Magento: Clear all caches from command line

Magento clear all caches from command line, programatically from ssh. Clearing the caches is a must when you are making any configuration changes in your Magento website. Although you can always clear the cache from admin panel, sometimes for faster cleaning or unable to log into admin panel reason, it’s good to have a script which will clear all the caches in Magento.

Create a file in your Magento root and name it clearCache.php with the below code:

<?php
echo "Start Cleaning all caches at ... " . date("Y-m-d H:i:s") . "\n\n";
ini_set("display_errors", 1);

require 'app/Mage.php';
Mage::app('admin')->setUseSessionInUrl(false);
Mage::getConfig()->init();

$types = Mage::app()->getCacheInstance()->getTypes();

try {
    echo "Cleaning data cache... \n";
    flush();
    foreach ($types as $type => $data) {
        echo "Removing $type ... ";
        echo Mage::app()->getCacheInstance()->clean($data["tags"]) ? "Cache cleared!" : "There is some error!";
        echo "\n";
    }
} catch (exception $e) {
    die("[ERROR:" . $e->getMessage() . "]");
}

echo "\n";

try {
    echo "Cleaning stored cache... ";
    flush();
    echo Mage::app()->getCacheInstance()->clean() ? "Cache cleared!" : "There is some error!";
    echo "\n\n";
} catch (exception $e) {
    die("[ERROR:" . $e->getMessage() . "]");
}
?>

Make sure all the double quotes comes good in copy pasting.

You can now run this script by the command “php -f clearCache.php” from your magento root location in terminal and this will start clearing all the caches for you! Once done, it will confirm by the message “Cache cleared!” or giving error message if it fails.

Magento: Enable logs on API calls

There is no setting to enable/disable API calls in Magento, but you can do so by modifying a file which handles all the API calls and logging the requests in a custom log file. This is useful when you know that there are many API calls being requested by third party applications to your website but not sure what is actually being called, how many times, and at what day and time.

With that said, open the file: app/code/core/Mage/Api/Model/Server/Handler/Abstract.php
and find the function “call” which handles all the API calls. Scroll down the function and find the if block which says:

1
2
3
4
5
6
7
8
9
10
11
if (method_exists($model, $method)) {
        if (isset($methodInfo->arguments) && ((string)$methodInfo->arguments) == 'array') {
            return $model->$method((is_array($args) ? $args : array($args)));
        } elseif (!is_array($args)) {
            return $model->$method($args);
        } else {
            return call_user_func_array(array(&$model, $method), $args); 
        }       
} else {
        throw new Mage_Api_Exception('resource_path_not_callable');
}

and replace it with:

1
2
3
4
5
6
7
8
9
10
11
12
13
if (method_exists($model, $method)) {
        Mage::log($method, null, 'api.log'); //logs the method
        Mage::log($args, null, 'api.log'); //logs the arguments
        if (isset($methodInfo->arguments) && ((string)$methodInfo->arguments) == 'array') {
            return $model->$method((is_array($args) ? $args : array($args)));
        } elseif (!is_array($args)) {
            return $model->$method($args);
        } else {
            return call_user_func_array(array(&$model, $method), $args);
        }
} else {
        throw new Mage_Api_Exception('resource_path_not_callable');
}

Now you should have your var/log/api.log file filled with the “method” and “arguments” requested by third party systems on your server. This should help you in knowing what was requested and at what time in your new log file.

Magento Redis read error on connection

Magento read error on connection when using Redis. If you are using Redis as cache in Magento and read timeout is not specified, you may get this error. Below is how it looks in the error report.

The solution (atleast for us) was to add a read_timeout config option in app/etc/local.xml where you have configured Redis cache for Magento.
