rpc: reject empty node argument in addnode

This change fixes a minor bug in Bitcoin Core's RPC command `addnode`. Previously, if a user passed an empty or whitespace-only address, Bitcoin Core would add it to its persistent 'try to connect' list and keep retrying forever, even thou…

init: ignore empty addnode values

This change fixes a minor startup bug in Bitcoin Core where an empty -addnode setting (for manually adding network peers) would create a useless peer record that the software tried to connect to over and over. Now empty or whitespace-only …

test: cover unused mempool space in coins cache

This is a routine test-only change. It adjusts an existing unit test to better exercise how Bitcoin Core's coin cache behaves when memory reserved for the mempool is not actually being used by the mempool. No production code was changed, s…

mining: add reason and debug output to submitSolution

This commit changes the internal mining interface so that when a miner submits a solved block through the IPC interface, the caller now receives a specific rejection reason (like 'bad-version', 'duplicate', or 'inconclusive') instead of ju…

Interface versioning change to prevent old IPC clients from decoding corrupt result fieldsDeprecated stub throws explicit runtime error instead of silently returning incompatible dataReturn value semantics changed: submitSolution now returns true only for accepted new blocks, not duplicates

refactor: centralize SubmitBlock result handling

This is a small internal cleanup in Bitcoin Core's block submission code. It moves a duplicate-check and success-calculation that existed in two places into a single shared helper function. The visible behavior for the mining RPCs is inten…

mining: clarify SubmitBlock result handling

This Bitcoin Core commit tightens how the mining interface reports whether a submitted block succeeded or failed. Previously, a block could be accepted but not connected to the chain (for example, a valid but lower-work 'stale' block), and…
