[wingide-users] Problems with wingdbstub.SuspendDebug

Wing IDE Support support at
Thu, 3 Apr 2003 15:19:00 -0500 (EST)


The API will only work if you're launching the debug process from outside
of Wing.  If you debug from within Wing, the debugger is already going by
the time you reach the import of wingdbstub, so the module does nothing
and doesn't set up the debugger API.  When you ran from the command shell
it also didn't work because there's a bug in SuspendDebug that needs 
fixing (oops, thanks for pointing it out!).

However, you probably don't need to use the API anyway.  At this point
this is really only there for very unusual debugging scenarios.

Try removing your calls to the API and placing the import of wingdbstub
where you currently have the ResumeDebug call.  This will delay starting
debug until that line is reached.

If you want to launch the process from the IDE, use the Execute items
in the Run menu instead.  This runs things outside of the debugger and
lets wingdbstub do its work when it is imported.

If you do need .wingdebugpw, it's in ~/.wingide on Linux/Unix, and inside
profiles/[username] in your Wing installation on Win32.  However, if both 
processes run as the same user then the debugger looks up the file 

Hope that helps... if not, please let us know.
