From c9fe4af70d2c884c1f95714a81ad6d1de31d5186 Mon Sep 17 00:00:00 2001 From: Michal Schmidt Date: Tue, 14 Oct 2014 18:27:55 +0200 Subject: sd-bus: make sd_bus::reply_callbacks a OrderedHashmap The way process_closing() picks the first entry from reply_callbacks and works with it makes it likely that it cares about the order. --- src/libsystemd/sd-bus/bus-internal.h | 2 +- src/libsystemd/sd-bus/bus-slot.c | 2 +- src/libsystemd/sd-bus/sd-bus.c | 14 +++++++------- 3 files changed, 9 insertions(+), 9 deletions(-) (limited to 'src/libsystemd/sd-bus') diff --git a/src/libsystemd/sd-bus/bus-internal.h b/src/libsystemd/sd-bus/bus-internal.h index 601ea5afb1..57247d7df9 100644 --- a/src/libsystemd/sd-bus/bus-internal.h +++ b/src/libsystemd/sd-bus/bus-internal.h @@ -230,7 +230,7 @@ struct sd_bus { struct bus_match_node match_callbacks; Prioq *reply_callbacks_prioq; - Hashmap *reply_callbacks; + OrderedHashmap *reply_callbacks; LIST_HEAD(struct filter_callback, filter_callbacks); Hashmap *nodes; diff --git a/src/libsystemd/sd-bus/bus-slot.c b/src/libsystemd/sd-bus/bus-slot.c index d6793c29e9..568a6ed60c 100644 --- a/src/libsystemd/sd-bus/bus-slot.c +++ b/src/libsystemd/sd-bus/bus-slot.c @@ -75,7 +75,7 @@ void bus_slot_disconnect(sd_bus_slot *slot) { case BUS_REPLY_CALLBACK: if (slot->reply_callback.cookie != 0) - hashmap_remove(slot->bus->reply_callbacks, &slot->reply_callback.cookie); + ordered_hashmap_remove(slot->bus->reply_callbacks, &slot->reply_callback.cookie); if (slot->reply_callback.timeout != 0) prioq_remove(slot->bus->reply_callbacks_prioq, &slot->reply_callback, &slot->reply_callback.prioq_idx); diff --git a/src/libsystemd/sd-bus/sd-bus.c b/src/libsystemd/sd-bus/sd-bus.c index e677a88bac..c17b1a0a0e 100644 --- a/src/libsystemd/sd-bus/sd-bus.c +++ b/src/libsystemd/sd-bus/sd-bus.c @@ -139,7 +139,7 @@ static void bus_free(sd_bus *b) { bus_reset_queues(b); - hashmap_free_free(b->reply_callbacks); + ordered_hashmap_free_free(b->reply_callbacks); prioq_free(b->reply_callbacks_prioq); assert(b->match_callbacks.type == BUS_MATCH_ROOT); @@ -1759,7 +1759,7 @@ _public_ int sd_bus_call_async( if (!BUS_IS_OPEN(bus->state)) return -ENOTCONN; - r = hashmap_ensure_allocated(&bus->reply_callbacks, &uint64_hash_ops); + r = ordered_hashmap_ensure_allocated(&bus->reply_callbacks, &uint64_hash_ops); if (r < 0) return r; @@ -1782,7 +1782,7 @@ _public_ int sd_bus_call_async( s->reply_callback.callback = callback; s->reply_callback.cookie = BUS_MESSAGE_COOKIE(m); - r = hashmap_put(bus->reply_callbacks, &s->reply_callback.cookie, &s->reply_callback); + r = ordered_hashmap_put(bus->reply_callbacks, &s->reply_callback.cookie, &s->reply_callback); if (r < 0) { s->reply_callback.cookie = 0; return r; @@ -2096,7 +2096,7 @@ static int process_timeout(sd_bus *bus) { assert_se(prioq_pop(bus->reply_callbacks_prioq) == c); c->timeout = 0; - hashmap_remove(bus->reply_callbacks, &c->cookie); + ordered_hashmap_remove(bus->reply_callbacks, &c->cookie); c->cookie = 0; slot = container_of(c, sd_bus_slot, reply_callback); @@ -2165,7 +2165,7 @@ static int process_reply(sd_bus *bus, sd_bus_message *m) { if (m->destination && bus->unique_name && !streq_ptr(m->destination, bus->unique_name)) return 0; - c = hashmap_remove(bus->reply_callbacks, &m->reply_cookie); + c = ordered_hashmap_remove(bus->reply_callbacks, &m->reply_cookie); if (!c) return 0; @@ -2499,7 +2499,7 @@ static int process_closing(sd_bus *bus, sd_bus_message **ret) { assert(bus); assert(bus->state == BUS_CLOSING); - c = hashmap_first(bus->reply_callbacks); + c = ordered_hashmap_first(bus->reply_callbacks); if (c) { _cleanup_bus_error_free_ sd_bus_error error_buffer = SD_BUS_ERROR_NULL; sd_bus_slot *slot; @@ -2522,7 +2522,7 @@ static int process_closing(sd_bus *bus, sd_bus_message **ret) { c->timeout = 0; } - hashmap_remove(bus->reply_callbacks, &c->cookie); + ordered_hashmap_remove(bus->reply_callbacks, &c->cookie); c->cookie = 0; slot = container_of(c, sd_bus_slot, reply_callback); -- cgit v1.2.3-54-g00ecf
