Walkthrough

This pull request introduces modifications across multiple files in the nodeman package, focusing on certificate signing request (CSR) verification and configuration. The changes primarily involve updating the StepClient and InternalCertificateAuthority classes to support more flexible CSR verification, adding a new ca_server_verify configuration option, and improving logging practices. The modifications enhance the control flow of CSR processing and provide more granular control over certificate authority server verification.

🐰 Certificates dance with grace,
Verification finds its place,
Logs now whisper, clear and bright,
CSRs signed with newfound might!
A rabbit's code, both smart and light 🔐

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>, please review it.
  • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @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.
