Description:

I run about 1M+ background processes in a day using background process from a single initiator. Lots of time call_in_background throws "exec() unable to fork" error, though I have set all ulimit as was suggested in forums.

I recommend to implement proc_open instead of exec. Maybe provide this as an optional feature in the code.

Here's what I updated in BackgroundCommand.php, it fixed the issue for me. Ref https://bugs.php.net/bug.php?id=18833

Also if anyone has any idea why exec throws this error on background_call, please let me know :)

...

public function run(& $result,& $status){

        $command = $this->composeCommand();

        $command = is_windows_os()
            ? "start /B {$command}"
            : "({$command}) > /dev/null 2>&1 &";

  
		$process = proc_open(
				$command,
				array(
				0 => array("pipe", "r"), //STDIN
				1 => array("pipe", "w"), //STDOUT
				2 => array("pipe","w")), //STDERR
				$pipes
				);
		$result = stream_get_contents($pipes[1]);
		$error = stream_get_contents($pipes[2]);
		fclose($pipes[1]);
		fclose($pipes[2]);
		$status= proc_close($process);
		$result = explode("\n",trim($result));
	    return($error);
}

При запуске команды call_in_background на Windows выполнение команды не происходит, видимо из-за

protected function composeForRunInBackground()
{
    return "({$this->composeForRun()}) > /dev/null 2>&1 &";
}

Так как разрабатывать и отлаживать приходится в ОС Windows, то это не очень-то удобно.

Hello, I tried using call_in_background() in Lumen, but the command fails because it tries to run it from the /public folder instead of the application root and outputs "Could not open input file: artisan".

I think the function should try to run the command from the app root, not public folder.

Hi,
this is a very good helper function, but i can't make it to work on Laravel 5.5
Calling the call_in_background('UpdateProductPrice:updateproductprice') is not triggering artisan command.
Could you check please and let me know how to debug this ?

Thank you!
