      backing: move the min votes threshold to the runtime (#1200) · d6af073a
      Alin Dima authored
      
      * move min backing votes const to runtime
      
      also cache it per-session in the backing subsystem
      
      Signed-off-by: default avataralindima <alin@parity.io>
      
      * add runtime migration
      
      * introduce api versioning for min_backing votes
      
      also enable it for rococo/versi for testing
      
      * also add min_backing_votes runtime calls to statement-distribution
      
      this dependency has been recently introduced by async backing
      
      * remove explicit version runtime API call
      
      this is not needed, as the RuntimeAPISubsystem already takes care
      of versioning and will return NotSupported if the version is not
      right.
      
      * address review comments
      
      - parametrise backing votes runtime API with session index
      - remove RuntimeInfo usage in backing subsystem, as runtime API
      caches the min backing votes by session index anyway.
      - move the logic for adjusting the configured needed backing votes with the size of the backing group
      to a primitives helper.
      - move the legacy min backing votes value to a primitives helper.
      - mark JoinMultiple error as fatal, since the Canceled (non-multiple) counterpart is also fatal.
      - make backing subsystem handle fatal errors for new leaves update.
      - add HostConfiguration consistency check for zeroed backing votes threshold
      - add cumulus accompanying change
      
      * fix cumulus test compilation
      
      * fix tests
      
      * more small fixes
      
      * fix merge
      
      * bump runtime api version for westend and rollback version for rococo

      * Fix `cpu_time_monitor_loop`; fix test
      
      * Fix text
      
      * Fix a couple of potential minor data races.
      
      First data race was due to logging in the CPU monitor thread even if the
      job (other thread) finished. It can technically finish before or after the log.
      
      Maybe best would be to move this log to the `select!`s, where we are guaranteed
      to have chosen the timed-out branch, although there would be a bit of
      duplication.
      
      Also, it was possible for this thread to complete before we executed
      `finished_tx.send` in the other thread, which would trigger an error as the
      receiver has already been dropped. And right now, such a spurious error from
      `send` would be returned even if the job otherwise succeeded.
      
      * Update Cargo.lock

      Reduce dispute coordinator load (#5785) · ca6297c8
      Robert Klotzner authored
      
      * Don't import backing statements directly
      
      into the dispute coordinator. This also gets rid of a redundant
      signature check. Both should have some impact on backing performance.
      In general this PR should make us scale better in the number of parachains.
      
      Reasoning (aka why this is fine):
      
      For the signature check: As mentioned, it is a redundant check. The
      signature has already been checked at this point. This is even made
      obvious by the used types. The smart constructor is not perfect as
      discussed [here](https://github.com/paritytech/polkadot/issues/3455),
      but is still a reasonable security.
      
      For not importing to the dispute-coordinator: This should be good as the
      dispute coordinator does scrape backing votes from chain. This suffices
      in practice as a super majority of validators must have seen a backing
      fork in order for a candidate to get included and only included
      candidates pose a threat to our system. The import from chain is
      preferable over direct import of backing votes for two reasons:
      
      1. The import is batched, greatly improving import performance. All
         backing votes for a candidate are imported with a single import.
         And indeed we were able to see in metrics that importing votes
         from chain is fast.
      2. We do less work in general as not every candidate for which
         statements are gossiped might actually make it on a chain. The
         dispute coordinator as with the current implementation would still
         import and keep those votes around for six sessions.
      
      While redundancy is good for reliability in the event of bugs, this also
      comes at a non negligible cost. The dispute-coordinator right now is the
      subsystem with the highest load, despite the fact that it should not be
      doing much during mormal operation and it is only getting worse
      with more parachains as the load is a direct function of the number of statements.
      
      We'll see on Versi how much of a performance improvement this PR
      
      * Get rid of dead code.
      
      * Dont send approval vote
      
      * Make it pass CI
      
      * Bring back tests for fixing them later.
      
      * Explicit signature check.
      
      * Resurrect approval-voting tests (not fixed yet)
      
      * Send out approval votes in dispute-distribution.
      
      Use BTreeMap for ordered dispute votes.
      
      * Bring back an important warning.
      
      * Fix approval voting tests.
      
      * Don't send out dispute message on import + test
      
      + Some cleanup.
      
      * Guide changes.
      
      Note that the introduced complexity is actually redundant.
      
      * WIP: guide changes.
      
      * Finish guide changes about dispute-coordinator
      
      conceputally. Requires more proof read still.
      
      Also removed obsolete implementation details, where the code is better
      suited as the source of truth.
      
      * Finish guide changes for now.
      
      * Remove own approval vote import logic.
      
      * Implement logic for retrieving approval-votes
      
      into approval-voting and approval-distribution subsystems.
      
      * Update roadmap/implementers-guide/src/node/disputes/dispute-coordinator.md

      * Review feedback.
      
      In particular: Add note about disputes of non included candidates.
      
      * Incorporate Review Remarks
      
      * Get rid of superfluous space.
      
      * Tidy up import logic a bit.
      
      Logical vote import is now separated, making the code more readable and
      maintainable.
      
      Also: Accept import if there is at least one invalid signer that has not
      exceeded its spam slots, instead of requiring all of them to not exceed
      their limits. This is more correct and a preparation for vote batching.
      
      * We don't need/have empty imports.
      
      * Fix tests and bugs.
      
      * Remove error prone redundancy.
      
      * Import approval votes on dispute initiated/concluded.
      
      * Add test for approval vote import.
      
      * Make guide checker happy (hopefully)
      
      * Another sanity check + better logs.
      
      * Reasoning about boundedness.
      
      * Use `CandidateIndex` as opposed to `CoreIndex`.
      
      * Remove redundant import.
      
      * Review remarks.
      
      * Add metric for calls to request signatures
      
      * More review remarks.
      
      * Add metric on imported approval votes.
      
      * Include candidate hash in logs.
      
      * More trace log
      
      * Break cycle.
      
      * Add some tracing.
      
      * Cleanup allowed messages.
      
      * fmt
      
      * Tracing + timeout for get inherent data.
      
      * Better error.
      
      * Break cycle in all places.
      
      * Clarified comment some more.
      
      * Typo.
      
      * Break cycle approval-distribution - approval-voting.
