* sdk: Make PubKey::create_program_address available in program unit tests This finishes the work started in #11604 to have `create_program_address` available when `target_arch` is not `bpf` and `program` is enabled. Otherwise, there is an undefined reference error to `sol_create_program_address`, which is only defined in `bpf`. A small test to simply call the function has been added in order to catch the problem in the future. The default dependency to `solana-sdk/default` doesn't cause a problem with existing programs since `build.sh` always specifies `--no-default-features`, and programs in `solana-program-library` all use it too. * Add `default-features = false` for inter-program dependencies Fix the build error found during CI. The `--no-default-features` flag only applies to the top-level package, and not to dependencies. A program that depends on another program, i.e. `128bit` which depends on `128bit_dep`, must specify `default-features = false` when including that package, otherwise the `bpf` build will try to pull in default packages, which includes `std`.
Building
1. Install rustc, cargo and rustfmt.
$ curl https://sh.rustup.rs -sSf | sh
$ source $HOME/.cargo/env
$ rustup component add rustfmt
If your rustc version is lower than 1.39.0, please update it:
$ rustup update
On Linux systems you may need to install libssl-dev, pkg-config, zlib1g-dev, etc. On Ubuntu:
$ sudo apt-get update
$ sudo apt-get install libssl-dev libudev-dev pkg-config zlib1g-dev llvm clang
2. Download the source code.
$ git clone https://github.com/solana-labs/solana.git
$ cd solana
3. Build.
$ cargo build
4. Run a minimal local cluster.
$ ./run.sh
Testing
Run the test suite:
$ cargo test
Starting a local testnet
Start your own testnet locally, instructions are in the online docs.
Accessing the remote testnet
testnet- public stable testnet accessible via devnet.solana.com. Runs 24/7
Benchmarking
First install the nightly build of rustc. cargo bench requires use of the
unstable features only available in the nightly build.
$ rustup install nightly
Run the benchmarks:
$ cargo +nightly bench
Release Process
The release process for this project is described here.
Code coverage
To generate code coverage statistics:
$ 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!
