maxConnectionRetryCount: 0 is coerced to 1

[yeongseon]

Summary

Passing maxConnectionRetryCount: 0 does not disable retries. The constructor coerces 0 to 1, so the client always retries at least once.

Reproduction

cd /data/GitHub/node-cubrid
node - <<'NODE'
const CUBRID = require('./');
const client = new CUBRID.createConnection({ hosts:['localhost'], maxConnectionRetryCount: 0 });
console.log(client.maxConnectionRetryCount);
NODE

Actual

The script prints 1.

Expected

The script should print 0, so callers can explicitly disable retry loops.

Likely cause

src/CUBRIDConnection.js initializes the field with:

this.maxConnectionRetryCount = maxConnectionRetryCount || 1;

That treats 0 as missing input.

Suggested fix

Use nullish handling instead of ||, for example:

this.maxConnectionRetryCount = maxConnectionRetryCount ?? 1;

or an equivalent explicit undefined check.
