It is the entry point into the Ethereum network (main-, test- or private net), capable of running as a full node (default), archive node (retaining all historical state) or a light node (retrieving data live). It can be used by other processes as a gateway into the Ethereum network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. `geth --help` and the [CLI Wiki page](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options) for command line options. | -| `abigen` | Source code generator to convert Ethereum contract definitions into easy to use, compile-time type-safe Go packages. It operates on plain [Ethereum contract ABIs](https://github.com/ethereum/wiki/wiki/Ethereum-Contract-ABI) with expanded functionality if the contract bytecode is also available. However it also accepts Solidity source files, making development much more streamlined. Please see our [Native DApps](https://github.com/ethereum/go-ethereum/wiki/Native-DApps:-Go-bindings-to-Ethereum-contracts) wiki page for details. | -| `bootnode` | Stripped down version of our Ethereum client implementation that only takes part in the network node discovery protocol, but does not run any of the higher level application protocols. It can be used as a lightweight bootstrap node to aid in finding peers in private networks. | -| `evm` | Developer utility version of the EVM (Ethereum Virtual Machine) that is capable of running bytecode snippets within a configurable environment and execution mode. Its purpose is to allow isolated, fine-grained debugging of EVM opcodes (e.g. `evm --code 60ff60ff --debug`). | -| `gethrpctest` | Developer utility tool to support our [ethereum/rpc-test](https://github.com/ethereum/rpc-tests) test suite which validates baseline conformity to the [Ethereum JSON RPC](https://github.com/ethereum/wiki/wiki/JSON-RPC) specs.

It is an alternative package to [`gousb`](https://github.com/karalabe/gousb) for use -cases where devices support this ligher mode of operation (e.g. input devices, hardware crypto wallets). - -The package wraps [`hidapi`](https://github.com/signal11/hidapi) for accessing OS specific USB HID APIs -directly instead of using low level USB constructs, which might have permission issues on some platforms. -On Linux the package also wraps [`libusb`](https://github.com/libusb/libusb). Both of these dependencies -are vendored directly into the repository and wrapped using CGO, making the `hid` package self-contained -and go-gettable. - -Supported platforms at the moment are Linux, macOS and Windows (exclude constraints are also specified -for Android and iOS to allow smoother vendoring into cross platform projects). - -## Cross-compiling - -Using `go get` the embedded C library is compiled into the binary format of your host OS. Cross compiling to a different platform or architecture entails disabling CGO by default in Go, causing device enumeration `hid.Enumerate()` to yield no results. - -To cross compile a functional version of this library, you'll need to enable CGO during cross compilation via `CGO_ENABLED=1` and you'll need to install and set a cross compilation enabled C toolkit via `CC=your-cross-gcc`. - -## Acknowledgements - -Although the `hid` package is an implementation from scratch, it was heavily inspired by the existing -[`go.hid`](https://github.com/GeertJohan/go.hid) library, which seems abandoned since 2015; is incompatible -with Go 1.6+; and has various external dependencies. Given its inspirational roots, I thought it important -to give credit to the author of said package too. - -Wide character support in the `hid` package is done via the [`gowchar`](https://github.com/orofarne/gowchar) -library, unmaintained since 2013; non buildable with a modern Go release and failing `go vet` checks.

The goal of the library was to create a simple way to find-, attach to- and read/write form USB devices. + +There are multiple already existing USB libraries: + + * The original `gousb` package [created by @kylelemons](https://github.com/kylelemons/gousb) and nowadays [maintained by @google](https://github.com/google/gousb) is a CGO wrapper around `libusb`. It is the most advanced USB library for Go out there. + * Unfortunately, `gousb` requires the `libusb` C library to be installed both during build as well as during runtime on the host operating system. This breaks binary portability and also adds unnecessary hurdles on Windows. + * Furthermore, whilst HID devices are supported by `libusb`, the OS on Macos and Windows explicitly takes over these devices, so only native system calls can be used on recent versions (i.e. you **cannot** use `libusb` for HID). + * There is a fork of `gousb` [created by @karalabe](https://github.com/karalabe/gousb) that statically linked `libusb` during build, but with the lack of HID access, that work was abandoned. + * For HID-only devices, a previous self-contained package was created at [`github.com/karalabe/hid`](https://github.com/karalabe/hid), which worked well for hardware wallet uses cases in [`go-ethereum`](https://github.com/ethereum/go-ethereum). It's a simple package that does it's thing well. + * Unfortunately, `hid` is not capable of talking to generic USB devices. When multiple different devices are needed, eventually some will not support the HID spec (e.g. WebUSB). Pulling in both `hid` and `gousb` will break down due to both depending internally on different versions of `libusb` on Linux. + +This `usb` package is a proper integration of `hidapi` and `libusb` so that communication with HID devices is done via system calls, whereas communication with lower level USB devices is done via interrupts. All this detail is hidden away behind a tiny interface. + +The package supports Linux, macOS, Windows and FreeBSD. Exclude constraints are also specified for Android and iOS to allow smoother vendoring into cross platform projects. + +## Cross-compiling + +Using `go get`, the embedded C library is compiled into the binary format of your host OS. Cross compiling to a different platform or architecture entails disabling CGO by default in Go, causing device enumeration `hid.Enumerate()` to yield no results. + +To cross compile a functional version of this library, you'll need to enable CGO during cross compilation via `CGO_ENABLED=1` and you'll need to install and set a cross compilation enabled C toolkit via `CC=your-cross-gcc`. + +## Acknowledgements + +Although the `usb` package is an implementation from scratch, HID support was heavily inspired by the existing [`go.hid`](https://github.com/GeertJohan/go.hid) library, which seems abandoned since 2015; is incompatible with Go 1.6+; and has various external dependencies. + +Wide character support in the HID support is done via the [`gowchar`](https://github.com/orofarne/gowchar) library, unmaintained since 2013; non buildable with a modern Go release and failing `go vet` checks. As such, `gowchar` was also vendored in inline. + +Error handling for the `libusb` integration originates from the [`gousb`](https://github.com/google/gousb) library. + +## License + +This USB library is licensed under the [GNU Lesser General Public License v3.0](https://www.gnu.org/licenses/lgpl-3.0.en.html) (dictated by libusb). + +If you are only interested in Human Interface devices, a less restrictive package can be found at [`github.com/karalabe/hid`](https://github.com/karalabe/hid). diff --git a/vendor/github.com/karalabe/hid/appveyor.yml b/vendor/github.com/karalabe/usb/appveyor.yml similarity index 75% rename from vendor/github.com/karalabe/hid/appveyor.yml rename to vendor/github.com/karalabe/usb/appveyor.yml index 84b3c95ff..73a9664ae 100644 --- a/vendor/github.com/karalabe/hid/appveyor.yml +++ b/vendor/github.com/karalabe/usb/appveyor.yml @@ -1,7 +1,7 @@ os: Visual Studio 2015 # Clone directly into GOPATH. -clone_folder: C:\gopath\src\github.com\karalabe\hid +clone_folder: C:\gopath\src\github.com\karalabe\usb clone_depth: 1 version: "{branch}.{build}" environment: @@ -22,11 +22,14 @@ environment: install: - rmdir C:\go /s /q - - appveyor DownloadFile https://storage.googleapis.com/golang/go1.10.1.windows-%GOARCH%.zip - - 7z x go1.10.1.windows-%GOARCH%.zip -y -oC:\ > NUL + - appveyor DownloadFile https://storage.googleapis.com/golang/go1.12.9.windows-%GOARCH%.zip + - 7z x go1.12.9.windows-%GOARCH%.zip -y -oC:\ > NUL - go version - gcc --version build_script: - go install ./... - go test -v ./... + - set CGO_ENABLED=0 + - go install ./... + - go test -v ./... diff --git a/vendor/github.com/karalabe/usb/demo.go b/vendor/github.com/karalabe/usb/demo.go new file mode 100644 index 000000000..229faaf5f --- /dev/null +++ b/vendor/github.com/karalabe/usb/demo.go @@ -0,0 +1,76 @@ +// usb - Self contained USB and HID library for Go +// Copyright 2019 The library Authors +// +// This library is free software: you can redistribute it and/or modify it under +// the terms of the GNU Lesser General Public License as published by the Free +// Software Foundation, either version 3 of the License, or (at your option) any +// later version. +// +// The library is distributed in the hope that it will be useful, but WITHOUT ANY +// WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR +// A PARTICULAR PURPOSE.

The transport upgrader negotiates transport security and +multiplexing for each connection according to the protocols supported by each +party. + +## reuseport + +The [`SO_REUSEPORT`][explain-reuseport] socket option allows multiple processes +or threads to bind to the same TCP port, provided that all of them set the +socket option. This has some performance benefits, and it can potentially assist +in NAT traversal by only requiring one port to be accessible for many +connections. + +The reuseport functionality is provided by a seperate module, +[go-reuseport-transport](https://github.com/libp2p/go-reuseport-transport). It +is enabled by default, but can be disabled at runtime by setting the +`LIBP2P_TCP_REUSEPORT` environment variable to `false` or `0`. + ## Contribute PRs are welcome! @@ -38,3 +136,12 @@ MIT ©
