Martin Schwenke [Mon, 16 May 2011 04:23:28 +0000 (14:23 +1000)]
Eventscripts: add a synchronous synthetic reconfigure event.

In the current code services can only be reconfigured asynchronously.
This means that configuration file changes can be made, an asychronous
reconfigure event can be triggered, and it always succeeds.  Some time
later when a service is actually reconfigured then a failure may be
seen

This adds a synthetic reconfigure event that reconfigures a service
synchronously so that any failure is reported on exit.

ctdb_service_check_reconfigure() is essentially reimplemented.

If a reconfigure event is in flight and an ipreallocated or monitor
event occurs then any scheduled asynchronous reconfigure is deferred
until the next monitor cycle.  This is to avoid reconfigures trampling
on each other.  In this case a monitor event will also replay the
previous status to try to avoid exposing any temporary instability.

If a reconfigure event collides with another reconfigure event it will
exit with status 2, indicating that the reconfigure should be retried.

The reconfigure event is implemented using a subprocess to control the
exit from the synthetic event.

As before, if a monitor event causes a scheduled synchronous
reconfigure to occure then it will replay the previous status for the
service, given that a reconfigure can cause temporary instability.

started.  The TCP port check can then pollute the logs with lots of
"ERROR" messages and possibly extra debug.

This creates a flag file when a service is started (but not restarted)

"ERROR" message.  This means that until the node actually becomes
healthy we see more friendly messages.

* Netstat is run on each loop iteration when it need only be run once.

* The -a option is used to list all connections but the function only
  cares about the listening ports.  There may be many thousands of
  non-listening ports to grep through.

instead of the -a option.  It also only runs netstat once before the
main loop.

1. If it is already set then do nothing, since it might have been set
   some other way.

   The recommended "other way" would be to add a file in rc.local.d/.

2. If it is not set then set it by sourcing
   /var/ctdb/eventscript_debuglevel.

3. If this file does not exist then create it using output from "ctdb
   getdebug".

If the optional 1st argument is set to "create" then don't source an
existing file but create a new one instead - this is useful for
creating the file just once in each event run in, say, 00.ctdb.

If there's a problem getting the debug level from ctdb then it is
silently set to 0 - no use spamming logs if our debug code is
broken...
