[auth] [linux] ente data in user home - infinite loading if ~/ente file exists

[nktnet1]

Description

When using ente, a directory and sqlite3 database is created in the user's home folder:

$ file ~/ente/.ente.authenticator.db
/home/nktnet/ente/.ente.authenticator.db: SQLite 3.x database, user version 1, last written using SQLite version 3046000, file counter 2, database pages 4, cookie 0x1, schema 4, UTF-8, version-valid-for 2

Deleting/renaming the directory means that user details are lost.

Worse, having a file with path ~/ente instead of a directory means that ente-auth will load infinitely (as it cannot read from the sqlite database).

A better way to store user configurations would be to follow the standards set by XDG Base Directory, whereby this sqlite database file is stored in $XDG_DATA_HOME, e.g.

${XDG_DATA_HOME}/ente/.ente.authenticator.db         # which defaults to:
${HOME}/.local/share/.ente/.ente.authenticator.db

This is similar to #2563, where ente is using ~/temp instead of ${XDG_CACHE_HOME}/ente, leading to user files being unintentionally deleted.

The code in question is below:

ente/auth/lib/store/authenticator_db.dart

Lines 13 to 39 in 8d91b85

	class AuthenticatorDB {
	static const _databaseName = "ente.authenticator.db";
	static const _databaseVersion = 1;
	static const entityTable = 'entities';
	AuthenticatorDB._privateConstructor();
	static final AuthenticatorDB instance = AuthenticatorDB._privateConstructor();
	static Future<Database>? _dbFuture;
	Future<Database> get database async {
	_dbFuture ??= _initDatabase();
	return _dbFuture!;
	}
	Future<Database> _initDatabase() async {
	if (Platform.isWindows || Platform.isLinux) {
	var databaseFactory = databaseFactoryFfi;
	return await databaseFactory.openDatabase(
	await DirectoryUtils.getDatabasePath(_databaseName),
	options: OpenDatabaseOptions(
	version: _databaseVersion,
	onCreate: _onCreate,
	),
	);
	}
