      Introduce new concept of "slot portion for proposing" (#8280) · 7599e0d6
      Bastian Köcher authored 
      * Introduce new concept of "slot portion for proposing"

Currently when building a block we actually give the proposer all of the
time in the slot, while this is wrong. The slot is actually split in at
least two phases proposing and propagation or in the polkadot case into
three phases validating pov's, proposing and propagation. As we don't
want to bring that much polkadot concepts into Substrate, we only
support splitting the slot into proposing and propagation. The portion
can now be passed as parameter to AuRa and BABE to configure this value.
However, this slot portion for propagation doesn't mean that the
proposer can not go over this limit. When we miss slots we still apply
the lenience factor to increase the proposing time, so that we have
enough time to build a heavy block.

Besides all what was said above, this is especially required for
parachains. Parachains have a much more constraint proposing window.
Currently the slot duration is at minimum 12 seconds, but we only have
around 500ms for proposing. So, this slot portion for proposing is
really required to make it working without hacks.

      AuRa improvements (#8255) · 1680422f
      Bastian Köcher authored 
      

* AuRa improvements

Hot and fresh AuRa improvements. This pr does the following:

- Move code belonging to the import queue etc to import_queue.rs
- Introduce `ImportQueueParams` and `StartAuraParams` structs to make
it more easier to understand what parameters we pass to AuRa.
- Introduce `CheckForEquivocation` to tell AuRa if it should check for
equivocation on block import. This is required for parachains, because
they are allowed to equivocate when they build two blocks for the same
slot, but for different relay chain parents.

* Update client/consensus/aura/src/import_queue.rs

      * Ensure we spawn the block import worker as an essential task

This pr ensures that we spawn the block import worker as an essential
task. This is quite important as we need to bring down the node when the
block import is done. Besides that it adds some debug output to the
block import worker.

      Introduce a `Slot` type (#7997) · b6294418
      Bastian Köcher authored 
      

* Introduce a `Slot` type

Instead of having some type definition that only was used in half of the
code or directly using `u64`, this adds a new unit type wrapper `Slot`.
This makes it especially easy for the outside api to know what type is
expected/returned.

* Change epoch duratioC

* rename all instances of slot number to slot

* Make the constructor private

      Skip slot lenience on first block in BABE (#7515) · 48a84f90
      Bastian Köcher authored 
      The genesis header doesn't have the BABE pre-digest and we insert `0` as
slot number. The slot lenience calculation will return the maximum in
this situation. Besides returning the maximum which is not bad at all,
it also prints some a debug message that can be confusing in the first
moment. To prevent printing this debug message, we now just return early
when we see that the parent block is the genesis block.
