# Xdebug: off by default on CLI (drush, composer) — mode=debug alone still hooks every
# function call and is what makes CLI commands slow, even with start_with_request=trigger.
# Use `XDEBUG_MODE=debug XDEBUG_TRIGGER=1 drush ...` (see xdebugon/xdebugoff aliases) to debug a CLI run.
# FPM loads an extra ini dir that restores mode=debug + start_with_request=yes for web requests.
# FPM loads an extra ini dir: web debugging stays available (browser XDEBUG_SESSION trigger),
# but never tries to connect on its own — start_with_request=yes cost a ~15s connect timeout
# on every request served by a cold worker when no IDE listens on 9001.
