myapp

A Clojure library designed to demo a potential bug in conman

Usage

git clone https://github.com/dotemacs/maybe-conman-bug
cd maybe-conman-bug
lein deps
lein repl

then in the REPL

(require 'myapp.db :verbose)
(in-ns 'myapp.db)
(mount/start)

and the following error pops up:

IllegalArgumentException Invalid configuration options: (:adapter)
sun.reflect.NativeConstructorAccessorImpl.newInstance0
(NativeConstructorAccessorImpl.java:-2)

Then if I comment out :adapter in pool-spec so that it looks like:

(def pool-spec
  {;;:adapter    :postgresql
   :init-size  1
   :min-idle   1
   :max-idle   4
   :max-active 32
   :jdbc-url "jdbc:postgresql://localhost/myapp"})

eval pool-spec and back in the repl:

(mount/start)

the connection is established just fine:

{:started ["#'myapp.db/*db*"]}
