This tutorial covers common use cases for configuration splits as a strategy for configuration management in Drupal 8.

Specifically it covers:

• Default application configuration
• Environment specific configuration (e.g., local, data, test, prod, etc.)
• Site-specific configuration (when multisite is used)
• "Feature" specific configuration (e.g. a distinct blog feature that is shared across multiple sites). Not to be confused with the features module.
• Miscellaneous troubleshooting information

Pull Request Etiquette

Why do we use a Pull Request workflow?

PRs are a great way of sharing information, and can help us be aware of the changes that are occuring in our codebase. They are also an excellent way of getting peer review on the work that we do, without the cost of working in direct pairs.

Ultimately though, the primary reason we use PRs is to encourage quality in the commits that are made to our code repositories

Done well, the commits (and their attached messages) contained within tell a story to people examining the code at a later date. If we are not careful to ensure the quality of these commits, we silently lose this ability.

Sometimes a Controller is Just a Controller

Abstract

You grok SOLID. You practice TDD. You've read Sandi's book…twice. You rewatch Destroy All Software monthly. You can pronounce GOOS. You know your stuff!

But some of your coworkers say your code is too complex or confusing for them. You might rush to conclude that must be a them problem.

But doubt lingers: what if they're right?

Creating a Happy Git Environment on OS X

Step 1: Install Git

brew install git bash-completion

Configure things:

git config --global user.name "Your Name"

git config --global user.email "you@example.com"

#!/usr/bin/env bash

if [ $EUID -ne 0 ]; then
    echo "You must be root: \"sudo ngxdis\""
    exit 1
fi

# -z str: Returns True if the length of str is equal to zero.
if [ -z "$1" ]; then
    echo "Please choose a site."

Nginx FastCGI response buffer sizes

By default when Nginx starts receiving a response from a FastCGI backend (such as PHP-FPM) it will buffer the response in memory before delivering it to the client. Any response larger than the set buffer size is saved to a temporary file on disk. This process is outlined at the Nginx ngx_http_fastcgi_module page document page.

• Introduction
• Determine actual FastCGI response sizes
• Setting the buffer size
• Verifying results

Introduction

Since disk is slow and memory is fast the aim is to get as many FastCGI responses passing through memory only. On the flip side we don't want to set an excessively large buffer as they are created and sized on a per request basis (i.e. it's not shared memory).
