Add unix socket #158

cecton · 2021-11-17T18:21:27Z

Linking this issue here as these traits could be moved to tokio-util: ~~tokio-rs/tokio#4244~~ tokio-rs/tokio#4385

It's working!

This looks super cool! is there any issue / context this pr refers to ?

EDIT: my bad, i didn't notice #154 below

I added it after I requested your review lol

This looks super cool!

Actually it's terrible xD There should be a way to get a listener that is either a unix socket or a tcp listener. I made a PR to add that to tokio-util 🤞

o0Ignition0o

Wow this is great work! 🎉 the pull request reads incredibly well!

+1 for me, with only one question / comment.

Pre-approving this, although we might want to wait a bit and see if the tokio team wants to accept the listener trait.

Yes I would too but I expect this to take some time. The current implementation is quite easily replaceable so I wouldn't mind merging this for now.

crates/apollo-router/src/http_server_factory.rs

+pub(crate) type BoxAsyncReadWrite = Box<dyn AsyncReadWrite + Send + Unpin + 'static>;
+
+impl AsyncReadWrite for TcpStream {
+    fn set_nodelay(&self, nodelay: bool) -> io::Result<()> {


this should be done right at socket creation, there's no need to add an empty method for UnixStream

Outdated, I do not touch that part anymore

crates/apollo-router/src/http_server_factory.rs

+    fn set_nodelay(&self, nodelay: bool) -> io::Result<()>;
+}
+
+pub(crate) type BoxAsyncReadWrite = Box<dyn AsyncReadWrite + Send + Unpin + 'static>;


it's not a good idea to have a Box<dyn> to hold either a TcpStream or UnixStream. It is useful when we're handling both kinds of objects at runtime, but here we're always creating one kind of object (we won't run in TCP and Unix socket modes at the same time), so we should not bear the cost of adding an allocation in the hot path for that.
AsyncRead has one method, AsyncWrite has 5 methods, so it's still reasonable to make an enum here.

Fixed with new impl
