Facet termination event handler ordering is not right #23

Closed tonyg closed 7 years ago

tonyg commented 7 years ago

Running example-termination-scripts-1.rkt highlights many of the problems I'm currently thinking about wrt termination ordering. Just now (as of commit 37cee0c) I got the following output:

starting; x=1
starting; x=1; y=2
on E: f; x=1
stopping; x=1; y=2
on-stop: e; x=1; y=2
stopping; x=1
on-stop: h; x=1
on E: a; x=1; y=2
on E: b; x=1; y=2
stop-when E: g; x=1
stop-when E: c; x=1; y=2
stop-when E: d; x=1; y=2
stop-when E: innermost
INNERMOST STOPPING
INNERMOST STARTING
on rising-edge #t
stop-when rising-edge #t

There's a lot to complain about there. Most glaringly, the INNERMOST STOPPING event is firing before the INNERMOST STARTING event!

I need to (1) analyze the output to see all the problems in it, and then (2) fix them.

Tentative fix for these in 76c1a5b3478eed5130099060e4e7c2df8d9d7281 and 6db1e67a7e4f51016b3ab1c59bd7531a7ac44045.

I'm happy with termination now.
