glue hangs if interface name does not match filename #4050

Closed BrianHicks closed 2 years ago

On 57681be5420586fff80ca6c6f850a9bfc7e6a4c2, given the following files roc glue Package-Config.roc glue.rs will just hang forever.

Package-Config.roc:

platform "roc-lang/rbt"
    requires {} { init : SomeInterface.RecursiveThing }
    exposes [SomeInterface]
    packages {}
    imports [SomeInterface]
    provides [initForHost]

initForHost : SomeInterface.RecursiveThing
initForHost = init

SomeInterface.roc:

interface Rbt
    exposes [RecursiveThing]
    imports []

RecursiveThing : [RecursiveThing Str]

(RecursiveThing is not a great name for this extremely non-recursive type, but I was trying for a different SSCCE when I found this!)

ahhhh, looks like interface Rbt in the filename SomeInterface.roc might be the problem here! But still it hangs forever if the name is wrong.

This just happened to me, and it looks similar to #3440.
