Re: org.junit.Assert/assertArrayEquals massive confusion!
It doesn't seem to be in the published javadoc, but this is an array comparison with an epsilon tolerance, which was likely added after the published javadoc was generated. 0.01 here is the maximum permitted absolute difference between each compared number. https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/Assert.java#L474 peace, Chris On Tue, May 28, 2013 at 12:42 PM, Jim - FooBar(); wrote: > Hi everyone, > > sometimes I feel really stupid! > > I am currently looking at a well-known java library's tests and found this: > > Assert.assertArrayEquals(arrayOutput[0], arrayOutput[1], 0.01); > //arrayOutput is a 2d double-array btw > > since I've basically wrapped this lib, I'd like to port the java tests as > well.

Re: ANN Ritz 0.5.0
I am also having trouble getting the nrepl-ritz debugger to start. I am able to start a repl with M-x nrepl-ritz-jack-in. Then when I do M-x nrepl-ritz-break-on-exception and type '(throw (Exception. "OHAI"))' into the repl, what happens is that I see "nrepl-dbg-setup 1" in the minibuffer and the repl becomes unresponsive. The process is still alive, but nothing ever comes back to the buffer. Am I missing some important part of setup here? I have Clojure 1.4.0, clojure-mode 1.11.5, nrepl.el 0.1.4, ritz 0.5.0, Emacs 24.2.1 on Mac OS 10.6; all the Emacs packages were installed from marmalade. thanks, Chris Jeris On Mon, Sep 24, 2012 at 10:49 PM, Hugo Duncan wrote: > > Tim, > > > Timothy Washington writes: > > > I was following the instructions on the ritz-nrepl > > page<https://github.com/pallet/ritz/tree/develop/nrepl>.

AOT-compilation, record types and DynamicClassLoader
I have a problem where I am trying to do an isa? or instance? check on an object of a record type which is defined in an AOT-compiled namespace. The isa? check fails because -- under circumstances which I do not yet well understand -- the object I actually have is an instance of its class in a clojure.lang.DynamicClassLoader, whereas a reference to the class by its literal name yields the class in the base sun.misc.Launcher$AppClassLoader. My Clojure code is compiled into a jar which is included into a Jetty server whose app code is largely written in Java. Here is an example which illustrates the problem: ;; src/foo/core.clj (ns foo.core) (defrecord T [a b]) ;; project.clj (defproject foo "1.0.0-SNAPSHOT" :dependencies [[org.clojure/clojure "1.4.0"]] :aot [foo.core]) Now if I add the artifact foo/foo as a Maven dependency of the Jetty server, and attach a liverepl to the running server (without taking any action to call the Clojure code from Java), I see the following: Clojure 1.4.0 user=> (require '[foo.core]) nil user=> (.getClassLoader foo.core.T) # user=> (.getClassLoader (type (foo.core.T. 1 2))) # user=> (.getClassLoader (type (foo.core/->T 1 2))) # My actual case is more complicated, but the principle is the same: instances of foo.core.T which were built by the defrecord constructor function ->T do not inhabit the AppClassLoader version of the class, but rather a DynamicClassLoader version. The result is that instance? or instanceof checks -- whether in my own Clojure code or in that of Java clients of my library who are trying to downcast -- do not behave as expected. This example cannot be reduced too far: if one just builds an uberjar and invokes a repl on the Clojure library alone, using 'java -cp target/foo-1.0.0-SNAPSHOT-standalone.jar clojure.main', the result is different: Clojure 1.4.0 user=> (require '[foo.core]) nil user=> (.getClassLoader foo.core.T) # user=> (.getClassLoader (type (foo.core.T. 1 2))) # user=> (.getClassLoader (type (foo.core/->T 1 2))) # Unfortunately I don't understand enough about the Clojure class loading mechanism to understand what might be causing the DynamicClassLoader to be invoked in one case and not the other. This problem seems to have been described by Ryan Senior about 20 months ago on clojure-dev, but I do not find any follow-up posts: https://groups.google.com/forum/?fromgroups=#!topic/clojure-dev/VBJFMEFBeFY Can anyone shed light on the situation? thanks, Chris Jeris -- Chris Jeris cje...@brightcove.com (617) 686-3271 freenode/twitter/github: ystael -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Help: instance? always false for record type (in tomcat but not in jetty)
In the Tomcat uberwar setting, is ns1 AOT-compiled? Are (.getClassLoader A) and (.getClassLoader (.getClass an-A-record)) different class loaders? That's what the problem was when this one bit me. I never did track down exactly why it happens or how to fix it. peace, Chris Jeris On Thu, Dec 13, 2012 at 6:13 PM, CGAT wrote: > I have a frustrating situation and would appreciate any help. > The call > >(instance?
