Description
This PR contains the final bit of refactoring before I start fixing the import problems mentioned in #5498.
The semantics of imports has so far been implemented in the
Module
struct, and has assumed that the destination path of an import was relative toself
. In particular, this allows imports to any submodule of the current module.However, whenever that logic was triggered by the compiler the destination path was always absolute. The only reason this worked was that the logic was only ever triggered on the root module.
To reflect this behavior I have therefore moved the import semantics to the
Root
struct, and made it clear in the comments that the paths are assumed to be absolute.This also reflects the fact that once the module structure has been populated with the imported entities we don't actually need the import logic anymore, so it shouldn't be located in the
Module
struct. (Name resolution should obviously stay in theModule
struct, so that logic has not been moved).I have left a couple of TODOs in the code to remind myself where I need to make changes when I start implementing
pub use
(see #3113 ).Checklist
