      *: Disable authority discovery module (#3914) · 5c505d19
      Max Inden authored
      The authority discovery module enables authorities to be discoverable
      and discover other authorities to improve interconnection among them. In
      order to achieve this the module needs to know when the authority set
      changes, thus when a session changes.
      
      One has to register a module as a *session handler* in order for it to
      be notified of changing sessions. The order and number of these *session
      handlers* **MUST** correspond to the order and number of the *session
      keys*.
      
      Commit 7fc21cea added the authority discovery to the `SessionHandlers`.
      Given that the authority discovery module piggybacks on the Babe session
      keys the commit violated the above constraint.
      
      This commit reverts most of 7fc21cea, leaving `core/authority-discovery`
      and `srml/authority-discovery` untouched.

      Fixes for allocator + factory + misc improvements (#3534) · ddb8512a
      Michael Müller authored
      
      
      * Clear up import/export misunderstandings
      
      * Fetch minimum period from runtime
      
      * Remove unnecessary comment
      
      This variable is already fetched from the runtime
      in the line below.
      
      * Fix bug in factory
      
      The `best_block_id` stayed the same, it was always the
      genesis hash. This resulted in the factory failing after
      4096 blocks, since `client/db` discards hashes (in this
      case the genesis hash) after 4096 blocks from the database.
      
      * Fix tense in error message
      
      * Improve allocator documentation
      
      * Fix bug in allocator
      
      Under certain circumstances an invalid pointer was
      returned: when the `ptr` was calculated as equal
      to the `max_heap_size`. This is an invalid pointer
      since there is no access allowed after the heap limit.
      
      The way to provoke this was to repeatedly allocate
      with sizes which were previously not allocated and
      immediately deallocate right afterwards. What this
      did was to increment the `bumper` with each allocation,
      whilst keeping the `total_size` of the heap `0`.
      If this repeated allocation/deallocation scheme resulted
      in `max_heap_size == ptr` the `ptr` was still returned.
      
      The allocator only checked if the `total_size` was
      still within the `max_heap_size` limits, and not
      if the resulting `ptr` was still within the valid
      heap region.
      
      This commit introduces a check to validate if the
      calculated `ptr` is within the heap.
      
      * Add test for zero byte allocation and document behavior
      
      * Improve code readability by introducing a const

      core/authority-discovery: Enable authorities to discover each other (#3452) · 7fc21cea
      Max Inden authored
      With the *authority-discovery* module an authoritative node makes itself
      discoverable and is able to discover other authorities. Once discovered, a node
      can directly connect to other authorities instead of multi-hop gossiping
      information.
      
      1. **Making itself discoverable**
      
          1. Retrieve its external addresses
      
          2. Adds its network peer id to the addresses
      
          3. Sign the above
      
          4. Put the signature and the addresses on the libp2p Kademlia DHT
      
      2. **Discovering other authorities**
      
          1. Retrieve the current set of authorities
      
          2. Start DHT queries for the ids of the authorities
      
          3. Validate the signatures of the retrieved key value pairs
      
          4. Add the retrieved external addresses as ~reserved~ priority nodes to the
             peerset
      
      
      * node/runtime: Add authority-discovery as session handler
      
      The srml/authority-discovery module implements the OneSessionHandler in
      order to keep its authority set in sync. This commit adds the module to
      the set of session handlers.
      
      * core/network: Make network worker return Dht events on poll
      
      Instead of network worker implement the Future trait, have it implement
      the Stream interface returning Dht events.
      
      For now these events are ignored in build_network_future but will be
      used by the core/authority-discovery module in subsequent commits.
      
      * *: Add scaffolding and integration for core/authority-discovery module
      
      * core/authority-discovery: Implement module logic itself

      Service factory refactor (#3382) · d14e727b
      Pierre Krieger authored
      * Move Service::new to a macro
      
      * Move function calls to macros
      
      * Extract offchain_workers and start_rpc in separate function
      
      In follow-up commits, we want to be able to directly call maintain_transaction_pool, offchain_workers, and start_rpc, without having to implement the Components trait.
      This commit is a preliminary step: we extract the code to freestanding functions.
      
      * Introduce an AbstractService trait
      
      * Introduce NewService as an implementation detail of Service
      
      * Implement traits on NewService instead
      
      Instead of implementing AbstractService, Future, and Executor on Service, we implement them on NewService instead.
      
      The implementations of AbstractService, Future, and Executor on Service still exist, but they just wrap to the respective implementations for NewService.
      
      * Move components creation back to macro invocation
      
      Instead of having multiple $build_ parameters passed to the macro, let's group them all into one.
      
      This change is necessary for the follow-up commits, because we are going to call new_impl! only after all the components have already been built.
      
      * Add a $block parameter to new_impl
      
      This makes it possible to be explicit as what the generic parameter of the NewServiceis, without relying on type inference.
      
      * Introduce the ServiceBuilder struct
      
      Introduces a new builder-like ServiceBuilder struct that creates a NewService.
      
      * Macro-ify import_blocks, export_blocks and revert_chain
      
      Similar to the introduction of new_impl!, we extract the actual code into a macro, letting us get rid of the Components and Factory traits
      
      * Add export_blocks, import_blocks and revert_chain methods on ServiceBuilder
      
      Can be used as a replacement for the chain_ops::* methods
      
      * Add run_with_builder
      
      Instead of just run, adds run_with_builder to ParseAndPrepareExport/Import/Revert. This lets you run these operations with a ServiceBuilder instead of a ServiceFactory.
      
      * Transition node and node-template to ServiceBuilder
      
      * Transition transaction-factory to the new service factory
      
      This is technically a breaking change, but the transaction-factory crate is only ever used from within substrate-node, which this commit updates as well.
      
      * Remove old service factory
      
      * Adjust the AbstractService trait to be more usable
      
      We slightly change the trait bounds in order to make all the methods usable.
      
      * Make substrate-service-test compile
      
      * Fix the node-cli tests
      
      * Remove the old API
      
      * Remove the components module
      
      * Fix indentation on chain_ops
      
      * Line widths
      
      * Fix bad line widths commit
      
      * Line widths again 🤦
      
      
      
      * Fix the sync test
      
      * Apply suggestions from code review

      srml/authority-discovery: Introduce srml module to sign and verify (#3385) · 495ccb60
      Max Inden authored
      In order to have authorities (validators) discover each other, they need
      to publish their public addresses by their ip address on the Kademlia
      Dht indexed by their public key. This payload needs to be signed by a
      key identifying them as a valid authority.
      
      Code inside `/core` does not know the current set of authorities nor
      can it assume what kind of cryptography primitives are currently in use.
      Instead it can retrieve its public key and the current set of
      authorities from the runtime and have it sign and verify Dht payloads.
      
      This commit enables code in `/core` to do so by introducing a srml
      module and runtime api to:
      
      1. Retrieve own public key.
      
      2. Retrieve public keys of current authority set.
      
      3. Sign a Dht payload.
      
      4. Verify a Dht payload.
      
      This commit makes the logic from the previous commit
      (`core/consensus/common/primitives.ConsensusApi`)
      444bf719 obsolete and thus removes it.
