Docker4drupal: 404 for one file, but not for others

[ChristianNally]

phpinfo.php is giving me a 404 result, where another file is accessed without a problem.

ls -l test.html phpinfo.php
-rw-r--r-- 1 christiannally wheel 18 27 Feb 14:39 phpinfo.php
-rw-r--r-- 1 christiannally wheel 26 27 Feb 14:40 test.html

I can edit test.html and the changes work right away. Accessing phpinfo.php returns a 404.

For security reasons the drupal-nginx image returns 404, for all not whitelisted PHP files. You can see it in the template https://github.com/wodby/drupal-nginx/blob/master/templates/d7-vhost.conf.tpl#L228-L230.

If you like to see the phpinfo, you can always log in into your Drupal installation as an admin and open admin/reports/status/php

[ChristianNally]

Thanks @szeidler

While I have you on the line, I've not yet been able to get my own Drupal code working. I could see php info via 'php -i' in that container, but setting the error log location etc. in settings.php hasn't enabled me to get full 500 error text.

I am getting some log entries that show the occurance of the 500 error, but not the actual error message itself.

I may be having trouble because I'm not used to nginx administration. Do you have a "tip jar" I can contribute too?

Thanks for the work on this excellent project!

When you set $conf['error_level'] = 2; in your settings.php, Drupal should present you errors and exceptions on the screen.
As I'm "only" a Docker4Drupal user and no maintainer I cannot explain why they are not streamed to the logs :)

[csandanov]

I cannot explain why they are not streamed to the logs :)

Don't you see errors in stdout after changing the error_level?

[robertoperuzzo]

I added $conf['error_level'] = 2; in my settings.php, but I don't see any php errors in stdout yet (running docker-compose logs php).

[csandanov]

AFAIK, Drupal (at least Drupal 7) uses its own error handlers and have two error log destinations: dblog and syslog. There's no syslog daemon in php container because, you know, containers, we have one process per container. You can check it by commenting the following lines in _drupal_bootstrap_configuration():

  set_error_handler('_drupal_error_handler');
  set_exception_handler('_drupal_exception_handler');

Solutions:

1. implement your own _watchdog hook and stream errors to the default error_log (which is container's output)
2. Use monolog module with udp syslog plugin and stream all errors to rsyslog container as described at https://wodby.com/stacks/drupal/docs/containers/rsyslog/, this way you'll see all errors in rsyslog container output

[csandanov]

Ok, turns out we had a problem here after all, log_errors was disabled. It's obviously a misconfiguration. Although the written above is still correct, drupal uses its own handler

[csandanov]

Fixed in 5.0.4
