Summary of ChangesHello @kamiazya, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces a foundational automatic database migration system for SQLDelight databases. The primary goal is to simplify schema evolution by automating updates when the application version changes, thereby reducing manual intervention and potential errors. The system is designed with safety in mind, incorporating version checks to prevent running older application versions on newer databases, and includes a clear guide for developers to easily manage future schema changes.

Code Review
This pull request introduces a robust and well-designed database migration system using SQLDelight. The implementation is clean, follows good architectural principles, and includes comprehensive documentation and testing. The core DatabaseMigrationManager is thread-safe and handles various migration scenarios gracefully, including new databases, existing unversioned databases, and preventing downgrades. The addition of version tracking in ApplicationVersion is also a great feature for maintainability. My review includes a few suggestions to improve efficiency in the database providers and to correct some examples in the new migration guide.
| // Create the database schema | ||
| DeviceSyncDatabase.Schema.create(driver) | ||
| // Perform migration if needed | ||
| val migrationManager = DatabaseMigrationManager.createDefault() |
There was a problem hiding this comment.
A new instance of DatabaseMigrationManager is created on every call to createDatabase. Since SqlDelightDatabaseProvider is a singleton (object), it's more efficient to create a single, reusable instance of the manager as a private property of the object.
This avoids unnecessary object creation and improves performance slightly. You can apply this pattern to all SqlDelightDatabaseProvider files.
Example of the recommended structure:
object SqlDelightDatabaseProvider {
private val migrationManager = DatabaseMigrationManager.createDefault()
fun createDatabase(databasePath: String): DeviceSyncDatabase {
val driver: SqlDriver = JdbcSqliteDriver("jdbc:sqlite:$databasePath")
// Perform migration if needed
migrationManager.migrate(
driver = driver,
schema = DeviceSyncDatabase.Schema,
targetVersion = ApplicationVersion.SchemaVersions.DEVICE_SYNCHRONIZATION
)
// ...
}
// ...

The code example for using a MigrationCallback with driver.execute appears to have an incorrect signature. The binder argument should be passed as a trailing lambda, not as a direct function call in the argument list. This will be confusing for developers and lead to code that doesn't compile.

| null, | |
| "UPDATE scopes SET status = 'archived' WHERE updated_at < ?", | |
| 1, | |
| bindLong(0, thirtyDaysAgo) | |

The unit test example refers to TestSchema, which is not defined in the guide. This will likely confuse developers trying to implement a similar test. It should probably be schema to match the variable that would typically be defined in a test setup.

The else branch in the mapper lambda is unreachable because a COUNT(*) query in SQL always returns exactly one row. While this doesn't cause a bug, it can be simplified to make the code cleaner and show a clearer understanding of the SQL behavior.
mapper = { cursor ->
cursor.next()
cursor.getLong(0) == 0L
},- Fixed import paths for Logger and ConsoleLogger (use logging package) - Replaced SqlDriver.newTransaction() with raw SQL transactions (BEGIN/COMMIT/ROLLBACK) - Fixed executeQuery return type handling (.value accessor) - Updated error logging to use correct Logger API signature - Removed incorrect afterVersion lambda from schema.migrate call The compilation errors were caused by: 1. Wrong package imports for observability classes 2. SqlDriver doesn't have newTransaction() method - using raw SQL instead 3. executeQuery returns QueryResult which needs .value accessor 4. Logger.error() requires throwable parameter, not just message

platform/infrastructure/src/test/kotlin/io/github/kamiazya/scopes/platform/infrastructure/database/DatabaseMigrationManagerTest.kt (1)
128-160: Add a test: database version newer than app should fail fast.Cover the branch where currentVersion > targetVersion to lock the expected exception and message.
contexts/scope-management/infrastructure/src/main/kotlin/io/github/kamiazya/scopes/scopemanagement/infrastructure/sqldelight/SqlDelightDatabaseProvider.kt (2)
36-49: Verify and mitigate breaking change in return type (ScopeManagementDatabase → ManagedDatabase).This is a public API change; downstream callers expecting ScopeManagementDatabase will break. Consider one of:
- Keep the function signature returning ScopeManagementDatabase and still return ManagedDatabase (it implements ScopeManagementDatabase) to preserve source/binary compatibility, and add a new createManagedDatabase() for explicit resource ownership; or
- Keep the new return type but add a deprecation period with alternative factory helpers at call sites.
61-71: Enable foreign key enforcement for safety.Set PRAGMA foreign_keys = ON after opening the driver (both on-disk and in-memory) to ensure referential integrity.
Apply:
ScopeManagementDatabase.Schema.create(driver) // Set the version for consistency driver.execute( identifier = null, sql = "PRAGMA user_version = ${ApplicationVersion.SchemaVersions.SCOPE_MANAGEMENT}", parameters = 0 ) + // Enforce FK constraints + driver.execute( + identifier = null, + sql = "PRAGMA foreign_keys = ON", + parameters = 0 + )platform/infrastructure/src/main/kotlin/io/github/kamiazya/scopes/platform/infrastructure/database/DatabaseMigrationManager.kt (1)
41-48: Pre-migration “no version but not empty” path risks masking unknown state. Require an explicit bootstrap version or callback.Blindly forcing version=1 may be wrong if the DB came from a newer build. Consider taking a required parameter (e.g., bootstrapVersionProvider) or fail fast unless the caller opts in.

Enable foreign keys in in-memory database provider.
Line 31 enables foreign keys for on-disk databases, but the in-memory path skips it. That leaves test setups without FK enforcement, letting violations slip through locally while production fails. Please mirror the production behaviour.

Enable foreign keys for the in-memory event-store database too.
Like the device-sync provider, tests using this in-memory DB won't enforce FK constraints, diverging from production. Enable them to keep parity.

Fail fast on malformed semantic version segments
parseVersion currently coerces any non-numeric segment to 0, so a typo like "1.0.O" is silently treated as "1.0.0". That masks configuration/version corruption and lets migrations proceed under a wrong assumption, which clashes with our requirement to fail fast on invalid configuration. Please reject malformed segments instead of defaulting to zero. As per coding guidelines.
fun parseVersion(version: String): Triple<Int, Int, Int> {
- val parts = version.split(".")
- return Triple(
- parts.getOrNull(0)?.toIntOrNull() ?: 0,
- parts.getOrNull(1)?.toIntOrNull() ?: 0,
- parts.getOrNull(2)?.toIntOrNull() ?: 0
- )
+ val parts = version.split(".")
+
+ fun parsePart(index: Int): Int {
+ val value = parts.getOrNull(index) ?: return 0
+ require(value.toIntOrNull() != null) {
+ "Invalid semantic version segment '$value' in '$version'"
+ }
+ return value.toInt()
+ }
+
+ return Triple(
+ parsePart(0),

Preserve the original migration failure cause
The error("Migration failed: …") path throws a brand-new IllegalStateException, so every upstream caller loses the real stack trace and exception type from the driver/schema. That makes postmortems almost impossible. We already expose DatabaseMigrationException; please wrap the original throwable (or rethrow it if it’s already that type) and keep the cause attached when logging.
} catch (e: Exception) {
if (transactionActive) {
try {
driver.execute(null, "ROLLBACK", 0)
} catch (rollbackException: Exception) {
// Log rollback failure but preserve original exception
logger.error("Failed to rollback migration transaction", throwable = rollbackException)
}
}
- error("Migration failed: ${e.message}")
+ val wrapped = if (e is DatabaseMigrationException) e else DatabaseMigrationException("Migration failed", e)
+ logger.error(wrapped.message ?: "Migration failed", throwable = wrapped)
+ throw wrapped
}Apply the same preservation logic to the other catch blocks so every migration failure surfaces with its original cause.
