SQLite's WAL mode requires shared-memory (mmap) coordination and fcntl byte-range locks that don't reliably work on network filesystems. Upstream documents this explicitly: https://www.sqlite.org/wal.html#sometimes_queries_return_sqlite_busy_in_wal_mode On NFS / SMB / some FUSE mounts / WSL1, 'PRAGMA journal_mode=WAL' raises 'sqlite3.OperationalError: locking protocol' (SQLITE_PROTOCOL). Before this change, every feature backed by state.db or kanban.db broke silently: - /resume, /title, /history, /branch returned 'Session database not available.' with no cause - gateway logged the init failure at DEBUG (invisible in errors.log) - kanban dispatcher crashed every 60s, driving the known migration race (duplicate column name: consecutive_failures, #21708 / #21374) Changes: - hermes_state.apply_wal_with_fallback(): shared helper that tries WAL and falls back to DELETE on SQLITE_PROTOCOL-style errors with one WARNING explaining why - hermes_state.get_last_init_error() + format_session_db_unavailable(): capture the init failure cause and surface it in user-facing strings (with an NFS/SMB pointer for 'locking protocol') - hermes_cli/kanban_db.connect(): use the shared helper - gateway/run.py: bump SessionDB init failure log DEBUG -> WARNING (matches cli.py's existing correct behavior) - cli.py (4 sites) + gateway/run.py (5 sites): replace bare 'Session database not available.' with format_session_db_unavailable() Tests: 12 new tests in tests/test_hermes_state_wal_fallback.py + 1 new test in tests/hermes_cli/test_kanban_db.py. Existing suites (state, kanban, gateway, cli) remain green for all tests unrelated to pre-existing failures on main. Evidence: real-world user on NFSv3 mount (172.26.224.200:d2dfac12/home, local_lock=none) reporting 'Session database not available.' on /resume; 'locking protocol' appears in 4 distinct log entries across backup, kanban, TUI, and CLI paths in the same session. closes #22032 |
