An MU Plugin that makes a few adjustments to make local development friendlier (for me).

• Clone this directory into wp-content/mu-plugins/must-use-local/
• Setup mu-plugins/index.php to load wp-content/mu-plugins/must-use-local/must-use-local.php somehow or copy the mu-autoloader.php file in this plugin to your mu-plugins/ directory.

• Disable SSL verification locally to avoid any annoying issues with self-signed certs for .test domains.
• Treat requests to local domains as external so that things like cron actually work.

• Increase session time for authenticated users to 365 days.

• Filter PHPMailer so that Mailhog is used to send (and capture) emails locally.

I want to be able to export a production database, set it up locally, and then adjust the display of Jetpack related posts without much hassle.

• Related posts does not work in development mode, so set that to false.
• Nothing should think it's in production, so enable staging mode.
• Except! When retrieving image URLs, Jetpack should think it's in development mode so that it doesn't use Photon.

When I configure a production database locally, I want to be able to run wp user update 123 --user_pass=password and immediately login to the site.

• Unhook Jetpack SSO locally so that no attempt to use WordPress.com to sign-in is made.

• Adds Xdebug related information to the Server section of the Site Health Info page.

This gist and this article include a LocalValetDriver.php file that when placed in the project root and configured properly will proxy remote images from a domain when they are not available locally.

I would include this file in the repo, but I can't find an explicit license, so copy it from one of those sources. :)
