Alex Crichton (Sep 28 2023 at 22:58): Alex Crichton (Sep 28 2023 at 22:58):For those interested I've posted an initial implementation of the ip-name-lookup interface to https://github.com/bytecodealliance/wasmtime/issues/7070. The implementation and tests are pretty bare bones for now as I mostly wanted to set up the plumbing of types and bindgen and all that.
@Badeend (sorry for the ping both on github and here) I suspect you have an implementation already in mind and/or a test suite already in mind, and I'd be happy to switch implementations and/or fill out tests as well, so was wondering if you do indeed already have these things in mind to share here. If not, no worries!
kellytk (Oct 11 2023 at 03:15):I'm developing a tool which will perform DNS lookups. I could write it directly in Rust, however I'd like to target a wasm+wasi environment if possible. I require two features: 1. To resolve name => [ipv4|6] address(es), 2. To obtain the associated TTL for the record. Will both be offered by Preview 2?
Alex Crichton (Oct 11 2023 at 05:05):Currently wasi:sockets/ip-name-lookup can perform translation to ip addresses, but I don't believe it currently has information about TTL. If you're interested in that I think it'd be good to open an issue on the wasi-sockets repository
kellytk (Oct 11 2023 at 17:49):https://github.com/WebAssembly/wasi-sockets/issues/65#issuecomment-1757809815 provided an update and answer to my feature request. ""TTL" is a concept specific to DNS and ip-name-lookup is not a DNS API."... "If you need access to the TTL value, the only option available in WASI right now is to perform the UDP communication yourself."
