Code path is not updated if no module is loaded in the appup

[Paul Guyot]

Hello,

With R13B04 (and earlier), we noticed that the code path is not updated when installing a release if no module is to be added/deleted/reloaded in the .appup file. This is a problem as the release can consist in an update to non-code files, such as MIBs, resources in priv directory, etc.

For example, if the appup is the following:

{"16",
   [{"15",
       [
       ]}
       ],
   [{"15",
       [ 
       ]}
   ]
}.

The generated relup is the following:

{"802",[{"801",[],[point_of_no_return]}],[{"801",[],[point_of_no_return]}]}.

application:which_applications returns that the application version "16" is installed and running. However, code:priv_dir and code:get_path refers to version "15" of the application.

Regards,

Paul
