[FR]: Switch all exec calls to proc_open

[rungta]

Could the exec calls in the code base be switched to proc_open for wider compatibility with systems where exec is disabled (and better security?)?

@rungta I think really what should happen is they should all be switched over to use the ::executeShellCommand() which does exactly that:

    protected function executeShellCommand(string $command): string
    {
        // Create the shell command
        $shellCommand = new ShellCommand();
        $shellCommand->setCommand($command);

        // If we don't have proc_open, maybe we've got exec
        if (!\function_exists('proc_open') && \function_exists('exec')) {
            $shellCommand->useExec = true;
        }

The good news is that there are only 3 places where exec() is used directly, so this shouldn't be bad to do.

I take it back, it's not a simple swap-out because exec() returns an array, and the shellCommand returns a string.

Yeah, I assumed there must’ve been a good reason why it wasn’t already making use of `executeShellCommand`. My experience with both these functions is fairly limited though, so not sure of the intricacies.
