## Description This PR replaces a bare `except:` clause with `except Exception:` in `libs/core/langchain_core/tracers/core.py`. The previous implementation caught `BaseException`, which includes `SystemExit` and `KeyboardInterrupt`. This meant that if a user tried to interrupt the program (Ctrl+C) during a traceback formatting error, the signal would be suppressed, potentially making the process un-killable. This change ensures that standard runtime errors are still caught and logged, but system control signals are allowed to propagate correctly. ## Verification - Verified via code inspection. - This is a standard safety fix for exception handling patterns in Python to avoid suppressing system exit signals.
Packages
Important
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)
standard-tests/ # Standardized tests for integrations
text-splitters/ # Text splitter utilities
(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.
