@luke- will try to reproduce/understand

Thanks @gevorgmansuryan ! Don't hesitate if I can help.

[marc-farre]

@gevorgmansuryan It works with these changes (the bug is gone)!

I tested 3 cache types:

• No caching: no bug
• File: the bug occurs
• APCu: no bug (but cannot be used when more than 1 Humhub instance is installed on the same server)

The bug occurs only on this server, for all Humhub instances installed on it.
So it's a problem of cache with this server (but that occurs on other servers too as we have this bug mentionned on #86 and #74).

I've checked all server settings with the doc, and "Administration" -> "Information" -> "Prerequisites". Everything seems ok.
Config: Ubuntu 20.04 / PHP 7.4 / mod_php

I've done the folowing test in command line (Controller extending yii\console\Controller):

        echo Yii::$app->cache->get('test_key');
        Yii::$app->cache->set('test_key', 'test value');

At the second execution, the "test value" is shown. So caching works.

Thanks for your investigation!

@gevorgmansuryan have you got an idea how to fix this problem without having to add code in the core ModuleAutoLoader class or to enable debug? Thanks!

If it can help, we can have a video call with screen sharing.

@gevorgmansuryan Any idea?

[gevorgmansuryan]

@funkycram thank you. Can you please try to reproduce, and see what jobs are executing. It will help me to find job that using cache incorrectly (uses yii\WEB\UrlRule from cli). 99% it is related to UrlRules caching.

[marc-farre]

@gevorgmansuryan the bug doesn't occurs with jobs, but when executing a command line with SSH, e.g. php yii queue/run -v, but it occurs with any command, except php yii cache/flush-all

I can reproduce only on Humhub instances on production (where many people are using the platform during my tests). If I clone the humhub to have a dev instance, I cannot reproduce the bug, and the only difference I can see is that nobody is using the dev instance.

I have 2 ways to solve the bug:

• waiting for the next cron job (the queue/run every minute)
• flushing the cache by executing the php yii cache/flush-all command

In the settings, "Cache Backend" is set to "File".

[gevorgmansuryan]

@funkycram yeah, i know that it's doesn't occurs with jobs. There is some job or command that calls/uses Web/UrlManager and stores incorrect cache of Rules. Since i can not reproduce it anyway, there is no other chance to reproduce it and find the problem.
We can try to:

• move urlManager config keys from common.php to web.php and try to run commands/queue and see what will happen. Most probably we'll see the error in file which uses UrlManager
• try the same with enabled debug mode

[marc-farre]

@gevorgmansuryan thanks for you suggestions.
In the 'components` section, I moved

        'urlManager' => [
            'showScriptName' => false,
            'enablePrettyUrl' => true,
        ],

from common.php to web.php.

The problem is still there.

Then, in /index.php, I uncommented defined('YII_DEBUG') or define('YII_DEBUG', true); (only this line, not the YII_ENV one).
This solves the problem.

I tried commenting it and uncommenting it again, and this is really what makes the difference systematically.

[gevorgmansuryan]

@funkycram interesting :) Can you please comment back YII_DEBUG line, change line 47 from protected/humhub/components/bootstrap/ModuleAutoLoader.php to if (true || $modules === false || YII_DEBUG) { and try again?
