Hurray! I'm so happy now -- the memory leak is gone and the update of
variables works elegantly in scotty now. A million thanks to the people
who have come with excellent tips!
My problem was the following: scotty got bigger and bigger using only
instances and not updating the global variable. There was a problem with
binding the global variable to the scotty internals.
The solution was: Removing the "-agent $interp" where $interp contains the
safe tcl/scotty commands allowed to be executed. I replaced this with
"-agent {}" and things worked right away. Thanks to Buz's little example!
Hm... Guess I really should have used "safe tcl/scotty" commands as done
in the scotty agent example (distribution). Is it bad to skip this
safety stuff? If so, what's the deal with the aliasing? I have a proc
that updates the mib (setMIB), should I add a "setMIB alias" ? or should
I add every Tcl command in the alias list?
However, it works now!!! Lovely!!! I'm happy :)
Thanks again, folks!
