I reviewed the code again (didn't look that deep into the test changes), and did some manual testing.

Pretty sure it's unrelated, same thing just happened on master: https://github.com/bitcoin/bitcoin/runs/14733904119 (some discussion in #27988)

Now `ChainstateManager` has `ActiveSnapshotBase()` and `GetSnapshotBaseBlock()` which, as far as I understand it, do the same thing except for the caching.
Would it have been possible to add the caching to the existing `GetSnapshotBaseBlock()` instead?

I don't understand why you're ignoring an approach that seems to do a better job of getting what you want (instant channels, without even having to wait a minute), and can work on mainnet (so won't end up developing a UX that's only conceivably good for demos and doesn't work with real money), and is already supported by CLN, LND and LDK. If you don't want to explain, or even just figure "if it's dumb but it works that's good eno

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.

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.

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

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.

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.

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
