows
3321 duplicate values. DB users should use DB.put(k, v) when they want
3322 to store duplicates; not DB[k] = v.

3329 characters with ASCII value less than 32. Also, it correctly quotes
3330 dots only if they occur on a single line, as opposed to the previous
3331 behavior of quoting dots if they are the second character of any
3332 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003333

3678 of w# format code incorrectly truncated the length to an int, even
3679 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3680 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003710- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3711 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
