# TestSetups Module Documentation

## 1. Purpose

This module provides the database access layer for test setup configuration data within the DataPRO system. It defines and implements CRUD operations for four primary entities: graphs (`IGraphs`/`Graphs`), calculated channels (`ICalculatedChannels`/`CalculatedChannels`), regions of interest (`IRegionsOfInterest`), and test setup metadata (`ITestSetups`). The module abstracts SQL Server stored procedure calls behind strongly-typed interfaces, handling user authentication, parameter marshalling, and error propagation. It serves as the persistence boundary between the application's domain model and the relational database.

## 2. Public Interface

### IGraphs Interface

| Method | Signature |
|--------|-----------|
| `GraphsGet` | `ulong GraphsGet(IUserDbRecord user, IConnectionDetails connection, int? graphId, int? testSetupId, out IGraphRecord[] records)` |
| `GraphsUpdate` | `ulong GraphsUpdate(IUserDbRecord user, IConnectionDetails connection, IGraphRecord record)` |
| `GraphsInsert` | `ulong GraphsInsert(IUserDbRecord user, IConnectionDetails connection, ref IGraphRecord record)` |
| `GraphsDelete` | `ulong GraphsDelete(IUserDbRecord user, IConnectionDetails connection, int graphId)` |

**Behaviors:**
- `GraphsGet`: Retrieves graph records filtered by optional `graphId` and/or `testSetupId`. Returns empty array if no matches.
- `GraphsUpdate`: Updates an existing graph record identified by `record.GraphId`.
- `GraphsInsert`: Inserts a new graph record. The `ref` parameter is mutated with the new `GraphId` from the database.
- `GraphsDelete`: Removes a graph record by its database ID.

### ICalculatedChannels Interface

| Method | Signature |
|--------|-----------|
| `CalculatedChannelsDelete` | `ulong CalculatedChannelsDelete(IUserDbRecord user, IConnectionDetails connection, int calculatedChannelId)` |
| `CalculatedChannelsGet` | `ulong CalculatedChannelsGet(IUserDbRecord user, IConnectionDetails connection, int? calculatedChannelId, string testSetupName, out ICalculatedChannelRecord[] records)` |
| `CalculatedChannelsInsert` | `ulong CalculatedChannelsInsert(IUserDbRecord user, IConnectionDetails connection, ref ICalculatedChannelRecord record)` |
| `CalculatedChannelsUpdate` | `ulong CalculatedChannelsUpdate(IUserDbRecord user, IConnectionDetails connection, ICalculatedChannelRecord record)` |

**Behaviors:**
- `CalculatedChannelsGet`: Retrieves calculated channel records filtered by optional `calculatedChannelId` and/or `testSetupName`.
- `CalculatedChannelsInsert`: Inserts a new calculated channel. The `ref` parameter is mutated with the new `Id` from the database.
- `CalculatedChannelsUpdate`: Updates an existing calculated channel identified by `record.Id`.
- `CalculatedChannelsDelete`: Removes a calculated channel by its database ID.

### IRegionsOfInterest Interface

| Method | Signature |
|--------|-----------|

## 3. Invariants

1. **Return Value Convention**: All methods return `ulong` where `0` equals `ERROR_SUCCESS`. Any non-zero value indicates an error.

2. **Authentication Requirement**: All public methods in `Graphs` and `CalculatedChannels` implementations call `DbAPI.Connections.IsUserLoggedIn(user, connection)` before executing database operations. Failure returns `ErrorCodes.ERROR_ACCESS_DENIED`.

3. **Null Record Handling**: Insert and Update methods in `CalculatedChannels` check for null `record` parameter and return `ErrorCodes.ERROR_MISSING_PARAMETER` if null.

4. **Resource Cleanup**: All implementations use `try/finally` blocks to dispose of `SqlCommand` and its `Connection`. The `SqlConnection` is disposed via `cmd.Connection.Dispose()`.

5. **Stored Procedure Usage**: All database operations use stored procedures (e.g., `sp_CalculatedChannelsInsert`, `sp_TestGraphsGet`). No inline SQL is used.

6. **Output Parameter Mutation**: Insert methods (`GraphsInsert`, `CalculatedChannelsInsert`) use `ref` parameters to return the newly assigned database ID to the caller.

7. **Error Propagation**: Stored procedures return errors via `@errorNumber` and `@errorMessage` output parameters. Non-zero error numbers are logged via `LogManager.Log` and result in `ErrorCodes.ERROR_UNKNOWN` being returned.

## 5. Gotchas

1. **Incorrect Log Event in `CalculatedChannelsGet`**: The implementation logs errors using `LogEvents.Graphs` instead of `LogEvents.CalculatedChannels`:
   ```csharp
   LogManager.Log(TraceEventType.Error, LogManager.LogEvents.Graphs, $"sp_CalculatedChannelsGet failed: {ex.Message}");
   ```
   This appears to be a copy-paste error.

2. **Incorrect Log Message in `GraphsDelete`**: The exception log message incorrectly references "GraphsInsert":
   ```csharp
   LogManager.Log(TraceEventType.Error, LogManager.LogEvents.Graphs, $"GraphsInsert exception {ex.Message}");
   ```

3. **Inconsistent Command Disposal**: The `Graphs` class only disposes `cmd.Connection` in its `finally` block, while `CalculatedChannels` disposes both `cmd.Connection` and `cmd`. This may indicate inconsistent cleanup patterns.

4. **Missing XML Documentation**: The `IRegionsOfInterest` interface lacks XML documentation for `TestSetupROIsDelete`, `TestSetupROIsInsert`, `TestSetupROIsGet`, `ROIPeriodChannelsInsert`, and `ROIPeriodChannelsGet` methods.

5. **Undocumented `clientDbVersion` Parameter**: The purpose and valid values of the `clientDbVersion` parameter (present in `IRegionsOfInterest` and `ITestSetups` methods) is not documented in the interface. Comments in `TestSetupsGet` hint at Version 91 database compatibility concerns, but specifics are unclear from source alone.

6. **InputChannelIds Serialization**: `CalculatedChannelsInsert` and `CalculatedChannelsUpdate` serialize `InputChannelIds` using `Utility.GetBytesFromStringArray()` with `CultureInfo.InvariantCulture.TextInfo.ListSeparator`. The deserialization logic is not present in these files.
