Subject: [PATCH 221/221] protocol/client: propagte GF_EVENT_CHILD_PING only |
|
for connections to brick |
|
|
|
Two reasons: |
|
* ping responses from glusterd may not be relevant for Halo |
|
replication. Instead, it might be interested in only knowing whether |
|
the brick itself is responsive. |
|
* When a brick is killed, propagating GF_EVENT_CHILD_PING of ping |
|
response from glusterd results in GF_EVENT_DISCONNECT spuriously |
|
propagated to parent xlators. These DISCONNECT events are from the |
|
connections client establishes with glusterd as part of its |
|
reconnect logic. Without GF_EVENT_CHILD_PING, the last event |
|
propagated to parent xlators would be the first DISCONNECT event |
|
from brick and hence subsequent DISCONNECTS to glusterd are not |
|
propagated as protocol/client prevents same event being propagated |
|
to parent xlators consecutively. propagating GF_EVENT_CHILD_PING for |
|
ping responses from glusterd would change the last_sent_event to |
|
GF_EVENT_CHILD_PING and hence protocol/client cannot prevent |
|
subsequent DISCONNECT events |
