test: add test that EvictTxPeerIfFull only evicts tx-relaying peers

This commit only adds a new automated test to Bitcoin Core. It checks that when the node is full of block-only peers (peers that do not relay transactions), an incoming connection is rejected rather than incorrectly kicking out a block-onl…

test: wallet: BnB incomplete result on attempt-limit success

This commit adds a new unit test for Bitcoin Core's coin selection algorithm. It checks that when the Branch-and-Bound (BnB) search finds a usable coin selection early but then keeps searching for a better one until it hits the attempt lim…

This commit only adds a new automated test to Bitcoin Core. It verifies that when a node connects to a 'private broadcast' peer which signals it does not relay transactions (relay=false), the node disconnects that peer. There is no change …

addrman: remove unreachable tried-collision branch

This commit removes a fallback code path in Bitcoin Core's address manager that the authors say can never be reached under current rules. It replaces that fallback with internal consistency checks (assertions). The change is a code-cleanup…

test: announce field must be 0 or 1 in sendcmpct

net_processing: fix BIP152 first integer interpretation

This change tightens how Bitcoin Core handles a compact-blocks handshake message. The old code read a small number from the network and treated any non-zero value as 'true'; the new code rejects values other than 0 or 1. This prevents a pe…
