Alexei,
Unfortunatelly this patch didn't help. Because system have already
returned host name as "nstdrlew21.ins.intel.com".
Certainly we can hardcode 127.0.0.1 as localhost
if (address == 0x7f000001) {
hostName = "localhost";
} else {
hostName = getHostByAddrImpl(ipaddress).hostName;
// ask system
}
and we will get on Harmony
by name (127.0.0.1) -> localhost
by name (localhost) -> localhost
by address -> localhost
localhost -> nstdrlew21/10.125.122.60
But I am not sure this is correct.
2006/10/19, Fedotov, Alexei A <[EMAIL PROTECTED]>:
Denis,
Can we consider a patch from
http://issues.apache.org/jira/browse/HARMONY-73 as a fourth option?
Simply speaking, the patch adds a conditional operator which forces API
to returning "localhost" in this case.
Paulex,
This is your patch. What do you think?
With best regards,
Alexei Fedotov,

>Actually Harmony use native call of getnameinfo() to get host name
>(which is reasonable IMHO). MSDN says "The getnameinfo function
