DemiMarie-parity fb19684358 BABE signing and verification (#2270)
* Add basic BABE consensus type

* Update core/consensus/babe/slots/Cargo.toml

Co-Authored-By: DemiMarie-parity <48690212+DemiMarie-parity@users.noreply.github.com>

* Fix parameterization and run `rustfmt`

* Respond to review comments

* Update various Cargo.lock files

* Revert "Update various Cargo.lock files"

This reverts commit af53d7624752a744320e9cbb25749fdd8e6f46d2.

* `BabeSealSignature` → `BabeSeal`

* Move slot code to its own crate

This was highly non-trivial, due to cyclic dependencies.

* Remove redundancy between AuRa and BABE

Some of the code duplication was removed using a macro.

* Fix build error

* Avoid non-`#[doc(hidden)]` re-exports

Also, bump some library versions in `Cargo.toml`.

* Remove dead code in AuRa

* Remove impl_slot macro

It was more trouble than it was worth.

Also, delete useless dependencies on Serde.

* AuRa and BABE need different DB keys

* Bring back `aura::Network`, but deprecate it.

* Improve docs and add `slot_duration` inherent method

* Add docs to `substrate_consensus_aura::SlotDuration`

* Add missing documentation and #![forbid(missing_docs, unsafe_code)]

* Add a #![forbid(missing_docs)]

* Remove dependency of `test-runtime` on `slots`

* Update core/consensus/babe/src/lib.rs

* Remove wrongly added file

* Fix copyright notice

Co-Authored-By: DemiMarie-parity <48690212+DemiMarie-parity@users.noreply.github.com>

* Bump `impl_version` and `spec_version`

* Add more code to BABE

Most of it is copied from AuRa code, but at least the initial core is
there.

* Stuck on horrible compiler error message

* add missing files

* Spaces → tabs

* Simplify code

* Fix compilation

This involved fixing dependencies and adding a `Mutex`.

* More work on BABE

* Fix deprecation version

* Fix deprecation version; remove spurious carets

* Fix Cargo.toml

* Implement VRF signing logic

* The import queue code compiles, though it probably doesn’t work.

* Add VRF verification

* Update Cargo.lock

* Update dependencies

* Move test network to sr25519 authority keys

* Fix accidental build bustage

* Trying to get the tests to work

* Add logging messages and remove dead code

There seems to be a problem with the test network.  Since AuRa and BABE
are both affected, this is most likely due to the switch from ed25519 to
sr25519.

* Trying to get the tests to work

* Add logging messages and remove dead code

There seems to be a problem with the test network.  Since AuRa and BABE
are both affected, this is most likely due to the switch from ed25519 to
sr25519.

* Working testsuite at last!

The problem was with serialization and deserialization.  Normally,
those functions are generated automatically, but those for `BabeSeal`
had to be written manually.  The hand-written versions were not
correct, however, as shown by the decoder not being able to decode the
output of the encoder.

* Enable BabeSeal::Encode asserts in --release tests

* Bump runtime and dependency versions

* Fix wasm compilation

The wasm build was broken because of a typo in
`core/test-runtime/src/lib.rs`, and missing gates on the `std` feature
in `core/consensus/{aura,babe}/primitives/Cargo.toml`.  Additionally,
improve the quotation in the build scripts.

* Merge Cargo.lock

* Change expected JSON string

The test was also broken on `master`, so I suspect that the test was
incorrect.

* Responded to review

* Remove hard-coded threshold from production code

A hard-coded threshold is now only used in tests.

* Fix swapped doc comments

* Fix unused import warnings

* fix ci error

* fix typo

thiolliere d743a8b71f Implement parameterisable modules (#1800)
* first implementation

* remove done comment

* origin done

* impl log for instance

* impl inherent for instance

* Fix wasm build + full example build

this requires parity codec implements codec for core::marker::PhantomData

* patch parity-codec link to github branch

* improve internal names and fix instance prefix

* Fix in macros

* add test modules for support

this allow to test for construct_runtime as well.

The reason to have put that in another crate is:
* if we put test in `tests/` dir of srml/support then decl_storage fails to get
  srml-support access because it believes it is inside srml-support
  crate and so derive access to `quote!{ crate }` but this is wrong
  (and I don't see any way to prevent that, and it only bother us so I
  don't think that matters that much)
* if we put test inside lib.rs then contruct_runtime cannot be used
  because it call some macros that are defined with macros
  (decl_outer_event and decl_outer_origin) and thus rustc complains.

* defaultinstance to its own struct to avoid errors

* enforce <T, I> for Event and Config, impl test

* add origin, log, inherent to test

* test more code generation

* basic storage test

* fix typo

* rename a few imports and field

* delete wip test in example and runtime

* change default prefix to make it backward compatible with test

* rename Instance to I and Instantiable to Instance

note: the name of generic parameter I is only enforce by decl_module!
and this could be rewritten

Bastian Köcher 190393d476 Make API backwards compatible with CC (#1697)
* Rework how a runtime api calls into the runtime

Now we generate a default implementation for each api call that calls
a generated method `method_runtime_api_impl`. This newly generated
method is the one that will be implemented by the `impl_runtime_apis`
macro in the runtime for the client side.
