to guarantee a minimum runtime before preemption.

to send user signal at preemption time.

Bug 5867

These are conditions that need to remain constant until something
changes on the job to reevaluate.

Bug 6625

What was happening here is you had to not be >= operator to have the old
limits removed.  This makes it so it always happens.

Before we went up the tree to the next assoc_ptr.  As we validate an
association on the id as well as the uid the assoc_ptr was eventually
going to become invalid.  Setting it to NULL here solves a bunch of
issues with things later on.

Don't abort when the job doesn't have an association that was removed before the job was able to make it to the database.

Bug 6625

The backfill scheduler keeps a local list of job pointers. Since the
backfill scheduler yields locks, it's possible for pending jobs to be
canceled and purged in these yield periods. The backfill scheduler then
has pointers to now invalid memory, and dereferencing those pointers is
undefined behavior and may result in a segfault.

This commit prevents purging jobs while the backfill scheduler is
running.

Refactor how memory allocations are managed to accurately track
memory allocations on each node when the --mem-per-cpu option is
used and the CPU count per node varies. Also accounts for
Memory Specialization and wraps much of the logging with
a DebugFlag of SelectType

Changed the behavior of "scontrol reboot" to require the user to specify
the nodes to reboot rather than defaulting to ALL.

Bug 6465

This allows jobs to be placed on booting nodes rather than being given a
whole node even if it would have been better to wait for the node boot.

failed.

This prevents rebuilding a job's dependency string when it has at least
one invalid (never satisfied) dependency, no matter if such invalid
dependency has already been purged (after MinJobAge) or not. This can
be useful to track down the culprit invalid dependencies even after they
are gone from ctld's in-memory job list.

The flag is cleared upon a successful job dependency update or after
another job in the dependency list has been satisfied if such list is
composed with the '?' symbol (OR'ed).

Bug 5851.

Job dependencies separated by "?" (OR'ed) should make the dependant job
be independent as soon as any of the dependencies are resolved to be
satisfied. Without this patch, if an invalid (non satisfiable)
dependency was resolved before a satisfiable one, then the dependant job
would never become independent, even after the satisfiable one got
eventually resolved.

The response of the XCC raw command is always 16 bytes, we log it and return if
we don't get an answer of this size.

Bug 6743

If GRES configuration data is unavailable from gres.conf, then use the
    node's "Gres=" information slurm.conf. This will eliminate or minimize the
    gres.conf file in many situations.
bug 6761

In 0e149092 not setting the variable when job was not requesting any gres
was considered a bug. The cuda API will use all devices if the variable is
not set. If it is set to some unknown or empty value, it will use no devices.
This variable should be used only for testing purposes and ConstrainDevices=yes
in cgroup is recommended.

Bug 6412

gres plugins will setup environment for every gres in the system even if the
job has not requested it.

Bug 6412

Removed linear search, replaced with direct record references and a hashmap.
This is faster and avoids potential collisions between assoc id's and user id's.
