26 /* This function is a pimple that we ought to fix. But it won't be easy.
28 * The surf_solve() function does properly return the set of actions that changed.
29 * Instead, each model change a global data, and then the caller of surf_solve must
30 * pick into these sets of action_failed and action_done.
32 * This was not clean but ok as long as we didn't had to restart the processes when the resource comes back up.
33 * We worked by putting sentinel actions on every resources we are interested in,
34 * so that surf informs us if/when the corresponding resource fails.
36 * But this does not work to get Simix informed of when a resource comes back up, and this is where this pimple comes.
37 * We have a set of resources that are currently down and for which simix needs to know when it comes back up.
38 * And the current function is called *at every simulation step* to sweep over that set, searching for a resource
39 * that was turned back up in the meanwhile. This is UGLY and slow.
41 * The proper solution would be to not rely on globals for the action_failed and action_done swags.
42 * They must be passed as parameter by the caller (the handling of these actions in simix may let you
43 * think that these two sets can be merged, but their handling in SimDag induce the contrary unless this
44 * simdag code can check by itself whether the action is done of failed -- seems very doable, but yet more
47 * Once surf_solve() is passed the set of actions that changed, you want to add a new set of resources back up
48 * as parameter to this function. You also want to add a boolean field "restart_watched" to each resource, and
49 * make sure that whenever a resource with this field enabled comes back up, it's added to that set so that Simix
50 * sees it and react accordingly. This would kill that need for surf to call simix.
