Vwake04	0deb98ac0c	pinecone: Fix multiprocessing issue in PineconeVectorStore (#22571 ) Description: Currently, the `langchain_pinecone` library forces the `async_req` (asynchronous required) argument to Pinecone to `True`. This design choice causes problems when deploying to environments that do not support multiprocessing, such as AWS Lambda. In such environments, this restriction can prevent users from successfully using `langchain_pinecone`. This PR introduces a change that allows users to specify whether they want to use asynchronous requests by passing the `async_req` parameter through `kwargs`. By doing so, users can set `async_req=False` to utilize synchronous processing, making the library compatible with AWS Lambda and other environments that do not support multithreading. Issue: This PR does not address a specific issue number but aims to resolve compatibility issues with AWS Lambda by allowing synchronous processing. Dependencies:** None, that I'm aware of. --------- Co-authored-by: Erick Friis <erick@langchain.dev>	4 weeks ago

mackong	360a70c8a8	core[patch]: fix no current event loop for sql history in async mode (#22933 ) - Description: When use RunnableWithMessageHistory/SQLChatMessageHistory in async mode, we'll get the following error: ``` Error in RootListenersTracer.on_chain_end callback: RuntimeError("There is no current event loop in thread 'asyncio_3'.") ``` which throwed by `ddfbca38df/libs/community/langchain_community/chat_message_histories/sql.py (L259)`. and no message history will be add to database. In this patch, a new _aexit_history function which will'be called in async mode is added, and in turn aadd_messages will be called. In this patch, we use `afunc` attribute of a Runnable to check if the end listener should be run in async mode or not. - Issue: #22021, #22022 - Dependencies: N/A	4 weeks ago

Philippe PRADOS	8711c61298	core[minor]: Adds an in-memory implementation of RecordManager (#13200 ) Description: langchain offers three technologies to save data: - [vectorstore](https://python.langchain.com/docs/modules/data_connection/vectorstores/) - [docstore](https://js.langchain.com/docs/api/schema/classes/Docstore) - [record manager](https://python.langchain.com/docs/modules/data_connection/indexing) If you want to combine these technologies in a sample persistence stategy you need a common implementation for each. `DocStore` propose `InMemoryDocstore`. We propose the class `MemoryRecordManager` to complete the system. This is the prelude to another full-request, which needs a consistent combination of persistence components.
