Summary
import/namespacepanicked (aborting the lint run) when object-pattern destructuring recurses into a namespace whose remote module is unresolvable.Problem
For
import * as a from "./m"; var {ns:{x}} = awheremdoesexport * as ns from './unresolvable',check_deep_namespace_for_object_patternfindsnsamong the export entries (get_module_request_namereturns the request), then callsmodule.get_loaded_module(request).unwrap(). Unresolvable modules are never inserted intoloaded_modules, soget_loaded_modulereturnsNoneand.unwrap()panics. The siblingcheck_deep_namespace_for_nodealready handles the same situation with?.Fix
Replace
.unwrap()with alet Some(..) else { continue }guard, skipping the unresolvable namespace exactly like the node path does.Testing
fixtures/import/unresolvable-namespace.js(export * as missing from './does-not-exist') and a pass caseimport * as a from "./unresolvable-namespace"; var {missing:{x}} = a. Reverting the fix makes this case panic atnamespace.rs:329(Option::unwrap()onNone); with the fix it lints cleanly.cargo test -p oxc_linter --lib rules::import::namespaceandcargo lint -- -D warningspass.
