This is a backport of https://github.com/sbt/zinc/pull/87 When `B2.scala` replaces `B.scala` in the new test `types-in-used-names-a`, the name hash of `listb` does not change because the signature of `C.listb` is still `List[B]`, however users of `C.listb` have to be recompiled since the subtyping relationships of its type have changed. This commit does this by extending the definition of "used names" to also include the names of the types of trees, even if these types do not appear in the source like `List[B]` in `D.scala` (since `B` has been invalidated, this will force the recompilation of `D.scala`). This commit does not fix every issue with used types as illustrated by the pending test `types-in-used-names-b`, `B.scala` is not recompiled because it uses the type `T` whose hash has not changed, but `T` is bounded by `S` and `S` has changed, so it should be recompiled. This should be fixable by including the type bounds underlying a `TypeRef` in `symbolsInType`. The test `as-seen-from-a` that did not work before shows that we may not have to worry about tracking prefixes in `ExtractAPI` anymore, see the discussion in sbt/zinc#87 for more information. |
