Offchain Phragmén BREAKING. (#4517)
* Initial skeleton for offchain phragmen * Basic compact encoding decoding for results * add compact files * Bring back Self::ensure_storage_upgraded(); * Make staking use compact stuff. * First seemingly working version of reduce, full of todos * Everything phragmen related works again. * Signing made easier, still issues. * Signing from offchain compile fine 😎 * make compact work with staked asssignment * Evaluation basics are in place. * Move reduce into crate. Document stuff * move reduce into no_std * Add files * Remove other std deps. Runtime compiles * Seemingly it is al stable; cycle implemented but not integrated. * Add fuzzing code. * Cleanup reduce a bit more. * a metric ton of tests for staking; wip 🔨 * Implement a lot more of the tests. * wip getting the unsigned stuff to work * A bit gleanup for unsigned debug * Clean and finalize compact code. * Document reduce. * Still problems with signing * We officaly duct taped the transaction submission stuff. 🤓 * Deadlock with keys again * Runtime builds * Unsigned test works 🙌 * Some cleanups * Make all the tests compile and stuff * Minor cleanup * fix more merge stuff * Most tests work again. * a very nasty bug in reduce * Fix all integrations * Fix more todos * Revamp everything and everything * Remove bogus test * Some review grumbles. * Some fixes * Fix doc test * loop for submission * Fix cli, keyring etc. * some cleanup * Fix staking tests again * fix per-things; bring patches from benchmarking * better score prediction * Add fuzzer, more patches. * Some fixes * More docs * Remove unused generics * Remove max-nominator footgun * Better fuzzer * Disable it ❌ * Bump. * Another round of self-review * Refactor a lot * More major fixes in perThing * Add new fuzz file * Update lock * fix fuzzing code. * Fix nominator retain test * Add slashing check * Update frame/staking/src/tests.rs Co-Authored-By: Joshy Orndorff <JoshOrndorff@users.noreply.github.com> * Some formatting nits * Review comments. * Fix cargo file * Almost all tests work again * Update frame/staking/src/tests.rs Co-Authored-By: thiolliere <gui.thiolliere@gmail.com> * Fix review comments * More review stuff * Some nits * Fix new staking / session / babe relation * Update primitives/phragmen/src/lib.rs Co-Authored-By: thiolliere <gui.thiolliere@gmail.com> * Update primitives/phragmen/src/lib.rs Co-Authored-By: thiolliere <gui.thiolliere@gmail.com> * Update primitives/phragmen/compact/src/lib.rs Co-Authored-By: thiolliere <gui.thiolliere@gmail.com> * Some doc updates to slashing * Fix derive * Remove imports * Remove unimplemented tests * nits * Remove dbg * Better fuzzing params * Remove unused pref map * Deferred Slashing/Offence for offchain Phragmen (#5151) * Some boilerplate * Add test * One more test * Review comments * Fix build * review comments * fix more * fix build * Some cleanups and self-reviews * More minor self reviews * Final nits * Some merge fixes. * opt comment * Fix build * Fix build again. * Update frame/staking/fuzz/fuzz_targets/submit_solution.rs Co-Authored-By: Gavin Wood <gavin@parity.io> * Update frame/staking/src/slashing.rs Co-Authored-By: Gavin Wood <gavin@parity.io> * Update frame/staking/src/offchain_election.rs Co-Authored-By: Gavin Wood <gavin@parity.io> * Fix review comments * fix test * === 🔑 Revamp without staking key. * final round of changes. * Fix cargo-deny * Update frame/staking/src/lib.rs Co-Authored-By: Gavin Wood <gavin@parity.io> Co-authored-by: Joshy Orndorff <JoshOrndorff@users.noreply.github.com> Co-authored-by: thiolliere <gui.thiolliere@gmail.com> Co-authored-by: Gavin Wood <gavin@parity.io>
