How to pause a queued job on graceful shutdown & resume afterward?

[a-h-abid]

I'm looking for ways to pause a job whenever the Queue worker (daemon) receives the shutdown signal (SIGTERM). Specially in a long running job where I need the job to resume from the part it stopped instead of starting from beginning. Say for the below code, how can I pause & resume the queued job ??

I tried with the App::terminating, but it did not worked. Using the pcntl_signal doesn't works this way queue worker's own graceful shutdown gets broken.

Any help will be appreciated.

<?php

namespace App\Jobs;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Cache;
use Illuminate\Support\Facades\Log;

class DummyJob implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    protected $shouldStopJob = false;

    public function handle()
    {
        Log::info('Attempt: ' . $this->attempts());
        Log::info('MaxTrys: ' . $this->job->maxTries());
        Log::info('Timeout: ' . $this->job->timeout());

        $i = Cache::get('dummy.loop-no', 0);
        $done = 60;
        if ($i >= $done) {
            Log::info("No need to proceed!");
            return;
        }

        App::terminating(function () {
            Log::info('App Terminating');
            $this->shouldStopJob = true;
        });

        pcntl_signal(SIGTERM, function () {
            $this->shouldStopJob= true;
        });

        for (; $i < $done; $i++) {
            Log::info("Loop no. #{$i}");

            sleep(1);

            Cache::put('dummy.loop-no', $i, now()->addSeconds(60));

            if ($this->shouldStopJob) {
                Log::info("Stopping!");
                $this->job->release(10);
                break;
            }
        }

        if ($this->shouldStopJob) {
            return;
        }

        Log::info("Done!");
        Cache::forget('dummy.loop-no');
    }
}

Why not look at this value instead of this->shouldStopJob?
app('queue.worker')->shouldQuit

I'd be happy to help.

Oh ... thats a good idea. app('queue.worker')->shouldQuit is a public property and I can make use of it instead of my own.

Thanks a lot!
