* When there are too many pubkeys in one slot, kick the one with lowest stake out. * Cache last_root to reduce read locks we need. * Use slots_in_epoch to limit number of slots in the map. * Fix lint errors. * Only cache stake and slots per epoch once per epoch. * Revert "Only cache stake and slots per epoch once per epoch." This reverts commit 8658aad0083456794b4c4403adaf9c74d1a71d09. * Vote at the tip of current fork if last vote is outside SlotHash of the tip and last vote expired. * Add unittest when last vote is outside slothash, we should vote at the tip of the current fork. * Revert "Use slots_in_epoch to limit number of slots in the map." This reverts commit 93574f57a48d2a70fbbc0f62fa8810d3b6bee0af. * Revert "Cache last_root to reduce read locks we need." This reverts commit bb114ec2b62cb9c0207328b19c415f6116be0f1c. * Revert "When there are too many pubkeys in one slot, kick the one with lowest" This reverts commit 711e29a6a025fd4f11fbc97dcbbe90e4832be04c. * Move new vote generation when last vote is outside slothash into the main path, this actually makes more sense since we don't select where to vote in two different places, and all the vote generation logic is seamlessly inherited. * - Move vote refresh to be behind select vote and do not refresh vote if a new vote is selected. - Check whether last vote is inside slothash inside select_vote_and_reset_forks - rename slot_within_slothash to is_in_slothashes_history - remove one unittest for now, more tests will be added in a separate CL * Remove new test, it will be in another file. * Add is_in_slot_hashes_history test in the new file. * Add unittest for the case when last vote is outside slot hashes. * Small improvements and more unittests. * Fix bad merge. * Update docs/src/terminology.md Co-authored-by: mvines <mvines@gmail.com> * Put SwitchForkDecision::FailedSwitchThreshold logic into separate function. * Make linter happy. --------- Co-authored-by: mvines <mvines@gmail.com> |

Building
1. Install rustc, cargo and rustfmt.
$ 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:
$ 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:
$ rustup install VERSION
Note that if this is not the latest rust version on your machine, cargo commands may require an override 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:
$ sudo apt-get update
$ sudo apt-get install libssl-dev libudev-dev pkg-config zlib1g-dev llvm clang cmake make libprotobuf-dev protobuf-compiler
On Fedora:
$ sudo dnf install openssl-devel systemd-devel pkg-config zlib-devel llvm clang cmake make protobuf-devel protobuf-compiler perl-core
2. Download the source code.
$ git clone https://github.com/solana-labs/solana.git
$ cd solana
3. Build.
$ ./cargo build
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 development cluster
devnet
- stable public cluster for development accessible via devnet.solana.com. Runs 24/7. Learn more about the public clusters
Benchmarking
First, install the nightly build of rustc. cargo bench
requires the 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!
