Thanks, I'll have a look at that. Hopefully it will help the effort of
porting Resolver One to IP2.

In 2.0 this is actually easier. You could modify the DLR in MetaAction.cs to
wrap every single dynamic operation - whether that be addition, calling
something, getting a member, etc... There's a method called GetMetaObjectRule
and it has:
Expression body = rewriter.VisitNode(AddReturn(binding.Expression,
retType));
You could modify this to be something like:
Expression tmp = Expression.Variable(body.Type);
body = Expression.Scope(
Expression.Call(
Expression.Comma(
Expression.Call(typeof(MyType).GetMethod("Enter")), // MyType is some
public type somewhere...
Expression.Assign(tmp, body),
Expression.Call(typeof(MyType).GetMethod("Exit")),
tmp
)
),
tmp
)
);
And you'd get information on every call - warning, this code was compiled with
Outlook.

Subject: [IronPython] Patched, profiling IronPython executable?
Hi,
following all the discussion about profiling etc, I was poking around in
IP1.1.2 source code, trying to find out if there is a 'bottleneck' of
sorts, that all function calls are threaded through. My thinking was
that it would be then possible to surround this with profiling
information, logging time taken etc. and compile a profiling ipy.exe.
From my venture, I think that ICallable is what I should be looking
for. I see that it has many implementors, but I guess FastCallable (in
all its generated glory) should capture a lot of the cases, right?
Am I even on the right track here?
