2.3.36 on FreeBSD 6.2-STABLE.
We have a need for the client to detect a hung server, so I thought I'd
try something like this, called before each new connection:
struct timeval tv;
tv.tv_sec = 5;
tv.tv_usec = 0;
ldap_set_option(ld, LDAP_OPT_TIMEOUT, &tv);
ldap_set_option(ld, LDAP_OPT_NETWORK_TIMEOUT, &tv);
(In the actual code I do test for errors.)
I then ran "nc -l 389" to simulate a hung server, and issued a search
against it, but it never times out. Attaching to the client with GDB and
getting a back-trace shows this:
(gdb) bt

#1 0x280dfca9 in ldap_int_select () from /usr/local/lib/libldap-2.3.so.2
#2 0x280d00d0 in ldap_result () from /usr/local/lib/libldap-2.3.so.2

host=0x804b520 "") at getporthost.c:200
#5 0x08048e8c in main (c=1, v=0xbfbfe840) at main.c:50
Do timeouts actually work? If so, what have I misunderstood?
