Summary0001926: Add Xdebug mode's source to xdebug_info() output

After migrating from xdebug 2.x to 3.0 I am not able to use the profiler anymore. Step debugging works fine.

Content of my xdebug.ini:


The output dir is writable for www-data.

This output of \xdebug_info() confuses me:

Feature Enabled/Disabled Docs
Development Aids disabled
Coverage disabled
GC Stats disabled
Profiler disabled
Step Debugger enabled
Tracing disabled

Directive Local Value Master Value Docs
xdebug.mode profile profile
xdebug.start_with_request trigger trigger

So xdebug.mode is profile but the matrix with enabled/disabled features still says that the step debugger is enabled (and YES, it is, it still connects to my IDE), but the profiler not. From my understanding those values should correlate, or did I miss something?

  • Do you perhaps have an XDEBUG_MODE environment variable exposed? You can check that with 'var_dump($_ENV);'

The information in xdebug_info()'s matrix is what Xdebug really sees, and beyond setting the xdebug.mode INI setting, the only way how this can be overridden is by the XDEBUG_MODE env variable. Sometimes IDEs do make that change in their run configurations.

Thanks a lot, indeed there was a configuration I didn't know about in my docker environment which has defined XDEBUG_MODE. Now the profiler works as expected, thank you! :-)

Is there a possibility to give a hint in the xdebug_info() - maybe similar to "local value" and "master value" - to see that xdebug.mode has been overriden by this environment variable?

By the way: I really like XDebug 3 with the new info page and the improved logging, great work!

I've added the source of the modes to xdebug_info() now.
