# Change User Description Committed
#17 19414 C. Thomas Tyler Released SDP/MultiArch/2016.1/19410 (2016/05/17).
#16 18619 Russell C. Jackson (Rusty) Updating main with current changes.
#15 18530 Russell C. Jackson (Rusty) Update main from dev.
#14 15856 C. Thomas Tyler Replaced the big license comment block with a shortened
form referencing the LICENSE file included with the SDP
package, and also by the URL for the license file in
The Workshop.
#13 15777 C. Thomas Tyler No functional changes.

Style Policing only on bash scripts only.

Normalized indentation and line breaks, removed offending tabs, and general whitespace
usage.
#12 15691 Russell C. Jackson (Rusty) Changed to always create a checkpoints.rep directory on the logs volume so that moving
the pre-rotated journal back to be the live journal will be a move operation when doing
a failover.

Added a SHAREDDATA setting to p4_vars so that I could check for that in sync_replica and
weekly_sync replica. That allowed me to delete weekly_sync_shared_replica and sync_shared_replica.

Added cleanup of checkpoints.rep to sync_replica and weekly_sync_replica since that is
where the replica journals should always be located now.

Removed cleanup of checkpoints.rep from daily and weekly backup scripts since those
should not be handling replica file clean up.

The SDP is now designed to be used with the journalcopy and p4 pull -L commands rather
than the old style replication using just pull. Failover requires that you move the
pre-rotated journal that is in the checkpoints.rep directory back to
/p4/${SDP_INSTANCE}/logs/journal now along with updating the server.id file.
#11 15609 C. Thomas Tyler Pushing SDP 2015.1.15607 (2015/09/02).
#10 15373 Russell C. Jackson (Rusty) Corrected order of ckp_running check.
#9 15190 Russell C. Jackson (Rusty) Added a semaphore file to prevent the checkpoint process from running if another one
 hasn't finished.

 Added a check to make sure the journal number is numeric.
#8 13928 dsp Set lastSDPCounter after a successfull SDP checkpoint

       p4 admin checkpoint sets lastCheckpointAction, which is useful for monitoring, in particular
       when checkpoint age should be observed from the outside through p4. However the SDP is using
       p4d directly to create checkpoints and will not set checkpoints. In order to distinguish human
       actions from the SDP cronjobs, set a new counter lastSDPCounter in a similar format.
#7 13908 C. Thomas Tyler Pushing SDP 2015.1.13906.
#6 12171 Russell C. Jackson (Rusty) Merge in changes to remove the need for p4master_run.
#5 11857 Russell C. Jackson (Rusty) Added a setting to control if checkpoints.rep gets created or not, and then
 a check to see if that directory exists. If it does, we reset CHECKPOINTS and
 run it a second time in the daily and weekly in order to keep the checkpoints.rep
 directory cleaned up when using a shared depotdata volume.
#4 11707 Robert Cowham Refactored sending of mail to a common function.
Make the setting of "MAILFROM" work for Ubuntu (GNU Mailutils) as well as CentOS
#3 11570 Russell C. Jackson (Rusty) Brought in changes from Mark Foundry to add -S $MAILFROM to mail commands.

 Changed sync_replica.sh and weekly_sync_replica.sh to use $LOGFILE for consistency.

 Added mail command to both files as well.
#2 11524 Russell C. Jackson (Rusty) Released updated version of the SDP from Dev.
#1 10148 C. Thomas Tyler Promoted the Perforce Server Deployment Package to The Workshop.
