so you have two problems going on. both have the same root:
zookeeper_init returns before a connection and session is established
with zookeeper, so you will not be able to fill in myid until a
connection is made. you can do something with a mutex in the watcher to
wait for a connection, or you could do something simple like:
while(zoo_state(zh_1) != ZOO_CONNECTED_STATE) {
sleep(1);
}
myid = *zoo_client_id(zh_1);
the second part of the problem is related. you need to make sure you are
connected before you do the close.

In the FAQ, there is a question
4. Is there an easy way to expire a session for testing?
And the last part of the answer reads:
In the case of testing we want to cause a problem, so to explicitly
expire a session an application connects to ZooKeeper, saves the
session id and password, creates another ZooKeeper handle with that
id and password, and then closes the new handle. Since both handles
reference the same session, the close on second handle will
invalidate the session causing a SESSION_EXPIRED on the first handle.
(I assume when it says ³creates another ZooKeeper handle² I¹m assuming it
means do that by calling init_zookeeper. Is that correct?
Here¹s my skeleton code, which doesn¹t work. ...
clientid_t myid;
clientid_t another_id;
zhandle_t zh_1;
zhandle_t zh_2;
zoo_deterministic_conn_order(1);
zh_1 = zookeeper_init ( servers, watcher, 10000, &myid, 0, 0);
if ( !zh_1 ) {
...error...
}
// Catch sigusr1 and set the havoc flag
if ( cry_havoc_and_let_loose_the_dogs_of_war ) {
memcpy ( &another_id, &myid, sizeof (clientid_t));
zh_2 = zookeeper_init ( servers, destroy_watcher, 10000,
&another_id, 0, 0);
if ( ! zh_2 ) {
.... errror ...
}
if ( !nzh ) {
... error ...
}
zookeeper_close ( zh_2); // Shouldn't I get a session expire
shortly after this?
}
But I don¹t get a session expire. Can someone tell me what I¹m doing wrong?
TIA,
