Hi all，
I am a newer for zookeeper, I use zk 3.4.5 in my program. when zk_watcher
(initialed by zk_init function) is called when zk events present, the input
paras of the function are invalid.
the type == -1, path = “”, state = 1 or 3
My src like this:
zhandle = zookeeper_init(hosts, zk_watcher, zk_timeout, NULL, NULL, 0);
static void zk_watcher(zhandle_t *zh, int type, int state, const char *path,
void *ctx)
{
...
sd_debug("path:%s, type:%d, state:%d", path, type, state);
...
}
the output of the program :
Sep 27 14:40:08 DEBUG [main] zk_watcher(672) path:, type:-1, state:3
Sep 27 14:40:08 DEBUG [main] zk_watcher(672) path:, type:-1, state:1
Sep 27 14:40:08 DEBUG [main] zk_watcher(672) path:, type:-1, state:3
Sep 27 14:40:08 DEBUG [main] zk_watcher(672) path:, type:-1, state:1
Sep 27 14:40:18 DEBUG [main] zk_watcher(672) path:, type:-1, state:3
Sep 27 14:40:18 DEBUG [main] zk_watcher(672) path:, type:-1, state:1
Sep 27 14:40:18 DEBUG [main] zk_watcher(672) path:, type:-1, state:3
Sep 27 14:40:18 DEBUG [main] zk_watcher(672) path:, type:-1, state:1
Sep 27 14:40:19 DEBUG [main] zk_watcher(672) path:, type:-1, state:3
Sep 27 14:40:19 DEBUG [main] zk_watcher(672) path:, type:-1, state:1
I want to know why the input paras are invalid, what happened in this condition?
The connection between client and server is lost or expired? whether I need
reconnect?
thanks for your help, wait for your reply.
