From bf8558bc9cab35f31bccd6a55e51f121370765c4 Mon Sep 17 00:00:00 2001 From: Martin Mares Date: Sun, 16 Jan 2000 17:40:26 +0000 Subject: Converted shutdown to a kind of reconfiguration, it's no more handled as a exception in protocol state machines. Introduced a `shutdown' CLI command. Killed few reconfiguration bugs. --- nest/proto.c | 30 ++++-------------------------- 1 file changed, 4 insertions(+), 26 deletions(-) (limited to 'nest/proto.c') diff --git a/nest/proto.c b/nest/proto.c index ecf0d90..36829bf 100644 --- a/nest/proto.c +++ b/nest/proto.c @@ -30,8 +30,6 @@ static list inactive_proto_list; static list initial_proto_list; static list flush_proto_list; -static int proto_shutdown_counter; - static event *proto_flush_event; static char *p_states[] = { "DOWN", "START", "UP", "STOP" }; @@ -221,7 +219,7 @@ protos_commit(struct config *new, struct config *old, int force_reconfig) { struct proto *p = oc->proto; struct symbol *sym = cf_find_symbol(oc->name); - if (sym && sym->class == SYM_PROTO) + if (sym && sym->class == SYM_PROTO && !new->shutdown) { /* Found match, let's check if we can smoothly switch to new configuration */ nc = sym->def; @@ -236,7 +234,7 @@ protos_commit(struct config *new, struct config *old, int force_reconfig) { /* Generic attributes match, try converting them and then ask the protocol */ p->debug = nc->debug; - if (p->proto->reconfigure(p, nc)) + if (p->proto->reconfigure && p->proto->reconfigure(p, nc)) { DBG("\t%s: same\n", oc->name); p->cf = nc; @@ -247,6 +245,7 @@ protos_commit(struct config *new, struct config *old, int force_reconfig) /* Unsuccessful, force reconfig */ DBG("\t%s: power cycling\n", oc->name); p->cf_new = nc; + nc->proto = p; } else { @@ -290,7 +289,7 @@ proto_rethink_goal(struct proto *p) } /* Determine what state we want to reach */ - if (p->disabled || shutting_down || p->reconfiguring) + if (p->disabled || p->reconfiguring) p->core_goal = FS_HUNGRY; else p->core_goal = FS_HAPPY; @@ -320,25 +319,6 @@ proto_rethink_goal(struct proto *p) } } -void -protos_shutdown(void) -{ - struct proto *p, *n; - - debug("Protocol shutdown\n"); - WALK_LIST_BACKWARDS_DELSAFE(p, n, inactive_proto_list) - if (p->core_state != FS_HUNGRY || p->proto_state != PS_DOWN) - { - proto_shutdown_counter++; - proto_rethink_goal(p); - } - WALK_LIST_BACKWARDS_DELSAFE(p, n, proto_list) - { - proto_shutdown_counter++; - proto_rethink_goal(p); - } -} - void protos_dump_all(void) { @@ -389,8 +369,6 @@ proto_fell_down(struct proto *p) { DBG("Protocol %s down\n", p->name); rt_unlock_table(p->table); - if (!--proto_shutdown_counter) - protos_shutdown_notify(); proto_rethink_goal(p); } -- cgit v1.2.3
