As identified by a researcher during the Fusaka security competition, we were computing the proposer index incorrectly in some places by computing without lookahead. - [x] Add "low level" checks to computation functions in `consensus/types` to ensure they error cleanly - [x] Re-work the determination of proposer shuffling decision roots, which are now fork aware. - [x] Re-work and simplify the beacon proposer cache to be fork-aware. - [x] Optimise `with_proposer_cache` to use `OnceCell`. - [x] All tests passing. - [x] Resolve all remaining `FIXME(sproul)`s. - [x] Unit tests for `ProtoBlock::proposer_shuffling_root_for_child_block`. - [x] End-to-end regression test. - [x] Test on pre-Fulu network. - [x] Test on post-Fulu network.

Consensus Specification Tests
This crate parses and executes the test vectors at ethereum/consensus-spec-tests.
Functionality is achieved only via the $ cargo test --features ef_tests command.
Running the Tests
Because the test vectors are very large, we do not download or run them by default. To download them, run (in this directory):
$ make
Note: this may download hundreds of MB of compressed archives from the ethereum/consensus-spec-tests, which may expand into several GB of files.
If successful, you should now have the extracted tests in ./consensus-spec-tests.
Run them with:
$ cargo test --features ef_tests
The tests won't run without the ef_tests feature enabled (this is to ensure that a top-level
cargo test --all won't fail on missing files).
The following is sometimes necessary to avoid stack overflow issues when running on MacOS:
$ export RUST_MIN_STACK=8388608
When debugging failing tests, it's often useful to disable parallization and output suppression:
$ cargo test --features ef_tests,disable_rayon -- --nocapture
Saving Space
When you download the tests, the downloaded archives will be kept in addition to the extracted files. You have several options for saving space:
- Delete the archives (
make clean-archives), and keep the extracted files. Suitable for everyday use, just don't re-runmakeor it will redownload the archives. - Delete the extracted files (
make clean-test-files), and keep the archives. Suitable for CI, or temporarily saving space. If you re-runmakeit will extract the archives rather than redownloading them. - Delete everything (
make clean). Good for updating to a new version, or if you no longer wish to run the EF tests.
