Need for a wait_for helper

[jeckel]

Hi there,

When I'm working with docker container for example, I often need to wait that a container is ready (healthy) before processing any other action.

We can think of a helper like this :

/**
 * @param callable(): bool $callback
 * @param int $timeout Maximum number of seconds to wait before throwing a TimeoutException
 * @param int $interval Interval in second between calls to the $callback function
 * @throw TimeoutException
 */
function wait_for(callable $callback, int $timeout = 10, int $interval = 1): void;

If you think it's a good feature, I can try a PR

Or maybe it can return a boolean instead of throwing an Exception ?

Hello,

That could be cool ! I use this pattern too for waiting docker container, or for waiting HTTP service on certain port (+ payload if necessary) to be accessible.

Make this type of helper (docker, network…) as shared castor files in a specific repo when import functions from remote will be OK and merged should be cool :)

I think this is something interesting to add to Castor, so I'm +1 for this. Let's wait for others' feedback 🙂

Good idea
