jigsawlabs-student	427a04151c	community: fix neo4j from_existing_graph (#24912 ) Fixes Neo4JVector.from_existing_graph integration with huggingface Previously threw an error with existing databases, because from_existing_graph query returns empty list of new nodes, which are then passed to embedding function, and huggingface errors with empty list.

Eugene Yurtsev	41dfad5104	core[minor]: Introduce DocumentIndex abstraction (#25062 ) This PR adds a minimal document indexer abstraction. The goal of this abstraction is to allow developers to create custom retrievers that also have a standard indexing API and allow updating the document content in them. The abstraction comes with a test suite that can verify that the indexer implements the correct semantics. This is an iteration over a previous PRs (https://github.com/langchain-ai/langchain/pull/24364). The main difference is that we're sub-classing from BaseRetriever in this iteration and as so have consolidated the sync and async interfaces. The main problem with the current design is that runt time search configuration has to be specified at init rather than provided at run time. We will likely resolve this issue in one of the two ways: (1) Define a method (`get_retriever`) that will allow creating a retriever at run time with a specific configuration.. If we do this, we will likely break the subclass on BaseRetriever (2) Generalize base retriever so it can support structured queries --------- Co-authored-by: Erick Friis <erick@langchain.dev>	2 months ago

Stuart Marsh	16bd0697dc	milvus: fixed bug when using partition key and dynamic fields together (#25028 ) Description: This PR fixes a bug where if `enable_dynamic_field` and `partition_key_field` are enabled at the same time, a pymilvus error occurs. Milvus requires the partition key field to be a full schema defined field, and not a dynamic one, so it will throw the error "the specified partition key field {field} not exist" when creating the collection. When `enabled_dynamic_field` is set to `True`, all schema field creation based on `metadatas` is skipped. This code now checks if `partition_key_field` is set, and creates the field. Integration test added. Twitter handle: StuartMarshUK --------- Co-authored-by: Stuart Marsh <stuart.marsh@qumata.com> Co-authored-by: Erick Friis <erick@langchain.dev>	2 months ago
Jim Baldwin	6890daa90c	community: make AthenaLoader profile_name optional and fix type hint (#24958 ) - Description: This PR makes the AthenaLoader profile_name optional and fixes the type hint which says the type is `str` but it should be `str` or `None` as None is handled in the loader init. This is a minor problem but it just confused me when I was using the Athena Loader to why we had to use a Profile, as I want that for local but not production. - Issue: #24957 - Dependencies: None.	2 months ago

WU LIFU	ad16eed119	core[patch]: runnable config ensure_config deep copy from var_child_runnable… (#24862 ) issue: #24660 RunnableWithMessageHistory.stream result in error because the [evaluation](https://github.com/langchain-ai/langchain/blob/master/libs/core/langchain_core/runnables/branch.py#L220) of the branch [condition](`99eb31ec41/libs/core/langchain_core/runnables/history.py (L328C1-L329C1)`) unexpectedly trigger the "[on_end](`99eb31ec41/libs/core/langchain_core/runnables/history.py (L332)`)" (exit_history) callback of the default branch descriptions After a lot of investigation I'm convinced that the root cause is that 1. during the execution of the runnable, the [var_child_runnable_config](`99eb31ec41/libs/core/langchain_core/runnables/config.py (L122)`) is shared between the branch [condition](`99eb31ec41/libs/core/langchain_core/runnables/history.py (L328C1-L329C1)`) runnable and the [default branch runnable](`99eb31ec41/libs/core/langchain_core/runnables/history.py (L332)`) within the same context 2. when the default branch runnable runs, it gets the [var_child_runnable_config](`99eb31ec41/libs/core/langchain_core/runnables/config.py (L163)`) and may unintentionally [add more handlers ](`99eb31ec41/libs/core/langchain_core/runnables/config.py (L325)`)to the callback manager of this config 3. when it is again the turn for the [condition](`99eb31ec41/libs/core/langchain_core/runnables/history.py (L328C1-L329C1)`) to run, it gets the `var_child_runnable_config` whose callback manager has the handlers added by the default branch. When it runs that handler (`exit_history`) it leads to the error with the assumption that, the `ensure_config` function actually does want to create a immutable copy from `var_child_runnable_config` because it starts with an [`empty` variable ](`99eb31ec41/libs/core/langchain_core/runnables/config.py (L156)`), i go ahead to do a deepcopy to ensure that future modification to the returned value won't affect the `var_child_runnable_config` variable Having said that I actually 1. don't know if this is a proper fix 2. don't know whether it will lead to other unintended consequence 3. don't know why only "stream" runs into this issue while "invoke" runs without problem so @nfcampos @hwchase17 please help review, thanks! --------- Co-authored-by: Lifu Wu <lifu@nextbillion.ai> Co-authored-by: Nuno Campos <nuno@langchain.dev> Co-authored-by: Bagatur <baskaryan@gmail.com>	2 months ago
