👍 ryanofsky approved a pull request: "Rework validation logic for assumeutxo"
(https://github.com/bitcoin/bitcoin/pull/27746#pullrequestreview-1505486978)
Partial code review ACK 03dfe04075668aa3b99a5d6d68adfcecffca0593. I've looked in detail at almost all of this except for tests. It seems like a big improvement and I haven't found any real issues at all. Am planning to review more soon.

In commit "Move block-arrival information / preciousblock counters to ChainstateManager" (0dbc5805ca4371b7621bee0b7a553dac1a481614)

IIUC removing this line is not a change in behavior because the `nBlockSequenceId` variable was never used again after the `UnloadBlockIndex` call, outside of tests. Now there is new `ResetBlockSequenceCounters` function that tests can use to reset it separately. EDIT: Another review comment https://github.com/bitcoin/bitcoin/pull/27746#discussion_r1243705025 als

It would be nice to have a documentation comment for this function saying what it is for, especially since it is only called in a test. If the counter values are basically arbitrary and only used for ordering, I'm not sure why if they actually ever need to be reset, or if that's just a nice thing to do?

In commit "test: Clear block index flags when testing snapshots" (e8168cd56c490609f59e1dc89add58b1be18b516)

This seems like a good change that makes test setup more realistic, but the could the commit message be updated to say what is motivating this change? Is it just for realism, or will a future change, or a certain kind of test depend on it?

The test seems to pass without this line, at least in this commit.

If this is needed for a future change, would be good to say that in commit message. Or if this is just done for completeness would be good to say that in a code comment.

In commit "test: Clear block index flags when testing snapshots" (e8168cd56c490609f59e1dc89add58b1be18b516)

Adding `BLOCK_ASSUMED_VALID` here seems surprising since I would expect `ActivateSnapshot` below to be setting `BLOCK_ASSUMED_VALID`, and comment above doesn't mention this flag. I think it would be good to drop this line or add a comment explaining why it is necessary.

In commit "Move block-storage-related logic to ChainstateManager" (034f920d1755cff752d46b089ad37bdd703bf896)

Note: This change to the `CheckBlockIndex()` call is temporary and will revert back in later commit fb9c405506d6cfb6896e21b79789d7b6e638f6f2 "Move CheckBlockIndex() from Chainstate to ChainstateManager" when it becomes a `ChainstateManager` method.

In commit "Fix initialization of setBlockIndexCandidates when working with multiple chainstates" (c2bc5cfd9977838af334844675d77090fe9c3c74)

Can add a comment here explaining the logic? I guess the `pindex == GetSnapshotBaseBlock()` case needs to be a special case because the snapshot block may not have transactions?

Maybe also would be more efficient to call `ActiveSnapshotBase` instead of `GetSnapshotBaseBlock` here. I think I would move the commit introducing the `ActiveSnapshotBase` met

In commit "Move block-storage-related logic to ChainstateManager" (034f920d1755cff752d46b089ad37bdd703bf896)

Notes: It seems logical to call `GetAll` for all chainstates and let the `TryAddBlockIndexCandidate` and `FindMostWorkChain` functions figure out how to use the block and which chain to attach it to.

There is a change in behavior here if there are multiple chainstates, because previously this would only add blocks to `setBlockIndexCandidates` for the active chain, and now it will ad

Do you think it would be good if the `IsInitialBlockDownload` method were moved to `ChainstateManager`. Is there any place it should be actually called on the background chainstate rather than the active chainstate? Could add a TODO comment if IsInitialBlockDownload method should move like other methods are moving.

The wallet that I am working on supports and uses 0-conf channels. That doesn't negate the fact that shorter block times are useful.

> Reading through recent comments, it seems somewhat expected that this version isn't yet fully working, let me know when you want me to run my tests again!

Sorry about that, I was a bit in a rush on Friday. I’ve fixed a number of issues, if this latest push’s checks turn up green, it might be more fruitful to try now.

> Yeah, should be caused by an upstream CI change. I guess there should be no risk in changing 120s to 300s, even potentially fixing the issue you see.

Saw it on master now too: https://github.com/bitcoin/bitcoin/runs/14733904119

I think the reason why this didn't fail before is that the `coinstatsindex_unclean_shutdown` used `GetTime` / `NodeClock` instead of `SteadyClock` before this PR. So since mocktime was used (which doesn't change after the 100 blocks are mined), the timeout was

The tests objective is to exercise the chain synchronization code,
verifying that the indexes are able to catch up with the chain-tip.
Therefore, there is no need to run the process on a worker thread.

Important Note:
After #27607, the `BaseIndex::Start` method will be almost empty.

It was somewhat surprising to me that wallet_backwards_compatibility.py did not catch #27915 since the purpose of the test is to find downgrade issues such as that. It turns out the test was deficient in several places when it came to testing descriptor wallets, as well as deficient in addition to failing to correctly test some releases.

This PR fixes these test cases, adds more informative logging, slightly refactors the entire test in order to better test future versions, and adds a 25.0 no
