An exception occurs while trying to disable connection retries

[rybakit]

$t = new Tarantool();

ini_set('tarantool.retry_count', 0);

$t->ping();

outputs

Uncaught exception 'Exception' with message '(null)'

Now retry_count option means the following:

• retry_count = 1 — perform only one connection attempt, fail if it is unsuccessful;
• retry_count = N (N >= 2) — perform N attempts to connect and ignore transient errors (connection failures) for the first (N-1) attempts.

So retry_count = 1 is what you want to achieve with retry_count = 0.

retry_count = 0 has no sense and an error should make it clear.

I'm not sure whether we should change meaning of the option (I'm afraid of behaviour changes between versions). I'll update the discussion.

retry_count = 0 has no sense and an error should make it clear.

I would agree with your points if the setting was called number_of_attemps or number_of_tries, but the re prefix already implies that something will be repeated. So it makes perfect sense to me to have retry_count = 0 and in the other thread I gave you examples of well-established APIs that follow this logic. Maybe you have a counterexample? To be honest, I've never seen anything like that before.
