Also, add more misc details to the 'react' breadcrumb trail. Also,
save get(react) results into dbg2 whenever we write a private projection,
very valuable for debugging.
Also: cleanup PULSE code, add regression commands as option and
controls with some new environment variables. These regression
sequences were responsbile for several fruitful debugging sessions,
so we keep them for posterity and for their ability (with new seeds
and PULSE) to find new interleavings.
So, the PULSE test is failing, which is good. However, I believe
that the failures are all due to the model now being *too strict*.
The model is now catching failures which are now benign, I think.
{bummer_NOT_DISJOINT,{[a,b,b,c,d],
[{a,not_in_this_epoch},
{b,not_in_this_epoch},
{c,"[{epoch,1546},{author,c},{upi,[c]},{repair,[b]},{down,[a,d]},{d,[{ps,[{a,c},{c,a},{a,d},{b,d},{c,d}]},{nodes_up,[b,c]}]},{d2,[]}]"},
{d,"[{epoch,1546},{author,d},{upi,[d]},{repair,[a,b]},{down,[c]},{d,[{ps,[{c,b},{d,c}]},{nodes_up,[a,b,d]}]},{d2,[]}]"}]}}},
In this and all other examples, the UPIs are disjoint but the
repairs are not disjoint. I believe the model ought to be
ignoring the repair list.
{bummer_NOT_DISJOINT,{[a,a,b],
[{a,"[{epoch,1174},{author,a},{upi,[a]},{repair,[]},{down,[b]},{d,[{ps,[{a,b},{b,a}]},{nodes_up,[a]}]},{d2,[]}]"},
{b,"[{epoch,1174},{author,b},{upi,[b]},{repair,[a]},{down,[]},{d,[{ps,[]},{nodes_up,[a,b]}]},{d2,[]}]"}]}}},
or
