Create a Linux Swap File

Swap is a space on a disk that is used when the amount of physical RAM memory is full. When a Linux system runs out of RAM, inactive pages are moved from the RAM to the swap space.

Swap space can take the form of either a dedicated swap partition or a swap file. In most cases, when running Linux on a virtual machine, a swap partition is not present, so the only option is to create a swap file.

This tutorial was tested on Linux systems with Ubuntu 18.04 and CentOS 7, but it should work with any other Linux distribution.

How to add Swap File

Follow these steps to add 1GB of swap to your server. If you want to add 2GB instead of 1 GB, replace 1G with 2G.

1. Create a file that will be used for swap:

sudo fallocate -l 1G /swapfile

If faillocate is not installed or if you get an error message saying fallocate failed: Operation not supported then you can use the following command to create the swap

file:

sudo dd if=/dev/zero of=/swapfile bs=1024 count=1048576

2. Only the root user should be able to write and read the swap file. To set the correct permissions type:
sudo chmod 600 /swapfile

3. Use the mkswap utility to set up the file as Linux swap area:

sudo mkswap /swapfile

4. Enable the swap with the following command:

sudo swapon /swapfile

To make the change permanent open the /etc/fstab file and append the following line:

/etc/fstab

/swapfile swap swap defaults 0 0

5. To verify that the swap is active, use either the swapon or the free command as shown below:
sudo swapon --show

Output

NAME      TYPE  SIZE   USED PRIO
/swapfile file 1024M 507.4M   -1

sudo free -h

What is interceptor or plugins in Magento 2?

Question : What is interceptor or plugins in Magento 2?

Plugins (Interceptors)

Basically plugin, or interceptor both are same. it is a class only which are modifies the behavior of public class functions by intercepting a functionality and running code before, after, or around that function call. This allows you to substitute or extend the behavior of original, public methods for any class or interface.

Extensions that wish to intercept and change the behavior of a public method can create a Plugin class.

This interception approach reduces conflicts among extensions that change the behavior of the same class or method. Your Plugin class implementation changes the behavior of a class function, but it does not change the class itself. Magento calls these interceptors sequentially according to a configured sort order, so they do not conflict with one another.

Plugins can not be used on following:

Final methods
Final classes
Non-public methods
Class methods (such as static methods)
__construct
Virtual types
Objects that are instantiated before Magento\Framework\Interception is bootstrapped

What is object manager in Magento 2?

ObjectManager

Object manager is Maento 2 core class a "Magento/Framework/ObjectManagerInterface".

Object manager to avoid boilerplate code when composing objects during instantiation.

In the Magento framework, the implementation of the ObjectManagerInterface performs the duties of an object manager.

Responsibilities :

The object manager has the following responsibilities:

1. Object creation in factories and proxies.
2. Implementing the singleton pattern by returning the same shared instance of a class when requested
3. Dependency management by instantiating the preferred class when a constructor requests its interface
4. Automatically instantiating parameters in class constructors

Remove precision from price of a product

 

0 down vote favorite

As I said in the title, I want to remove precision from price ( .00 ) I did these : In app/code/core/Mage/Directory/Model/Currency.php in public function format() I changed return $this->formatPrecision($price, 2, $options, $includeContainer, $addBrackets); to return $this->formatPrecision($price, 0, $options, $includeContainer, $addBrackets); In /app/code/core/Mage/Adminhtml/Block/Catalog/Product/Helper/Form/Price.php in public function getEscapedValue() I changed return number_format($value, 2, null, ''); to return number_format($value, 0, null, ''); In js/varien/js.js I changed var precision = isNaN(format.precision = Math.abs(format.precision)) ? 2 : format.precision; var requiredPrecision = isNaN(format.requiredPrecision = Math.abs(format.requiredPrecision)) ? 2 : format.requiredPrecision; to var precision = 0; var requiredPrecision = 0; And in app/code/core/Mage/Core/Model/Store.php I changed public function roundPrice($price) { return round($price, 2); } to public function roundPrice($price) { return round($price, 0); } Then I cleared the cache, and reindexed Magento (which is i version1.9), But the precision didn't remove, Am I missing something? what should I do?
