2f2421bae1 ctdb-eventscripts: CTDB_NATGW_PUBLIC_* optional on slave-only nodes
Commit 4ee4925d41 forgot about
CTDB_NATGW_SLAVE_ONLY so it introduces an incorrect failure when this
is set, and CTDB_NATGW_PUBLIC_IFACE or CTDB_NATGW_PUBLIC_IP is unset.

Relax the sanity check to see if CTDB_NATGW_SLAVE_ONLY is set.

Update the documentation to explicitly state that
CTDB_NATGW_PUBLIC_IFACE and CTDB_NATGW_PUBLIC_IP are optional and
unused if CTDB_NATGW_SLAVE_ONLY is set.  It would be possible to
insist that CTDB_NATGW_PUBLIC_IFACE and CTDB_NATGW_PUBLIC_IFACE should
be unset in that case.  However, it is more reasonable to allow
consistent configuration across nodes except with some nodes
configured slave-only.

Add tests, update infrastructure and fix a thinko in the stub's
"natgwlist" implementation.

ce8ac88b96 ctdb-tools-ctdb: Drop disconnected nodes when filtering by capability
Commit ba69742ccd missed the point of
filtering disconnected nodes while limiting the nodemap to those in
the NAT gateway group.  It was really to avoid trying to fetch
capabilities from disconnected nodes.  This should be explicitly done
in filter_nodemap_by_capabilities(), otherwise "ctdb natgwlist" simply
fails when there is a disconnected node.

Note that the alternate solution where filter_nodemap_by_flags() is
called before filter_nodemap_by_capabilities() would not be not
correct.  Filtering on flags first can produce a "healthier" set of
nodes where none of them have the NAT gateway capability.

Also extend stub for ctdb_ctrl_getcapabilities() to fail when trying
to get capabilities from a disconnected node and add a corresponding
test to confirm that "ctdb natgwlist" is no longer broken.

bafb9151cc ctdb-tests: Improve tickle tests
It is hard to diagnose failures in the NFS tickle test because there's
no way of telling if the test node doesn't have the tickle or if it
didn't get propagated.

Factor out check_tickles() into local.bash and give it some
parameters.

Have the NFS test call it first to ensure the tickle has been
registered.  Then use new function check_tickles_all() to ensure the
tickle has been propagated to all nodes.  Give this a bit of extra
time (double the timeout) just in case we're racing with the update.

Add a useful comment to the CIFS test so that I stop asking myself how
the test could ever have worked reliably.  :-)

79d2800004 ctdb-tests: Add "ctdb listnodes" and "ctdb xpnn" stub tests
Tests for xpnn need to implement a stub for ctdb_sys_have_ip().  The
cheapest way of doing this is to read a fake nodemap using the
existing code and check if the IP of the "current" node is the one
being asked about.  However, the fake state initialisation isn't
currently available to without_daemon commands because it is meant to
represent daemon state.  However, it can be made available by moving
the relevant code into a new stub for tevent_context_init().  The stub
still needs to initialise a tevent context - this can be done by
calling a lower level function.

8eb20c2347 ctdb/eventscripts: Reconfigure lock should be released quickly
Currently the lock is held until the corresponding eventscript
completes, since the process still exists.  If the regular part of an
eventscript hangs then the lock might unnecessarily be held for a long
time.  The pathological case is when a monitor event gets stuck in
D-wait state and the script times out but can't be killed so the lock
is still held.  This can cause an unwanted monitor replay.

Change this so that the lock is released immediately after the
reconfiguration is complete.

fdccaab2a9 ctdb/eventscripts: Do not reconfigure in "monitor" events
"monitor" events can be cancelled.  If a reconfigure action does a
service restart then the "monitor" event can be cancelled at the
inconvenient moment after the service is stopped.  In this case the
service stays down and the node may become unhealthy (depending on
whether there are any repair actions in the monitor event).

A long time ago we did service reconfiguration in "monitor" events
following failovers.  Service reconfiguration was then moved to the
"ipreallocated" event.  However, reconfiguration in "monitor" events
has been kept as a last resort in case an "ipreallocate" event does
not occur.  The only important case that this covers is "ctdb
deleteip", where "releaseip" events are generated without a
corresponding "ipreallocated".  Therefore, IPs can be deleted without
running the required service reconfiguration.

The supported way of removing IP addresses is now via "ctdb
reloadips", which always causes a takeover run with a corresponding
"ipreallocate" event.

This means that service reconfiguration in "monitor" events is no
longer required and should be removed because it is unsafe.

Also update the associated tests.  Make the first confirm that the
monitor event no longer does reconfiguration.  Change the others to
test that monitor status is correctly replayed when something else is
doing a reconfigure and currently holds the reconfigure lock.

318f2cf912 ctdb/tests/scripts: Simplify the top-level test scripts
At the moment run_tests.sh has quite fragile argument processing.  It
needs that annoying "--" between options and tests.  The random
default (mktemp -d) for TEST_VAR_DIR is wrong and is worked around in
various places.

Instead:

* Change the default behaviour to print a summary, add new option -N
  to turn off summary, and remove old -s option.

* Change the default behaviour to run integration tests with local
  daemons, add new options -c to run on a cluster, remove old -l
  option.

* Make $testdir/var the default if the tests are not installed, and
  $(mktemp -d ) the default if tests are installed.

* Move the default tests for local/cluster into scripts/run_tests.

run_tests.sh (and the run_cluster_tests.sh symlink) should behave as
before but with slightly more reasonable defaults.
