This commit adds a new package (rpctest) which provides functionality for writing automated black box tests to exercise the RPC interface. An instance of a rpctest consists of an active btcd process running in (typically) --simnet mode, a btcrpcclient instance connected to said node, and finally an embedded in-memory wallet instance (the memWallet) which manages any created coinbase outputs created by the mining btcd node. As part of the SetUp process for an RPC test, a test author can optionally opt to have a test blockchain created. The second argument to SetUp dictates the number of mature coinbase outputs desired. The btcd process will then be directed to generate a test chain of length: 100 + numMatureOutputs. The embedded memWallet instance acts as a minimal, simple wallet for each Harness instance. The memWallet itself is a BIP 32 HD wallet capable of creating new addresses, creating fully signed transactions, creating+broadcasting a transaction paying to an arbitrary set of outputs, and querying the currently confirmed balance. In order to test various scenarios of blocks containing arbitrary transactions, one can use the Generate rpc call via the exposed btcrpcclient connected to the active btcd node. Additionally, the Harness also exposes a secondary block generation API allowing callers to create blocks with a set of hand-selected transactions, and an arbitrary BlockVersion or Timestamp. After execution of test logic TearDown should be called, allowing the test instance to clean up created temporary directories, and shut down the running processes. Running multiple concurrent rpctest.Harness instances is supported in order to allow for test authors to exercise complex scenarios. As a result, the primary interface to create, and initialize an rpctest.Harness instance is concurrent safe, with shared package level private global variables protected by a sync.Mutex. Fixes #116. |

btcd
[

(https://travis-ci.org/btcsuite/btcd)
btcd is an alternative full node bitcoin implementation written in Go (golang).
This project is currently under active development and is in a Beta state. It is extremely stable and has been in production use since October 2013.
It properly downloads, validates, and serves the block chain using the exact rules (including bugs) for block acceptance as Bitcoin Core. We have taken great care to avoid btcd causing a fork to the block chain. It passes all of the 'official' block acceptance tests (https://github.com/TheBlueMatt/test-scripts) as well as all of the JSON test data in the Bitcoin Core code.
It also relays newly mined blocks, maintains a transaction pool, and relays individual transactions that have not yet made it into a block. It ensures all transactions admitted to the pool follow the rules required by the block chain and also includes the same checks which filter transactions based on miner requirements ("standard" transactions) as Bitcoin Core.
One key difference between btcd and Bitcoin Core is that btcd does NOT include wallet functionality and this was a very intentional design decision. See the blog entry here for more details. This means you can't actually make or receive payments directly with btcd. That functionality is provided by the btcwallet and Paymetheus (Windows-only) projects which are both under active development.
Requirements
Go 1.6 or newer.
Installation
Windows - MSI Available
https://github.com/btcsuite/btcd/releases
Linux/BSD/MacOSX/POSIX - Build from Source
-
Install Go according to the installation instructions here: http://golang.org/doc/install
-
Ensure Go was installed properly and is a supported version:
$ go version
$ go env GOROOT GOPATH
NOTE: The GOROOT and GOPATH above must not be the same path. It is
recommended that GOPATH is set to a directory in your home directory such as
~/goprojects to avoid write permission issues. It is also recommended to add
$GOPATH/bin to your PATH at this point.
- Run the following commands to obtain btcd, all dependencies, and install it:
$ go get -u github.com/Masterminds/glide
$ git clone https://github.com/btcsuite/btcd $GOPATH/src/github.com/btcsuite/btcd
$ cd $GOPATH/src/github.com/btcsuite/btcd
$ glide install
$ go install . ./cmd/...
- btcd (and utilities) will now be installed in
$GOPATH/bin. If you did not already add the bin directory to your system path during Go installation, we recommend you do so now.
Updating
Windows
Install a newer MSI
Linux/BSD/MacOSX/POSIX - Build from Source
- Run the following commands to update btcd, all dependencies, and install it:
$ cd $GOPATH/src/github.com/btcsuite/btcd
$ git pull && glide install
$ go install . ./cmd/...
Getting Started
btcd has several configuration options avilable to tweak how it runs, but all of the basic operations described in the intro section work with zero configuration.
Windows (Installed from MSI)
Launch btcd from your Start menu.
Linux/BSD/POSIX/Source
$ ./btcd

Issue Tracker
The integrated github issue tracker is used for this project.
Documentation
The documentation is a work-in-progress. It is located in the docs folder.
GPG Verification Key
All official release tags are signed by Conformal so users can ensure the code has not been tampered with and is coming from the btcsuite developers. To verify the signature perform the following:
-
Download the public key from the Conformal website at https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt
-
Import the public key into your GPG keyring:
gpg --import GIT-GPG-KEY-conformal.txt -
Verify the release tag with the following command where
TAG_NAMEis a placeholder for the specific tag:git tag -v TAG_NAME
