midplane block that starts on a higher coordinate than it ends (i.e if a
block has midplanes [0010,0013] 0013 is the start even though it is
listed second in the hostlist).

It has been changed to improve the calculated value for pending
jobs and use the actual node count value for jobs that have been
started (including suspended, completed, etc.)

being in error.

will return ENOTCONN and not initialize the addr_str causing valgrind
errors.

This allows multiple job ids to hold, uhold, resume, suspend, release, etc.

Fix slurmstepd race condition when separate threads are reading and
modifying the job's environment, which can result in the slurmstepd failing
with an invalid memory reference. Observed at shutdown when trying
to run the task epilog and trying to read the env var:
SLURM_STEP_KILLED_MSG_NODE_ID

Without this patch, free() is called on a random memory location
(i.e. whatever is on the stack), which can result in slurmstepd
dying and a completed job not being purged in a timely fashion.

Fix race condition in authentication credential creation that could corrupt
memory. (NOTE: This race condition has existed since 2003 and would be
exceedingly rare.)

This is needed for job arrays with discontiguous task ID values
(e.g. "123_[1,3,5,...99999]")

Previously job arrays were only listed with their native job ID
(e.g. 123_0 listed as 123, 123_1 as 124, etc). Now lists the job ID
using both format (e.g. "123_1 (124)"). The same format is used
for job step IDs (e.g. "123_1.2 (124.2)").

This adds a mechanism to kill a hung apbasil command

Previous logic never reopened the file, preventing proper functioning
of logrotate.

Use hash function to locate job records for improved performance.

Change partition write lock to a read lock as we use a different
mechanism for hidden partitions in getting individual jobs.

Correct logic returning remaining job dependencies in job information
reported by scontrol and squeue. Eliminates vestigial descriptors with
no job ID values (e.g. "afterany"). As depdencies are removed, the
job ID values were removed from the strings, but not the descriptors.
This eliminates both. It also checks the full job ID to make sure we do
not remove "afterany:1234" when job "123" completes.

Fix race condition on batch job termination that could result in a job exit
code of 0xfffffffe if the slurmd on node zero registers its active jobs at
the same time that slurmstepd is recording the job's exit code.

proctrack/cgroup - Add locking to prevent race condition where one job step
is ending for a user or job at the same time another job stepsis starting
and the user or job container is deleted from under the starting job step.
bug 447

Substantial performance improvement for systems with Shared=YES or FORCE
and large numbers of running jobs (replace bubble sort with quick sort).
Bug 525

Original code worked only for Cray systems. For other systems it
set gres_alloc to the total number of each GRES allocated on each
node to any job

bug 511

This might have worked fine for core reservations or when there
are sufficient idle nodes to use, the the select_g_resv_test()
function clears the node bitmap for nodes that it can not use
and the reservation create logic did not restore that bitmap
after a failed resource selection attempt. This logic restores
the node bitmap on a failed call to select_g_resv_test() so we
can add nodes to the bitmap of available nodes rather than having
it repeatedly cleared.
The logic also adds some performance enhancements that I will
add to in the next commit.

Correction to hostlist parsing bug introduced in v2.6.4 for hostlists with
more than one numeric range in brackets (e.g. rack[0-3]_blade[0-63]").
bug505

Add argument to priority plugin's priority_p_reconfig function to note
when the association and QOS used_cpu_run_secs field has been reset.
Without this flag, we remove time on "scontrol setdebug" or
"scontrol setdebugflag" that can result in used_cpu_run_secs
going negative or otherwise get bad values.
Correction to logic added in commit 6d793189
bug 423

Fix to work with change logic introduced in Slurm version 2.6.3
scheduling logic which prevented Maui/Moab from starting jobs.

Add support for -W block=true	(wait for job completion)
