How to control the retry function

[ci010]

I've read some discussions (#1195) and issues, which said undici currently has retry function for socket error.

I just wonder if we can config the retry gap and limit? How does the retry works with timeout?

It seems there is no a explict place for retry code. I guess the current implementation is in client.js?

async function fetch_retry (url: URL, options: RequestInit, timeout: number, retries = 0, count = 0): Promise<Response> {
    try {
        options.signal = AbortSignal.timeout(timeout)
        return await fetch(url, options)
    } catch (error) {
        if (
            count >= retries ||
            error.name !== 'TimeoutError' && !['ECONNRESET', 'ETIMEDOUT', 'ESOCKETTIMEDOUT'].includes(error.cause?.code)
        )
            throw error
        else {
            const duration = 2 ** count
            console.log(`${`wait ${duration} seconds to retry fetching (${count}) …`.yellow}  ${url.toString().blue.underline}`)
            await delay(1000 * duration)
            return fetch_retry(url, options, timeout, retries, count + 1)
        }
    }
}
