rABC4f410b8b7e06: [avalanche] Reject transactions that conflict with a finalized one

Summary

Treat these transaction separately from "regular" conflicting transactions, because they are plain invalid and don't need to be stored in the conflict pool.

After this diff we have 2 kind of conflicting txs:

conflicting with a non finalized transaction: at this stage the node has no idea which transaction is legit and it needs to be reconciled via avalanche (in a later diff)
conflicting with a finalized transaction: at this stage the node knows that this transaction is not the selected one and it should be treated as invalid.

The avalanche reconsiderable status could be later used to vote on transactions for other reason, e.g. for transactions that spend a proof coin.

Depends on D16649.

49 ↗	(On Diff #49232)	what else could this include in addition to txs conflicting with another mempool tx?

Fabien added inline comments.Thu, Aug 15, 18:36

src/consensus/validation.h
49 ↗	(On Diff #49232)	For now nothing else but we can imagine fees for example, or deployment of some new features with no consensus change (not planning to do so but imagine enforcing schnorr signatures only for example)

Fabien added inline comments.Thu, Aug 15, 18:45

src/consensus/validation.h
49 ↗	(On Diff #49232)	Oh and also reject the txs that spend coins from an avalanche proof

bytesofman added inline comments.Thu, Aug 15, 22:25

src/consensus/validation.h
49 ↗	(On Diff #49232)	would this be the sort of thing that could be appropriate to include in comments? seems like there is no way for a developer without your individual insight here to know what this bucket would be, at least not without consulting this diff

roqqit added inline comments.

src/consensus/validation.h
49 ↗	(On Diff #49232)	I think the right way to do this is document these examples in the summary so they will appear as part of the commit. No need to include speculative features in code/comments. Relatedly, the distinction in the summary between "regular" conflicts, plain invalid, and policy failures (maybe reconsiderable?) is not clear. It would help to describe the interplay between TX_CONFLICT and TX_AVALANCHE_RECONSIDERABLE

Fix a typo and update the summary to better explain the rationale

Rebase and rename gettransactionpool -> gettransactionstatus

Harbormaster completed remote builds in B30010: Diff 49254.Fri, Aug 16, 10:51

Looks good.
As discussed above, there is some ambiguity about TX_AVALANCHE_RECONSIDERABLE currently only being used for non-finalized conflicting txs (tx added to the TxConflicting pool). The pool will need to be renamed if/when we start adding other type of transactions to it, but that can be done if/when needed.
