Hello IronPython Community, We have just released IronPython 1.0 Beta 4. This is yet
another release focusing primarily on fixing bugs. Since the beta 3 release
we’ve cut our active number of bugs in half. Unfortunately we
didn’t get to review the PythonEngine APIs in this release but will be
getting this done for the next beta. Although major changes are few in this release some of the
bigger changes include: Fix beta 3 assembly loading bug Auto-indentation support for the super console Support pep-263 file encodings AST visitor changes (*) A more complete list of changes follows at the end. You can download the release from: http://www.microsoft.com/downloads/details.aspx?FamilyID=ab942d78-b3df-428d-a2e7-f80949607c1a&displaylang=en We'd like to thank everyone in the community for your bug
reports and suggestions that helped make this a better release: Alex Martelli,
Anthony Tarlano, Chee Meng, Erin Renshaw, Giles Thomas, Greg Lee, grizupo, J.
Merrill, Jeff Griffiths, Jon Kale, minwei, Neville Bagnall, Nicholas Jacobson,
Paparipote, Richard Hsu, Richard Bothne, and Sanghyeon Seo. Thanks and keep in touch, The IronPython Team (*) The AST visitor changes in IronPython 1.0 Beta 4 are not
compatible with the IronPython Visual Studio integration released in the March
CTP of the Visual Studio SDK. Some code changes in the VS integration sample are
required to use it with the latest IronPython 1.0 Beta 4. More complete list of changes and bug fixes: ============================================ Bugfix: Infinite recursion in import code Traceback support Support for methods only implemented via explicit interface
implementation Bugfix: SubClass check throws ArgumentNull Exception Bugfix: Slice is (incorrectly) hashable WAS: dict[:] showing
KeyError instead of TypeError Bugfix: tuple unpacking issues Bugfix: Calling __str__ on a Python exception class object
causes an IndexError Bugfix: Trying to set methods on "built-in"
classes fails silently Bugfix: Inheriting from an interface causes peverify
warnings Bugfix: raise "foo" raises an exception, but is
eaten by top-level rather than reported Bugfix: eval - locals can be any mapping object (formerly
required to be a dictionary) Bugfix: Calling exc_info when there is no exception in the
current stack causes a NullRef, rather than returning (None, None, None) Bugfix: Index out of bounds exception when importing minidom Bugfix: sequence.index(None) and sequence.count(None) should
throw Type error instead of ArgNullExcep Bugfix: "abc".find(None) throws SystemError:
"Object reference not set to an instance of an object." Bugfix: "except <name>, <data>"
statement does not capture exception data; <data> is just a copy of the
exception Bugfix: sgmllib running on tutorial.htm throws Bugfix: Regular expressions: RE_Pattern instance method
match(text, pos, endpos) not implemented Bugfix: multiline string does not return to primary
interpreter prompt Bugfix: re.split with maxcount != 0 differs from
specification Bugfix: Old class comparisons give wrong results, same as
User Type Bugfix: IronPython won't call custom comparison operators on
.NET types Bugfix: IronPython creates instance of class with __module__
set to contents of __name__ rather than the module name Bugfix: IP uses wrong slot to generate classe's module name Support for constructing Python file from .NET Stream Bugfix: Subclassing str & creating subclass fails Bugfix: Fix call to System.Double.ToString(1.0, 'f')
(ReflectedOps types not storing both Python & non-Python names) Bugfix: -u command line option Bugfix: For an old-style class C, str(C) != C.__module__ +
'.' + C.__main__ Bugfix: SyntaxError raised when a function defined to take
kwargs is called with the name of the kwargs parameter as one of the
keyword-specified argument Bugfix: Better formatting for System.Single Bugfix: Improve string formatting of floats for better
compat with CPython Bugfix: sys.argv doesn't include executed python script Bugfix: IronPython builtin f.read() functionality differs
from CPython builtin f.read() functionality Bugfix: CPython/IronPython discrepancy when comparing
strings Bugfix: +=, ... also bind locals, fix binder Bugfix: CPython/IronPython discrepancy in behavior with
respect to power operation Bugfix: ComplexOps.FloorDivide just does ordinary division Bugfix: Make PythonFile more robust WAS:
sys.__stdin__.write("blah\n") causing NullReferenceException in
IronPython Bugfix: Opening a file for writing and then attempting to
read before closing the file causes a NullReferenceException Bugfix: Implement -c command line argument Bugfix: Add ability to compiler to generate 32 bit or 64 bit
assemblies Bugfix: Fix compiler resource support Bugfix: from __future__ imports must occur at the beginning
of the file, but can after the comments Bugfix: eval failed to find local name Bugfix: multiline string can't have blank lines Bugfix: better error message for functions with default
arguments Bugfix: buffer() throws exception with message referring to
method "ctor" instead of the expected "buffer" Bugfix: Encoding/Decoding tests in tests_str.py disabled Bugfix: In a Python subclass of a .NET class, inherited (but
not overriden) methods are not shown as attributes of either class or instance Bugfix: Finish time module (day of year / week of year
custom formatting) Bugfix: @accepts, @returns decorators not yet defined in clr
module Bugfix: Can't inherit from interfaces with properties Bugfix: unicode(xxx ','raw-unicode-escape') issue Bugfix: The error message associated with incorrect usage of
constructors of builtin types are confusing Bugfix: Method dispatch: skip generic method when bindmethod Bugfix: Investigate why CPython throws a syntax error for a
compile statement that IronPython parses correctly Bugfix: NoneType arguments to coerce() causing unexpected
SystemErrors Bugfix: Stack overflow adding reference to System.Xml Bugfix: re.compile does not accept "\\_" as a
valid escape sequence Bugfix: re module - difference result of not matched group Bugfix: Interactive console not parsing certain 'if'
statements correctly Implement -E command line parameter Implement -OO command line parameter Implement -S command line parameter Implement -t command line parameter Implement -V command line parameter Implement '-' command line parameter Bugfix: Pay customdict, frame, env refactoring debt Bugfix: Default parameters are not available for functions
generated as DynamicMethod Bugfix: Method dispatch: the story of None as parameter Do
