The steps in this iteration makes this move much less confusing to me than in the previous one. We used to call one of "handle path with/without trailing slash" functions and then called the invalidation. Now the invalidation happens in these "handle path" functions. The unexplained change in behaviour is that we used to do the rest of "handle path" and invalidation was done at the end. Now we do it upfront. I think the "rest" works solely based on what is in the main in-core index array (i.e. the_index.cache[] aka active_cache[]) and affects only what is in the in-core index array, while untracked_cache_invalidate*() works solely based on what is in the untracked cache extension (i.e. the_index.untracked) and affects only what is in there, so the order of these two does not matter. Am I correct? Or does it affect correctness or performance or whatever in any way? IOW, is there a reason why it is better to do the invalidation first and then doing the "rest" after (hence this patch flips the order of two to _improve_ something)? Thanks.
