Summary0002153: xdebug.mode in PHP-FPM pool ignored
Description

The xdebug configuration use only global/default value for xdebug.mode settings and ignore php-fpm pools configuration

Steps To Reproduce
  1. Configure custom pool (e.g. awesome):

; Start a new pool.
; the variable $pool can we used in any directive and will be replaced by the
; pool name:
[xdebug-awesome]

user = www-data
group = www-data

listen = /run/php/php8.1-$pool-fpm.sock

listen.owner = www-data
listen.group = www-data

pm = dynamic
pm.max_children = 80
pm.start_servers = 5
pm.min_spare_servers = 3
pm.max_spare_servers = 35

php_admin_value[xdebug.mode] = debug
php_admin_value[xdebug.start_with_request] = yes
php_admin_value[xdebug.idekey] = key-$pool
php_admin_value[xdebug.client_host] = 127.0.0.1
php_admin_value[xdebug.client_discovery_header] = ""

  1. make sure that no other configuration has been provided for xdebug in PHP config files
  2. Configure simple setup with php-fpm to serve index.php with 'xdebug-awesome' pool
  3. Add phpinof(); in index.php and check settings:
    • xdebug.mode = debug
    • only development helpers feature is enabled

This is expected, and correct behaviour. xdebug.mode can only be set when PHP starts, due to the way it initialises and register its features with the PHP engine.

I have updated the documentation to make this clearer too:
https://xdebug.org/docs/install#mode

An alternative would be to set up two PHP-FPM servers, each with a different port/socket, and their own PHP configuration through separate php.ini files.
