Add environment variable to turn off recurring jobs

[daniel-nerdgeschoss]

Hello, thank you for Solid Queue!

We're in the process of migrating an older app form Sidekiq to Solid Queue. We're using Heroku Review apps, and we don't want any recurring jobs to run there. It would be nice if we could completely skip recurring tasks by setting an environment variable.

In searching for a workaround, I found that I could make it work if I added this line to bin/jobs:

  require_relative "../config/environment"
  require "solid_queue/cli"

+ ARGV << "--skip-recurring" if ENV["SOLID_QUEUE_SKIP_RECURRING"]

  SolidQueue::Cli.start(ARGV)

(This is of course not the right way to add this, but as a workaround, it's okay.)

Is an option like this something you'd be interested in? I could try to implement it properly, similar to how the SOLID_QUEUE_RECURRING_SCHEDULE environment variable works, and send a PR.

Thank you again!

Hey @daniel-nerdgeschoss, sure thing! Feel free to open a pull request for this.

I wonder, however, whether it'd be sufficient for you to call bin/jobs like this:

bin/jobs --skip-recurring

Or do you really need the environment variable rather than the command-line option?

Hey @rosa, thanks for the positive reply! I will take a look when I find the time.

Sadly, adding the flag is not quite sufficient because in Heroku, you can only set one Procfile for all environments, which looks like this:

web: bin/rails serve
worker: bin/jobs
release: bin/rails db:migrate

This file is used for Production, Staging, and Review Apps – so the flag would either always be set, or never. The best way to be environment specific in Heroku is … to use environment variables. :D
