All modifications to contributed projects must be performed via a patch and must be applied via composer.json.
Drupal core and contrib can be patched in composer.json using cweagans/composer-patches, which is required by default. Patch information should be specified in the JSON array in accordance with the following schema:
"extra": {
"patches": {
"drupal/core": {
"Ignore front end vendor folders to improve directory search performance": "https://www.drupal.org/files/issues/ignore_front_end_vendor-2329453-116.patch"
}
}
},
Patches that can be contributed on Drupal.org should be contributed there. Please follow Drupal.org's patch naming conventions when creating patches.
Patches that cannot be contributed publicly are extremely rare. In the unlikely event that such a change must be committed, all project-specific patches should reside in this directory. This ensures one consistent place for patches and avoids accidental patch deletion. See instructions for using a local patch.
Patches should be stored in sub-directories based on project name being patched.
Examples:
- /patches/drupal/some_patch-1234-1.patch
- /patches/ctools/another_patch_name-9876-12.patch
