ChangeLog of JS API Changes of the Distributed Data Management Subsystem

Compared with OpenHarmony 3.2 Beta4, OpenHarmony 3.2.10.1(Mr) has the following API changes in the distributed data management subsystem:

cl.distributeddatamgr.1 API Change

APIs in the kv_store component of the distributed data management subsystem are changed:

createKVManager is changed from asynchronous to synchronous, because the execution duration is fixed and short and there is no need to asynchronously wait for the execution result. Therefore, the original APIs function createKVManager(config: KVManagerConfig): Promise<KVManager>; and function createKVManager(config: KVManagerConfig, callback: AsyncCallback): void; are changed to function createKVManager(config: KVManagerConfig): KVManager;.

You need to adapt your applications based on the following information:

Change Impacts

JS APIs in API version 9 are affected. The application needs to adapt these APIs so that it can properly implement functions in the SDK environment of the new version.

Key API/Component Changes

Adaptation Guide

The following illustrates how to call createKVManager to create a KVManager object.

Stage model:

import AbilityStage from '@ohos.application.Ability'
let kvManager;
export default class MyAbilityStage extends AbilityStage {
    onCreate() {
        console.log("MyAbilityStage onCreate")
        let context = this.context
        const kvManagerConfig = {
            context: context,
            bundleName: 'com.example.datamanagertest',
        }
        try {
            kvManager = distributedKVStore.createKVManager(kvManagerConfig);          
        } catch (e) {
            console.error(`Failed to create KVManager.code is ${e.code},message is ${e.message}`);
        }
    }
}

FA model:

import featureAbility from '@ohos.ability.featureAbility'
let kvManager;
let context = featureAbility.getContext()
const kvManagerConfig = {
    context: context,
    bundleName: 'com.example.datamanagertest',
}
try {
    kvManager = distributedKVStore.createKVManager(kvManagerConfig);
} catch (e) {
    console.error(`Failed to create KVManager.code is ${e.code},message is ${e.message}`);
}

cl.distributeddatamgr.2 Migration of function getRdbStoreV9 from @ohos.data.rdb.d.ts to @ohos.data.relationalStore.d.ts.

Change Impacts

function getRdbStore(context: Context, config: StoreConfig, callback: AsyncCallback<RdbStore>): void;
function getRdbStore(context: Context, config: StoreConfig): Promise<RdbStore>;

Adaptation Guide

• import rdb from "@ohos.data.rdb" is changed to import rdb from "@ohos.data.relationalStore".
• The names of relevant methods should be changed according to the preceding changes.

function deleteRdbStoreV9(context: Context, name: string, callback: AsyncCallback<void>): void;
function deleteRdbStoreV9(context: Context, name: string): Promise<void>;

The APIs are migrated from @ohos.data.rdb.d.ts to @ohos.data.relationalStore.d.ts.

function deleteRdbStoreV9(context: Context, name: string, callback: AsyncCallback<void>): void;
function deleteRdbStoreV9(context: Context, name: string): Promise<void>;

Adaptation Guide * import rdb from "@ohos.data.rdb" is changed to import rdb from "@ohos.data.relationalStore". * The names of relevant methods should be changed according to the preceding changes.

Adaptation Guide * import rdb from "@ohos.data.rdb" is changed to import rdb from "@ohos.data.relationalStore". * The names of relevant APIs should be changed according to the preceding changes.

cl.distributeddatamgr.5 Migration of enum SecurityLevel from @ohos.data.rdb.d.ts to @ohos.data.relationalStore.d.ts

Change Impacts

The application needs to adapt these APIs so that it can be properly compiled in the SDK environment of the new version.

Key API/Component Changes

enum SecurityLevel is migrated from ohos.data.rdb.d.ts to @ohos.data.relationalStore.d.ts.

Adaptation Guide * import rdb from "@ohos.data.rdb" is changed to import rdb from "@ohos.data.relationalStore". * The names of relevant APIs should be changed according to the preceding changes.

cl.distributeddatamgr.6 Migration of interface RdbStoreV9 from @ohos.data.rdb.d.ts to @ohos.data.relationalStore.d.ts

Change Impacts
