#29 18530 Russell C. Jackson (Rusty) Update main from dev.
#28 16155 Russell C. Jackson (Rusty) Removed check code that probably hasn't ever worked.
 Deleted mirror_ldap* since that functionality is built into the server now.
#27 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.
#26 15784 Russell C. Jackson (Rusty) Added missing bracket.
#25 15780 C. Thomas Tyler Per Robert:  Style police causing problems :)
Fixed!
#24 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.
#23 15609 C. Thomas Tyler Pushing SDP 2015.1.15607 (2015/09/02).
#22 15197 Russell C. Jackson (Rusty) Corrected versions from testing.
#21 15193 Russell C. Jackson (Rusty) Added semaphore file to indicate state of the offline database and added check into
 the backup process to fail if the state of the offline db is not good.
#20 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.
#19 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.
#18 13908 C. Thomas Tyler Pushing SDP 2015.1.13906.
#17 12171 Russell C. Jackson (Rusty) Merge in changes to remove the need for p4master_run.
#16 11950 Russell C. Jackson (Rusty) Made die function record ERROR!!!
$HOSTNAME and $P4SERVER in subject.

 Cleaned up message passed to die command and corrected a typo.
#15 11929 Russell C. Jackson (Rusty) Updated die function to just pass parameter to mail_log_file instead of echo.
#14 11919 Russell C. Jackson (Rusty) Added a SERVERID variable to p4_vars and updated backup_functions to use it.

 Changed the location and the names of the config files so that they could
 live in /p4/common/config (You're welcome Tom). The files names are:

 p4_$INSTANCE.vars
 p4_$INSTANCE.p4review.cfg

 p4_$INSTANCE.vars will now set P4REPLICA to FALSE if SERVERID matches
 MASTERNAME, otherwise it is TRUE.

 This change means that a user must change server.id now in order to change
 the role of the server rather than changing the instance vars file. This
 makes more sense to a user that is reading the admin guide about server.id
 rather than overwriting the file based on a setting that isn't in the admin guide.

 Change mkdirs to reflect all of the above changes.
#13 11908 adrian_waters Use set -u to trap unbounded variables
#12 11886 Russell C. Jackson (Rusty) Changed $prog to $0 so that we don't have to set prog in the calling functions.
#11 11766 Robert Cowham Missed a reference to $MAIL in @11758
Tweaked run_tests.sh to output more error messages on failure. Though
this still doesn't show output of individual failed commands.
#10 11758 Russell C. Jackson (Rusty) Change MAIL variable to SDPMAIL to avoid conflicts with customer variables.

 Changed sdp_sync.sh to use get_mail_opts from backup_functions to avoid
 duplicate functions.
#9 11730 Russell C. Jackson (Rusty) Moved P4SERVER variable to p4_vars so that all scripts can use it properly.
 replica_status.sh referenced it, but it wasn't working since it was only in
 backup_functions.sh
#8 11710 Russell C. Jackson (Rusty) Changed die function to call new email function.

Added su to OSUSER functionality to p4master_run to avoid problems with
 people running scripts manually as root by mistake.
