BABE Epochs (#3028)
* Add `epoch` field to `SlotInfo` * Add slot calculations * More work on epochs in BABE * Apply suggestions from code review Co-Authored-By: Bastian Köcher <bkchr@users.noreply.github.com> * Typo: `/` not `%` for division * Delete useless `LastSlotInEpoch::put(false)` * Bump `spec_version` * Make test suite pass again * Implement BABE epoch randomness signing * Try to fix compilation Currently causes a stack overflow in the compiler * Fix rustc stack overflow * Add missing `PartialEq` and `Eq` implementations * Fix compile errors in test suite * Another silly compile error * Clone `epoch` * Fix compile error in benchmarks * Implement `clone` for `Epoch` * Merge master * AUTHORING TEST PASSES!!! * Fix compilation * Bump `spec_version` * Fix compilation * Fix compilation (again) * Remove an outdated FIXME * Fix run.sh and move it to scripts/ * Delete commented-out code * Fix documentation Co-Authored-By: André Silva <andre.beat@gmail.com> * Fix BABE initialization and refactor * Respond to review * typo * Remove useless data in `CheckedHeader::Deferred` * Remove `slot_number` from Epoch It is not needed, and only served to waste space and cause confusion. * Remove epoch from BABE digests * Move digest.rs to primitives * Fix incorrect warning names * Fix compile error * Consistent field naming for BABE digests * More compiler error fixex * Unbound variable * more compile errors * another compile error * Fix compile errors in runtime * another compile error * Another compile error * Fix wasm build * missing import * Fix more compile errors * yet another compile error * compile fix in test runtime * Fix and simplify the BABE runtime The BABE runtime was massively overcomplicated and also wrong. It assumed it needed to: 1. delay new authorities taking effect until the next epoch 2. not delay emitting `Consensus` digests to mark epoch changes However, the first is handled by the `srml_session` crate, and the second is flat-out incorrect: `Consensus` digests take effect immediately. Furthermore, `srml_babe` tried to duplicate the functionality of `srml_session::PeriodicSession`, but did it both clumsily and incorrectly. Fortunately, the new code is simpler and far more likely to be correct. * Use `system` to get the test authorities The genesis block used by tests defines no authorities. Only the test suite is affected. * Fix test runtime impl for BabeApi::epoch() with std * Fix compilation * Cached authorities are in the form of an epoch not a `Vec<AuthorityId>`. * `slots_per_epoch` is not fixed in general The BABE code previously assumed `slots_per_epoch` to be a constant, but that assumption is false in general. Furthermore, removing this assumption also allows a lot of code to go away. * fix compile error * Implement epoch checker * Fix runtime compilation * fork-tree: add method for finding a node in the tree * babe: register epoch transitions in fork tree and validate them * fork-tree: add method for arbitrary pruning * Expose the queued validator set to SRML modules BABE needs to know not only what the current validator set is, but also what the next validator set will be. Expose this to clients of the session module. * Bump hex-literal Hopefully this will fix the panic * babe: prune epoch change fork tree on finality * babe: validate epoch index on transition * babe: persist epoch changes tree * Fix compile error in tests * Fix compile error in tests * Another compile error in tests * Fix compilation of tests * core: move grandpa::is_descendent_of to client utils * babe: use is_descendent_of from client utils * babe: extract slot_number from pre_digest in import_block * Move BABE testsuite to its own file * Initial part of test code * Missing `WeightMultiplierUpdate` in test-runtime * bump `spec_version` * Add a test that a very bogus is rejected * Run the tests again * Fix compiler diagnostics * Bump `spec_version` * Initial infrastructure for mutation testing * Mutation testing of block import * babe: revert epoch changes in case of block import error * babe: fix logging target * babe: BabeBlockImport doesn't box inner BlockImport * babe: fix epoch check in block import * babe: populate authorities cache on block authorship * babe: remove unused functions * babe: use RANDOMNESS_LENGTH const * babe: remove unneeded config parameters * core: revert change to hex dependency version * cleanup gitignore * babe: add docs to aux_schema * babe: remove useless drops in tests * babe: remove annoying macos smart quotes * fork-tree: docs * fork-tree: add tests * babe: style * babe: rename randomness config variable * babe: remove randomness helper function * babe: style fixes * babe: add docs * babe: fix tests * node: bump spec_version * babe: fix tests |

BABE Randomness using PreRuntime digests (#2929)
* Initial work on exposing pre-runtime digests
This provides the primitive API, as well as exposing it from BABE.
* Initial work on using pre-digests in runtimes
This includes both code to expose them from `srml_system`, as well as
using it in (currently dead) code in `srml_babe`.
* Bump `{spec,impl}_version`
* Add `u64_backend` feature to curve25519-dalek
Otherwise, it errors out at compile-time.
* Bump `Cargo.lock`
* Do not depend on the schnorrkel crate in the runtime
The schnorrkel crate does not work on `#![no_std]`, but the runtime only
needs constants from it. This adds our own definitions of those
constants, and checks them for correctness at compile-time.
* Actually implement storage of VRF outputs
* Trivial formatting change
* Provide a `hash_randomness` function in BABE
for processing VRF outputs.
* Implement a basic randomness generating function
It just XORs the VRF outputs together.
* Actually implement on-chain randomness
Blake2b is used for hashing.
* Update dependencies
* Run `cargo update` where needed
* Re-add a newline at EOF
* Remove broken and unsafe code
XOR is not a hash function, and must not be used as such. The
implementation was also needlessly unsafe.
* Run `cargo update` where needed
* Remove spurious dependency
* Document security guarantees of BABE randomness
* Add a `RandomnessBeacon` trait
* Document `RandomnessBeacon::random`
* Fix silly compile error (unexpected type arguments)
* Fix BABE randomness
* Implement `FindAuthor` for `babe::Module`
* Apply suggestions from code review
Co-Authored-By: Bastian Köcher <bkchr@users.noreply.github.com>
Co-Authored-By: Robert Habermeier <rphmeier@gmail.com>
* Respond to suggestions from code review and fix bugs
* Store an authority index, not the authority itself.
* Avoid unnecessary decoding.
* Implement relative slots and BABE randomness fully and correctly.
* Remove spurious dependency
* Fix error reported by rust-analyzer
* Update Cargo.lock files
* `wrapping_add` → `checked_add`
The epoch index will not overflow. Panic if it does.
* Move randomness documentation to trait
* Fix compile error in test suite
* Explain 2^64 limit

BABE signing and verification (#2270)
* Add basic BABE consensus type * Update core/consensus/babe/slots/Cargo.toml Co-Authored-By: DemiMarie-parity <48690212+DemiMarie-parity@users.noreply.github.com> * Fix parameterization and run `rustfmt` * Respond to review comments * Update various Cargo.lock files * Revert "Update various Cargo.lock files" This reverts commit af53d7624752a744320e9cbb25749fdd8e6f46d2. * `BabeSealSignature` → `BabeSeal` * Move slot code to its own crate This was highly non-trivial, due to cyclic dependencies. * Remove redundancy between AuRa and BABE Some of the code duplication was removed using a macro. * Fix build error * Avoid non-`#[doc(hidden)]` re-exports Also, bump some library versions in `Cargo.toml`. * Remove dead code in AuRa * Remove impl_slot macro It was more trouble than it was worth. Also, delete useless dependencies on Serde. * AuRa and BABE need different DB keys * Bring back `aura::Network`, but deprecate it. * Improve docs and add `slot_duration` inherent method * Add docs to `substrate_consensus_aura::SlotDuration` * Add missing documentation and #![forbid(missing_docs, unsafe_code)] * Add a #![forbid(missing_docs)] * Remove dependency of `test-runtime` on `slots` * Update core/consensus/babe/src/lib.rs Co-Authored-By: DemiMarie-parity <48690212+DemiMarie-parity@users.noreply.github.com> * Remove wrongly added file * Fix copyright notice Co-Authored-By: DemiMarie-parity <48690212+DemiMarie-parity@users.noreply.github.com> * Bump `impl_version` and `spec_version` * Add more code to BABE Most of it is copied from AuRa code, but at least the initial core is there. * Stuck on horrible compiler error message * add missing files * Spaces → tabs * Simplify code * Fix compilation This involved fixing dependencies and adding a `Mutex`. * More work on BABE * Fix deprecation version * Fix deprecation version; remove spurious carets * Fix Cargo.toml * Implement VRF signing logic * The import queue code compiles, though it probably doesn’t work. * Add VRF verification * Update Cargo.lock * Update dependencies * Move test network to sr25519 authority keys * Fix accidental build bustage * Trying to get the tests to work * Add logging messages and remove dead code There seems to be a problem with the test network. Since AuRa and BABE are both affected, this is most likely due to the switch from ed25519 to sr25519. * Trying to get the tests to work * Add logging messages and remove dead code There seems to be a problem with the test network. Since AuRa and BABE are both affected, this is most likely due to the switch from ed25519 to sr25519. * Working testsuite at last! The problem was with serialization and deserialization. Normally, those functions are generated automatically, but those for `BabeSeal` had to be written manually. The hand-written versions were not correct, however, as shown by the decoder not being able to decode the output of the encoder. * Enable BabeSeal::Encode asserts in --release tests * Bump runtime and dependency versions * Fix wasm compilation The wasm build was broken because of a typo in `core/test-runtime/src/lib.rs`, and missing gates on the `std` feature in `core/consensus/{aura,babe}/primitives/Cargo.toml`. Additionally, improve the quotation in the build scripts. * Merge Cargo.lock * Change expected JSON string The test was also broken on `master`, so I suspect that the test was incorrect. * Responded to review * Remove hard-coded threshold from production code A hard-coded threshold is now only used in tests. * Fix swapped doc comments * Fix unused import warnings * fix ci error * fix typo * Fix spacing in docs * Minor changes suggested by @joepetrowski on https://github.com/paritytech/substrate/pull/2372 * Remove unnecessary getters * fix compile error * Fix silly unused-variable error * Improve documentation formatting Co-Authored-By: DemiMarie-parity <48690212+DemiMarie-parity@users.noreply.github.com> * Add issue links * Revert excess verbosity and #![forbid(warnings)] * Apply suggestions from code review Co-Authored-By: DemiMarie-parity <48690212+DemiMarie-parity@users.noreply.github.com> * Reformat some comments * Threshold should depend on number of validators Also, respond to code review * Fix silly compilation errors * Reduce logging verbosity * Fix missing import |
