Incompatibility with Nextcloud 28.0.2 - Makes Files not showing up in Files Web Interface

Closed this issue 4 months ago · 21 comments

After Nextcloud update to version v28.0.2 the Photo Sphere v1.28.0 extension make files not showing up on Nextcloud Web Interface Files tab (All Files), disabling Photo Shere Nextcloud extension makes Nextcloud function correctly.

Answer 1 · 2024-02-13T19:10:01.000Z

Do you have any further information like browser- and backend-logs?

Answer 2 · 2024-02-13T19:58:36.000Z

I have tried several (Firefox, Chrome, Brave, Edge) web browsers with empty cache and all them presented the same problem. I don't have backend logs now, will check later, behaviour can be replicated enabling/disabling the extension.

I can confim that this problem is reproducable and goes away with disabbling this plugin.
Looks that there is also some conversation of it

Sorry for the inconvenience folks. Hope I will find some time soon to look deeper into this. Will keep you posted.

Answer 7 · 2024-02-26T20:00:36.000Z

Hey guys, I just tried to reproduce the issue on a fresh NC28 docker installation. Unfortunately I wasn't able to - everything worked like expected. Could you please give me some more insights about your setup? Do you have APCU/OPCache installed? Are we talking about a native installation or a docker based one?

Answer 8 · 2024-02-26T20:52:12.000Z

Hi, I have a native installation, and the server is configured to use redis cache, php.ini has zend_extension=opcache enabled. I am using debian based Ubuntu with kernel 5.15.0-97

Answer 9 · 2024-02-27T13:08:50.000Z

I have a native install as well, in an Alpine LXC. Using opcache and redis. Install based on:

Answer 10 · 2024-02-27T17:07:59.000Z

Hello R0Wi, I commented out the return type specification of the two caching functions and everything is working as it should:

Answer 11 · 2024-02-28T22:25:12.000Z

Same here. Native install as well, Ubuntu 22.04.4 LTS PHP 8.1 Redis OPcache in Proxmox 8.1.4 container (kernel 6.5.13-1-pve (2024-02-05T13:50Z).

Answer 12 · 2024-02-29T05:54:23.000Z

Could one of you please share the section of the config.php where the different cache-types are configured? I'm suspecting the Redis cache to cause the issue here.

Answer 13 · 2024-02-29T20:47:58.000Z

config.php:

'memcache.local' => '\\OC\\Memcache\\Redis',
'memcache.distributed' => '\\OC\\Memcache\\Redis',
'filelocking.enabled' => true,
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' => 
array (
'host' => '/run/redis/redis-server.sock',
'port' => 0,
'dbindex' => 0,
'password' => '<pass-obfuscated>',
'timeout' => 0.0,
),

php.ini (only non-default settings shown):

session.save_handler = redis
session.save_path = "unix:///var/run/redis/redis-server.sock?persistent=1&weight=1&database=0&auth=<pass-obfuscated>"

; From nextcloud documentation (https://docs.nextcloud.com/server/21/admin_manual/configuration_server/caching_configuration.html):
;
; (...)
; Adding the following settings in your php.ini file will prevent session
; corruption when using Redis as your session handler:
redis.session.locking_enabled=1
redis.session.lock_retries=-1
redis.session.lock_wait_time=10000

Edit: Just to be sure (didn't expect any change and it didn't): I changed the path in php.ini from /var/run to /run.

Alas, updated to NC 28.0.3, no change, still no files shown with Photo Sphere Viewer enabled.

Answer 15 · 2024-02-29T22:30:22.000Z

From my Nextcloud config.php:

  'memcache.local' => '\\OC\\Memcache\\Redis',
  'memcache.locking' => '\\OC\\Memcache\\Redis',
  'redis' => 
  array (
    'host' => 'localhost',
    'port' => 6379,
    'dbindex' => 0,
    'timeout' => 1.5,

From my debugging it looks like this guy is returning an array data type:

$cachedXmpMeta = $this->cache->get($id);

And since it doesn't match the specified return data type, XmpResultModel, it is erroring out. Maybe the Nextcloud docker image has the PHP error handling a little less strict than the default 8.2 settings? I don't know if there is a good way to type cast it into the XmpResultModel but removing the return definition worked for me.

Answer 16 · 2024-03-01T06:04:41.000Z

It seems that Redis behaves differently compared to APCU in this case. Since I was using APCU all the time, I wasn't able to reproduce the issue. Will try to find a proper solution ASAP

Seems so indeed. Switched to APCu and files are shown normally again when Photo Sphere Viewer is enabled. Problem gone.

'memcache.local' => '\\OC\\Memcache\\APCu',
'memcache.distributed' => '\\OC\\Memcache\\Redis',
'filelocking.enabled' => true,
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' => 
array (
'host' => '/run/redis/redis-server.sock',
'port' => 0,
'dbindex' => 0,
'password' => '<pass-obfuscated>',
'timeout' => 0.0,
),

Answer 18 · 2024-03-09T20:56:15.000Z

Sorry for the delay. Should be fixed in v1.28.1. Feel free to reopen if you're still facing the issue.

Some details: Redis indeed behaves a bit differently compared to APCU. It returns an array instead of a deserialized object which has been cached before. This should now be covered but in my opinion this is also a Nextcloud issue. From my point of view it shouldn't make any difference which particular cache the system is using - The technical NC interface should always behave the same.

Answer 19 · 2024-03-09T21:34:13.000Z

Thank you for the work to solve the problem, I also have the same opinion, Nextcloud interface shouldn't be sensible for the cache system.

Answer 20 · 2024-03-10T10:04:47.000Z

did you open ticket of this to NC? I totally agree that interface should stay as same regardless of backend. It whould be good to open ticket for nc and cross link these. It may help in future if some other module hits to same issue and nc still had not fix it.

Didn't yet find the time, unfortunately. But that's on my TODO list 😉
