Summary0002259: Does not stop on breakpoints when files are located on a UNC path drive
Description

When the files to be debugged are located on an UNC drive like \NAS\xyz, instead of a local drive, the breakpoints are never hit and they are marked as unverified. Also using a network attached drive does not help, because the IIS file location configuration is set to the UNC drive.

Steps To Reproduce

Add a php project to VS Code and make a php file containing just the xdebug_info() function. Install PHP, Xdebug and IIS locally and the php file on a UNC drive like an NAS (\NAS\xyz). Add a Web site on IIS and let the virtual directory point to the UNC path to the NAS (\NAS\xyz). The set a breakpoint on the xdebug_info() an start xdebug. The breakpoint will be marked as unverified and will never be hit. If you do absoltely the same on a local drive like D:\xyz, everything works as expected.

Now here is the debug.log and the xdebug info.

If you need any more information, please let me know.

Many thanks and best regards.

Hi,

Sorry for the uberslow reply.

Looking at the log, I see that your script file is seen as //MAINSERVER/SHARED/xdebug-info.php, but your IDE sets it as //mainserver/shared/xdebug-info.php (ie, lower cased). Xdebug does case-sensitive matching on these, I believe.

Can you try to:

  1. figure out if you can get your IDE to use uppercase letters for MAINSERVER and SHARED?
  2. create a similar log like you have, but then also with xdebug.log_level=11?

I wonder whether I need to relax this check to case-insensitive for the first two elements, if an UNC path is detected on Windows (you're on Windows, right)?

cheers,
Derick

Alternatively, you can perhaps also make a path mapping to work around this — either from //MAINSERVER/SHARED to //mainserver/shared (or the other way around, I can never remember).

I can't reproduce this, and there is also no feedback on suggested workarounds. So I am closing this ticket. Feel free to open a new one if you can provide additional information.
