I am not sure if this is a problem unique to me or not but under
10.5 [[NSHost currentHost] name] or [[[NSProcessInfo] processInfo]
hostname] were quick and easy ways to get an mDNS friendly hostname
such as imac-2.local
On 10.6 I find that both these combinations block badly
(NSProcessInfo merely defers to NSHost I think).
The list has a few references to the possibility of these blocking
but I never encountered it until now.
According to a stack sample getnameinfo() seems to be the library
call that is blocking.
_mdns_query_mDNSResponder seems to be the actual blocking call.
Anyone else seeing this behaviour?
It's a system wide problem (try to launch OpenGL Profiler for
instance, it take hours).
But it occurs only with some specifics networks configuration.
I had thought that there had to be some local configuration aspect to
it. Connecting to other .local machines is none too swift on occasion.
Do you have "Internet Sharing" enabled ? That's what causing the
issue on my machine.
Yes I do - though I don't recall enabling it or needing it.
The machine was upgraded from 10.5 and the blocking behaviour before
went completely unnoticed.
Switching to SCDynamicStoreCopyLocalHostName() has greatly reduced the
apps launch time.
