      Request backed candidates unbounded. (#5610) · 72723c8a
      Robert Klotzner authored 
      We are awaiting on the oneshot anyways, so we have back pressure. By
using the unbounded channel make log messages like the following less
likely (due to higher priority):

      Add staging runtime api (#5048) · fd020c07
      Tsvetomir Dimitrov authored 
      * Move `trait ParachainHost` to a separate version independent module

`trait ParachainHost` is no longer part of a specific primitives
version. Instead there is a single trait for stable and staging api
versions. The trait contains stable AND staging methods. The latter are
explicitly marked as unstable.

* Fix `use` primitives

`polkadot_primitives::v2` becomes `polkadot_primitives::runtime_api`

* Staging API declaration and stubs

Introduces the concept for 'staging functions' in runtime API. These
functions are still in testing and they are meant to be used only
within test networks (Westend).
They coexist with the stable calls for technical reasons - maintaining
different runtime APIs for different networks is hard to implement.

Check the doc comments in source files for more details how the staging
API should be used.

* Add new staging method - get_session_disputes()

Add `staging_get_session_disputes` to `ParachainHost` as the first
method of the staging API.

* Hide vstaging runtime api implementations  behind feature flag

* Fix test runtime

* fn staging_get_session_disputes() is renamed to fn staging_get_disputes()

      Fixes the dead lock when any of the channels get at capacity. (#5297) · b89dc00e
      Sergei Shulepov authored 
      The PVF host is designed to avoid spawning tasks to minimize knowledge
of outer code. Using `async_std::task::spawn` (or Tokio's counterpart)
deemed unacceptable, `SpawnNamed` undesirable. Instead there is only one
task returned that is spawned by the candidate-validation subsystem.
The tasks from the sub-components are polled by that root task.

However, the way the tasks are bundled was incorrect. There was a giant
select that was polling those tasks. Particularly, that implies that as soon as
one of the arms of that select goes into await those sub-tasks stop
getting polled. This is a recipe for a deadlock which indeed happened
here.

Specifically, the deadlock happened during sending messages to the
execute queue by calling
[`send_execute`](https://github.com/paritytech/polkadot/blob/a68d9be35656dcd96e378fd9dd3d613af754d48a/node/core/pvf/src/host.rs#L601).
When the channel to the queue reaches the capacity, the control flow is
suspended until the queue handles those messages. Since this code is
essentially reached from [one of the select
arms](https://github.com/paritytech/polkadot/blob/a68d9be35656dcd96e378fd9dd3d613af754d48a/node/core/pvf/src/host.rs#L371),
the queue won't be given the control and thus no further progress can be
made.

This problem is solved by bundling the tasks one level higher instead,
by `selecting` over those long-running tasks.

We also stop treating returning from those long-running tasks as error
conditions, since that can happen during legit shutdown.
