61c569ab60refactor: decouple early return commands from AppInit (furszy)4927167f85gui: return EXIT_FAILURE on post-init fatal errors (furszy)3b2c61e819Return EXIT_FAILURE on post-init fatal errors (furszy)3c06926cf2refactor: index: use `AbortNode` in fatal error helper (Sebastian Falbesoner)9ddf7e03a3move ThreadImport ABC error to use AbortNode (furszy) Pull request description: It seems odd to return `EXIT_SUCCESS` when the node aborted execution due a fatal internal error or any post-init problem that triggers an unrequested shutdown. e.g. blocks or coins db I/O errors, disconnect block failure, failure during thread import (external blocks loading process error), among others.

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.
