Pierre Krieger efe32f370a Minor tweak to requirements of AbstractService (#3493) 2019-08-27 15:07:26 +02:00
Pierre Krieger 5b8ebf7baf Service factory refactor (#3382)
* 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

Max Inden 2c0e73b78c srml/authority-discovery: Introduce srml module to sign and verify (#3385)
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`)
cf80af9255 obsolete and thus removes it.

* Replace ValidatorIdByIndex with CurrentElectedSet

ValidatorIdByIndex was querying the current_elected set in each call, doing loading (even though its from cache), deserializing and cloning of element.

Instead of this it is more efficient to use `CurrentElectedSet`. As a small bonus, the invariant became a little bit easier: now we just rely on the fact that `keys` and `current_elected` set are of the same length rather than relying on the fact that `validator_id_by_index` would work similar to `<[T]>::get`.
