Recorded in ProtoDatabaseSelector::InitUniqueOrShared when starting, next step is to initialize the unique database.
Recorded in ProtoDatabaseSelector::InitWithDatabase, which is only used by unit tests and perf tests, not a final state.
Recorded in ProtoDatabaseSelector::OnInitUniqueDB when unique database is corrupted, executing callback with kCorrupt.
Recorded in ProtoDatabaseSelector::OnInitUniqueDB when unique DB fails to open and ProtoDatabaseImpl is created without a shared DB provider, should only happen in FakeDB and Perftests. executing callback with kError.
Recorded in ProtoDatabaseSelector::OnGetSharedDBClient when both unique and shared databases fail to open, shared DB can fail to open because SharedProtoDatabase::GetClientAsync returns an error or when SharedProtoDatabaseProvider returns no SharedProtoDatabase instance. callback is executed with kError.
Recorded in ProtoDatabaseSelector::OnGetSharedDBClient when there's no shared DB client and a shared database is requested, callback is executed with kError.
Recorded in ProtoDatabaseSelector::OnGetSharedDBClient when there's no shared DB client because it failed to open and a unique DB was requested, callback is executed with kError because the shared DB could contain unmigrated data.
Recorded in ProtoDatabaseSelector::OnGetSharedDBClient when there’s no unique DB because it failed to open, the callback is executed with kError as the unique DB could contain unmigrated data.
Recorded in ProtoDatabaseSelector::OnInitUniqueDB when unique DB opens successfully but ProtoDatabaseImpl is created without a shared DB provider, should only happen in FakeDB and Perftests. executing callback with kOK.
Recorded in ProtoDatabaseSelector::OnGetSharedDBClient when there‘s no shared DB client because it doesn’t exist in disk and a unique database was requested, callback is executed with kOK and the unique DB is used as this is expected to happen before any migrations.
Recorded in ProtoDatabaseSelector::OnGetSharedDBClient when there‘s no unique DB because it doesn’t exist and the shared DB metadata reports that no migration has been attempted, we set the database as migrated to shared, execute the callback with kOK and use the shared DB.
Recorded in ProtoDatabaseSelector::OnGetSharedDBClient when the unique DB fails to open but the metadata reports that data is now in the shared DB. callback is executed with kOK and the shared DB is used. This is expected to happen after migrating and deleting the unique DB.
Recorded in ProtoDatabaseSelector::MaybeDoMigrationOnDeletingOld when data deletion fails before a migration, we’ll attempt to delete again next time, callback is called with kOK and the old data is used.
Recorded in ProtoDatabaseSelector::OnMigrationTransferComplete when MigrationDelegate::DoMigration returns an error, callback is executed with kOK and the unique DB is used.
Recorded in ProtoDatabaseSelector::OnMigrationTransferComplete when MigrationDelegate::DoMigration returns an error, callback is executed with kOK and the shared DB is used.
Recorded in ProtoDatabaseSelector::OnMigrationCleanupComplete after a successful migration but old data fails to be deleted, callback is executed with kOK and shared DB is used.
Recorded in ProtoDatabaseSelector::OnMigrationCleanupComplete after a successful migration but old data fails to be deleted, callback is executed with kOK and unique DB is used.
Recorded in ProtoDatabaseSelector::OnMigrationCleanupComplete after a successful migration and data deletion, callback is executed with kOK and shared DB is used.
Recorded in ProtoDatabaseSelector::OnMigrationCleanupComplete after a successful migration and data deletion, callback is executed with kOK and unique DB is used.
Recorded in ProtoDatabaseSelector::OnGetSharedDBClient and ProtoDatabaseSelector::MaybeDoMigrationOnDeletingOld, indicates that data will be migrated from unique to shared, not a final state. Next step is calling MigrationDelegate::DoMigration.
Recorded in ProtoDatabaseSelector::OnGetSharedDBClient and ProtoDatabaseSelector::MaybeDoMigrationOnDeletingOld, indicates that data will be migrated from shared to unique, not a final state. Next step is calling MigrationDelegate::DoMigration.
Recorded in SharedProtoDatabase::OnGetClientMetadata when the database for SharedDBMetadataProto fails to load metadata for the specified database, expected for the first time, not a final state.
Recorded in SharedProtoDatabase::OnGetClientMetadata when metadata is retrieved for a client and it has no migration state, we write MIGRATION_NOT_ATTEMPTED back to the database and regardless of the DB’s result we report that no migration has been attempted.
Recorded in SharedProtoDatabase::OnGetClientMetadata when the shared database experienced data corruption in an earlier initialization, shared DB callback is executed with kCorrupt.
Recorded in SharedProtoDatabase::OnGetClientMetadata when the shared database opened successfully without corruption, the shared DB callback is executed with kOK.
Recorded in SharedProtoDatabase::Init and SharedProtoDatabase::CheckCorruptionAndRunInitCallback when the shared proto DB failed to open, the shared DB callback is executed with kError (or any other non kOK result)
Recorded in SharedProtoDatabase::Init when the shared proto DB does not exist, the shared DB callback is executed with kInvalidOperation.
