I suppose we could reach 100% free by making the function also handle sorting and limiting, though that could be overkill. + +---- + +Found a further complication in presence dependencies. Map now uses +presence dependencies when adding its explicit dependencies on pages. But +this defeats the purpose of the explicit dependencies! Because, now, +when B is changed to not match a pagespec, the A's presence dep does +not fire. + +I didn't think things through when switching it to use presense +dependencies there. But, if I change it to use full dependencies, then all +the work that was done to allow map to use presence dependencies for its +main pagespec is for naught. The map will once again have to update +whenever *any* content of the page changes. + +This points toward the conclusion that explicit dependencies, however they +are added, are not the right solution at all. Some other approach, such as +maintaining the list of pages that match a dependency, and noticing when it +changes, is needed. |
