fix: serialize configure locator updates (#416)
Summary:
- Apply configure updates and long-lived locator reconfiguration under
the same configuration write lock.
- Keep refresh-state sync from interleaving with shared locator
reconfiguration.
- Add a regression test that blocks locator configuration and verifies
configuration readers cannot observe the new state early.

Validation:
- cargo test -p pet
test_configure_publishes_state_after_shared_locators_are_configured
- cargo test -p pet jsonrpc::tests::test_
- cargo fmt --all
- cargo clippy --all -- -D warnings

Fixes #385

Python environment tools for Visual Studio Code

Performant Python environment tooling and support, such as locating all global Python installs and virtual environments.

This project will be consumed by the Python extension directly. You can find the code to consume pet in the Python extension source code. For more information on JSNORPC requests/notifications for this tool, please reference /docs/JSONRPC.md.

Environment Types Supported

  • python.org
  • Windows Store
  • PyEnv
  • PyEnv-Win
  • PyEnv-Virtualenv
  • Conda
  • Miniconda
  • Miniforge
  • PipEnv
  • Homebrew
  • VirtualEnvWrapper
  • VirtualEnvWrapper-Win
  • Venv
  • VirtualEnv
  • Python on your PATH

Features

  • Discovery of all global Python installs
  • Discovery of all Python virtual environments

Key Methodology

Our approach prioritizes performance and efficiency by leveraging Rust. We minimize I/O operations by collecting all necessary environment information at once, which reduces repeated I/O and the need to spawn additional processes, significantly enhancing overall performance.

Locator refresh-state contracts are documented in docs/LOCATOR_STATE.md.
