Permission issues with PHP 7.4

[ArnCo]

Hi Grav team,

I just upgraded to PHP 7.4.0, and now have permission issues on my logs and doctrine directories.
Here's the stacktrace:

  | UnexpectedValueException: The stream or file "/usr/share/nginx/html/[redacted]/logs/grav.log" could not be opened: failed to open stream: Read-only file system in /usr/share/nginx/html/[redacted]/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php:108

  | #6 [internal function]: Whoops\Run->handleException(Object(InvalidArgumentException))
  | #7 {main}

I use:

• PHP 7.4.0 (cli) (built: Nov 30 2019 10:43:49) ( NTS )
• PHP-FPM 7.4.0
• Zend Engine v3.4.0, Copyright (c) Zend Technologies
• Grav 1.6.19

The permissions are properly set on directories (775 +s) using the documentation's script, and rolling back to 7.3.8 fixed the problem.

Is there any fix that I missed ?

Kind regards,

ArnCo

This tells it all: failed to open stream: Read-only file system

So likely your server does not allow you to write to /usr folder, you will likely need to move the site to some other location, like /home/user/www to make it to work.

Hi @mahagr , thanks for your comment, it lead me to the cause of the issue.
Systemd unit for php-fpm 7.4 is hardened with sandboxing, more particularly, ProtectSystem is set to true, which forbids it to write to /usr, /boot and /etc.

I'm closing the issue.

Cheers,
