In the code where changes bloom,
Validate the backend's room.
Flux or Slurm, choose with care,
New checks ensure it's fair.
Tests aligned, functions neat,
CodeRabbit’s job is now complete. 🐇

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Additional comments not posted (5)

tests/test_shared_input_check.py (2)

13-13: Import of validate_backend is correct and aligns with the changes in the function's name and usage.

---

40-42: The test case update for validate_backend correctly reflects the changes in the function's signature and parameters.

pympipool/shared/inputcheck.py (1)

70-85: The implementation of validate_backend correctly handles the new parameters flux_installed and slurm_installed. The function now supports more explicit backend validation based on the installation status of Flux and SLURM.

pympipool/scheduler/__init__.py (2)

16-16: Import of validate_backend and validate_number_of_cores is correct and necessary for the updated create_executor function.

---

90-92: The update in create_executor to use validate_backend with the new parameters flux_installed and slurm_installed is correctly implemented. This change ensures that the backend is validated more robustly based on the system's configuration.
