Only one instance of base_type() getting a NewRef instead of AdoptRef fixed in merge. All other changes are superficial formatting and factoring. * 'leaks' of https://github.com/MaxKellermann/zeek: (22 commits) Stmt: use class IntrusivePtr Stmt: remove unused default constructors and `friend` declarations Val: remove unimplemented prototype recover_val() Val: cast_value_to_type() returns IntrusivePtr Val: use IntrusivePtr in check_and_promote() Val: use nullptr instead of 0 zeekygen: use class IntrusivePtr ID: use class IntrusivePtr Expr: use class IntrusivePtr Var: copy Location to stack, to fix use-after-free crash bug Scope: lookup_ID() and install_ID() return IntrusivePtr<ID> Scope: delete duplicate locals EventRegistry: automatically delete EventHandlers main: destroy event_registry after iosource_mgr zeekygen/IdentifierInfo: delete duplicate fields main: free the global scope in terminate_bro() Scope: pop_scope() returns IntrusivePtr<> Scope: unref all inits in destructor Var: pass IntrusivePtr to add_global(), add_local() etc. plugin/ComponentManager: hold a reference to the EnumType ...
