Code

function path_alias_xt_init() {

  // Purists look away...
  // There is no suitable hook to override core's drupal_get_path_alias()
  // behaviour. So we either take on the impossible task of rewriting all
  // modules that call it, or we redefine its body to make a simple call back to
  // this module. We can do this programmatically by taking advantage of the
  // PECL runkit extension. The runkit needs to be compiled and placed in the
  // /extensions (or /ext) directory pointed to by the extension_dir directive
  // in php.ini.
  // Dynamically load the runkit. This may not be supported on multi-threaded
  // web servers.
  // If the statement below produces an error on your system, comment it out and
  // make sure that you have "extension=runkit.so" in your php.ini.
  // Alternatively, apply the simple edit to includes/path.inc as described in
  // the README file.
  // Dl('runkit.so');.
