Now that we track all announcers of an orphan, it's not helpful to consider an orphan provided by a peer that didn't send us this parent. It can only hurt our chances of finding the right orphan when there are multiple candidates. Adapt the 2 tests in p2p_opportunistic_1p1c.py that looked at 1p1c packages from different peers. Instead of checking that the right peer is punished, we now check that the package is not submitted. We can't use the functional test to see that the package was not considered because the behavior is indistinguishable (except for the logs).
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.
