rABC799f65f976aa: [avalanche] Add wrappers to add and remove a proof from a proof pool
Summary

This will make it easier to use the ProofPool structure to store the orphans. It makes the ProofPool a class, but the internal container is kept public to avoid bloating the diff with more changes. Accessors can be added as needed later to make it private. There is no change in behavior.

Ref T1854.

Depends on D10582.

Test Plan
ninja all check-all

Is it something we want at all now that we don't want to store the orphan in the proof pool? Also, it seems like you are slowly recreating fetchOrCreatePeer with extra steps.

This whole contraption doesn't make a lot of sense does it? state is passed down, but it's useless, because it is captured by the lambda. I assume you wanted WITH_LOCK

264 ↗(On Diff #30987)

You really want to check if this thing is in the pool. If it already is, then addToPool will remove it.

291 ↗(On Diff #30987)

I you pass a reference from a proof that is itself within the proof pool, you might destroy it before this function terminates. It's probably best to take by value - and add a comment about this.

I was wondering WTF was going on there, until I read was isValid does. Needless to say, it doesn't check the validity of the proof id.

Move this into createPeer.

Check if the proof is present in the pool, return a tristate: already present, added and conflicted. Make conflicted 0 so that it is falsy.

301 ↗(On Diff #30987)

Do the call addToPool here. If it is added, you failed to add, or it was already present, return.

Make the ProofPool a struct, and replace addToPool/removeFromPool with addProof/removeProof methods.
This removes the need for passing the ProofPool as a parameter, and makes the API cleaner.

I don't know if there is a more idiomatic way of doing a tristate in c++ (without pulling boost::tribool). I started with std::optional<bool> but this makes the code very confusing due to the implicit bool conversion provided by std::optional, so I went the naive and verbose way.

This if cascade calls for a switch. With no default, it'll warn on missing enums cases.

You probably want to assert the proof is not null here.

Use a switch on the AddProofStatus, and assert the proof is not nullptr in addProof()

Invert the proofs sequences in the test. This has no impact on the test actually but will later make it obvious that the behavior changed in D10524.

break ? And why braces?

We have a mix of braces/no braces in the codebase. It seems that braces are added to the most recent code, but it's not consistent.
