Pull Request Overview

This PR fixes an issue where only one listener was being selected for a direct connector and introduces refactored connection task handling. Key changes include:

• Adding debug logging for connection attempts.
• Splitting the original connection function into spawn_direct_connect_task and an updated do_try_direct_connect_internal.
• Sorting available listeners to prioritize the default protocol and UDP.

Consider handling the socket address parsing error more explicitly. Returning a Result instead of silently logging and returning might improve error propagation and overall error handling clarity.

Suggested change

	) {
	let Ok(mut addrs) = listener.socket_addrs(|| None) else {
	tracing::error!(?listener, "failed to parse socket address from listener");
	return;
	};
	) -> Result<(), Error> {
	let mut addrs = listener
	.socket_addrs(|| None)
	.map_err(|e| {
	tracing::error!(?listener, ?e, "failed to parse socket address from listener");
	Error::InvalidSocketAddress
	})?;

Add a documentation comment for spawn_direct_connect_task to clarify its intended role in spawning tasks and handling connection attempts, which will aid future maintenance.

Pull Request Overview

This PR fixes an issue where the direct connector only selects one listener by refining the connection retry logic and updating the listener selection flow. Key changes include extending the backoff intervals, refactoring task spawning and listener selection into dedicated functions with improved logging, and removing an unused dependency from Cargo.toml.

• Ensure that your code now imports and uses the intended JoinSet type (e.g., from tokio) to avoid any unresolved import issues after removing the bounded_join_set dependency.

-bounded_join_set = "0.3.0"

For consistency with other structured logging calls in the file, consider using the structured logging syntax (e.g., tracing::debug!(?listener, ...)) instead of relying on string formatting.

Suggested change

	tracing::debug!("try direct connect to peer with listener: {}", listener);
	tracing::debug!(?listener, "try direct connect to peer with listener");
