Issue report:
> Hum, well I upgraded the package then visited the web interface to
trigger the update and it failed; the UI would say there was a
possible CSRF attack and after that it'd be stuck in maintenance mode.
Tried a few times (by editing maintenance to false in owncloud.conf)
and same result each time.
That smells partially like an issue caused by our EventSource implementation, due to legacy concerns the CSRF verification happens within the EventSource handling and not when the actual endpoint is called, what happens here then is:
1. User has somehow an invalid CSRF token in session (or none at all)
2. User clicks the update button
3. Invalid CSRF token is sent to update.php - no CSRF check there => Instance gets set in maintenance mode
4. Invalid CSRF token is processed by the EventSource code => Code Execution is stopped and ownCloud is stuck in maintenance mode
I have a work-around for this problem, basically it verifies the CSRF token already in step 3 and cancels execution then. The same error will be shown to the user however he can work around it by refreshing the page – as stated by the error. I think that’s an acceptable behaviour for now: INSERT LINK
To verify this test:
1. Delete your ownCloud cookies
2. Increment the version in version.php
3. Try to upgrade
=> Before the patch: Instance shows an error, is set to upgrade mode and a refresh does not help
=> After the patch: Instance shows an error, a refresh helps though.
This is not really the best fix as a better solution would be to catch such situations when bootstrapping ownCloud, however, I don’t dare to touch base.php for this sake only, you never know what breaks then…
That said: There might be other bugs as well, especially the stacktrace is somewhat confusing but then again it installing ownCloud under /usr/share/owncloud/ and I bet that is part of the whole issue ;-)
As it turned out the AppStore code was completely broken when it came from apps delivered from the appstore, this meant:
1. You could not disable and then re-enable an application that was installed from the AppStore. It simply failed hard.
2. You could not disable apps from the categories but only from the "Activated" page
3. It did not show the activation state from any category page
This code is completely static and thus testing it is impossible. We really have to stop with "let's add yet another feature in already existing static code". Such stuff has to get refactored first.
That said, this code works from what I can say when clicking around in the AppStore page GUI. However, it may easily be that it does not work with updates or whatsever as I have no chance to test that since the AppStore code is not open-source and it is impossible to write unit-tests for that.

Caches divided up into two groups: distributed and local. 'Low latency' is an
alias for local caches, while the standard `create()` call tries to get
distributed caches first, then local caches.
Memcache backend is set in `config.php`, with the keys `memcache.local` and
`memcache.distributed`. If not set, `memcache.distributed` defaults to the value
of `memcache.local`.
