ErrorHeroModule : a Hero for Your Zend Mvc and Expressive Application

Posted in expressive, Teknologi, Zend Framework, Zend Framework 2, Zend Framework 3 by samsonasik on December 20, 2017

After > 1 year work with 52 releases, I think it is time to show off. Even you have 100% test coverage, error may can still happen, that’s why ErrorHeroModule was born. ErrorHeroModule is a Hero for your Zend Mvc, and zend-expressive application to trap php errors and exception with configureable options.

The logging storage is mainly a database, then can continue “log” to your email when you want it.

Features

1. Save to DB with Db Writer Adapter

We can choose using Zend\Db or Doctrine via DoctrineORMModule. The error log is recorded like below:

2. Log Exception (dispatch.error and render.error) and PHP Errors in all events process

This handle all Exceptions and Errors with support PHP 7 Error during MVC process or middleware flow.

3. Support excludes PHP E_* Error (eg: exclude E_USER_DEPRECATED) in config settings

This can be used when you have a functionality which has collection of E_* errors, and you need to keep the functionality to run.

4. Support excludes PHP Exception (eg: Exception class or classes that extends it) in config settings

This can be used when you have exceptions that you want to have special treatment.

5. Handle only once log error for same error per configured time range

This can be used when on some environment, eg: in production, we don’t want to get same error repeatly reported in some periodic time while we are fixing it.

6. Set default page (web access) or default message (console access) for error if configured ‘display_errors’ = 0

This can be used to set a “nice” page on web environment:

or content on console access:

7. Set default content when request is XMLHttpRequest via ‘ajax’ configuration

This can be used to set a default content when request is an XMLHttpRequest.

8. Provide request information ( http method, raw data, query data, files data, and cookie data )

This can be used to help reproduce the error.

9. Send Mail

This has options:
– many receivers to listed configured email
– with include $_FILES into attachments on upload error.

This can be used to help reproduce the error, with include uploaded data when error happen when we just submitted a form with upload process.

Support

This module support zend-mvc:^2.5 and zend-expressive:^1.1|^2.0 with php version ^5.6|^7.0. My plan is to drop php ^5.6 in version 2.

Limitations

There are some limitations right now and I want it to be implemented in next releases:

General functionality:

  • Allow custom formatter when log to email, currently, it send Json format to email.

Current Json Formatter is really stable with the following format sample data:

{
    "timestamp": "2017-12-20T15:23:00+07:00",
    "priority": 3,
    "priorityName": "ERR",
    "message": "a sample error preview",
    "extra": {
        "url": "http://app.dev/error-preview",
        "file": "/var/www/app/vendor/samsonasik/error-hero-module/src/Controller/ErrorPreviewController.php",
        "line": 11,
        "error_type": "Exception",
        "trace": "#0 /var/www/app/vendor/zendframework/zend-mvc/src/Controller/AbstractActionController.php(78): ErrorHeroModule\\Controller\\ErrorPreviewController->exceptionAction()
#1 /var/www/app/vendor/zendframework/zend-eventmanager/src/EventManager.php(322): Zend\\Mvc\\Controller\\AbstractActionController->onDispatch(Object(Zend\\Mvc\\MvcEvent))
#2 /var/www/app/vendor/zendframework/zend-eventmanager/src/EventManager.php(179): Zend\\EventManager\\EventManager->triggerListeners(Object(Zend\\Mvc\\MvcEvent), Object(Closure))
#3 /var/www/app/vendor/zendframework/zend-mvc/src/Controller/AbstractController.php(106): Zend\\EventManager\\EventManager->triggerEventUntil(Object(Closure), Object(Zend\\Mvc\\MvcEvent))
#4 /var/www/app/vendor/zendframework/zend-mvc/src/DispatchListener.php(138): Zend\\Mvc\\Controller\\AbstractController->dispatch(Object(Zend\\Http\\PhpEnvironment\\Request), Object(Zend\\Http\\PhpEnvironment\\Response))
#5 /var/www/app/vendor/zendframework/zend-eventmanager/src/EventManager.php(322): Zend\\Mvc\\DispatchListener->onDispatch(Object(Zend\\Mvc\\MvcEvent))
#6 /var/www/app/vendor/zendframework/zend-eventmanager/src/EventManager.php(179): Zend\\EventManager\\EventManager->triggerListeners(Object(Zend\\Mvc\\MvcEvent), Object(Closure))
#7 /var/www/app/vendor/zendframework/zend-mvc/src/Application.php(332): Zend\\EventManager\\EventManager->triggerEventUntil(Object(Closure), Object(Zend\\Mvc\\MvcEvent))
#8 /var/www/app/public/index.php(53): Zend\\Mvc\\Application->run()
#9 {main}",
        "request_data": {
            "query": [],
            "request_method": "GET",
            "body_data": [],
            "raw_data": "",
            "files_data": [],
            "cookie_data": {
                "ZS6SESSID": "pbihc9ts004oq4b5alg4tg91b6",
                "PHPSESSID": "bkd7jaj22z936vstc9l0xuc9sr2dqp4g",
            }
        }
    }
}

The drawback with allow custom formatter is you maintain/keep an eye yourself for the formatter you provide!

Zend Mvc application:

  • Trap exception and error when they happen at Module::init().

Zend Expressive application:

  • Make support for non zend-servicemanager for container.
  • Make support for non zend-view for custom page template engine when error happen. (supported at version 2.1.0)

That’s it for now. If you see something can be improved, please contribute! Thank you for all users that using it.
