Drupal 7 not refreshing menus
Here's the code in system_modules_submit() - the function called when admin/modules is saved - that skips over flushing caches if no modules are enabled or disabled:
<?php
// Gets module list after install process, flushes caches and displays a
// message if there are changes.
$post_install_list = module_list(TRUE);
if ($pre_install_list != $post_install_list) {
drupal_flush_all_caches();
drupal_set_message(t('The configuration options have been saved.'));
}
?>
So, drupal_flush_all_caches() is called only if something has changed, if a module has been enabled or disabled. (That function is what calls menu_rebuild() which is what rebuilds the menus.)
