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