Nuno Campos 4e373b8af2 Remove noisy frames from stack traces 
- The less frames in library code the less confused the user is
- This doesn't remove all library frames (not possible), but it's a start

Nuno Campos b668bf8eab Rewrite Graph/StateGraph.compile() 
- Each iteration of the graph is one single iteration in Pregel (ie. no more "{node}:edges" nodes)
- .update_state() now acts exactly as one of the nodes in the graph (which can be chosen), which makes human-in-the-loop scenarios where you want to override the actions of a specific node a lot easier to build
- Graph/StateGraph.compile() now delegate adding nodes/edges/etc to dedicated methods that operate on the Pregel object, which is 90% of the way towards dynamic graphs where nodes and edges can be added during execution
 2024-03-31 17:17:18 -07:00
Nuno Campos 4fd90f8ad6 Rename BaseChannel.empty() to BaseChannel.from_checkpoint() 
- clearer name
- channels with complex data structures in checkpoint (eg a set or list) now copy the checkpointed data structures before creating the new channel

Nuno Campos 03b7d6fe0d Remove __end__ node from state graph 
No longer necessary with stream output modes
 2024-03-30 22:04:27 -07:00
Nuno Campos 1ad017781d Add stream_mode=updates or values 
- stream(stream_mode="values") yields thre current channel values whenever a channel is updated
- stream(stream_mode="updates") yields the update sent to each channel by each node
- this removes the __end__ value present at the end of each call to Graph/StateGraph/MessageGraph.stream(). To access the __end__ value either call .invoke() or stream(stream_mode="values")
 2024-03-30 21:24:39 -07:00
Nuno Campos 885e5884c5 Collect pending writes for each node separately 
- ensures that order of updates sent to channels is independent of timing differences when parallel executing multiple nodes
- enables future features
