Hi all
While running the numpy tests, I've come across a situation which, to
the best of my knowledge, is simply impossible. I'm hoping that one of
the local .NET gurus will be able to tell me what I'm missing, or point
me somewhere I can get more insight.
The 4 methods involved are as
Incidentally, logging a Stopwatch timestamp in WriteFlush reveals that,
yes, the calls really are happening in the order they appear to be. So,
option (3) appears to be a red herring, and options (1) and (2) remain
unchanged.

Can't you just do..
'variable_name' in locals()
or
'variable_name' in dir()

Hello Guys,
Discovered a bug in indexing Python objects in IronPython 2.
The following code:
class X(object):
def __setitem__(self, key, value):
print repr(key)
def f(a, b):
X()[a, b] = object()
f(1, 2)
f('one', 'two')
Produces the following exception:
Traceback (most
...or, for that matter, any __del__ methods from within Python -- which
ultimately are handled by finalization.

Hi Curt
I am indeed; that's how I know thread 2 is the GC thread. Is locking
during GC forbidden?

Locking during finalization is often considered to be a bad idea. In
particular, locking without a timeout introduces the possibility that you
will hang the finalization thread, preventing further objects from being
finalized. But clearly, that's not what's happening here.
Other questions that
The log starts in the middle (after many lock/unlocks, some from each
thread); I'm running on x86; and I have no additional AppDomains.
I don't think it would be safe for me to entirely avoid locking during
finalization, but I could probably cut it down to a quick lock, on a
separate object,
Thanks for the report. I've opened CodePlex bug #19350 to track this
(http://www.codeplex.com/IronPython/WorkItem/View.aspx?WorkItemId=19350).
I believe the fix is actually pretty simple and we'll discuss whether we'll
take it for 2.0 final at our Friday team meeting. If you want to try out
That worked great, thanks.

Is there the equivalent of extension method in python? I want to put a
variable into the script scope and create extension methods for it.
Does this make sense and is it possible?

If it's an object defined in Python you can usually attach methods directly to
the object or it's Python type. But otherwise we have no support for
automatically adding .NET extension methods to existing types currently. It is
a frequent request and we will probably get to it at some point.
If it's an object defined in Python you can usually attach methods
directly to the object or it's Python type.
So how would this work?
Let's say I had injested a variable into the scope from c#:
scope.SetVarialble(widget, hello world)
Can I do something in python so that I can then
In this case widget is the string hello world so it won't work. If it was
instead something like:
class x(object): pass
a = x()
...
Then in C# you could do:
widget = scope.GetVariable(a)
then you could do engine.Operations.SetMember(widget, foo, () = hello
world);
and then back in Python:
Hi IronPython team,
Is there any reason why _WindowsError sets errno to 22 in all cases?
There's some code in Django that checks if e.errno = errno.EEXIST. The
exception that gets thrown by IronPython has winerror = 17 (and the
message string says [Errno 17]...!), but e.errno is 22 (EINVAL).
It's because when I initially looked at WindowsError it sure seemed like 22 was
the error code that was always used :). If you do:
for i in xrange(100):
print WindowsError(i, i).errno
on CPython You'll see a large amount of the errno's are set to 22 (including 0
and 1) - apparently I
I would suggest getting a snap shot of the call stacks when this is happening
if that's possible. I can't pin anything down but I wonder if you could have
an STA object or something that otherwise requires message pumping. That
message pumping could happen while you're doing a Monitor.Enter
