    • 🐎 Some minor bug fixes, performance improvement and code refactor.

    Android

    • ➕ Add asynchronous checkpointing support and custom checkpointing callback. This can improve performance in WAL mode.
    SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabaseInWalMode(...);

// Use asynchronous checkpointing.
db.setAsyncCheckpointEnabled(true);

// OR use custom checkpointer.
SQLiteCheckpointListener callback = new SQLiteCheckpointListener() {
    //...
};
db.setCheckpointCallback(callback);
    • ➕ Add SQLiteTrace.onConnectionObtained(...) interface to trace concurrency performance.
    • ➕ Add cancelable version of SQLiteDatabase.execSQL(). See CancellationSignal for details.
    CancellationSignal signal = new CancellationSignal();
db.execSQL(longRunningSQL, args, signal);

// on another thread
signal.cancel();
    • Enable SQLITE_ENABLE_FTS3_PARENTHESIS compilation option on SQLCipher, which enables AND, OR operators in FTS3/4.
    • 🚦 Use CancellationSignal for canceling BackupKit, RecoverKit and RepairKit operations. See repair sample for details.
    • ➕ Add callback interface for RepairKit to show progress to the users. See RepairKit.Callback and RepairKit.setCallback().
    • Do not load libwcdb.so if it's already loaded on the first use. This makes WCDB compatible to Tinker framework.
    • 🛠 Various bug fixes.
