validation: check invariants when inserting into m_blocks_unlinked

This commit adds safety checks around a Bitcoin Core internal data structure called m_blocks_unlinked, which tracks blocks whose parent chain is missing. The change prevents two problems: inserting blocks that have no actual stored data, a…

test/doc: remove misleading comment and improve tests

validation: avoid duplicates in m_blocks_unlinked

This Bitcoin Core update fixes a bug where, during a deep chain reorganization on a pruned node, the same block entries could accidentally be added twice to an internal waiting list. If processed twice later, this could corrupt an ordered …

This commit only changes a test file. It adjusts which block height is invalidated in an existing functional test so that the test exercises a specific edge case involving duplicate block processing in pruned nodes. There is no change to p…

refactor: use for loops in FindMostWorkChain

This commit is a straightforward code cleanup in Bitcoin Core. It rewrites two while loops as for loops in a function that selects the chain with the most proof-of-work. There is no change to program logic, no bug fix, and no security-rele…

validation: remove redundant marking in FindMostWorkChain

This commit removes a redundant piece of code in Bitcoin Core's chain-selection logic. Since an earlier change, invalid blocks are already marked as invalid elsewhere, so this inner loop no longer needs to do that marking itself. It is a c…

No security-relevant behavior change: the removed marking is redundant because an earlier invariant guarantees the same state.No new attack surface introduced; no network input, consensus rule, or cryptographic change.Commit message frames the change as code cleanup, not as a vulnerability fix.

test: use static methods and clarify comment in addr_relay

This is a minor cleanup of Bitcoin Core's own functional test code. It changes two helper methods to be static (they don't need access to test class state) and rewrites a comment to be clearer about why the test still sends an initial GETA…
