:production profile two ways

[ccfontes]

Currently, what's the correct way to configure the :production profile?

As is in this repo's readme.md

:production {:app-specific "config"
             :mirrors {"central" "http://s3pository.herokuapp.com/maven-central"}}

web: lein with-profile offline,production trampoline run -m myapp.web

or?

as is on heroku dev center

:production {:misc "configuration" ; app-specific stuff
             :offline true
             :mirrors {#"central|clojars"
                       "http://s3pository.herokuapp.com/clojure"}}

web: lein with-profile production trampoline run -m myapp.web # 2.x

I'm struggling with dependencies in production on heroku:

2013-06-19T18:44:47.583418+00:00 app[web.1]: Performing task 'trampoline' with profile(s): 'offline,production'

:production profile:

:production {:app-specific "config"
                :mirrors {#"central|clojars"
                            "http://s3pository.herokuapp.com/clojure"}}

Tried a number of combinations, but without much success. Those two artifacts are very recent, and one of them is critical. Is it possible the mirror repo isn't updated recently, and if so, is it possible to update it soon?

Sorry you're having trouble here. Using this mirror for Clojars turned out to not be a great idea, and the buildpack was updated, but the docs were not, so thanks for catching this. I'll update the devcenter.

If the mirror is giving you trouble you can remove it from the production profile altogether to debug too.

[ccfontes]

I removed the mirror altogether for debugging purposes. Profile is like this:

:production {:app-specific "config"}

Now I have alot of artifacts missing. I guess the previously configured mirror was providing some artifacts.

Some suggestions:

• If the problem is about the mirror not being up to date, Isn't it possible to update the mirror more often? Most people have a staging environment anyway, so even if an error occur at that point, it's doable to wait some minutes or even a couple of hours so the mirror syncs with a main repo.
• falling back to "online" when an artifact is not found, and hope that it doesn't trigger the boot timeout (at the same time syncing that artifact to the mirror).
• falling back to "online" when an artifact is not found, and for each artifact that is fetched online, do not count that time for the boot timeout. (maybe this policy override is not possible from the buildback).

Finally, if the mirror is not a choice anymore, which is or will be to prevent the dreaded boot timeout error?

If dependency resolution is happening at app boot time, that's a problem. Dependencies should be resolved only during build time.

I've just pushed a change that disables the offline behaviour in the production profile. I've been making some changes on the uberjar branch; I'm thinking in the future I'll start recommending using Leiningen only during deployment and putting direct java invocations in the Procfile. If you want to try out the uberjar branch you can do so by setting BUILDPACK_URL=git://github.com/heroku/heroku-buildpack-clojure.git#uberjar and changing your Procfile entry as the readme describes there. It's much easier to avoid this kind of issue if you use Leiningen only for deploying and not at runtime. I'd be interested in any feedback you have on that if you try it.

[technomancy]

If that doesn't take care of things feel free to email me with your app name and I can take a closer look.

"...and changing your Procfile entry as the readme describes there..."
Procfile in the readme still uses offline behaviour.

I'm using PATH as you told me:

PATH=.lein/bin:/usr/local/bin:/usr/bin:/bin JAVA_OPTS="-Xmx500m -Duser.home=$BUILD_DIR" lein uberjar 2>&1 | sed -u 's/^/       /'

I also have enviroment PATH defined in heroku with the exact same value.

[technomancy]

I can't tell what's going on from your comment; if you email me your app name I can take a closer look.

[ccfontes]

The push was rejected, so the above changes are not included. Hope this isn't a problem. Emailing.
