# Building
|
|
|
|
## **1. Install rustc, cargo and rustfmt.**
|
|
|
|
```bash
|
|
$ curl https://sh.rustup.rs -sSf | sh
|
|
$ source $HOME/.cargo/env
|
|
$ rustup component add rustfmt
|
|
```
|
|
|
|
When building the master branch, please make sure you are using the latest stable rust version by running:
|
|
|
|
```bash
|
|
$ rustup update
|
|
```
|
|
|
|
When building a specific release branch, you should check the rust version in `ci/rust-version.sh` and if necessary, install that version by running:
|
|
```bash
|
|
$ rustup install VERSION
|
|
```
|
|
Note that if this is not the latest rust version on your machine, cargo commands may require an [override](https://rust-lang.github.io/rustup/overrides.html) in order to use the correct version.
|
|
|
|
On Linux systems you may need to install libssl-dev, pkg-config, zlib1g-dev, protobuf etc. On Ubuntu:
|
|
|
|
```bash
|
|
$ sudo apt-get update
|
|
$ sudo apt-get install libssl-dev libudev-dev pkg-config zlib1g-dev llvm clang cmake make libprotobuf-dev protobuf-compiler
|
|
```
|
|
|
|
## **2. Download the source code.**
|
|
|
|
```bash
|
|
$ git clone https://github.com/solana-labs/solana.git
|
|
$ cd solana
|
|
```
|
|
|
|
## **3. Build.**
|
|
|
|
```bash
|
|
$ cargo build
|
|
```
|
|
|
|
# Testing
|
|
|
|
**Run the test suite:**
|
|
|
|
```bash
|
|
$ cargo test
|
|
```
|
|
|
|
### Starting a local testnet
|
|
Start your own testnet locally, instructions are in the [online docs](https://docs.solana.com/cluster/bench-tps).
|
|
|
|
### Accessing the remote development cluster
|
|
* `devnet` - stable public cluster for development accessible via
|
|
devnet.solana.com. Runs 24/7. Learn more about the [public clusters](https://docs.solana.com/clusters)
|
|
|
|
# Benchmarking
|
|
|
|
First, install the nightly build of rustc. `cargo bench` requires the use of the
|
|
unstable features only available in the nightly build.
|
|
|
|
```bash
|
|
$ rustup install nightly
|
|
```
|
|
|
|
Run the benchmarks:
|
|
|
|
```bash
|
|
$ cargo +nightly bench
|
|
```
|
|
|
|
# Release Process
|
|
|
|
The release process for this project is described [here](RELEASE.md).
|
|
|
|
# Code coverage
|
|
|
|
To generate code coverage statistics:
|
|
|
|
```bash
|
|
$ scripts/coverage.sh
|
|
$ open target/cov/lcov-local/index.html
|
|
```
|
|
|
|
Why coverage? While most see coverage as a code quality metric, we see it primarily as a developer
|
|
productivity metric. When a developer makes a change to the codebase, presumably it's a *solution* to
|
|
some problem. Our unit-test suite is how we encode the set of *problems* the codebase solves. Running
|
|
the test suite should indicate that your change didn't *infringe* on anyone else's solutions. Adding a
|
|
test *protects* your solution from future changes. Say you don't understand why a line of code exists,
|
|
try deleting it and running the unit-tests. The nearest test failure should tell you what problem
|
|
was solved by that code. If no test fails, go ahead and submit a Pull Request that asks, "what
|
|
problem is solved by this code?" On the other hand, if a test does fail and you can think of a
|
|
better way to solve the same problem, a Pull Request with your solution would most certainly be
|
|
welcome! Likewise, if rewriting a test can better communicate what code it's protecting, please
|
|
send us that patch!

# Disclaimer
|
|
|
|
All claims, content, designs, algorithms, estimates, roadmaps,

specifications, and performance measurements described in this project
|
|
are done with the Solana Foundation's ("SF") good faith efforts. It is up to
|
|
the reader to check and validate their accuracy and truthfulness.
|
|
Furthermore, nothing in this project constitutes a solicitation for
|
|
investment.
|
|
|
|
Any content produced by SF or developer resources that SF provides are

|
for educational and inspirational purposes only. SF does not encourage,
|
|
induce or sanction the deployment, integration or use of any such
|
|
applications (including the code comprising the Solana blockchain
|
|
protocol) in violation of applicable laws or regulations and hereby
|
|
prohibits any such deployment, integration or use. This includes the use of
|
|
any such applications by the reader (a) in violation of export control
|
|
or sanctions laws of the United States or any other applicable
|
|
jurisdiction, (b) if the reader is located in or ordinarily resident in
|
|
a country or territory subject to comprehensive sanctions administered
|
|
by the U.S. Office of Foreign Assets Control (OFAC), or (c) if the
|
|
reader is or is working on behalf of a Specially Designated National
|
|
(SDN) or a person subject to similar blocking or denied party
|
|
prohibitions.
|
|
|
|
The reader should be aware that U.S. export control and sanctions laws
|
|
prohibit U.S. persons (and other persons that are subject to such laws)
|
|
from transacting with persons in certain countries and territories or
|
|
that are on the SDN list. As a project-based primarily on open-source
|
|
software, it is possible that such sanctioned persons may nevertheless
|
|
bypass prohibitions, obtain the code comprising the Solana blockchain
|
|
protocol (or other project code or applications) and deploy, integrate,
|
|
or otherwise use it. Accordingly, there is a risk to individuals that
|
|
other persons using the Solana blockchain protocol may be sanctioned
|
|
persons and that transactions with such persons would be a violation of
|
|
U.S. export controls and sanctions law. This risk applies to
|
|
individuals, organizations, and other ecosystem participants that
|
|
deploy, integrate, or use the Solana blockchain protocol code directly
|
|
(e.g., as a node operator), and individuals that transact on the Solana
|
|
blockchain through light clients, third party interfaces, and/or wallet
|
|
software.
