1# Job Management 2## Overview 3### Function 4A job is a set of commands in the **.cfg** file of the init module. A maximum of 4096 jobs can be added. Jobs can be configured in the [.cfg file](subsys-boot-init-cfg.md). Generally, jobs are executed during initialization to serve the normal startup of services or the initialization of specific basic functions. 5 6### Basic Concepts 7A job can be configured in the **init.cfg** file or the custom **.cfg** file of the module. The parser of the init process aggregates commands of the jobs with the same name into one job. For jobs with the same name, the init process only ensures that the commands in the **init.cfg** file are executed in preference. It does not guarantee the execution sequence of commands in other **.cfg** files. 8- Common job 9 10 A job executed in a fixed phase during init process startup, for example, pre-init, init, or post-init. 11 - pre-init: pre-initialization phase. Key services on which other services depend, such as ueventd, watchdog, and hilogd, are started in this phase. The mounting of data partitions is also done in this phase. 12 - init: main phase of the initialization process. In this phase, a large number of commands are executed, and services in the **boot** group (first group) are started concurrently by the **init** group. Some important services related to system functions are also started in this phase. 13 - post-init: post-initialization phase. In this phase, the **trigger** command is used to invoke the execution of other phases, which can be regarded as independent phases, or the post-init phase as a whole. In this phase, a large number of commands are executed, and the **normal** group (the second group) is started by the **init** group. Most services configured in the **.cfg** files are started in this phase. 14 15- Custom job (for standard system or higher) 16 17 A job triggered based on specific rules. You can add commands to the job as required and run the **trigger** command to invoke the execution of commands in the job. 18 19- Conditional job (for standard system or higher) 20 21 A job triggered based on specific conditions. You can add conditions to a job so that the job is executed when the conditions are met. 22 23 A condition is a combination of system parameter values and supports operations such as **&&** and **||**, for example, **"condition": "sys.usb.config = none && sys.usb.configfs = 0"**. When defining commands for a job, you can add attributes in the format of **param:xxx** to form different commands. 24 25### Constraints 26With the system parameter module, the standard system is able to support basic, conditional, and custom jobs. The small system supports only basic jobs. 27 28## How to Develop 29### Use Cases 30A job is a command set, where you can manage the commands to be executed. A maximum of 4096 commands can be added to a command set. During the init startup process, the execution of jobs helps ensure normal running of services. 31 32### Parameters 33 34 **Table 1** Command set description 35<table border="0" cellpadding="0" cellspacing="0" width="770" style="border-collapse: collapse;table-layout:fixed;width:578pt;border-spacing: 0px;font-variant-ligatures: normal; font-variant-caps: normal;orphans: 2;text-align:start;widows: 2;-webkit-text-stroke-width: 0px; text-decoration-thickness: initial;text-decoration-style: initial;text-decoration-color: initial"> 36 <tbody> 37 <tr height="39" style="height:18.0pt"> 38 <th height="24" class="xl6521952" width="140" style="height:18.0pt;width:105pt"> 39 Command 40 </td> 41 <th class="xl6521952" width="215" style="border-left:none;width:161pt"> 42 Format and Example 43 </td> 44 <th class="xl6521952" width="225" style="border-left:none;width:169pt"> 45 Description 46 </td> 47 <th class="xl6521952" width="190" style="border-left:none;width:143pt"> 48 Supported System Type 49 </td> 50 </tr> 51 <tr height="231" style="height:173.25pt"> 52 <td height="231" class="xl6621952" width="140" style="height:173.25pt;border-top: none;width:105pt"> 53 mkdir 54 </td> 55 <td class="xl6621952" width="215" style="border-top:none;border-left:none; width:161pt"> 56 mkdir <i>target folder</i> [mode] [owner] [group]<br>Example:<br>mkdir /storage/myDirectory<br>mkdir /storage/myDirectory 0755 root root 57 </td> 58 <td class="xl6621952" width="225" style="border-top:none;border-left:none; width:169pt"> 59 Creates a folder. <strong>mkdir</strong> and the target folder must be separated by only one space.

The following describes the job management APIs. 672 673**Table 2** Description of job parsing APIs 674<table border="0" cellpadding="0" cellspacing="0" width="968" style="border-collapse: collapse;table-layout:fixed;width:727pt;orphans: 2;widows: 2;-webkit-text-stroke-width: 0px; text-decoration-thickness: initial;text-decoration-style: initial;text-decoration-color: initial; box-sizing: border-box;border-spacing: 0px;word-break:initial;font-variant-ligatures: normal; font-variant-caps: normal"> 675 <tbody> 676 <tr height="39" style="height:29.25pt;box-sizing: border-box"> 677 <th height="39" class="xl6320252" width="249" style="height:29.25pt;width:187pt"> 678 API 679 </th> 680 <th class="xl6420252" width="235" style="width:176pt;border-image: initial"> 681 Input Parameter 682 </th> 683 <th class="xl6420252" width="106" style="width:80pt;border-image: initial"> 684 Return Value 685 </th> 686 <th class="xl6420252" width="200" style="width:150pt;border-image: initial"> 687 Description 688 </th> 689 <th class="xl6520252" width="170" style="width:134pt;border-image: initial"> 690 Supported System Type 691 </th> 692 </tr> 693 <tr height="99" style="mso-height-source:userset;height:74.25pt;box-sizing: border-box"> 694 <td height="99" class="xl6620252" width="249" style="height:74.25pt;width:187pt; border-image: initial;box-sizing: border-box"> 695 void ParseAllJobs(const cJSON *fileRoot) 696 </td> 697 <td class="xl6720252" width="235" style="width:176pt;border-image: initial; box-sizing: border-box"> 698 const cJSON *fileRoot 699 </td> 700 <td class="xl6720252" width="106" style="width:80pt;border-image: initial; box-sizing: border-box"> 701 void 702 </td> 703 <td class="xl6720252" width="200" style="width:150pt;border-image: initial; box-sizing: border-box"> 704 Provides the general entry for parsing jobs. 705 </td> 706 <td class="xl6720252" width="170" style="width:134pt;border-image: initial; box-sizing: border-box"> 707 Small and standard systems 708 </td> 709 </tr> 710 <tr height="147" style="mso-height-source:userset;height:110.25pt;box-sizing: border-box"> 711 <td height="147" class="xl6820252" width="249" style="height:110.25pt;width:187pt; border-image: initial;box-sizing: border-box"> 712 static void ParseJob(const cJSON <span style="mso-spacerun:yes"> </span>*jobItem, Job *resJob) 713 </td> 714 <td class="xl6920252" width="235" style="width:176pt;border-image: initial; box-sizing: border-box"> 715 const cJSON *jobItem, Job *resJob 716 </td> 717 <td class="xl6920252" width="106" style="width:80pt;border-image: initial; box-sizing: border-box"> 718 void 719 </td> 720 <td class="xl7020252" width="200" style="width:150pt;border-image: initial; box-sizing: border-box"> 721 Checks whether a job exists and parses <strong>cmds</strong> in it. 722 </td> 723 <td class="xl6920252" width="170" style="width:134pt;border-image: initial; box-sizing: border-box"> 724 Small system 725 </td> 726 </tr> 727 <tr height="177" style="mso-height-source:userset;height:132.75pt;box-sizing: border-box"> 728 <td height="177" class="xl6620252" width="249" style="height:132.75pt;width:187pt; border-image: initial;box-sizing: border-box"> 729 int GetCmdLinesFromJson(const cJSON *root, CmdLines **cmdLines) 730 </td> 731 <td class="xl6720252" width="235" style="width:176pt;border-image: initial; box-sizing: border-box"> 732 const cJSON *root, CmdLines **cmdLines 733 </td> 734 <td class="xl6720252" width="106" style="width:80pt;border-image: initial; box-sizing: border-box"> 735 int 736 </td> 737 <td class="xl6720252" width="200" style="width:150pt"> 738 Parses <strong>cmds</strong> in the job.

You can use it to verify the job management function. 908``` 909{ 910 "jobs" : [{ // Basic job 911 "name" : "stage1", 912 "cmds" : [ 913 "start service1", 914 "mkdir dir1" 915 ] 916 }, { // Conditional job 917 "name" : "param:test.name1=0", 918 "condition" : "test.name1=0", 919 "cmds" : [ 920 "chmod 0755 dir1", 921 "chown root root dir1" 922 ] 923 }, { // Custom job 924 "name" : "param:test.name2=*", 925 "condition" : "test.name2=*", 926 "cmds" : [ 927 "chmod 0644 dir1", 928 "chown system system dir1" 929 ] 930 } 931 ] 932} 933``` 934The differences in job configuration are described as follows: 935 9361. <strong>name</strong> and <strong>cmds</strong> are mandatory for a job, and <strong>cmds</strong> must contain commands supported by the system. 937 9382. <strong>condition</strong> is an optional attribute of a job. It indicates that the job is triggered only when the specified condition is met; that is, the job will not be invoked in a specific phase by the code or the <strong>trigger</strong> command. 939 9403. The job name must comply with the specified rules. For a job whose condition is a system parameter, its name is prefixed with <strong>param:</strong>. 941 9424. Commands in a renamed job can be executed only after being triggered by the <strong>trigger</strong> command in other executable job command groups. By default, the <strong>trigger</strong> command is executed in the post-init phase. 943 9445. An existing job name can be used in different files. Jobs with the same name are regarded as the same job. When jobs with the same name are executed, the commands in these jobs are executed together. 945 9466. For a conditional job, a condition is usually a system parameter. You can set a specific value so that the job is triggered when the condition is met. You can also set the value to an asterisk (*) so that the job is triggered whenever the condition is met, regardless of the parameter value. 947 9487. For the small system, the commands in a job cannot be triggered by the <strong>trigger</strong> command in the post-init phase. 949
