Magento 2 Cache Cheat Sheet

This page lists what caches or directories you will need to clear to apply various types of changes. It is consolidated and adapted from the complete official documentation on directories and caches.

💁 If your development environment supports it, you are better off using Vinai's automatic cache cleaner. As of this writing, the primary reason why it might not work is if your code is hosted on a NFS share (common with Vagrant).

Purpose

Reformat Jira ticket export to include comments in the ticket description and to update attachment URLs to include an authorization key.

Background

Jira provides the ability to import from CSV two different ways:

1. External System Import: A more powerful import accessible only to admins and that is potentially too powerful, auto-creating users and custom fields in a way that may not be desired.

Guide to Resetting a csync2 Cluster

Introduction

These are possible steps to reset a csync2 cluster that has been seriously fubared. This is an apocalyptic approach and should only be used when more surgical fixes (like correcting an individual conflict) aren't workable.

PayPal API ID Prefix Formats

PayPal uses various prefixes to distinguish different types of unique IDs in their APIs, but these are not currently documented in a single place. This Gist seeks to bring that information together into a single place. If there is something missing, please reach out through one of the channels on my GitHub profile since GitHub doesn't send notifications on Gist comments.

The WooCommerce Authorize.net DPM plugin (v.1.8.0) has a bug in the SHA2 response calculation, causing the following error to appear to customers when they enter invalid credit card information (as well as an email to the merchant admin email):

An error occurred while trying to report this transaction to the merchant. An e-mail has been sent to the merchant informing them of the error. The following is the result of the attempt to charge your credit card.

As a quick fix, open the file class-wc-authorize-net-relay-response-handler.php and search for this bit of code:

! empty( $data[ $hash_field ] )

And replace with this:

#!/bin/bash

# Settings
SUFFIX=alt
MAGERUNCMD=magerun

# Sanity Checks
type $MAGERUNCMD >/dev/null 2>&1 || {
    echo "ERROR: This script requires the command '$MAGERUNCMD' to be executable in the current path."
    exit
