validation: In AcceptBlock, ignore flush result

This change fixes a subtle bug in how Bitcoin Core reports disk flush errors during block acceptance. Previously, if writing block data to disk failed (for example, because the disk was full during pruning), the error could be misreported …

test: Add test for BuildSkip() and skip heights

This commit only adds a new automated test for an existing Bitcoin Core data structure. It does not change any production code, network behavior, or wallet logic. There is no security issue here.

rpc: Fix for duplicate external signers case

This commit fixes a bug in how Bitcoin Core lists external hardware wallets (signers). Previously, if the list contained duplicate signers, the code would stop processing entirely after the first duplicate, potentially hiding valid non-dup…

Change CChain::FindFork() to take ref

This is a small internal code cleanup in Bitcoin Core. It changes one function, CChain::FindFork(), so that callers must pass a valid block object directly rather than a pointer that might be null. The function previously handled null poin…

Change pindexMostWork parameter of ActivateBestChainStep() to reference

This is a small internal code cleanup in Bitcoin Core. It changes one function parameter from a pointer (which could theoretically be null) to a reference (which cannot be null), because the caller always passes a valid object anyway. Ther…

Change CChain::Next() to take reference

This commit tightens up a low-level helper function in Bitcoin Core that finds the next block in the chain. It changes the function so callers must pass a real block object rather than a potentially-null pointer, and it adds a safety check…

API hardening: pointer parameter replaced with reference to enforce non-null inputNull-check added: NextSyncBlock() asserts FindFork() result before useDefensive refactor across consensus-adjacent code paths (net processing, validation, REST, indexes)

test: Add CChain::FindFork() tests

This commit only adds new unit tests for an existing function called CChain::FindFork(). It does not change any production code, so it cannot directly introduce a security vulnerability or fix one. It is a routine test-only change.

This commit only adds new automated unit tests for the CChain class in Bitcoin Core. It does not change any production code, fix bugs, or introduce security-relevant behavior. The tests verify basic chain operations like height, tip, index…

Change CChain::Contains() to take reference

This commit hardens a core Bitcoin method called CChain::Contains() so it can no longer be accidentally called with a null (missing) block pointer, which would crash the node. The change turns the method's input from a pointer into a refer…

test: Add clean shutdown to Socks5Server

This is a test-only change to the SOCKS5 server helper used in Bitcoin Core's functional tests. It makes the test server shut down its background connection-handler threads cleanly instead of leaving them running. It does not affect the Bi…

This is a small internal code cleanup in Bitcoin Core. It changes one function so it accepts a direct reference to a block index object instead of a pointer. The behavior of the program is unchanged; the only difference is that callers now…
