 ## IDL Overview
 To ensure successful communications between the client and server, interfaces recognized by both parties must be defined. The OpenHarmony Interface Definition Language (IDL) is a tool for defining such interfaces. OpenHarmony IDL decomposes objects to be transferred into primitives that can be understood by the operating system and encapsulates cross-boundary objects based on developers' requirements.

 ### Specifications for Compiling IDL Files
 Only one interface type can be defined in an IDL file, and the interface name must be the same as the file name. The interface definition of the IDL file is described in Backus-Naur form (BNF). The basic definition format is as follows:
+
 ```
 [<*interface_attr_declaration*>]interface<*interface_name_with_namespace*>{<*method_declaration*>}
 ```
+
 In the preceding information, <*interface_attr_declaration*> declares interface attributes. Currently, only the **oneway** attribute is supported, indicating that all methods in the interface are unidirectional. Such a method returns value without waiting for the execution to complete. This attribute is optional. If this attribute is not set, synchronous call is used. The interface name must contain the complete interface header file directory, namespace, and method declaration. Empty interfaces are not allowed.
 The method declaration format in the interface is as follows:
+
 ```
 [<*method_attr_declaration*>]<*result_type*><*method_declaration*>
 ```
+
 In the preceding information, <*method_attr_declaration*> describes the interface attributes. Currently, only the **oneway** attribute is supported, indicating that the method is unidirectional. Such a method returns value without waiting for the execution to complete. This attribute is optional. If this attribute is not set, synchronous call is used. <*result_type*> indicates the type of the return value, and <*method_declaration*> indicates the method name and parameter declaration.
 The parameter declaration format is as follows:
+
 ```
 [<*formal_param_attr*>]<*type*><*identifier*>
 ```
+
 The value of <*formal_param_attr*> can be **in**, **out**, or **inout**, indicating that the parameter is an input parameter, an output parameter, or both an input and an output parameter, respectively. A **oneway** method does not allow **output** or **inout** parameters or return values.

 Data of a temporary widget is not persistently stored. If the widget framework is killed and restarted, data of a temporary widget will be deleted. However, the widget provider is not notified of which widget is deleted, and still keeps the data. Therefore, the widget provider should implement data clearing. In addition, the widget host may convert a temporary widget into a normal one. If the conversion is successful, the widget provider should process the widget ID and store the data persistently. This prevents the widget provider from deleting persistent data when clearing temporary widgets.

+OpenHarmony does not support creation of a Service Extension ability for third-party applications.
 
 
 ## How to Develop
 
-1. Create a Service Extension ability.
+1. Declare the Service Extension ability in the **module.json** file by setting its **type** attribute to **service**. The following is a configuration example of the **module.json** file:
 
-Customize a class that inherits from **ServiceExtensionAbility** in the .ts file and override the lifecycle callbacks of the base class. The code sample is as follows:
 
-  ```js
-  import rpc from '@ohos.rpc'
-  class StubTest extends rpc.RemoteObject {
-    constructor(des) {
-          super(des);
-    }
-    onRemoteRequest(code, data, reply, option) {
-    }
-  }
-
-  class ServiceExt extends ServiceExtensionAbility {
-    onCreate(want) {
-      console.log('onCreate, want:' + want.abilityName);
-    }
-    onRequest(want, startId) {
-      console.log('onRequest, want:' + want.abilityName);
-    }
-    onConnect(want) {
-      console.log('onConnect , want:' + want.abilityName);
-      return new StubTest("test");
-    }
-    onDisconnect(want) {
-      console.log('onDisconnect, want:' + want.abilityName);

 1. Instantiate a **Locale** object.<br>
    Create a **Locale** object by using the **Locale** constructor. This method receives a string representing the locale and an optional [Attributes](../reference/apis/js-apis-intl.md) list. 
 
+   A **Locale** object consists of four parts: language, script, region, and extension, which are separated by using a hyphen (-).
+   -  Language: mandatory. It is represented by a two-letter or three-letter code as defined in ISO-639. For example, **en** indicates English and **zh** indicates Chinese.
+   -  Script: optional. It is represented by a four-letter code as defined in ISO-15924. The first letter is in uppercase, and the remaining three letters are in lowercase. For example, **Hant** represents the traditional Chinese, and **Hans** represents the simplified Chinese.
+   -  Country or region: optional. It is represented by two-letter code as defined in ISO-3166. Both letters are in uppercase. For example, **CN** represents China, and **US** represents the United States.
+   -  Extensions: optional. Each extension consists of two parts, key and value. Currently, the extensions listed in the following table are supported (see BCP 47 Extensions). Extensions can be in any sequence and are written in the format of **-key-value**. They are appended to the language, script, and region by using **-u**. For example, **zh-u-nu-latn-ca-chinese** indicates that the Latin numbering system and Chinese calendar system are used. Extensions can also be passed via the second parameter.

 Use **OffscreenCanvasRenderingContext2D** to draw rectangles, images, and text offscreen onto a canvas. Drawing offscreen onto a canvas is a process where content to draw onto the canvas is first drawn in the buffer, and then converted into a picture, and finally the picture is drawn on the canvas. This process increases the drawing efficiency.

 # hapsigner Guide
 
-## Overview
-
-### Function
-To ensure the integrity and secure source of OpenHarmony applications, the applications must be signed during the build process. Only signed applications can be installed, run, and debugged on real devices. [developtools_hapsigner](https://gitee.com/openharmony/developtools_hapsigner) provides the source code of the OpenHarmony Ability Package (HAP) signing tool - hapsigner. This tool can be used to generate key pairs, certificate signing requests (CSRs), certificates, profile signatures, and HAP signatures.
-
-
-### Key Concepts
-
-The hapsigner tool is implemented based on the Public Key Infrastructure (PKI). Before using this tool, you should understand the following concepts:
-
- - Asymmetric key pair
-
-    The asymmetric key algorithm is the basis of data signature and signature verification. The hapsigner tool can generate standard asymmetric key pairs, including ECC P384/256 and RSA 2048/3072/4096.
-
- - CSR
-
-    The CSR contains the public key, subject, and private key signature of a certificate. Before applying for a certificate, you must generate a CSR based on the key pair and submit the CSR to the Certificate Authority (CA).
- - Certificate
-
-    OpenHarmony uses the RFC5280 standard to build the X.509 certificate trust system. The OpenHarmony certificates used for application signatures are classified into the root CA certificate, intermediate CA certificate, and end-entity certificate (application or profile signing certificate). The application signing certificate indicates the identity of the application developer, which ensures the traceability of the source of the applications. The profile signing certificate is used to verify the signature of the profile, which ensures the integrity of the profile.
-
- - HAP
-
-    HAP is a package used to deploy an ability, which is the basic unit for OpenHarmony application development. An OpenHarmony application consists of one or more abilities.
-
- - Profile
-
-    The profile in a HAP contains information such as the authorized certificate permission and device ID.
-
-### Constraints
-
- - hapsigner is developed in Java and must run in JRE 8.0 or later.
-
- - The scripts, such as the one-click signature script, are developed in Python, and must run on Python 3.5 or later.
-
-

 4. Sign the HAP.
 
 
-> **Precautions** <br/>
+> **Precautions** <br>
 >
-> For security purposes, the ECC algorithm is recommended for generating key pairs for application signing signatures. The RSA algorithm is not recommended.<br/>
->  You are advised to place the HAP, profile, KS file **OpenHarmony.p12**, root CA certificate, intermediate CA certificate, and hapsigner in the same directory for easy operation.
->  The [**developtools_hapsigner/autosign/result**](https://gitee.com/openharmony/developtools_hapsigner/tree/master/autosign/result) directory has the following files:<br/>-&nbsp;OpenHarmony KS file **OpenHarmony.p12** <br/>-&nbsp;Root CA certificate **rootCA.cer**<br/>-&nbsp;Intermediate CA certificate **subCA.cer**<br/>-&nbsp;Profile signing certificate **OpenHarmonyProfileRelease.pem**
-
-
-**1. Generate a key pair for the application signing certificate.**
-
-Generate a signature key pair and save it to the KS.
-
-Example:
-```shell
-java -jar hap-sign-tool.jar generate-keypair -keyAlias "oh-app1-key-v1" -keyAlg "ECC"  -keySize "NIST-P-256" -keystoreFile "OpenHarmony.p12" -keyPwd "123456" -keystorePwd "123456"
-```
-  > ![icon-note.gif](../public_sys-resources/icon-note.gif) **NOTE**<br/>Record the values of **keyAlias**, **keyStorePwd**, and **keyPwd**. These values will be used when the application signing certificate is generated and the HAP is signed.
-
-The command parameters are described as follows:
-
-      generate-keypair: Generate a key pair for the application signing certificate.
-          ├── -keyAlias         # Alias of the key used to generate the application signing certificate. It is stored in the OpenHarmony.p12 file. This parameter is mandatory.

+# hapsigner Overview
+
+## Introduction
+
+To ensure the integrity and secure source of OpenHarmony applications, the applications must be signed during the build process. Only signed applications can be installed, run, and debugged on real devices. [developtools_hapsigner](https://gitee.com/openharmony/developtools_hapsigner) provides the source code of the OpenHarmony Ability Package (HAP) signing tool - hapsigner. This tool can be used to generate key pairs, certificate signing requests (CSRs), certificates, profile signatures, and HAP signatures.
+
+## Basic Concepts
+
+The hapsigner tool is implemented based on the Public Key Infrastructure (PKI). Before using this tool, you should understand the following concepts:
+
+ - Asymmetric key pair
+
+   The asymmetric key algorithm is the basis of data signature and signature verification. The hapsigner tool can generate standard asymmetric key pairs, including ECC P384/256 and RSA 2048/3072/4096.
+
+ - CSR
+
+   The CSR contains the public key, subject, and private key signature of a certificate. Before applying for a certificate, you must generate a CSR based on the key pair and submit the CSR to the Certificate Authority (CA).
+
+ - Certificate
+
+   OpenHarmony uses the RFC5280 standard to build the X.509 certificate trust system. The OpenHarmony certificates used for application signatures are classified into the root CA certificate, intermediate CA certificate, and end-entity certificate (application or profile signing certificate). The application signing certificate indicates the identity of the application developer, which ensures the traceability of the source of the applications. The profile signing certificate is used to verify the signature of the profile, which ensures the integrity of the profile.
+
+ - HAP
+
+   HAP is a package used to deploy an ability, which is the basic unit for OpenHarmony application development. An OpenHarmony application consists of one or more abilities.
+
+ - Profile
+
+   HarmonyAppProvision configuration file in a HAP contains information such as the authorized application permissions and device ID.
+
+## Constraints
+
+ - hapsigner is developed in Java and must run in JRE 8.0 or later.
+
+ - The scripts, such as the one-click signature script, are developed in Python, and must run on Python 3.5 or later.

+
+1. For details about the mapping between the app's ability privilege level (APL) and permission level, see [Permission Levels](accesstoken-overview.md#permission-levels).
+2. Permissions can be authorized by the user (user_grant) or the system (system_grant). For details, see [Permission Authorization Modes](accesstoken-overview.md#permission-authorization-modes).
+3. In principle, an app with a lower APL cannot apply for higher permissions by default. The Access Control List (ACL) makes low-level apps have high-level permissions. For details, see [ACL](accesstoken-overview.md#acl).

+| Parameter | Description |
+| ----------- | ---------------- |
+| -a | Samples all processes and threads in the system. |
+| --exclude-hiperf | Leaves the hiperf process not sampled. |
+| -c | Specifies the IDs of the CPUs to sample. |
+| --cpu-limit&nbsp;&lt;_percent_&gt; | Specifies the maximum percentage of CPU resources occupied by the sampling. |
+| -d&nbsp;&lt;sec&gt; | Specifies the sampling duration, in seconds. |
+| -f&nbsp;&lt;freq&gt; | Specifies how often a sampling event is triggered. The default value is 4000 times/second. <br>Note: <br>A higher value indicates heavier CPU load but more sampling data. |
+| --period&nbsp;&lt;_num_&gt; | Specifies the number of occurrence times of an event that triggers a sampling. That is, a sampling is performed once when the event occurs the specified number of times. |
+| -e | Specifies the events to monitor. You can run the list command to list all the events supported. **event:u** indicates an event in the user space, and **event:k** indicates an event in the kernel space. |
+| -g | Specifies a group of events to monitor. The events in the same group are monitored by the same PMU. |
+| --no-inherit | Leaves the sub-threads of the target thread or process not monitored. |
+| -p | Specifies the processes to monitor. |
+| -t | Specifies the threads to monitor. |
+| --offcpu | Monitors the CPU scheduling event, which is equivalent to the **--period 1 -e sched:sched_switch** event. |
+| -j&nbsp;&lt;_branch_filter1_&gt;[,_branch_filter2_]... | Monitors the branch prediction events. Branch prediction tries to predict the next instruction to be executed if there are multiple if else conditions. |
+| -s&nbsp;/&nbsp;--call-stack&nbsp;&lt;_fp&nbsp;\\|&nbsp;dwarf[,size]_&gt; | Sets the user stack unwinding mode, which can be **fp** or **dwarf**. If **dwarf** is used, you can specify the size of the user stack to be sampled. The default value is **65528**. |
+| --delay-unwind | Delays the stack unwinding till the sampling is complete. |
+| --disable-unwind | Disables stack unwinding. The user register and stack data is stored in **perf.data** for offline stack unwinding. |
+| --disable-callstack-expend | Disables the unwound call stack information from being combined or extended. |
+| --clockid&nbsp;&lt;_clock&nbsp;type_&gt; | Sets the clock source for the sampling data. The options are **monotonic**, **boottime**, and **realtime**. |
+| --symbol-dir&nbsp;&lt;_dir_&gt; | Specifies the directory of the symbol table. The specified symbol table will be preferentially used in stack unwinding. |
+| -m&nbsp;&lt;_mmap&nbsp;pages_&gt; | Specifies the cache size, in pages. The default value is **1024**. The parameter value must be a power of 2. The value range is [2 - 1024].<br>Note: <br>A higher value indicates a lower event loss rate but higher memory usage. |
+| --app&nbsp;&lt;_package&nbsp;name_&gt; | Specifies the bundle name of the target application to be sampled. The default timeout interval is 10 seconds. If the specified application does not exist, the hiperf process exits after 10 seconds. |
+| --data-limit&nbsp;&lt;_SIZE[K\|M\|G]_&gt; | Specifies the maximum size of the sampling result, in KB, MB, or GB. By default, there is no limit on the size. |
+| -o&nbsp;&lt;_output&nbsp;file&nbsp;name_&gt; | Specifies the name of the sampling result file. It is **/data/local/tmp/perf.data** by default. |
+| -z | Saves the output file in .gzip format. |
+| --verbose | Displays detailed log information during sampling. |

+The USB service architecture consists of three layers:
 - USB API: a layer that provides JS APIs for the upper layer through NAPI.
 
-- USB Service: a layer implemented by using the C++ programming language and logically divided into the Host, Device, and Port modules. HDI-based APIs provided by USB Service are mainly used to implement management of USB device list, USB functions, USB ports, and USB device access permissions.

-**Problem**
+**Symptom**
 
 When the LiteOS Cortex-A kernel \(Hi3516 or Hi3518 platform\) directly calls the API provided by the KV store, the compiled executable program fails to run.
 
 **Possible Causes**
 
-The compiled executable program is run directly without being converted to an application using  **AbilityKit**  APIs. In this case, the Bundle Manager Service \(BMS\) cannot correctly set the path for storing application data during application installation. As a result, the KV store fails to run.
