(This used to be ctdb commit ede79b571bf89b89f1b8394f262ca0689f8c65f3)
 2007-05-28 00:34:40 +10:00
Andrew Tridgell
d41290fbae added code to ctdb to send a tcp 'tickle' ack when we takeover an 
IP. A raw tcp ack is sent for each tcp connection held by clients
before the IP takeover.

These acks have a deliberately incorrect sequence number, and should
cause the windows client to send its own ack which will in turn cause
a tcp reset and thus cause windows clients to much more quickly
reconnect to the new node.

db4c479568 add dead node detection so that if a node does not generate any 
keepalive traffic for x seconds   it is deemed dead


this triggers a recovery after a while if a ctdbd has been STOPPED    
but it doesnt recover automatically when the node reappears

7dfdab1b9d recovery daemon 
this program is a client to the local ctdb daemon

every second it pulls all vnnmap and nodemaps from all nodes that are 
available and checks if a recovery is required

a recovery is required if :
* all nodes do NOT have an identical vnnmap and generation
* all nodes do NOT have an identical nodemap
* there are active nodes that are NOT in the nodemap
* there are nodes in the nodemap that are NOT active

During recovery,  the recovery tool will also make sure that all nodes 
know about and have created all databases.

e752f3bd97 - changed the REQ_REGISTER PDU to be a control

- added a client_id to clients, so they can be identified remotely

- added the ability to remove registered srvids

- in the list_keys code, register a temp srvid, then remove it afterwards

2b1714a521 update getvnnmap control to take a timeout parameter 
dont explicitely free the vnnmap pointer in the getvnnmap control  this 
is freed by the mem_ctx instead

add code to the recoverd to detect when/if recovery is required
veiry that the number of active nodes, the nodemap and the vnn map is 
consistent across the entire cluster and if not   trigger a recovery 
(which right now just prints "we need to do recovery" to the screen.

ebc478749b start working on a recovery daemon 
change ctdb_control so it takes a timeval pointer as argument.
this is the timeout. if the node has not responded within hte timeout
ctdb_control will return an error instead of hanging.
if the timeval pointer is NULL then the call will block indefinitely if 
there is no response.

this is used for now in the createdb control   but all the helpers 
ctdb_ctrl_* should probably be updated to take a timeout parameter as 
well.

9366120d92 changed the way set_call and attach are done so that you can safely 
attach to databases after the protocol has started. The daemon
broadcasts information on new databases to the other daemons.

This also eliminates the need for the client to know about the hash
between db name and db_id.

e21f69107f yay! finally fixed the bug that volker, ronnie and I have been chasing 
for 2 days.

The main bug was in smbd, but there was a secondary (and more subtle)
bug in ctdb that the bug in smbd exposed. When we get send a dmaster
reply, we have to correctly update the dmaster in the recipient even
if the original requst has timed out, otherwise ctdbd can get into a
loop fighting over who will handle a key.

This patch also cleans up the packet allocation, and makes ctdbd
become a real daemon.
