Experimental Add-on to use PHP patch versions: ddev-php-patch-build

DDEV users periodically ask if they can use a specific PHP patch version with their projects, either to test/compare for a particular bug or to match a production version exactly.

This experimental add-on tries to address that need, although there are a number of caveats:

1. The build done using this process uses the technique from static-php-cli and full details are available there. Currently it supports PHP 7.3-8.3.
2. The build does not match the build done using the official DDEV php packages (which actually come from deb.sury.org.
3. It currently does not provide xdebug, see extension support.
4. The resultant PHP binaries built here do not have the exact same extensions as the official DDEV PHP binaries.
5. Building the binaries happens in the build phase of ddev start, and it takes a long time on the first ddev start or whenever you change versions. My tests on Gitpod, with a great internet connection, took about 8-9 minutes. It can be really annoying, and a better way to build would be an improvement.
6. If you want to see the build process as it proceeds, you can use ddev debug refresh or DDEV_VERBOSE=true ddev start.
7. Your mileage may vary.

• The static-php-ci repository provides a relatively easy way to build static PHP binaries (the CLI and php-fpm) which can be used to replace the ones installed in ddev-webserver.
• The provided Dockerfile.php-patch-build does the building.
• The provided config.php-patch-build provides post-start hooks that install the built binaries.

Installation

1. ddev get rfay/ddev-php-patch-build

Components of the add-on

• config.php-yaml
• Dockerfile.php-patch-build
• A test suite in test.bats that makes sure the service continues to work as expected.
• Github actions setup so that the tests run automatically when you push to the repository.
