Does this site look broken?. Use the LitterTray web for test cases.

Every run of a view script calls TWiki::Access::checkAccessPermission (at least) twice, with nothing much happening in between:

  1. TWiki::Store::readTopicRaw directly calls checkAccessPermission
  2. after return from the Store, TWiki::UI::View::view calls TWiki::UI::checkAccess, passing the topic text. This routine, however, ignores the topic text and calls checkAccessPermission again.

This has to be investigated further. But since checkAccessPermission needs preferences from both the topic in question and the WebPreferences, double work should be avoided even if it is cached.
