>Request the starting hash with GET /rest/blockhashbyheight/<HEIGHT>.<bin|hex|json> and then request headers upward with /rest/headers/?

We currently use this approach at L2L. This strategy is far from ideal - any of the upward requests may return headers from a different active chain, in the event of a re-org. It is necessary to check that the final block hash is the same as the tip hash we want to sync to, and if it is not, then the only way to retrieve the headers would be requesting heade

📝 ryanofsky opened a pull request: "init: Require explicit -asmap filename"
(https://github.com/bitcoin/bitcoin/pull/33770)
Currently, if `-asmap` is specified without a filename bitcoind tries to load `ip_asn.map` data file.

This change now requires `-asmap=ip_asn.map` or another filename to be specified explicitly.

The change is intended to make behavior of the option explicit avoid confusion reported https://github.com/bitcoin/bitcoin/issues/33386 where documentation specifies a default file which is not actually loaded by default. It was originally implemented in

Hmm right I was not clearing the containers, so the sorting was dominating. I retried with clearing and the unordered_map is still slightly faster. In your benchmark you are creating and reserving the map inside the benchmark instead of before. In this implementation the reserved memory is kept in between blocks, so reserving and creating outside makes more sense.

Why would short ids matter here though? Isn't that for keeping the bandwidth smaller for compact blocks?

> The long term plan is to have the embedded data used by default, however first the idea was to have a release or two with the data embedded but the usage still off by default.

This makes sense, but I think if it is the plan, it should rule out option "1. Use the default file when it's present" so `bitcoind` will consistently just not load asmap data, instead of loading a file by default but not loading embedded data by

no, I mean, we don't actually need 256 bits of precision here, just a probabilitistic check, so taking the first 32/64 bits of the hash should suffice, since the worst case is just going to disk, so it's not a tragedy if there are false positives, as long as in the average case checks are lot faster

Concept ACK on improving the documentation, but there is room for improvement on the specific phrasing.

This comment is unhelpful. It provides the information that is already available from the code, but does not correctly explain the abstract context.

* @param[in] change_fee The cost of adding the change output to the transaction at the transaction’s feerate. Budgeting separately ensures that the change’s amount will be at least CHANGE_LOWER.

SRD does _NOT_ minimize the number of UTXOs included in the result. It only ensures that the selection adheres to the weight limit. *Minimizing* would imply that the selection is further pruned beyond adhering to the weight limit. The last sentence should also be amended to clarify that SRD does not always return a result, but when it does, the selection will always create a change output:

📝 purpleKarrot opened a pull request: "refactor: C++20 operators"
(https://github.com/bitcoin/bitcoin/pull/33771)
Remove all `operator!=` definitions and provide `operator<=>` as a replacement where all relational comparison operators were defined before.

The compiler is able to deduce missing comparison operators from `operator!=` and `operator<=>`. The compiler provided operators have the following advantages:

1. less code
2. guaranteed consistency

Refactoring that changes the implementation, or replaces it with `= default` is left for a separate PR.

nit: Named variable feels clearer. (No risk of confusing with the index used for `block.vtx[...]`).

Thanks for using separate peers in 42e281dba0f0807cc08d8c50a9d19906e27e2129. Was totally not expecting the reassignment of `segwit_node`. :sleeping:

I like how you use `hb_peer_idx` in f24237ef3d8c94c01f4b9f86a7d28d0b5fcdc75b as both a parameter for `assert_highbandwidth_states()` and for indexing into `self.nodes[0].p2ps`.
