Hi all,

TORQUE 2.4.9 has now been officially released. It can be downloaded at http://www.clusterresources.com/downloads/torque/torque-2.4.9.tar.gz

Here is a copy of 2.4.9's CHANGELOG:

  b - Backed out enhancement for preempted jobs. This was SVN revision 3784.
      This patch cased qrun to hang and not return when executing jobs.
  e - Commited changes that changed how preempted jobs are killed.
      This change uses a SIGTERM followed by a kill_delay SIGKILL
      to give preemted jobs time to checkpoint before terminating.

  e - Patch to correctly log attempts to create a cpuset as debug messages.
      The function im_request() in src/resmom/mom_comm.c logs the message:
      pbs_mom: LOG_ERROR::im_request, about to create cpuset for job 55100.blah.
       as an error rather than a debug message (as used in src/resmom/start_exec.c).
       The fix is to replace:
       log_err(-1, id, log_buffer);
      with:
       log_ext(-1, id, log_buffer, LOG_INFO);

  b - Modified fix in qmgr.c in is_attr to check for the '.' character
      on resource attributes such as resources_available.nodect. The
      attribute is striped of the '.' and the element and just the attribute
      name is used to compare for a valid attribute.
  b - Made a fix to qmgr.c in is_attr. When checking node names against
      attribute keywords is_attr used strncmp and limited the length of the
      compare to the length of the keyword. So node names like stateless
      were tagged as an error. I replaced strncmp with strcmp. This fix was
      added to trunk first. Version 2.5.0
  b - Bugzilla bug 57. Check return value of malloc for tracejob for Linux
      (Chris Samuel - Univ. of Melbourne)
  b - fix so "gres" config gets displayed by pbsnodes
  b - use QSUBHOST as the default host for output files when no host is
      specified. (RT 7678)
  e - allow users to use cpusets and geometry requests at the same time by
      specifying both at configure time.
  b - Bugzilla bug 55. Check return value of malloc for pbs_mom for Linux
      (Chris Samuel - Univ. of Melbourne)
  e - added server parameter job_force_cancel_time. When configured to X
      seconds, a job that is still there X seconds after a qdel will be
      purged. Useful for freeing nodes from a job when one node goes down
      midjob.
  b - fixed gcc warnings reported by Skip Montanaro
  e - added RPT_BAVAIL define that allows pbs_mom to report f_bavail instead of
      f_bfree on Linux systems
  b - no longer consider -t and -T the same in qsub
  e - make PBS_O_WORKDIR accessible in the environment for prolog scripts
  e - Bugzilla 59. Applied patch to allow '=' for qdel -m.
      (Chris Samuel - Univ. of Melbourne)
  b - properly escape characters (&"'<>) in XML output)
  b - ignore port when checking host in svr_get_privilege()
  b - restore ability to parse -W x=geometry:{...,...}
  e - from Simon Toth: If no available amount is specified for a resource
      and the max limit is set, the requirement should be checked against
      the maximum only (for scheduler, bugzilla 23).
  b - check return values from fwrite in cpuset.c to avoid warnings
  e - expand acl host checking to allow * in the middle of hostnames, not
      just at the beginning. Also allow ranges like a[10-15] to mean a10,
      a11, ..., a15.

This will be posted on the website soon. Enjoy!
