William FH	9fa9f05e5d	Catch System Error in ast parse (#20961 ) I can't seem to reproduce, but i got this: ``` SystemError: AST constructor recursion depth mismatch (before=102, after=37) ``` And the operation isn't critical for the actual forward pass so seems preferable to expand our caught exceptions	5 months ago

Eugene Yurtsev	d8aa72f51d	core[minor],langchain[patch]: Move base indexing interface and logic to core (#20667 ) This PR moves the interface and the logic to core. The following changes to namespaces: `indexes` -> `indexing` `indexes._api` -> `indexing.api` Testing code is intentionally duplicated for now since it's testing different implementations of the record manager (in-memory vs. SQL). Common logic will need to be pulled out into the test client. A follow up PR will move the SQL based implementation outside of LangChain.	5 months ago

Eugene Yurtsev	a2cc9b55ba	core[patch]: Remove autoupgrade to addable dict in Runnable/RunnableLambda/RunnablePassthrough transform (#20677 ) Causes an issue for this code ```python from langchain.chat_models.openai import ChatOpenAI from langchain.output_parsers.openai_tools import JsonOutputToolsParser from langchain.schema import SystemMessage prompt = SystemMessage(content="You are a nice assistant.") + "{question}" llm = ChatOpenAI( model_kwargs={ "tools": [ { "type": "function", "function": { "name": "web_search", "description": "Searches the web for the answer to the question.", "parameters": { "type": "object", "properties": { "query": { "type": "string", "description": "The question to search for.", }, }, }, }, } ], }, streaming=True, ) parser = JsonOutputToolsParser(first_tool_only=True) llm_chain = prompt \| llm \| parser \| (lambda x: x) for chunk in llm_chain.stream({"question": "tell me more about turtles"}): print(chunk) # message = llm_chain.invoke({"question": "tell me more about turtles"}) # print(message) ``` Instead by definition, we'll assume that RunnableLambdas consume the entire stream and that if the stream isn't addable then it's the last message of the stream that's in the usable format. --- If users want to use addable dicts, they can wrap the dict in an AddableDict class. --- Likely, need to follow up with the same change for other places in the code that do the upgrade	5 months ago

Leonid Ganeline	45d045b2c5	core[minor], langchain[patch]: `tools` dependencies refactoring (#18759 ) The `langchain.tools` [namespace](https://api.python.langchain.com/en/latest/langchain_api_reference.html#module-langchain.tools) can be completely eliminated by moving one class and 3 functions into `core`.

Alexander Smirnov	ece008f117	docs: Refine RunnablePassthrough docstring (#19812 ) Description: This update refines the documentation for `RunnablePassthrough` by removing an unnecessary import and correcting a minor syntactical error in the example provided. This change enhances the clarity and correctness of the documentation, ensuring that users have a more accurate guide to follow. Issue: N/A Dependencies: None This PR focuses solely on documentation improvements, specifically targeting the `RunnablePassthrough` class within the `langchain_core` module. By clarifying the example provided in the docstring, users are offered a more straightforward and error-free guide to utilizing the `RunnablePassthrough` class effectively. As this is a documentation update, it does not include changes that require new integrations, tests, or modifications to dependencies. It adheres to the guidelines of minimal package interference and backward compatibility, ensuring that the overall integrity and functionality of the LangChain package remain unaffected. Thank you for considering this documentation refinement for inclusion in the LangChain project.	5 months ago
