normal caching + OpenCalais causes fatal error

After poking around in Localizer, I suspect this is a localizer issue instead.

Ok. So I removed localizer entirely from my site, and I still get the error.

That tells me it's not a localizer problem.

I've got a cold, so forgive me for filing the issue if this is a time waster. I probably shouldn't file issues while medicated!

I found the problem. All implementations of hook_init in the Calais modules call functions that aren't loaded when pages are cached. See #45190: drupal_get_path() call in category_init() fails for cached pages.

I found that content.module's implementation of hook_init wraps code in this condition:

function content_init() {
  // ensure we are not serving a cached page
  if (function_exists('drupal_set_content')) {
    // we don't do this in hook_menu to ensure the files are already included when
    // views_menu is executed
    if (module_exists('views')) {
      include_once('./'. drupal_get_path('module', 'content') .'/content_views.inc');
    }
    if (module_exists('panels')) {
      include_once('./'. drupal_get_path('module', 'content') .'/content_panels.inc');
    }
    // according to http://drupal.org/node/60526, this should not go in hook_menu
    if (module_exists('pathauto')) {
      include_once('./'. drupal_get_path('module', 'content') .'/content_pathauto.inc');
    }
  }
}

Localizer also checks:

function localizer_init() {
  $scriptname = basename($_SERVER['SCRIPT_NAME']);
  if($scriptname!='index.php') return;
  if(function_exists('drupal_get_path')) {
    _localizer_change_language();
    if(localizer_is_front_page() && localizer_exists_localized_content($_GET['q'], localizer_get_language())) {
      $path = localizer_get_localized_path($_GET['q'], localizer_get_language());
      $apath = drupal_lookup_path('source', $path);
      $path = $apath? $apath : $path;
      $_GET['q'] = $path;
    }
  }
}

The following Calais hooks will need attention:

calais_api_init
calais_init
arc_rdf_init

I'd submit a patch, but caching and bootstrapping is over my head.

The problem happens when normal caching is enabled. It's an inevitable result of using the drupal_get_path in hook_init without checking first that the function is available. It happens every time you attempt to load a page while not logged in and normal caching is active.
