The previous help message was pretty generic as it covered two potential
error scenarios. This change gives a more detailed error message to each
of those errors.
`Arc` is already a reference internally, so it does not seem to be
beneficial to pass a reference to it. Just adds an extra layer of
indirection.
Functions that need to be able to increment `Arc` reference count need
to take `Arc<AtomicBool>`, but those that just want to read the
`AtomicBool` value can accept `&AtomicBool`, making them a bit more
generic.
This change focuses specifically on `Arc<AtomicBool>`. There are other
uses of `&Arc<T>` in the code base that could be converted in a similar
manner. But it would make the change even larger.
This function has morphed as it has been updated, and the existing
function name is a bit of misnomer. Update the function name to use
terminology that I think is more clear and more consistent with what we
use core/src/validator.rs. Additionally, adjust the error messages to be
more clear about what exactly is wrong for when we can't process.
The callstack updated in this PR passed an &Arc<...> down only to have
the bottom level clone the reference. Thus, we are giving shared
ownership so the reference is a bit redundant and arguably obscures the
intention to clone further down the callstack.
* Move entry_notifier_interface
* Add EntryNotifierService
* Use descriptive struct in sender/receiver
* Optionally initialize EntryNotifierService in validator
* Plumb EntryNotfierSender into Tvu, blockstore_processor
* Plumb EntryNotfierSender into Tpu
* Only return one option when constructing EntryNotifierService
