2. To the repositories section:

   {
        "type": "git",

   }
   

3. Run composer update

4. Add this module to the project configuration list:

   $config['modules']['shellTask'] = ['class' => 'idfly\shellTask\Module'];

Description

The module provides an abstract class idfly\ShellTask with functions for launching and checking the yii2 console command status.

The command may be run in asynchronously or in blocking mode.

Method run() takes 2 arguments: $task and $options.

Argument $task contains yii2 console command name, for example subscribers/send-forecast-email.

Argument $options is an array with some fields (all fields are optional):

• timeout - type int, is a limit on execution time in seconds;

• memoryLimit - type string, is a limit for memory, has a format a like php-commands, for example 128M;

• args - type array, the arguments for yii-command;

• appendToLogs - type bool, is an opportunity to append command`s log-file without file rewriting;

• concurrent - type bool, command launching asynchronously;

The status of the task is checked by method getInfo(), which takes 2 arguments: task and optional taskId.

getInfo() return the array with following fields:

• log - log-file text;

• status_code - shell-code of the task completion;

• is_running - in blocking call will show whether the command is executing at the moment;

• processes_count - if there is an taskId argument the field will contain the number of asynchronous processes executing at the moment;

While using concurrent option, the method run() returns task ID;

Example

1. Run the task with a limit on execution time and memory:

    $options = [
        'timeout' => 10,
        'memoryLimit' => '128M',
    ];
   
    ShellTask::run('wares/update-similar', $options);
   

2. Get a result of the command execution:

    $result = ShellTask::getInfo('wares/update-similar');
   

3. Run two tasks asynchronously:

    $options = [
        'concurrent' => true,
        'args' => [
            '1',
        ]
    ];
   
    $taskOneId = ShellTask::run('do/something', $options);
   
    $options = [
        'concurrent' => true,
        'args' => [
            '2',
        ]
    ];
   
    $taskTwoId = ShellTask::run('do/something', $options);
   

4. Take result of first command from paragraph 3 execution:

    $result = ShellTask::getInfo('do/something', $taskOneId);
