This adds a file lock to the config in hope that this prevents race conditions as reported in https://github.com/owncloud/core/issues/11070
Testplan:
- [ ] Delete config.php and make it read-only => Error is thrown that it is not writeable
- [ ] Installation still works
- [ ] Changing config settings works (i.e. using the SMTP config switches in the administration menu)
- [ ] Your PC didn't blow up
- [ ] Installing the news app and the "Disable AppCode checker" app did not destroy your installation
Only skip the main config
Otherwise read only additional configs might not be processed
Test on tmpdir
We do not want to follow redirects to other protocols since they might allow an adversary to bypass network restrictions. (i.e. a redirect to ftp:// might be used to access files of a FTP server which might be in a secure zone and not be reachable from the net but from the ownCloud server)
Get final redirect manually using get_headers()
Migrate to HTTPHelper class and add unit tests
Assume a permission issue whenever a file could not be deleted.
This is because some storages are not able to return permissions, so a
permission denied situation can only be triggered during direct
deletion.
Fix upgrade process when apps enabled for specific groups
Fix issue where the currently logged user was causing side-effects when
upgrading.
Now setting incognito mode (no user) on update to make sure the whole
apps list is taken into account with getEnabledApps() or isEnabled().
maintain deprecated \OC::$session when getting or setting the session via the server container or UserSession
restore order os OC::$session and OC::$CLI
