3. Provide a description of the PR(e.g. more details, effects, motivations or doc link):

  1. resolver cache clear impl bug. Insert pkgpath in to invalidated_set while cause line 616 always be true and the rest of this function will never be executed. It will pop_front and continue until the queue is empty.
if invalidated_set.contains(&cur_node.pkgpath) {
       continue;
}
  1. fix: fix parse cache. First update all AST information. When constructing pkg recursively, it will try to get AST information from the cache(line 382 self.load_import_package()). In the previous implementation, the old version of AST was obtained in recursion, and then the new version of AST was added to the main package, resulting in inconsistent AST versions of the same file in the main package and other pkgs.
