Comment #9 on issue 1853 by
[hidden email]: NetNameResolver
localHostAddress returns public or private address instead of loopback
address.
http://code.google.com/p/pharo/issues/detail?id=1853It's much slower on Unix than what you'd see on Mac or Windows because....
/* Note: the Mac and Win32 implementations implement asynchronous lookups
* in the DNS. I can't think of an easy way to do this in Unix without
* going totally ott with threads or somesuch. If anyone knows differently,
* please tell me about it. - Ian

/*** irrelevancies ***/
void sqResolverAbort(void) {}
void sqResolverStartAddrLookup(sqInt address)
{
const char *res;
res= addrToName(address);
strncpy(lastName, res, MAXHOSTNAMELEN);
FPRINTF((stderr, "startAddrLookup %s\n", lastName));
}
Note how the ResolverSemaphore isn't signaled?
So it ALWAYS waits for the deadline when doing address lookup in:
NetNameResolver class >> #addressForName: timeout:
"snip"
deadline := Time millisecondClockValue + (secs * 1000).
"Protect the execution of this block, as the ResolverSemaphore is used for
both parts of the transaction."
self resolverMutex
critical: [
(self waitForResolverReadyUntil: deadline)
ifTrue: [
self primStartLookupOfName: hostName.
(self waitForCompletionUntil: deadline)
Yay.
