Emails not delivered in development unless queue jobs is unselected

On the latest master branch, emails are not being delivered in my local development environment unless I deselect the ‘queue jobs’ site setting. If I execute the job from the console it still works as expected. If I check out an earlier version it also works as expected. I’m not sure what is going on with this.

This is by design, see:

github.com/discourse/discourse

lib/demon/sidekiq.rb

main


      
          # By default Sidekiq does a heartbeat check every 5 seconds. If the processes misses 20 heartbeat checks, we consider it
          # dead and kill the process.
          SIDEKIQ_HEARTBEAT_CHECK_MISS_THRESHOLD_SECONDS = 5.seconds * 20
          
          def self.heartbeat_check
            sidekiq_processes_for_current_hostname = {}
          
            Sidekiq::ProcessSet.new.each do |process|
              if process["hostname"] == HOSTNAME
                sidekiq_processes_for_current_hostname[process["pid"]] = process
              end
            end
          
            Demon::Sidekiq.demons.values.each do |daemon|
              next if !daemon.already_running?
          
              running_sidekiq_process = sidekiq_processes_for_current_hostname[daemon.pid]
          
              if !running_sidekiq_process ||
                   (Time.now.to_i - running_sidekiq_process["beat"]) >
                     SIDEKIQ_HEARTBEAT_CHECK_MISS_THRESHOLD_SECONDS

In particular launch sidekiq with:

bin/sidekiq -q critical -q default -q low

The reason this stopped working is that you are only starting a “default” queue by default and lots of emails actually get queued in the “critical” queue and “low” queue.

Perhaps a PR to update any dev guide out there?
