      signed wrapper (#1283) · 4f79b770
      Peter Goodspeed-Niklaus authored
      * add signed wrapper, typedef SignedStatement
      * typedef SignedAvailabilityBitfield
      * implement Signed wrapper
      This is strictly an addition as of this commit; nothing is yet
      changed in existing behavior.
      * inline getters, remove review comment
      * move EncodeAs, Signed from node::primitives to primitives::parachain
      * Refactor SignedAvailabilityBitfield to use Signed
      * don't double-encode real payload
      This isn't an ideal solution, because it depends on the
      implementation details of how SCALE encodes tuples, but OTOH
      that behavior seems unlikely to change anytime soon.
      * fix build errors
      * cause the runtime to build properly with the new changes
      Not sure why cargo check didn't catch this earlier; oh well.
      * fix runtime tests and separate SignedStatement from SignedFullStatement
      * better explain why CompactStatement exists

      Convert guide from single markdown file to mdbook (#1247) · e5c7a3e6
      Peter Goodspeed-Niklaus authored
      * move old implementers' guide, add skeleton of new
      * Split the old implementers' guide into the new one's sections
      This is mostly a straightforward copying operation, moving the
      appropriate sections from the old guide to the new. However, there
      are certain differences between the old text and the new:
      - removed horizontal rules between the sections
      - promoted headers appropriately within each section
      - deleted certain sections which were in the old guide's ToC but
        which were not actually present in the old guide.
      - added Peer Set Manager to the new ToC
      * remove description headers
      It is redundant and unnecessary. Descriptions fall directly under the
      top-level header for any given section.
      * add stub description of the backing module
      * add stub description for the availability module
      * add stub description for collators
      * add stub description for validity
      * add stub description for utility
      * highlight TODO and REVIEW comments
      * add guide readme describing how to use mdbook
      * fix markdownlint lints
      * re-title parachains overview
      * internal linking for types
      * module and subsystem internal links
      * .gitignore should have a trailing newline
      * node does not have modules, just subsystems

      expand validity subsystems descriptions independent of subsystems overview (#1185) · bbd49beb
      Peter Goodspeed-Niklaus authored
      * expand subsystems descriptions independent of subsystems overview
      The subsystems overview in https://github.com/paritytech/polkadot/pull/1161
      is a very useful reference for what subsystems need to talk to each other,
      when, and why; it helps us design the actual messages.
      However, administratively, it belongs in a different PR. This commit
      brings in all the changes made there so far as a base for an independent
      * Reorder subsystem descriptions, add some messages
      Update ordering of subsystem descriptions to rough order of use,
      mirroring the order in the overview document.
      Added some message types. Added OverseerSignal variants to several
      types, such that each subsystem only needs to listen for a single
      * add some more message types, Statement Distribution overview
      * add more detail on Statement Distribution, Misbehavior Arbitration
      * intentionally punt MA details for a future PR
      * reduce duplication from overseer signal handling
      * reword for clarity
      * clarify: other modules and subsystems also get to talk to the network
      * finish current work on candidate selection
      * update candidate backing subsystem description according to current thought
      * update mechanism for candidate backing to report collator misbehavior to candidate selection

      * Don't specify 'peer validators', as messages from non-validator peers are ignored regardless

      Add an overview of Validity subsystems (#1161) · 0b8a8b90
      Peter Goodspeed-Niklaus authored
      * migrate subsystem expansion PR from w3f/research
      As the file at this new location included changes not present in
      https://github.com/w3f/research/pull/87, this is effectively a
      rebase, applied manually. I believe that I have successfully retained
      all of, and only, the intended changes.
      * add section on collators
      * note why the overseer is the terminal message point for the validation subsystem
      * add detail about how the validitiy system gets PoV blocks
      * rename to Validity Subsystems Overview
      * get rid of changes to the implementor's guide
      I think it makes most sense to track and review the subsystems
      overview in a different PR than the one which adds content to
      the implementor's guide.
      * punt misbehavior arbitration details to the future
      * empty commit to rerun CI
