3.x - 'PANTHEON_ENVIRONMENT' Is Not Detected from the Environment

Problem/Motivation

The 3.x version of this module appears to rely on Pantheon's prepend script to supply the environment as a constant. Without this, search is broken.

<!--break-->

I know that the project page says that all versions before 8.x are now obsolete, but for those of us who are still running Solr 3.6 on Pantheon (especially since Solr 8.x isn't yet officially supported for local development on Lando), we're stuck. With that in mind, in the 3.x version of this module, it looks like \Drupal\search_api_pantheon\Solarium\PantheonCurl::createHandle() only detects the Pantheon environment if it has been provided as a constant (i.e., it uses defined('PANTHEON_ENVIRONMENT')), rather than picking it up from environment variables. The rest of the module uses $_ENV['PANTHEON_ENVIRONMENT'], leading to inconsistent behavior among components in the same project.

It appears that the constant is normally provided by a PHP prepend file, /srv/includes/prepend.php that is loaded via auto_prepend_file = '/srv/includes/prepend.php' in the system-default php.ini file. This is not an issue on Pantheon itself but is an issue for local development on Lando if you are using a custom PHP config for XDEBUG support.

Steps to reproduce

  1. Create a Pantheon-based Drupal site, if you don't have one.
  2. Follow the Quick Start instructions to create a new Lando project from the Drupal site.
  3. Create a blank custom php.ini file under you project, located under .lando/php.ini.
  4. Modify your .lando.yml so that it includes the following section:
    services:
  appserver:
    config:
      php: .lando/php.ini
  5. Install the Search API Pantheon 3.x module and its dependencies via Composer.
  6. Start the Lando app.
  7. Enable the Search API Pantheon module.
  8. Attempt to create a new Search API server that uses the Pantheon Solr connector.

With this configuration, on the /admin/config/search/search-api/server/YOUR_SERVER_NAME page, you will get the following errors:

  • "The Solr server could not be reached or is protected by your service provider."
  • "The Solr core could not be accessed. Further data is therefore unavailable."

When performing searches, you will get 404 errors as status messages:

Proposed resolution

\Drupal\search_api_pantheon\Solarium\PantheonCurl::createHandle() should be modified to detect the Pantheon environment using $_ENV['PANTHEON_ENVIRONMENT'].
