I'm starting to try to debug the fs locking problems. One of the things
I'd love to have is a stack trace in a static string (so I can have a
stack trace both of the code which ran into a lock & panic'd and also the
code which generated the lock).
To that end, I've added snprintf, and hooks in db_trace to support tracing
to a buffer.
Now all I need is a way to get into the debugger to start the stack trace.
Does anyone know how to do this? Basically I need to be able to latch onto
the current stack frame so trace can go look at it, and to set up whatever
else db_trace_cmd will want.
Is there a db expert around?
Take care,
Bill
