Wcdb Versions Save

Repair Kit

• Fix INTEGER PRIMARY KEY columns not properly recovered.

iOS

• Add WCTColumnCoding support for all WCTValue. Developers can use id<WCTColumnCoding> objects for WINQ and all interfaces.

//WINQ
NSDate *now = [NSDate date];
[database getObjectsOfClass:Message.class fromTable:tableName where:Message.modifedTime==now];

//Interfaces
[database updateAllRowsInTable:tableName 
          onProperty:Message.modifiedTime 
            withValue:[NSDate date]];

• Add monitor for all executed SQL to check WINQ correctness.

//SQL Execution Monitor
[WCTStatistics SetGlobalSQLTrace:^(NSString *sql) {
  NSLog(@"SQL: %@", sql);
}];

• Update WCTTableCoding XCode file template for the best practice of isolating Objective C++ codes. See Wiki page for details.
• Some minor bug fixes.

Android

• Add CursorWindow.windowSize(int) static method to set or get default size for cursor windows.
• SQLiteDatabase.dump() reports IDs for all threads that hold database connections, to aid dead-lock debugging.
• Fix crashing on devices fail to load ICU library.
• Fix SQLiteTrace.onSQLExecuted(...) reports negative execution time.

iOS

• Performance optimization and benchmark. See Wiki page for details.
• Change builtin NSData or NSMutableData column coding to raw data format. To be compatible with earlier versions, call

[WCTCompatible sharedCompatible].builtinNSDataColumnCodingCompatibleEnabled = YES

• Add attach, detach, vacuum, savepoiint, rollback, release, reindex, explain statement and SQLCipher related pragma to WINQ.
• Remove auto increment for insertOrReplace.
• Rename updateTable to updateRowsInTable, and statictics(typo) to statistics.
• Some minor bug fixes.

Android

• Performance optimization and benchmark. See Wiki page for details.
• Expose ProGuard rules to AAR package. Fix crash when minify is enabled in gradle.

iOS

• Add CocoaPods support.
• Add iOS 7 and macOS 10.9 support. Apps using WCDB can target iOS 7 now.
• Fix an issue that [WCTDatabase canOpen] never return YES.
• Fix an issue that the global tracer return some odd values.
• Add @autoreleasepool in runTransaction to avoid OOM.

Android

• Add x86_64 ABI support.
• Publish debug version of AAR and native symbols. To reference debug version of WCDB library, modify your build.gradle

dependencies {
    // Append ":debug@aar" to reference debug library.
    compile 'com.tencent.wcdb:wcdb-android:1.0.1:debug@aar'
}

• Device-locking is available in cipher options. Databases created with device-locking enabled can be only accessed in the same device where the databases are created. Device-locking is currently in alpha stage. You can enable it with the following code:

SQLiteCipherSpec cipher = new SQLiteCipherSpec()
        // add the following line to enable device-locking
        .setCipher(SQLiteCipherSpec.CIPHER_DEVLOCK);
SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(path, key, cipher, ...);

• Various bug fixes.
