** Description changed: Binary package hint: nginx As describe at: http://nginx.org/pipermail/nginx/2010-December/024229.html --- In ngx_inet.c, there is a code piece of function "ngx_inet_resolve_host". If I set u->one_addr to 1， but unfortunately - this hostname map to multiple IP addresses, such as + this hostname map to multiple IP addresses, such as [code] 10.37.4.92 myhost 127.0.0.1 myhost [/code] in /etc/hosts. h->h_addr_list will be 2 entries before NULL. Each of them will be converted to human readable format and assigned to u->addrs[ i ]. However, when one_addr is set, [b]u->addrs will be allocated ONLY ONE ngx_addr_t mem.[/b] In this way, a mem crash is inevitable. I set one_addr to 1 because I'm writing a custom module and want to connect another server. Sadly the server is also running on the local host with multiple IP in /etc/hosts. I want to connect the first IP match that host name (10.37.4.92) because that server require a non-lookback IP. I thought "one_addr" means "fetch the first found IP". But seems I was wrong. Besides this, I insist alloc mem with "i", but loop will h->h_addr_list is very dangerous. Report an error is more suitable rather than leave a time bomb.
