Make git-grep --recurse-submodules stop adding subrepos to the in-memory alternates list and, instead, pass a reference to the subrepo struct down to the threads. This series is based on ew/hashmap (it uses the added container_of macro). There're some possibly needed changes I'm still unsure about. All feedback will be highly appreciated: - textconv cache is written to the_repository's object database even for submodules. Should it perhaps be written to submodules' odb instead? - Considering the following call chain: grep_source_load_driver() > userdiff_find_by_path() > git_check_attr() > collect_some_attrs() > prepare_attr_stack() > bootstrap_attr_stack(): * The last function tries to read the attributes from the .gitattributes and .git/info/attributes files of the_repository. However, for paths inside the submodule, shouldn't it try to read these files from the submodule? * This function will also call: read_attr() > read_attr_from_index() > read_blob_data_from_index() which might, in turn, call read_object_file(). Shouldn't we pass the subrepo to it so that it can call repo_read_object_file()? (Again, for paths inside the submodule, read_object_file() won't be able to find the object as we won't be adding to alternates anymore.)
