Follow these guidelines for +development, testing, and security. ## Testing -- Run `cargo test` before every commit to prevent regressions -- Pre-commit hook automatically runs full test suite -- Rate limiting integration test uses separate port for isolation -- All tests must pass before commits are allowed -- Test suite includes: unit tests, config validation, rate limiting under load +- Use unit tests for individual components and integration tests for + end-to-end features. +- Test at appropriate levels to ensure reliability. -## Async Patterns -- Use `.await` on async calls -- Prefer `tokio::fs` over `std::fs` in async contexts -- Handle timeouts for network operations -- Use `Arc` for shared data across tasks +## Development Practices +- Do not remove features unless explicitly ordered, especially those + mentioned in README.md. +- Pre-commit hooks run all tests before commits. +- Follow modern Rust best practices. +- Fix all compiler warnings before committing—they often indicate future bugs. -## Gemini Protocol Specific -- Response format: "STATUS META\r\n" -- Status 20: Success (follow with MIME type) -- Status 41: Server unavailable (timeout, overload) -- Status 51: Not found (resource doesn't exist) -- Status 59: Bad request (malformed URL, protocol violation) -- Default MIME: "text/gemini" for .gmi files -- Default file: "index.gmi" for directory requests +## Security +- Cybersecurity is critical. Never remove guards for remote user input + validation, such as URLs or file paths. -## Error Handling -- **Concurrent request limit exceeded**: Return status 41 "Server unavailable" -- **Timeout**: Return status 41 "Server unavailable" (not 59) -- **Request too large**: Return status 59 "Bad request" -- **Empty request**: Return status 59 "Bad request" -- **Invalid URL format**: Return status 59 "Bad request" -- **Hostname mismatch**: Return status 59 "Bad request" -- **Path resolution failure**: Return status 51 "Not found" (including security violations) -- **File not found**: Return status 51 "Not found" -- Reject requests > 1024 bytes (per Gemini spec) -- Reject requests without proper `\r\n` termination -- Use `tokio::time::timeout()` for request timeout handling -- Configurable concurrent request limit: `max_concurrent_requests` (default: 1000) +## Planning and Tracking +- Use local BACKLOG.md to see planned work. +- For multi-phase changes, add TODO items below the user story with checkboxes + and update them during implementation. -## Configuration -- TOML config files with `serde::Deserialize` -- CLI args override config file values -- Required fields: root, cert, key, host -- Optional: port, log_level, max_concurrent_requests +## Tools +- Use cargo for building and testing. +- Run clippy for code quality checks. +- Use fmt for code formatting. +- Use --quiet flag to suppress startup output during testing. +- Follow project-specific tool usage as needed. -# Development Notes -- Generate self-signed certificates for local testing in `tmp/` directory -- Use CN=localhost for development -- Fix every compiler warning before committing any code -- Create temporary files in the tmp/ directory for your tests like .gem files - or images, etc., so they are gitignored -- Use `path-security` crate for path validation -- Default port: 1965 (standard Gemini port) -- Default host: 0.0.0.0 for listening -- Log level defaults to "info" - -## Environment Setup -- Install clippy: `rustup component add clippy` -- Ensure `~/.cargo/bin` is in PATH (add `source "$HOME/.cargo/env"` to `~/.bashrc`) -- Verify setup: `cargo clippy --version` +## Logging +- Use tracing for logging in nginx/apache style. +- Output goes to stderr for journald/systemd handling. +- No custom log files or eprintln. diff --git a/src/main.rs b/src/main.rs index 90b26bd..6bfbe3b 100644 --- a/src/main.rs +++ b/src/main.rs @@ -33,7 +33,11 @@ fn create_tls_config( fn print_startup_info( config: &config::Config, hosts: &std::collections::HashMap, + quiet: bool, ) { + if quiet { + return;
