[#3112] Settled one environment variable guard form across the Drupal settings includes. - #3122
Conversation
… settings includes. Boolean flags are read with a strict comparison against '1', so every other value - unset, empty, '0', 'true' - leaves the behavior off. Value-carrying variables keep the '!empty()' presence check and are bound to a variable when the value is read again after the guard. Every comparison is strict. The contrib-presence guard now applies only where the include loads a file from the module directory or registers its paths, so 'settings.clamav.php' no longer checks for the module.
WalkthroughThe change standardizes environment variable handling across Drupal settings. Boolean flags now require exact values, value variables use non-empty checks, environment reads are cached, and tests cover invalid and empty inputs. ChangesEnvironment guard standardization

- Around line 1375-1376: Update the fixture setup in EnvironmentSettingsTest to
create .artifacts/tmp before assigning acquiaSettingsFixture and calling
file_put_contents. Ensure the directory exists on a clean checkout so the
fixture is written successfully and tearDown can remove it without warnings.
In `@web/sites/default/includes/providers/settings.acquia.php`:
- Line 67: Add migration guidance to the release notes or updating guide for
DRUPAL_TMP_PATH_IS_SHARED, instructing deployments using true to change the
value to 1. Preserve the exact-'1' check in the existing configuration logic.
