Unfortunately, I've been told that all further communication with
Jimmy should go through our HP person, Jim Blandy.  So any help with
dejagnu is going to have to come from them or be properly scheduled.

In the meantime, I've switched my automated tester to manual mode for
combined-tree integration, and made its heuristics more paranoid.  If
I find dejagnu breaks again, I'll just freeze it at the
last-known-good version.  Hopefully this will limit the damage.

I'd suggest adjusting the documentation.

Geoff,

I don't know that pulling Jimmy's dejagnu patch was the best thing to
do.  In a way it is like me pulling a G++ patch just because it has (yet
again :-) broken the GDB/C++ testsuites.  If I did that I'd be
(understandably) hounded out of town by the GCC team :-(.  Instead, what
one would hope would happen is \x12 that the groups try to co-operate and
resolve problems as soon as they are found.  If the GDB team find
problems they push patches back to GCC.

For DEJAGNU, checking that a change regresses none of GDB, GCC or
BINUTILS would be a good thing (tm).  However, as things currently
stand, this not straight forward.  Instead we are reliant on people,
such as yourself, identifying problems and reporting them so that they
can be fixed (and not reverted :-).

	enjoy,
		Andrew

Jimmy,

As an asside, you (and others) may be interested in the attatched
files.  It lets you use CVSup to create a merged tree.  It may be
possible to build / test it - no promises though!

If I may, let's retire this thread ... there're assumptions and
perceptions I made, both in the dejagnu design and in the working
process, that caused the dejagnu regression and the following
communications that's less than desirable ... and my apologies to the
GCC project which wasted time tracking my changes down :)

Changes to odd components like dejagnu with little documentation nor
visibility (until it breaks) are dangerous.  Fortunately I don't have
further changes in this area ... as to the couple of patches, I'm sure
we can work it through without further disturbance.  It's never too much
to be reminded that working on a OpenSource project requires extra
prudence and patience ... which is something the HP WDB team is prepared
to accept.
