Configurating Transactional File Locking and Memcache After 10.3.1 Upgrade

Steps to reproduce

  1. Install Owncloud 10.3.0 release
  2. Login to Web Interface
  3. Access Settings Page
  4. Review Security & Warnings at Top of Page
  5. See attached screenshot

Expected behaviour

Warnings should disappear after server-side configuration setup

Actual behaviour

The warnings do not disappear. Gives the appearance that something is not configured properly.

Server configuration

Operating system:

CENTOS 6.10 [dedicated17] * [ v84.0.9]

Web server:

Linux

Database:

MySQL

PHP version:
7.1

ownCloud version: (see ownCloud admin page)
10.3.1

Updated from an older ownCloud or fresh install:
Fresh install

Where did you install ownCloud from:
Softaculous App Installer

Signing status (ownCloud 9.0 and above):

Login as admin user into your ownCloud and access 
http://example.com/index.php/settings/integrity/failed 
paste the results into https://gist.github.com/ and puth the link here.

Nothing to paste here.

The content of config/config.php:

Here is the link to file https://www.dropbox.com/s/zlfrqsumqnu40de/config_report_20191118.json?dl=0

Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.

or 

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder

*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

List of activated apps:

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.

Are you using external storage, if yes which one: local/smb/sftp/…

No

Are you using encryption: yes/no

No

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/…

WebDAV

LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';


Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Operating system:

Logs

Hello,

could you also post your config.php, anonymize first what’s irrelevant (passwords, etc …)
You should have:

  'filelocking.enabled' => true,

Don’t forget to restart PHP if you have some opcache around.
Do you have redis or memcached installed too ?
It seems it’s activated but that you simply use the database for the locking.
Please have a look at this doc too.
Cheers.

Would you prefer to hide the warnings and have a overall slower system than the one you could have by installing some additional things?

ownCloud can’t (or shouldn’t) install everything by itself, but the bare minimum to work properly.

(sorry to quote, but I’m just making an example) would you prefer ownCloud to install redis in the same server magically? Well, there are people who don’t and have the redis server in a different host, and it would annoying for them to have to uninstall something that wasn’t requested in the first place.

Those warnings are there for the admin to decide what to do. Most of them are recommendations for a better overall experience, but it requires additional setup that could be more complex to do for some admins and can be done by ownCloud.
