Updating dependencies with a function
I used to add module_enable(array('whatever')) in an update hook every time I’d want add a dependency. The problem is every call to module_enable() is very, very long.
Now, I add this function to my site deployment module and call it from an update hook. Every time something changes, I just change the number in my hook name.
/**
* Update dependencies and disable unwanted modules.
*
* Prepend with an underscore (_) to avoid confusion with hook_update_dependencies().
*
* See http://blog.dcycle.com/blog/70/updating-dependencies-function
*/
function _mysite_deploy_update_dependencies() {
$info_file = drupal_parse_info_file(drupal_get_path('module', 'mysite_deploy') . '/mysite_deploy.info');
if (isset($info_file['dependencies'])) {
module_enable($info_file['dependencies']);
}
if (isset($info_file['to_disable'])) {
module_disable($info_file['to_disable']);
drupal_uninstall_modules($info_file['to_disable']);
}
}
My site deployment module’s install file might contain something like:
mysite_deploy_update_7123() {
_mysite_deploy_update_dependencies();
features_revert();
}
When I change something in a feature, or add/remove dependencies, I just change 7123 to 7124, like this:
mysite_deploy_update_7124() {
_mysite_deploy_update_dependencies();
features_revert();
}
Now, all environments can just use drush updb -y to update features and dependencies.
