Summary0002070: xdebug.start_with_request=trigger not working, starts all the time


XDEBUG seems to be ignoring xdebug.start_with_request=trigger and treat it the same as xdebug.start_with_request=yes.

My debugging sessions start all the time, even when I don't set any trigger.

Here's my config:


But when i do anything at all, XDEBUG tries to start a debug session, for example:

rasmus@e72a5b142652:/var/www/symfony$ php -r "echo 'Hello'.PHP_EOL;"
Xdebug: [Step Debug] Time-out connecting to debugging client, waited: 200 ms. Tried: (through xdebug.client_host/xdebug.client_port) :-(
TagsNo tags attached.
Operating SystemWSL
PHP Version7.4.20-7.4.29

Can you add -dxdebug.log=/tmp/xdebug.log and -dxdebug.log_level=10, and then attach what shows in the /tmp/xdebug.log file?

Here you go:

rasmus@e42e6073ad65:/var/www/symfony$ php -dxdebug.log=/tmp/xdebug.log -dxdebug.log_level=10 -r "echo 'Hello'.PHP_EOL;"
rasmus@e42e6073ad65:/var/www/symfony$ tail /tmp/xdebug.log

rasmus@e42e6073ad65:/var/www/symfony$ echo $XDEBUG_CONFIG

For good measure I added the content of the XDEBUG_CONFIG variable.

this is by design, as you can see in this test.

If the XDEBUG_CONFIG environment variable is set, then this also acts like a trigger. This is due to legacy reasons, which I did not want to break with Xdebug 3.

In order to avoid this, you must not set XDEBUG_CONFIG, and instead move the configurations that you have made in there to your xdebug.ini (or php.ini) file.

I will eventually remove this XDEBUG_CONFIG trigger in a future version of Xdebug.

Ok thansk.

Could at least the documentation be updated? I spent a way too big amount of time on this because I trusted the documentation.

There's already a note about "legacy" here: why not add the fact that simply setting XDEBUG_CONFIG to any value at all act as a trigger?

On a personal note I feel like going from Xdebug 2 to 3, you'd expect breaking changes and it's fine to break this one.

I've documented this now, and also created a ticket to track the removal of these legacy triggers (there is another one, from 0002068):
