2018-07-11ctdb-daemon: Drop the noiphost "node flags" bitmapMartin Schwenke1-3/+0
This is no longer needed because inactive/disabled nodes no longer report any available public IP addresses. Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>

2016-12-19ctdb-takeover: NoIPHostOnAllDisabled is global across clusterMartin Schwenke1-2/+2
Instead of gathering the value from all nodes, just use the value on the recovery master and have it affect all nodes. Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>

2016-12-02ctdb-ipalloc: Optimise check to see if IP is available on a nodeMartin Schwenke1-0/+1
Use a "bitmap" of available IPs for each IP address instead of walking the list of available IP addresses. For ctdb/tests/takeover/lcp2.030.sh, this improves the time taken on my laptop from: real 0m11.997s user 0m11.960s sys 0m0.000s to real 0m8.571s user 0m8.544s sys 0m0.000s So, when assigning all 900 IP addresses the improvement is about 25%. For the no-op case (where all IPs are already assigned to nodes), the extra setup adds a small fraction of a second for 900 IPs. Intermediate cases result in intermediate improvements.

2016-02-12ctdb-ipalloc: Remove most uses of struct ctdb_public_ip_list_oldMartin Schwenke1-4/+2
Where possible, this should no longer be used. struct ctdb_public_ip_list is a fixed size structure and introduces an extra level of indirection. This means one level of indirection can be dropped for known_public_ips and available_public_ips.
