Sydney RunkleandGitHub 19ca6b416b fix: post_model_hook should inject state + store into tool calls if necessary (#4842) 2025-05-27 17:42:20 +00:00
Nuno Campos 936176eb21 Remove Checkpoint.writes 
- This has been superseded by saving the individual writes of each task through put_writes()
- Removing this speeds up checkpoint operations as it was duplicating data saved elsewhere already
 2025-05-25 19:06:46 -07:00
Nuno Campos 4e8fbe4525 Remove Checkpoint.pending_sends 
- Instead store sends in a Topic channel, removing the need to fetch sends as writes against the parent checkpoint
- Remove deprecated/unused functions in langgraph-checkpoint (will require bumping min range for langgraph-checkpoint in langgraph lib)
- Implement migration of old pending sends in langgraph-checkpoint-postgres
- Ensure parent config of `checkpoint_during=False` checkpoints always points to checkpoints that were also saved
 2025-05-25 19:06:02 -07:00
Nuno Campos 85522ec6a6 Pregel: Add NodeBuilder class to replace Channel.subscribe_to 
- For now keeping Channel.subscribe_to given it was used in docs
 2025-05-24 20:35:37 -07:00
Nuno Campos 0f8f5444bc Lint 2025-05-24 14:54:57 -07:00
Nuno Campos bc17c3522b Remove old checkpoint test fixtures 
- Now all tests fully migrated to more recent sync_checkpointer and async_checkpointer fixtures for parametrising on checkpointer
- Use sync/async_store fixtures where tests used only in memory store
- Remove unused "should snapshot" check for older versions of langchain core no longer tested against
 2025-05-24 14:27:13 -07:00
Nuno Campos 8c11c1155a Remove postgres shallow checkpointer 
- This was deprecated, and superseded by checkpoint_during=False, which is available for all checkpointers
 2025-05-24 12:39:50 -07:00
Nuno Campos 9c79d887a0 Remove ChannelsManager, ManagedValues are now static classes and never instantiated 
- This keeps the existing API for accessing IsLastValue, RemainingSteps, but simplifies the internal implementation
- This lets us remove ChannelsManager completely, which no longer needs to be a context manager, now replaced w function channels_from_checkpoint
- Managed values are now simple functions that return a value given a PregelScratchpad, which will be easier to implement in distributed runner
 2025-05-24 12:15:11 -07:00
Nuno Campos 889b40e7a8 Remove Context channel / managed value, Remove SharedValue 
- Both have been deprecated long ago, have not been present in docs for quite a while
- Removing these lets us delete some code paths that were dedicated to this, easing work on distributed runner
