Back to [[OAR versions]]

====== OAR 2.5.3 ======

Release date: 2013-06-25 

===== Changelog =====
  * Add the "Name" field on the main Monika page. This is easier for the users to find there jobs.
  * Add MAX_CONCURRENT_JOB_TERMINATIONS into the oar.conf ofthe master. This limits the number of concurrent processes launched by the Almighty when the the jobs finish.
  * Bug fix in ssh key feature in oarsub.
  * Added --compact, -c option to oarstat (compact view or array jobs).
  * Improvements of the API: media upload from html forms, listing of files, security fixes, add of new configuration options, listing of the scheduled nodes into jobs, fixed bad reinitialization of the limit parameter, stress_factor, accounting...  See OAR-DOCUMENTATION-API-USER for more informations.
  * CGROUP: handle cgroup hierarchy already mounted by the OS like in Fedora 18 (by systemd in /sys/fs/cgroup) in job_resource_manager_cgroups.pl.
  * Bug fix oar-database: fix the reset function for mysql.
  * SVG version of drawgantt: all features are now implemented to replace the legacy drawgantt. Both can be installed.
  * Bug fix schedulers: rewrite schedulers with placeholders.
  * Rework default admission rules.
  * Add support to the oar_resource_init command to generate resources with a "thread" property (useful if HyperThreading is activated/used on nodes).
  * Fix stdout/stderr bug: check the allowed characters in the path given by the users.
  * Fix: the user shell (bash) didn't source /etc/bash.bashrc in batch jobs.
  * Add quota which limits the number of used resources at a time depending of the job attributes: queue, project, types, user (available with the scheduler "oar_sched_gantt_with_timesharing_and_fairsharing_and_quotas").
  * Add comments in user job STDERR files to know if a job was killed or checkpointed.
  * Add the variable $jobproperties_applied_after_validation. It can be used in an admission rule to add a constraint after the validation of the job. Ex:
<code bash>
        $jobproperties_applied_after_validation = "maintenance='off'";
</code>
So, even if all the resources have "maintenance='on'", the new jobs will be accepted but not scheduled now.
  * Add the oardel option --force-terminate-finishing-job: to use when a job is stuck in the Finishing state.
  * Bug #15911: Energy saving now waits SCHEDULER_NODE_MANAGER_IDLE_TIME for nodes that have been woken up, even if they didn't run any job.
  * Simplify job dependencies: do not check the exit code of the jobs in dependencies.
  * Admission rules: add the "estimate_job_nb_resources" function that is useful to know the number of resources that will be used by a job.
  * oarstat: add another output format that can be used by using "--format 2" or by setting "OARSTAT_DEFAULT_OUTPUT_FORMAT=2" in oar.conf.
  * oarsub: Add the capability to use the tag %jobname% in the STDOUT (-O) and/or STDERR (-E) filenames (like %jobid%).
  * bug #14935: fix timesharing jobs within a container issue
  * add schedulers with the placeholder feature.

===== Errata / Known bugs =====
  * The OAR database schema version on a fresh database install is bogus (2.5.0 instead of 2.5.2, yes: 2.5.2), which may prevent upgrade to next version to work out of the box. See [[wiki:fix_for_database_schema_version_2.5.0]]
  * OAR 2.5.3 tarball ships with the special file "./", which causes, if uncompressed as root, to change the ownership of the working directory. This is fixed for next releases.
