This removes the global mutable execution options and replaces them with a node context parameter:
context: NodeContext
.The new parameter is opt in and can be enabled in
@register
with thenode_context
property. This not only minimizes the diff (I didn't want to change all nodes), it might also enable optimizations in the future.Right now, the
NodeContext
class has 2 aspects to it: settings and progress. Settings and other execution options are now accessed through the node context parameter. While only the settings aspect is currently used, I also laid the groundwork for per-node progress, which will be my next goal.
