What

A bare --name or --symbol was parsed as an empty list and fell through to the source scan/database path. Reject an explicitly requested name lookup without names, including abbreviated options, before accessing the database or source tree. The existing empty --nid filter behavior is preserved.

Tested

macOS 27.0.1 arm64, based on main 7dcfff559f68fc4ffb52f836134d3133492a3d00. 31 tests in the affected Python module pass on Python 3.12.14. The new regression also passes on Apple Python 3.9.6.

The new regression fails against the original behavior and passes with this fix. Whitespace and repository conventions checks pass. Full runtime/title execution and Windows/Linux execution were not performed locally.

• No comments in code except technical debt
• Unimplemented paths throw; silent stubs are documented where required
• No notes, investigation .md files or images added to the repository
• New third-party code is a submodule built from source (none added)

For coordination with #6790: the same explicit-empty --name/--symbol inputs currently produce different outcomes. #6790 treats them as an empty selection and avoids database/source scanning; this PR returns a usage error. Could you and that author settle one CLI contract and add a test for the cross-case before either merges? I have not found a reason the empty case must be treated differently from the already-supported explicit-empty --nid case.

Rebase handoff + one test-suite finding — rebased onto current main (authorship unchanged). The conflict in tools/nid_names.py took your rejection path (--name/--symbol requires at least one symbol name).

The finding: your rejection breaks 8 of main's nid_database_cache tests (tools/tests/test_nid_names.py, 35 tests, 8 failures) — they invoke nid_names.py with --name in the empty/no-argument forms and expect success (returncode 0), which your parser.error turns into 2. Those tests were added on main after your branch point, exercising exactly the behaviour your change forbids. So the PR needs either the tests updated to expect the rejection (if the rejection is the intended behaviour — likely, given the PR's title) or the rejection scoped to the forms the tests don't cover. Everything else passes (1337/1339: those 8 plus the known main regression agc_driver_tessellation, #4727) and conventions are green.
