aquatic/CHANGELOG.md

Changelog

Unreleased

General

Added

• Add aquatic_peer_id crate with peer client information logic

aquatic_udp

Added

• Add support for reporting peer client information

Changed

• Remove support for unbounded worker channels
• Add backpressure in socket workers. They will postpone reading from the socket if sending a request to a swarm worker failed
• Reuse allocations in swarm response channel
• Remove config key network.poll_event_capacity
• Harden ConnectionValidator to make IP spoofing even more costly

aquatic_http

Added

• Reload TLS certificate (and key) on SIGUSR1

Changed

• Allow running without TLS
• Allow running behind reverse proxy

Fixed

• Fix bug where clean up after closing connections wasn't always done

aquatic_ws

Added

• Add support for reporting peer client information
• Reload TLS certificate (and key) on SIGUSR1
• Keep track of which offers peers have sent and only allow matching answers

Changed

• A response is no longer generated when peers announce with AnnounceEvent::Stopped
• Compiling with SIMD extensions enabled is no longer required, due to the addition of runtime detection to simd-json
• Only consider announce and scrape responses as signs of connection still being alive. Previously, all messages sent to peer were considered.
• Decrease default max_peer_age and max_connection_idle config values

Fixed

• Fix bug where clean up after closing connections wasn't always done
• Fix double counting of error responses
• Actually close connections that are too slow to send responses to
• If peers announce with AnnounceEvent::Stopped, allow them to later announce on same torrent with different peer_id

0.8.0 - 2023-03-17

General

Added

• Support exposing a Prometheus endpoint for metrics
• Add cli flag for printing parsed config
• Add aquatic_http_private, an experiment for integrating with private trackers

Changed

• Rename request workers to swarm workers
• Switch to thin LTO for faster compile times
• Use proper workspace path declarations instead of workspace patch section
• Use Rust 1.64 workspace inheritance
• Reduce space taken by ValidUntil struct from 128 to 32 bits, reducing memory consumption for each stored peer by same amount
• Use regular indexmap instead of amortized-indexmap. This goes for torrent, peer and pending scrape response maps
• Improve privilege dropping
• Quit whole program if any thread panics
• Update dependencies

Fixed

• Forbid unrecognized keys when parsing config files
• Stop including invalid avx512 key in ./scripts/env-native-cpu-without-avx-512

aquatic_udp

Added

• Add experimental io_uring backend with higher throughput
• Add optional response resend buffer for use on on operating systems that don't buffer outgoing UDP traffic
• Add optional extended statistics (peers per torrent histogram)
• Add Dockerfile to make it easier to get started

Changed

• Replace ConnectionMap with BLAKE3-based connection validator, greatly decreasing memory consumtion
• Don't return any response peers if announce event is stopped
• Ignore requests with source port value of zero

Fixed

• When calculating bandwidth statistics, include size of protocol headers

aquatic_http

Changed

• Don't return any response peers if announce event is stopped

aquatic_http_protocol

Fixed

• Explicity check for /scrape path
• Return NeedMoreData until headers are fully parsed
• Fix issues with ScrapeRequest::write and AnnounceRequest::write
• Expose write and parse methods for subtypes

aquatic_http_load_test

Changed

• Exclusively use TLS 1.3

aquatic_ws

Added

• Add HTTP health check route when running without TLS

Changed

• Make TLS optional
• Support reverse proxies
• Reduce size of various structs

Fixed

• Remove peer from swarms immediately when connection is closed
• Allow peers to use multiple peer IDs, as long as they only use one per info hash

aquatic_ws_load_test

Changed

• Exclusively use TLS 1.3
