Both waitTipChanged() and createNewBlock() can take a long time to return. Add a way for clients to interrupt them. The new m_interrupt_mining is safely accessed with a lock on m_tip_block_mutex, but it has no guard annotation. A more thorough solution is discussed here: https://github.com/bitcoin/bitcoin/pull/34184#discussion_r2743566474
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 #19160. -
Ipc— used by multiprocess code to accessInitinterface across processes. Added in #19160.
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.
