* Initial work on exposing pre-runtime digests
This provides the primitive API, as well as exposing it from BABE.
* Initial work on using pre-digests in runtimes
This includes both code to expose them from `srml_system`, as well as
using it in (currently dead) code in `srml_babe`.
* Bump `{spec,impl}_version`
* Add `u64_backend` feature to curve25519-dalek
Otherwise, it errors out at compile-time.
* Bump `Cargo.lock`
* Do not depend on the schnorrkel crate in the runtime
The schnorrkel crate does not work on `#![no_std]`, but the runtime only
needs constants from it. This adds our own definitions of those
constants, and checks them for correctness at compile-time.
* Actually implement storage of VRF outputs
* Trivial formatting change
* Provide a `hash_randomness` function in BABE
for processing VRF outputs.
* Implement a basic randomness generating function
It just XORs the VRF outputs together.
* Actually implement on-chain randomness
Blake2b is used for hashing.
* Update dependencies
* Run `cargo update` where needed
* Re-add a newline at EOF
* Remove broken and unsafe code
XOR is not a hash function, and must not be used as such. The
implementation was also needlessly unsafe.
* Run `cargo update` where needed
* Remove spurious dependency
* Document security guarantees of BABE randomness
* Add a `RandomnessBeacon` trait
* Document `RandomnessBeacon::random`
* Fix silly compile error (unexpected type arguments)
* Fix BABE randomness
* Implement `FindAuthor` for `babe::Module`
* Apply suggestions from code review

* Respond to suggestions from code review and fix bugs
* Store an authority index, not the authority itself.
* Avoid unnecessary decoding.
* Implement relative slots and BABE randomness fully and correctly.
* Remove spurious dependency
* Fix error reported by rust-analyzer
* Update Cargo.lock files
* `wrapping_add` → `checked_add`
The epoch index will not overflow. Panic if it does.
* Move randomness documentation to trait
* Fix compile error in test suite
* Explain 2^64 limit

* Add claims prefix to the genesis configuration
* Claims module not included in runtime yet
So we don't need to set any genesis config yet
* Use Param rather than Storage
* Fix DiscoveryBehaviour::poll.
The previous implementation regularly returned `NotReady` from `poll`
despite the inner Kademlia behaviour having events ready, thus letting
the `poll`ing be largely driven by the task wakeups from the Delay for
the next random Kademlia query, inducing major delays in consuming
the ready Kademlia events and thus slowing progress.
The discovery test now passes quickly, as expected.
* Ensure the Delay is polled right after reset.
For task wakeup.
* Some cleanup
* Add module constant metadata declaration
* Begin to integrate the constants in `decl_module`
* Fixes tests
* Fix compilation and add tests
* Remove duplicate code
* Expose constants in democracy and staking + further fixes
* Update srml/metadata/src/lib.rs

* Hide `RawEvent` metadata function
* Prevent whitespaces in types
* Fix `offchain_worker` and `constants` with instances
* Up the `impl_version`
* Fix macro
* Incrase impl_version
This macro compiles and executes the given code only when `std` feature
is enabled. This can be useful for debugging without needing to worry
that your code does not compile on `no_std`.
* Introduce `BuildParachainContext` trait
* Change the structure and hide the actual network implementation behind a
trait
* Add functions to collator `Network` trait
* Remove dependencies on tokio
* Make service not depend on tokio
* Fix service tests
* Manually poll the import queue if failed to start
* Spawn all tasks at the end
* Remove executor from TelemetryOnConnect
* Remove TaskExecutor from offchain workers
* Remove TaskExecutor from AuthoritySetup
* Remove TaskExecutor from service
* Remove tokio dependency from RPC
* Remove finality-grandpa from WASM checks
* Fix offchain tests
* Line widths
* Fix RPC tests
* Fix service tests
* Fix bad futures polling
* Address some concerns
* Better error handling
* Is it the connectivity test that's not passing? I don't know, let's try
* Revert "Is it the connectivity test that's not passing? I don't know, let's try"
This reverts commit 28bbe51f0e2e4885fe1f901e11078604604cb212.
* Fix test
* check resulting state root on import.
* get root from last method.
* Fix test runtime (was changing state after root calculation).
* Do reset new authorities (just take before root calculation).
* bump impl runtime version.
* Update core/sr-api-macros/tests/trybuild.rs

* srml-contract: Move gas costs from Config to Schedule.
* srml-contract: Define Gas units fixed as u64.
This removes Gas as a configurable type on the contracts Trait.
* Bump node runtime spec/impl versions.
* generalized uncle processing
* add some uncle tests
* set author and do event handling
* OnePerAuthorPerHeight no longer O(n^2) and test
* bump impl_version of node
* Documentation and style fixes

* fix#2949: index-based FindAuthor wrapper for srml-session
* use for_each_tuple
* Make `polkadot-parachain` call `validate_block` instead of `validate`
Also switch to rust 2018 in the crate
* Use `rstd`
* Make `load_params` a pointer
* Test for not dispatching calls if top level execution fails
* Add comment to test
* Only dispatch calls if contract execution succeeded
Note that `calls` should be empty in this case, but this makes things
clearer
* Add comment to test
