I agree being noisy about early failures when we succeed later is a bad
thing. But when we fail completely, doesn't your code now mask early
failures and print only the final one? The early failures might be the
important ones for the user.
So perhaps we should do something instead like:
struct strbuf error_message = STRBUF_INIT;
...
if (connect(...) < 0) {
strbuf_addf(&error_message, "%s[%d: %s]: errno=%s\n",
host, cnt, ai_name(ai), strerror(errno));
...
}
if (sockfd < 0)
die("unable to connect to %s:\n%s", host, error_message.buf);
strbuf_release(&error_message);
