Walkthrough

The changes update the help text for several wallet-related RPC commands. In src/wallet/rpc/addresses.cpp, the help output for the newkeypool command is modified to add a newline and a note indicating that it is only compatible with legacy wallets. In src/wallet/rpc/backup.cpp, similar notes are appended to the help messages for the importelectrumwallet and dumphdinfo commands. No changes are made to the logic, parameters, or control flow of these commands; only the descriptive help strings are updated.

Learning: Pull request #6543 is focused on move-only changes and refactoring, specifically backporting from Bitcoin. Behavior changes should be proposed in separate PRs.

Timestamp: 2025-06-09T16:43:20.996Z
Learning: In the test framework consolidation PR (#6718), user kwvg prefers to limit functional changes to those directly related to MasternodeInfo, avoiding scope creep even for minor improvements like error handling consistency.

Learning: The `GetWallet()` function calls in `src/wallet/rpcwallet.cpp` are properly validated with null checks that throw appropriate RPC errors, making additional validation unnecessary.

🔇 Additional comments (3)

src/wallet/rpc/addresses.cpp (1)

317-318: Help-string update is correct and consistent

The extra newline plus the explicit legacy-wallet note mirror wording used elsewhere (e.g. importprivkey). No functional impact; good to merge.

src/wallet/rpc/backup.cpp (2)

647-649: Clarifies legacy-only status – looks good

Matches the convention adopted for other RPCs; text/formatting are fine.

873-874: Consistent legacy-wallet disclaimer added

Addition aligns dumphdinfo with the rest of the RPC help. No further action required.
