WCDB 1.0.4 已发布,WCDB 是腾讯开源的一个高效、完整、易用的移动数据库框架,基于 SQLCipher ,支持 iOS、macOS 和 Android 。

更新内容:

Repair Kit

  • Add sqliterk_cancel function to cancel ongoing output operations.

  • Add corresponding Java interface to cancel operations on Android.

iOS

  • Builtin WCTColumnCoding supports all id<NSCoding> objects now.

  • Compatible with iOS 11.

  • Fullfsync is used by default for data integrity.

  • Add -initWithExistingTag: for WCTDatabase to get existing database without path.

WCTDatabase* database = [WCTDatabase [alloc] initWithPath:path];
database.tag = 123;
WCTDatabase* withoutPath = [[WCTDatabase alloc] initWithExistingTag:123];
  • 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 ANDOR operators in FTS3/4.

  • Use CancellationSignal for canceling BackupKitRecoverKit 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.
