"Failed to open stream: Permission denied" for cache/data

[neoplex]

Anyone else seeing this behavior?

Having trouble with files in the cache directory under /app/data/storage/framework/cache/data being created with root/root, stalling background jobs and causing frequent disconnects in the frontend.

After changing the user/group for cache/data directory recursively to www-data/www-data, things are working for a moment. Then the same thing happens again. I had a quick go around and couldn't find any obvious misalignment in the configuration or running processes.

AFAICT, everything in the container runs as www-data user. Not sure who is creating these. Can you make a note of the timestamps of the bad directories, next time around? We should try to correlate with app logs.

[neoplex]

It appears that the directories owned by root are created either on the hour or at 45 minutes past the hour. And it seems to be related to those stalled App\Jobs\UpdateFolderCounters job.

@neoplex are you able to reproduce this by running the cron task manually? You can do this by Web Terminal -> Cron on the top. thanks

[neoplex]

It's not the cron job. It's this job that's executed by the queue worker.

Although the PHP script that the queue worker is being executed with runs as www-data.

The timestamps match.

[joseph]

are you on the package 1.13.2 ? just to get that out of the way.

[neoplex]

Yep!

@neoplex unfortunately, cannot reproduce. If it's easy to see this, can you please send a mail to support@cloudron.io and we can take a look to debug this further.

[neoplex]

I've fixed this. Will send a patch via existing support email thread.

I am also going to leave this here:

I finally got around to putting together a fix:

https://github.com/pronetivity/cloudron-freescout/commit/27697c310fb373f1a972c7990f5c00dc3052ee54

A detailed analysis is available here:

Disclaimer: the commit also includes a few quality-of-life changes. The actual fix is limited to the caching adjustments.

Cheers,
