Jim Posen 01f825b0e1 Multiple improvements to discovery ping handling (#8771)
* discovery: Only add nodes to routing table after receiving pong.

Previously the discovery algorithm would add nodes to the routing table
before confirming that the endpoint is participating in the protocol. This
now tracks in-flight pings and adds to the routing table only after receiving
a response.

* discovery: Refactor packet creation into its own function.

This function is useful inside unit tests.

* discovery: Additional testing for new add_node behavior.

* discovery: Track expiration of pings to non-yet-in-bucket nodes.

Now that we may ping nodes before adding to a k-bucket, the timeout tracking
must be separate from BucketEntry.

* discovery: Verify echo hash on pong packets.

Stores packet hash with in-flight requests and matches with pong response.

* discovery: Track timeouts on FIND_NODE requests.

* discovery: Retry failed pings with exponential backoff.

UDP packets may get dropped, so instead of immediately booting nodes that fail
to respond to a ping, retry 4 times with exponential backoff.

* !fixup Use slice instead of Vec for request_backoff.

About Parity

Parity's goal is to be the fastest, lightest, and most secure Ethereum client. We are developing Parity using the sophisticated and cutting-edge Rust programming language. Parity is licensed under the GPLv3, and can be used for all your Ethereum needs.

From Parity Ethereum client version 1.10.0, the User Interface (UI) is accessible in a separate application called Parity UI. To keep using the UI in the browser (deprecated), follow these steps.

By default, Parity will also run a JSONRPC server on 127.0.0.1:8545 and a websockets server on 127.0.0.1:8546. This is fully configurable and supports a number of APIs.

If you run into an issue while using Parity, feel free to file one in this repository or hop on our Gitter or Riot chat room to ask a question. We are glad to help! For security-critical issues, please refer to the security policy outlined in SECURITY.MD.

Parity's current beta-release is 1.11. You can download it at https://github.com/paritytech/parity/releases or follow the instructions below to build from source.


Build dependencies

Parity requires Rust version 1.26.0 to build

We recommend installing Rust through rustup. If you don't already have rustup, you can install it like this:

  • Linux:

    $ curl https://sh.rustup.rs -sSf | sh
    

    Parity also requires gcc, g++, libssl-dev/openssl, libudev-dev, pkg-config, file and make packages to be installed.

  • OSX:

    $ curl https://sh.rustup.rs -sSf | sh
    

    clang is required. It comes with Xcode command line tools or can be installed with homebrew.

  • Windows Make sure you have Visual Studio 2015 with C++ support installed. Next, download and run the rustup installer from https://static.rust-lang.org/rustup/dist/x86_64-pc-windows-msvc/rustup-init.exe, start "VS2015 x64 Native Tools Command Prompt", and use the following command to install and set up the msvc toolchain:

      $ rustup default stable-x86_64-pc-windows-msvc
    

Once you have rustup installed, then you need to install:

Make sure that these binaries are in your PATH. After that you should be able to build parity from source.


Install from the snap store

In any of the supported Linux distros:

sudo snap install parity

Or, if you want to contribute testing the upcoming release:

sudo snap install parity --beta

And to test the latest code landed into the master branch:

sudo snap install parity --edge

Build from source

# download Parity code
$ git clone https://github.com/paritytech/parity
$ cd parity

# build in release mode
$ cargo build --release

This will produce an executable in the ./target/release subdirectory.

Note: if cargo fails to parse manifest try:

$ ~/.cargo/bin/cargo build --release

Note, when compiling a crate and you receive errors, it's in most cases your outdated version of Rust, or some of your crates have to be recompiled. Cleaning the repository will most likely solve the issue if you are on the latest stable version of Rust, try:

$ cargo clean

This will always compile the latest nightly builds. If you want to build stable or beta, do a

$ git checkout stable

or

$ git checkout beta

first.


Simple one-line installer for Mac and Ubuntu

bash <(curl https://get.parity.io -L)

The one-line installer always defaults to the latest beta release. To install a stable release, run:

bash <(curl https://get.parity.io -L) -r stable

Start Parity

Manually

To start Parity manually, just run

$ ./target/release/parity

and Parity will begin syncing the Ethereum blockchain.

Using systemd service file

To start Parity as a regular user using systemd init:

  1. Copy ./scripts/parity.service to your systemd user directory (usually ~/.config/systemd/user).
  2. To configure Parity, write a /etc/parity/config.toml config file, see Configuring Parity for details.
