CRUST - Change Log

[0.31.0]

  • Update to dual license (MIT/BSD)
  • Upgrade unwrap version to 1.2.0
  • Use rust 1.28.0 stable / 2018-07-07 nightly
  • rustfmt 0.99.2 and clippy-0.0.212

[0.30.1]

  • crate updated to reflect licence changes from GPL to MIT/BSD

[0.30.0]

  • Use rust 1.22.1 stable / 2017-11-23 nightly
  • rustfmt 0.9.0 and clippy-0.0.174

[0.29.0]

  • Replace get_if_addrs module with crate of the same name and fix build issues on mobile platforms.

[0.28.1]

  • Call shutdown() on sockets before dropping them because this fixes a bug under windows.

[0.28.0]

  • Use rust 1.19 stable / 2017-07-20 nightly
  • rustfmt 0.9.0 and clippy-0.0.144
  • Replace -Zno-trans with cargo check
  • Make appveyor script using fixed version of stable
  • Add dev config option
  • Avoid dropping unexpired messages unnecessarily

[0.27.0]

  • Crust handles the whitelist completely by itself instead of delegating it to the upper layers.
  • Config file expanded to cover the cases for node and client whitelists separately.

[0.26.0]

  • Deny bootstrapping off us until explicitly allowed.

[0.25.0]

  • Crust is now templatised on a Uid
  • Replace rust_sodium sha256 with tiny-keccak sha3_256
  • Rustfmt 0.8.3 and clippy 0.0.128.
  • Rust stable 1.17

[0.24.0]

  • Update to mio-v0.6.6
  • Switch from rustc-serialize to serde
  • Remove module containing custom SocketAddr and IpAddr and use std::net equivalents with serde

[0.23.0]

  • Indicate to the crust user if the remote crust trying to bootstrap off us presents itself as a CrustUser::Client (in which case external reacheability check will be subverted) or a CrustUser::Node (in which case external reacheability check will be mandated).

[0.22.1]

  • Add tests for checking the handling of connection to ourselves.
  • Do not spam log Listener wouldblocks.
  • CI, README, Contributor Agreement and clippy clean up.
  • rustfmt 0.8.0 refactor.
  • Fix timer overflow bug.
  • Allow users to force include TCP acceptor port in connection info via new option in crust config file.
  • Debug, Info, Warn and Error levels are reserved strictly for error logging. Trace to log logic flows, specific code-path hits etc.
  • Fix mio to 0.6.4 as 0.6.5 has deprecations and hence breaking changes for us (we treat deprecation warnings as errors currently).

[0.22.0]

  • Port to the new paradigm of mio-v6.
  • Crust can now do echo/stun service on Windows too.
  • Re-enable tests which were ignored on Windows due to prior mio bugs.

[0.21.0]

  • Allow routing to indicate whether we want to bootstrap as a node or as a client. If bootstrapping as a node, message to the bootstrapee will be sent indicating so and bootstrapee will check if we are reacheable externally. Only if this condition is satisfied will we be allowed to successfully bootstrap else it will trigger an immediate BootstrapFailed event.

[0.20.2]

  • Disable hole punching to limit concurrent socket usage.

[0.20.1]

  • Expose functionality to check if the connected peer is one of the hard-coded contacts from the config.

[0.20.0]

  • Expose Config structure.
  • Update rustfmt options.
  • Update documentation links.
  • Add crust_peer example.

[0.19.0]

  • Update to maidsafe_utilities v0.10.0 and adapt to its removal of deprecated API's.

[0.18.0]

  • Provide an API to find out if the connected peer has a whitelisted IP as mentioned in config file.
  • This will currently not work properly on Windows due to (mio-bug)[tokio-rs/mio#397].

[0.17.0]

  • Use rust_sodium instead of sodiumoxide crate.
  • Use latest config_file_handler (0.4.0) to derive the file paths for config and bootstrap cache on various platforms.
  • Use latest maidsafe_utilities (0.9.0).

[0.16.2]

  • Shuffle the bootstrap list, otherwise there is a higher probability of connecting to the ones at the beginning of the list even with parallel bootstrap.
  • Update dependencies to their latest.

[0.16.1]

  • Fix sodiumoxide to v0.0.10 as the new released v0.0.12 does not support rustc-serializable types anymore and breaks builds

[0.16.0]

  • Do not drop messages with Priority value below 2
  • Pull in socket_addr and get_if_addrs crate
  • Refactor to have hole punch and direct connects take the same code route - update NAT Traversal logic
  • Refactor timeout type so that we dont need the indirect mapping of token <-> context and context <-> state
  • Bug fixes
  • Alphabetize imports and use rustfmt.toml which is committed
  • Add temporary function for routing to determine if there are other instances of Crust running on LAN and take actions based on it

[0.15.0]

  • Integrate with mio
    • This currently uses a temporary mio fork (tmp_mio) with windows bug fix.
    • Redesign with State Pattern.
  • Bring number of persistent threads in crust to 1.
    • Previously we would have multiple threads per connection leading to huge number of context switches which was inefficient. It was not uncommon to see more than 200 threads for a little over 60 connections (Routing Table size > 60).
    • Now in many of our tests where cpu would constantly hover around 100%, we have cpu now calm at around 1-5% and peaks to 30% temporarily only during peak stress (Lot of churn and data exchange).
  • Make all system calls async.
    • Switch from application level concurrency primitives to operating system level concurrency.
    • Now with event based mechanism, when kernel is not ready for some state we steal that opportunity to have it service some other state it is ready for which keeps the event pipeline hot and optimal.
  • Attempt bootstrapping in parallel.
    • This increases the speed of bootstrap process. Previously the sequential bootstrap meant we went to next potential peer only if the currently attempted one failed.
  • Remove some of the 1st party dependant crates and move it in as modules.
  • Cleaned out crust config file removing deprecated options.
  • Integrate stun service into connection listeners instead of having them as separate peers.
  • Crust API updates to rename OurConnectionInfo, TheirConnectionInfo to PrivConnectionInfo and PubConnectionInfo.
  • Support bootstrap blacklist.

[0.14.0]

  • Depend on maidsafe_utilities 0.6.0.
  • Fix endianness issue.

[0.13.2]

  • Tweak the algorithm for dropping messages when the bandwitdh is insufficient.

[0.13.1]

  • Ensure dropped duplicate connections dont have messages in transit

[0.13.0]

  • Add message priority to send high-priority messages first and if bandwidth is insufficient, drop the low-priority ones.
  • Add the network_name option to prevent unwanted connections and facilitate starting separate test networks.
  • Avoid duplicate connections to the same peer.

[0.12.0]

  • Remove uTP support.
  • Implement heartbeat messages to detect lost connections more quickly.
  • Add a version number to the protocol to avoid connecting to incompatible peers.
  • Re-implement TCP send/receive using payload size + data.

[0.11.1]

  • Make deserialisation errors as debug instead of error.

[0.11.0]

  • Minor cleanup.
  • Removed unneeded dependency.
  • Tests fixed.

[0.10.0]

  • Peer connections wait for both sides before sending NewPeer events.
  • Enable uTP (still buggy).
  • Add TCP rendezvous.
  • Support port forwarding with ports specified as TCP acceptors.
  • Never raise NewPeer and LostPeer events for ourselves.
  • Update config file format to include service discovery port bootstrap cache name.
  • Fix duplicate NewPeer events.
  • Fix issues 619, 606, 605, 601, 589 and 595.

[0.6.1]

  • Replaced Event with EventSender from maidsafe_utilities

[0.6.0]

  • Don't start any acceptor implicitly.
  • Remove default acceptors settings from config file.
  • Use memory mapped file abstractions to manage bootstrap cache files. We no longer rely on a "file cache owner" that is chosen based on whoever is successful to start some default acceptor implicitly.

  • A new benchmark.
