Sync the files in Kernel/Config/Files/User when S3 syncing is active

[bschmalhofer]

There is still another set of config cache files in Kernel/Config/Files/User. Presumably these files have to be treated like the ZZZ*.pm files. See the implementation in Kernel/System/SysConfig/Base/UserSetting.pm .

Applied a couple of fixes, regarding:

• creating the directory Kernel/Config/Files/User
• removing obsolete user config files not only in the file system, but also in S3

Tests look better now,

Unittest look better now. Let's do a manual sanity check. Using the SysConfig setting Ticket::Frontend::PlainView as an example as per Kernel/Config/Files/XML/Ticket.xml is has UserModificationPossible=1 but UserModificationActive not set. The set up is Docker with two web containers, one daemon container, and /opt/otobo is not shared.

• Create agent tina with rw in the group users
• Check: directory User exists in neither of the two web container, nor in MinIO
• Login as tina
• No "Advanced" section in AgentPreferences
• Log in as root@localhost
• Allow user modification for Ticket::Frontend::PlainView

Looks like allowing user modification of sysconfig settings is not really working. For a started, the Subaction UserModified seems to be not implemented in Kernel/Modules/AdminSystemConfiguration.pm .

Syncing User files seems to work. Support in the WebApp is questionable, see #1788. Closing this issue.

The code for removing no longer needed User config files looks broken too. The subdirectory 'User/' must be included when checking in S3.

             # user specific overrides of the SysConfig
             # note that POSIX does not allow to match multiple digits, so we need an extra filter
-            push @ObsoleteFiles, grep
-                { !$SubPath2Properties{ basename($_) } }
-                grep
-                { m!/\d+\.pm^! }
+            push @ObsoleteFiles,
+                grep { !$SubPath2Properties{ 'User/' . basename($_) } }
+                grep { m!/\d+\.pm^! }
                 glob "$Self->{Home}/Kernel/Config/Files/User/[0-9]*.pm";
