IronPython 2.0.2 Released

By Michael Foord -
Work on IronPython 2.6 progresses (there is even a new page that appeared overnight comparing the performance of the as-yet-unreleased 2.6 Beta 2 to CPython 2.6.1).

In the meantime there has been a bugfix release on the stable IronPython 2.0 branch - IronPython 2.0.2 has just been released.
This release is a minor update to IronPython 2.0.1, which in turn is a CPython 2.5-compatible release running on the .NET platform. Our priority was to make IronPython 2.0.2 a bugfix release that remains backwards-compatible with IronPython 2.0.1. In particular, we focused on issues the IronPython community brought to our attention through codeplex. As such, there have been important improvements on the compatibility and stability of IronPython as summarized below.
Detailed change summary:
  • 21577 – binascii.crc32 doesn't accept one argument.
  • 20616 – wrong TypeError message when invoking "str.join": implicit parameter 'self' not counted
  • 19665 – 2.0.2: operator.isSequenceType(NewStyleClass) broken
  • 20087 – 2.0.2: Null Value Exception in COM interop
  • 21445 – DLR: There is a dead loop in CallSite.UpdateAndExecute(), which leads to IronPython 2.0.1 hang.
  • 22001 – 2.0.2: Ngen IronPython.msi option doesn't work on 64-bit platforms?
  • 22094 – 2.0.2: StringException leaked to Python via sys.exc_info()
  • 22239 – 2.0.2: modules aren't isolated
  • 20634 – hex_codec needs to be imported before hex decode can happen
  • 20302 – codecs.lookup errors with uppercase encoding names
  • 20051 – Re-raising exception causes loss of traceback
  • 4565 – Support all encodings CPython does for _codecs.encode and _codecs.decode
  • 20603 – os.walk(‘’) doesn’t work
  • 21929 – os.listdir does not accept empty path
  • 17235 – dir(System.ArgIterator) broken
Silverlight users: A new version of Silverlight, specifically Silverlight 3, is required to build the “Silverlight Release” or “Silverlight Debug” configurations of IronPython.sln. Please update Silverlight accordingly if you intend to do so.

Extending Abobe Flash Player and AIR with Python and Ruby

By Michael Foord -
An intriguing blog entry about an Adobe experimental project. It is a C/C++ cross- compiler for the flash player and AIR. This means that you can (will be able to?) cross-compile the Python / Ruby/ lots of other language runtimes and then run them in Flash. The blog entry contrasts this approach to the DLR which requires the re-implementation of dynamic languages - hence IronPython and IronRuby. The project is already beyond proof-of concept, they even have Quake III cross-compiled and running in Flash. Extending Adobe Flash Player and AIR with C/C++ Cross-Compiler Quake 3 has already been ported to managed code , but this is even more impressive. Whether the Python interpreter can be cross-compiled to run on top of another runtime (with completely different basic types), without changing the language semantics at all, has yet to be proved - but it is a very interesting project. (It also means that Python/Ruby will possibly be enabled only by additional optional downloads - but don'

Should Python Projects Support IronPython and Jython?

By Michael Foord -
The maintainers of the Spring Framework for Python ( Spring Python ) wonder how much of a priority it is to have compatibility with platforms other than CPython. In other words, should they support IronPython and Jython - and if so what should they do about their C extension dependencies? This question sparks a good discussion and is relevant to many other Python projects and applications: Need for supporting IronPython, Jython? " One of the topics on my mind recently, as we consider refactoring the core container, is how we ensure that when we introduce internal dependencies, such as possibly the Amara libraries for XML processing, what secondary constraints we might be introducing. " " For example, Amara represents a very pythonic and therefore simple to read and use approach to developing XML processing, such as our very own XML application configuration parsers. So from that perspective, things are very attractive. But then you ask the question, "can I run this

Further Adventures of the Debugger

By Michael Foord -
Harry Pierson (Microsoft IronPython PM) has been experimenting with writing an IronPython debugger ( ipydbg ) on top of the .NET MDbg APIs. When we last left him , he had implemented Just My Code (JMC) support allowing you to step into IronPython code. Since then he has made a lot of progress including a colourful REPL (interactive console) and solving some difficult problems around getting to real values behind boxed IronPython variables (needed for showing local variables). He has blogged extensively on what he has been up to (more recent posts last): Showing Source Code Colorful Console IronPython ConsoleColorMgr (the colorful console code pulled out into a separate IronPython module) A Little Hack...err...Cleanup Getting Local Variables Displaying Values Command Routing Getting Arguments REPL Console A lot of functionality is now present. In the command routing entry Harry outlines the seven commands supported by the debugger so far: Continue, Quit, Show Stack Trace, Show Locals,
