Fixes #33986. Summary: - Normalize scheme-less `base_url` values (e.g., `ollama:11434`) by defaulting to `http://` when the input resembles `host:port`. - Preserve and merge `Authorization` headers when `userinfo` credentials are present, both for sync and async clients. - Add unit tests covering scheme-less host:port and scheme-less userinfo credentials. Implementation details: - Update `parse_url_with_auth` to accept scheme-less endpoints, producing a cleaned URL with explicit scheme and extracted auth headers. - No changes required in `OllamaLLM`, `ChatOllama`, or `OllamaEmbeddings`—they already consume the cleaned URL and headers. Why: - Previously, scheme-less inputs caused `parse_url_with_auth` to return `(None, None)`, leading Ollama clients to fall back to defaults and ignore the provided `base_url`. Tests: - Extended `libs/partners/ollama/tests/unit_tests/test_auth.py` to cover the new cases. Notes: - Default scheme chosen is `http` to match common Ollama local deployments. Users can still explicitly provide `https://` when appropriate. --------- Co-authored-by: Mason Daugherty <mason@langchain.dev> Co-authored-by: Mason Daugherty <github@mdrxy.com>

This repository is structured as a monorepo, with various packages located in this libs/ directory. Packages to note in this directory include:
core/ # Core primitives and abstractions for langchain
langchain/ # langchain-classic
langchain_v1/ # langchain
partners/ # Certain third-party providers integrations (see below)

(Each package contains its own README.md file with specific details about that package.)
Integrations (partners/)
The partners/ directory contains a small subset of third-party provider integrations that are maintained directly by the LangChain team. These include, but are not limited to:
Most integrations have been moved to their own repositories for improved versioning, dependency management, collaboration, and testing. This includes packages from popular providers such as Google and AWS. Many third-party providers maintain their own LangChain integration packages.
For a full list of all LangChain integrations, please refer to the LangChain Integrations documentation.
