  • fix handling of build dependencies with # in path

Performance

  • improve memory usage when using the filesystem cache

When reading a file into a Buffer and picking smaller slices of the Buffer the small slices still keep a reference to the large original Buffer. The leads to increased memory usage. A fix would be to clone the slice into a smaller Buffer when wasting too much memory, but this has a performance cost. There is now a new option cache.allowCollectingMemory which controls that. For one-off builds you probably want allowCollectingMemory: false and for watch builds you probably want allowCollectingMemory: true. It defaults to false in production mode and true in development mode.
