rABCdf673a6df8aa: [seeder] Mark nodes as unreliable until checkpoint verified
Summary

This improves on D16465 by waiting for the response to GETHEADERS before considering a node to be reliable.
The GETADDR and GETHEADERS logic is reworked so that the messages are now send independantly of each other (GETADDR is only sent once a day for each node). There is still an issue caused by the fact that if the ADDR message arrives the node is done, and as such it can miss out on the HEADERS and incorrectly mark nodes as bad. This issue is fixed in a separate diff.

Upon first start of a seeder after this commit, all nodes from the existing are considered to have a verified checkpoint (until proven otherwise). This is to avoid clearing the entire db immediately and then have to repopulate it.

This is a partial backport of bchn#1820

Depends on D16499

Test Plan

run the seeder before and after this change, confirm that we eventually get only Bitcoin ABC nodes (after waiting for long enough)

ninja bitcoin-seeder check-seeder
src/seeder/bitcoin-seeder -dumpinterval=60

After a very long time:

awk '{ if ($2 == 1) { print } }' dnsseed.dump

I think this is not accurate, you also need to check the height of the last checkpoint is > 0.
I don't think the nodes will send the genesis header, so if you think regtest where the only checkpoint is the genesis block this would not work.

OK for the additional checkpoint height test. I was thinking more about the first couple of weeks after we start a new testnet (before it gets a checkpoint), or maybe Signet if we ever backport it.

PiRK updated this revision to Diff 50110.Oct 15 2024, 14:16

check last checkpoint height to decide whether checkpoints should be validated
This requires a unit test to now use the MainNet params.
