Nuno Campos	ceb73ad06f	core: In BaseRetriever make get_relevant_docs delegate to invoke (#22434 ) - This fixes all the tracing issues with people still using get_relevant_docs, and a change we need for 0.3 anyway Thank you for contributing to LangChain! - [ ] PR title: "package: description" - Where "package" is whichever of langchain, community, core, experimental, etc. is being modified. Use "docs: ..." for purely docs changes, "templates: ..." for template changes, "infra: ..." for CI changes. - Example: "community: add foobar LLM" - [ ] PR message: *Delete this entire checklist* and replace with - Description: a description of the change - Issue: the issue # it fixes, if applicable - Dependencies: any dependencies required for this change - Twitter handle: if your PR gets announced, and you'd like a mention, we'll gladly shout you out! - [ ] Add tests and docs: If you're adding a new integration, please include 1. a test for the integration, preferably unit tests that do not rely on network access, 2. an example notebook showing its use. It lives in `docs/docs/integrations` directory. - [ ] Lint and test: Run `make format`, `make lint` and `make test` from the root of the package(s) you've modified. See contribution guidelines for more: https://python.langchain.com/docs/contributing/ Additional guidelines: - Make sure optional dependencies are imported within a function. - Please do not add dependencies to pyproject.toml files (even optional ones) unless they are required for unit tests. - Most PRs should not touch more than one package. - Changes should be backwards compatible. - If you are adding something to community, do not re-import it in langchain.

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()}) ```	6 months ago
Leonid Ganeline	2f2b77602e	docs: modules descriptions (#17844 ) Several `core` modules do not have descriptions, like the [agent](https://api.python.langchain.com/en/latest/core_api_reference.html#module-langchain_core.agents) module. - Added missed module descriptions. The descriptions are mostly copied from the `langchain` or `community` package modules.	7 months ago
