refactoring: Stubbing of the logic for handling moves This is a whole lot of nothing right now, just stubbing out some control flow that ultimately just leads to TODOs that cause it to do nothing at all. My intent here is to get this cross-cutting skeleton in place and thus make it easier for us to collaborate on adding the meat to it, so that it's more likely we can work on different parts separately and still get a result that tessellates.

refactoring: ApplyMoves new return type When we originally stubbed ApplyMoves we didn't know yet how exactly we'd be using the result, so we made it a double-indexed map allowing looking up moves in both directions. However, in practice we only actually need to look up old addresses by new addresses, and so this commit first removes the double indexing so that each move is only represented by one element in the map. We also need to describe situations where a move was blocked, because in a future commit we'll generate some warnings in those cases. Therefore ApplyMoves now returns a MoveResults object which contains both a map of changes and a map of blocks. The map of blocks isn't used yet as of this commit, but we'll use it in a later commit to produce warnings within the "terraform" package.

refactoring: ApplyMoves new return type When we originally stubbed ApplyMoves we didn't know yet how exactly we'd be using the result, so we made it a double-indexed map allowing looking up moves in both directions. However, in practice we only actually need to look up old addresses by new addresses, and so this commit first removes the double indexing so that each move is only represented by one element in the map. We also need to describe situations where a move was blocked, because in a future commit we'll generate some warnings in those cases. Therefore ApplyMoves now returns a MoveResults object which contains both a map of changes and a map of blocks. The map of blocks isn't used yet as of this commit, but we'll use it in a later commit to produce warnings within the "terraform" package.

refactoring: ApplyMoves skips moving when destination address occupied Per our rule that the content of the state can never make a move statement invalid, our behavior for two objects trying to occupy the same address will be to just ignore that and let the object already at the address take priority. For the moment this is silent from an end-user perspective and appears only in our internal logs. However, I'm hoping that our future planned adjustment to the interface of this function will include some way to allow reporting these collisions in some end-user-visible way, either as a separate warning per collision or as a single warning that collects together all of the collisions into a single message somehow. This situation can arise both because the previous run state already contained an object at the target address of a move and because more than one move ends up trying to target the same location. In the latter case, which one "wins" is decided by our depth-first traversal order, which is in turn derived from our chaining and nesting rules and is therefore arbitrary but deterministic.

refactoring: ApplyMoves new return type When we originally stubbed ApplyMoves we didn't know yet how exactly we'd be using the result, so we made it a double-indexed map allowing looking up moves in both directions. However, in practice we only actually need to look up old addresses by new addresses, and so this commit first removes the double indexing so that each move is only represented by one element in the map. We also need to describe situations where a move was blocked, because in a future commit we'll generate some warnings in those cases. Therefore ApplyMoves now returns a MoveResults object which contains both a map of changes and a map of blocks. The map of blocks isn't used yet as of this commit, but we'll use it in a later commit to produce warnings within the "terraform" package.

refactoring: exhaustive NestedWithin checks When checking dependencies between statements, we need to check all combinations of To and From addresses.

refactoring: Stubbing of the logic for handling moves This is a whole lot of nothing right now, just stubbing out some control flow that ultimately just leads to TODOs that cause it to do nothing at all. My intent here is to get this cross-cutting skeleton in place and thus make it easier for us to collaborate on adding the meat to it, so that it's more likely we can work on different parts separately and still get a result that tessellates.
