Abstract

Add a mechanism to disable the default import callback when using the native binary.

Motivation

The native binary defaults to the Host Filesystem Loader, meaning that JSON inputs that are not self-contained can still compile fine. This is a problem for Hardhat because we want to get an error in those cases.

There is a workaround: creating an empty temporary directory and using it with --base-path. But having a specific flag like --no-import-callback would be much better.

Specification

Add a --no-import-callback to the solc binary that disables any default import callback.

Backwards Compatibility

This is a new flag so there shouldn't be backwards compatibility issues.
