hook_boot only invoked on "normal cached" page views, not on uncached page views

Chris: hook_boot should run like hook_init in D5. This means hook_boot will not fire in aggressive caching mode.

@chx: now, boot fires, but the function_exists('drupal_get_path_alias') gives "false"... and path lookup doesn't work in this level. If this will be the final patch i need to duplicate much Drupal Core function in the module. This maybe faster - but not very cool from the api side. Isn't there a better way? e.g. fire at DRUPAL_BOOTSTRAP_FULL, when every function is accessible?

Additional if someone needs the language in this boot stage he cannot access this... it fires later, too

Another maybe (?) bad idea with the current patch could be a require_once in global redirect...

function globalredirect_boot() {

  require_once './includes/path.inc';
  require_once './includes/common.inc';
  if (isset($_REQUEST['q']) && function_exists('drupal_get_path_alias') && !isset($_REQUEST['destination'])) {
    ...
  }
}

major correction... i need to rebuild the complete DRUPAL_BOOTSTRAP_PATH in global_redirect module.

function globalredirect_boot() {
  // DRUPAL_BOOTSTRAP_PATH hasn't fired yet, but we need to do the same
  require_once './includes/path.inc';
  // Initialize $_GET['q'] prior to loading modules and invoking hook_init().
  drupal_init_path();
  require_once './includes/common.inc';

  if (isset($_REQUEST['q']) && function_exists('drupal_get_path_alias') && !isset($_REQUEST['destination'])) {

Well, i think you are talking about my case http://drupal.org/node/161136.

I thought about moving to hook_init, but this hook doesn't fire on cached pages - isn't it? But global redirect need to run earlier and every time, while we must redirect for e.g. from "node/1" to the appropriate url alias - if one exists. This redirect need to be invoked for cached and non cached pages and this requires hook_boot as i understand :-(((.

Aside it would be a great deal if this small piece of code (global redirect) will be integrated into core to get rid of duplicate content without any extra modules... so we don't need to care of all the above problem at all.

I'm reopening this for a D5 backport, while chx found this bug exists in D5, too.

D5 patch attached

Well, i think it changes some important things and will break some modules like global_redirect. I'm not sure if the patch is correct, so please review carefully. And we don't have a hook_boot... maybe it's better to stay as is... i change this only after chx said this problem is inside D5, too. not sure if this is fixed by the patch correctly, while i'm not so deep inside bootstrap part.
