Can't upload files after module enabled

I'm seeing similar behavior using version 2.0.1 with Drupal 10. This is happening both on an instance hosted on Pantheon as well as in a development stack running on Lando. Uploads fail regardless of scan mechanism (I've tested Executable and both Daemon mode options. The site logs error messages like: Error: Call to undefined method Drupal\Core\Extension\ModuleHandler::getImplementations() in Drupal\clamav\Scanner->isScannable() (line 120 of /app/web/modules/contrib/clamav/src/Scanner.php).

Any new findings? Or a way to get this working/workaround?

I've had this happen with 2.0.2-rc1. Did you change anything else that made it work?

@KlemenDEV The issue I experienced was due to a change in the Drupal 10 ModuleHandler API.

That was fixed in issue 3324573 🐛 D10: Call to undefined method Drupal\Core\Extension\ModuleHandler::getImplementations() Fixed , which was then included in ClamAV release 2.0.2 →

I would expect upgrading to 2.0.2 to resolve this for you (unless your root cause is due to some other issue).

Ok tested with 2.0.2, same problem. Nothing is logged in the logs, the status page detects ClamAV correctly, though.

Code still seems to hang at $response = trim(fgets($scanner_handler));

Can you perhaps try using clamdscan as an example client to verify that it's possible to interact with your clamd instance successfully from the same place that PHP is running?

Hi, thanks for the suggestion. I will verify this asap

I think this is indeed a file permissions issue as the daemon can't access the files.

It may be good to log some error when this happens

Turns out it was apparmor issue on Ubuntu. Adding Drupal files folder to AppArmor read permission for clamav fixed this.

I will leave issue open if someone wants to add some logging (if this is technically doable) to this module to not just silently fail in those cases

Happy to get more logging if its possible and useful, until then, closing as to not leave issues open forever without active work.
