Debugging with 1.3 and CDT

[Daniel Renfer]

I'm trying to set up debugging for my application using the Clojure Debugging Toolkit. I'm fairly certain I have everything set up properly, but I can't seem to get it to "reval" appropriately.

I am using the Clojure maven plugin to launch a swank server. (with the debugging args from George's site) I am using Clojure 1.3, which I think may be part of my problem. I am able to set breakpoints, step in, step out, continue, etc. As soon as I try to do any reval-ing, I get an exception. (this includes trying to print locals)

The stacktrace of the exception is:

com.sun.jdi.InvocationException: Exception occurred in target VM (NO_SOURCE_FILE:0)

I'm AOT compiling my classes, if that makes a difference. Does anyone know what might be going on? If I were upgrade CDT and the debug-repl to 1.3, would that help? Also, I'm sure I don't have all my source paths set up properly in emacs, but I don't think that's the problem in this case. (Ubuntu 10.10, OpenJDK Runtime Environment (IcedTea6 1.9.4))

Hey Daniel:

I'm embarrassed to say I've never tried it before on 1.3. You've
found a real bug. I'll try to get a proper patch out later today, but
if you're in a hurry, you might try changing this line in cdt.clj:

(def ge (memoize #(first (find-methods (va) #"get"))))

to this:

(def ge (memoize #(first (find-methods (va) #"get$"))))

Let me know how it goes.

Thanks for "going were no man has gone before!"

That did the trick.

The keys on my keyboard that spell out "println" thank you.
