>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #3615405. --> Reported by: [mably](https://www.drupal.org/user/3375160) Related to !49 >>> <h3>Problem/Motivation</h3> <p>3.0.4 was tagged from the <code>3.x</code> branch, which had already moved to the domain 3.1 API in <span class="drupalorg-gitlab-issue-link drupalorg-gitlab-link-wrapper"><a href="https://git.drupalcode.org/project/domain_extras/-/work_items/3589272" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/domain_extras/-/work_items/3589272</a></span>. That release therefore requires <code>drupal/domain:^3.1.0-alpha4</code> and calls APIs that do not exist in domain 3.0, so a site running domain 3.0 can no longer install or update Domain Extras.</p> <p>The 3.1-only APIs involved are <code>DomainConfigUIManagerInterface::getActiveEditingDomainId()</code>, <code>Drupal\domain_access\Utility\DomainAccessFields</code> and <code>Drupal\domain_config_language\Config\DomainLanguageConfigCollectionUtils</code>.</p> <h3>Steps to reproduce</h3> <p>On a site with <code>drupal/domain:3.0.1</code>, run <code>composer require drupal/domain_extras:^3.0</code>. Composer resolves 3.0.4 and then refuses the domain constraint.</p> <h3>Proposed resolution</h3> <p>Keep 3.0.x on <code>drupal/domain:^3</code> and replay onto it only the post-3.0.3 commits that do not need the 3.1 API: <span class="drupalorg-gitlab-issue-link drupalorg-gitlab-link-wrapper"><a href="https://git.drupalcode.org/project/domain_extras/-/work_items/3592956" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/domain_extras/-/work_items/3592956</a></span>, <span class="drupalorg-gitlab-issue-link drupalorg-gitlab-link-wrapper"><a href="https://git.drupalcode.org/project/domain_extras/-/work_items/3613722" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/domain_extras/-/work_items/3613722</a></span>, <span class="drupalorg-gitlab-issue-link drupalorg-gitlab-link-wrapper"><a href="https://git.drupalcode.org/project/domain_extras/-/work_items/3613716" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/domain_extras/-/work_items/3613716</a></span> and <span class="drupalorg-gitlab-issue-link drupalorg-gitlab-link-wrapper"><a href="https://git.drupalcode.org/project/domain_extras/-/work_items/3613981" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/domain_extras/-/work_items/3613981</a></span>. Release 3.0.5 from 3.0.x.</p> <p>Leave <span class="drupalorg-gitlab-issue-link drupalorg-gitlab-link-wrapper"><a href="https://git.drupalcode.org/project/domain_extras/-/work_items/3589272" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/domain_extras/-/work_items/3589272</a></span> out of 3.0.x, and leave out the Domain Config Switcher submodule (<span class="drupalorg-gitlab-issue-link drupalorg-gitlab-link-wrapper"><a href="https://git.drupalcode.org/project/domain_extras/-/work_items/3592820" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/domain_extras/-/work_items/3592820</a></span>, <span class="drupalorg-gitlab-issue-link drupalorg-gitlab-link-wrapper"><a href="https://git.drupalcode.org/project/domain_extras/-/work_items/3592980" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/domain_extras/-/work_items/3592980</a></span>) too: it is built on <code>DomainConfigEditContext</code>, which domain 3.0 does not have, because there the domain whose configuration is edited is always the negotiated domain.</p> <p>Release the current 3.x tip as 3.1.0-alpha1 for sites on domain 3.1, and unpublish 3.0.4.</p> <h3>Remaining tasks</h3> <ul> <li>Replay the four compatible commits on 3.0.x.</li> <li>Release 3.0.5 from 3.0.x and 3.1.0-alpha1 from 3.x.</li> <li>Unpublish 3.0.4.</li> <li>Warn in the 3.0.5 release notes that anyone who enabled Domain Config Switcher from 3.0.4 is necessarily on domain 3.1 and must move to 3.1.0-alpha1, not 3.0.5: that submodule is absent from 3.0.5, and updating with it still enabled breaks the site.</li> </ul>
