From 3c390cbd97ce0d1f31732d2ba090ba49ca7ce305 Mon Sep 17 00:00:00 2001 From: Yuki Yamazaki Date: Sat, 27 Sep 2025 20:16:33 +0000 Subject: [PATCH 1/9] feat: implement SQLDelight database migration system MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add DatabaseMigrationManager for automatic schema migrations - Add ApplicationVersion for version and schema tracking - Update all SqlDelightDatabaseProviders to use migration system - Add thread-safe migration with proper transaction handling - Fail fast when database version is newer than application - Add migration placeholder files for future schema changes - Add comprehensive migration guide documentation - Add tests for migration manager and version tracking This enables automatic database schema updates when the application version changes, eliminating manual migration steps for users. 🤖 Generated with Claude Code Co-Authored-By: Claude --- .../sqldelight/SqlDelightDatabaseProvider.kt | 25 +- .../src/main/sqldelight/migrations/1.sqm | 23 ++ .../sqldelight/SqlDelightDatabaseProvider.kt | 25 +- .../src/main/sqldelight/migrations/1.sqm | 16 + .../sqldelight/SqlDelightDatabaseProvider.kt | 41 ++- .../src/main/sqldelight/migrations/1.sqm | 25 ++ .../development/database-migration-guide.md | 274 ++++++++++++++++++ .../database/DatabaseMigrationManager.kt | 188 ++++++++++++ .../version/ApplicationVersion.kt | 123 ++++++++ .../database/DatabaseMigrationManagerTest.kt | 199 +++++++++++++ .../version/ApplicationVersionTest.kt | 91 ++++++ 11 files changed, 1018 insertions(+), 12 deletions(-) create mode 100644 contexts/device-synchronization/infrastructure/src/main/sqldelight/migrations/1.sqm create mode 100644 contexts/event-store/infrastructure/src/main/sqldelight/migrations/1.sqm create mode 100644 contexts/scope-management/infrastructure/src/main/sqldelight/migrations/1.sqm create mode 100644 docs/guides/development/database-migration-guide.md create mode 100644 platform/infrastructure/src/main/kotlin/io/github/kamiazya/scopes/platform/infrastructure/database/DatabaseMigrationManager.kt create mode 100644 platform/infrastructure/src/main/kotlin/io/github/kamiazya/scopes/platform/infrastructure/version/ApplicationVersion.kt create mode 100644 platform/infrastructure/src/test/kotlin/io/github/kamiazya/scopes/platform/infrastructure/database/DatabaseMigrationManagerTest.kt create mode 100644 platform/infrastructure/src/test/kotlin/io/github/kamiazya/scopes/platform/infrastructure/version/ApplicationVersionTest.kt diff --git a/contexts/device-synchronization/infrastructure/src/main/kotlin/io/github/kamiazya/scopes/devicesync/infrastructure/sqldelight/SqlDelightDatabaseProvider.kt b/contexts/device-synchronization/infrastructure/src/main/kotlin/io/github/kamiazya/scopes/devicesync/infrastructure/sqldelight/SqlDelightDatabaseProvider.kt index 1d36c9623..d732af1b4 100644 --- a/contexts/device-synchronization/infrastructure/src/main/kotlin/io/github/kamiazya/scopes/devicesync/infrastructure/sqldelight/SqlDelightDatabaseProvider.kt +++ b/contexts/device-synchronization/infrastructure/src/main/kotlin/io/github/kamiazya/scopes/devicesync/infrastructure/sqldelight/SqlDelightDatabaseProvider.kt @@ -3,20 +3,30 @@ package io.github.kamiazya.scopes.devicesync.infrastructure.sqldelight import app.cash.sqldelight.db.SqlDriver import app.cash.sqldelight.driver.jdbc.sqlite.JdbcSqliteDriver import io.github.kamiazya.scopes.devicesync.db.DeviceSyncDatabase +import io.github.kamiazya.scopes.platform.infrastructure.database.DatabaseMigrationManager +import io.github.kamiazya.scopes.platform.infrastructure.version.ApplicationVersion /** * Provides SQLDelight database instances for Device Synchronization. + * + * This provider creates databases with migration support. */ object SqlDelightDatabaseProvider { /** * Creates a new DeviceSyncDatabase instance. + * Automatically handles schema creation and migration based on version differences. */ fun createDatabase(databasePath: String): DeviceSyncDatabase { val driver: SqlDriver = JdbcSqliteDriver("jdbc:sqlite:$databasePath") -
