765c0b364drefactor: combine Chain::findFirstBlockWithTime/findFirstBlockWithTimeAndHeight (Antoine Riard) Pull request description: As suggested in #14711, pass height to CChain::FindEarliestAtLeast to simplify Chain interface by combining findFirstBlockWithTime and findFirstBlockWithTimeAndHeight into one ACKs for commit 765c0b: jnewbery: utACK765c0b364d. Nice work @ariard! ryanofsky: utACK765c0b364d. Looks good, thanks for implementing the suggestion!

Internal c++ interfaces
The following interfaces are defined here:
-
Chain— used by wallet to access blockchain and mempool state. Added in #14437, #14711, #15288, and #10973. -
ChainClient— used by node to start & stopChainclients. Added in #14437. -
Node— used by GUI to start & stop bitcoin node. Added in #10244. -
Handler— returned byhandleEventmethods on interfaces above and used to manage lifetimes of event handlers. -
Init— used by multiprocess code to access interfaces above on startup. Added in #10102.
The interfaces above define boundaries between major components of bitcoin code (node, wallet, and gui), making it possible for them to run in different processes, and be tested, developed, and understood independently. These interfaces are not currently designed to be stable or to be used externally.
