      Replace async-std with tokio in PVF subsystem (#6419) · 44fd9566
      Marcin S. authored 
      

* Replace async-std with tokio in PVF subsystem

* Rework workers to use `select!` instead of a mutex

The improvement in code readability is more important than the thread overhead.

* Remove unnecessary `fuse`

* Add explanation for `expect()`

* Update node/core/pvf/src/worker_common.rs

Co-authored-by: default avatarBastian Köcher <[email protected]>

* Address some review comments

* Shutdown tokio runtime

* Run cargo fmt

* Add a small note about retries

* Fix up merge

* Rework `cpu_time_monitor_loop` to return when other thread finishes

* Add error string to PrepareError::IoErr variant

* Log when artifacts fail to prepare

* Fix `cpu_time_monitor_loop`; fix test

* Fix text

* Fix a couple of potential minor data races.

First data race was due to logging in the CPU monitor thread even if the
job (other thread) finished. It can technically finish before or after the log.

Maybe best would be to move this log to the `select!`s, where we are guaranteed
to have chosen the timed-out branch, although there would be a bit of
duplication.

Also, it was possible for this thread to complete before we executed
`finished_tx.send` in the other thread, which would trigger an error as the
receiver has already been dropped. And right now, such a spurious error from
`send` would be returned even if the job otherwise succeeded.

* Update Cargo.lock

+ Adds some more granularity to the prepare errors.
+ Better distinguish whether errors occur on the host side or the worker.
+ Do not kill the worker if the error happened on the host side.

+ Removes unnecessary indirection with `Selected` type.

* Add missing docs, resolve TODOs

* Address review comments and remove TODOs

* Fix error in CI
