Currently it is an alias to the global ::mempool and should be used as follows. * Node code (validation and transaction relay) can use either ::mempool or node.mempool, whichever seems a better fit. * RPC code should use the added convenience getter EnsureMempool, which makes sure the mempool exists before use. This prepares the RPC code to a future where the mempool might be disabled at runtime or compile time. * Test code should use m_node.mempool directly, as the mempool is always initialized for tests.
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.
The src/node/ directory is a new directory introduced in
#14978 and at the moment is
sparsely populated. Eventually more substantial files like
src/validation.cpp and
src/txmempool.cpp might be moved there.
