Cannot load daemon

See my note on pull request #12 :

The log file is still created with a leading : on it. This line should call name on alias I think: https://github.com/arohner/lein-daemon/blob/master/src/leiningen/daemon.clj#L63

The do-start function does not have the args passed to it from start-main so any additional arguments are ignored.

I was using keywords previously but when I upgraded to 0.5.1, I got a null pointer on the (symbol (:ns info)) call because passing :foo as the daemon name seemed to just create a ":foo" string which failed to match on the get-in call that gets the daemon info from the project.

When I changed to using strings in the :daemon map and passing foo as the daemon name, everything worked fine.

The readme is a bit confusing on this since it shows keywords in the :daemon map but also shows lein daemon start foo (not a keyword) later on. For me, the latter did not work when the :daemon map contained keywords.

Not sure whether this is a bug or a documentation issue?

If you configure your pidfile to be located anywhere outside of the project directory (for instance, /tmp/app.pid), the startup script will hang indefinitely waiting for the pidfile to appear, even though the pidfile has been created correctly.

When project.clj defines :main its value could be used as an implicit default configuration. It would remove the need for the :daemon configuration for simple project.
Also it could be manipulated without key e.g. lein daemon start

What do you think?

Any reason there isn't a restart task? Would you object to a PR?

Ahoy!

I'm a hapless operations guy tinkering with Clojure. As an Ops guy lein-daemon is the bee's knees!

I'm working on a learning project here and I am getting the following when I try to daemonize my leiningen project:

I have in my project.clj:

  :dev-dependencies [[lein-daemon "0.4.0"]]

and

  :daemon {:crybaby {:ns crybaby.core
                     :pidfile "run/crybaby.pid"}}

I am working in Ubuntu 12.04, Clojure 1.4.0 and Leiningen 1.7.1 on Java 1.6.0_24 OpenJDK 64-Bit Server VM.

I must be overlooking some mundane detail, but I haven't quite gotten the knack for parsing Clojure stack traces...

Have you any thoughts?

https://github.com/arohner/lein-daemon/blob/master/src/leiningen/daemon_starter.clj#L12
The value of alias in the above line is not keyword, but string.
So retrieving daemon map always fail.

Right now it's set to 5 minutes, but I have a project that is timing out. I've noticed that lein trampoline can take awhile compared to lein run in my case. If this could be a setting specified in :daemon in project.clj it would be helpful as I could extend it. Also those who want a shorter timeout can do that too.

As a workaround for anyone having timeout issues, you can run nohup bash -c "lein trampoline run", but you'll need to kill it off manually.

I don't want to put my source code on server, is it possible to put the lein daemon logic in the -main method?
