Ensure that APT isn't used

• Ensuring that Advanced Packaging Tool (APT) isn't used helps to prevent security vulnerabilities from unverified packages or outdated versions, improving the overall security posture of the docker container.
• By not using APT, we reduce the risk of an attacker exploiting known bugs present in packages that are included in APT but haven’t been patched yet, thereby enhancing the resilience of the system against potential attacks.

🔒 No security issues identified

⚡ Recommended areas for review Test Coverage The new test test_ruby_decorator_references is added to verify Ruby decorator references. Ensure that this test covers all relevant scenarios and edge cases for Ruby decorator references. Error Handling The RubyClient::new function logs an error when failing to start the ruby-lsp process but does not provide a mechanism to handle this error gracefully. Consider adding error handling to manage this failure scenario. Language Detection The addition of Ruby language support in the detect_language function should be thoroughly tested to ensure it correctly identifies Ruby files under various conditions.

[codeant-ai]

Suggestion: Consider adding error handling for the find_references function call to manage potential failures gracefully. [best practice]

Suggested change

	let response = find_references(state, mock_request).await;
	let response = find_references(state, mock_request).await?;

[codeant-ai]

Suggestion: Consider handling the case where workspace_folders might be empty to avoid potential runtime errors when accessing the first element. [possible issue]

Suggested change

	root_uri: workspace_folders.first().map(|f| f.uri.clone()), // <--------- Not default behavior
	root_uri: workspace_folders.first().map(|f| f.uri.clone()).or_else(|| Some(default_uri)),

[codeant-ai]

Suggestion: Ensure that the Command::new("ruby-lsp") is resilient to the absence of the ruby-lsp executable by providing a more informative error message. [best practice]

Suggested change

	.map_err(|e| {
	eprintln!("Failed to start ruby-lsp process: {}", e);
	Box::new(e) as Box<dyn std::error::Error + Send + Sync>
	})?;
	.map_err(|e| {
	eprintln!("Failed to start ruby-lsp process. Ensure 'ruby-lsp' is installed and accessible: {}", e);
	Box::new(e) as Box<dyn std::error::Error + Send + Sync>
	})?;

[codeant-ai]

Suggestion: Consider adding a check to verify if Ruby is already installed before attempting to install it, to avoid unnecessary installations. [enhancement]

Suggested change

	DEBIAN_FRONTEND=noninteractive apt-get install -y ruby-full
	if ! command -v ruby &> /dev/null; then DEBIAN_FRONTEND=noninteractive apt-get install -y ruby-full; fi

[codeant-ai]

Suggestion: Combine the Ruby installation commands into a single RUN command to reduce the number of layers in the Docker image. [performance]

Suggested change

	RUN apt update && apt install -y ruby-full \
	&& apt-get clean \
	&& rm -rf /var/lib/apt/lists/*
	RUN gem install ruby-lsp
	RUN apt update && apt install -y ruby-full \
	&& gem install ruby-lsp \
	&& apt-get clean \
	&& rm -rf /var/lib/apt/lists/*
