Toralf Wittner dc41558b6e Change network::sync::extra_requests to not send. (#2890)
* Change network::sync::extra_requests to not send.

Instead it only maintains the invariants and leaves the actual I/O part
to the parent module (i.e. `sync`).

* Update Cargo.lock.

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

* Fix spacing in docs

* Minor changes suggested by @joepetrowski

on https://github.com/paritytech/substrate/pull/2372

* Remove unnecessary getters

* fix compile error

* Fix silly unused-variable error

* Improve documentation formatting

DemiMarie-parity a10e86ba5a Refactor DigestItem (#2108)
* Add `start_aura2`.

* .gitignore patch conflict files

and remove one that accidentally got committed

* Fix build

The tests still don’t work.

* Fix compilation errors

* Fix compile errors (again)

* Try (and fail) to fix tests

* Properly deserialize data

Previously, `DigestItem::Consensus` had no separate `DigestItemType`,
so it did not get properly serialized and deserialized.

* Add extra debug logging.  Always allow old seals.

A `RUST_LOG=substrate_aura_consensus cargo test --all -- --nocapture \
tests::authoring_blocks` revealed that old seals were being and
rejected, causing the test to hang.  As a temporary debug measure, allow
old seals unconditionally, so that CI can test if this fixes the
problem.

* Forcibly disable rejection of old seals

* Use old trait, but newer serialization

The old trait for `CompatibleDigestItem` actually worked.  By changing
its implementation, one can ensure that all *new* seals have the modern
form, but *legacy* seals are still decoded correctly.

* Bump impl version

* Squash spurious deprecation warning

`rustc` should not be emitting a deprecation warning in deprecated
code, but it does, so silence it.

* Rip out unused Cargo feature

* Move AURA to aura_primitives

* Respond to code review

* Wrap overly-long line

* Reduce logging verbosity and add target

* Add dependency on `sr-primitives` to `aura_primitives`

* Fix build

It failed with a message about Cargo.lock being out of date.

* core: aura: rename aura engine id const

* core: aura: remove superfluous logging

* core: primitives: add removed semicolons

* core: aura: remove unused import

* core: network: style fix

* runtime: update wasm blobs

* runtime: bump impl_version
