Hi Ralf:

Pushed this branch to mercurial on sourceforge:

  https://sourceforge.net/p/roundup/code/ci/
reactor_pass_changed_oldvalues/tree/

can you take a look and see if it looks sane?

It has the possibly undesired side effect of removing quiet
parameters from oldvalues.

The commit message has details on how we can restructure so that
the quiet params are filtered on return from set(), but
made available to the reactors.

With the old way, you could see the prior values for quiet changes
if you wanted to do something with them, but you had to do your own
comparison to see if the parameter had changed.

In theory you can look at the journal for the quiet changes by passing
a flag to prevent filtering of the quiet changes provided the parameter
has journaling enabled.
