Re: getaddrinfo() starts failing with EAI_AGAIN. Libinfo-278 build fails: ../include/DSmemberdMIG.defs: No such file or directory

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Thanks for the quick response, Paul > 1. Use tcpdump to find out why your dns server is not on the net I'm now running: tcpdump -i en0 udp dst port 53 or udp src port 53 and have modified the child script to call: host thehostname nslookup thehostname ping -c1 thehostname svn thehostname So I'd still like to try and debug getaddrinfo() ... Thank you Peter (where thehostname is an unqualified hostname of another machine on the same subnet) with a "sleep 5s" between each to, help me match up the commands and their traffic by time. tcpdump displays: - for host: requests and responses, and the command succeeds - for nslookup: a request and response, and the command succeeds - for ping and svn, however tcpdump is silent and the commands fail. Is my tcpdump invocation correct - or is this expected? Next I ping the same unqualified host name from an unrelated bash shell, but as the same user, on the same machine: ping works - (though tcpdump is silent - because getaddrinfo() has cached the address?). >From that unrelated process, if I ping an imaginary hostname, tcpdump does show the request and response, but only the first time per hostname. Next I tried inserting pings to imaginary hosts in the shell script, to be called by the long-running process - these DNS lookups are also not shown by tcpdump. If my tcpdump invocation is correct, and there is only one ethernet port (en0) and no wireless/alternative interfaces: it looks like getaddrinfo() - under children of my long-running- process - at some stage started failing with EAI_AGAIN before/without sending a DNS lookup for either a previously used host *or* a unique imaginary one. > You may have a problem where a daemon starts and calls res_init before /etc/resolv.conf is written properly To clarify, my long running process was started by hand long after the system booted, rather than on init, so I think that /etc/resolv.conf would have been written properly already - unless something else rewrites it periodically?

And I think that's a perfectly fair request and certainly easier for us [Apple] than creating new API in those cases where the design and sustainability of said API isn't clear at all. Do you have a radar filed against the ASP folks to document the output of system_profiler(8)? While we're on the subject of API that isn't particularly well- designed or sustainable... If anyone has any ideas on how to replace (or supplement) sysctl(3) with something that overcomes all its obvious warts without also causing people to scream "Aaaaah! It's the Windows Registry! Ported over here to kill us all!", I'm all ears (or eyeballs). Terry and I are both old enough to remember the genesis of sysctl(3) in BSD as a "small number of simple knobs" mechanism and we both know that what we have today represents an over-usage of it to the point that it's been stretched well beyond its original design goals. It represents a problem to be fixed, and one that could conceivably be fixed in any number of ways, which is in itself a problem: Which is the "right" way? One obvious idea is to start with the new DSLocal store and make it a type of directory service, but there's a few non-obvious steps between there and step 3, Profit!, including the staying-away-from-the-Windows- Registry one mentioned earlier. Other, better, ideas may be less obvious to me. This email sent to site_archiver(a)lists.apple.com
