In 16.11.00 with memcached enabled, staging MARC records fails with "Upload status: Denied". It works after disabling memcached.
I'm not seeing this. We need more details.
I just had it again, on an instance where memcached was turned off. Will post more if I find a pattern.
I think this time it was turning off memcached but not restarting apache. Which is not really a Koha bug but user error ;) I'll leave the bug open and see if I get it again.
Lowering the severity as it's not confirmed.
Tested on master: With Plack and memcached, start an upload with tools/upload. Fine! Stop the memcache service. With Plack only, start a second upload. Also fine! The Denied status normally is triggered by a wrong authentification. A possible scenario could be using memcached for the session data. If you are logged in, so have a session, and after that you enable or disable memcache, the session cannot be found any longer. So should trigger an authentification error; this is more or less what we expect. Since the upload button starts an ajax call to upload-file and upload-file does only use check_cookie_auth and not get_template_and_user, you will just see a Failed status here. Clicking on another menu link should redirect you to the login page. Mirko: Can you check if you used memcache for session data?
No more reports of this since 16.11, looks like a user error.
