Leonid Ganeline	8609afbd10	core[patch]: Update `messages` namespace to fix API reference docs (#19161 ) Classes and functions defined in __init__.py are not parsed into the API Reference. For example: - libs/core/langchain_core/messages/__init__.py : AnyMessage, MessageLikeRepresentation, get_buffer_string(), messages_from_dict(), ... Opinionated: __init__.py is not a typical place to define artifacts. Moved artifacts from __init__ into utils.py. Added `MessageLikeRepresentation` to __all__ since it is used outside of `messages`, for example, in `libs/core/langchain_core/language_models/base.py` Added `_message_from_dict` to __all__ since it is used outside of `messages`(???)

Christophe Bornet	4c2e887276	core: Simplify astream logic in BaseChatModel and BaseLLM (#19332 ) Covered by tests in `libs/core/tests/unit_tests/language_models/chat_models/test_base.py`, `libs/core/tests/unit_tests/language_models/llms/test_base.py` and `libs/core/tests/unit_tests/runnables/test_runnable_events.py`	2 months ago
Chris Papademetrious	305d74c67a	core: implement a batch_size parameter for CacheBackedEmbeddings (#18070 ) Description: Currently, `CacheBackedEmbeddings` computes vectors for all uncached documents before updating the store. This pull request updates the embedding computation loop to compute embeddings in batches, updating the store after each batch. I noticed this when I tried `CacheBackedEmbeddings` on our 30k document set and the cache directory hadn't appeared on disk after 30 minutes. The motivation is to minimize compute/data loss when problems occur: * If there is a transient embedding failure (e.g. a network outage at the embedding endpoint triggers an exception), at least the completed vectors are written to the store instead of being discarded. * If there is an issue with the store (e.g. no write permissions), the condition is detected early without computing (and discarding!) all the vectors. Issue: Implements enhancement #18026. Testing: I was unable to run unit tests; details in [this post](https://github.com/langchain-ai/langchain/discussions/15019#discussioncomment-8576684). --------- Signed-off-by: chrispy <chrispy@synopsys.com> Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com>	2 months ago

Roshan Santhosh	7afecec280	core: update _rm_titles to account for title argument name bug (#19036 ) Issue : For functions which have an argument with the name 'title', the convert_pydantic_to_openai_function generates an incorrect output and omits the argument all together. This is because the _rm_titles function removes all instances of the the key 'title' from the output. Description : Updates the _rm_titles function to check the presence of the 'type' key as well before removing the 'title' key. As the title key that we wish to omit always has a type key along with it. Potential gap if there is a function defined which has both title and key as argument names, in which case this would fail. Maybe we could set a filter on the function argument names and reject those with keyword argument names. No dependencies.

William FH	780337488e	[Enhancement] Add support for directly providing a run_id (#18990 ) The root run id (~trace id's) is useful for assigning feedback, but the current recommended approach is to use callbacks to retrieve it, which has some drawbacks: 1. Doesn't work for streaming until after the first event 2. Doesn't let you call other endpoints with the same trace ID in parallel (since you have to wait until the call is completed/started to use This PR lets you provide = "run_id" in the runnable config. Couple considerations: 1. For batch calls, we split the trace up into separate trees (to permit better rendering). We keep the provided run ID for the first one and generate a unique one for other elements of the batch. 2. For nested calls, the provided ID is ONLY used on the top root/trace. ### Example Usage ``` chain.invoke("foo", {"run_id": uuid.uuid4()}) ```	2 months ago

Eugene Yurtsev	93472ee9e6	core[patch]: Replace memory stream implementation used by LogStreamCallbackHandler (#17185 ) This PR replaces the memory stream implementation used by the LogStreamCallbackHandler. This implementation resolves an issue in which streamed logs and streamed events originating from sync code would arrive only after the entire sync code would finish execution (rather than arriving in real time as they're generated). One example is if trying to stream tokens from an llm within a tool. If the tool was an async tool, but the llm was invoked via stream (sync variant) rather than astream (async variant), then the tokens would fail to stream in real time and would all arrived bunched up after the tool invocation completed.	4 months ago
