Problem: -------- I have a launchd daemon that performs DNS requests using getaddrinfo to retrieve the IP(s) for a series of hosts' names.
• On Yosemite: The requests all fail (EAI_NONAME) when they are run just after the daemon has been launched. They also fail 1 minute later. They again fail 1 minute later. And they again fail 1 minute later. Killing the process via Activity Monitor (*) automatically restarts the daemon as expected. And then the requests that should succeed do succeed on the first attempt. Also if you were to perform a nslookup (from the Terminal) query during that time with the same hosts' names, it would work fine. • On Mountain Lion: The requests that should succeed do succeed. At least on the computer I used. Discussion: ----------- I could understand that just after boot time the DNS APIs would not be ready. I can not understand why they still do not work 3 minutes after startup time. Question: --------- What could prevent the getaddrinfo from working? Could it be some mach bootstrap context issue? According to the doc, this API is supposed to be thread safe. A hostname is correctly provided, a hints structure is provided (using NULL does not solve the issue). (*) I'm wondering whether it's the designed behavior of Activity Monitor that you can force kill a root process without having to enter your admin password. _______________________________________________ Do not post admin requests to the list. They will be ignored.
