      Introduce flag to enable sentry nodes to participate in grandpa gossip · 850455f8
      Max Inden authored 
      Given the following situation: A validator 'A' is not supposed to be
connected to the public internet to protect it from e.g. a DoS attack.
Instead it connects to a sentry node 'sentry-A' which connects to the
public internet. Validator 'B' can reach validator 'A' via sentry node
'sentry-A' and vice versa.

A sentry node needs to participate in the grandpa gossip without
becoming a validator itself in order to forward these message to its
validator. This commit adds a new command line flag (`--grandpa-voter`)
forcing a node to participate in the grandpa voting process even though
no `--key` was specified. Due to the fact that it does not have a key,
it does not become a validator in the network.

In order to simulate the above situation this commit also adds a Docker
Compose file (`scripts/sentry-node/docker-compose.yml`) with further
documentation.

      Fix peer discovery delays. (#2982) · e63598b6
      Roman Borschel authored 
      * 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.

      Relative slots (#2820) · 2d7b4fe8
      DemiMarie-parity authored 
      

* Initial work on relative slots for BABE

* More work

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

`Aura` → `Babe`

Co-Authored-By: default avatarPierre Krieger <[email protected]>

* More work on relative slots

* Add missing field in test-runtime

* Bump `impl_version` and `authoring_version`

* Fix compile errors and warnings

* Upgrade dependencies

* Update dependencies more

* Revert some updates to dependencies

Somehow, those broke the build

* Fix compilation errors

* `Duration` → `u128` in calculations

* `slot_duration` is in milleseconds, not seconds

* Median algorithm: ignore blocks with slot_num < sl

* Fix silly compile error

* Store a duration, rather than an instant

It is more useful

* Fix compilation errors

* `INVERSE_NANO` → `NANOS_PER_SEC`

Also: `1000_000_000` → `1_000_000_000`

Suggested-by: default avatarNiklas Adolfsson <[email protected]>

* Un-bump `authoring_version`

* Disable median algorithm when `median_required_blocks` is 0

Otherwise it would panic.

* Apply suggestions from code review

Co-Authored-By: default avatarBastian Köcher <[email protected]>

* Simplify panic

* Fix build error

* Create `SignedDuration` struct

for signed `Duration` values.

Suggested-by: Bastian Köcher

* Refactor median algorithm into separate function

* Add issues for FIXMEs and respond to code review

* Fix minor warnings
