Clojure contrib profiler error

[Adrian Mowat]

Hi All

I'm trying to run the clojure contrib profiler and I'm getting an error.  Has anyone faced the same problem?

user=> (use 'clojure.contrib.profile)

nil

user=> (defn my-function [x y]

                (let [sum (prof :addition (+ x y))

                      product (prof :multiplication (* x y))]

                  [sum product]))

#'user/my-function

user=> (profile (dotimes [i 10000] (my-function 3 4)))

IllegalStateException Can't dynamically bind non-dynamic var: clojure.contrib.profile/*profile-data*  clojure.lang.Var.pushThreadBindings (Var.java:353)

user=> *enable-profiling*

true

my project.clj looks like this

(defproject clam "0.1.0-SNAPSHOT"

  :description "Data description language for parsing text streams"

  :url "https://github.com/mowat27/clam"

  :license {:name "MIT Licence"

            :url "http://copyfree.org/licenses/mit/license.txt"}

  :dependencies [[org.clojure/clojure "1.4.0"]

                 [org.clojure/clojure-contrib "1.2.0"]

                 [midje "1.4.0"]

                 [com.stuartsierra/lazytest "1.2.3"]]

  :repositories {"stuart" "http://stuartsierra.com/maven2"})

Thanks very much

Adrian

clojure.contrib is not supported in clojure versions 1.3+
The reason in this case is that in 1.3+, it is necessary to add ^:dynamic or ^{:dynamic true} in the def form (i.e. to the metadata)
for the var to be dynamically changed with bindings.

Fixed clojure.contrib.profile:

You are running clojure 1.3 or greater with the pre-1.3 contrib.

Since 1.3, contrib has been split in separate libs, you can find where the
different parts have moved here;

http://dev.clojure.org/display/design/Where+Did+Clojure.Contrib+Go

The profiling stuff did not make it it seems. A java profiler would be your best bet.

There is a 1.3 compatible monolithic contrib out there but I would not bundle it
as a standard dependency. The new libs are moving forward faster now that they
can be delivered individually.

I cannibalized most of the old contrib profiling stuff for Timbre, btw: https://github.com/ptaoussanis/timbre#profiling

@odyssomay, @Luc thanks very much.  That explains the problems I was having
