A parity guard already existed for DriverTypeNames <-> the /raw driver picker,
but not for the two dispatch maps downstream, so a driver could be registered,
offered in the picker, and then have no config form. That is exactly what
happened to Calculation (G-1) and to Sql/MTConnect/Calculation on the device
modal (G-2) — both survived review because nothing could see them.
The maps had to become data first. A Razor @switch compiles into
BuildRenderTree's IL, so no test can enumerate its cases; the picker guard
works only because RawDriverTypeDialog keeps its data in a field the markup
enumerates. Both modals now render from DriverConfigFormMap / DeviceFormMap
through <DynamicComponent>, and being public those maps need none of the
picker test's BindingFlags.NonPublic fragility.
- G-1 CalculationDriverForm.razor — RunTimeout was unauthorable via the UI.
- G-2 Sql/MTConnect/Calculation declared single-connection rather than given
hollow device forms; each holds one connection at the driver level.
- G-3 DriverConfigModal's hardcoded "Galaxy or Mqtt" -> IsSingleConnection, so
Sql/MTConnect authors are no longer sent to a device form with no endpoint.
- G-4 DriverFormMapParityTests (5, both directions) + DriverDispatchMapParityTests.
- G-5 CsvColumnMap entries for Sql, Mqtt, MTConnect.
- G-6 RawBrowseCommitMapper Sql branch — and the browser end, which the audit
missed: SqlBrowseSession emitted NO AddressFields, so a browsed leaf carried
only a column name, and a column alone cannot address a Sql tag. It now
travels schema/table/column and the mapper builds a WideRow config from them.
A branch alone would have produced a half-built blob.
Two findings while writing the guards. The G-6 test showed Modbus and
Calculation also hit the generic address fallback — correctly, as neither is
browsable — so it asserts the fall-through set EQUALS a documented
non-browsable list in both directions; a one-way check would let a newly
browsable driver be quietly added to the exclusion list. And
TagConfigDriverTypeNameGuardTests was hollow: it enumerated a hand-written
TheoryData that had already drifted (omitting Galaxy, Sql and Mqtt), guarding
renames but not gaps. Now enumerated from the map with a coverage test facing
the other way.
Live-verified on docker-dev, since this repo has no bUnit and no unit test
reaches Blazor parameter binding: opened Calculation's config (previously "No
typed config form"), typed 3500, saved, reopened — the value persisted, so the
DynamicComponent two-way binding round-trips. Sql's form renders fully and now
reads "This driver holds a single connection, authored above".
AdminUI.Tests 930 passed.
Walks schemas -> tables/views -> columns via ISqlDialect's catalog SQL, with
@schema/@table bound as parameters at every level. Column leaves carry the
dialect-mapped DriverDataType in the attribute side-panel (ViewOnly, read-only
v1).
The NodeId encoding deliberately departs from the design sketch's literal
`schema.table|column`: SQL Server permits `.` and `|` inside a quoted
identifier, so that form mis-parses (main.a.b|c reads equally as schema
`main`+table `a.b` and schema `main.a`+table `b`) and silently binds an
operator's tag to the wrong column. SqlBrowseNodeId encodes
`<kind>:<part>[|<part>...]` with `\`/`|` escaped and the kind prefix carrying
the arity; it is public because the picker body decodes it back.
The session owns the connection it is handed and closes it on dispose -- the
registry-held session is the only lifetime hook, so a non-owning session would
leak one pooled connection per reaped picker. Per-call work stays bounded by
the AdminUI's existing 20s linked CTS (BrowserSessionService.PerCallTimeout);
no second deadline is invented here.
