Any method to check if a task is running?

[Pablo-Merino]

Hey! Is there any method to check if my task is running? For example, I have this task:

SHARE_UPDATER_QUEUE = GirlFriday::WorkQueue.new(:share_updater, :size => 7) do |msg|
    Company.update_shares
end

Is there any way I can know (from my model's update_share method) if SHARE_UPDATER_QUEUE is running? Or wait until a task is done to continue processing the rest of the queue?

You can define a callback which is called when a task has completed.

SHARE_UPDATER_QUEUE.push(:some => 'args') do |result|
  # result = result of the last expression in your msg block
end

You can also get GirlFriday.status. But in general, no, there's no easy way to determine runtime status for a queue; performing logic based on that would be full of race conditions.

Thanks for the quick response! I'll just rethink the entire thing so I don't need to check the status 😄

I didn't think the callback was available unless you are using the in-memory store?

Yep, that's true.
