RSS feed cache not getting reset on new content

function boost_cache_expire($path, $wildcard = FALSE) {
  // Sanity check
  if (boost_file_path($path, FALSE) === FALSE) {
    return FALSE;

  // Get list of related files
  $tempA = glob(boost_file_path($path, FALSE, NULL) . (($wildcard) ? '*' : '') . BOOST_FILE_EXTENSION, GLOB_NOSORT);
  $tempB = glob(boost_file_path($path, FALSE, NULL) . (($wildcard) ? '*' : '') . BOOST_XML_EXTENSION, GLOB_NOSORT);
  if (!empty($tempA) && !empty($tempB)) {
    $filenames = array_filter(array_merge($tempA, $tempB));
  }
  elseif (!empty($tempA)) {
    $filenames = $tempA;

    $filenames = $tempB;

  // Flush expired files
  foreach ($filenames as $filename) {
    boost_cache_kill($filename);
  }
  return TRUE;
}

Looks like I need to replace glob with a database operation.

In short the front page rss feed is called feed_.xml in the boost cache; the html is called _.html. Doing a file search for the front page doesn't work too well in this case.

boost_cache_expire_derivative() will have to be redone; boost_cache_expire() might be killed. boost_cache_expire_derivative() will directly call boost_cache_kill().

When boost_cache_expire_derivative() is called will find aliases & redirects so it can find a matching filename in the database. Once a match is found, it then gets the page_callback, page_arguments and page_id; searching the database that match all 3. These are the files in the cache that need to be expired. Should cover html, xml, and ajax & url variables.

This patch is for the latest dev. It can't be done very easily without the latest changes that have gone in.

No, I'll have to write in a special front page handler. What's the URL of your front page feed?

it's /rss.xml correct?
Only holds content promoted to the front page right?

fixed some bugs in here as well.

more bug fixing...
