At present, during init, we traverse the chain (once per index) to confirm that all necessary blocks to sync each index up to the current tip are present. To make the process more efficient, we can fetch the oldest block from the indexers and perform the chain data existence check from that point only once. This also moves the pruning violation check to the end of the 'loadinit' thread, which is where the reindex, block loading and chain activation processes happen. Making the node's startup process faster, allowing us to remove the global g_indexes_ready_to_sync flag, and enabling the execution of the pruning violation verification even when the reindex or reindex-chainstate flags are enabled (which has being skipped so far).
src/node/
The src/node/ directory contains code that needs to access node state
(state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar
classes).
Code in src/node/ is meant to be segregated from code in
src/wallet/ and src/qt/, to ensure wallet and GUI
code changes don't interfere with node operation, to allow wallet and GUI code
to run in separate processes, and to perhaps eventually allow wallet and GUI
code to be maintained in separate source repositories.
As a rule of thumb, code in one of the src/node/,
src/wallet/, or src/qt/ directories should avoid
calling code in the other directories directly, and only invoke it indirectly
through the more limited src/interfaces/ classes.
This directory is at the moment
sparsely populated. Eventually more substantial files like
src/validation.cpp and
src/txmempool.cpp might be moved there.
