util.watchdog: Update to use "new" util.timer API When this module was written, it wasn't possible to cancel or reschedule a timer. Times have changed, and we should take advantage of those new methods. This module becomes a very thin wrapper around util.timer now, but I'd argue it's still a very common and useful concept/abstraction to have around. Possible API change: this removes the 'last_reset' field of the watchdog. This was never really intended as a public thing, and I can't find any code that uses it, so I consider removal to be safe.

local methods = {};
local resolver_mt = { __index = methods };
local unpack = table.unpack or unpack; -- luacheck: ignore 113

-- Find the next target to connect to, and
-- pass it to cb()
function methods:next(cb)
	if #self.targets == 0 then
		cb(nil);
		return;
	end
	local next_target = table.remove(self.targets, 1);
	cb(unpack(next_target, 1, 4));
end

local function new(targets, conn_type, extra)
	return setmetatable({
		conn_type = conn_type;
		extra = extra;
		targets = targets or {};
	}, resolver_mt);
end

return {
	new = new;
};
