Niklas Adolfsson 3216b143c2 ethcore/VerificationQueue don't spawn up extra worker-threads when explictly specified not to (#9620)
* VerificationQueue don't spawn up extra threads

In the verification queue we spawn up worker threads to do the work.
However, if `num-verifiers` is specified we still spawn the maximum
number of threads which consume extra memory.

There is one catch though when `--scale-verifiers` is specified then
we can't do it because all threads are created upon initilization AFAIK.

In my opinion, is doesn't to use both `num-verifiers` and
`scale-verifiers` they are kind of contradictory!

* Fix nits in logic and add tests for verification

* refactor(verification queue) - rm hardcoded const

* Address grumbles in new tests
* Remove hardcoded `MAX_VERIFIERS` constant and replace it by relying
entirely on `num_cpu` crate instead inorder to support CPUs that have
more cores/logical cores

Parity Ethereum

The fastest and most advanced Ethereum client.

» Download the latest release «

Built for mission-critical use: Miners, service providers, and exchanges need fast synchronisation and maximum uptime. Parity Ethereum provides the core infrastructure essential for speedy and reliable services.

  • Clean, modular codebase for easy customisation
  • Advanced CLI-based client
  • Minimal memory and storage footprint
  • Synchronise in hours, not days with Warp Sync
  • Modular for light integration into your service or product

Technical Overview

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

By default, Parity Ethereum runs a JSON-RPC HTTP server on port :8545 and a Web-Sockets server on port :8546. This is fully configurable and supports a number of APIs.

If you run into problems while using Parity Ethereum, check out the wiki for documentation, feel free to file an issue 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 Ethereum's current beta-release is 2.1. You can download it at the releases page or follow the instructions below to build from source. Please, mind the CHANGELOG.md for a list of all changes between different versions.

Build Dependencies

Parity Ethereum requires Rust version 1.29.x 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 Ethereum also requires gcc, g++, libudev-dev, pkg-config, file, make, and cmake 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 Ethereum from source.

Install from the Snapcraft Store

In any of the supported Linux distros:

sudo snap install parity

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

sudo snap install parity --beta

Moreover, to test the latest code from the master branch:

sudo snap install parity --edge

Build from Source Code

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

# build in release mode
$ cargo build --release --features final

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

$ git checkout stable

or

$ git checkout beta

Simple One-Line Installer for Mac and Linux

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 Ethereum

Manually

To start Parity Ethereum manually, just run

$ ./target/release/parity

so Parity Ethereum begins syncing the Ethereum blockchain.

Using systemd service file

To start Parity Ethereum 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 Ethereum, write a /etc/parity/config.toml config file, see Configuring Parity Ethereum for details.

Parity Ethereum toolchain

In addition to the Parity Ethereum client, there are additional tools in this repository available:

  • evmbin - EVM implementation for Parity Ethereum.
  • ethabi - Parity Ethereum function calls encoding.
  • ethstore - Parity Ethereum key management.
  • ethkey - Parity Ethereum keys generator.
  • whisper - Implementation of Whisper-v2 PoC.
