I spent about two hours last night debugging a call into mnesia. I
finally found my error but it took a very long time to step..step..step
through many lines before I found exactly what triggered the mnesia:abort().
The call into mnesia was:
The problem of course is the return result was simply:
No stack trace...just a return from the shell process.
By putting a breakpoint in mnesia_schema and stepping through for a very
long time, I was finally able to catch the code which called
mnesia:abort(). (There are many places in mnesia_schema where the
mnesia:abort() is called).
I feel like there must have been a better way to close in on the error
than what I did. For example, is there a way to get a report when
another process "throws" an error. What if I have no idea, as in this
case, how the error was generated..the "error" tuple was simply passed
back to the Client process. Any suggestions?
thanks, ke han
