which is also in an array.

Refactor the logic which checks a job array task limit and clears
the begin time at the same time as setting the wait reason to
WAIT_ARRAY_TASK_LIMIT

When one task of a job array is started, the remaining job record
copy should have it's start time cleared.

Conflicts:

	testsuite/expect/test21.32

I just ran the test suite for slurm 14.04.7, and have a few suggestions
and bugfixes:

Test 1.35 fails on our system (probably because we limit memory with
cgroups).  Changing job_mem_opt from "--mem-per-cpu=64" to
"--mem-per-cpu=192" in line 61 fixes the problem for us.

Test 1.84 fails to recognise node names like "something1-2", ending up
with node names "something1" instead.  Changing NodeName=(\w+) to
NodeName=([^\s]+) fixes the problem.

Test 1.97 reports FAILURE when it discovers that SelectTypeParameters is
not CR_PACK_NODES.  Having "exit 0" instead of "exit 1" in line 50 is
perhaps preferable.

Test 2.18 fails because the variable $partition never gets set, so no
idle nodes are found in line 215.  Setting $partition in globals.local
helps, but should not be needed, IMO.  There is a function
"default_partition" in globals that could perhaps be used.  The same
applies to test 2.19.

Test 12.2 fails on our system because the jobs get killed due to memory
limit.  Increasing the "slack" in job_mem_limit from 4 to 10 in line 269
fixes the problem for us.

Tests 21.30, 21.31 and 21.32 fails when run as a non-privileged user.
Perhaps they should test for it and exit with a warning instead, like
many other tests.

Test 22.1 fails on our system because the time zone is different from
where the test was written.  The problem is that

set midnight 1201766400

is only correct in one time zone (and unfortunately for us, not in
our :).  Perhaps one could use the GNU date command to get the correct
seconds-since-epoch regardless of time zone.  Something like

date +%s --date=2008-01-31

should do it.  Unfortunately, I don't know enough Expect (tcl?) to
suggest how to implement that.

This is a revision of commit 1f0c210f

Remove the "profile" field from the job step information record.
The information does not actually exist in the slurmctld step
record, but is passed directly from srun to the slurmd on task
launch.

ran inside the allocation can read the environment correctly.

which won't accrue time until the job is actually able to run and then
set the begin_time to time(NULL)

If the highest priority job is a job array which can not start
additional tasks due to the task count limit, do not let that
job prevent the initiation of lower priority jobs.

message opcode for easier debug.

Append subsystem name to cgroup mountpoint path extracted from
configuration file cgroup.conf. Without this patch, the script does
not execute properly and some garbage is let in cgroup filesystems.

Not a bug but a cosmetic patch to avoid double definition of variable
rmcg and uidcg.

Without this change, if the last task of a job array is started, then requeued, it will appear twice in the job array hash table, which typically results in a linked list that loops back on itself (an infinite loop)

Without this change, canceling the last task of a job array while pending could result in a fatal error due to NULL bitmap value

so when task_id_str is made we update the record in the database.
