# P4BIN - Command line client name for the instance being backed up.
# P4DBIN - Server executable name for the instance being backed up.
# P4ROOT - Server's root directory. p4/root, p4_N/root
# P4PORT - TCP/IP port for the server instance being backed up.
# P4JOURNAL - Location of the Journal for the server instance being backed up.

# Change User Description Committed
#9 26477 C. Thomas Tyler Patch to rotate_journal.sh.
Added coverage for rotate_journal.sh to test suite.
#8 26456 C. Thomas Tyler Patch to fix issue with refresh_P4ROOT_from_offline_db.sh behavior
on replicas.

Adjusted behavior for other scripts to ensure proper behaivor when run on
replicas vs. edge servers vs. the master server.

Approving patch for testing.
#7 26081 ashaikh Add support for opting out of information email messages

Currently, we're trying to filter our email to only contain actionable messages. By default, the SDP scripts will always send an email if it's configured when a job has completed. I'd like to add a parameter to suppress informational messages and only get notified if there is an error.

I kept the default behavior of always sending an email.
#6 23778 C. Thomas Tyler Removed obsolete code from recreate_db_checkpoint.sh and rotate_journal.sh.
#5 20940 Russell C. Jackson (Rusty) Drop JOURNALNUM from the rotated log names because it forces you to wait to rotate
the prior logs until you get the journal number and creates a problem where the error
that you couldn't get the journal number ends up at the end of the previous days log
file, and that is what gets email out. That causes confusion for the person trying
to see what the error is.

Moved all rotate_last_run_logs up to the point right after we set the environment.
#4 20708 C. Thomas Tyler Per discussion: s/checkpoints.rep/journals.rep/g

This directory name changed, used in the journalPrefix configurable, is
intended to clarify that the should be targeted to for a FAST volume
for use with journalcopy, rather than the LARGE volume as would be
implied when using a directory with "checkpoints" in the name.
#3 20425 C. Thomas Tyler chmod +x rotate_journal.sh.

Done with: p4 edit -t +x rotate_journal.sh.

This is just a filetype tweak; there are no content changes.

#review-20426
#2 19768 UnstoppableDrew @tom_tyler @russell_jackson
Bug fix for running p4master_run as root, and some comment header cleanup. Job 000543

p4master_run: Preserve original arguments list and use this when exec'ing as $OSUSER.

backup_functions.sh: Add text about sourcing p4_vars yourself instead of using p4master_run.

update_limites.py: Run p4login directly without p4master_run since p4login calls p4_vars now.

everything else: Remove comment block about needing to run with p4master_run. Reword comment
  about SDP_INSTANCE since it is not always an integer value.
#1 18859 Russell C. Jackson (Rusty) Created script to rotate the journal and replay it to the offline database.

Updated the crontab to run the new script before the weekly.
Updated the edge crontab to account for the time adjustment in the master crontab.
