Weird behaviour for logged in users in maintenance mode

[jvillafanez]

Steps to reproduce

1. Log in with an user
2. From the OC command line, set the maintenance mode (sudo -u www-data ./occ maintenance:mode --on)
3. Do some ajax stuff with the logged in user (for example, in the files view, try to get the contents of a folder)

Expected behaviour

You are kicked to the maintenance screen

Actual behaviour

You stay in the page getting errors. For example, if you try to get the contents of the folder, you stay in the current folder instead of changing it; if you want to know the file shared with you, you'll see that there are no files shared with you even though it's wrong.

This behaviour stays until the user loads another page, then the user is redirected to the maintenance screen

Server configuration

Operating system: ubuntu 14.04

Web server: apache 2.4.7

Database: mysql

PHP version: 5.5.4

ownCloud version: 8.0.3RC1

Updated from an older ownCloud or fresh install: fresh install

Browser: firefox

pretty much the same problem like when LDAP and others are not there.
We need a wrapper in the get(), post(), ... methods in js to catch these cases and redirect.

cc @MorrisJobke can you find the ldap exception issue for a cross link quickly?

@nickvergessen #15332 or #15357 ?

The later one is what I was looking for

This one is tricky. Every app needs to fix their ajax calls to be able to react properly on 503 http codes and automatically show a proper error message or redirect accordingly.

Checked also with single-user mode: same behaviour with normal users

[PVince81]

in recent versions, a notification will appear that an error occurred and the page will reload, which will redirect to the login page (or maintenance page followed up by login page when it comes back)
