问题
I'm running PHP 7.4 in Docker. I am able to step debug just fine, however, unlike in Xdebug v2 if I add a breakpoint or remove a breakpoint while step debugging I am getting a 502 Bad Gateway message from nginx and the step debugging session just dies.
Am I missing a setting for Xdebug v3 in order to set new breakpoints or remove breakpoints while step debugging without killing the session?
php.ini settings
xdebug.mode=debug
xdebug.start_with_request=yes
xdebug.discover_client_host=true
xdebug.max_nesting_level=1500
Environment variable for Xdebug session set in docker:
XDEBUG_SESSION: docker
回答1:
It's Xdebug issue: https://bugs.xdebug.org/view.php?id=1897 (https://bugs.xdebug.org/view.php?id=1899 is a duplicate of that).
Says fixed for next Xdebug v3.0.1 (you can build from sources if you can and need it now).
UPDATE 2020-12-04: Xdebug 3.0.1 has been released.
