Quick Start

You need to be able to access the customers in the database. The first 20 customers with ID from 1 to 20 are allowed to view the output in the browser. You can edit the entity_id in the table customer_entity for these users.

Debug Helper

Example uses of the helper:

// Add a log entry to file var/log/shooter.log:
Mage::helper('shooter')->log("string=$string", $var); // Log a message
Mage::helper('shooter')->trace('trace message'); // Trace the call stack

// To troubleshoot controllers:
return Mage::helper('shooter')->echoParams($var); // Display the request parameters, $var is optional
return Mage::helper('shooter')->echo($var, $title); // Display a variable, $title is optional

Output the Log Files in the Browser

URI /shooter/log

To output the recent entries of the log files in var/log/*.log and var/report/{latest file}:

{http://your_domain}/shooter/log

Optional parameters:

• ?lines=L, where L is the number of lines to display, default is 80.
• ?secs=S, where S is the number of seconds from the modification time beyond which the file will not be displayed, default is 80.

For example, to list the log files from the last 120 lines and modified in the last hour:

{http://your_domain}/shooter/log?lines=120&secs=3600

URI shooter/log/tail

To show exception.log:

{http://your_domain}/shooter/log/tail

Optional parameters:

• ?fnm=F, where F is the name of the file to display, default is exception.log.
• ?lines=L, where L is the number of lines to display, default is 80.
• ?dir=D, where D is the directory of the file to display, default is var/log.

Refer to LogController.php for more details.

Capture error_get_last()

To capture the last error, insert the following code in index.php, just before the last line Mage::run($mageRunCode, $mageRunType);:

// Insert this code before the last line `Mage::run($mageRunCode, $mageRunType);`
register_shutdown_function(function(){
    $err = error_get_last();
    if ($err && $err['type'] != E_WARNING) {
        $err['type'] = $err['type'] . ':' . array_search($err['type'], get_defined_constants(true)['Core']);
        $err['uri'] = $_SERVER['REQUEST_URI'] ?? $_SERVER['SCRIPT_NAME'];
        [$err['user'], $err['role']] = Mage::helper('shooter')->getSessionUser();
        Mage::getModel('core/flag', ['flag_code' => 'error_get_last'])
            ->loadSelf()
            ->setFlagData($err)
            ->save();
    }
});

The error captured is displayed with URI /shooter/log.

Show Information in the Browser

{http://your_domain}/shooter/info # Display PHP information
{http://your_domain}/shooter/info/ver # Display OpenMage version
{http://your_domain}/shooter/info/server # Display server information

Refer to InfoController.php for more details.

REST OAuth 1.0a Tester

The tester allows you to test the OpenMage REST API as a consumer interactively with a browser. Use the following URI to access it:

{http://your_domain}/shooter/rest

The OAuth credentials are only stored in the session and never saved anywhere else.

Refer to RestController.php for more details.

Test SSL Connection

For public accessible URLs, tools like SSL Labs may be preferred. But if the site is private or under development, this tester is useful:

{http://your_domain}/shooter/ssl?url={url}

Refer to SslController.php for more details.
