If you use:

# /etc/nginx/include.d/log_debug.conf
access_log /var/log/nginx/${host}-access.log;
error_log /var/log/nginx/${host}-error.log debug;

Your access log will interpolate ${host}; while not interpolating it on the error log.

You end up with a file called: ${host}-error.log



How reproducible

Set up some configuration and add this line inside server {} for the error log to use the host variable:

access_log /var/log/nginx/${host}-access.log;
error_log /var/log/nginx/${host}-error.log debug;

Try making it err (generate errors).

Actual results

You will end with a proper access file; called, for example: example.tld-access.log and the ${host}-error.log file.

Expected results

You should see example.tld-access.log and example.tld-error.log

Additional info

This bug has been reported on the Fedora Bugzilla already but they decided it was not a bug. Perhaps this is an enhancement request?

The error_log directive doesn't support variables, and it's highly unlikely it will - as error log is something needed to log errors, and errors may happen, in particular, while interpolating variables.
