      start working on building the real overseer (#1795) · 798f781f
      Peter Goodspeed-Niklaus authored
      
      
      * start working on building the real overseer
      
      Unfortunately, this fails to compile right now due to an upstream
      failure to compile which is probably brought on by a recent upgrade
      to rustc v1.47.
      
      * fill in AllSubsystems internal constructors
      
      * replace fn make_metrics with Metrics::attempt_to_register
      
      * update to account for #1740
      
      * remove Metrics::register, rename Metrics::attempt_to_register
      
      * add 'static bounds to real_overseer type params
      
      * pass authority_discovery and network_service to real_overseer
      
      It's not straightforwardly obvious that this is the best way to handle
      the case when there is no authority discovery service, but it seems
      to be the best option available at the moment.
      
      * select a proper database configuration for the availability store db
      
      * use subdirectory for av-store database path
      
      * apply Basti's patch which avoids needing to parameterize everything on Block
      
      * simplify path extraction
      
      * get all tests to compile
      
      * Fix Prometheus double-registry error
      
      for debugging purposes, added this to node/subsystem-util/src/lib.rs:472-476:
      
      ```rust
      Some(registry) => Self::try_register(registry).map_err(|err| {
      	eprintln!("PrometheusError calling {}::register: {:?}", std::any::type_name::<Self>(), err);
      	err
      }),
      ```
      
      That pointed out where the registration was failing, which led to
      this fix. The test still doesn't pass, but it now fails in a new
      and different way!
      
      * authorities must have authority discovery, but not necessarily overseer handlers
      
      * fix broken SpawnedSubsystem impls
      
      detailed logging determined that using the `Box::new` style of
      future generation, the `self.run` method was never being called,
      leading to dropped receivers / closed senders for those subsystems,
      causing the overseer to shut down immediately.
      
      This is not the final fix needed to get things working properly,
      but it's a good start.
      
      * use prometheus properly
      
      Prometheus lets us register simple counters, which aren't very
      interesting. It also allows us to register CounterVecs, which are.
      With a CounterVec, you can provide a set of labels, which can
      later be used to filter the counts.
      
      We were using them wrong, though. This pattern was repeated in a
      variety of places in the code:
      
      ```rust
      // panics with an cardinality mismatch
      let my_counter = register(CounterVec::new(opts, &["succeeded", "failed"])?, registry)?;
      my_counter.with_label_values(&["succeeded"]).inc()
      ```
      
      The problem is that the labels provided in the constructor are not
      the set of legal values which can be annotated, but a set of individual
      label names which can have individual, arbitrary values.
      
      This commit fixes that.
      
      * get av-store subsystem to actually run properly and not die on first signal
      
      * typo fix: incomming -> incoming
      
      * don't disable authority discovery in test nodes
      
      * Fix rococo-v1 missing session keys
      
      * Update node/core/av-store/Cargo.toml
      
      * try dummying out av-store on non-full-nodes
      
      * overseer and subsystems are required only for full nodes
      
      * Reduce the amount of warnings on browser target
      
      * Fix two more warnings
      
      * InclusionInherent should actually have an Inherent module on rococo
      
      * Ancestry: don't return genesis' parent hash
      
      * Update Cargo.lock
      
      * fix broken test
      
      * update test script: specify chainspec as script argument
      
      * Apply suggestions from code review

      * 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

      add simple name derivation heuristic for JobManager Subsystem impl (#1490) · ef29680b
      Peter Goodspeed-Niklaus authored
      Subsystems are encouraged to either typedef themselves as appropriate
      `JobManager` instances for their job type, or wrap a `JobManager`
      instance and delegate the `Subsystem` impl. In both cases, we want
      to use a sensible, non-repeated subsystem name for appropriate
      logging and debugging.
      
      This PR adds a heuristic: if the job name ends in the literal
      "Job", then that gets stripped. Otherwise, the job name is used.
      This improves on the previous situation, in which subsystems
      typedef'd to or wrapping `JobManager` all got the same constant (!)
      name.

      Add test suite and minor refinements to the utility subsystem (#1403) · cc2d7afd
      Peter Goodspeed-Niklaus authored
      * get conclude signal working properly; don't allocate a vector
      
      * wip: add test suite / example / explanation for using utility subsystem
      
      Unfortunately, the test fails right now for reasons which seem
      very odd. Just have to keep poking at it.
      
      * explicitly import everything
      
      * fix subsystem-util test
      
      The root problem here was two-fold:
      
      - there was a circular dependency from subsystem -> test-helpers/subsystem ->
        subsystem
      - cfg(test) doesn't propagate between crates
      
      The solution: move the subsystem test helpers into a sub-module
      within subsystem. Publicly export them from the previous location
      so no other code breaks.
      
      Doing this has an additional benefit: it ensures that no production
      code can ever accidentally use the subsystem helpers, as they are compile-
      gated on cfg(test).
      
      * fully commit to moving test helpers into a subsystem module
      
      * add some more tests
      
      * get rid of log tests in favor of real error forwarding
      
      It's not obvious whether we'll ever really want to chase down
      these errors outside a testing context, but having the capability
      won't hurt.
      
      * fix issue which caused test to hang on osx
      
      * only require that job errors are PartialEq when testing
      
      also fix polkadot-node-core-backing tests
      
      * get rid of any notion of partialeq
      
      * rethink testing
      
      Combine tests of starting and stopping job: leaving a test executor
      with a job running was pretty clearly the cause of the sometimes-hang.
      
      Also, add a timeout so tests _can't_ hang anymore; they just fail
      after a while.
      
      * rename fwd_errors -> forward_errors
      
      * warn on error propagation failure
      
      * fix unused import leftover from merge
      
      * derive eq for subsystemerror

      mod subsystem-util (#1376) · d7684115
      Peter Goodspeed-Niklaus authored
      * Add subsystem-util crate.
      
      Start by moving the JobCanceler here.
      
      * copy utility functions for requesting runtime data; generalize
      
      * convert subsystem-util from crate to module in subsystem
      
      The point of making a sub-crate is to ensure that only the necessary
      parts of a program get compiled; if a dependent package needed only
      subsystem-util, and not subsystem, then subsystem wouldn't need to
      be compiled.
      
      However, that will never happen: subsystem-util depends on
      subsystem::messages, so subsystem will always be compiled.
      
      Therefore, it makes more sense to add it as a module in the existing
      crate than as a new and distinct crate.
      
      * make runtime request sender type generic
      
      * candidate backing subsystem uses util for api requests
      
      * add struct Validator representing the local validator
      
      This struct can be constructed when the local node is a validator;
      the constructor fails otherwise. It stores a bit of local data, and
      provides some utility methods.
      
      * add alternate constructor for better efficiency
      
      * refactor candidate backing to use utility methods
      
      * fix test breakage caused by reordering tests
      
      * restore test which accidentally got deleted during merge
      
      * start extracting jobs management into helper traits + structs
      
      * use util::{JobHandle, Jobs} in CandidateBackingSubsystem
      
      * implement generic job-manager subsystem impl
      
      This means that the work of implementing a subsystem boils down
      to implementing the job, and then writing an appropriate
      type definition, i.e.
      
      pub type CandidateBackingSubsystem<Spawner, Context> =
      	util::JobManager<Spawner, Context, CandidateBackingJob>;
      
      * add hash-extraction helper to messages
      
      * fix errors caused by improper rebase
      
      * doc improvement
      
      * simplify conversion from overseer communication to job message
      
      * document fn hash for all messages
      
      * rename fn hash() -> fn relay_parent
      
      * gracefully shut down running futures on Conclude
      
      * ensure we're validating with the proper validator index
      
      * rename: handle_unhashed_msg -> handle_orphan_msg
      
      * impl Stream for Jobs<Spawner, Job>
      
      This turns out to be relatively complicated and requires some
      unsafe code, so we'll want either detailed review, or to choose
      to revert this commit.
      
      * add missing documentation for public items
      
      * use pin-project to eliminate unsafe code from this codebase
      
      * rename SenderMessage -> FromJob
      
      * reenvision the subsystem requests as an extension trait
      
      This works within `util.rs`, but fails in `core/backing/src/lib.rs`,
      because we don't actually create the struct soon enough. Continuing
      down this path would imply substantial rewriting.
      
      * Revert "reenvision the subsystem requests as an extension trait"
      
      This reverts commit a5639e36.
      
      The fact is, the new API is more complicated to no real benefit.
      
      * apply suggested futuresunordered join_all impl
      
      * CandidateValidationMessage variants have no top-level relay parents
      
      * rename handle_orphan_msg -> handle_unanchored_msg
      
      * make most node-core-backing types private
      
      Now the only public types exposed in that module are
      CandidateBackingSubsystem and ToJob. While ideally we could reduce
      the public interface to only the former type, that doesn't work
      because ToJob appears in the public interface of CandidateBackingSubsystem.
      
      This also involves changing the definition of CandidateBackingSubsystem;
      it is no longer a typedef, but a struct wrapping the job manager.
