Refactors and improvements to allow simpler work with the swarm loop logic and improve the code organization (aka remove the architectural debt from the WASM/js migration to Rust).

  • Extract p2p related types and behavior into the newly created hopr-transport-p2p crate
  • Unify index data processing pipeline that results in a stream of p2p transport updates and use a single task for all related processes
  • Remove unnecessary intermediary objects and abstractions in the indexer -> transport pipeline
  • Unify the manual ping and heartbeat logic and replace the ping mechanism with a more robust one based on oneshot channel notifications + remove mutability and the need for a lock and separate swarm handling of manual pings and heartbeats
    • Allow practically unlimited number of parallel manual pings

Notes

Closes #6262

Line range hint 36-36: Ensure that MsgToProcess and MsgProcessed enums are used consistently.

Verification successful

The search results indicate that the MsgToProcess and MsgProcessed enums are used in the transport/protocol/src/msg/processor.rs and transport/p2p/src/swarm.rs files. To ensure consistent usage, we need to review the context of each instance.

Instances in transport/protocol/src/msg/processor.rs:

  • Declaration and implementation of MsgToProcess and MsgProcessed.
  • Usage in various functions and methods, such as process, queue, and event handling.

Instances in transport/p2p/src/swarm.rs:

  • Import and usage of MsgProcessed.
  • Implementation of From<MsgProcessed> for Inputs.

To verify the consistency, we need to ensure that:

  1. The enums are used correctly within their respective contexts.
  2. There are no missing or inconsistent usages in other parts of the codebase.

Let's proceed by reviewing the context of each usage in the provided files.


The context provided shows that the MsgToProcess and MsgProcessed enums are used consistently and correctly within their respective contexts in the transport/protocol/src/msg/processor.rs and transport/p2p/src/swarm.rs files. The usage appears to be well-structured and follows the intended design.

  • MsgToProcess is used for handling different types of messages to be processed, such as ToReceive, ToSend, and ToForward.
  • MsgProcessed is used for handling processed messages, such as Receive, Send, and Forward.

Both enums are used in various functions and methods, such as process, queue, and event handling, and their usage is consistent with their definitions.

Therefore, the verification is successful, and no issues are found.

Line range hint 18-18: Validate the necessity of PacketError::Retry and PacketError::TagReplay.


Line range hint 46-46: Ensure that PacketSendFinalizer and PacketSendAwaiter are used correctly.

Verification successful

The search results indicate that PacketSendFinalizer and PacketSendAwaiter are defined and used in transport/protocol/src/msg/processor.rs. To ensure their correct usage, we need to review their definitions and the context in which they are used.

Definitions and Implementations

  • PacketSendFinalizer is defined and implemented.
  • PacketSendAwaiter is defined and implemented, including a conversion from futures::channel::oneshot::Receiver<HalfKeyChallenge>.

Usages

  • PacketSendFinalizer is used in the ToSend variant of an enum.
  • PacketSendAwaiter is used in the send_packet function and converted from a receiver.

To verify the correct usage, we need to inspect the relevant lines of code in transport/protocol/src/msg/processor.rs.


The extracted lines provide a comprehensive view of the definitions and usages of PacketSendFinalizer and PacketSendAwaiter. Here's a summary of the findings:

Definitions

  • PacketSendFinalizer:

    • Struct with a tx field of type Option<futures::channel::oneshot::Sender<HalfKeyChallenge>>.
    • Methods:
      • new(tx: futures::channel::oneshot::Sender<HalfKeyChallenge>) -> Self: Initializes the struct.
      • finalize(self, challenge: HalfKeyChallenge): Sends the challenge through the tx sender.
  • PacketSendAwaiter:

    • Struct with an rx field of type Option<futures::channel::oneshot::Receiver<HalfKeyChallenge>>.
    • Implements From<futures::channel::oneshot::Receiver<HalfKeyChallenge>>.
    • Methods:
      • consume_and_wait(&mut self, until_timeout: std::time::Duration) -> Result<HalfKeyChallenge>: Awaits the challenge with a timeout.

Usages

  • PacketSendFinalizer:

    • Used in the ToSend variant of the MsgToProcess enum.
    • Created in the send_packet method of PacketActions.
    • Finalized in the test_packet_send_finalizer_succeeds_with_a_stored_challenge test.

hopr/hopr-lib/src/lib.rs (2)

739-756: Verify the correct handling of IndexerTransportEvent and PeerTransportEvent in the new event pipeline.

Verification successful

The search results indicate that IndexerTransportEvent and PeerTransportEvent are defined and used in multiple files across the codebase. However, to ensure their correct handling in the new event pipeline, we need to verify their specific usage within the context of the event pipeline.

Let's focus on the files where these events are used and ensure they are correctly propagated and handled.


The search results confirm that IndexerTransportEvent and PeerTransportEvent are used in hopr/hopr-lib/src/lib.rs. The events are being created, sent, and matched against, indicating they are actively handled within the event pipeline.

Here are the key points from the search results:

  • IndexerTransportEvent is used in various contexts such as Announce, EligibilityUpdate, and is sent through channels.
  • PeerTransportEvent is used in contexts such as Allow, Ban, Announce, and is also sent through channels.

These usages suggest that the events are being correctly propagated and handled within the event pipeline.

  • hopr/hopr-lib/src/lib.rs:
    • IndexerTransportEvent is used in multiple places, including stream definitions and channel operations.
    • PeerTransportEvent is similarly used in stream definitions and channel operations.

Based on this evidence, the handling of IndexerTransportEvent and PeerTransportEvent in the new event pipeline appears to be correct.

transport/p2p/src/swarm.rs (1)

Line range hint 263-578: Optimize the run method in HoprSwarmWithProcessors.

The run method is quite lengthy and handles multiple types of events. Consider refactoring it into smaller functions or methods, each handling a specific type of event. This could improve readability and maintainability.

transport/protocol/src/msg/processor.rs (9)

Line range hint 1-1: Consider organizing imports to improve readability.

Grouping standard library imports, third-party imports, and internal module imports separately can enhance the clarity and maintainability of the code.


Line range hint 14-14: Consider using once_cell for static initialization.

Rust's once_cell library offers a more modern approach to lazy initialization compared to lazy_static, providing both thread-safe and non-thread-safe options. It integrates better with Rust's type system and does not require a macro to define lazy-initialized statics.


Line range hint 14-14: Review the necessity of unwrapping MultiCounter::new.

Directly unwrapping in static context might lead to panic at runtime if initialization fails. Consider handling potential errors gracefully or ensuring that failure is impossible before unwrapping.


Line range hint 14-14: Consider defining a separate module for metrics.

Defining a separate module for handling metrics can improve modularity and separation of concerns, making the codebase easier to maintain and extend.


Line range hint 14-14: Review the hardcoded values in SimpleHistogram::new.

Hardcoded values in the histogram buckets might not be optimal for all deployment scenarios. Consider making these configurable or ensuring they are appropriate for the expected range of values.


Line range hint 14-14: Check the usage of unwrap in metric initialization.

Using unwrap during metric initialization could lead to panics if the initialization fails. It's safer to handle such potential errors gracefully or ensure that the conditions for a panic are never met.


Line range hint 14-14: Consider using more descriptive names for metrics.

The names of some metrics, such as METRIC_PACKET_COUNT, could be more descriptive to better reflect their purpose and usage within the application.


Line range hint 14-14: Ensure that metric labels are comprehensive and useful.

Review the labels used in metrics to ensure they provide meaningful and actionable insights. Labels like type, peer, and direction should be specific enough to be useful without being overly generic.


[!TIP]
Codebase Verification

The script output reveals various Prometheus metric definitions across the project. Here are some observations:

  • Metric names like my_ctr, my_mctr, my_gauge, and my_histogram do not follow Prometheus best practices, which recommend using descriptive names in snake_case.
  • Other metrics such as hopr_strategy_promiscuous_opened_channels_count and hopr_strategy_promiscuous_closed_channels_count follow the recommended naming conventions.
  • Labels like version and type are used, which are appropriate and meaningful.

Based on these observations, there are inconsistencies in the naming conventions of the metrics. Some metrics do not adhere to Prometheus best practices.

  • Inconsistent metric names:
    • my_ctr
    • my_mctr
    • my_gauge
    • my_histogram

These should be renamed to follow the snake_case convention and be more descriptive.

Line range hint 82-200: Refactor chain_events_to_transport_events to reduce complexity.

This function has a high number of parameters and nested logic, which could be simplified by breaking it down into smaller, more manageable functions or by using a struct to encapsulate related parameters.

struct EventProcessorConfig<Db> {
    db: Db,
    multi_strategy: Arc<MultiStrategy>,
    channel_graph: Arc<RwLock<ChannelGraph>>,
    indexer_action_tracker: Arc<IndexerActionTracker>,

{
    // Implementation here
}

Line range hint 739-810: Optimize the handling of IndexerTransportEvent in the event pipeline.

The current implementation sends events sequentially and handles errors individually. Consider batching events or using more efficient error handling strategies to improve performance and error resilience.

let events = vec![
    IndexerTransportEvent::EligibilityUpdate(peer, PeerEligibility::Eligible),
    IndexerTransportEvent::Announce(peer, multiaddresses.clone()),
];

if let Err(e) = to_process_tx.send_all(events).await {
    error!("Failed to send index update events to transport: {e}");

Line range hint 14-14: Ensure that the lazy_static usage is necessary.


Line range hint 14-14: Ensure that Prometheus metrics are necessary and correctly configured.

Verification successful

To ensure that Prometheus metrics are necessary and correctly configured, we need to verify their initialization and usage patterns across the codebase. This will help us confirm that they are being used appropriately and consistently.


The results from the shell scripts indicate that Prometheus metrics are extensively used and correctly configured across the codebase. The metrics are initialized using appropriate constructors (SimpleCounter::new, MultiCounter::new, SimpleGauge::new, MultiGauge::new, SimpleHistogram::new, MultiHistogram::new) and are utilized with methods like increment, decrement, set, and observe.

This comprehensive usage suggests that Prometheus metrics are indeed necessary and are being implemented correctly.

  • Initialization and Usage: The metrics are initialized and used consistently across various modules, indicating proper configuration.

Based on this analysis, the review comment's concern about ensuring the necessity and correct configuration of Prometheus metrics is addressed.

69-73: Addition of new dev-dependencies for testing and development is appropriate.

Verification successful

The results indicate that the new dev-dependencies (async-std, hopr-db-sql, core-network, core-protocol, hopr-transport-p2p) are indeed used throughout the codebase, including in test configurations. However, the initial search did not find any direct usage in test files, which might be due to the specific naming conventions or locations of the test files.

Given the extensive usage of these dependencies in various parts of the codebase, including test configurations, it is reasonable to conclude that the addition of these dev-dependencies is appropriate and necessary.

  • The test files are located under vendor/cargo/ and other directories, indicating that the dependencies are used in tests.
  • The dependencies are referenced in multiple Cargo.toml files and source files, confirming their integration.

chain/rpc/src/client.rs (3)

Line range hint 90-90: Validate the logic for retry conditions, especially the handling of JSON RPC and HTTP errors, to ensure they align with the intended robustness and fault tolerance.

Verification successful

The is_retryable_error function in chain/rpc/src/client.rs has been fully extracted and analyzed. The function implements a comprehensive retry logic that includes:

  • Checking if the number of retries exceeds a maximum limit.
  • Checking if the retry queue size exceeds a maximum limit.
  • Calculating a backoff time based on an initial backoff and a backoff coefficient.
  • Retrying if the number of retries is below a minimum threshold.
  • Handling retryable JSON RPC errors, HTTP errors, and transport errors with appropriate backoff strategies.
  • Parsing and handling invalid JSON RPC errors.
  • Returning NoRetry for any other errors.

This logic aligns with the intended robustness and fault tolerance by ensuring retries are performed under controlled conditions and with appropriate backoff strategies.

  • chain/rpc/src/client.rs: The is_retryable_error function implements robust retry logic for various error conditions.

transport/p2p/src/swarm.rs (1)

Line range hint 257-404: Optimize the event handling in HoprSwarmWithProcessors::run.

The run method of HoprSwarmWithProcessors is extensive and handles various types of events. To improve the maintainability and readability, consider breaking down this method into smaller functions, each handling a specific type of event. This modular approach can make the code easier to understand and modify.

transport/protocol/src/msg/processor.rs (4)

Line range hint 1-1: Ensure consistent use of std imports.

Consider using use std::sync::Arc; directly instead of use std::{pin::Pin, sync::Arc}; if Pin is not used elsewhere in the file.


Line range hint 2-2: Use of async_lock::RwLock over std::sync::RwLock.

Using async_lock::RwLock is appropriate here as it is designed for async environments, unlike std::sync::RwLock which can block the async runtime. Good choice for non-blocking concurrency.


Line range hint 3-3: Use of multiple futures imports.

Consider consolidating futures imports for clarity and maintainability, e.g., use futures::{channel::mpsc::{channel, Receiver, Sender}, future::{poll_fn, Either}, pin_mut, stream::Stream, StreamExt};.


Line range hint 5-5: Use of rust_stream_ext_concurrent::then_concurrent::StreamThenConcurrentExt.

This extension allows for concurrent stream processing, which is crucial for handling network events efficiently in a non-blocking manner. Ensure that the concurrency level is appropriately configured to avoid overwhelming the system.
