      Unfortunately, for reasons that are not yet clear, despite the public key
      and checked data being identical, the signer is not producing an identical
      signature. This commit produces this output (among more):
      
      signing with  Public(c4733ab0bbe3ba4c096685d1737a7f498cdbdd167a767d04a21dc7df12b8c858 (5GWHUNm5...))
      checking with Public(c4733ab0bbe3ba4c096685d1737a7f498cdbdd167a767d04a21dc7df12b8c858 (5GWHUNm5...))
      signed payload:  [4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 10, 0, 0, 0, c7, e5, c0, 64, 7a, db, fe, 44, 81, e5, 51, 11, 79, 9f, a5, 63, 93, 94, 3c, c4, 36, c6, 30, 36, c2, c5, 44, a2, 1b, db, b7, 82, 3, 17, a, 2e, 75, 97, b7, b7, e3, d8, 4c, 5, 39, 1d, 13, 9a, 62, b1, 57, e7, 87, 86, d8, c0, 82, f2, 9d, cf, 4c, 11, 13, 14]
      checked payload: [4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 10, 0, 0, 0, c7, e5, c0, 64, 7a, db, fe, 44, 81, e5, 51, 11, 79, 9f, a5, 63, 93, 94, 3c, c4, 36, c6, 30, 36, c2, c5, 44, a2, 1b, db, b7, 82, 3, 17, a, 2e, 75, 97, b7, b7, e3, d8, 4c, 5, 39, 1d, 13, 9a, 62, b1, 57, e7, 87, 86, d8, c0, 82, f2, 9d, cf, 4c, 11, 13, 14]
      
      * fix broken test
      
      * collation function returns commitments hash
      
      It doesn't look like we use the actual commitments data anywhere, and
      it's not obvious if there are any fields of `CandidateCommitments`
      not available to the collator, so this commit just assigns them the
      entire responsibility of generating the hash.
      
      * add missing overseer impls
      
      * calculating erasure coding is polkadot's responsibility, not cumulus
      
      * concurrentize per-relay_parent requests

      implement provisioner (#1473) · a39d8803
      Peter Goodspeed-Niklaus authored
      * sketch out provisioner basics
      
      * handle provisionable data
      
      * stub out select_inherent_data
      
      * split runtime APIs into sub-chapters to improve linkability
      
      * explain SignedAvailabilityBitfield semantics
      
      * add internal link to further documentation
      
      * some more work figuring out how the provisioner can do its thing
      
      * fix broken link
      
      * don't import enum variants where it's one layer deep
      
      * make request_availability_cores a free fn in util
      
      * document more precisely what should happen on block production
      
      * finish first-draft implementation of provisioner
      
      * start working on the full and proper backed candidate selection rule
      
      * Pass number of block under construction via RequestInherentData
      
      * Revert "Pass number of block under construction via RequestInherentData"
      
      This reverts commit 850fe62c.
      
      That initially looked like the better approach--it spent the time
      budget for fetching the block number in the proposer, instead of
      the provisioner, and that felt more appropriate--but it turns out
      not to be obvious how to get the block number of the block under
      construction from within the proposer. The Chain API may be less
      ideal, but it should be easier to implement.
      
      * wip: get the block under production from the Chain API
      
      * add ChainApiMessage to AllMessages
      
      * don't break the run loop if a provisionable data channel closes
      
      * clone only those backed candidates which are coherent
      
      * propagate chain_api subsystem through various locations
      
      * add delegated_subsystem! macro to ease delegating subsystems
      
      Unfortunately, it doesn't work right:
      
      ```
      error[E0446]: private type `CandidateBackingJob` in public interface
         --> node/core/backing/src/lib.rs:775:1
          |
      86  | struct CandidateBackingJob {
          | - `CandidateBackingJob` declared as private
      ...
      775 | delegated_subsystem!(CandidateBackingJob as CandidateBackingSubsystem);
          | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ can't leak private type
      ```
      
      I'm not sure precisely what's going wrong, here; I suspect the problem is
      the use of `$job as JobTrait>::RunArgs` and `::ToJob`; the failure would be
      that it's not reifying the types to verify that the actual types are public,
      but instead referring to them via `CandidateBackingJob`, which is in fact private;
      that privacy is the point.
      
      Going to see if I can generic my way out of this, but we may be headed for a
      quick revert here.
      
      * fix delegated_subsystem
      
      The invocation is a bit more verbose than I'd prefer, but it's also
      more explicit about what types need to be public. I'll take it as a win.
      
      * add provisioning subsystem; reduce public interface of provisioner
      
      * deny missing docs in provisioner
      
      * refactor core selection per code review suggestion
      
      This is twice as much code when measured by line, but IMO it is
      in fact somewhat clearer to read, so overall a win.
      
      Also adds an improved rule for selecting availability bitfields,
      which (unlike the previous implementation) guarantees that the
      appropriate postconditions hold there.
      
      * fix bad merge double-declaration
      
      * update guide with (hopefully) complete provisioner candidate selection procedure
      
      * clarify candidate selection algorithm
      
      * Revert "clarify candidate selection algorithm"
      
      This reverts commit c68a02ac.
      
      * clarify candidate selection algorithm
      
      * update provisioner to implement candidate selection per the guide
      
      * add test that no more than one bitfield is selected per validator
      
      * add test that each selected bitfield corresponds to an occupied core
      
      * add test that more set bits win conflicts
      
      * add macro for specializing runtime requests; specailize all runtime requests
      
      * add tests harness for select_candidates tests
      
      * add first real select_candidates test, fix test_harness
      
      * add mock overseer and test that success is possible
      
      * add test that the candidate selection algorithm picks the right ones
      
      * make candidate selection test somewhat more stringent

      implement bitfield signing subsystem (#1364) · 8217ca67
      Peter Goodspeed-Niklaus authored
      
      
      * update guide to reduce confusion and TODOs
      
      * work from previous bitfield signing effort
      
      There were large merge issues with the old bitfield signing PR, so
      we're just copying all the work from that onto this and restarting.
      
      Much of the existing work will be discarded because we now have better
      tools available, but that's fine.
      
      * start rewriting bitfield signing in terms of the util module
      
      * implement construct_availability_bitvec
      
      It's not an ideal implementation--we can make it much more concurrent--
      but at least it compiles.
      
      * implement the unimplemented portions of bitfield signing
      
      * get core availability concurrently, not sequentially
      
      * use sp-std instead of std for a parachain item
      
      * resolve type inference failure caused by multiple From impls
      
      * handle bitfield signing subsystem & Allmessages variant in overseer

      It's not clear precisely why this is desired, but it's a pattern
      I've seen in several places, so I'm going this to be on the
      safe side. Worst case, we can revert this commit pretty easily.

      * add sanity check to only include valid inherents
      
      * stub: encapsulate block production mechanics instead of copying them
      
      The goal is to end up with something like what's in
      validation::block_production::*, which encapsulates
      basic block production mechanics. This is a better idea than
      just straight-up copying those mechanics.
      
      * partial implementation of propose fn
      
      Doesn't actually compile yet; need to bring in some other
      commits to ensure ProvisionerMessage is a thing, and also
      figure out how to get the block hash given the current
      context.
      
      * fix compilation
      
      * clear a few more compile errors
      
      * finish fn propose
      
      * broken: add timeout to proposal
      
      * add timeout to proposal
      
      * guide: provisioner is responsible for selecting parachain candidates
      
      * implement ProvisionerMessage::RequestInherentData & update fn propose
      
      * impl CreateProposer::init; clean up
      
      * impl std::error::Error for Error
      
      * document error-handling rationale
      
      * cause polkadot-service-new to compile correctly
      
      * Move potentially-blocking call from fn init -> fn propose
      
      This means that we can wrap the delayed call into the same
      timeout check used elsewhere.
      
      * document struct Proposer
      
      * extract provisioner data fetch
      
      This satisfies two requirements:
      
      - only applies the timeout to actually fetching the provisioner data,
        not to constructing the block after
      - simplifies the problem of injecting default data if we could not
        get the real provisioner data in time.

      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
