Ensure that a process-level crypto provider exists

[paulgb]

rustls requires a process-level CryptoProvider be setup. We already do this in dynamic-proxy, which is why those tests pass, but we do not do it in Plane itself so it sometimes fails.

📝 Walkthrough

Walkthrough

This pull request introduces a new dependency to the Cargo.toml file for the plane package, specifically adding the rustls crate at version "0.23.14". This addition expands the project's dependency set, likely enabling enhanced security features related to TLS (Transport Layer Security) through the Rustls library. Additionally, a modification is made in the main function of the plane/src/main.rs file, where a new line is added to call rustls::crypto::ring::default_provider().install_default();. This line is executed after initializing tracing and before invoking the run function with parsed options, indicating a change in the cryptographic provider setup to ensure the default provider from the rustls library is installed. No other modifications to existing dependencies or package metadata are present, nor are there any changes to the logic or control flow in the source code.

  • 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.

36-36: LGTM! Consider using a caret version requirement.

The addition of the rustls dependency is appropriate and aligns with the PR objectives to establish a process-level CryptoProvider. This change is consistent with the project's use of other security-related crates.

Consider using a caret (^) version requirement for more flexible dependency management:

-rustls = "0.23.14"
+rustls = "^0.23.14"

This allows for compatible updates within the 0.23.x range, potentially including bug fixes and minor improvements.

89-90: Approve the crypto provider installation with suggestions for improvement

The addition of rustls::crypto::ring::default_provider().install_default(); addresses the PR objective of establishing a process-level CryptoProvider. This should resolve the issue with certificate loading timing and allow tests to pass.

However, there are a couple of points to consider:

1. Error handling: The result of the installation is currently ignored. Consider adding error handling to catch and log any potential issues during the installation process.

2. Logging: It might be beneficial to add a log statement indicating that the crypto provider has been successfully installed.

Here's a suggested improvement:

match rustls::crypto::ring::default_provider().install_default() {
    Ok(_) => tracing::info!("Default crypto provider installed successfully"),
    Err(e) => tracing::error!("Failed to install default crypto provider: {}", e),
}

To verify the impact of this change, please run the following script:

This script will run the test suite and check for any panics or errors related to the crypto provider in the logs. Please review the results to ensure that the tests are passing and there are no unhandled errors.
